Homes and walls in South Glamorgan

Permissions in Wales
Permitted development rules for houses in Wales are similar to England's: a similar-appearance finish on a house is often permitted, while conservation areas, National Parks, Areas of Outstanding Natural Beauty, flats, commercial buildings and listed buildings need permission or consent. Your local planning authority has the final word.
The Building Regulations as they apply in Wales treat insulating or re-rendering more than half of a wall's area, or more than a quarter of the building's whole envelope, as renovating a thermal element, with Approved Document L (Wales) setting the target. Building control is involved before work starts.
What's involved in stripping old render?
The render is hacked off, usually with breakers, and the debris bagged or skipped. The wall is then inspected: loose bricks, eroded mortar and damp spots are repaired, and the surface is prepared to suit the new system.

Re-rendering in South Glamorgan: 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.
Do you cover all of South Glamorgan?
Yes. We survey and quote re-rendering across South Glamorgan, including Cardiff, Barry, Penarth.
