What we look for in Nailsea
We also cover Portishead and Clevedon, close to Nailsea. Nailsea is about 18 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.
For Nailsea homeowners matching a new extension to an existing rendered house, we compare monocouche and silicone samples first.

England: planning and regulations
For a house in Nailsea, 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.
Why does monocouche sometimes look patchy?
Colour variation (often called shading) can appear if it's applied in poor weather, on walls with uneven suction, or in sections on different days. Working an elevation in one go in suitable conditions keeps the colour even.

Monocouche render in Nailsea: questions
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
Does monocouche need painting?
No — it's through-coloured. Cleaning every few years keeps it looking fresh.
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
