"It's hard to know about the quality of the work since I wasn't up in the attic with him. Would have been nice to have before and after pictures so I could see the amount of new insulation blown in. I just have to take Jasons' word for it. His cost was about 30% lower than the competition I got bids from. Overall satisfied."

In addition they installed insulation in my garage to r45. Very hard workers and very professional. I would highly recommend them for anyone else looking for insulation. Leslie Jones and this is my"

Customers say: Quick response

"Since we had squirrel damage on some electrical wiring in the attic, we hired them to first remove the old insulation so the electrician could more easily do the wiring repair. Cost more to remove the old stuff (old and worthless), but it saved $500 on the electrical work bill. After the electrical work was done, they came back and filled in the attic with R49. The guys doing the the removal and installation work were great, and it went quickly and efficiently. Terry was a good guy to work with for estimates and scheduling, and Brian for invoicing. Overall, we are very happy. Wish that work with all home contractors went this well."

"The work was done in a manner that was clean, specifically taping the plastic temp walls to prevent the insulation particles from spreading throughout the house. The top of walls were sealed, baffles placed, access hatch framing was raised and 18? of insulation was blown to achieve an R-60 rating that we wanted. Cleanup was quick and thorough. Highly recommended Giovanni and his team!"

"Ralph Bertrand from Home Genius Exteriors came out to thoroughly examine our roof. Ralph showed us many photos & a video of our roof, outside & inside. Ralph took the time to answer any questions we had. He explained the various products used & levels of warranty available. We really appreciated the time Ralph spent explaining everything to us, all without pressure to buy. The day of install arrived & the team was on time & ready to work! One thing we liked was that there was someone there from Home Genius Exteriors during the whole time of install. Richard Bowan, the Install Manager, was there to oversee everything & he did an amazing job. They placed large tarps over all our landscaping & got right to work. Rich kept us updated on progress throughout the day & answered any questions we had. In addition to the new roof, we also had new gutters with leaf guards & downspouts installed. When the work was completed, we walked around the house with Rich. Everything was completely cleaned up; there was nothing left behind or out of place. Our home looks amazing. The new roof, gutters & downspouts really look beautiful. We loved our experience with Home Genius Exteriors, especially working with both Ralph & Rich. They were so professional & knowledgeable. We would recommend them to others & if we needed additional work, we would definitely call Home Genius Exteriors."
