The insulation in my crawlspace under the house was consistently wet and after getting plumber to come out to confirm there's no pipe leak, I decided to ask ChatGPT, it told me that prolonged wet insulation will create problems long time and that I should install something like a vapor barrier. I found insulation labs and Ray came out for an estimate. He told me the same thing as ChatGPT did so it confirmed my suspicions. His quote was definitely on the expensive side compare to a competitors quote but he did mention that his quote is expensive because they use 12mm thick vapor barriers which is more resistant. The other competitor quoted me around half the price but for 6mm barriers. I again asked ChatGPT and it told me that 12mm is preferred because 6mm is prone to breaking once a contractor or someone go down to the crawlspace and when that happens it loses its purpose to control vapor. As a result I went with insulations labs and they spent a day putting it in. So far I haven't seen any issues and I believe they have done a good job from the pictures they shared read more

Very professional and timely. They gave a fair price quote and the insulation and cleanup of attic was very nicely done to my satisfaction. They even have a crew ready incase something goes wrong to help address any/all issues. Production manager Luis is very nice and helpful. Armando the on-site manager was very professional. Communicated at every step of the way to make sure I was happy with each step before proceeding. Some things that didn't go as smooth: 1. Communication between Sales and Operations 2. Restrictions based on house layout not communicated well. read more

Insulation Labs thoroughly cleaned my attic and installed batt insulation, and I'm very happy with the work. Carlos and his crew were very nice, answered all of my questions, and after they were done, and they cleaned so well, it was almost like they were never there. When an issue arose with my doorbell, Sagi, my point of contact, sent an electrician and it was fixed the same day. I also got a ton of pictures of the job in various stages of completion. All in all, Insulation Labs gets my highest recommendation. read more

Insulation Labs - Insulation Installation Near Me - Los Angeles, California

Here's my honest review of my recent insulation service by Insulation Labs. 1. Estimate - Scheduling a sales rep to come to my home and provide me an estimate was very easy through the yelp 'Request pricing and availability' feature. The sales rep, Ethan, made some claims that were not factual about the "Energy efficient home improvement credit" but thankfully I did my research beforehand and knew the insulation would qualify me for a tax credit UP TO $600 (not $3,xxx or whatever crazy high amount he mentioned). I also felt like I was deceived into signing my estimate - I didn't know signing it would essentially confirm that I was going to accept the job by Insulation Labs. Thankfully their estimate came out the lowest out of the 3 or 4 companies I vetted but still a pretty sneaky tactic to say that I needed to sign in order to SEE/VIEW the estimate when, in reality, it was to sign and accept the job. 2. Insulation install - This was a mixed bag. I say this because scheduling the insulation install with Angel "project manager" was a massive headache. Long story short, our first appointment date was missed as Angel put the wrong date in their calendar. Eventually, the team came to install the insulation. The team was thorough in completing all of the work that was discussed during the estimate, HOWEVER, they did break one section of drywall in our ceiling where one of our recessed lights was AND one of the guys accidentally kicked the drainage line for our mini split/AC inverter which caused water to leak into our son's room and damaged the drywall in the ceiling for that room. (see photos for reference). 3. Repairing the damage - Angel was the only person I was in contact with to have our drywall repaired. More scheduling hiccups but eventually, we had a drywall contractor show up (late) and repair the first drywall issue on one day and then the other drywall issues in our son's room another day. I ended up having to call my a/c guy to fix the broken drainage line but Insulation Labs ended up reimbursing me for that cost that I paid out of pocket. Summary: After several scheduling and communications issues, I would say I'm satisfied with the actual insulation in my house and garage. In terms of the interactions and logistics of this whole process, I would go elsewhere if you enjoy your sanity. I would not recommend Insulation Labs for your insulation needs as most of my interactions were very unprofessional. Whoever is in charge here, I recommend training your "project managers" on how to manage projects and communicate professionally with your customers. read more

Our home was built in the 50s so obviously we were past due for attic insulation replacement. Communication was thorough, crew was professional, payment was easy, and great difference felt adding to the temperature comfort to the rooms. Thank you, Insulation Labs. read more

