Cavity wall insulation in Dungannon

For homes and buildings in Dungannon, cavity wall insulation is arranged survey-first: we check the property, tell you plainly what we found, and price it. Cavity wall insulation fills the gap between the two leaves of a brick or block wall with a certified insulating material, blown in through small holes drilled from outside.

Cavity wall insulation for Dungannon properties

Our County Tyrone coverage takes in Dungannon (BT71) and nearby Cookstown and Omagh. It is roughly 25 miles east of Omagh.

Where a Dungannon property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Most Dungannon houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.

Exposure matters for every cavity wall. Parts of County Tyrone 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 Dungannon 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.

What happens on the day?

Holes of around 22mm are drilled in the mortar joints in a set pattern, roughly a metre apart. The insulation is blown in from the bottom up until each section is full, then every hole is filled with colour-matched mortar. Air bricks and flues are protected, and a cavity barrier is fitted where your wall joins a neighbour's.

Cavity wall insulation in Dungannon: questions

How soon can you visit in Dungannon?

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 Dungannon home too exposed for cavity insulation?

Parts of County Tyrone 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.

In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000. We cannot promise funding, but we will point you to the right official route.
