Cavity cleaning and debris removal for Merthyr Tydfil properties
If your property is in Merthyr Tydfil or the CF47 district or nearby Aberdare, Rhondda and Tonypandy, it is within our Mid Glamorgan coverage. It is roughly 19 miles north-east of Bridgend.
Damp in an insulated Merthyr Tydfil home is not always the insulation's fault, so the diagnosis comes before any extraction. If your Merthyr Tydfil installation has a guarantee, we check it first; the guarantee route may cover the work.
Every elevation is judged on its own exposure. Parts of Mid Glamorgan 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.
In terms of approvals, if cavity wall insulation follows in Merthyr Tydfil, 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.
