Damp investigation after cavity insulation in Maesteg

Damp investigation after cavity insulation in Maesteg is priced before you book, and what we find is written up with photos. A damp investigation finds out why an insulated wall is showing damp or mould: rain getting in through defects, bridged or wet fill, debris in the cavity, a breached damp-proof course, or condensation.

Damp investigation after cavity insulation for Maesteg properties

Maesteg is among the towns we cover in Mid Glamorgan, alongside Bridgend, Tonypandy and Rhondda. It is around 8 miles north-west of Bridgend.

Where a Maesteg wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Maesteg properties, so you can choose who fixes them.

Local weather affects which walls can be filled. 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.

On the rules side, if cavity wall insulation follows in Maesteg, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
