Render cleaning in Edinburgh and Central Scotland. Soft-wash removal of red algae, green algae, dirt and staining from rendered and harled walls, without damaging the finish. Free quotes.
Rendered and harled walls hold moisture, and in the Scottish climate that means algae. Christie's Exterior Cleaning Ltd cleans render using a low-pressure soft-wash method: the wall is treated with a cleaning solution that kills the growth at the root, then rinsed at a pressure the finish can take. High-pressure washing can drive water behind render, crack a weak patch or strip the colour out of a coloured finish, so it is not used on these walls. The result is a wall returned to its original colour rather than one that has simply been blasted.
Green or black patches spreading across a wall, red or pink staining on pale render, dark streaks running down from gutters and window sills, a wall that looks permanently dirty after rain, or render that has visibly changed colour compared with a sheltered section.
Christie's Exterior Cleaning Ltd cleans smooth render, textured and pebbledash finishes, harling and painted render. Work can be combined with a roof clean or gutter clear on the same visit, which is usually cheaper than booking them separately and means one set-up rather than two.
Christie's Exterior Cleaning Ltd has carried out render cleaning in Hawick, removing years of dirt and algae from a property, and completed a full render clean in Tranent that took red algae staining off the whole house alongside a roof scrape and chemical treatment. Both are typical of the exposed, weather-facing walls found across Central Scotland and the Borders.
We look at the render first to check its condition, since older or cracked render needs a gentler approach. Windows, doors and planting are protected, the wall is treated with the cleaning solution, and it is left to work before a controlled low-pressure rinse. Larger walls are worked in sections so nothing dries before it is rinsed. Everything is tidied and rinsed down before we leave.
Christie's Exterior Cleaning Ltd is NEBOSH, CPD and LANTRA certified with public liability cover up to £1 million, and every risk assessment is carried out by NEBOSH qualified personnel. Render is easy to damage with the wrong equipment, so the method is matched to the wall rather than the other way round. Free, fixed-rate quotes with no hidden fees.

Not with the method Christie's Exterior Cleaning Ltd uses. Render is cleaned by soft wash — a treatment that kills the growth, followed by a controlled low-pressure rinse. High-pressure washing is what damages render, and it is not used on these walls.
It is usually a red or pink algae that grows on pale render and spreads quickly in a damp climate. It is not rust and it will not wash off in the rain. Christie's Exterior Cleaning Ltd removed exactly this from a property in Tranent as part of a full render clean.

It depends on how exposed and shaded the wall is. A wall that gets sun and airflow stays clean far longer than a north-facing one under trees. The treatment kills the growth at the root rather than just rinsing the surface, so regrowth is slower than after a plain pressure wash.
