Cavity cleaning and debris removal for Belfast properties
Belfast is among the towns we cover in County Antrim, alongside Newtownabbey, Lisburn and Carrickfergus. Belfast is one of the main towns we cover in County Antrim.
We never cold-call in Belfast or anywhere else, and we do not work with doorstep claims companies. Damp in an insulated Belfast home is not always the insulation's fault, so the diagnosis comes before any extraction.
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 compliance, if cavity wall insulation follows in Belfast, inserting cavity wall insulation needs a building control application to the council before work starts.

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.
