Existing insulation and guarantee check for Washington properties

If your property is in Washington or the NE38 district or nearby Houghton-Le-Spring, Hebburn and Sunderland, it is within our Tyne and Wear coverage. It is roughly 6 miles south-east of Newcastle upon Tyne.

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

Exposure matters for every cavity wall. 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.

For regulations, if cavity wall insulation follows in Washington, 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.
