Cavity Reset Insulation Removal surveys, removes and makes good failed cavity wall insulation across mainland England, Scotland and Wales. Where a job needs a scaffolder, a plasterer or a wall tie firm, we bring one in and tell you who they are.

01

Survey before quote, always

We do not price a house from a photograph or a phone description, because the price depends on what is in the cavity and how wet it is, and neither can be seen from outside. The survey is free, the quote is in writing, and the quotation comes after it.

Every finding in the quote has something behind it: a borescope still, a moisture reading, a thermal image, a photograph of a blocked gutter. Where the evidence supports a firm view, we give one.

02

Only the work the wall needs

If one elevation is wet and three are dry, we quote for one. If the fill is sound and the damp is a failed cavity tray, we say so and the quote tells you who to call.

03

Fixed written prices, paid on completion

The quotation is fixed for the work described in it and the quote describes that work in detail. If the borescope finds something the survey could not see, we stop and talk to you before doing anything not on the quote.

04

Making good

The bricks that come out go back in: the originals, bedded and pointed to match. Injection holes are repointed on the elevations we work on.

05

What we do not do

We remove failed insulation and clear the cavity. We refill it with the thermal bead system if you want it refilled, or leave it clear if that is what you want or what the wall needs. We do not replace wall ties, replaster, render or fit damp courses.

If that is how you would like the work done, 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.
