Coastal Windows fabricated (3) custom windows for us with a perfect fit and paint color to match our homes trim color. The decision was easy and not stressful after getting information starting with Erik, touring their production area, then finishing up with Spenser. The installation team was a pleasure and able to install the (3) windows in (1) day. As the glass is made elsewhere and I had custom painted exterior frames, the installation took months to complete. The finished product was well worth it! read more

We bought 6 Coastal custom vinyl replacement jalousie windows to replace our worn out old aluminum framed awning windows. The windows are constructed locally in their Mililani manufactory and we are always happy to support a local business. If you want jalousies, it seems there are no makers left on the mainland and Coastal was the only local maker we found that didn't treat jalousies (which we love for the airflow) as something they'd rather avoid. Pricing was comparable to other replacement window sellers of sliders, awnings and casements. We are very happy with the windows which our contractor was able to install without issue over a couple of days. (Coastal also offers installation but we decided to use the guys we knew and trusted over at Oahu Builders) We visited the showroom and met our started salesman (Erik) who showed us around and listened to our needs. A few days later Erik came and measured and we had a proposal soon thereafter. After several adjustments and decisions on options we placed the order. We went with simple white vinyl and 6" wide slats and added the invisible slat security feature as well. Time will tell but they look good, operate smoothly and seem easy to maintain. The inside screens are a convenient feature as well On the downside, we wish the showroom had a little more space to see additional window and door options and colors. And be advised that from order to delivery took about 4 months (as advised from the beginning) so factor that into your planning read more

TLDR: I had a wonderful experience with Coastal Windows and would immediately recommend them to anyone looking for high quality custom windows. I had a challenging project, and these folks helped me clear every obstacle with ease and kindness. The Details: The property needing new windows is in Massachusetts. I needed new Jalousie style windows as part of an upgrade/refresh project. Turns out, no one in the northeast provides this style of window any more, and no contractor or vendor knows where to source them at all. I finally started inquiring outside of the region. Plenty of manufacturers in the south, southwest and outside of the US offer this type of product, but if the quality wasn't disappointing, the customer service would be. That is, until I spoke to Clark and Tasha at Coastal Windows. They answered all of my questions, helped me choose the right product, and even helped me extend the pricing that was quoted even though I delayed my purchase due to permitting issues. Not only were they patient, knowledgeable, communicative and creative, they also found a way to have my windows shipped to the property (this is definitely not typical). On top of that, the windows were made available early and they were much better quality than I'd expected (even though my expectations were quite high). My contractor was both surprised and very impressed and ended up taking pictures and spreading the word about them. I am tremendously enjoying the finished renovation, enjoying the many compliments that I receive specifically regarding the windows, and have very much enjoyed working with Coastal Windows. I will work with them again when needed and would not hesitate to recommend them to anyone. Thank you Clark, Tasha and team! read more

I ordered a custom awning window from CW to replace an existing window. Ethan was my sales guy and he told me it would probably be about 3 months out. They got it done in half the time. I also had a broken slider window repaired which took only couple days. I really like how Ethan and company take care of their smaller customers. Their windows are of high quality construction and they are local. Support LOCAL! read more

We purchased windows and a sliding door from Coastal Windows when we were doing a total home renovation. It seemed daunting b/c of the variety of window needs we had (i.e. sliding windows, awning-style, and jalousies for different sections of the house). Our salesman Spenser S made the process way less stressful and seamless! He was also prompt with communication, very easy to work with, and didn't pressure us into any purchases. The installers were also great and finished the job quicker than I expected. read more

Great customer service from Coastal Windows! We had a door latch on our sliding door that broke after 10 years of constant use, only major problem we have had, so this speaks to the quality of Coastal Windows sliding patio door. I spoke to Sandi, who promptly scheduled a repair visit within a week. Our repair technician Jessie came right on time as scheduled, completed the repair and was able to check a few more doors and make a few other minor repairs. He was courteous, friendly and efficient. Repair cost was very reasonable. So happy we chose Coastal Windows. read more

Worked with Spenser for our replacement windows after a botched job from another local windows company. One thing I learned is- never cheap out on your home improvement.

