Cavity wall insulation removal for Crawley properties
Crawley sits in West Sussex. We work across the RH11 district, including nearby Horsham, East Grinstead and Haywards Heath.
Damp in an insulated Crawley home is not always the insulation's fault, so the diagnosis comes before any extraction. If your Crawley installation has a guarantee, we check it first; the guarantee route may cover the work.
Exposure matters for every cavity wall. West Sussex has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
As for paperwork, if cavity wall insulation follows in Crawley, 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.
