From the start, the people from Insulation Labs were professional and offered exceptional service…read more I had five different vendors (all 5 star-rated) come to see my house crawl space to give estimates for a vapor barrier (to stop humidity and the conditions that produce mold in the house). Before estimates came in, it was clear that Insulation Labs was the best-- Ray came on time, knew what he was talking about, answered all my questions, and followed up promptly with the estimate. In addition to being the best service of all five estimates, it was also the lowest price. Julio was in touch for all things scheduling. The team that installed the crawl space vapor barrier came on time when they said they would, cleaned up all debris following the work, and left the work area as they found it. Julio called after the work was done to ask how everything was-- and I told him that the crawl space door seemed to have been bent back a bit in a way that could let a rodent slip under the house (which is understandable given how much material they had to bring into the crawl space). Julio promptly made an appointment for his team to come and fix the issue, and they even added additional hardware cloth on two other spaces upon my request. Overall, I am extremely impressed with the professionalism, service, quality of work, and responsiveness. And the price was the best of all five estimates I got as well. I recommend hiring Insulation Labs for your job.

I hired Insulation Labs to do drill-and-fill insulation, which involves drilling holes in existing…read morewalls and filling the cavities with insulation. The work included the exterior wall along my primary bedroom and children's bedroom, plus an interior wall between the garage and my children's bedroom. Both bedrooms get a lot of afternoon sun and are consistently warm. The first crew spent a full day drilling holes, adding insulation, and patching the walls. Before leaving, they told me everything had gone great. Unfortunately, photos I took with a thermal camera suggested that more than half of the areas had not been properly filled. You could even feel the temperature difference by touching the insulated sections versus the areas that appeared to have been skipped. I contacted the company, sent photos, and was told someone would come out to investigate and resolve the issue ASAP. Instead, about a week passed with little communication. Once I started following up, I felt like I was being passed around. They even sent the sales representative back out, and he said he wasn't sure why he had been sent. Eventually, project manager Julio arranged for another crew to come out the following week. When that crew arrived, they quickly realized the work was more extensive than they had been told. I wanted the affected walls redone so I could be confident the insulation was installed correctly. Julio initially told me it could be another month before they could return--even though a month had already passed since the original installation. I told him that wasn't acceptable, but that I would be flexible to help get the job completed. Shortly afterward, he called back to say there had been a cancellation and that he would send his best team. Victor and Carlos arrived the next day, and they deserve a lot of credit. After drilling additional holes, they confirmed what I had suspected: the original crew had left some wall cavities completely empty. Victor and Carlos filled the walls properly, did excellent patchwork, and thoroughly cleaned up. Their workmanship and attention to detail were far better than what I experienced with the first crew. They clearly took pride in their work, and it showed. Now that the work is complete, the insulation is making a noticeable difference. The bedrooms are cooler, and I'm seeing wall temperatures approximately 15-20 degrees lower than before. Overall, I'm happy with the final result, but getting there took far more time and follow-up than it should have. Victor and Carlos turned the experience around. I would recommend drill-and-fill insulation for exterior walls, but I would also recommend investing in an inexpensive thermal camera--I found one on Amazon for about $80--to help check the work afterward.

Insulation Labs was recommended by my HVAC company (Titan Air Conditioning, Inc.) to completely…read moreoverhaul my attic & perform an "Attic Cleanup Bundle." After discovering some of my duct connections were wrapped in asbestos, a specialized asbestos abatement company was hired to remove the asbestos & everything in contact with it. After that was completed, Insulation Labs was hired to: Remove all of the old blown-in insulation (with a giant vacuum); sanitize the attic; Air Seal any openings into the attic including any electrical wiring or fixtures (ceiling lights, attic fans & plumbing/HVAC pipes or runs). Also included was Rodent Exclusion (performed by a pest control company) - sealing up any places that allowed entrance or exit into or out of the attic. And finally, Installing R38 roll-in fiberglass insulation (cut to fit inside of the rafters). The entire crew (up to 6 or 8 individuals) were AWESOME! Especially Victor & Domingo! They were constantly giving me updates & progress reports on what was happening, & if I asked a question, they would stop what they were doing & give me their full undivided attention, completely explaining things, & then make sure my question was answered, & then inquire if I had any more questions! They were amazing & top notch individuals - representing your company with honor & distinction, & reassuring me that you were definitely the right company for the job! THANK YOU for employing such wonderful & professional people!
