Review by a customerin Wilmington, DE Project: Install Concrete Patios, Walks and Steps
Mark did a great job on the concrete patio. He was easy to work with also. After finishing the concrete he didn't do the great job of making the adjacent grass tie into the patio area. You could stilll see the base at some areas.

Review by Arthur P.in Wilmington, DE Project: Repair or Resurface Concrete Driveways, Patios, Walks & Floors
Mark Weldon did excellent work. He was always on time, produced high quality work on time and for a fair and reasonable price. He also cleaned up the work area very well after he completed the job. I would recommend him highly to anyone who had similar concrete work to be done.

Review by Kevin M.in Wilmington, DE Project: Install Concrete Patios, Walks and Steps
Mark was very friendly and professional. As soon as we committed to the project he was there the next day starting the job, and was finished the day after - very quick and beautiful job! He even replaced a flower they accidentally stepped on.
