Party wall cavity insulation for Annan properties
If your property is in Annan or the DG12 district or nearby Dumfries and Castle Douglas, it is within our Dumfries and Galloway coverage. It is about 16 miles east of Dumfries.
Most Annan 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. Annan properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Local weather affects which walls can be filled. 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 Annan no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Why a party wall loses heat
Many semi-detached and terraced homes built with cavity separating walls have that cavity open to the loft. Air moves up the cavity and out at the top, a loss sometimes called the party wall bypass. Filling the cavity and sealing the top stops it.
What is included in Annan
- Sealing at the top of the cavity
