Existing insulation and guarantee check for Newton Aycliffe properties
Newton Aycliffe sits in County Durham, roughly 11 miles south of Durham. We work across the DL5 district, including nearby Bishop Auckland, Darlington and Stockton-on-Tees.
A survey in Newton Aycliffe gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Where a Newton Aycliffe 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. County Durham 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 Newton Aycliffe, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

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.
