Quartz Countertops Explained: Why They Don’t Need Sealing (and How to Care for Them)

August 27, 2025

Quartz countertops stand out as one of the most low-maintenance and reliable options for modern homes. Because quartz is engineered to be non-porous, it naturally resists stains, spills, and bacteria without the need for sealing. This durability pairs with wide design flexibility, making quartz a smart choice for kitchens, bathrooms, and beyond. At Design Surfaces, we guide Cleveland homeowners, designers, and contractors in comparing quartz with granite, marble, and quartzite. With full slab viewing available in our showroom, you can experience how quartz delivers both style and long-term performance.

What Makes Quartz Countertops Different

Quartz countertops are engineered stone surfaces, typically made of 90 to 94 percent natural quartz crystals bound with resins and pigments. This blend creates a material that looks like natural stone but performs with greater consistency and durability.

Why it matters:

  • Natural stone such as granite or marble contains tiny pores that can absorb liquid, which is why sealing is required
  • Quartz eliminates this issue entirely (It is non-porous from the start, meaning liquids, oils, and bacteria cannot penetrate the surface)

For busy kitchens, bathrooms, and laundry rooms, quartz offers both peace of mind and lasting beauty.

Benefits of Quartz Countertops (Beyond No Sealing Required)

1. Non-Porous Protection

Quartz naturally resists stains from wine, coffee, oils, and juice. Cleanup is as simple as wiping with soap and water.

2. Everyday Durability

Ranking 7 on the Mohs hardness scale, quartz resists scratches, chips, and everyday wear better than many natural stones.

3. Hygienic Surface

Because there are no pores, quartz does not harbor bacteria, mold, or mildew, making it especially safe for kitchens and baths.

4. Low Maintenance

No sealing, no special products, no recurring maintenance appointments. Just simple cleaning.

5. Consistent Appearance

Unlike natural stone, quartz offers uniform colors and patterns across slabs, ideal for open-concept kitchens or large islands.

6. Wide Design Range

Quartz can mimic marble, deliver bold solid colors, or feature subtle veining. Whether you prefer timeless whites or striking modern tones, there is a quartz design to match your style.

How to Care for Quartz Countertops

Quartz is one of the easiest surfaces to maintain, but a few simple practices will protect your investment:

  • Daily Cleaning – Use warm water, a mild dish soap, and a soft cloth
  • Avoid Harsh Chemicals – Skip bleach, oven cleaners, or abrasive powders that can damage resins
  • Heat Protection – While resistant to moderate heat, quartz is not heat-proof. Always use trivets or hot pads
  • Use Cutting Boards – Avoid cutting directly on the surface to prevent scratches and protect your knives

With these habits, your quartz countertops will look brand new for decades.
