Fences and shaded walls collect mould more than anything else on the property, and they're the surfaces neighbours and passers-by notice first.
What's being cleaned
Timber paling and lapped fences, Colorbond and other metal fences, rendered and painted walls, brick, and weatherboard or cladding. Each takes a different touch. Soft timber can be furred up by pressure. Painted and rendered walls need a lower setting, and water shouldn't be forced behind cladding or into gaps.
Mould, algae and tannin
The green film is algae and mould. Dark streaks on timber can be tannin or weathering and don't always come out. We'll tell you what we expect before we start, so you're not surprised by a fence that looks grey instead of new. Cleaning shows what's really underneath, including peeling paint and rot.
Cleaning before painting or staining
If you plan to repaint or stain, cleaning first is the right step, and the surface has to dry before anything goes on. Tell us the plan and we'll leave a sensible gap. The same goes for decks and other timber.
Plants and neighbours
Move pots away from the fence if you can, and let neighbours know if we'll be spraying along a shared boundary. Overspray on their side is unlikely to cause trouble, but a heads-up is polite.
Fits well with pressure cleaning and driveway and deck cleaning. Ring 02 6626 3819 or email sales@lincolnchen.net.
What to send
A photo of the fence or wall, its length or height roughly, the material, and whether it has been painted or stained. If you plan to repaint, tell us.
How long it lasts
Mould returns faster in shade and damp. A fence in full sun may stay clean for a year or more, while one under trees may need a repeat sooner. Trimming back overhanging growth helps.
