Blown mineral wool insulation for Portadown properties

Portadown is among the towns we cover in County Armagh, alongside Craigavon, Lurgan and Armagh. It is around 3 miles south-west of Craigavon.

Where a Portadown property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Portadown properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.

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 Portadown 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 is it not the right choice?

Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.

What is included in Portadown

Blown mineral wool insulation in Portadown: questions

Is my Portadown home too exposed for cavity insulation?

Do you work on rented homes in Portadown?

Yes. Landlords and agents in Portadown can book batch visits, and work is arranged around tenants.

Do you cold-call in Portadown?

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