Areas We Cover
Your home's exterior should look clean, cared for and protected all year round. Chiltern Surface Co provides professional roof cleaning, driveway cleaning, patio cleaning and soft washing services throughout Cookham, using the right method for each surface. From riverside homes and village properties to larger family houses and modern developments, we help Cookham homeowners remove moss, algae, lichen, black spot and weather staining with safe, effective exterior cleaning treatments.

Exterior cleaning in Cookham
Cookham has a distinctive mix of properties, from character homes near the village centre to riverside houses, period cottages, larger family homes and newer residential developments. These properties often use high-quality exterior materials, including clay roof tiles, slate, natural stone, block paving, resin driveways, render and porcelain patios. Each surface needs a careful cleaning method to avoid damage and deliver lasting results.
The local setting close to the River Thames creates ideal conditions for moss, algae and lichen growth, especially on shaded roofs, north-facing patios, tree-lined driveways and garden areas with limited sunlight. Over time, this build-up can make surfaces slippery, stained and tired. Professional exterior cleaning helps restore the appearance of your property while protecting valuable outdoor surfaces.
We inspect every surface before cleaning. Roof tiles, Indian sandstone, resin driveways, concrete, tarmac and brickwork all respond differently to pressure, water flow and treatment products. By choosing the correct method first, we clean thoroughly without causing unnecessary wear.
We know the area and the properties in it — from period stone and brick to modern render and block paving.
Fully insured and trained to recognised standards (Lantra & BWCA) for complete peace of mind.
Surface-specific methods and treatments that don't just clean — they keep surfaces cleaner for longer.
We turn up when we say, work tidily, and leave your property looking its best — with honest advice throughout.

Questions
Black spot and algae on paving, and moss on shaded roof slopes. The village sits low beside the Thames and holds moisture, so organic growth establishes readily on anything that does not get direct sun.
Usually. Black spot is lichen and it roots into the surface, so it needs a treatment and dwell time rather than pressure. Pressure alone takes the top off it and leaves the root behind, which is why it reappears within weeks.
Yes. Older Cookham cottages often have soft brick, lime pointing and clay tile, none of which tolerate the pressure a modern concrete drive can take. We assess the material first and work down from the gentlest method that will do it.
Yes. Planting is covered and rinsed, and we keep treatments off borders and lawns. Village gardens here are often mature and close to the house, so this is part of the setup rather than an afterthought.
