    I can not recommend them enough. Not only did they do an absolutely amazing job from start to finish, the price to do the whole job was amazing. The drop in the temperature in my house was immediately felt. There are three bedrooms in my house that would be hot to the touch especially in the summer. Insulation Labs removed and replaced the insulation in the attic along with insulation blown into the exterior walls. Those exterior walls are now cool to the touch even on the hottest days. The team came in and did a wonderful job masking off all the areas of the house to keep as little dust as possible from going into other parts of the house. They covered all the floors to protect them from getting scratched. In one day the job was done. I am so happy with their work. Just look at our before and after pictures. It speaks for itself.

    Attic insulation that was removed

    I was in need of an attic re-insulation and contacted Insulation Labs after reading many of their great reviews. I had them come out and provide various quotes for what needed to be done. All the quotes were resonable and after settling on a scope of work we agreed on a date. Juan and his crew showed up at 7am sharp and worked tirelessly throughout the day until 6pm that evening. They removed bag after bag of the 1800sq ft attic insulation before installing an extra thick batt insulation that we had agreed on. We're very happy with the work Juan and his crew did and with the overall experience with Insulation Labs. Good value, quality work. I highly recommend.

    Insulated to specs.

    We were reluctant to replace the insulation on our 40 year old house and found it hard to justify spending a big chunk of money as we already had insulation in our attic and it appears to be working. After having a termite inspection, we were notified that there were pest issues and it was advisable to clean a very messy situation upstairs. We brought in at least 1/2 dozen attic contractors and got a wide range of bids. The high bid was 2X the low bid; each claiming to perform essentially the same service. After checking their reviews and google mapping their office, we narrowed it down to Insulation Labs. Many of the contractors were highly rated but Insulation Labs struck me as being the most detailed and professional of the entire group. Their quote was also quite competitive (neither the lowest or most expensive). On the day of the job, they arrived on time equipped with everything to perform the job. They totally enclosed the work area. Meticulously removed the old insulation, cleaned, sanitized the attic and replaced the insulation to exacting specifications. After the job was completed, everything was perfect. The house is quieter, the air smells better and the air conditioner only runs for a few minutes (We upgraded to R38). Highly recommended.

    I had a great experience woth Angel the project manager and Adam whom gave me an estimate. They were very professional and knew what they were doing. I truly hope they get a chance to train the backend office, there was a miscommunication that caused necto restructure my workday but Angel corrected it at the end. Im happy with the prepwork,cleanup,and installation. My house is so much warmer now :)

    The crew showed up on time, and very courteous. Work done right, clean, and professional. Dust tunnel were enacted to keep dusts and pollutants out. After work is done, the work area is cleaned. Gaps on the attic were properly sealed. Price is reasonable as well. Highly recommended.

    Insulation Labs did a wonderful job installing batt insulation in my attic space. My attic space has low clearance and other companies recommended me to install loose fill. They also screened all my crawl space and attic Insulation labs did the entire work in one day! they protected the walls and very courteous.

We had contacted a local company and, while the quote and scope seemed adequate, the plan for condenser placement was not great and I had sticker shock. So I went to YELP and found JL Martin. I am so glad I did! Jared toured the home, and came up with a great plan for a new system and was able to come in around 3K less that the previous company. I appreciated the 'out of box' thinking! This included working with the city permit process as well. The biggest hold up was actually the city acknowledging and passing the plan. Once that happened the JL Martin team scheduled quickly and the install was completed in under a day. The install team was incredibly respectful, explained everything that they were doing, and took great pains to be as unobtrusive as possible. They gave me the guidance on what to expect with the state inspection and city, made sure I understood what the filter requirements would be in the future and the city signed off within 10 days of install. I could not have asked for a better experience! They really work with you and everyone, from installer to office staff to upper management were amazing, responsive and helpful. They deserve all the reviews that encouraged me to reach out to them.

There was so much debris in my attic afterwards that it looked like a dump. I called Attic Advisor and Nick came out to give me an estimate. He told me exactly what they would do and showed me photos of previous jobs they had done that looked similar to my situation. I was so impressed with Nick's explanation and professionalism that I decided to have Attic Advisor do the work. On the appointed day, the crew arrived right on time and got right to work. They put up plastic to protect my walls and laid down plastic on my stairs to protect my carpet. They actually created a plastic lined tunnel where they could take the debris straight out to their truck without it blowing all over my home. I had fiberglass batting and blown-in insulation that they removed. They vacuumed out the attic thoroughly. I was provided with photos taken before, during, and after the project was completed. The old insulation was removed, all holes and cracks in the floor and walls were sealed up, they used a fogger to remove any contaminants, and then they installed new fiberglass insulation. My attic looks great!. Nick was very patient and kind throughout the process from start to finish. He explained everything clearly and answered all of my questions. I feel so much better knowing that my attic is now spotless and sanitary. I highly recommend Nick and Attic Advisor!
