There are very few products in the home improvement industry offering anything more than a 10-year guarantee. For many customers, a peace of mind warranty is important to them. Firstly, the purchase of an expensive folding for sliding door is a significant financial investment.
Secondly, the window industry reputation is unfairly tarnished by a small number of window companies carrying out shoddy work, lost deposits and businesses going into administration before work is complete. The consumer is expected to part with their money before they even see a window or a door.
Bifolding and sliding door warranties can be complicated.

Air folding and sliding doors come with an industry leading 25-year manufacturer warranty.
It is also worth considering that all the components that go into making a quality bifolding or sliding door do not come from a single source. Aluminium, colouring, gaskets, glass, locks and seals all come from different manufacturers and suppliers, not just one. These suppliers also have their warranties. Glass or integral blinds may only have a five-year warranty. Locks and handles that come from these specialist hardware manufacturers do not have an extended warranty, yet the window industry provides an expected ten years.
Some homeowners remain sceptical of extended warranties aware they may have exclusions, limitations or only apply to the purchaser of the doors, not the new owner of the property.
Then there is the issue of understanding how industry bodies and associations work, set up to provide consumer protection should things go wrong. It is usually the manufacturing and installation process that compromises a product, rather than the product itself. From the design stage, all modern door and window systems are developed by expert aluminium systems houses, extensively tested and accredited before they hit the market.
All the people, processes, manufacturing and administration that goes into creating a new bifolding or sliding door enables customers to enjoy peace of mind warranties. Some companies, however, go the extra mile.
