What we look for in Chesham
We cover Chesham and nearby Amersham, Berkhamsted and Chalfont St Peter. It's roughly 25 miles from Chesham to Milton Keynes, the largest town in Buckinghamshire. 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 Buckinghamshire 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.
Silicone suits most rendering jobs in Chesham, either on its own or over insulation.

Approvals in England
For a house in Chesham, 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
Is silicone render maintenance-free?
Not quite. It stays cleaner than most renders because water runs off and dries quickly, but north-facing or tree-shaded walls can still gather algae. A gentle biocide wash every few years keeps it looking new. Pressure washing is avoided because it can damage the surface.

Silicone render in Chesham: questions
Does silicone render crack?
The mesh-reinforced base coat and the render's flexibility make cracking much less likely than with sand and cement, but structural movement in the wall can still show through.
Can silicone render go over old render?
If the old render is sound and well bonded, often yes after cleaning and priming. Hollow or cracked areas are cut out and repaired first.
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
