Our 25-year cavity wall insulation guarantee is independently backed by the IAA.
25-year cavity wall insulation guarantee
After the installation
If you have any concerns about your cavity wall insulation after the work has been completed, please contact us as soon as possible (ideally, in writing for your own records), and we will rectify any defects free of charge.
If you are still not satisfied with the work we have carried out for you, you can contact the IAA, the independent guarantee provider, who will investigate your concerns free of charge.
Terms of the guarantee
The 25-year guarantee applies only to the areas where we have installed cavity wall insulation for you.
- The property must be fully maintained following the installation.
- Any post-installation recommendations listed within the survey report or by the surveyor must be completed and evidence of completion must be retained.
- The guarantee will be invalidated if the installation has been subject to misuse or negligence, or if it has been altered, repaired, modified, tampered with or disturbed after the installation was completed.
The full details of the terms will be listed on the guarantee.
Important: For previous owners of an existing, unexpired 25-year CIGA guarantee who have had building, refurbishment or amendment works completed at their property, which have directly impacted the effectiveness of the old insulation material, will not be eligible for a renewed IAA guarantee even if we fully carry out your works. However, Viridian will arrange an alternative insurance backed 25-year guarantee for you.
