Before we quote in Blackheath
Surveys in Blackheath also cover the surrounding SE3 district and towns such as Catford and Eltham. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London 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.
We clean render in Blackheath with low pressure only, so thin-coat and EWI finishes aren't damaged.

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.

Usually not for a two-storey house; poles and low-pressure equipment reach most walls.
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.
