Existing insulation and guarantee check for Rhosllannerchrugog properties

Our Clwyd coverage takes in Rhosllannerchrugog (LL14) and nearby Wrexham, Buckley and Hawarden. It is around 4 miles south-west of Wrexham.

Where a Rhosllannerchrugog wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Every inspection point in Rhosllannerchrugog is photographed and logged, so you have a record to show a buyer, lender or contractor.

Wind-driven rain is the first thing the surveyor weighs up. Parts of Clwyd 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 Rhosllannerchrugog, 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.
