Quartz countertops are popular options for kitchen and bathroom remodeling projects due to their durability, visual appeal, and low maintenance. However, some homeowners wonder – do quartz countertops crack? Understanding the qualities of quartz and proper care can help prevent cracks.

What is Quartz?

Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The resins bind the quartz together to create a durable, non-porous material. Quartz countertops are hard, scratch-resistant, and stain-resistant, making them excellent choices for heavy-use areas.

Benefits of Quartz Countertops:

• Durable and long-lasting
• Resists scratches, stains, heat, and moisture
• Low maintenance
• Available in a variety of colors and patterns
• Non-porous – does not require sealing

Do Quartz Countertops Crack?

With proper installation and care, quartz countertops are very unlikely to crack. Here are some key factors to understand regarding cracking in quartz:

Quartz is Flexible

Though quartz is extremely hard and durable on the surface, the resins make quartz countertops somewhat flexible overall. This flexibility prevents the material from cracking under normal use and temperature changes. Quartz can flex minimally without breaking or chipping.

Installation is Key

Most cracking occurs due to improper installation, not from the quartz material itself. Not following the manufacturer’s instructions for support, reinforcement, and seam placement can lead to tension and cracks over time. Proper installation by an experienced quartz fabricator reduces the risk of cracks.

Direct Impact Causes Cracks

While quartz resists scratches, significant direct impact force can cause chips or cracks. Dropping a heavy object on a countertop edge or corner is most likely to cause damage. However, cracks from impact are relatively uncommon.

Thermal Shock Causes Cracks

Exposing quartz to rapid, extreme temperature changes can create thermal shock leading to cracks and damage. Placing a hot pan directly from the stove or oven onto the surface can potentially cause issues over time. Using trivets and gradually cooling hot items helps prevent thermal shock.

Tension Cracks are Rare

Solid quartz countertops should not crack from normal expansion and contraction, as the material and installation allow for some movement. However, inadequate support or improper seams that limit natural movement can create enough tension to crack quartz. These types of cracks are uncommon.

Quality Impacts Durability

Higher-end quartz brands that use more quartz and less resin fillers tend to have lower crack risk. More expensive options like Silestone, Caesarstone, and Cambria investment in quality materials and processes to prevent cracks and issues. Cheaper brands may be more prone to damage.

How to Prevent Cracks in Quartz

When properly installed and cared for, quartz countertops should not crack under normal household use. Here are top tips for preventing cracks:

• Choose experienced installers – Hire professional quartz fabricators for template, cutting, edging, seaming, and installation. Follow manufacturer guidelines precisely.
• Inspect thoroughly – Carefully examine countertops at template, during install, and after completion. Look for any gaps, chips, uneven seams, or areas of tension. Address any concerns immediately before proceeding.
• Reinforce seams – Most manufacturers recommend applying mesh tape along the back seams during installation to prevent cracks. This helps hold the seam securely.
• Avoid direct heat – Always use trivets and hot pads when placing hot pots, pans, and other items from the oven or stove onto the quartz. Allow gradual cooling first. Prevent sudden temperature changes.
• Use cutting boards – Cutting food directly on the counter can dull knives over time, leading to excessive force and potential cracks or chips. Always use a cutting board.
• Clean spills promptly – Thoroughly clean all spills, especially oils and acids. Allowing spills to sit can stain and potentially damage the surface over time if not addressed.
• Inspect for damage – Periodically inspect countertops closely for any hairline cracks or chips developing, especially around heavy use areas like the sink and stove. Fix minor issues early before major cracks occur.

What to Do if a Crack Develops

If you do notice a crack in your quartz countertop, address it right away. Here are the steps to take:

• Stop using the area – Prevent further damage by avoiding use of the cracked section until repaired. Do not place anything on or near the crack that could worsen it.
• Contact the manufacturer – Most major quartz brands provide limited warranties of 10-15 years. Reach out to the manufacturer to determine if they will repair or replace the damaged section under warranty.
• Consult a pro – If not covered by warranty, hire a professional quartz fabricator to evaluate the damage and recommend solutions. Some minor chips and cracks can potentially be repaired through expert filling.
• Consider a replacement – For major cracks or structural damage, a replacement of that section of countertop may be required. Professionals can cut out and install a new quartz piece.
• Learn from it – Analyze what may have caused the crack, such as impact force, thermal shock, or inadequate support. Take steps to prevent damage in other areas.
