We completed a residential insulation removal and install project with Gonzalo and Marko.  They were efficient in their work and provided some great insight (not exactly a straightforward project). We coordinated with a roofing contractor on access and they all worked well together. Great people to work with and I would work with them again on any future projects. read more

My realtor gave me their Referrral. They are very friendly and honest. Mr. Gonzalo came for attic insulation inspection and he gave me honest feedback about the condition and I showed him the other company EM energy and air that does insulation and HVAC both. He told me to go one company that does all. I liked his honesty. I highly recommend this company. read more

for 800 sq ft condo - their price was HALF what 2 other insulation contractors quoted me. Very professional starting from the quote (Kevin) - who explained the process, to the guys that showed up this morning - vacuumed afterwards - my house is sooo quiet - can't wait to see how it retains the heat on these colder evenings. Highly recommend them. read more

Just finished a cellulose install yesterday. Marco was able to move up my time from later this week. I was glad to get it done on the weekend. The two techs who did the job were very quick and professional. Initially I was not sure what to get, I just knew the insulation I had in the attic was insufficient. I appreciated the no nonsense bid, which ended up being the least expensive of the three which came back. I'm in Campbell and wanted to use someone close by. I'm glad it worked out that they were also the best! read more

Marko with Universal Insulation is knowledgeable, professional, and honest. After meeting with several other insulation installers, we decided to hire Universal to install R-44 blown cellulose insulation in our attic. The team showed up on time, laid drop clothes from the front door to the attic entrance and took great care running the hose around our walls and furniture. The process itself was surprisingly fast and quiet (compared with our experience having the old insulation removed by another company which took all day and was SO loud). We had been burned recently by a contractor who did a shoddy job in a part of the house we don't access very often (the crawlspace), so we made a point of checking the attic before Universal's installation team departed. R-44 is supposed to be 12" deep. We found that the insulation was not that deep near the attic entrance, so the team ran their hose back up and added more without a fuss. They also added a few cardboard rulers throughout the attic so we could see from a distance that the depth was accurate. Marko even gave us a call afterward to confirm that he had counted the insulation packages to make sure the correct amount was added. So thanks to Marko and his team for wanting to make sure the customer is happy - we are. And we highly recommend Universal Insulation. read more

Marko and his team are the best professional services we have ever experienced. I had a few estimates from other companies before meeting with Marko. His knowledge, professional attitude and honest opinion made me decided to hire his team for the insulation work. The team came on time of the appointment, drill all the holes around the houses and completed the insulation in less than 2 days. The work was neat and quick, and they had the best quote out of all the quotes I have received from all other companies. We are very happy with their work and highly recommend their services to anyone looking for insulation services. read more

I am excited to see what Universal Insulation & Building will do to our Attic. Honestly, my husband and I were so impressed by Kevin who came out to discuss the project with us. We were both so impressed with His professionalism and his manner of exhibiting sincerity that the work that their company will do will certainly meet or exceed our expectations. His presentation was not rushed, he took time in the attic to assure all needs were identified. He was open to discussion of different topics and in some ways he enlightened us and help us see and come to some decisions that we saw could benefit us at this time, Thank you Kevin for not pushing us like those other folks and being patient with us. Excellent costumer service! read more

Thank you to Marko and his team for an excellent experience. Very professional, on time, and cost effective under quote. Highly recommended for home insulation. Wish they did other work read more

I will rate this firm 5 stars just for Kevin's honesty and integrity (their work was good too). I knew I needed attic insulation upgrade because I could see that the existing blown-in insulation was pretty low. I called three of the top 5 star reviewed companies near my area before calling Universal. Each of them tried to up-sell thousands of dollars worth duct replacement work because there was asbestos in the boot. I did some online research and found that unless they were in friable condition(which they were not), they posed no risk. These firms also were recommending batt insulation even though blown-in provides better attic insulation. I later realized this was so that they could include another $2000 worth cleaning of the existing insulation. Kevin gave me the most sensible advise - to just add more blown-in insulation on top of the existing insulation saving me thousands of dollars. He also reassured me that the asbestos in the boots don't pose any risk in their present condition. The workers arrived on the scheduled date and finished the work in a couple of hours. But be sure that you over-communicate and double check things with them. They did not place a batt wall around the hole in the ceiling above the furnace closet even after I had asked one of the workers to do so. Luckily I spotted it before they had sprayed all over that portion of the attic and got it taken care of. read more

