Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects due to their durability, appearance, and reasonable cost. But how durable are quartz countertops exactly? What factors impact their longevity and performance over time? This comprehensive guide examines the durability and lifespan of quartz countertops to help homeowners decide if they are the right choice for their needs.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with polymer resins and coloring pigments. The quartz crystals make up over 90% of the material, while the resins bind it together.
Compared to natural stone countertops like granite and marble, quartz offers a more consistent appearance and texture since it is manufactured, not mined. The resins allow quartz to take on vivid colors and patterns not found in natural stone.
How Durable is Quartz Compared to Other Countertop Materials?
Quartz is one of the most durable countertop materials available today. It is harder and more scratch resistant than marble, granite, laminate, wood, and other options.
Here is how quartz stacks up against other popular countertop materials in terms of durability:
- More durable than marble and granite – Marble is prone to etching and scratching. Granite is very hard but can chip if subjected to heavy impact. Quartz stands up better to daily wear and tear.
- More durable than wood – Wood can be easily scratched, burned, or stained by water and household chemicals. Quartz is non-porous and resists most damage.
- More durable than laminate – Laminate countertops will bubble, burn, stain, scratch and peel over time. Quartz maintains its smooth surface much longer.
- Less durable than stainless steel – Stainless steel offers the highest scratch and heat resistance. But quartz provides better aesthetics for most homes.
- Similar durability to engineered wood – Materials like butcher block are very resistant to impact but can be more easily scratched than quartz.
So while stainless steel is the only material that exceeds the durability of quartz, quartz countertops are still one of the toughest kitchen countertop options available. And they offer more decoration options than stainless steel.
Factors That Impact How Long Quartz Countertops Last
Many factors affect how durable and long-lasting quartz countertops will be in your home. Consider the following when evaluating lifespan:
Quality of Installation
Proper installation by an experienced fabricator is crucial for getting the most years of use from quartz. Seams and edges should be smoothly finished. Slabs must be fully supported underneath to prevent cracks. Following the manufacturer’s instructions is vital. Poor installation techniques can lead to premature damage or failure.
Regular Cleaning and Maintenance
Simple care is required to keep quartz looking like new. Blot spills quickly to prevent stains, especially from oils, acids, and dyes. Clean with a mild soap and soft cloth. Avoid abrasive cleaners or scrubbing pads that dull the finish. Resealing is not needed, but annual application of a stone sealer adds extra protection.
Type and Frequency of Use
How you use your kitchen affects quartz durability. Occasional meal prep and cleaning will prolong its beauty versus constant daily cooking. Using cutting boards instead of slicing directly on the counter helps prevent scratches. Keeping quartz free of excess water prevents damage around sinks or dishwashers. High-traffic kitchens will show wear sooner than rarely-used surfaces.
Quality and Thickness of the Material
Higher priced quartz brands often indicate better quality materials that resist damage longer. Thicker slabs (3cm) stand up to impact better than thinner options. Inspections of the quartz surface, finish quality, and coloring consistency can identify lower grade materials prone to problems. Cheap quartz won’t endure as well as quality material.
Exposure to Impact and Heat
Quartz is very hardy, but should still be protected from excessive force or temperature extremes that can damage any stone surface. Cracking can occur if heavy pots or appliances are dropped. Dark spots or cracks develop if extremely hot pans are placed directly on the counter. Trivets and cutting boards help prevent such damage.
With proper care and maintenance, a high-quality quartz installation should easily last 15-25 years under normal residential use. Some quartz counters may remain in great shape even longer with light use.
Signs of Wear in Quartz Countertops
Quartz won’t deteriorate overnight. But gradual signs of wear can appear over time. Being aware of the following issues can help identify if your counters need repair or replacement:
- Scratches – Surface scratches develop from cutting, scraping, or dragging objects across the quartz. Most scratches are minor and merely dull the finish. Deep scratches expose the colored resins underneath.
- Chips/Cracks – Chips occur when a hard object forcefully impacts the edge of the counter. Cracks develop from an inadequate substrate or improper installation.
- Burn marks – Setting very hot pans directly on the surface can scorch or discolor quartz. These burn marks are permanent.
- Stains – Some stains may occur from spills of dark liquids. These are usually superficial and can be removed with cleaning.