I can always count on my salesperson Angel, who I call whenever I need assistance and he directed me to Sandi in customer service who handled the repair expeditiously.

Coastal windows botched a bay window job for my 85 year old mom. First, it took months for her order, then it was the wrong dimensions, then she was pushed to make a decision on whether to keep the incorrect window or wait for a remake. When they finally installed the quality of the install was messy and poorly done. And when asked for compensation for all the problems, she was given a $100 gift card. This was a $6k job. The manager gave excuses for the mistake but would not make any concession on the cost. Never go to this business. No star for this company ever. read more

This review is long overdue. I wanted to give a review of our experience with Costal Windows. The sliding door and awning windows that we bought in 2020 are holding up beautifully. Nothing bad can be said of the quality and workmanship of these products. This project would not have been possible without the expertise of Spenser Shimazu, who came to our house and introduced us to Costal Windows. He proficiently measured our windows and door to give us an estimate. He was our contact person through the whole experience. Spenser is humble, honest, approachable and very professional. Doing renovations can be daunting due to the inconvenience and cost, but knowing that we could call Spenser at anytime was reassuring for us throughout the process. We would not have chosen Costal Windows if it wasn't for Spenser. 5 years later we are very satisfied with Costal Windows. read more

We contacted Coastal Windows when our large 6' high x 11' wide second floor picture window broke into many pieces. Ethan was able to come to the house and give us a quote within a few days. He was very polite and respectful - not pushy at all. We explained to him that after having a single large window upstairs for over 50 years, we really wanted to replace it with another single large glass window. All of the quotes we received from several window companies (including Coastal Windows) all proposed filling the space with 2 or more windows because it was the most cost-effective and easiest option. Coastal Windows, however, was the only company that provided us a quote for replacing our window with a single large window. Despite the difficulty for installation and the estimated 6-month lead time to receive it, we chose Coastal Windows. We were pleasantly surprised to receive a call from Emily that the window had arrived and the team could install it 2 months earlier than expected! The installation was no easy task given the size of the window and the obstacles getting the glass onto our property and up the stairs to its final location. But the installation team from Coastal Windows was very efficient, cohesive and professional. Ethan was also on site to answer any questions and address any concerns that we had on installation day. He even followed up within a few days to send a team member back to fix part of our awning that needed to be removed to get the window up the stairs. Ethan was very easy to work with, attentive to our requests and responsive to our needs; and the team at Coastal Windows provided us with a great window that will enhance our home for another 50+ years! Mahalo Ethan and Coastal Windows! read more

Finally able to review. Job was completed Spring of 2021. Coastal windows replaced our 20ft living room opening with their stacking system. We are very happy and pleased. Sales process was flawless, install crew were very professional and experience the way it should be. Beyond 5 stars with Costal Windows especially after our very disappointing experience with another windows company. I highly recommend Costal Windows for all your windows replacement needs. read more

We wanted to replace our windows and wanted to have it replaced with high-quality windows. Spenser was helpful from Day 1 in letting us know what type of windows may help our needs. Becauses some of our windows had unusual dimensions, some of the windows had to be made special for us. His guidance added value and safety to our home. He followed up after to make sure we were satisified with our product. The installers were professional and efficient, and I have no problems with our windows and sliding door. I would highly recommend Coastal Windows to my friends and family. read more