I feel so guilty if I do not write a review. I got an estimate from a company for over 3 times more than universal insulation. Gonzalo is doing the estimate and making arrangement for appointment. He is very knowledgeable, friendly. The date we agreed to install the insulation,Ricky drilled holes and found out insulation was in the wall. In the end, they didn't charge me at all. Nowadays universal insulation is the only company to honor " honesty is the best policy"! Universal insulation is the champion. read more

Incredible professionalism and integrity. Quick and efficient inspection and they basically told me that the benefit from their work would not help me on what I was looking for. I was very happy to see that level of honesty read more

Cannot say enough nice things about Jennifer and Marko of Universal Insulation. Friendly, 'on top of things' and highly professional. Marko came out to my house and spent well over an hour to measure and determine requirements. He used various instruments to determine if my existing insulation, installed many years, was still adequate. Well, after all this effort he essentially said I was fine with existing insulation. How many contractors would pass up business simply because the truth is you don't need the work? Jennifer was a pleasure to deal with. Very friendly, right there with the information you need with follow ups for appointments, etc This review is about how refreshing it is to deal with honest, professional people even though no work was done. A previous reviewer said this was a 10 Star company. I'll go along with that. Highly Recommend. read more

Amazing and responsive crew. The owner came in after the mitigation company that cleaned up the flood in our home and guided us through the process. They squeezed us into their schedule because they knew we had a baby at home. The morning they were scheduled to come in, Gonzalo called to let me know that a crew member called in sick and that he will be coming himself. I'd recommend Universal Insulation to both friends/family and my clients. read more

Ours is a 1958 tract home with no air conditioning. I couldn't remember when (or if) the attic had been insulated since we bought it in 1979, but felt now was the time to have this job done. I chose Universal based on Yelp reviews. Marko gave me an estimate after walking the perimeter -- is that the right term? -- to measure the square footage. His courteous, professional crew arrived on time, blew in the insulation in a careful and thorough manner, and answered my questions. When a drywall-repair person climbed into the attic a week or so later, he commented on the quality of the insulation! Oh, and our house feels noticeably cooler. I highly recommend Universal Insulation. read more

We had a great experience with Universal Insulation. We got the cellulose insulation blown into our attic. Gonzalo helped us with the quote, patiently answered our questions, gave us multiple options and helped to pick the best one. On the day of insulation, the technicians showed up on time, were very professional and respectful of the home. I would be happy to work with them on any future projects. read more

Totally impressed how professional this company was when I got the insulation done in my house. We had a little issues were the sheet rock didn't have enough screws in it from the prior owner and when they used the equipment to pump and the insulation from the outside of my home it caused a big crack under my window but they totally took care of it down to texturing and painting . Marko made it look like nothing ever happened. Also after setting up the appointment to the job being completed just took a couple business days and the customer service and liability was not even stressful it was the best decision I've made. After the work was completed our walls were much warmer I didn't have a moisture content from being so cold outside And the heater going inside will always cause cold moisture on the walls but now that's all gone. I can't wait to see how this is going to react during summer time. Thank you Marko for a wonderful job and the professional service you provided. read more

These folks did my attic and blow-in back in 2009, so I called them to see if they would be able to bid on my floor. Marko explained that floor insulation is rarely worth it, and that since I was also having problems with drafts through the floor insulation wouldn't solve that. He told e that caulking would be more likely to fit my needs, and said that his company didn't do that work. Marko talked himself out of a job to make sure I stayed a happy customer. read more

I do appreciate the professional who came to check the insulation in my house. He gave me so many handy tips and also helped change the air filter in my house which was definitely not his job. read more

Just did the wall insulation with Universal Insulation. Ganzalo helped do the estimate of our house and he was knowledgable and decent. The crew came to do the installation was also great. They are careful and patient. They opned the holes on the exterior wall and blow in the insulation then patched the wall. And they've also cleaned all the spots after. All I need to do is to paint it after the patch dry. Their price is really reasonable and I feel that I can fully trust their work. Highly recommended! read more

They arrived on time and really warmly explained everything. Pretty high efficiency and clean up all the dust.

