Driveway & Patio Cleaning Specialists across England

A British driveway turns green by stealth. Six months of damp weather, a north-facing aspect or a row of overhanging trees and the once-clean block paving disappears under a film of algae, moss colonies push up between the joints and black weathering streaks down every kerb. Most homeowners reach for a hire-shop pressure washer, blast the surface for an afternoon and end up with the same green film back inside a year. A proper driveway cleaner does the job differently — and the result lasts three to five years rather than three to five months.

What pressure washing alone misses

The visible green coating is only the top layer. Underneath sits a much deeper biofilm of fungal hyphae, mycelium and bacterial colonies that have rooted themselves into the porous concrete or stone surface. A domestic washer at 130 bar removes the surface layer but does nothing to the root system, so the regrowth is almost guaranteed. Worse, an aggressive blast at the wrong angle blows the kiln-dried jointing sand out of the gaps, leaving the blocks loose, encouraging weed seeds to take hold and accelerating the next round of moss growth.

A professional clean works in stages. A pre-treatment biocide is applied and allowed to dwell — fifteen to thirty minutes is typical — to kill the biofilm down through the porosity. Then a controlled pressure wash at the correct nozzle and standoff distance lifts the dead organic matter without disturbing the substrate. The drive is allowed to dry, fresh kiln-dried sand is brushed into the joints and a clear penetrating sealer is optionally applied to lock everything in place. The result is a surface that resists regrowth for years, not months.

Cleaning, sealing and restoration in one visit

Our network of driveway cleaners cover the full spectrum: block paving cleaning, natural stone and Indian sandstone cleaning, tarmac and asphalt jet washing, patio cleaning, decking restoration, gutter and soffit cleaning where access allows. Most also offer a sanding and sealing package as an add-on, which is where the long-term value really sits — a sealed drive that takes a fraction of the maintenance work over the next five years.

Eco-friendly chemistry where it matters

Modern biocide treatments are far gentler than the old chlorine bleach approach. Quaternary ammonium compounds and benzalkonium chloride blends are biodegradable, safe around pets and plants once dry, and effective at much lower concentrations. Run-off discharges to the foul drain rather than the surface water network where regulations require it.
