"This company came in a updated our 40-year old home insulation with new R-38 batting. We were impressed how much attention to detail the company has for removing old insulation, clean-up, disinfection, and installing new insulation. They also replaced a damaged dryer vent in the crawlspace. Nico and Jeremy were a great combo to work with from quote through install. I plan on calling them back in spring for another project."

"We had a problem where rats used to get in the attic via the air spaces. This big problem caused an infestation that required us to solve this problem and to replace the insulation.
Adam from Attic master, was very nice to us and understood the problem very well. He sent to our house one his main guys to check and see how he can help us solving this problem. As part of his great service, he was also able to close all the openings on top of the new insulation.
I'm very happy that 1 company could solve this problem once and for all.

"Excellent service and good people to work with! Adam was very generous to us when we contact the office and asked for their help with the problem at our house. The insulation had to be replaced based on an inspector requirements.
The replacement work took 3 days in a row and the workers did a good job. we will hire them in the future.

"I had Attic Fix Pro people take care of insulation for a new build. Their prices were very reasonable, better quote than I received from others. They advised me that the most cost-effective way for me to insulate the roof was a hybrid of Closed-cell spray and additional bats which would give me a R58+ value. It was a creative approach that would save me money and allow me to still have a very high insulation rating. Their crew came in to do closed cell spray insulation for the roof and the second time to do the bat insulation for roof and walls. They were super clean, laid down protection for plumbing, electrical, floors and walls; did their work, removed everything and cleaned up after themselves. Super happy with their work."

When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
