Cavity wall suitability survey for Magherafelt properties
Magherafelt sits in County Londonderry, around 31 miles south-east of Derry. We work across the BT45 district, including nearby Limavady, Coleraine and Derry.
The written result for your Magherafelt property is plain English: what we found, what it means and what, if anything, to do next. A survey in Magherafelt gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Wind-driven rain is the first thing the surveyor weighs up. 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.
On the rules side, in Magherafelt inserting cavity wall insulation needs a building control application to the council before work starts.
Rules in Northern Ireland
Inserting cavity wall insulation needs a building control application to the council before work starts if insulation work follows.
