What Our External Cleaners Do
The full breadth of external cleaning work we carry out across London and Surrey — in detail.
Driveway & Patio Pressure Washing
Block paving, concrete, natural stone and tarmac all clean differently, and treating them the same is how surfaces get ruined. We match pressure and technique to the material, lift years of grime, moss and algae, and re-sand block paving joints where needed.
Render & Cladding Softwashing
Painted render, K-rend and cladding streaked with green algae or red staining need low-pressure softwashing with the right treatments — high pressure just drives water in and strips the finish. We clean these surfaces gently and the results last far longer.
Gutter Clearing & Downpipe Flushing
Blocked gutters quietly cause damp walls, rotten fascias and flooded paths. We clear leaves, moss and silt by hand and vacuum, flush the downpipes through, and check water is actually running away before we call it done.
Windows, Frames & Fascias
Exterior window cleaning including the frames, sills and fascias that regular window cleaners skip. Combined with a gutter or render clean, it finishes the job properly — the whole frontage looking cared for, not just the glass.
Decking, Paths & Steps
Green, slippery decking and paths are an accident waiting to happen, especially through winter. We clean timber and stone walkways with appropriate pressure, treat the growth causing the slipperiness, and bring back the original surface colour.
Roofs, Conservatories & Awkward Areas
Moss-laden roofs, dulled conservatory glazing, bin stores and side returns — the areas that show their neglect first. We use careful methods suited to fragile surfaces and leave the parts of the property you don't usually reach as clean as the parts you do.

Common External Cleaning Problems We Fix
Sound familiar? Here's what's usually behind it — and how we put it right.
"The patio or driveway has turned green and gets slippery when wet"
Algae and lichen thrive on shaded paving and become genuinely dangerous in winter. We pressure-wash with the right nozzle and pressure for the surface — block paving, sandstone and concrete all take different treatment — then re-sand joints where needed.
"Gutters are overflowing or plants are growing out of them"
Blocked gutters quietly push water into fascias and brickwork, and the damp patch shows up indoors months later. We clear the run by hand and vacuum, check the downpipes actually flow, and photograph the result so you can see it's done.
"White uPVC, fascias and window frames have gone grey and grimy"
Traffic film and algae dull uPVC long before it needs replacing. We wash frames, fascias, soffits and cladding with non-aggressive cleaners that lift the grime without bleaching or scratching the surface — most homes come up close to new.
"The conservatory roof is too dirty to let light through"
Glass and polycarbonate roofs need low-pressure washing and the correct chemicals — a pressure lance at full blast destroys seals. We clean roofs, frames and finials safely from ladders or water-fed poles, and the difference inside is immediate.