This company did insulation in our house on 13th Dec. They didn't do what they were supposed to do mentioned in the work order. Now the insulation materials is falling into the kitchen and other rooms through the vents. They are not even answering my calls. read more

We live in an older home with no insulation. They came by and in one day made a huge difference to our house by blowing in insulation into the walls from the outside. Much better now! They did a good job plugging the holes they drilled in the wood siding and after I painted over them no one could tell they were ever there. Wish I would have done this years ago. read more

The work was OK but be sure that you are present and monitor that everything is done perfect the first time because you won't get it fixed later. The good: I scheduled an appointment and Kevin showed up on time. He also promptly sent a quote. The crew showed up on schedule too. The price was surprisingly fair. The bad: I had to leave so I left them insulating the house. The house was built in 1959 so there was no insulation in the house. They insulated the back (South) wall and the East wall. The crew also insulated the West wall, at last part of it. They insulated from the back up to the fence/gate. The distance from the gate to the front of the house was skipped. They drilled 3 holes in the front but clearly didn't insulate the wall. This is VERY odd since the rest of the house, including areas that were remodeled, didn't have insulation and the front had never been touched. Combine that with the area skipped on the West side and I am skeptical about the claim that it was insulated (details below). In addition, they didn't prime the holes as specified on the quote. The stucco patch looks good but the wood clearly isn't primed. I called Kevin, he returned my call the next evening and left a voice message that the wall was insulated so they skipped it. He also said that they were going to deduct it from the bill. I called back and left a message that we needed to talk because they skipped part of the West wall, didn't prime the patches, and as a result I am skeptical about the front wall. Kevin didn't call back. I called a 2nd time and again left a message. AGAIN, no call back. They eventually sent the bill. It arrived over 2 weeks after the work was done. They had adjusted it for the reduced area but it is very slow in arriving. That wouldn't be a problem if there wasn't a 30 day limit for submission of the rebate request to PG&E. Summary: Overall I think that they did reasonable work BUT I would recommend that you be present and monitor all of the work. DO NOT expect them to correct any errors because they won't respond to you again. PLUS, be prepared to process any PG&E claim very quickly on your end because they will not get you the billing information promptly so you can make the deadlines. read more

This company was very thorough and professional, beginning with Kevin coming to quote. I called several companies to get quotes on wall and attic insulation since I was not sure if our walls had insulation and figured the attic could use an upgrade. We recently bought our home as an REO so we got no info and since our home was built mid 70s, wall insulation was possible, but not guaranteed. Anyway Kevin came in, took a look in the attic, educated me on what we had and what we could do. He even told me to take incense and walk around all the light vents and door jams to see where there are other leaks. Kevin then also asked to see a closet that faced an exterior wall. He had a tool that made a 1/2 inch hole through the drywall to see if there was insulation in the walls. For sure there was, very obvious when you can see it right there! Then Kevin patched the hole with a little plug, and instantly wrote up a quote for attic insulation only. Not only did he write up the quote right away, but he educated me on all the rebates we would qualify for, giving me a quick instruction sheet to keep. I had other companies come to quote. Only one other even tried to check our walls and his method was taking off an electrical outlet cover and squeezing a wire with tiny hook between the electrical box and the drywall. He banged it around in there hoping to catch a piece of insulation in his hook. Not as effective a method as Kevin's. So when I hired Universal to insulate the attic, they were quick (2 hours) and clean. They laid down drop clothes everywhere they were walking and routing the tube and they even swept up my house afterward. Very happy and the difference with the new attic insulation was noted the first night. Such a noticeable change just in how the upstairs felt much less how much energy we saved not having to heat. read more

Honest and Professional. They inspect my house today and told me there's nothing I need to do. I just bought a old house and I am looking to install some insulation. They come, take a look, and help me to figure out whether the wall is insulated. They can lie to me, or try to sell me something I don't need. But they don't. They are so honest and professional. They even recommend me to replace the window to get better insulation (but they don't do window replacement). They run this business honestly. It's something deserve to consider these days. FYI, they charge $0 for the inspection. It's a 30 mins job and they educate me --- saving me thousands of bucks. Thanks yelp for helping me find such a good business in town. read more

The BEST insulation ever! This is my second time hiring them. The first time with our first house and now this new house. My house was so cold, but after it was warm. Before I hired Kevin again, my husband called another place because it was a 4 years gap since we hired Universal and wanted to compare other options if there are any cheaper and better quality. Wrong! Stick to Universal Insulation. They do work with a heart and honesty is their policy. We had a few rat poop in the attic and the other company told me to remove everything because I had rat infested poop up there and showed me pictures of it (which I later found out there wasn't much because my husband climbed up to check). Kevin said my attic was clean and there wasn't much installation needed like the other attic company that try to up-sell me saying I needed to put insulation on the ground and through the walls. I only needed in my attic like Kevin suggest and it worked! I was confused over fiberglass vs cellulose, but after all the crazy research I went with cellulose just like my last house and Kevin's recommendation. He may not look professional, but he does the work. The other guy came in with gears and all, but try to scare you with fake pictures from other people's attic that shows rat infested poop! Be careful what those other company tells you because they are lying. You have to climb up the attic to look for yourself because some of them trick you with pictures that aren't from your house mixed in there. Good thing, my husband was willing to climb up there. You can't go wrong with universal insulation. Will hire again if we ever move again. read more

