Guarantee FAQs
Straight answers
Common questions before you rely on a guarantee.
Guarantee questions answered plainly.
01How long is the guarantee?
Product and installation terms are confirmed in writing on your quote and handover pack. Durations differ by manufacturer, system and whether the job is supply-only or supplied and fitted.
02Is the guarantee insurance-backed?
For eligible domestic installation work, we arrange a 10-year QANW insurance-backed guarantee after completion. This is separate from the product and workmanship guarantees set out in your written agreement. The policy explains what is covered and when it applies.
03What if the glass mists up?
Send photographs and the job reference. Coverage depends on the sealed-unit term, cause and exclusions in your paperwork. The usual route is replacement of the affected unit after measurement.
04What about supply-only orders?
For supply-only orders, we'll confirm the product warranty in writing. Installation and any fitting guarantee are arranged with your chosen installer.
05Does finance change the guarantee?
The product guarantee and any credit agreement are separate documents. Read the confirmed guarantee and our finance information before proceeding.
