Cavity insulation top-up in Lurgan

Cavity insulation top-up in Lurgan starts with a free survey of the property, then a written result and a fixed price before any work is booked. A cavity top-up fills voids left by an older installation: missed panels around windows, settled fibre, areas disturbed by an extension or new window.

Cavity insulation top-up for Lurgan properties

Our County Armagh coverage takes in Lurgan (BT66) and nearby Craigavon, Portadown and Armagh. It is about 2 miles east of Craigavon.

Where a Lurgan property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. If a wall in Lurgan is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.

Every elevation is judged on its own exposure. Parts of County Armagh 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 Lurgan inserting cavity wall insulation needs a building control application to the council before work starts.

Funding in Northern Ireland

In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000.

When a top-up is not enough

If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.

Cavity insulation top-up in Lurgan: questions

Do you cold-call in Lurgan?

No. We only come out when you have asked us to. If someone cold-calls offering free insulation, check before you agree to anything.

Do you cover Lurgan?

Yes. Lurgan and the BT66 postcode district are within our County Armagh coverage, along with nearby Craigavon and Portadown.

Which building regulations route applies in Lurgan?

Lurgan is in Northern Ireland, so inserting cavity wall insulation needs a building control application to the council before work starts. We confirm the route in writing on your quote.

Is my Lurgan home too exposed for cavity insulation?

Parts of County Armagh get some of the heaviest wind-driven rain in the UK, so the survey is stricter and some walls are better left unfilled. The survey records the exposure of each wall before recommending a material, or recommending against filling.
