Power Washing
Using high-pressure water spray to clean exterior surfaces before painting or to remove dirt, mold, and debris.
Why It Matters for Homeowners
Why it matters: power washing is the standard prep step for any exterior repaint, but the pressure has to match the surface. Too much pressure on old wood lifts the grain, on stucco it can drive water behind the finish coat, and on lap siding it can force water under the laps where it sits and rots the sheathing. Drying time after washing is non-negotiable, usually 24-48 hours minimum before priming.
