Damp investigation after cavity insulation for Wrexham properties
If your property is in Wrexham or the LL13 district or nearby Rhosllannerchrugog, Buckley and Hawarden, it is within our Clwyd coverage. Wrexham is one of the main towns we cover in Clwyd.
We never cold-call in Wrexham or anywhere else, and we do not work with doorstep claims companies. Where a Wrexham 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.
Local weather affects which walls can be filled. 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 Wrexham, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Common causes we check
Defective pointing, cracked render and porous bricks letting rain in; leaking gutters and downpipes; fill bridging the cavity where mortar droppings or debris have collected; ground levels above the damp-proof course; and condensation from cooking, drying clothes and too little ventilation.
