"Paul and his crew were amazing.  I haven't seen three guys work that hard and that efficiently in a really long time.  In addition to busting their humps, knocking out all of that work in the short weather-window they had, they were very professional and friendly too.  They really took pains to make sure I was satisfied ... nay... elated... with the work.  I wish everyone I contract with for work were half-as-good as Paul and his crew.



I was also pleasantly surprised with the quality of the windows they installed.  I hadn't really given it much thought, and just assumed they would be cheapo windows, since that is what we have come to expect as the baseline default.  They are actually well built, and come with a great warranty too.



If you want the job done right, this is the company to do it.  I was extremely impressed.

"We had a 35 year old solarium in great need of repair. The project was complex and difficult, but Wayne had the skills and expertise to replace six large windows and rebuild the solarium. It was a challenging project, and Wayne did an exceptional job. Our "new" solarium adds greatly to the value of our house. Wayne knows windows and doors and he gets five stars from us! Mary Ross"

"The project was a mid-size to bigger size project that included removing parts of the old siding, soffits, fascia boards, gutters and downspouts and window shutters. The siding was replaced with James Hardie siding with a combination of lap siding and shingles and custom window trim. Shutters were replaced with cedar shutters and all gutters were replaced with seamless gutters. Overall the work completed was top notch . We did have a minor issue with the window trim, but that was fixed to what we were good with and they gave us credit on the final payment for the issue. The GS crew was great to work with, very friendly and very responsive. I would definitely hire them again."

"Martin is an A class worker, competent, detail oriented, timely and neat. He did excellent work repairing the rotted fascia boards on my roof in 95° weather and even did more than I was expecting. You can't go wrong with Martin."
