Matched to the surface
Natural stone, interlock, timber decking and painted render each have a limit. Too much pressure on interlock strips the jointing sand and the blocks begin to move.

ServicesPressure Washing: When It Helps and When It Damages
Pressure is one tool among several, and the wrong setting causes damage that cleaning cannot undo.
Oil is absorbed, not deposited
Pressure alone spreads oil staining and drives it deeper. The method is degreaser with a dwell time, agitation, then extraction.
Drainage first and last
Channels and outlets are cleared as part of the job. Clearing a surface and leaving the drainage packed with sand means the first rain undoes the work.
Water and run-off
Confirmed before mobilising. In basements and enclosed courtyards the drainage route decides whether the job is possible at all.
Everything we do is scoped against luxury deep cleaning, priced after an inspection and fixed in writing before any work begins.
Questions
Answered plainly.
Not at the correct setting. At the wrong one, permanently.
Those are rubber transfer rather than dirt and need chemical treatment, not pressure.
Cooler months or early morning. Hot surfaces flash-dry solution before it works.
Questions this did not answer? Just ask.
An inspection, a written scope and a price that holds. We will also tell you when the job does not need us.
