Christine V.

He was knowledgeable about the material, shaping the railing to let water roll off and how to create the ovals that I wanted in the design. He was very professional and prepared when we met. He was responsive over email and text. He was too busy to start the job in May but we are thinking of hiring him when he can schedule us.

Guy B.

The price that he quoted me does not include the demolition. He was going to do the rebuilding. He was prompt. He was there when he said he would be; he is reliable. He seems knowledgeable on what he is doing; that is the reason why I went with him. He even had to drive at least forty miles to get to me. He is very available, and he is very professional.

Klaus & Maxine F.

He gave me a fabulous deal. We had a little shed roof over some concrete steps but I wanted to make a wider stoop leading to the portico with blue stone and brick with two side walls to accommodate our wide double doors. These workers always came a few minutes before their scheduled start time, sat in the drive and waited until the appointed start time and then began work at 7:30 promptly.
