Krystal Klean sanitizes and spruces up homes with its slew of window-cleaning, power-washing, and painting services. During each power-washing session, rivulets of refreshing water blast across flat surfaces such as sidewalks, driveways, and siding ($0.10/sq. ft.), obliterating mold, mildew, and Christmas lights run amok. Technicians lovingly wash windows with gentle but powerful equipment and solvents, expunging hard water and mineral deposits to leave home portholes sparkling ($5 outside; $8 inside and outside; $1 extra for screens; double for new constructions and French windows/doors). Krystal Klean also refreshes interiors and covers up Dawson’s Creek murals with its professional painting services, which imbue one room’s walls with bright new hues ($0.60–$1.30/sq. ft., depending on type of paint and number of coats).
