Cavity insulation top-up for Dunfermline properties

Dunfermline is among the towns we cover in Fife, alongside Kirkcaldy and Glenrothes. Dunfermline is one of the main towns we cover in Fife.

For semi-detached and terraced homes in Dunfermline, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Most Dunfermline 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. Fife has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

In terms of approvals, in Dunfermline no building warrant is needed for insulation within a wall, but the work must meet the building standards.

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.
