Party wall cavity insulation for Barrow in Furness properties
We cover Barrow in Furness and the LA14 postcode district, including nearby Kendal, Whitehaven and Workington.
If a wall in Barrow in Furness 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. Where a Barrow in Furness property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Exposure matters for every cavity wall. Parts of Cumbria 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 Barrow in Furness 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.
