Cavity wall insulation for flats 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.
Blocks of flats in Magherafelt are surveyed as a whole, because the cavity runs across every flat in the building. Work on Magherafelt rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer.
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.
On the rules side, in Magherafelt inserting cavity wall insulation needs a building control application to the council before work starts.

Why one flat cannot usually be done alone
The cavity runs continuously across the building. The Energy Saving Trust notes that flats need agreement from the whole block. Filling one flat's walls in isolation leaves gaps, and the freeholder normally owns the structure.
