All of our window and door profiles are covered by a ten year guarantee against manufacturing defects. Your installer will offer a guarantee on the installation. Make sure that this guarantee is “insurance-backed” and offered by a DTI approved insurer. This means that if the installer goes out of business – for any reason – you are still covered.
Most guarantees will cover defects in materials and workmanship, but always check the small print. If there is anything you’re not happy with, check it out before you sign on any dotted lines.
