We do not strip paint with pressure washing — a limit that matters as much on aluminium siding as on old wood, for different reasons.

## What happens when you pressure-wash aluminium siding?

Two things, and neither is obvious at the time.

The first is denting. Aluminium siding is thin, and a concentrated jet at close range will deform it, particularly on the wide flat panels used through the 1960s and 70s — which is a great deal of what covers Plainville's post-war housing. The dents show as ripples in raking light and cannot be undone.

The second is chalk. Aged aluminium develops a powdery oxidised layer, and washing it hard removes some of that chalk while leaving the rest. The result is a surface that looks clean but is inconsistently prepared, which is a poor foundation for paint. Aluminium wants washing at moderate pressure with the right detergent, then proper priming — not brute force.

On the town's older wood the reasoning is different but the conclusion is identical. High pressure drives water behind laps, raises the grain on softwood, and takes material off sawn and pierced detail like the Campground cottages carry. So washing is a cleaning step ahead of a coating step, at whatever pressure the substrate can take.

We do not perform mold or fungi testing, abatement, remediation or air sampling.
