Cavity cleaning and debris removal for Antrim properties
If your property is in Antrim or the BT41 district or nearby Ballymena, Newtownabbey and Belfast, it is within our County Antrim coverage. It is around 16 miles north-west of Belfast.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Antrim properties, so you can choose who fixes them. If your Antrim installation has a guarantee, we check it first; the guarantee route may cover the work.
Wind-driven rain is the first thing the surveyor weighs up. 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.
On the rules side, if cavity wall insulation follows in Antrim, 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.

Why debris matters
A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
