Render cleaning in Rainham and Purfleet. Algae, green and black streaks removed from silicone and painted render with a biocide wash, not a harsh pressure washer.
Render on the north side of Rainham houses, or under trees, often turns green or black within a few years. It is algae and dirt rather than damage, and it can usually be cleaned without harming the finish. High-pressure washing is the wrong tool: it can strip texture and force water in. A biocide wash kills the growth, a soft clean removes it, and a treatment slows it coming back.
In Rainham, the cost of cleaning render depends on the wall area, access to the upper floors and how much growth there is. A single north-facing wall is quick; a whole house takes longer. Photos of each wall are enough to price it.
The damp air off the marshes around Rainham and Purfleet is a big reason render goes green here faster than in drier areas. A clean every few years, rather than waiting until the whole wall is dark, keeps the job small and the cost down.
Applied to kill algae and lichen at the root rather than just blasting the surface.
Low-pressure rinse that removes growth without damaging the render texture.
An optional coat to slow the green returning on shaded walls.
Any cracks or loose areas found during cleaning are pointed out before they let water in.
Ladders or a platform used safely to reach the upper walls.
Nearby cars, plants and windows covered during the wash.
Nearby paths and drives rinsed after the clean so no residue is left.

Shade, damp and nearby trees let algae grow. It is common on north-facing walls.
Not with a biocide and soft wash. A high-pressure washer is what causes damage.
Often several years, especially with a protective treatment.
Yes, with a gentle approach so the paint is not damaged.
Plants near the wall are covered and rinsed to protect them.
Yes. North-facing walls often need cleaning more often than the rest of the house.
If the render is sound and just dirty, cleaning is usually enough. Recoating is for faded or damaged finishes.
Not always. Many Rainham houses can be reached with ladders or a platform, depending on height.
