Power Washing at a 2-story house in Crystal Lake on Deerhaven Drive. Completed by our Barrington team.
— Barrington crew
Crystal Lake sits far enough from the lake to miss the coastal grit, but the town's mature tree canopy creates its own problem: shaded north-facing siding that never fully dries between rains. On this two-story vinyl house, that combination had done years of quiet damage — algae working into the surface, mildew tracking down in dark streaks, and a general accumulation of biological growth that plain water pressure alone wouldn't touch.
The north side was the focus, and the condition called for a soft wash rather than straight pressure. We mixed in a surfactant and a targeted chemical solution formulated to break down the algae and mildew at the root rather than just blast the surface layer loose. The mix was applied low and slow, allowed to dwell, then rinsed thoroughly from top to bottom. Working up the full height of a two-story wall meant careful coverage in passes to make sure nothing was missed and no streaks were left behind. By the time we wrapped, the siding read the way it was meant to — the years of buildup lifted cleanly, and the north face matched the rest of the house again.

Common questions from Crystal Lake homeowners researching Power Washing.
For a 2-story house in the Crystal Lake area, power washing typically runs between $150 and $350 depending on square footage and how dirty the siding is. This particular job came in at $175, which reflected the extra chemical treatment needed to cut through heavy algae and mildew buildup on the walls.
Most 2-story house washes take our crew between 2 and 4 hours from setup to rinse. Jobs with heavy biological growth like algae or black streaks can run a bit longer because the soap and specialty chemicals need dwell time before rinsing to fully break down the contamination.
We wash all exterior siding surfaces, working top to bottom to push dirty water away from clean areas. On this job that meant treating algae-covered walls and mildew streaks across the full face of the house, applying soap and targeted cleaning agents, then rinsing everything down until the surface was clear.
We adjust pressure and chemical mix based on the siding material — vinyl, wood, and fiber cement each respond differently, and too much pressure on the wrong surface causes damage. On this house we used a controlled soft-wash approach with specialty chemicals to lift the algae and black streaks without blasting the siding.
