Can Heat Damage Quartz Splashbacks Or Countertops?

Within modern interior design, quartz splashbacks and countertops have surged in popularity, thanks to their aesthetics, durability, and ease of maintenance. However, an important question that many people seem to forget to consider is ‘Can heat pose a threat to the integrity of quartz installations?’

While quartz is renowned for its durability and resistance to many elements, including scratches and stains, it is not immune to heat damage. Extreme and prolonged exposure to high temperatures can indeed pose a risk to the integrity of quartz splashbacks and countertops. 

How Severely Can Heat Affect Quartz Surfaces?

Understanding the extent of the impact heat can have on quartz surfaces is crucial for homeowners and designers alike. While quartz is renowned for its durability, heat sensitivity remains a concern. The degree of damage inflicted by heat on quartz surfaces can vary depending on several factors, including the temperature of the heat source, the duration of exposure, and the specific composition of the quartz material. 

In instances of sudden, extreme heat, such as placing hot cookware directly onto the surface, quartz is susceptible to thermal shock, potentially leading to cracks, discolouration, or warping. Even prolonged exposure to moderate heat levels, such as from radiant heat sources or prolonged sunlight exposure, can gradually degrade the resin binders within the quartz, compromising its structural integrity and aesthetic appeal over time. By delving into the nuances of heat’s impact on quartz surfaces, homeowners and designers can implement proactive measures to mitigate risks and preserve the beauty and functionality of their quartz installations.

Why Does Heat Affect Quartz?

Despite being highly durable, quartz is composed of natural quartz crystals bound together with resins and pigments. When exposed to high temperatures, these resin binders can undergo thermal expansion or contraction, potentially leading to structural damage such as cracks or warping. 

Safeguarding Quartz from Heat

Preserving the integrity and beauty of quartz surfaces against heat damage requires proactive measures. Firstly, utilise heat-resistant pads or trivets to create a barrier between hot cookware and the quartz surface, preventing direct contact and minimising the risk of thermal shock. 

Avoid placing hot pots or pans directly onto the quartz, especially immediately after removing them from the stove or oven, as sudden temperature changes can compromise the material. Additionally, consider installing protective heat shields or barriers around radiant heat sources, such as stoves or grills, to minimise the exposure of quartz surfaces to high temperatures. 

Regularly clean quartz surfaces with a mild soap and water solution, avoiding abrasive cleaners or harsh chemicals that could potentially weaken the resin binders over time. 

By implementing these preventive measures and practising proper maintenance, homeowners can effectively safeguard their quartz countertops and splashbacks from heat damage, ensuring their longevity and aesthetic appeal for years to come.

How To Maintain Quartz Splashbacks & Worktops

Ensuring the longevity and pristine appearance of quartz worktops and splashbacks requires a proactive approach to maintenance. Begin by routinely cleaning surfaces with a mild soap and warm water solution, using a soft cloth or sponge to gently remove dirt, stains, and spills. 

Avoid abrasive cleaners or harsh chemicals that may scratch or dull the surface. For stubborn stains, consider using a non-abrasive cleaning agent specifically formulated for quartz surfaces. 

Regularly wipe down the surfaces with a damp cloth to prevent the buildup of grime and residue. Additionally, protect quartz surfaces from excessive heat by using trivets or heat-resistant pads under hot cookware to prevent thermal shock. Be mindful of sharp objects and avoid cutting directly on quartz surfaces to prevent scratching.

Lastly, consider sealing the quartz periodically to enhance its resistance to stains and moisture. 


While quartz boasts remarkable durability, prolonged or extreme heat can lead to cracks, discolouration, or warping, necessitating precautionary measures. By utilising heat-resistant pads, avoiding direct contact with hot cookware, and practising regular maintenance with mild cleaners, homeowners can effectively safeguard their quartz surfaces and preserve their longevity and aesthetic appeal. With a deeper understanding of heat’s impact on quartz and practical strategies for protection, homeowners can confidently enjoy the beauty and functionality of their quartz installations for years to come.
