Remove and refill for Cwmbran properties
Cwmbran sits in Gwent, roughly 5 miles north of Newport. We work across the NP44 district, including nearby Pontypool, Risca and Newport.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Cwmbran properties, so you can choose who fixes them. Where a Cwmbran 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.
Before any material is chosen, exposure is checked. Parts of Gwent 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 Cwmbran, 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.
