Homes and walls in Windsor
We also cover Slough and Egham, close to Windsor. Windsor is about 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.
If you're comparing quotes in Windsor, the written specification makes it easier to compare like for like.

England: planning and regulations
For a house in Windsor, 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.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
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.
