I called Mike at GBS to ask for advice regarding a roofing issue I was having and not only did he tell me exactly what I needed to do, he assured me that even though it was a small job, they would take care of it. Needless to say, I have hired GBS for my next big job! Thank you so much!

I contacted GBS to replace an old tar and gravel roof with a torch on roof on my 3,000 square foot commercial building in downtown Huntsville. Greg Antoine was the supervisor of the work crew and I was very happy with both him and the crew. Greg answered all my questions and made sure the job was completed to my satisfaction.

Straight garbage. Didn't call me back last year for the eavestrough quote I wanted. Didn't call me at all this year for the siding quote. Also didn't stick to the quote I was given to re-shingle my roof. This is who the Home depot gets for their installs.

I was made to feel like I was in good hands and could trust them when a reno was done for me in 2015. Feel like a fool now, because I've since had to have the roof they did removed and completely replaced at my own expense after it leaked profusely and incessantly causing extensive damage. On top of that they didn't finish the rest of the job and I'm STILL paying to do things they were supposed to do, but didn't do, and re-doing things that they didn't do properly. I was also told that all inspections had been done, when they hadn't. They took my money in expert fashion tho!

Jim & Kathie - Barrie We arranged through Home Depot and GBS Contracting for a new eavestrough & gutter system before winter hit. As soon as there was a break in the weather Craig and Brad were here installing. They were very friendly and professional and had some very useful ideas to improve the drainage system. The installation was completed very quickly - cleanup was amazing. We're happy
