Existing insulation and guarantee check for Truro properties

Our Cornwall coverage takes in Truro (TR1) and nearby Falmouth, Redruth and Newquay. Truro is one of the main towns we cover in Cornwall.

Where a Truro wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Buyers and sellers in Truro often book this check when a survey report or EPC raises questions about the walls.

Before any material is chosen, exposure is checked. 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 Truro, 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.
