Surface-Specific Pressure Washing in DFW
The most common exterior cleaning mistake in the DFW market is applying the same pressure washing approach to every surface. Concrete driveways and sidewalks can tolerate 2,500–3,500 PSI at the surface with appropriate detergent — this is necessary to effectively remove embedded grime and oil stains. However, applying this same pressure to brick mortar, limestone, stucco, or wood causes permanent damage: mortar erosion, stone surface etching, stucco delamination, and wood fiber damage.
Here are the correct approaches for DFW's common exterior surface types: Standard concrete (driveways, walkways, pool decks): 2,000–3,500 PSI with appropriate standoff distance and tip; Brick and masonry: soft washing at under 500 PSI surface pressure; Limestone facades and hardscape: soft washing with pH-neutral chemistry; Stucco: soft washing at under 400 PSI surface pressure; Wood siding and decking: 500–1,000 PSI with wood-safe chemistry; Pavers: 1,500–2,500 PSI followed by joint sand restoration; Metal surfaces: 1,000–1,500 PSI with appropriate chemistry.
