Mark and his crew are excellent. He does great work for a decent price, arrived on time and cleaned everything up when the project was completed.

He got the job done, was on-time, and price was reasonable -- can't really ask for much more.

Mark is a very professional and nice man. As soon as I located him on HomeAdvisor he called me right away, and we discussed the work I needed done. He came to my house 2 days later and gave me an estimate. I needed part of my concrete patio and steps replaced. He started work immediately. He was finished the job in 2 days. My patio and steps look amazing. It rained last night, and he came by this morning to cover the work he had done. I cannot say enough good things about him, but one thing did surprise me: HE did most of the work himself with one other worker helping him. He's a hard worker and takes pride in the completion of the job. His attention to detail is incredible. I will be hiring him again for repairs to our walkway. I will be recommending him to other people who inquire about concrete repair.

Mark was personable, honest and fair, very concerned with his quality of work. Steadily working through entire project, replacing sidewalk and adding steps. I was very pleased with the work and would highly recommend Keystone.

From start to finish, Mark Weldon was a pleasure to work with. I had Mark tear out and replace a section of a concrete sidewalk that had a long crack in it. He did an excellent job and I will definitely hire him for more work in the future.

The company was efficient when repairing the chimney cap. Took pictures to show what was repaired since we could not see.

Very fast work & good quality. The quote was a little more expensive than other companies, but on the other hand they started much faster. Just watch out for price increases after they've already started. Raised the price on me when I no longer had any real option to change, never let me know that this price increase could be a possibility especially since we'd talked about the specific issue before the quote. Other than that, they were fine and did good work.
