Party wall cavity insulation for Bideford properties
If your property is in Bideford or the EX39 district or nearby Barnstaple, Tiverton and Exeter, it is within our Devon coverage. It is around 36 miles north-west of Exeter.
Bideford properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. If a wall in Bideford is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Before any material is chosen, exposure is checked. Parts of Devon 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.
On compliance, in Bideford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