I wanted to share my experience as this company deserves your consideration for your window project. I believe Coastal Windows will have your best interest as their top priority, just as they did ours through every step of the project. Our lanai went from a dusty, dirty hangout to a clean, weatherproof I-always-want-to-be-out-there living space. Our goal was to replace screened openings with windows to keep out dust, dirt and water. The more window companies I talked to the more ideas I got. However, it was not till speaking with Ernest Chang at Coastal Windows that I was convinced we were making the right decision. Ernest was very patient and actually listened to everything we wanted to achieve with our window project. He helped us work through many details and came up with a solution better than we even imagined. One wall went from 8 screened openings to 4 large sliding windows. When we started we were just going to fill the existing openings with similar size windows. That would have been a huge mistake. This alone set Coastal apart from most other companies who would basically say "tell me what you want and I will let you know how much." Coastal actually consulted and planned with us. It may sound cliche, but that old saying "you get what you pay for" holds true with Coastal Windows. You may pay a bit more, but your end result and your experience from start to finish will be better than expected. Here is what you are paying more for: top of the line windows with no moving parts to break or fail that are designed and built here on island; complete removal of old windows and installation just like new construction ensuring structural integrity and weather resistance; and a vast knowledge of our weather conditions and what works and what doesn't. Breakdown of my experience: Sales process with Ernest Chang: this guy knows his stuff and tells it like it is with amazing tact and respect. He listens to everything and actually hears what you have to say. You could tell he was less focused on the final sale and more focused on what we wanted to achieve that would make us happy. Project proposal: Straight forward and no hidden anything. I'm the guy who asks every possible question and leaves so stone unturned. Everything was communicated clearly and there were no issues or surprises throughout the process or upon completion. Also, every call and email was always returned promptly. Final measurements: These guys came in and made sure they knew exactly what they were getting into and what they would need for install day. If they felt they needed to pull a piece of trim to get a better look, they asked to do so. I am sure they knew they could, but they asked anyway. I respect that they had the consideration for us to ask more than once before just ripping into the walls. Installation: We had 6 very large windows going in and knew it would be a multi-day project. The crew from day one was kind & courteous from the moment they arrived to the moment they left. 5 full days and I never heard one inappropriate word. Now that is a huge feat to achieve with any construction project, let alone a 5-day window install in a house on a hill that has shifted and settled over the years. On top of that, their attention to detail and refusal to cut corners to ensure the best installation possible was just impressive. read more

I would like to thank Catherine, Chris, and the Coastal business office team for great customer service. We just completed 100% replacement of our home windows. Special thanks to the install team of Al, Marcus, Justice, and Sage, for the outstanding installation with attention to detail. They are very skilled craftsman doing beautiful work. read more

Went to the showroom and spoke to Erik, we set an appointment to come to my place to do and estimate. He shows up does his thing and says he will email a estimate on Wednesday when he's in the office. This was Monday when he came out. A week goes by an still nothing, not even a call or text. Then initially he gave a rough estimate of 1k per window and 1k to install each window and that was discounted 35%. This place is a rip off and found someone else to do it for 1/3 the price and they buy their surrounds from the same vender just use their own frames. Shop around people. Just because they advertise on TV doesn't make them the best. If he didn't want my business he should have just been honest up front. read more

We just had all of out windows replaced by Coastal Windows and couldn't be happier! The quality of the windows and the service that was provided was second to none. If you are interested in replacing your windows or sliding door I would highly recommend them. From our first meeting with Spencer (sales rep), to working with project manager Chris Romena and Mark Mayubay...everything went very smoothly according to plan and finished on schedule. When all the windows were installed Mark and his crew made sure that everything was done according to our expectations. I was also very impressed with how clean they left our place after everything was completed. Yes...Coastal is more pricey than some other estimates we got, but we felt we got the best value for our dollar...and peace of mind and customer service goes a long way in my book (pocketbook)!! Thank you Coastal Windows! Very Satisfied Customers, Renny and Val Pang P.S. if you going to have someone run the job, you have to ask for Mark...he's their best! read more

Emailed Catherine at Coastal. She always responds that day. She had Tasha work with me on looking at my screen door. With the high winds I couldn't shut the screen, so she scheduled an appointment. As a Senior and not so handy the office assured someone would help me fix the problem. Although a minor fix Chris was so nice changed the lock and checked the other slider for us...he also showed us how to keep the doors lubricated. That is service beyond what I asked for. Thank you, Coastal Team! read more

Their technician Manny was friendly, professional, and efficient, going above and beyond what he came out to do.