I was extremely impressed with the three person crew that came into my house. They immediately set up plastic all around the area that they will be utilizing from the front door to where my attic door was. They removed all of the old installation, sanitized and put up rodent proofing. They were amazingly quiet and efficient what they did left no dirt behind. They need to return after my electrician does the work that he needs to do in the attic so they can install the new install new and air sealing. I would recommend this crew installation labs to anyone looking to have done attic . I've already told my neighbors about how amazing they were. read more

I needed my rain gutters cleaned out. Insulation Labs (also known as Rain Gutter Labs) responded quickly, and offered the best price. The low price concerned me a little, since I had paid a lot more the last time I had the gutters cleaned. I needn't have worried. Andrew was able to schedule a time at my earliest convenience. He arrived on time, cleaned all the gutters and downspouts. He also pointed out some small wasp nests that I was glad to know about before they became a big problem. During the recent rains I had no problem with the gutters. They drained through the downspouts just as they should. So, job well done. Recommended. read more

Insulation Labs - Insulation Installation Near Me - Los Angeles, California

It's is very difficult to find good companies to work with when it comes to major house work. We needed insulation to try and help with the summer heat, so I interviewed 3 companies and Eli from Insulation Labs was the clear winner! When he came for an estimate he was on his "A" game. Now I am going to tell you I was a very cautious customer and asked for additional wording in the contract because I am always weary of companies I am not familiar with. Let me tell you, it was not necessary and they had no issue with my concerns at all! I accepted the quote,and a few days later I received a call and set up a time. Now knowing I had my concerns, they manager called me the day before and told me what they were going to do and had me come up in the attic and inspect how they would do the install. The next morning the crew arrived and they were extremely polite. I offered some coffee and then they went to work. They masked off EVERYTHING, it was as professional as it gets. The did the first run of the radient barrier and has me inspect the work and it was spot on. When they finished the radiant barrier install they had me come up again and inspect it and I tell you it was flawless! Next they blew in the installation and I ones again inspected the work and again it was amazing. Then they cleaned everything up, I paid and they went home. I am telling all who read this, it was an amazing experience! They don't cut corners, they give you exactly what is needed. I highly recommend Insulation Labs, you will not be disappointed and their pricing is spot on! Thank you to the entire team for a wonderful experience! read more

We hired insulation lab to install insulation in our attic and crawl space. They did a very good job. They were on time, and they worked very clean. They made a tunnel from the entrance door to the attic entrance so dust didn't get into our house. I went to the attic to check their work after they were done and all the batts were placed properly ensuring they are covering all the corners. I got a quote from 5 companies and insulation lab gave me the cheapest quote. I highly recommend insulation lab. read more

We had insulation labs remove our old paper insulation, clean the attic, put in R-38 batting as well as a radiant barrier. From the estimate to the installation itself this company was highly professional. They left my house remarkably clean after the install. I am very pleased with the work of Insulation Labs and would definitely recommend them. read more

I don't like leaving bad reviews but find it necessary sometimes. - cancelled appt but rescheduled for next day, not big deal really -said they would call before showing up, no call and at my door at 7am, I wasn't even dressed, originally told me between 8am-9am and done around 5pm, weren't done until 7pm. - lost power partially and they said nothing for hours, when I asked they didn't know why but got it working again. - found out later it was because they ripped through wiring carelessly in my attic. Found out bc had to have my alarm company check why it wasn't working. Alarm operator couldn't fix it bc they had also knocked the transformer out and was no where to be found. They either tossed it or insulated over it. - automated gate to driveway wasn't working when they left, found they had bent the sensor which it metal, had to get it fixed too. - now when I use my AC there is loud rattling so they clearly did something else I will have to fix. -left the light on it attic which was on for a couple weeks before I realized. I increased my rating because the manager that helped with my issues was very considerate and helpful. read more

I interviewed 5 insulation companies while building my new standalone ADU in SoCal. After careful comparison, I selected Insulation labs for multiple reasons. Their price is competitive with other vendors but it's more important to me that the sales person listened to my concerns and answered my questions satisfactorily. Their proposal came back showed that he listened and addressed my concerns. Furthermore, since my building has a crawl space, I asked them to do the subfloor insulation before the subfloor was put on. They were able to accommodate me on short notice. We did not get to the 2nd phase of insulation of ceilings & walls until nearly 2.5 months later. In the meantime, we had a change of R-value requirements. They were able to accommodate that change without jacking up the price. All the workers onsite were very professional. They cover the floor before spray foam and clean up afterwards. I'm very happy to have used Insulation labs for my build. read more

