Cavity wall insulation removal in Exeter

For properties in Exeter, cavity wall insulation removal starts with a clear price and ends with a written record of what was found and done. Cavity wall insulation removal takes failed fill out of the cavity, usually by lifting bricks at low level and extracting the material with an industrial vacuum and rods, then cleaning the cavity and rebuilding the brickwork.

Cavity wall insulation removal for Exeter properties

Our Devon coverage takes in Exeter (EX4) and nearby Exmouth, Tiverton and Newton Abbot. Exeter is one of the main towns we cover in Devon.

Where an Exeter wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. We never cold-call in Exeter or anywhere else, and we do not work with doorstep claims companies.

Wind-driven rain is the first thing the surveyor weighs up. 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.

In terms of approvals, if cavity wall insulation follows in Exeter, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

If you have a guarantee

Contact your original installer first. If that does not resolve it within two months, CIGA's process applies for CIGA-guaranteed installs. Removing insulation yourself can void a guarantee, so speak to the provider before work.
