HomePro Insurance

A HomePro Insurance Backed Guarantee, or IBG for short, covers deposits (where the level of cover is Value Plus or TrustMark Value Plus), workmanship and materials. Deposit Protection Cover lasts for 120 days from the date of payment to the contractor and the Warranty Insurance Policy is valid for a period of up to 10 years. Clement are pleased to be able to offer a Home Pro Insurance Backed Guarantee to the majority of home owners when purchasing our products.

*HOMEPRO insurance cover and COVID-19 – In line with many insurers HomePro have carried out a review of their policies following the outbreak of COVID-19 and they have informed all of their customers including the Clement Windows Group that due to the perceived risks associated with it they are ceasing the immediate and automatic guarantee of deposits paid by customers to companies. They are however continuing to offer full coverage of the completed and fully paid project costs. We would emphasise this has absolutely nothing to do with their view on the Clement Windows Group and we wish to reassure customers of the strength of our balance sheet and that this should not impact any work undertaken by us. As stated above HomePro have confirmed that they will continue to provide cover for the completed job and the insurance guarantee will be activated upon completion.
