Existing insulation and guarantee check for Caerphilly properties
Caerphilly sits in Gwent, roughly 9 miles west of Newport. We work across the CF83 district, including nearby Risca, Newport and Cwmbran.
A survey in Caerphilly gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Caerphilly is photographed and logged, so you have a record to show a buyer, lender or contractor.
Every elevation is judged on its own exposure. Parts of Gwent 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.
As for paperwork, if cavity wall insulation follows in Caerphilly, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

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.
