Broken drywall near recessed light
Steve O.

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.

Bot that wants your phone number. Non responsive to the request for quote. I wouldn't trust a company that want your number like that. Too bad

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!

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.

Well organized

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.

The results are that we can depend on a more stable temperature in the house with much slower temperature swings when off the HVAC. When using HVAC, it works less to keep the temps where we set them.

Their installers are delightful, helpful, and team players. A second pair of eyes are necessary during installation. Getting to the end product can feel like pulling teeth. extremely belabored. Administratively much needs to be improved. The right hand doesn't know what the left hand is doing. In my case, I had to have several repeat site visits because what I communicated did not end up on the Estimate multiple times, so on the third time I actually needed to write down every item step-by-step to hold them accountable for the bottom line, which still needed to be tweaked in the end!! That being said, I will say the team is honest!! It was discovered during install that a large portion of my job was already insulated and could not be blown-in. My estimate was changed on-site and I was billed only for what I used. EXCELLENT business acumen. That's what 67 years in business will do. I absolutely will not hesitate to recommend them, however, I will advise caution with the sales steps of this business. perhaps it's best to request everything you want in writing down to the specifics, including square footages, that way there can be no misconception of the scope of work...

From the very…read morefirst call, they were easy to get a hold of, quick to schedule, and communicated clearly every step of the way. Luis is extremely friendly, professional, and offered a great price for the amount of work involved. Luis was able to find a hidden entrance into the attic that a previous company had missed. They completed a full attic restoration and rodent-proofing on our single story, 2,000 sq ft home. The job included removing all contaminated insulation, vacuuming rodent droppings and nests, thoroughly cleaning the attic and crawlspace, sealing and rodent-proofing the entire house, and installing new batt insulation. What really set them apart was the follow-up. After the service, they checked in to make sure everything was holding up and that there were no more rodent issues. We even had a big rainstorm afterward, and all the repairs held up perfectly. Between the quality of work, the 3-year rodent control warranty, the professionalism, and the follow up, they really go above and beyond. I would absolutely recommend Natural Rodent Control to anyone dealing with rodent issues or needing attic restoration.

We were able to get our plumber out the next day to fix the leaks. Highly recommended!!
