Wall & Render Cleaning in London — Professional Results, Fair Prices
Professional wall and render cleaning in London removes algae, pollution staining and weathering from all exterior wall surfaces. We use soft washing, DOFF steam cleaning, and surface-appropriate techniques to restore your walls without damaging brickwork, render or stone.
Wall Types We Clean
Render
K-Rend, monocouche, silicone render and traditional sand and cement render — all cleaned by soft wash, never abrasive methods.
Brick
Victorian red brick, London stock brick and engineering brick. Soft bricks need an especially gentle approach.
Stone
Portland stone, Bath stone and limestone facades — assessed individually for porosity and condition.
Painted Masonry
Cleaned carefully to avoid stripping sound paintwork.
Our Methods
Soft Washing
Biocidal treatment plus low-pressure rinse — our standard method for render and most brickwork. Removes algae and green growth without cracking or etching.
DOFF Steam Cleaning
Superheated water at low pressure, ideal for heritage stone and delicate period brickwork where standard methods are too aggressive.
Why not high pressure: high-pressure washing can crack render, etch soft brick, and force water into the wall structure. Conservation areas often restrict cleaning methods on listed buildings — our soft washing and DOFF approach is suitable for sensitive properties.
What We Treat
Algae and green growth, red algae, pollution staining and carbon deposits common on London's exterior walls, and general weathering build-up. We assess condition before treatment to avoid damage to render or soft brickwork — particularly important on conservation area properties.
