Homes and walls in Powys
Mid Wales is largely rural, with stone farmhouses, cottages and market-town terraces, many of them solid-walled.
Parts of Powys fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
On older houses in Powys, stripping old render often reveals mortar repairs that are best done before re-rendering.

Wales: planning and regulations
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.
Why should I think about insulation when re-rendering?
In England and Wales, replacing render on more than half of a wall's area is treated as renovating a thermal element, so the wall is expected to be upgraded to about 0.30 W/m²K where that's technically, functionally and economically feasible. The scaffold, preparation and finish are being paid for anyway, so the extra cost of insulation is lower than doing it later. We price both options.

Re-rendering in Powys: questions
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 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.
Do you cover all of Powys?
Yes. We survey and quote re-rendering across Powys, including Newtown, Brecon, Welshpool, Llandrindod Wells.
Do I need planning permission 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.
