Cavity wall insulation removal for Farnham properties
Farnham is among the towns we cover in Surrey, alongside Godalming, Camberley and Guildford. It is roughly 10 miles west of Guildford.
If your Farnham installation has a guarantee, we check it first; the guarantee route may cover the work. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Farnham properties, so you can choose who fixes them.
Every elevation is judged on its own exposure. Much of Surrey sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
On the rules side, if cavity wall insulation follows in Farnham, 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.
