Existing insulation and guarantee check for Lisburn properties

Our County Antrim coverage takes in Lisburn (BT28) and nearby Belfast, Newtownabbey and Carrickfergus. It is around 7 miles south-west of Belfast.

The written result for your Lisburn property is plain English: what we found, what it means and what, if anything, to do next. Where a Lisburn wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

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.

On the rules side, if cavity wall insulation follows in Lisburn, 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.

Tracing a guarantee

Many cavity fills carry a 25-year guarantee from the Cavity Insulation Guarantee Agency (CIGA). CIGA can confirm whether a property is covered and can issue a duplicate guarantee for a fee; at the time of writing that fee is £60 including VAT, and proof of ownership is required.
