Cavity wall insulation removal for Blackburn properties

If your property is in Blackburn or the BB2 district or nearby Darwen, Accrington and Chorley, it is within our Lancashire coverage. It is around 9 miles east of Preston.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Blackburn properties, so you can choose who fixes them. We never cold-call in Blackburn 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 Lancashire 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 Blackburn, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
