Remove and refill for Gorseinon properties

Gorseinon is among the towns we cover in West Glamorgan, alongside Swansea, Briton Ferry and Neath. It is about 6 miles north-west of Swansea.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Gorseinon properties, so you can choose who fixes them. Damp in an insulated Gorseinon home is not always the insulation's fault, so the diagnosis comes before any extraction.

Before any material is chosen, exposure is checked. Parts of West 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 Gorseinon, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Why refill at all?

Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
