Cavity wall insulation removal in Lisburn

Cavity wall insulation removal takes failed fill out of the cavity, usually by lifting bricks at low level and extracting the material with an industrial vacuum and rods, then cleaning the cavity and rebuilding the brickwork. In Lisburn the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Cavity wall insulation removal for Lisburn properties

Lisburn sits in County Antrim, around 7 miles south-west of Belfast. We work across the BT28 district, including nearby Belfast, Newtownabbey and Carrickfergus.

We never cold-call in Lisburn or anywhere else, and we do not work with doorstep claims companies. Where a Lisburn wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.

Local weather affects which walls can be filled. 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, 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

If you have a guarantee

Contact your original installer first. If that does not resolve it within two months, CIGA's process applies for CIGA-guaranteed installs. Removing insulation yourself can void a guarantee, so speak to the provider before work.
