I have never met Mark and does not know what he looks like. I asked him to go to my property and gave me an estimate. He did promptly. The estimate is very reasonable. He is responsible and responsive licensed, bonded contractor. I checked. He did the job without asking for any down payment. He is trust worthy as well as trusting. Most contractors I dealt with asked for money first, as those all they worry is whether money part of the transaction. He did not make me sign anything nor be present, nor running around. He took care of my missing gutter just by few phone calls. I will know if the installing is good when raining season comes, but the experience was good. Most contractors worry about money part of it. Mark just want to do a good job. Nice.
