Windsor: walls, weather and approvals
Surveys in Windsor also cover the surrounding SL4 district and towns such as Slough and Egham. Windsor sits around 16 miles from Reading. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Berkshire sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
Shaded and north-facing walls in Windsor often need render cleaning sooner than sunny elevations.

Planning and building control in England
Repairs, cleaning and like-for-like patching don't usually need planning permission or building control. If repairs grow into re-rendering more than half of a wall, Building Regulations energy rules can apply.
How long does cleaned render stay clean?
It depends on shade, trees and exposure. Many walls stay clean for several years after a biocide treatment. North-facing, shaded and damp walls may need treating more often.

Render cleaning in Windsor: questions
Is render cleaning safe for EWI?
Yes, using low pressure and products suitable for thin-coat render.
Will the green come back?
The biocide slows regrowth considerably, but shaded, damp walls can need retreating every few years.
Can faded render be refreshed?
Yes — a compatible silicone paint restores colour without making the wall less breathable.
Do you cover Windsor?
Yes — we survey and quote render cleaning in Windsor (SL4) and nearby Slough, Egham and Staines, with a fixed written price before any work starts.
