Cavity wall insulation for flats for Armagh properties

Our County Armagh coverage takes in Armagh (BT61) and nearby Portadown, Craigavon and Lurgan. It is roughly 11 miles south-west of Craigavon.

Blocks of flats in Armagh are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Armagh, we survey in batches and return a result sheet and fixed price per address.

Wind-driven rain is the first thing the surveyor weighs up. Parts of County Armagh 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, in Armagh 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.