I hired Insulation Labs for a roof insulation project. The insulating has helped some for this Southern California weather. My experience: The sales rep Jacky was informative and professional. The company matched a competitors estimate. The company scheduled the service right away on a Saturday. The job: the job took 8 hours. The workers took turns with removing the old material, cleaning, sealing and installing. (Roofs are extremely hot). After the job I noticed that some light fixtures were lose. The company sent out a team right away to fix the issue. Negatives: No HEPA filter, this was a selling point for me but they did not have it. The fumes/dust from cleaning or vacuuming the materials was strong. If you go outside the vacuums that are used still produce dust. read more

Called a few places for attic insulation, most of them ignored my calls and Insulation Labs got back to me right away. Abraham came for the estimate. He recommended batting and gave me a pretty fair pricing. The day before the project, Dianna texted me to confirm the appointment . That's good customer service practice. On the day of the project, the crew came in time and were done in about 5 hours. There is a part of our attic that is not accessible to the crew. We would have to open a home somewhere else outside the house to install the insulation. I texted Abraham and asked if he can have the foreman leave behind some insulation for us to install when we have access to the closed off area. He responded to me right away and said he will take care of it. And that he did! He was always responsive, which I appreciate. The crew did a great job. They made a sealed tunnel in the hallway to prevent the dust get into the rest of the house. They left the place clean and tidy. I highly recommend them! read more

Insulation Labs - Before insulation installation - Insulation Installation Near Me - Los Angeles, California

They did a thorough job, checking out everything finding out where all the problem areas were

I was very pleased with their work! Attic looks great! We got a new roof and the old insulation was covered in debris.

Jacky Chow was our sales rep and interface who personified exemplary customer care, empathy, and did what he could to address some inconveniences that happened. We had our attic and insulation restored. Insulation Labs made sure any holes were closed up to prevent rodents from coming in and out. They did an amazing job, from the prep job of meticulously covering the hallways and rooms, to removal of old insulation, to installing new insulation, to wrapping up and finishing the job. The only inconvenience that occurred was their latching of our front door deadbolt (a good safety measure) when they left. However this prevented us from being able to come back into our house! We had to find a locksmith to get us into the house. Jacky interfaced with us and addressed our inconvenience with more credit than what we paid the locksmith. Overall very good quality work and excellent customer service! read more

Juan and his crew were all so diligent and hardworking. They did a fabulous job and were a delight to work with and have in our home. The pricing from insulation Lab was good too. It was very nice to have something go right during remediation due the chaos and destruction of the Eaton wildfire, and I truly appreciate them for that. I'm sure all the people in this area who used them feel the same way. read more

Highly recommend Insulation Labs! They are highly communicative and efficient at what they do. It was so easy to contact them on Yelp to schedule an estimate visit. Ray came for the estimate visit and was very friendly and knowledgeable. I appreciated the presentation with lots of infographics that helped me understand the entire installation process. The price was also very reasonable, with all work and service clearly itemized in our estimate. Days before scheduled installation, they would call to remind me and gave me an estimated 1-hr window of when the crew aims to arrive. Day of, Carlos and his crew arrived early! Everyone was super nice and respectful. The installation finished 3 hours earlier than projected due to the fact that they brought more crew with them. Everything was cleaned up so nicely afterwards! Thank you Insulation Labs, Ray, Carlos and the crew for such a smooth and stress-free experience!!!! read more

Your service guys left a giant duece in my master bath and didn't even have the common courtesy to flush it. I opened my hall bathroom up for them and they blew that out all day long. I specifically told them to stay out of my master bathroom. I chose Insulation labs because I was looking for a respectable business that I could trust doing work in my home. I thought I was going to get just that. Instead, I received a surprise in my toilet. Half way through the job they started to set up finishing the job on another day. I had to remind them that it was promised that the job would be finished in one day. If the guys were not sleeping in my front yard and watching their phones half the day the job would have probably been done a-lot faster. Thanks Insulation labs. I did call you about this before leaving a review. Call me back anytime. read more