We had a portion of our walls and attic insulated with Universal through Sandium. They worked quickly and left the place really clean. The outside was spotless after the wall insulation and they broom-swept the house after the attic, so I still vacuumed with a hepa filter afterwards, because dust... They actually found I had insulation in some of the walls so they refunded some of the money. Yay! I had to communicate this with Sandium myself because it had slipped through the cracks, but all in all I'm really happy with the company and the work they did. read more

As a longtime Realtor and real estate investor I have worked with many companies in this industry and can appreciate a truly professional company. I spoke to Marko (owner) about adding insulation to some walls of a multi-family building remodel I was working on (the lack of insulation made it easy to hear the neighbor's conversations). Marko's guys came out and based on how organized and thoughtful they were I could tell within the first few minutes that it was going to be a positive experience. They were not only professional throughout the process but they left the house cleaner than when they started. The difference in the sound proofing is truly amazing and best of all, they were the most reasonably priced company I called! I will not only use Marko and his team on my next project but will be sure to recommend him to all of my clients who are looking for a truly professional insulation company. Thanks Marko! read more

Universal Insulation - Wall insulation - Insulation Installation Near Me - Campbell, California

Did the insulation quickly. Had a little hiccup, but Marko was on top of it, everything fixed and effective. Great support,

I got the outer walls of my 50 year-old house insulated using cellulose insulation. Kevin and Kline (yes, I know, :-)) arrived promptly at 9 AM as scheduled and got the work done by 1 PM without taking a lunch break. The work was done efficiently and with minimum noise. A portion of the house did have insulation (as part of an upgrade to a couple of rooms) and when this was discovered (by them drilling holes) they took measurements and said that I would be sent an amended bill to take into account the reduced work. Overall, I'm really happy with the work done. The improvement in the insulation in my house is just great. Not only is the the house warmer in the winter but the outside sounds have been reduced because of the added insulation. My amended bill was about $840/- for a 1340 sq. ft house. PG & E rebate was about $420! I'd highly recommend wall insulation to anyone living in an older house and Universal Insulation & Building. BTW, I did get a second estimate for this and their price was almost $900/- higher than UI & B. read more

Their rep gave the quote then they were able to schedule the work for the following week. Our walls had NO insulation, but our attic was fine so we had the walls insulated to R-13 (for PG&E rebate). The crew showed up on time, and they were great with my young child (who was VERY curious about the holes in the house and the process of sealing the holes, etc). When they tell you to be diligent about sealing around every wall outlet, window sill, gap, nook and cranny that could let in even the slightest draft, BELIEVE THEM. I was totally anal about it, and the house came out just fine. However, I didn't even think about sealing anything out in the garage, and we had bits of cellulose fluff dancing around the garage for weeks. You do NOT want that mess in your house! The only thing I didn't like was the cigarette smoke that wafted into the house occasionally, and a few cig butts I found in my driveway afterward. But, the work was done on time and I am happy with the results. The smoke/butts is the only reason they did not get five stars from me. The hardest part for me was finding a few child-free hours to paint the sealed holes after the work was done. :) read more

