Remove and refill for Bangor, County Down properties

Bangor sits in County Down. We work across the BT20 district, including nearby Newtownards and Downpatrick.

If your Bangor installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Bangor home is not always the insulation's fault, so the diagnosis comes before any extraction.

Before any material is chosen, exposure is checked. Parts of County Down 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.

As for paperwork, if cavity wall insulation follows in Bangor, 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.

Why refill at all?

Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
