Homes and walls in Nailsea
We also cover Portishead and Clevedon, close to Nailsea. Nailsea sits around 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.
On brick terraces in Nailsea, slips can insulate the wall while keeping the street's look.

Approvals in England
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 choose brick slips over render?
Permitted development for houses in England and Wales generally expects materials of a similar appearance to the existing walls. On a brick terrace or estate, render can change the street scene, while brick slips keep it. Some owners simply prefer the brick look.

Brick slip EWI in Nailsea: questions
Is a brick slip finish more expensive?
Yes — roughly £70–£120 per m² more than render, because of materials and slower installation.
Do brick slips fall off?
Not when installed to the system manufacturer's specification, with the right adhesive, fixings and pointing.
Will brick slips match my neighbours' brick?
We source slips to get close in colour and texture and show samples beforehand, but an exact match to weathered brick isn't always possible.
