"Quick and easy and left me with the good wall anchors if I needed them"

"Very happy and pleased with the entire experience. He was very nice, offered really nice recommendations that would accommodate the house. Took the time to explain to me why he used the materials that he did. Just overall, a very pleasant experience, and I would definitely recommend."

"We did a total remodel of our bathroom. It turned out great! The workers did everything we asked (and even changed a couple of things my husband didn't like). I took off a half star because I didn't always get a fast reply to emails. The cost was very reasonable and I would use them again."
