Cavity wall insulation removal for Cowes properties
Cowes sits in the Isle of Wight, around 6 miles west of Ryde. We work across the PO31 district, including nearby Ryde and Sandown.
Damp in an insulated Cowes 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 Cowes properties, so you can choose who fixes them.
Local weather affects which walls can be filled. The Isle of Wight 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.
On compliance, if cavity wall insulation follows in Cowes, 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.
