Cavity insulation top-up in Armagh

Cavity insulation top-up for Armagh properties

We cover Armagh and the BT61 postcode district, including nearby Portadown, Craigavon and Lurgan. It is roughly 11 miles south-west of Craigavon.

Armagh properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. For semi-detached and terraced homes in Armagh, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

Before any material is chosen, exposure is checked. 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 Armagh 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.

How do I know if my walls need a top-up?

Cold patches on internal walls, a thermal image showing uneven heat loss, or an EPC that says 'filled cavity' when parts of the house feel colder are all signs. Extensions are a common cause: the new wall is insulated as built, but the old wall it joins may have been left partly empty.

Cavity insulation top-up in Armagh: questions

Is the survey free in Armagh?

Yes when it is for an install quote. Standalone reports for Armagh buyers, sellers or landlords who do not need an install quote are priced before you book.

We arrange dates when you get in touch. Availability varies through the year, so we give you real dates rather than a promise on the website.

Is my Armagh 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.

Which building regulations route applies in Armagh?

Armagh 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.
