What we look for in Coulsdon
As well as Coulsdon itself, we quote in Purley, Banstead and Wallington. 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.
For Coulsdon properties, the survey also confirms whether planning or building control is needed for your address.

Approvals in England
For a house in Coulsdon, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
What happens during the survey?
We measure each elevation, photograph the details that affect the job, check the wall construction and look for damp, cracking and loose render. Ground levels and the damp-proof course are recorded so the system starts in the right place. Eaves depth, window cills, flues, meters, soil pipes, satellite dishes and lights are all noted because each one needs a detail.
