House washing in Pymble
Exterior cleaning in Pymble usually starts with the roof and gutters. Terracotta tiles on interwar houses grow moss and lichen on the southern pitch under tree cover, gutters fill with leaves and bark from eucalypts and turpentines, and valleys silt up until water backs under the tiles. Lower down, roughcast render and face brick collect green film on the shaded side, paths and steps turn slippery, and the solar array on the sunny pitch dulls beneath pollen and bird mess. Houses near the highway add road grime to the list. A house wash, gutter clean and roof treatment are often booked together so the ladder work happens once.
A vetted tradie treats an old Pymble house gently: soft washing with a biocide for render and painted timber, low pressure on sandstone and brick, and no high pressure on terracotta that could strip the surface or drive water under the laps. Wash water is kept off the street and out of stormwater pits, which NSW pollution law requires, and is directed onto lawn or garden instead. Anyone on a two-storey roof uses fall protection under the WHS Regulation, or cleans gutters with poles and cameras from the ground. If eaves or a shed look like pre-1990 asbestos cement, the tradie stops and tells you rather than washing it.
To get matched, describe the house in the quote form: single or double storey, roof type, whether gutters, roof, solar panels or just the walls need attention, and any heritage conservation area you know of. Vetted, independent tradies with Pymble houses already on their books receive it; they get in touch, usually ask for photos or a quick look, and quote directly in writing. The written quote ought to spell out the technique for every surface, the plan for run-off, and anything left out. There is no cost to homeowners and no obligation to proceed with any quote.

Frequently asked questions
Yes, with a low-pressure treatment rather than blasting. The biocide kills moss and lichen, which then weathers off over months. High pressure on old terracotta risks surface damage and water under the tiles, so a careful tradie avoids it.
Some will. Under tall eucalypts, gutter cleaning in autumn and again before summer storms is common, and gutter guard lengthens the interval. Ask the tradie what interval suits your tree cover.
Routine cleaning is not normally an alteration, but anything that changes the appearance of the building, such as repainting, may be. Check with Ku-ring-gai Council. Low-pressure methods protect the original fabric either way.
The tradie plans where water will run before starting, uses drain covers or bunding at the lowest point and directs run-off onto lawn and beds rather than into the gutter or stormwater pit.
