Remove and refill for Newtown properties

Newtown sits in Powys. We work across the SY16 district, including nearby Welshpool and Llandrindod Wells.

We never cold-call in Newtown or anywhere else, and we do not work with doorstep claims companies. Where a Newtown 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.

Every elevation is judged on its own exposure. Parts of Powys 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 Newtown, 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.
