Cavity cleaning and debris removal for Coleraine properties

Our County Londonderry coverage takes in Coleraine (BT52) and nearby Limavady, Magherafelt and Derry. It is around 27 miles east of Derry.

Damp in an insulated Coleraine home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in Coleraine or anywhere else, and we do not work with doorstep claims companies.

Before any material is chosen, exposure is checked. Parts of County Londonderry 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 Coleraine, inserting cavity wall insulation needs a building control application to the council before work starts.

Why debris matters

A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
