Maintenance & Upkeep: Do You Need to Seal Quartz Worktops Like Granite?

By Tudor Granite, Worktop Specialist | Updated: October 2025

Understanding the long-term care your worktop needs is vital for keeping it looking new. As part of our complete Quartz vs. Granite comparison, we're diving deep into the biggest maintenance difference: sealing.

Quartz: The Zero-Maintenance Option

This is simple: you do not need to seal quartz worktops. Ever.

Quartz is an engineered stone made of natural quartz crystals mixed with polymer resins. This manufacturing process creates a completely non-porous surface. Stains from wine, coffee, or oil cannot penetrate the material and can be easily wiped away. This is arguably the biggest selling point for quartz in busy family kitchens.

Granite: Requires Periodic Sealing

Yes, you do need to seal granite worktops.

Granite is a natural, porous stone. This means it has microscopic holes that can absorb liquids, leading to stains if not protected. At Tudor Granite, we apply a professional-grade sealant to all our granite installations, which protects the stone for several years. Over time, this sealant wears down.

You may need to reseal your granite every 3-5 years, depending on the type of granite and how heavily you use your kitchen. It's a straightforward process that you can even do yourself. Find out more in our detailed guide: Do You Need to Reseal Granite? (A Simple Test).

Conclusion

If your top priority is a "fit-and-forget" surface with the absolute minimum of upkeep, quartz is the clear winner. If you don't mind a simple sealing task every few years in exchange for the unique beauty of natural stone, then granite is still an excellent choice.
