These did not work in my apartment. I had double paned windows already installed. Before installation of my window covers, the noise in my bedroom was 45-50 dB C on average. After installation of my window covers, the noise in my bedroom is 43-50 dB C on average. These window covers only appear to maybe attenuate some medium to high frequency noise. They are not affecting overall noise levels. Any rumbling from trucks, etc, does not seem to be reduced at all. I spent over $3,000 for no reason and wish I had gone with more expensive glass window inserts instead. One reason they may not be working is because they are not properly sealed. There are gaps between the inserts and the surrounding frames. When I asked if they could fix this, they told me "no." read more

I bought 6 acrylic window covers, spending $3,000 in November 2017 (getting a small discount for having paid in cash). My main problem was noise entering through two windows in my back-end San Francisco, 2nd floor apartment - the bedroom and kitchen windows. An industrial commercial fan in the air well outside both windows emitted (and still emits) 44 decibels of noise 17 hours a day, 7 days a week, and I wanted to get a good night's sleep as I had had before the fan appeared, which was three years prior, and I did not want to have to hear the incessant hum at night. Earplugs didn't work. $300 noise-cancelling Bose earbuds didn't work. Soundproofing windows an expert told me wouldn't work either. I was desperate. The guys at Castle Window Covers measured and fitted the covers to fit both bedroom and kitchen windows and they did an excellent job of that, but the sound reduction was obviously and distinctly negligible the very instant the installers finished their work and stood back to listen. I wanted to scream that I now saw I had just wasted my money and that my attempt to soundproof my bedroom was an utter financial loss, but I suppressed the urge to scream, telling myself that maybe in time I'll appreciate better how the covers work to reduce noise. That time never came. The covers for the bedroom and kitchen windows are relatively worthless for the purpose of significantly reducing 44 decibels of fan noise or for creating an environment quiet enough to induce sleep. They should have admitted their attempt to block or reduce the fan noise was a complete failure and given me my money back on the spot. To admit failure would have cost them time and materials wasted. Eight months later, I still have to wear earplugs to bed even with the sound covers on and at other times, I have to sleep on the floor in the hallway or in the front room since the fan noise remains too intense, despite every barrier I have erected against it. The SF Department of Health finds the noise level totally acceptable. Castle Window Covers' reps suggested I might find some comfort in purchasing covers for the four windows in the front room of my apartment, a room that is well-lit and which faces the street. Before the installation, I would sometimes take my mattress into the front room to sleep when the fan got to be too much, but the loud street noises I heard were just as bad as the fan noise in my bedroom, and I was very unhappy about my overall living conditions, which lacked any real right to quiet enjoyment. The window covers the men from Castle Window Covers installed in the front room did appreciably reduce the collective volume of noise produced from the street traffic, police cars, fire engines, construction crews, motorcycles, ambulance​ sirens, parade buses, drunken pedestrians and the like, and I'm grateful to Castle Window Covers for making the suggestion and following through, even though my main objective was to reduce significantly the fan noise in my bedroom and kitchen. The guys told me they would give me a call to check on me and how I was doing with the sound reduction produced by the covers after the holidays. They never called. read more

