House Washing
Low-pressure soft washing lifts algae, mildew, and grime from siding without forcing water behind it.
Harborline restores siding, roofs, driveways, and decks with the right pressure for every surface — and the steady, insured crews to do it properly.
From delicate soft washing to heavy concrete restoration, every surface gets the method it was built for — never a one-size-fits-all blast.

Low-pressure soft washing lifts algae, mildew, and grime from siding without forcing water behind it.

Gentle treatment clears black streaks and moss, extending the life of shingles and tile.

Surface-cleaner passes remove oil, rust, and years of buildup for an even, stripe-free finish.

Careful cleaning revives wood, composite, and stone, ready for sealing or a fresh season outdoors.

Interiors flushed clear and exteriors scrubbed of the black tiger-striping oxidation leaves behind.

Storefronts, walkways, and dumpster pads kept presentable on a schedule that suits your business.

Not when it's done correctly. Delicate surfaces like siding and shingles are cleaned with low-pressure "soft washing" and specialised detergents — the pressure is reserved for hard surfaces like concrete.
Most homes benefit from a house wash every 1–2 years, and roofs every 2–3. Shaded or tree-heavy properties may need it a little more often. We'll give you an honest recommendation.
Usually not. As long as we have access to the areas being cleaned and an outdoor water spigot, most jobs can be completed while you're out. We'll confirm the details when we schedule.
Yes. We pre-wet and rinse landscaping around the work area, and our biodegradable solutions break down safely. Pets are best kept indoors while we work.
We do a final walkthrough with you and won't consider the job finished until you're satisfied. If something was missed, we come back and make it right — that's the guarantee.
Tell us a little about your property and we'll get back to you the same business day with a firm, written price.
