Re-rendering in Portishead
From Portishead to Nailsea, we price re-rendering after a measured survey — no guesswork, and no work starts until the price is agreed in writing. On older houses in Portishead, stripping old render often reveals mortar repairs that are best done before re-rendering.

Portishead: walls, weather and approvals
We also cover Nailsea and Clevedon, close to Portishead. 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.
For Portishead re-render jobs, we check whether building control needs notifying for your wall area.

Planning and building control in England
For a house in Portishead, 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.
Which new render should I choose?
On older solid walls, breathable lime or a mineral system is often safest. On sound modern masonry, silicone over a mesh base coat gives a durable, low-maintenance finish. If insulation is added, the finish is the one specified for the EWI system.

Re-rendering in Portishead: questions
Do I need building control for re-rendering?
In England and Wales, re-rendering more than half of a wall's area — or more than a quarter of the whole building's envelope — is controlled work under Part L, so usually yes. We explain how it's handled in the quote.
How do I know if my render has failed?
Signs include cracks, hollow sound when tapped, bulging, pieces falling off, and damp patches inside behind cracked areas.
Is it worth adding insulation?
On solid or concrete walls it's usually the most cost-effective time to do it, because access and preparation are already paid for.

Yes — we survey and quote re-rendering in Portishead (BS20) and nearby Nailsea, Clevedon and Kingswood, with a fixed written price before any work starts.
