Remove and refill for Haverfordwest properties
Our Dyfed coverage takes in Haverfordwest (SA61) and nearby Pembroke Dock, Carmarthen and Llanelli. It is around 29 miles west of Carmarthen.
If your Haverfordwest installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Haverfordwest 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 Dyfed 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.
As for paperwork, if cavity wall insulation follows in Haverfordwest, 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.
