Cavity wall insulation for landlords for Antrim properties

We cover Antrim and the BT41 postcode district, including nearby Ballymena, Newtownabbey and Belfast. It is roughly 16 miles north-west of Belfast.

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

Before any material is chosen, exposure is checked. Parts of County Antrim 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 Antrim inserting cavity wall insulation needs a building control application to the council before work starts.

Funding in Northern Ireland