Just got my house insulated by Universal today. Yes, it'll take a while to see how much it helps my heating and cooling, but they did the extra things that made me want to write this review. The job: This was for external wall insulation only on my stucco-sided home. 1350sq ft house, cost was $1257 (can get 3% discount for cash), and they say I'll get about a $600 rebate from PG&E. So net I'd be out about $650. The good: After I had him come out and quote, I noticed my newly remodeled bathroom had no ceiling insulation. I asked them if I could have that done at the same time. He first suggested he could quote the ceiling area but after I explained the rest of the ceiling insulation was fairly new he said to just tell the 2 workers about it and give them an extra $20 each and they'd do it. Seemed well worth it. When Kevin and Keith (or maybe it was Kline) showed up, I mentioned how there's a void between my walls and my fireplace chimeney and there's nothing I could do about that yes? He said, no they can fill that, and just did, no extra charge. They also redid my attic access hatch's insulation without me asking. Not bad eh? What else: Aside from that they were nice guys, and the whole thing took about 5 hours (plus 1/2 hr or so for lunch.) The process is fairly noisy if you're in the house and you will find a few little wisps of insulation around the outside of the house even though they do clean up. They patch the walls and put a textured paintable top coat, but don't paint them. That makes sense as it takes 2 days for the patches to dry (and during the quote they made it clear that was the plan.) Keith even patched a hole on request that my fence had made in my stucco. One thing that hadn't been mentioned is they use your 220V electrical for their insulation machine (plugged into my dryer's plug.) Not a problem, but it does make you hesitate to leave home while they're working. Note that Keith is also a painter, so you could probably get him to come back and pain the holes if you wanted (didn't ask, its easy to do myself.) I tipped them $20 each (beyond the $20 extra mentioned above) as I was impressed with them overall. read more

We live in a Glenmoor house, built in 1962. No insulation left in the attic to speak of, and of course none in the walls at all. We called on Kevin and were completely satisfied with his honesty, prompt service, and his team's work. What a great experience - I would highly recommend his services to any homeowner who needs any sort of insulation work done. Universal is thorough, fairly priced, responsive, and does a great professional job. Best part of all: our PG&E bills are half, I'm not kidding HALF, of what they were before Kevin did his thing! Highly recommended. read more

Very good pricing and results. UI did my attic and walls. They blew in cellulose. I was worried about the stucco match from the outside, but after the touch up paint I can't even tell. Much cooler home in the summer time. GREAT SUCCESS!!! read more

Insulated our attic, House feels a ton warmer. I wanted to insulate the walls, but Kevin came over made a small hole in the closet and told me that there was insulation there already so no need. So we just did the attic. Very glad i did so far. read more

This is a 10 stars business. Probably the best in California. They are very honest, will give you best advice. I had insulation installed once, it was great. A year after I got a water leak that damage my ceiling with a lot of insulation. They accommodated a time to come back to assess the situation, and gave me a couple of bags of insulation for no charge so I can fill up the empty area in my attic. I recommended them to my coworkers. After the appointment my coworkers confirmed they are the most honest, and the best among all the estimates they got to do the job. read more

I have two rooms facing south that heats up in the summer and freezes in the winter. I lived and accepted that for over 10yrs. Until recently I thought insulation involved tearing down interior walls to install rolled insulation. Then I found out the method of blowing cellulose fibers into the walls. I got all the exterior walls insulated. They come and hammer about 1 inch holes at the top and bottom and blow R13 insulation. Then patch the holes. The painting is your responsibility as expected so know your paint colors. Be warn there's going to be a lot of patch holes. The outcome is truly amazing. The whole place is a consistent temperature. When it was in the high 80s last week the two rooms were perfect like the other rooms. I'm a believer and preach this new found insulation knowledge! read more

I'd like to say that I am a loyal customer of Universal Insulation. I used them for the first time in October 2013 to have all the exterior walls insulated on my house. I called on them again to insulate my grandparents house (walls & attic) in October 2020. Just today, I had them come back out to my house to re-insulate my attic to R-60 with blown cellulose. The entire crew is great. They are professional, punctual, provide excellent service, and get the job done in record time. They have very competitive pricing as well. I worked with Gonzalo who was the estimator and I've also worked with Marko the owner. They are both great people. Rick the technician is actually the same person who has handled all my jobs going all the way back to 2013. He's very knowledgeable for sure and knows what he is doing. If you're looking to upgrade the insulation in your house and maximize your energy efficiency, I would highly recommend Universal Insulation. They will not disappoint. Bonus points to them for being able to get my job done two and a half weeks ahead of schedule. read more

Scheduled one month in advance, called and confirmed again the day before, took one day off from work ... then no show. Are you joking? Called them and found out them never scheduled my work. They told me that they messed up with another job with the same first name and $ amount and on the same day. Rescheduled next week. The crew came without advance notice and finished the job in just one hour for a 1700 sq ft attic. No promised clean up, just straight blowing in the cellulose. read more

Kevin came out to take a look at the walls and attic and fortunately, I had insulation in most of the house but none in the attic. Due to the location of my home (way up in the hills) Kevin's equipment was not able to reach my home. He did however give me tremendous tips and a quick walk-through on how to do insulate myself. A truly outstanding person, I would highly recommend Universal for their amazing customer service. read more
