I hired Steve and his group to perform two jobs: steam spraying/oil stain removal on my very large driveway, and steam cleaning/mildew removal on my asphalt shingle front roof. He was extremely professional and dedicated to the highest standards. My roof looks brand new and the driveway, twenty years old, looks impeccable. Furthermore, though I had a scheduled appointment for the roof job, my home is on the market and I was asked for a showing without much notice. On a Saturday morning, Steve jumped to my rescue, knowing I wanted to have the roof looking pristine. While he was here, he spent more time working on a couple of driveway spots that needed a bit more attention. Overall, you cannot find anyone better in quality and customer satisfaction than Steve and Green Boys.