I live in a 107 year old Victorian condo on one of the busiest streets in San Francisco in terms of cars and pedestrian traffic, with two stoplights on either end of the block and an incline. So, there's a lot of cars, acceleration, braking, motorcycles, and not to mention a fire station three blocks away - so lots of sirens. I have 6 large 67" high bay windows that are original wood and face the street. I had them restored, sashes, cords, and pulleys repaired - but they still leaked air and were completely thin when it came to sound insulation. The rooms are also adjacent to my bedroom where we have a 5 month old infant. It's illegal to replace original, street visible wood windows with anything other than identical wood, and in some cases makes no sense due to the hearty construction of the original windows: http://www.sf-planning.org/ftp/files/publications_reports/Standards_for_Window_Replacement.pdf However, this doesn't excuse them from being really poor insulators of sound and air. So, I wanted a solution that would allow me to keep the 107 year old windows but solve my sound and air problems. This seemed impossible until I did some research and found the "Magnetite" offering of window covers. In reading their description online, it seemed like the perfect fit - an unobtrusive steel rail around the interior of the window with an airtight magnet-framed piece of 1/4" acrylic glass snapped on top of it to offer no compromises with visibility or aesthetic but allow for the enhancements I wanted. I called the national number and Kenn from Castle Window Covers, a local Stockton based company gave me a call back early the next day. Kenn and his business partner came out and performed some meticulous measurements, as well as demoed the window covers to me in a sound box. Kenn was upfront and honest - I shouldn't expect the covers to completely eliminate noise, but they will be airtight and they will block out a large spectrum of frequency and overall lower the volume of noise. Within two weeks, Kenn and his partner came back and installed the window covers for 6 windows in about 3 hours. They were clean, efficient, and pleasant to have around. It has now been about 5 days since the install and I am very happy with the purchase for the following reasons: - The windows are definitely airtight now - and they also block a large amount of UV in the morning. These eastern facing windows used to let the sun in and bake my front rooms, now, while it's definitely still warm near the window, the room doesn't achieve the boiling temperatures that it used to. They also keep the temperature more normalized at night - keeping the hot air in and cool air out. - The sound is definitely a huge improvement - while I can definitely still hear road noise it has been reduced to a "mumble." I used to be able to hear car engines idling but that has disappeared, and I don't have to speak over the outsiden oises to hold a conversation. The sirens still come through pretty loud as they are on the higher end of the frequency spectrum, but it's not as piercing as it used to be. Overall, I'm happy with the purchase. I just removed one of the covers and the sound difference is tremendous. Kenn was a top-notch communicator, very genuine, the price was reasonable (and I did have a bonified quote to replace these windows with double-paned wood-clad, and can say, these were 1/4 the cost and wouldn't have given me the same enhancements. In all honesty I'd have probably gotten these covers over replacement wood windows.) Another good feature is that these windows are toddler-height with no screens. So these acrylic window covers not only protect my child from breaking the glass with his toys, they also prevent him from falling out! read more

We live on a busy street in San Francisco. We moved into a early 1900s building and recently replaced all of our windows with the double-paned ones with a sound package upgrade (windows were old and needed to be replaced - but was most excited about new windows solving the traffic noise). Thanks to SF laws/regulations, many many months and a hefty price tag later...we had new windows but still hear the traffic most of the day and night. A couple of years ago my neighbor recommended Castle Windows as she had done a ton of research, priced out competitors, etc. and was impressed with the results. I spoke to and price-compared some competitors but felt like choosing Castle was a no-brainer given all of the positive feedback and it was a CA company to boot. Kenn & Denis came to measure my windows and only a couple of weeks later - I've got window covers that you barely notice are there and the traffic noise is significant reduced. I highly recommend this company - quality products that really work and look great. read more

These guys are the absolute best. Great product, clean installation, and our home is much quieter as a result (as tested with a decibel meter as well as my own ears). The draft in the winter was fixed as well as the sound improvement, too. Impressive work all around. Kenn and Dennis are class acts and stand by the product as well. I did notice one not-so-hot review that said he expected 70-90% noise reduction. As an engineer myself, I will say one thing here- that is basically impossible. For example, if you stand 25 feet from a passenger car going 65 mph, that is 77 dB. If you cut that down by 85%, you are in a library (40 db). So that guy expected the product to make it so standing next to a 65 mph car sounds so quiet you think you are in a library? That's not possible! (unless you replaced the window with a thick soundproof wall!). So if you expect pin drop silence no matter how much noise is outside your house, nothing can help you other than moving to a remote area, honestly. But for living near noise or in a busy city, this product dramatically does reduce the noise I have found. Feel free to contact me for details if you want - we used the product on 16 windows in total! read more