I wish I could give this company more than 5 stars. I had a great experience with Coastal, and Erik our sales rep especially. So much so that even though they were the most expensive out of all the estimates we received, we decided to go with coastal because I was convinced I was getting the best value for my money and needs. There is also a little part of me that felt good I would be supporting a local manufacturer (i mean, how many of those do we actually have here in Hawaii, really??). If you are replacing windows and sliding doors for a house to be sold soon thereafter, perhaps a cheaper window company is for you. But we plan on living in our home for the foreseeable future, so quality in product and installation were of paramount importance to us and we were not disappointed at all. Our house is about 80 yards from the ocean, so the old aluminum window and sliding door frames -- particularly those facing the ocean -- were badly rusting and corroded. The glass we had was also around 30 years old and had lots of water spots stained into the glass. So, we looked to coastal for help. Erik, the sales rep we had, was very nice and responsive to our needs. I didn't feel like I was pressured into anything and he was quick to respond to all of the very many questions I had. Coastal replaced nearly all of the windows in my house as well as 2 sliding doors. The 4-panel and 2-panel sliding doors are simply outstanding and worth the cost. The vinyl screen door is a huge improvement from the old aluminum screen door we had. The interior appearance of the windows is outstanding. With coastal, you may choose a cosmetic trim from several choices that will be installed around the window and sliding door frame. The trim we got for many of our windows, which was recommended to us by our outstanding lead installer, Cirilo, gives our windows and sliding doors a very elegant look that we very much like. (If you plan on getting plantation shutters, let the lead installer know cause you will likely have to install a flat window trim instead of a decorative window trim around the interior of the window frame to better accommodate the plantation shutter) The exterior appearance of the windows is also very nice. The exterior appearance of the vinyl frame around the window glass is different than Windows Hawaii's top of the line vinyl windows (my neighbor has Windows Hawaii's Alii windows), so it's something you should compare for yourself. One thing we really liked about coastal's windows was that the picture window portion of the slider-picture-slider windows we ordered can actually slide both left and right for a stunning unobstructed view of the ocean on the second floor of my house! It's also an important safety feature we taught our kids: They just need to slide all the windows -- including the picture window -- to one side to jump out of the window in case of a fire or other emergency. It's a lot easier to do than breaking the glass imo. Double-pane glass is likely too strong for my young kids to break in an emergency. The window screen also slides! I dont know if Windows Hawaii's picture windows in a slider-picture-slider configuration can also do that. As to installation, if you go with Coastal, I suggest being prepared to at least repaint the exterior wood trim around the window frame. The installation method coastal uses is new construction, which you should google to learn more about. Through our research we discovered Windows Hawaii, CCI, and Diamond Head Windows all do the retrofit method of installation by default. We repainted our house exterior after window installation so that wasnt a big deal to us. The installers took 6 days to complete my job (20 windows and 2 sliding doors). They were courteous and worked from 830am to 330pm everyday, with 5 or 10 minute breaks in the mid-morning and mid-afternoon, and only a half hour lunch break. These guys worked extremely hard - no laziness here! At the end of the day, they cleaned up their mess as much as possible before returning the next day, but they were out of the house consistently by 330p, so they stop work to clean about half an hour or so before 330p. We have zero regrets about going with Coastal for our windows and sliding doors needs and do not have any reservations in recommending Coastal to you. read more

I had to repair my vacation rental's sliding glass door latch as it was broken. I called to check if I could DIY it or if I'd need a service call ($80). Bridget took my info and had Chris review the photos I had emailed to her. Chris pulled the parts and when I arrived Bridget went over how to fix the latch! The customer service was fantastic but the surprise was that they replaced the parts at no charge. I am very grateful as on a tight budget due to the Covid affecting my finances. read more

I agree, beyond 5 stars. We've had our windows installed 19 years ago. After all these years, there was a crack, no problem, Receptionist Alena referred me to Customer Service rep, Tasha.

Glad I insisted that my Contractor use Coastal Windows when we purchased our home 19 years ago. read more

Non-responsive so I won't inquire with them again in the future. I'd rather see Oahu's affordable Handyman Dave!

