Cavity wall insulation removal for Gainsborough properties

Our Lincolnshire coverage takes in Gainsborough (DN21) and nearby Scunthorpe and Lincoln. It is about 14 miles north-west of Lincoln.

Damp in an insulated Gainsborough home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in Gainsborough or anywhere else, and we do not work with doorstep claims companies.

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

As for paperwork, if cavity wall insulation follows in Gainsborough, 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.
