The insulation in my crawlspace under the house was consistently wet and after getting plumber to…read morecome 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

Restrictions based on house layout not communicated well.

Since Jonathan and Ralph already had their equipment on-site, they offered him an amazing price too and got his house done the same day--two houses in one shot!

Having a group of workers in your attic can be nerve-racking, but these guys were professional, respectful, and great to work with from start to finish. My attic was in terrible shape--old 60-year-old insulation, trash, nails, wood chips, and even a nasty rodent odor. The team completely cleaned everything out and thoroughly sanitized the entire space. They truly went the extra mile by sealing every opening with foam and wire mesh to help prevent any future rodent issues. The new R-38 batt insulation was installed cleanly and correctly, and you can tell they take pride in their work. I originally chose 911 Attic because their pricing was competitive and their Yelp reviews were excellent--and they absolutely lived up to those reviews. I highly recommend 911 Attic for any attic cleaning or insulation work. Great work, great crew, and great experience overall!

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...
