Cavity cleaning and debris removal for Cardiff properties
If your property is in Cardiff or the CF10 district or nearby Penarth and Barry, it is within our South Glamorgan coverage. Cardiff is one of the main towns we cover in South Glamorgan.
We never cold-call in Cardiff or anywhere else, and we do not work with doorstep claims companies. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Cardiff properties, so you can choose who fixes them.
Wind-driven rain is the first thing the surveyor weighs up. Parts of South 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.
For regulations, if cavity wall insulation follows in Cardiff, 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.
