Party wall cavity insulation for Castle Douglas properties
Castle Douglas sits in Dumfries and Galloway, roughly 17 miles south-west of Dumfries. We work across the DG7 district, including nearby Dumfries, Annan and Stranraer.
A suitable wall in Castle Douglas is usually filled in a single day from outside, with drill holes made good to match the pointing. Most Castle Douglas 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.
Before any material is chosen, exposure is checked. 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.
In terms of approvals, in Castle Douglas 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.
