Cavity cleaning and debris removal for Newtown properties
We cover Newtown and the SY16 postcode district, including nearby Welshpool and Llandrindod Wells. Newtown is one of the main towns we cover in Powys.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Newtown properties, so you can choose who fixes them. If your Newtown installation has a guarantee, we check it first; the guarantee route may cover the work.
Exposure matters for every cavity wall. Parts of Powys face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
For regulations, if cavity wall insulation follows in Newtown, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Why debris matters
A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
