What Our Customers Are Saying
Last year a hail storm came through and created damages to our roof. In May 2025 we started working with Keystone Home Services (specifically with Tyler, Juan, and Carlo's Team) on how to file a claim, and set up a date to get our roof replaced. From the time of the inspection to getting the roof done, we received great communication, professionalism, and work from Keystone Builders. The team arrived as expected and got straight to work with no delay. We definitely recommend Keystone Home Services to anyone looking to get their roof replaced!
Yee Thao
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, 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.
Lissa Flaaten
Keystone Home Services did amazing work on our home! New house roof, siding, gutters, windows, doors, and our shop roof. The crews were professional and respectful. They showed up on time and did an amazing job! Their clean up was great. There was a very minor issue with excess caulking on one door and Jared, the salesperson was on top of it and had it fixed and looking beautiful immediately. Very happy and would recommend them to anyone!
