Cavity wall insulation in Cookstown

Cavity wall insulation in Cookstown starts with a free survey of the property, then a written result and a fixed price before any work is booked.

Cavity wall insulation for Cookstown properties

Cookstown sits in County Tyrone, around 22 miles east of Omagh. We work across the BT80 district, including nearby Dungannon and Omagh.

For semi-detached and terraced homes in Cookstown, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Most Cookstown 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.

Every elevation is judged on its own exposure. 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.

For regulations, in Cookstown inserting cavity wall insulation needs a building control application to the council before work starts.

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.
