How Long Does Quartz Countertop Last?

Quartz countertops have become increasingly popular in recent years due to their durability, low maintenance, and stylish appearance. Many homeowners wonder how long their investment in quartz will last. Here is a detailed overview of the expected lifespan of quartz countertops and what factors impact their longevity.

What is Quartz?

Quartz is an engineered stone made from crushed quartz crystals combined with polymer resins and pigments. It is molded into slabs and hardened to create a material that resembles natural stone but has increased durability.

Key properties of quartz:

  • Non-porous – repels stains and resists scratches
  • Does not require sealing
  • Heat, stain, scratch, and scorch resistant
  • Available in a wide range of colors and patterns
  • Lower maintenance than natural stone
  • Durable and long-lasting

Expected Lifespan of Quartz Countertops

With proper care and maintenance, quartz countertops can last 15 to 25 years or longer. Many manufacturers provide a 10-15 year warranty on quartz counters. This lifespan exceeds that of many other countertop materials.

Here are the key factors that determine the longevity of quartz:

Quality of Installation

Proper installation by an experienced professional ensures quartz counters fit seamlessly with no uneven joints or gaps. This prevents moisture and debris from seeping underneath and causing damage. Poor installation can undermine the structural integrity of the counters.

Usage and Maintenance

How you use and care for your quartz counters impacts their longevity. Quartz’s durable surface can withstand normal wear and tear. But cutting or placing hot items directly on the surface leads to accidental damage. With routine care like wiping spills immediately and using cutting boards, quartz can remain in excellent condition for over two decades.

Sunlight Exposure

Over years of use, sunlight can cause subtle changes in the color and appearance of quartz counters. Placing counters out of direct sunlight prevents severe fading or discoloration.

Quality of the Product

Higher priced quartz made from pure crystalline quartz tends to be more durable than economy brands blended with resins and fillers. Opting for quartz from a reputable manufacturer ensures ideal hardness and resilience.

Maintenance Tips for Long-Lasting Quartz

Simple maintenance goes a long way in extending the life of your quartz countertops. Follow these best practices:

  • Use cutting boards and hot pads to prevent scratching and scorching.
  • Clean spills promptly using a mild detergent and soft cloth.
  • Avoid using abrasive cleaners or scouring pads.
  • Rinse the surface after cleaning to remove residue.
  • Reseal joints every 1-2 years using a clear silicone-based caulk.
  • Inspect countertops periodically to detect separations or cracks needing repair.
  • Avoid sitting or placing heavy loads on countertops for extended time periods.
  • Have countertops professionally refinished as needed to restore their polished surface.

Signs You May Need New Quartz Countertops

Over two decades of use, quartz counters may show signs of wear indicating a need for replacement. Look for:

  • Severe scratches, cracks, chips or gouges that cannot be repaired.
  • Permanent heat or scorch marks.
  • Sections detaching from the substrate causing gaps.
  • Consistent buildup of hard water marks or stains.
  • Fading, discoloration or cloudiness of the finish.
  • Warping or separation of joints causing leaks.

Renewing Your Quartz Countertops

If your quartz counters show their age after prolonged use, you have options to upgrade without replacing your entire counter:

  • Resurfacing – Professionally sanding down and refinishing the top layers of your quartz can restore its smooth surface and color. This costs a fraction of new counters.
  • Overlay – Installing a new thinner quartz overlay over your existing counters provides an affordable facelift.
  • Partial Replacements – Only replacing sections of quartz that are damaged beyond repair reduces costs.

With proper installation and care, your investment in beautiful quartz counters can last over two decades. Simple maintenance and prompt repairs extend their lifespan. Know the signs of aging counters needing replacement or renewal. With various renewal options available, quartz offers lasting style and function.

Frequently Asked Questions

How long do quartz countertops last compared to other materials?

Quartz typically lasts longer than solid surface, laminate, tile, and wood counters which have an average lifespan of 10-15 years. Natural stone may last as long as quartz with proper sealing and care.

Do scratches and chips affect the durability of quartz?

Minor scratches do not impact the structural integrity of quartz. But deep gouges should be repaired to prevent cracking or separation over time.

Does quartz need to be resealed over time?

No, quartz resists stains without needing periodic resealing required for natural stone counters. However, silicon-based caulk should be reapplied every 1-2 years to seal joints.

Can faded or discolored quartz be restored?

Yes, professional resurfacing can remove stains and restore the color and finish of aged quartz countertops.

Is it worthwhile to replace only portions of damaged quartz?

Replacing sections of damaged quartz rather than the whole counter is cost-effective if damage is limited to high wear areas like near the sink.


With an expected lifespan of 15-25 years, quartz counters are built to last with minimal maintenance. Simple care like using cutting boards, wiping spills, and avoiding scorching optimizes their longevity. Periodic inspection, prompt repairs, and professional refinishing restores quartz’s durable beauty. Knowing when to repair or replace sections allows you to enjoy quartz’s unparalleled performance for decades.
