Before we quote in Portishead
Surveys in Portishead also cover the surrounding BS20 district and towns such as Nailsea and Clevedon. Portishead sits around 19 miles from Bath. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Somerset: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
Silicone suits most rendering jobs in Portishead, either on its own or over insulation.

Permissions in England
Planning in Portishead follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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 Portishead: questions
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.
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.
Do you cover Portishead?
Yes — we survey and quote silicone render in Portishead (BS20) and nearby Nailsea, Clevedon and Kingswood, with a fixed written price before any work starts.
