Mark is the owner and he is serious about getting the job done. He was always there when he said he would be. In the office is Lenore who often answers the phone immediately and if not gets back promptly- together they make a great team. Lenore is kind and professional, Mark is no- nonsense, gets the job done and gets it done right. He installed a 10 year rated roll roof product on my flat roof and gave with it a 10 year leak free guarantee - which for that type of flat roof product is great. He was in and out and not a scrap was left on the ground. In a world of shady contractors, it was a pleasure to work with a company that has integrity- I would recommend and hire them again.