I just moved into a new house, which is about 0.25 mile away from a highway. I was not used to the highway noise and it affected my working at home and my sleep quality. I did a lot of research online (reading articles and watching various Youtube channels) and compared different providers in terms of quality and service. And finally decided on Castle Windows. The quote I got from indow window was about 15% lower than the Castle Window, however, I am so happy that I chose Castle Window for the following reasons: (1) Indow window is all online service. I have to do all the measurements myself and install everything myself, while Castle Window came to do a free demo and assessment. They measured all the windows and installed them after the products are finished; (2) for Indow window, I need to wait for at least three months, compared to three weeks with Carstle; (3) the thickness of the material by Carstle is twice that by indow window; and lastly (4) for indow windows, you just push the window insets into the window frame, which would be hard to take off (as you want to make sure the fit is really tight); but Carstle window uses a steeling frame and magnetic edging, which allows to take off the window really easily. With all these benefits, I am really happy that I chose Carstle over Indow window. I was a little concerned how the window will look like after installation of these inserts; and I am very happy with the way it turns out. You can't even tell by looking there is an extra layer. It took Dennis and Charles about four hours to finishing all the installation (including windows in my three bedroom, a bathroom, and skylight). They did a really great job. Now, about the soundproof effect: I am so pleasantly surprised. My windows are double-pane already, with this extra layer of window insert, I can't hear the highway from my bedroom anymore --unless I listen really carefully! Honestly, I was not expecting the result to be this good, given the complexity of sound proof - different frequencies etc. I am so happy that I made this investment and chose the right vendor! Highly recommend! Kenn and Dennis are very nice and professional. Great customer service; kept me updated on everything. read more

Ken provided excellent service with a really great product. My room is facing an extremely loud street with Muni and lots of street noise outside. These window covers blocked way more of the noise than I was expecting- easily 60-70%. They are fairly easily detachable when I wish to open the windows. The installation was also quite pain-free. My one complaint is that the magnet is not very strong, so on windy days, which happen frequently in SF, there is often a rattling noise from the window covers partially detaching and reattaching. Other than this, I am very satisfied with the product! read more

From all of the positive reviews, we really expected better sound proofing results from these window covers. Despite the near perfect customer service from the installation company, the product itself is no miracle worker. If you live near noise, you'll still hear it after these covers are installed. I would say the noise reduction is at best 30-40%, but is nowhere near the 70-90% that other reviewers claim. There appear to be a lot of screws in the sill so if we ever wanted to remove them, there would be a lot of holes to patch. We really had high hopes for this product and spent a considerable amount of money on them. Unfortunately for us, it was a failure, and we will move forward with plans to move. read more

Product, price & service are five stars. I stumbled on these guys thanks to Yelp! After 7.5 years of living in the front of a blg located on a super busy street in SF, I was over the noise. I thought I was going to have pony up a scary amount of money to get new windows (I've heard estimates are in the tens of thousands even for small places), and they turned up in my search. The fact that their solution is significantly cheaper than new windows (Kenn said at least 1/4 the costs b/c he wanted to keep the savings 'conservative'), just as effective and also super easy to install and remove (e.g. you can just unsnap the window cover and your old set up is there), the product is a huge thumbs' up. I will say that their site does not do justice to the covers; in the site the photos seemed to make the covers look obtrustive. In real life, they're elusive. Fortunately, Kenn offered to come by (from Stockton) to walk me through some samples and details and his promises are true (we are now fully 'up & running' for the past few days). The process: after this initial visit (out of which Kenn also came up with a fixed estimate based on our window sizes), Kenn returned with his biz partner to take much more precise measurements (about 30 minutes) The third and final visit they were joined by another super friendly member of the team to do the installations. For my 800-sq foot unit (where we had 7 large-ish windows covered) the installation itself was about 4 hours as they had to remove the protective paper from the acrylic and a bunch of other stuff to make sure it was just right. And it seems to be! The reduction in noise and increased insulation are so noticeable to us. It's now peaceful to be at home! So yeah, my 7 large-ish windows were done for $2600. I would be super curious to know what new windows would cost (and frankly if they cut the noise out as much as these do anyway). Both Kenn's attentive service and great product at significantly lower cost make them a huge thumbs' up for any urban person getting a little tired with the street noises. Bonus: it seems to insulate our place better too! read more

