Needed chimney flashing and chimney sealing for leak into my attic. Crazy high price but they were available and I needed work done asap. After three years, I have same leak and pieces of chimney on my roof. When you call the listed number on web site (at same 31 Nicole Way address in Mahopac) only get answering machine that says I've called Keystone Maintenance. When I called the number listed on my original job estimate, it goes to the the voicemail of a young boy, not a business.
STAY AWAY FROM THESE GUYS.

Frank came to sweep our chimney. He was thorough and kept everything clean. Part of his inspection he found damage to our chimney going to our furnace. He provided us with options. Frank corrected the problem and again cleaned up after himself. I would hire him again without a second thought. Thank you Frank.
