Damp investigation after cavity insulation for Lisburn properties
Lisburn is among the towns we cover in County Antrim, alongside Belfast, Newtownabbey and Carrickfergus. It is around 7 miles south-west of Belfast.
If your Lisburn installation has a guarantee, we check it first; the guarantee route may cover the work. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Lisburn properties, so you can choose who fixes them.
Exposure matters for every cavity wall. 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.
For regulations, if cavity wall insulation follows in Lisburn, inserting cavity wall insulation needs a building control application to the council before work starts.