We love these window covers... We live in on a very busy street and these covers have made our home incredibly quiet now! Now can sleep without hearing cars and traffic... So glad we found them! Best part is nobody can see them, they are virtually invisible! Love it!!! Plus Kenn and Dennis are the best! Their customer service is incredible... My wife and I highly recommend them and their products! Thanks again Kenn and Dennis! Great Work... read more

I was searching for weeks for a company to install noise reducing window inserts in my are till I found Castle randomly on a Google search. Ken was very professional, always kept me updated on the time he was arriving and provided great customer service. My inserts have been installed and they reduced the terrible traffic noise that would drive me nuts at night. I can still hear it, but it is now at a tolerable level and I can get sleep. An added bonus these inserts have reduced the draft from the window, which will lower my heating cost. Thank you so much for all your help and great customer service you have provided. read more

2 radical results: 1. the draft is gone, 2. Street noise is 95% eliminated. These guys walk their talk. They are professional, reasonably prices, customer service is 10 stars and they are passionate about the solutions they are offering with energy conservation. What's also amazing is that they are likely the best installers of office window blinds. They are precise and perfectionistic. read more

This company and their product transformed our home. We purchased our home 2.5 years ago after falling in love with the general location, quality of construction, and attention to detail. The home was smaller than we would have liked, and on a busier street than we preferred, but the seller spared no expense in it's construction. With his primary objective being to maintain the original look and feel of the house, the seller/builder ultimately decided to install double hung, dual pane Marvin windows throughout. In doing so, he was successful in maintaining the charm of the original home (built in 1926), but he overlooked the insulation quality of the double hung windows, which is notoriously poor. Due to the noise generated by our busy street, coupled with the poor insulation quality of the double hung windows, we were beginning to wonder if buying the home was a mistake. Additionally, replacing the existing (expensive and fairly new) windows with a more efficient design/product would have cost tens of thousands of dollars. After doing some research, we came across Castle Window Coverings and, to be honest, we were skeptical. Kenn and Dennis traveled from Stockton to our home in San Jose to give us a free estimate and explain the benefits of their product. Growing excited with the prospect of increasing the insulation quality of our windows, we decided to proceed with coverings for our entire second floor, but we remained skeptical. On the day of installation, the merits of their product were immediately evident. I would estimate their product cut down the traffic/airport noise entering our upstairs bedrooms by 50%. We were blown away, and the product is virtually invisible. Fast forward 18 months, and we decided to pull the trigger to have them install the same window coverings on half of the windows throughout our first floor, focusing primarily on the living, family, and dining rooms. To be honest, I was even more impressed with the second round of window coverings, because they were just as effective as the first installation, and these were now coverings in windows where we spend most of our time. Again, they're that good! Side note: upon their crew leaving after the second install, I noticed a sizeable scratch in the acrylic in one of the window coverings. I called Kenn and informed him of my findings. He assured me that they would take care of the scratch, even if that meant replacing the whole window cover. Within 24 hours, they were back at my house in San Jose (from Stockton!) to buff out the scratch, which was successful. If you are experiencing similar issues with your windows, give these guys a call. This product is truly remarkable, and their customer service, professionalism, and care in your home are just as impressive. If I could give more than 5 stars, I would. Thanks Kenn and Dennis! read more

The chill is gone! I was researching new windows for our Co-op and it looked like there would be a mountain of problems to overcome to get our window "situation" under control. With 11 units, everyone had different ideas, from putting in new windows, to not doing anything at all. Enter Kenn and Castle Window Covers. He came (several times) to show our community how new interior windows would solve many of our most pressing issues: no permitting required; extra insulation from the heat and cold; and of course, sound reduction. All big pluses. And the bonus was that each apartment could make their own decision as to whether to add them or not. Exit committee decision making! Also, money spent on energy saving windows are tax deductible. And the fact that they fabricate the windows and are responsible for their installation is another big plus over the competition. When the cold struck, I immediately noticed a difference in heat retention in my usually drafty apartment. Kenn, Dennis and crew were professional in every regard. Great communication, honest, neat and fair. They did my apartment quickly and were great at every turn. Thanks, guys! read more

