Damp investigation after cavity insulation for Magherafelt properties
Magherafelt sits in County Londonderry, about 31 miles south-east of Derry. We work across the BT45 district, including nearby Limavady, Coleraine and Derry.
Damp in an insulated Magherafelt home is not always the insulation's fault, so the diagnosis comes before any extraction. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Magherafelt properties, so you can choose who fixes them.
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.
In terms of approvals, if cavity wall insulation follows in Magherafelt, inserting cavity wall insulation needs a building control application to the council before work starts.
