Cavity wall insulation in Stranraer

Cavity wall insulation for Stranraer properties

We cover Stranraer and the DG9 postcode district, including nearby Castle Douglas.

For semi-detached and terraced homes in Stranraer, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Most Stranraer 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 Dumfries and Galloway 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 Stranraer no building warrant is needed for insulation within a wall, but the work must meet the building standards.

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.
