Get matched with top insulation pros in Wittmann, AZ

"Koala replied to me quickly. I had 3 quotes, Koala provided the insulation I needed at a good price, but beyond that, the customer service from the quote to the work was great. It was seemless and all done with kindness, willing to take time to explain and answer questions. Prompt, in fact I made my decision on a Friday with a Monday completion. THANK YOU"

"The job was completed nicely and they replaced the original insulation in my home from the 60s."

Kasi is a local, family-owned and operated spray foam insulation contractor. We service Phoenix, Tucson, Prescott, and northern Arizona. Two brothers, Patrick and Paul Kariniemi, founded Kasi in 2010. Prior to starting Kasi, Patrick spent ten years with a spray foam roofing company in Phoenix and Paul was an industrial construction contractor in Minnesota. Although we’ve tested nearly every foam insulation product available in Arizona, we’ve only purchased foam from a few suppliers. We have an 11-year long relationship with our injected foam manufacturer and a five year long relationship with our spray foam supplier. Since each foam insulation product has its own application characteristics, we’ve found that you have a lot fewer problems by sticking with reputable manufacturers who stand behind their products. As a result, our technicians are experts in the products they install.\n\n

"Thermal Advantage did a great job insulating the masonry walls on my home. His crew was on time, answered all my questions, and now the difference in room temperature is noticeable. Well worth the reasonable price as I am seeing savings on my utility bill."

"So far we only had the energy survey and report (sales pitch). The technician and sales rep were courteous and provided answers to our questions. Neither were pushy. We are doing comparatives on the cost of adding insulation to the attic and sealing leaking vent, ducts and returns. We told them we were not interested in Solar and they did not force the issue. They did suggest we do the outlets and door molding ourselves."

"I am quite pleased. Sukh, the contractor, was very courteous, professional and prompt with estimates, and returning phone calls. His work crew was very skilled and neat. They showed up on time and finished very promptly. We will be sure to call them again."

"I called to set up a free consultation and was promptly met at the agreed upon time. We discussed my desires and how to achieve my project goals. I was given a quote and agreed upon the price for the garage work to be done the following week when I was free. The spray foam and "drill and fill" have been awesome! I have a 24K BTU AC unit in the garage that was unable to keep the temps low as there was so much heat in the garage all day. After the insulation was done it can hold the temps at 70F in the garage while barely turning on during the day. The attic above the garage tops out at 85F when it was over 110F outside, just amazing. We had them do a home energy audit and found that there were plenty of leaky areas in the attic and the insulation was 15 years old and about an R-10 level. It needed some serious work so we agreed to have it topped off with new fiberglass insulation. The guys came out and did and amazing job bringing me up to R-39 as well as keeping the house very clean while doing it. On both days they cleaned up after themselves and took great care of my house. I would wholeheartedly recommend them to anyone that could use more insulation!"

"Very professional. On time. Good communication"

"Oscar was very professional and did things in a timely manner. He got the job done only a couple days after the estimate which was the best part because with the summer heat approaching we wanted the job done sooner than later."

"The installers showed up on time, were very courteous, completed the job within a few hours, cleaned up and were gone. They did an very good job of installing the insulation and now I can't wait to see my bills go down. The cost of the project was a little more than I wanted to spend but I see it was worth it. It was something I couldn't do myself. I would recommend."
