Why we never power-wash at full pressure

Substrate determines pressure, not the other way around. The wrong PSI strips paint and etches concrete — invisibly at first.

Most "pressure washing" complaints we inherit come from the same source: a previous crew cleaned at tip pressure without matching the substrate.

Painted siding, vinyl, brick, stamped concrete, and sealed pavers each have a different safe window. We set pressure per surface, use soft-wash chemistry where surface integrity matters, and always test before we finish.

The tells we look for

  • Paint age and adhesion
  • Brick mortar condition
  • Concrete sealer presence
  • Any existing rust or tannin staining (different chemistry required)

The restoration comes from the method, not the machine. That's why our work lasts — and why the brick looks ten years younger without a single etched mark.
