Positive
“I am a contractor and am very aware that some contractors look to take advantage of those who have no knowledge in the construction field and look to take advantage of the people especially the women of the house. That being said, I was not home during the time Jose came to provide the service. I was surprised to find that he kept me in the loop via pictures and video. We had had another company come the day …”
“These guys are great, no b.s. Jose was honest and right to the point. Work was fantastic and we are as snug as a bug in a rug. Barry”
