Existing insulation and guarantee check for Falmouth properties

Our Cornwall coverage takes in Falmouth (TR11) and nearby Truro, Redruth and Camborne. It is around 7 miles south of Truro.

The written result for your Falmouth property is plain English: what we found, what it means and what, if anything, to do next. A survey in Falmouth gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Local weather affects which walls can be filled. Parts of Cornwall 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 compliance, if cavity wall insulation follows in Falmouth, 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.

Tracing a guarantee

Many cavity fills carry a 25-year guarantee from the Cavity Insulation Guarantee Agency (CIGA). CIGA can confirm whether a property is covered and can issue a duplicate guarantee for a fee; at the time of writing that fee is £60 including VAT, and proof of ownership is required.
