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.
