Existing insulation and guarantee check for Walthamstow properties
Our Greater London coverage takes in Walthamstow (E17) and nearby Leytonstone, Tottenham and Woodford Green. It is about 7 miles north-east of London.
Every inspection point in Walthamstow is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Walthamstow 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. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
On the rules side, if cavity wall insulation follows in Walthamstow, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
