With a referral from my insurance agent, I got the job to clean 27 awnings in a strip center. They have never been cleaned in 12 years. Lichen and algae build up was pretty heavy on about 1/3 of them, the others were light. Up early on Saturday & Sunday after a long week so we could beat the store openings. We got them done and the management company is happy. I will go back and get new after pictures when the sun is hitting the front.
