As a long time home owner, I've hired many contractors in the past. And being an small residential electrical contractor myself, I somewhat know the home reno business, and I pride myself on having a high customer satisfaction rating.
Before hiring NERR, I asked for references and Scott provided several. I called them to get their opinions, and they all gave very positive reviews. Being the skeptic that I am, and knowing that there are negative reviews on this very forum, I challenged Scott about them. He didn't brush them off, but he confidently explained at length how he stands by his work, and even asked me to go look at several sites that he renovated. It convinced me to give him a shot.
Now, I have dealt with (been burned by) contractors long enough to expect less than what they tell me that they are going to provide. There is always an excuse, always a misunderstanding of what was agreed to, always an attempt to explain away shoddy work that I have to press, beg, or threaten legal action to fix.
But there was none of this with Scott. He replaced my roof, siding, soffits, downspouts, trim, basically all exterior except the bricks, doors, and windows with quality and care (my house has bricks for the first level, siding for the second). He arrived when he said he would. He then carried out the entire scope of work that we agreed to. It took him longer than he expected, and he didn't complained about that even once, or try to blame me or others (which I am used to contractors trying to do!).
Scott is a straight up honest guy, and he loves what he does! He enjoys standing back and looking at the result as much as the home owner does! One caution though... if you try calling his cell mid-day, don't be alarmed if he doesn't answer. Why? Because he is on a ladder or roof, working with his crew, actually directing and carrying out the work! Don't worry, he'll get back to you later or at the end of the day when he isn't on the tools.
Do I recommend NERR? NERR is the ONLY contractor I would recommend for home exterior work.
