Insulated attic

The guys did a great job. They were curteous, and cleaned everything up very well when they were finished. Mark and Chris came, did their work, cleaned up and were very polite and helpful when we spoke.
My thanks again.

Attic insulation

Outstanding service!. From the inquiry call, meeting with sale rep Bill, follow up emails from Aleshia, to the day of the install by Henry and Darrell, I have had nothing but courteous and professional service from GNI. The quote was exact, no hidden fees and any questions I had were promptly answered. The work was done in a timely and efficient manner and the guys cleaned up after themselves. I highly recommend GNI!!

Very Professional

I had the ceiling insulated in my new home. Jason and C.J. from the Comber office were nice and worked very hard. Blowing-in insulation is a tough job on the best of days, but it was raining outside and it made the job even worse. These 2 got it done professionally and cleaned up every bit of insulation. If I hadn't been home, I wouldn't even know they were here. Good job.

Flexable large team to adjust to construction schedule Changes

complete reno of an old home with a new addition. Many delays and covid yet the company was flexible and adjusted to the changes.

Services completed

Batt insulation
- was an issue with application of rockwool in walls - PEX waterlines where pushed to the outside wall vs. split and installed correctly. I personally fixed it and only noticed it because I had to change the hose bibs out

Sprayfoam
- perfect job. one part of the feedback is that I wanted my baffels foamed into place which they did. However, when discussing that we would have blown in in the attic I wanted sprayfoam to go above that so paid for 24" because the rep said 22" of celeloose will be in place for R60. well it turns out its only 16" which means I paid for way more sprayfoam then needed. in the end doesn't matter but it is feedback. walls where done perfectly.

Blown in attic
- team was great did perfect work and ensured that coffered trusses where filled. They cleaned up a mess that was my fault as I forgot to tape some plastic and it pored out on our stairs. They offered to clean it up and did so. Guys where great.

All in all I recommend this company they are huge and have a lot of crews so adjustments in schedules where accommodated. Heading into winter we have a well insulated home. If I was todo it again I would only spray foam the rim joists and crevasses vs. walls. rockwool product is amazing and I would just go with that and cellulose in the attic. Would be cheaper too.

Very Professional

We just replaced our roof and knew there was a leak so we thought it would be a good idea to have it checked. We were given the price with removal which is what I wanted.
Phil and Brandon came and sucked it all away! Good job boys!
Phil and Nathan came after the weekend and filled the attic with the correct amount of insulation. Gotta get used to being warm!
