Before we quote in Portslade
Surveys in Portslade also cover the surrounding BN41 district and towns such as Hove and Brighton. It's roughly 3 miles from Portslade to Brighton, the largest town in East Sussex. 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.
Exposure to wind-driven rain varies across East Sussex: 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.
On tree-shaded or north-facing walls in Portslade, silicone's water repellence helps it stay cleaner for longer.

Planning and building control in England
For a house in Portslade, 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 Portslade: questions
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
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.
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.
