Government research has shown that problems associated with cavity wall insulation are very few and and when they do occur, they can usually be easily rectified by your installing company. First though check that there is no obvious cause for your problem, for example blocked gutters or earth piled up against your walls.

If you still feel that the problem is due to the installation, then you should contact the installer, who will inspect and remedy the problem where possible. If the installer is unable to solve the problem, then contact CIGA in writing, stating the problem and the steps you have taken to have the matter resolved.

CIGA will then arrange to investigate the complaint, and where neccessary, ensure that the appropriate remedial work is carried out free of charge. Each Guarantee certificate has a unique number that should be quoted on all correspondence.
