Keystone Siding Corporation describes itself on its BBB listing as offering installation of energy efficient siding, vinyl and wood windows, sunrooms, porch enclosures and doors. Its Angi profile says it has been helping homeowners since 1988. In a recent Google review, a customer who was recommended to Keystone by a friend says the company finished a siding project they had been trying to get another local contractor to fix for over 10 months; Bill fit them into his schedule, finished the siding very quickly and communicated well. In a 2020 review, a customer who hired Keystone for vinyl siding repair wrote that Bill was on time, showed them what needed to be done, made a recommended change they went with, completed the work promptly and cleaned up before leaving. In a 2012 review, a customer wrote that Keystone replaced their roof and did a great job on the roof and the clean up after. In another 2012 review, a customer wrote that the workmen showed up on a timely basis, put up extras such as lights front and back and a flag attachment, and picked up the yard at the end of each day, and that the owners introduced themselves and called regularly to check for problems. Keystone carries a B- grade from the Better Business Bureau, which lists 1 complaint on file.

I am so happy Keystone Siding was recommended to me by a friend. Bill was fantastic, and I appreciated his knowledge and recommendations for our project. The siding on my house looks great. I appreciate that they came to our rescue and finished a project we had been trying to get another local contractor to fix for over 10 months. Bill fit us into his schedule and finished the siding for us very quickly. Communication was also excellent. The work looks great and I wish I had asked for a recommendation sooner and will definitely reach out again for projects in the future.
Contacted Keystone to do some vinyl siding repair. The communication was great. Bill was on time, showed me what needed to be done. He also made a recommended change, which I ended up going with. Work was completed promptly, and I was happy with the end results. Bill then cleaned up before leaving. I would contact Keystone again for future jobs.
Keystone replaced my roof. They were professional, courteous and incredibly neat! Did a great job on the roof and the clean up after! I will look to them when I am ready to tackle the siding on my home.
The workmen showed up on timely basis. I received exactely what I ordered & they so nice about putting up all the extras I had such as the lights front & back, the flag attachment, etc. The yard was always picked up at end of day. The owners of the Company both introduced themselves & were very professional & called on a regular basis checking to see if there were any problems. I would be more than happy to recommend Keystone .
