White PVC frames and sashes, sealed units and hardware are covered for 25 years. Coloured PVC windows are covered for 15 years.

The coverage is non-prorated, so year twenty is protected on the same terms as year one, and it transfers to the next owner when the stated registration and transfer conditions are met. If something needs attention later, submit a service request and our team reviews it directly. See the full warranty for exclusions and labour terms.

Your installation is carried out by Norden Seal's own in-house team. From the first measurement through to the final walkthrough, the team takes careful measurements, explains the agreed scope before work starts and completes the installation with attention to fit, finish and the rest of your home. You have one team to contact before, during and after the work, and one team accountable for the result.

You do not need to book a sales visit to find out what a window costs. Norden Seal publishes price ranges by window type and city, and a price calculator you can run yourself, so you can check the numbers before anyone comes to your home and compare them against any other quote you receive. Pair that with energy-efficient window and door options and a process that is spelled out from consultation to installation, and you can make the decision with the facts in front of you.
