I should go edit my Google review. I'm very irritated and…read moreeven after days of giving myself to calm down, I'm still angry. I know for a fact that I asked if the quote and payment we gave for attic insulation, included over the garage. I was told yes, and I know I asked at least three times, and was told yes. The two other people in the home, heard it as well. The over the garage was not insulated. Now I understand, that I should have checked before I left the other review. That's on me. I shouldn't have taken anyone else's word, and I should have gotten the ladder and looked. When I texted the man who came here, I was told yes "no, it only includes over living space". The insulation over the living space is nicely done. I am very pleased with that. Just very irritated that, what I was told was going to happen, and included, turns out it's not.

The house is 30 years old and has been ours for 15; we had no idea the original old stapled-on soffit vents were so occluded and probably ineffective. John and James thoroughly explained the process to us and provided extra insulation to a troublesome corner room that's always too hot in summer and too cold in winter. They also power-washed the wooden eaves, repaired areas on trim that squirrels had chewed, and re-painted the non-brick surfaces and garage, also cleanly and efficiently. The outside temperature during the 3 days was 104 and the attic considerably hotter, but the guys soldiered on. Impressive company from start to finish!

I would understand as I am a licensed structural engineer. Before they were about to leave I had to remind them that I also paid for installing batt insulation, if I hadn't, they would have left. My request to the estimator of making sure not to add insulation over my exhaust vents were not communicated to the workers so I asked and they were not aware of this ask. They were nice and fixed the very apparent crack, but weeks later a second one formed nearby due to the worker initiated the cracking by compromising the ceiling gypsum. I did not ask for them to fix this because how I can prove it? No one has walked up there since but enough time has passed to leave doubt on how it was caused. I would not recommend them.

They also failed to pull the required permits from the city or have the required city inspection after the work was completed. The city inspection would have advised me that their work was unsafe and not code compliant. This created a very dangerous situation as the attic is adjacent to my kids' rooms and the buildup of CO2 could have been fatal. Removing the foam was absurdly expensive and I had to replace both furnaces to make it code compliant. I am taking them to court over this matter as they were not willing to pay for the repairs required to make the attic safe and code compliant.