Big shout out to Sagi and Angel and the whole team at Insulation labs, you guys are very professional, the communication from start to finish was excellent, the workman ship was fantastic and now my family and i are more comfortable with the new foam in our walls. thank you! Albert read more

Jacky Chow gave me a free estimate on potential insulation. I had sought this out because another place (which had inspected my ducts for a new furnace) had suggested it, but their quote was very high. Jacky was thorough and showed me the photos of my current insulation, which he said met the California code. One area had old mouse droppings, but I could vacuum it up. The insulation itself is still in good condition. I will also look for a rodent control company to keep rodents away. Overall, I saved thousands of dollars due to his honest evaluation. read more

I am a small general contractor. I am currently remodeling a house in Rancho Santa Fe so I called Cory in the San Diego area to get a quote on redoing the insulation in my attic. He was incredibly rude, and short with me. Sounds like the guy was having a bad day, but that is no excuse to speak to a potential customer in the tone he spoke to me in. I will never call Insulation Labs again nor will I recommend them to any of my colleagues or customers. read more

The cover the floor and sealed off the working area leading to the attic. See photos. Jackie Chow went to the attic to prepare the estimate, gave me a photo reprentation of what would be done. He answered all my phone call promptly. They cleaned up the attic and sealed all the recess fixtures and all the gaps. I'm happy with their service and will recommend the company to my friends and relatives. read more

Great meeting with the company representative to discuss our project. Jacky is very knowledgeable and answered all of my questions, including the pros and cons of this project. Jacky presented an excellent and very fair bid. Although we decided to go with a different company, I will definitely consider this company again for future projects. read more

I had Insulation Labs come by and repair my gutters from a tree that fell during the wind storms this January (2025). I had several proposals that insisted in replacing all the gutters with seamless, other places that wanted to use non-matching stuff, and others that were ridiculously high. The estimator from Insulation Labs listened to my needs and didn't try to upsell me or gouge me on price- this is right after the devastating fires and wind storm- and were able to fit me into their schedule. I couldn't be happier with the work done. They were prompt, on time, and thorough. I wouldn't hesitate to use or recommend them again. I'm happy to share my very positive experiences with the Yelp community. read more

Consistently outstanding from beginning to end... Last month, my parents used Insulation Labs for their home. My mother raved about them. She was impressed by her meeting with Dor (he wrote up her proposal) and by the 3 guys who performed the work. Her attic was filthy. The job took 10 hours (1 hour lunch included). She said they left the place immaculate. She couldn't be happier. Like my mom, I was also impressed by Insulation Labs. Jacky came out to my home last month to give me an quote. He gave me a video presentation that was basic, easy to follow and comprehensive. After the visit, I received a very detail proposal that was reasonable via email. I signed the document online and scheduled a day for the work to be done. Today, at 7 AM, Brandon and his crew (Pastor, Mynor and Domingo) showed up ready to work. They quickly set up the plastic tunnel from the front door to the attic entry and began the removal process. At about 1PM, I was told that the R-38 batting was already laid and they were working on the radiant barrier. A half hour later, the tunnel was down and everything was cleaned up. I was shocked at how quick and easy the process was and how minimal the mess was in between. It was like it never happened. Just before they left, I poked my head into the attic. They did an amazing job! I can't thank them enough. They were hardworking, professional, friendly and polite. Insulation Labs is also very responsive to phone calls and emails. I called and emailed Robert a few times and he quickly answered my questions / remedied the issue. Insulation Labs also helps with the DWP rebate process. They emailed my mom the before and after photos and all the documents needed to submit the rebate. If you're looking to redo your attic insulation, consider Insulation Labs. You'll be happy you did. read more

I had Insulation Labs come out to add more blown-in insulation to our attic. Our house is 22 years old. When the house was built, there was some blown-in insulation put in, but this had been trampled down in places, like where someone had to enter the attic to do electrical work. And there was never any insulation over the garage, which made it really hot in there during the summer. Insulation Labs sent out a three-man crew and a truck full of insulation. A few hours later, all that insulation was in our attic. I think the crew was very professional and did a great job. I now have a thick blanket of pink insulation on top of the old stuff. If anything, they added a thicker layer of insulation than I expected. The garage is noticeably cooler. And when I turn on the cold water at our kitchen sink, the water is definitely cooler than it used to be. In the future, I will be able to compare our utility bills to see what difference this had made. But regardless, I feel like Insulation Labs did what they were supposed to do. One thing I appreciated about Insulation Labs is that, unlike one or two other insulation companies, Insulation Labs did not try to upsell us on removing all our existing insulation and doing a bunch of un-needed work at double the price. Anyway, I am quite happy with the way it all turned out. read more

I had Insulation Labs install under floor insulation in the crawl space today. While I await installation of central air/heat, the temperature has already improved in my home.