I stopped by their store the staff was friendly and put together a quote for me and showed me several different options for my window needs I was quite taken aback at the price which was more than triple the cost of another leading competitors brand for the same quality windows. While the build is pretty much the same as much of the other competitors I guess the cost is because they build the windows here rather than somewhere else. I have no problems with the service just the price from here. read more

I didn't hire Coastal Windows but I wanted to give a shout out to them since I contacted several companies for my custom glass replacement and they were the first ones to contact me back. They were very quick to ask me how they could help and when they couldn't, they recommended another company. That was a very nice and professional thing to do. Thank you to Erik. read more

Wow!!!! This place is incredible!!! I just got locked out of our home. Was watering plants with the glass slide door closed but unlocked when I suddenly heard a "click". Long story short I got locked out due to door handle mechanism failure and had to pound loudly on the glass door for half an hour before my hard of hearing husband whom I knew wasn't wearing his hearing aids came to check out what the ruckus was all about. I frantically yelped, got a good feeling from seeing Coastal's name and messaged the business. Literally less than 5 minutes later and after their store hours, Erik messaged me back with a possible phone consultation time and a number to text a picture of the door handle to. I texted the pic since I'm in the midst of finals and received an extremely helpful reply even though the doors are not their product. All I need to do now is take the pic to the hardware store buy new handle parts and possibly screen door wheels (still need to take a pic of that with a measuring tape next to it..what a brilliant suggestion by Erik). And then hopefully soon I can be out with my watering can, and mask safely taking care of our plants again. A deep heartfelt thank you to Erik of Coastal Windows. I really really really want to get their windows and doors now because I got so much peace of mind with his excellent service already. Honey, start saving up! Our future home *will* have Coastal windows and doors!!! It's an investment worth it! p.s. This place is so fantastic that Erik is now saved in my contacts list as Erik: Coastal Windows Awesome Dude. Thank you! read more

We had been to see almost every window/door company on the island and were feeling so-so about the quality of the products we had seen, and the staff we had interacted with at most of these companies. Then we went to the Coastal Windows showroom, and we knew, right away, that this was the company we wanted to work with! Very competitive pricing with great quality, is what sold us, but equally important was the care and professionalism that we were shown by the staff. And, over time as we were working with the Coastal staff on our project, we were clearly able to see that this family run organization really puts their heart into their work, and is truly in the business of taking care of their customers. read more

Last night we had a crazy powerful rain storm with thunder/lightning. Under a flood watch so we had closed the Coastal sliding window the night before. Despite the three foot eave right above the window, the winds periodically drove sheets of rain right at the window for much of the night. Zero leakage! Just bunches of water droplets all over the outside in the morning. I inspected and saw that the weep holes that drain the water down at the bottom had done their job well. Coastal windows have lots of good size weep holes that are needed when we have torrential rain like last night. So we're real happy with the Coastal window's quality and performance. read more

We'd like to express our great satisfaction with Coastal Windows in Waipio. My wife and I had finally had it with our 40+ year old sliding doors and jalousies and wanted an upgrade in look and function. We heard many wonderful stories about Coastal Windows so we decided to give them a try. Well, they exceeded our expectations and then some. The sales team was particularly attentive to our needs as well as meticulous and precise with their measurements with our windows and doors. Our kudos to sales manager Ernest. The installation team was very professional and efficient, even replacing a termite damaged beam before installing one of the sliding doors. Work was completed on time and the clean-up was spotless. We love our new windows and doors and our dog loves her own special little window also. They are worth every penny. We could not recommend Coastal Windows more highly. read more

My boyfriend has been talking about replacing his windows for so long and the time finally came! It started with the building manager taking measurements of all the windows and handing those over to Coastal Windows. A month or two later, it was finally time to start replacing the windows. There were 7 locations that they needed to attend to: the living room, kitchen, 3 bedrooms, and a bathrooms. They brought all the materials they needed outside in the apartment building hallway and in the living room. They started with the living room and kitchen first, letting residents be able to stay in the bedrooms while the mess is going on outside. They laid down a long plastic walkway to avoid prints on the floor. They were respectful and took their shoes off. They also started the bedrooms but they didn't fully patch the outline until the next day, finishing the bedrooms first so we have a place to stay while they finish everything else. The second day, they didn't take their shoes off and the whole place was dusty. The dust was expected but they didn't continue with the plastic walkways and they had shoes inside the apartment. When they completed all the windows, I inspected the finished product. There were some peelings outside from the ceiling which I thought they'd fix but didn't. There are handprints on the white ceiling in one of the bedrooms and some parts of the frames and walls were dirty. They also forgot to insert a screen for the kitchen window but they returned a few days after. Besides that, the guys were great and quick with their work. read more
