KCSI's John Knowlan and his team did a great job repairing a couple of rafters (broken by a tree that fell on the house), then replacing the entire roof with architectural shingles and installing new gutters and downspouts. They even replaced a few window screens that had been damaged by the tree, at no extra charge. All in all, an excellent job done on time and on budget, and I highly recommend this company for any roof work.

Very happy we chose KCSI for our roof, siding and windows replacement. Mike and his team were professional, always on time and explained everything in as much detail as I needed. I highly recommended KCSI. They’re down do earth, no pressure selling or gauging for ‘extras’ like others we received quotes from. Our house looks amazing.

John and his crew, at KCSI, do excellent work. During our home inspection, the inspector noticed our roof leaking through the attic. I called KCSI and they were able to come out and fix the leak for a good price. Not only that, but he noticed my vent cover was missing and fixed it while he was there. He had photos to show me of before/after the work was performed and we were extremely pleased with this experience.

KCSI recently removed old siding and installed vinyl siding on my house in Burke. I am extremely pleased with the work done. Not only was the work done in only 2 days time, the work was done by a seasoned crew of 5 who worked seamlessly and did excellent work reflecting work experience of over 15 years with KCSI. John Knowlan of KCSI was knowledgeable and cordial to deal with and made the overall experience so pleasant. I highly recommend KCSI. Walter W.

I was worried I needed a new roof. Another contracter patched my roof several times and it continued to leak. KCSI came out and offered a solution the other contractor never mentioned. John Knowlan stayed in constant communication with me. He sent pictures of the problem area before the repair. His estimate was extremely fair. He also sent pictures after the repair. Even with how busy roofers are right now (after a month of rain), they were able to repair my roof within a week of inspecting it. I will always go with KCSI from now on!
