Five Service Commitments a Window Warranty Card Must State Clearly
A warranty is only worth its enforcement. Five commitments must be quantified on the card: scope, term, response, spare parts and transferability — plus how to file a claim properly.
Every salesperson says 'ten-year warranty'. But a warranty is worth its enforcement, not its years: does it cover hardware? How fast is the response? What happens when the model is discontinued? Nobody asks until something fails — and then each item costs money. Here are five commitments that must be quantified on a warranty card, together with how we execute them; our customers are welcome to check us against this article.
1. Scope, split by part class. Structural parts (profiles, glass, welded corners) versus consumables (gaskets, hardware, handles, rollers). A sound card gives structural parts a long term — profiles ten-plus years, insulated-glass fogging ten years — and a shorter separate term for consumables. Beware both extremes: 'ten years on everything' with fine print excluding all consumables, or no scope stated at all, which means the seller holds all interpretation.
2. Start date and evidence. The warranty runs from the acceptance signature date, not production or mid-installation. Keep the stamped acceptance form and warranty card; photograph them and file them with your renovation documents.
3. Quantified response. 'Prompt response' is not a commitment. 'Response within 24 hours, on-site within 48, resolved within 72' is. Response times decide the experience of urgent problems — rain leaks do not wait for a convenient slot.
4. Spares and discontinuation. Product lines iterate every two to three years while windows last fifteen. A responsible card commits to supplying hardware, gaskets and glass spares — or approved equivalents — for at least ten years after a model is discontinued. Without it, a worn roller in year ten can force a whole-window replacement. Ours states spare availability of no less than ten years.
5. Transferability. With second-hand transactions common, the warranty should follow the property, not the person — the new owner continues the remaining term with the original acceptance evidence.
Filing a claim properly doubles the speed: describe symptom plus location plus purchase date ('bought March 2024, master bedroom south window, seepage at lower-left during rain' beats 'window leaks'); for leaks, film the event during rain — dry traces are the hardest to diagnose; dry the water but do not apply your own sealant, which hides the original path; and for high-floor exterior work, confirm the property office's rules first.
An industry truth: the expensive half of after-sales is diagnosis, not repair. That is why response and resolution times matter more than the headline number of years — the years are paper; the times are experience.
