    I was very impressed how Keystone handled all the communication, worked with the adjuster and contractors and kept me in the loop. They were true to their word and responded to all my questions timely. I had my roof, gutters, downspouts, … More and garage door done through this claim working with Keystone. Glad I reached out to them instead of the random solicitors that went by my neighborhood.

    Keystone Builders reroofed our house and garage. The crew were professional and punctual. The roofing crew led by Mitch and Mike did a totally awesome job. Each member of the team preformed their tasks efficiently and with care. It was … More a pleasure working with Mitch and Mike. Mitch gave us good advise and answered all of our questions. Mike kept everything moving at a steady pace. We appreciate his attention to detail. The project was finished ahead of schedule and the yard was left neat and clean.

    We are BEYOND IMPRESSED with the Keystone Builders team and especially Jay. They were doing a siding replacement job in our neighborhood so we gave them a call to see if they could help us with a 30ft high fascia cover issue that multiple … More other companies had simply never even called us back about. Randy answered immediately. Then Jay made a same day visit to our home. He quickly and nicely offered to help us. That alone was shockingly awesome. Jay then used the siding pieces we had to do a color match and came back 48 hours later to trim the broken piece still attached to our house and install the replacement piece. I am literally sleeping better tonight knowing that part of our house is no longer exposed to all the elements because of Jay. We will gladly use Keystone Builders for our future siding needs and we highly recommend them for their quality service and work. (The house they re-sided in our neighborhood looks awesome to btw.)
