Existing insulation and guarantee check for Fareham properties

Fareham sits in Hampshire, roughly 11 miles east of Southampton. We work across the PO16 district, including nearby Gosport, Portsmouth and Waterlooville.

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

Exposure matters for every cavity wall. Hampshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

As for paperwork, if cavity wall insulation follows in Fareham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

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.
