Our Guarantees, Quality You Can Rely On

When you invest in new windows, doors or a conservatory, you want to know they'll continue to perform for many years to come. That's why every installation from ZEN is backed by comprehensive guarantees, giving you confidence long after the work is complete.

We believe that quality products deserve quality protection. Our guarantees are designed to give you lasting peace of mind and reflect our commitment to excellence, reliability and customer care.

A 25-Year Guarantee on Frames

We guarantee all of our aluminium products, along with our white uPVC double-glazing and conservatory frames, against bending, bowing, warping or cracking for 25 years from the date of installation.

For colour-foiled uPVC frames, this guarantee is 10 years from the date of installation.

This means you can be confident that your new frames are built to last and will continue to look and perform as they should for years to come.

10-Year Guarantee on Sealed Double-Glazing Units

One of the most common concerns with older double-glazing is condensation or misting between the panes of glass. This happens when the seal around the unit fails.

That's why we guarantee all hermetically sealed double-glazing units against internal misting for 10 years from the date of installation.

Your glazing should remain clear, energy-efficient and attractive, helping your home stay warm and comfortable throughout the seasons.

10-Year Guarantee on Hardware

The parts you use every day are just as important as the frames and glass.

All locks, hinges and moving parts supplied with your installation are guaranteed for 10 years from the date of installation. This helps ensure your windows and doors continue to open, close and lock smoothly, while providing the security and reliability you expect.

Peace of Mind, From Beginning to ZEN

At ZEN, we believe that our relationship with you doesn't end when the installation is complete. Our guarantees are part of our promise to provide quality products, expert installation and dependable aftercare.

When you choose ZEN, you're choosing a local company that stands behind its work and is committed to doing things properly. From your first enquiry to many years after your installation, we're here to give you confidence that you've made the right choice.

If you'd like to find out more about our windows, doors or conservatories, or have any questions about our guarantees, we'd be delighted to help.