We moved into a new house in San Francisco back in March. It's on a very busy street (Fell St) and the sound of the street traffic, sirens, etc. was waking me up nightly for months as I'm a light sleeper. We searched and searched and kept finding companies that might sell the windows coverings, but I'd have to install myself, which I had no time or desire to do. THEN I found castle window covers! They were easy to communicate with, they came right away for measuring that same week, and within two weeks I had all my windows fixed. It's been a week and I've slept through the night every single night without waking up to sound at all. It's a huge difference for me and my mental well-being. I highly recommend. The team was very covid-safe, kind, and professional. Even took down my existing blinds and reinstalled everything. A huge help! read more

We have a lot of very large single-paned windows in our house, and our house was always drafty and our heating bill was out-of-control. It was hard to find a solution other than paying several 10's of thousands of dollars to get all the windows double-paned. I'm so glad I finally found Castle Window Covers. We got basically all the benefits of double-panes windows at a fraction of the price and they look great. The guys who did the work - Kenn and Dennis - have been amazingly wonderful to work with. They get an A + for communication, pleasantness, dedication and follow-through. We originally hired them about 10 years ago (this review is long overdue), but we've had them back several times for small additional jobs. Every single time they've been awesome. read more

Update review Ken the owner spoke to me from my original review and I see why this place has 5 stars he was so helpful and turned my experience around was kind enough to message me and do the best to help me out will be probably doing buisness here in the future read more

I live in San Francisco near a noisy corridor and desperately needed a good night's sleep. I found Castle Windows online and asked them to add sound barriers. I am so thankful to Kenn and Dennis for providing customized window treatment with a quality product. These guys are down to earth and very professional. I got a great deal and am very satisfied. Getting a good night's sleep is priceless and something I cherish everyday. I continue to use their services as needed and always recommend them to neighbors and friends who want to maintain the beautify of their homes while benefiting from less noise. read more

I highly recommend Castle Window Covers. I live in a 1928 flat in San Francisco, with beautiful street-facing windows. However, the windows are leaky (visible air gaps) and do nothing to reduce noise on my busy street. I looked into having the windows reproduced, and was quoted $20K, not including the city permit. Additionally, the windows would need to be removed and boarded up while the reproduction work was in process. Instead, I went with Castle Window Covers at a fraction of the cost of replacement. The window covers are virtually invisible, and have drastically improved energy efficiency and noise reduction in my front room. In addition, Kenn and Dennis were great to work with, responsive and speedy. The window covers are a terrific solution! read more

Living in SOMA is exciting. However, between construction, the transit, and game-day bustle, it's a bit noisy, all hours of the day and night. At times, we could barely sleep. Not any more! Our new magnetite windows have drastically reduced the fracas and hullabaloo. The folks from Castle were polite, honest, and on-time. We can't recommend them enough. read more

You will not be disappointed!!! I just had these covers installed on a condo on a very busy street in San Francisco and the internal noise level dropped at least 60% or more. These covers are amazing, and I wish that I had them in college 30 plus years ago. The gentlemen who own and run this company are amazingly professional, reliable, kind, and helpful. Working with them has been one of the best experiences that I have ever had with a contractor, and I have worked with dozens in building my home and office. These covers are so easy to put on and take off. I quickly removed 2 of them to let air in during the day from one large window, and it was easy and quick. It is interesting that I had bug screens installed on the windows a few days after the install of these noise covers and the bug screen expert was very impressed. He had not seen them before and he asked me where he could get the Castle Window Covers. He wants to have them installed at his home near San Francisco Airport. He was impressed with the magnets that are used to hold the Castle Covers in place. read more

Highly effective noise reduction with great customer service. Effective at blocking out noise We live 1 block away from a very active train track in Pleasanton. Prior to getting my noise reduction window inserts from Castle I used to wake up 3+ times per night to the train whistle. Since getting the window inserts I haven't been woken up by the train. Good value I received a quote from another window insert provider that was 35% more expensive and I had to do the install myself! I also looked into getting replacement windows and they were 2x the cost of the Castle inserts. Great customer service Within 1 week of first calling Castle I had a quote, within 3 weeks the inserts were installed by Castle. They were very courteous with the many questions my husband and I both had about the window inserts. I also liked the noise reduction demo so I could see for myself what the inserts could do. My windows look great and I sleep much better. Thank you Castle! read more