- Dulling – Normal use eventually causes slight dulling of the polished finish. This is easily remedied with a quartz-safe polish but indicates age.
- Seam Separation – Normal expansion and contraction from temperature swings can cause thin cracks along seams and joints. Poor installation also contributes.
By observing your counters for these issues, you can determine if small repairs or full replacement is required to restore the look and function of your quartz surfaces.
How to Extend the Lifespan of Quartz Countertops
The simplest way to get the most years out of your quartz investment is to follow good care and maintenance habits. Here are some key tips:
- Avoid exposing quartz to excess moisture which can damage adhesive and seams. Wipe up spills immediately and keep counter areas near sinks and dishwashers thoroughly dry.
- Use cutting boards, trivets and hot pads. Never cut directly on quartz or place hot cookware on the surface.
- Clean quartz frequently with a soft cloth and mild soap. Rinse thoroughly with clean water and dry completely.
- Use only cleaners made specifically for quartz or natural stone. Avoid harsh chemicals, acidic or abrasive cleansers.
- Reseal quartz every 1-2 years with a stone-safe formula to add extra protection against staining.
- Inspect countertops periodically for any cracks, chips or dull areas and repair promptly to prevent further damage.
- Have quartz counters professionally installed by an experienced, reputable fabricator for optimal durability.
- Select high-quality quartz materials from leading brands known for strength and longevity.
Following these preventative measures will keep your quartz counters in like-new condition for many years before replacement is needed.
Average Cost to Replace Quartz Countertops
If your quartz countertops do sustain damage beyond repair or you wish to change styles, expect to pay around $80-$100 per square foot for materials and professional installation of new counters. The total cost depends on:
- Square footage – The overall size of the surface area needing replacement.
- Layout complexity – Simple squared layouts are most affordable. Angles, edges, cutouts add labor time.
- Material grade – Basic quartz counters cost $50-70 per square foot. Premium designer brands run $125+ per square foot.
- Edge profiles – Decorative edges like ogee, bevel, easing add $10-15 per linear foot.
- Removal fees – Removing old counters could cost $3-$5 per square foot if not being replaced.
- Location – Prices run higher in areas like New York City or San Francisco versus smaller towns.
Expect to pay around $3,000 to replace basic quartz counters in a small to mid-size kitchen. A larger luxury kitchen could run $10,000 or more with premium quartz.
FAQ About the Durability of Quartz Countertops
Many homeowners have additional questions about the durability and lifespan of quartz. Here are answers to some frequently asked questions:
Are quartz countertops really indestructible?
Quartz is extremely hardy and resistant to scratches, stains and heat. But no countertop material is completely indestructible. Chipping, cracking and dulling is possible over many years of heavy use. Avoiding excessive impacts and abrasion keeps quartz in great shape.
Do quartz countertops stain easily?
Quartz resists stains very well thanks to its non-porous surface. Spills are not absorbed if cleaned promptly. However, lengthy exposure to strong pigments like wine, coffee and oil can cause permanent discoloration. Quick cleanup is key.
Is it OK to cut food directly on quartz?
It’s best to use a cutting board instead of cutting directly on quartz. This prevents dulling of the surface finish over time. The occasional slicing won’t immediately damage quartz but repeated cutting leaves micro-scratches.
Can you damage quartz by placing a hot pan on it?
Excessive, prolonged heat exposure can damage quartz. Use trivets or hot pads when setting hot pots, pans or baking sheets on the counters. Very brief contact with a hot pan generally won’t harm quartz though.
How thick should quartz countertops be?
Most quartz slabs are 3/4 inch to 1 1/4 inches thick. 3cm (1 1/4 inches) provides the most durable foundation and reduces chance of cracking or warping. Thinner 2cm slabs are prone to more damage but cost less.
Do you need to seal or re-polish quartz counters?
Resealing is not required for quartz since it is non-porous. However, applying a stone sealer every 1-2 years provides added protection. occasional re-polishing also helps restore the luster as it dulls over time.
Achieving Long-Lasting Beauty and Function with Quartz Countertops
When shopping for countertops, durability is often a top concern for homeowners. Quartz provides hardy performance that can withstand years of regular use when properly maintained.
