Four details and we do the rest. No charge, no obligation.
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.
