Render cleaning in Wennington. Algae, mould and dirt removed from render with a low-pressure clean and biocide, without damaging the finish.
Wennington is surrounded by open fields, marshes and trees, and render on houses there tends to go green or black faster than in the town. Algae and mould grow where walls stay damp and shaded, especially on north-facing elevations and below trees.
Render cleaning is done at low pressure. A high-pressure jet can strip the surface off silicone render, damage painted render and drive water into cracks. The aim is to kill and remove the growth, not blast the wall.
A biocide is applied first to kill the algae, mould and lichen down to the roots. It is left to work, then rinsed off with a gentle wash. Some treatments carry on working for weeks afterwards, as weather washes the dead growth away.
Surrounding plants, windows and doors are protected, and runoff is managed so it does not damage lawns or borders.
Cleaning often shows up cracks or areas where the render is failing, and those are pointed out rather than left to get worse. A clean wall is also the right time to apply a protective treatment that slows the growth coming back.
In Wennington, where the conditions that cause the staining will not change, a routine clean every few years keeps the render looking as it should.
Most houses are cleaned in a day, with results visible straight away and improving over the following weeks.
Farm traffic and the busy roads toward the A13 also leave a film of dust and diesel on Wennington walls facing the lanes, which shows as a grey tide mark above the ground. That is lifted with the same gentle clean, and the base of the wall is checked while we are there for splashback damage from rain bouncing off paths. Photos of each elevation, and close-ups of any cracks, stains or hollow patches, are enough to say what the wall needs.
