Siding turning green: why, and what cleans it
According to Hyannis Painting, exterior surfaces get a professional power wash to remove dirt, mildew, loose paint and contaminants, and dark spots that won't wash away mean moisture is getting into the paint film. The crew washes first, then repaints only where it is needed. Free estimates: (508) 280-1573.
