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.

What happens at the survey

  • An outside walk round: gutters, downpipes, pointing, render, sills, ground levels, airbricks and the pattern of injection holes.
  • Moisture readings inside, in a grid across the affected wall and against a dry wall for comparison.
  • A borescope through 10mm holes in the mortar joints of the elevations that need it, to see the fill, the ties and the base of the cavity. Holes are filled before we leave.
  • Thermal images where cold spots are part of the picture.
  • A look at any paperwork you have about the insulation, in case a guarantee covers it.

Allow one to two hours for a typical house.

02

What you get afterwards

A quote by email: what we found on each elevation with the stills and readings, our view of the cause, what we recommend and what we would not, what other trades the house needs, and, if there is work for us, a fixed quotation as a separate document. It is yours to keep, to show to other firms, or to use in a guarantee claim.

03

What to tell us on the form

Your name, postcode, email and phone number; the type of house; and in the message, what you are seeing, where, and roughly when it started. If you know when the insulation was installed or what it is, say so.

The promise

We reply within one working day to arrange a free survey and quote. Bad weather occasionally moves a date; we tell you as early as we can.

We cover mainland England, Scotland and Wales. If you are unsure whether we cover your address, ask and we will say.
