Existing insulation and guarantee check for Haverfordwest properties
Our Dyfed coverage takes in Haverfordwest (SA61) and nearby Pembroke Dock, Carmarthen and Llanelli. It is about 29 miles west of Carmarthen.
The written result for your Haverfordwest property is plain English: what we found, what it means and what, if anything, to do next. Where a Haverfordwest wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Wind-driven rain is the first thing the surveyor weighs up. 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.

How to tell if a house already has cavity insulation
Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
