Existing insulation and guarantee check for Muswell Hill properties
If your property is in Muswell Hill or the N10 district or nearby Wood Green, Archway and Finchley, it is within our Greater London coverage. It is around 6 miles north of London.
Every inspection point in Muswell Hill is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Muswell Hill 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.
For regulations, if cavity wall insulation follows in Muswell Hill, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

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.
