Nobody should pay for extraction on the strength of a damp patch and a guess. The survey exists so that the decision is made on what is actually in the wall.

What the survey is made of:

  • Borescope survey: a camera through the mortar joint, so the cavity is seen rather than assumed.
  • Damp and moisture readings: a grid of readings across the affected wall, inside and where useful outside.
  • The quote: what it contains and what it is for.
  • CIGA guarantee claims: what the Cavity Insulation Guarantee Agency is, what its guarantee covers and how a homeowner makes a claim. We are not part of CIGA; this page explains how you use a guarantee you already have.
  • Questions about surveys.

The survey is the same whether it leads to a job, a claim or a note saying your gutters need clearing. Book a free survey.

What happens next

  • A free survey first We check the wall inside and out and look into the cavity with a small camera. Then you get a fixed price in writing.
  • The insulation comes out Bricks come out at the base of the wall, the old fill is drawn out, and the bricks go back in, pointed to match.
  • A completion certificate You receive a completion certificate when the work is done. If a lender or surveyor has flagged a filled cavity, that certificate is what you show them.
