Power Washing in Winnetka, IL

Wood siding on an older Winnetka house tells a story about itself the moment you walk up — this one had algae working into the grain along the walls, and a season's worth of grime sitting on top of that. The front porch alone showed the kind of buildup that accumulates when a house has been standing long enough to develop its own microclimate in the shade. At 2,908 square feet of surface area, it was a full day's commitment, and the landscaping surrounding the foundation — established plantings close to the walls — meant we'd need to move carefully from the start.

We pre-wetted the beds and kept them saturated throughout the wash to protect the roots from any runoff. The algae required a soap application and dwell time before we could move the surface with pressure, so we worked in sections, letting the solution do its part before rinsing. On wood siding, controlling the angle and distance matters — too aggressive and you raise the grain or drive water into seams — so the pace was deliberate. The porch received its own focused pass. By the end of the day, 2,908 square feet of siding had been cleaned down to where the wood could actually breathe again, and the invoice went out the same afternoon.
