Damp investigation after cavity insulation for Coleraine properties
Our County Londonderry coverage takes in Coleraine (BT52) and nearby Limavady, Magherafelt and Derry. It is about 27 miles east of Derry.
If your Coleraine installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Coleraine 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 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.
In terms of approvals, if cavity wall insulation follows in Coleraine, inserting cavity wall insulation needs a building control application to the council before work starts.
