Existing insulation and guarantee check across Tyne and Wear

We cover 13 towns in Tyne and Wear, including Newcastle upon Tyne, Sunderland, South Shields, Gateshead, Washington and more.

Local weather affects which walls can be filled. Tyne and Wear 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.

Every inspection point in Tyne and Wear is photographed and logged, so you have a record to show a buyer, lender or contractor. The written result for your Tyne and Wear property is plain English: what we found, what it means and what, if anything, to do next.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.
