Cavity wall insulation removal for Barnstaple properties
We cover Barnstaple and the EX31 postcode district, including nearby Bideford, Tiverton and Exeter. It is about 34 miles north-west of Exeter.
Damp in an insulated Barnstaple home is not always the insulation's fault, so the diagnosis comes before any extraction. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Barnstaple properties, so you can choose who fixes them.
Local weather affects which walls can be filled. 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 the rules side, if cavity wall insulation follows in Barnstaple, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How extraction works
Bricks are carefully removed in a line near the base and at intervals higher up where needed. The fill is broken up and drawn out with an extraction vacuum, the cavity is cleared and checked with a camera, and the bricks are rebuilt in matching mortar. Extracted material is bagged and disposed of properly.
