Cavity wall suitability survey for Lisburn properties
We cover Lisburn and the BT28 postcode district, including nearby Belfast, Newtownabbey and Carrickfergus. It is around 7 miles south-west of Belfast.
Every inspection point in Lisburn is photographed and logged, so you have a record to show a buyer, lender or contractor. The written result for your Lisburn property is plain English: what we found, what it means and what, if anything, to do next.
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.
In terms of approvals, 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.
