    A: Verified Devengenzo & Company Customer, 1 of 157
    "They are thoughtful, respectful and communicative. They are not just looking at the job. They will go beyond that and they will make recommendations and suggestions. To sum it up, they think like a homeowner and they see it through the homeowner's eyes. They take a very forensic look and a very thoughtful look at the whole picture. It feels like they are doing it as a friend. They are collaborative and they treat it like it is their own home. I would empty my bank account to have them come out to my house. They have compassion and care and you don't get that any more these days. It feels like a friend who is an expert in their field. They will not steer you the wrong way and they are not in it for their gain. They will do quality work and their focus is quality work and making their clients happy. When I pointed out something small that needed to be fixed, they went above and beyond to make me happy without question. They just get it and they understand what it is to do business well. I can't say enough about them. I can't stop. They take as much pride in their business and their clients as I do. Their sense of pride and respect is bar none and that is what I expect. I have a very good relationship with every person I touched and they were all respectful and courteous. I dragged them through maybe 8 estimates, as I had multiple floods with the storms and they were patient. They understood. They were human and compassionate. They get it." - Diane S.

    "I thought they did everything they said they would do and more. They put everything back in place, including one of the fence posts that went down, and they put it right back up when the process was over. I was very pleased. I thought they were well organized. Wayne originally came out, looked at the job, and about a week later the crew came out. " - Elijah L.
