What our clients are saying



I got Chemwash to do a complete exterior wall and roof wash down of my house to give it a new lease of life. The service was amazing! A visit was arranged, a competitive quote was provided, and the job was completed all within very quick time. The contact that I had with the team was all very professional and courteous. The team who did the work were amazing, they went the extra mile with moving the kid’s toys, working around the dog and cleaning things that I hadn’t expected to be included. And the end result is amazing! My house now looks new – sparkling clean and it even smells clean! I have absolutely no hesitation to recommend Chemwash, and I know I will be using them again in the future.
