"I had my parents' roof and driveway cleaned by Chemwash a few weeks ago. We found the Chemwash team delivered first class quality work, were very efficient and attended to detail. They used modern technology for their work and we would very much recommend Chemwash to anyone who need their roof, house or driveway cleaned."