We were very satisfied with the blown-in wall insulation project that Insulation Labs did for us. Their price was very competitive and they were very good at communicating clearly throughout the project, from proposal to completion. On the day of the installation, they were punctual, were careful to cover and protect furniture, completed the project in a professional manner, and cleaned everything up nicely at the end. They also plugged and spackled the holes where they had blown in the insulation, something that several other companies were not willing to do or would charge a considerable amount for. We would highly recommend Insulation Labs to anyone looking for a wall or attic insulation project. read more

Insulation Labs was great from start to finish. Ray came out and gave us an estimate, explained what they would do and was thoroughly professional. The work was dong six weeks later and we couldn't be more pleased. A team of five arrived and what was supposed to be a two day job got done in one long day. The cleaned the attic and removed all of the very old construction junk that was up there. Completely vaccummed all dirt so it was a very clear surface. One person was dedicated to blocking possible access points for vermin and they insulated around all recessed lighting. Then installed the new insulation. They worked as a team from the first minute to the last and left things cleaner than when they started. Even at the end of a long day, they made sure pictures were re-hung - they didn't want to take any chance the pictures would be damaged. They may not be the cheapest, but Insulation Labs exceeded all of my expectations. Do not hesitate to use them. read more

This review is long overdue. Insulation Labs completed an entire removal of old insulation, clean and rodent proofing of attic, and installation of new insulation back in September of 2023. Additionally, the team installed over 400 sq ft of plywood for storage. From the first meeting with the Project Manager Ozzy to the final clean up of by the team following their work, Insulation Labs did a great job at a great value. Compared to other quotes, Insulation Labs did more work at a reasonable price and I would highly recommend their services. read more

The process was extremely smooth from quote to work. From the day that Adam showed up to give me the quote until the day day I scheduled the insulation replacement, everyone that I talked to was very responsive and took their time to answer my questions. The day that they showed up, they set up the barriers to make sure the rest of the house is not being affected. They even did a complementary rodent proofing which I very much appreciated. During the clean up process Martin, Luis, and Moses payed special attention to the process to make sure everything was cleaned up and ready for the new insulation that they were installing. Overall very satisfied with them and highly recommend it to everyone. read more

I called Insulation Labs for a second estimate after another service on Yelp recommended removal of existing insulation (loose-fill) and replacing with batt for 5-6k. Eli and Jacky from Insulation Labs came as scheduled, fully prepared and did their walk-through of the attic. Surprisingly, their conclusion was that they recommended no work and that we had plenty of insulation. It turns out that we had loose-fill on top of batt insulation. It is always a great sign when a company values integrity and honesty to the customer over money. read more

We needed to insulate the attic of our 1940's era home, and these guys did a great job! From the first phone call contact (thanks Diane!), to the super nice and knowledgeable estimator (thanks Sagi!), to Hugo and the installation crew, the project went off without a hitch. Sagi closely inspected the attic at the time of the estimate and showed us pictures of the area and clearly explained the options and the process. He also pulled up the IRS website and explained the rebates available, and encouraged us to look into it closely because some companies twist the facts to sell the job. We did actually have another estimator who did just that, and I was thankful I had taken the time to go through the information myself. They offered some options we were not aware of, like radiant barrier, which we researched and ultimately added to the job. When we decided to accept the estimate they were able to schedule within a week. The crew arrived at 8am and they finished by 4, cleaned up the work area perfectly, you would not have known they were ever there, and then the office sent us photos of the completed work. Our house is so much warmer and the heater has hardly turned on at all. We can't wait to see the difference in summer, and are expecting our utility bills to drop significantly. We would hire them again without question! 100% recommend! read more
