Existing insulation and guarantee check for Prescot properties
Prescot sits in Merseyside, roughly 7 miles east of Liverpool. We work across the L34 district, including nearby Huyton, St Helens and Halewood.
A survey in Prescot gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Where a Prescot wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Local weather affects which walls can be filled. Merseyside 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.
In terms of approvals, if cavity wall insulation follows in Prescot, 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.
