Roof Cleaning
"My husband & I were very happy with the roof cleaning services provided by Keith from Coast Flow to both our house & barn. From start to finish, Keith was always punctual, thorough, & careful with his tasks. He was obviously very experienced & knowledgeable about his trade showing pride in his work. We wouldn't hesitate in recommending Keith to our family & friends & have already done so. Deb & Rob happy customers."
Gutter Cleaning
"Excellent service. Fully informed of availability and issues at site. Completed job same day and clean up and removal of gutter litter was excellent. I will ask Keith to keep a regular check on my guttering and to do some cleaning of the pergola roof. Highly recommended as trustworthy and efficient."