I live on one of the busiest streets in San Francisco and the noise was driving me insane! Now with all of my windows done with these great inserts it is silent! I am amazed and thrilled. Thank you so much! It was done so quickly and efficiently and the guys are fun to work with! THANK YOU!!!! read more

I first discovered their soundproofing window covers when I lived in New Orleans. They were a game changer is a city that likes to party 24/7. I've now lived in San Francisco which in the noisy and busy Castro neighborhood. I was happy to rediscover this company and I recently had two rooms treated. It makes an incredible difference on the amount of noise reduced coming in from the streets and sidewalks. I HIGHLY recommend this product and this company! read more

I live next to the caltrain station and the noise from the trains were unbearable. As soon as I realized what a bad move I'd made I started looking for solutions. I'm glad I found Caste Window Covers. Kenn, Dennis and Ragnar were amazing and they've brought quiet back into my life. They are super friendly and did a great job installing the covers. Will use their services whenever I move to a new apartment. read more

We have a huge 5'x5' picture window that faces a really busy street (Portola Dr). Even with a double-paned window, the room was incredibly noisy, both from the traffic, and the sound reflecting from a huge condo across the street. I often work in that room, and end up feeling jangled after a few hours by all the traffic. I found these guys online: http://www.castlewindowcovers.com They had amazing Yelp reviews, so I gave them a call... Today they installed an acrylic window cover in a custom made dark brown metal frame that is held on by magnets, and it blocked at least 90% of the noise. It turned that room into someplace that is relaxing and wonderful. You can see the traffic go by, but you can't hear it anymore. You can barely tell there is anything there besides the normal window; the frame just kind of disappears. They were professional and sweet and delightful to work with. This is all they do. Highly recommended. Total cost was around $1000 installed. Apparently they work very well for insulation & air leaks too. That wasn't a problem for us, but would be another nice benefit. Ken & Dennis hail from Stockton, and install all over the Bay Area. They like to banter about the Giants--they are huge fans. :) read more

I had Castle install their product to insulate my new office in Walnut Creek from the road noise I was hearing from Ygnacio Valley Blvd. Before the install I was ready to move out of the building because of the noise; after the install the noise was cut out by probably 75% or more. You cannot even see the product as it is clearer than the glass behind it. They installed the product without drilling a single hole so it can be removed when I end my lease. I highly recommend this company -- they are incredibly responsive and professional and the finished product is fantastic. read more

These covers are well worth it! Kenn and crew are very professional and were in and out in a couple of hours of installation. We live across the street from a Muni bus station, a fire dept, and have a lot of construction in the area. We needed to make our baby's room quieter, and these sure have helped! We experienced a major reduction in noise and were surprised on how well they are working. I recommend highly, especially if you have little ones. read more

I live in San Mateo, not too far from the train station. Unfortunately there is a train that runs at 11.30pm, and another one at 4am. The noise from the train would wake us up at least once a week, and it was starting to be really annoying. I did a lot of research about noise insulation for windows, and decided to go with Castel Window Covers. The look of the window cover is pretty good, and the noise insulation is good too. I measured a noise reduction of 12 dB, which in my case means that I can still hear the train, but much less loud, so it doesn't wake us up anymore. The contractors that installed them were very professional and did a great job. And compared to other window insulation systems that I checked online, this system was actually much more affordable than any other. I have no complains so far, so I definitely recommend this window covers for noise problems. read more

