How to Determine Good Quartz Countertops

Check the Brand

Not all quartz is created equal. There are only a handful of major manufacturers of engineered quartz slabs in the world. These include brands like Caesarstone, Cambria, Silestone, and LG Viatera. Opting for a premium brand ensures you’re getting a high-quality and consistent product. Lesser known or “generic” quartz brands may be prone to more variation in color, finish, and overall durability.

Examine the Pattern & Color Consistency

Take a close look at the quartz slab and check that the pattern and coloring are consistent all the way through. High-quality quartz has uniform specks and veins. Lower quality versions can have blotchiness or obvious color variations. Examine slabs from the same batch to confirm they have a consistent appearance.

Feel for the Finish

Run your hand across the surface of the quartz. Higher quality quartz will have a smooth, glossy finish. Lower quality may feel a bit rougher or have visible pits or scratches. A glossy finish is also easier to keep clean.

Check Thickness

Quartz slabs typically come in 3/4 inch and 1 1/4 inch thicknesses. While thinner versions may save on cost, the thicker slab is more durable and resistant to cracks or damage over time. Go with the thicker option especially for high traffic areas like kitchen counters.

Confirm It’s Non-Porous

Quartz is prized for being non-porous and not requiring sealing like natural stone. To check, splash a few drops of water on the surface. It should bead and not absorb. This non-porous nature makes quartz resistant to stains and microbes.

Opt for Pure Natural Quartz

Some low-end quartz uses crushed stone and polymers as filler. Pure natural quartz will be comprised of over 90% ground quartz aggregate combined with resins and pigments. Higher quartz content means enhanced durability and scratch resistance.

Examine Warranty Coverage

Quality manufacturers will stand behind their product with a solid warranty. Look for at least a 10-year warranty. Coverage should include defects in fabrication and materials. Some warranties may exclude minor issues like slight color variances.

Read Reviews on Installers

A top-notch quartz brand means little if it’s poorly installed. Read reviews and ask around to find the most reputable local countertop installers. An experienced installer is key to getting a beautiful, seamless countertop that will last.

Ask About Maintenance Needs

While quartz requires little maintenance, you’ll still need to take care of it properly. Confirm what cleaning products are safe for the surface. You’ll also need to reseal quartz every 1-2 years. Ask about any special care instructions.

By carefully examining the quartz and supplier, you can feel confident you’re investing in a high-quality countertop. Taking the time to check brands, durability, warranties, and installer reputation will ensure you wind up with a beautiful, long-lasting quartz countertop. With a bit of due diligence, you can enjoy worry-free style and function.