Product: Fantastic - we live on a very noisy block in SF and have been waking up nightly, wearing earplugs to block the sound for 1.5 years. Now, I can sleep through the night! It is not 100% sound-proof, but the difference is amazing....you can hear low level sounds in the background, but most of the heavy wheel screeching and garbage truck noise is muted now. Very happy with the results. Service: Kenn is very professional. We contacted several service providers and Kenn was the most responsive. He was able to come see the windows, measure and install, all within two weeks of the original call. Many other providers didn't even call back or follow up. After installation, Kenn followed up with both me and my boyfriend to make sure we were happy with the product. Highly recommend Kenn for his professionalism and high level of service Price: Seems pretty in-line with other service providers we contacted. It's an expensive service, but I think well worth the price for the better quality sleep we now have. Overall - great experience, very satisfied customer. Thanks Kenn! read more

I'm a happy customer. I wish I had found Castle Window Covers earlier because we used a different company for our bedroom and that window pops out with the wind (we measured and installed ourselves). These cost a little more than that one (not significantly) and it was absolutely worth it. The process was much easier and more expedient. The customer service was great. Kenn and his crew were very responsive and kind. They know their weird SF windows. We have old curved Bay windows that nobody will replace. The draft was making our home colder on the interior than exterior. We always had the heater on and that was our main issue. We were also concerned because our little ones were always pulling up on the old windows and there is probably lead dust. The significant reduction in street noise is a plus. The inserts look great. I'll recommend to all my friends with similar issues. read more

These window covers are amazing! We love on a busy street and now the inside of our house is quiet! Our baby sleeps peacefully now that we have these window covers. This company is very courteous and professional. They are timely, clean, and excellent craftsmen. I recommend them to everyone! read more

This review is long overdue. Castle came to our home in Sacramento, CA in August of 2017. We had interior storm windows placed over our existing single pane wood windows in our 1910 home. We had the heavier noise insulating covers placed on the side of our home facing an alley. I am kicking myself for not doing this years ago. I immediately noticed the reduction in noise and the more even temperature distribution in home. Our central air and heat does not have to work as hard to keep our home comfortable. We had several window made in two sections so we can easily open the original window for evening air flow. I had double pane windows in an earlier home and the combination of an interior storm over a single pane historic wood window is far superior to a double pane modern window. Ken and his team arrived on time, were extremely professional and kind to my home. They cleaned up all the dust and even re-hung my curtains. They did 13 windows in about 5 hours. I am extremely happy with the results. If you have an old home, do NOT replace your original wood windows, installing interior storm windows is the better option - superior noise mitigation and temperature control and about half the cost (or less) of new windows. read more

I live in urban Sacramento and I'm very sensitive to road noise, ACs, generators, etc. One particular mechanical sound from a neighboring establishment was driving me nuts. I did extensive research regarding window inserts and chose to go with Ken and Castle Window Covers. Ken has great customer service - will work around your schedule. The product is amazing, my bedroom is so peacefully quiet. I had three inserts installed and it makes a huge difference. Great price, too. Wish I had gotten them a long time ago! Highly recommended if you are seeking to reduce outside noises in your home. Thanks Ken! read more

I am very happy with the results of having these window covers installed. The covers are very effective. Kenn and Dennis are great - very nice and professional. Before the window covers, I heard a hum from a building vent down the street, and I could hear cars driving up and down the street. Now, the hum is gone and the cars driving downhill are virtually silent. I can still hear cars driving up the hill, but that is understandable - at least the sound is much more muffled now. The frequencies that were bothering me are cut out by the covers and now I feel more at ease. I would highly recommend their services. The whole process was very smooth, affordable, and took only a few weeks from the first call to the installation. read more

Castle Window Covers provided a great solution to our noise problem in SoMA. Kenn did a great job giving us all the information about their product. The service was very professional, they are very serious about appointments, constantly confirming times. The first appointment had the purpose of showing us a sample of the covers, how they work and evaluating the windows, taking measurements. Some companies rely on customers taking the measurements and also installing the covers. Castle Window covers does all that for you, so there was no uncertainty. The covers were ready within a week and they came to install them. That was a pretty straight forward job, they got three technicians to do it within a couple of hours. The results are pretty impressive, and we have been sleeping much better. I recommend Castle Window covers to anyone in the SF Bay area, they are a local company and provide a great product and great service. Well done guys! read more
