When the summer temperatures rise, many homeowners begin to wonder whether the heat could affect their kitchen worktops. It's a common question, especially if you've invested in beautiful quartz, granite or Dekton worktops and want to keep them looking their best for years to come.
The good news is that high-quality stone worktops are designed to cope with everyday life. However, there are a few simple precautions worth taking during periods of hot weather to protect your investment.
In this guide, we'll answer some of the most common questions homeowners ask about caring for stone worktops during the summer months.
Can hot weather damage quartz worktops?
Quartz worktops are incredibly durable and perform exceptionally well in normal household conditions, even during a hot British summer.
However, quartz is an engineered material containing natural quartz and specialist resins. While everyday summer temperatures won't cause damage, exposing the surface to extreme heat—such as placing a hot barbecue tray, cast iron pan or oven dish directly onto the worktop—can potentially cause thermal shock or discolouration.
The simple solution is to always use a heatproof mat or trivet when placing hot cookware onto your worktops.
Can granite worktops expand in hot weather?
Granite is a natural stone formed under extreme heat and pressure over millions of years. As a result, it is exceptionally heat resistant and is one of the most durable materials available for kitchen worktops.
Although all materials expand slightly as temperatures increase, the tiny amount of expansion experienced by granite during normal summer weather is insignificant and won't affect your kitchen.
Professionally installed granite worktops are designed with these natural characteristics in mind.
Are stone worktops heat resistant?
Yes.
Quartz, granite and Dekton all offer excellent heat resistance, but each material performs slightly differently.
Granite offers outstanding natural heat resistance.
Quartz performs extremely well but should be protected from direct contact with very hot cookware.
Dekton is one of the most heat-resistant worktop materials available, making it an excellent choice for busy kitchens and even outdoor cooking areas.
Regardless of the material you choose, using trivets and heatproof mats is always recommended to help preserve the finish.
Can sunlight damage kitchen worktops?
Most indoor kitchens won't experience any problems from natural sunlight.
Granite is a natural stone and is highly resistant to UV light, while Dekton has excellent UV stability and is suitable for both indoor and outdoor kitchens.
Quartz worktops are generally intended for indoor use and prolonged exposure to strong direct sunlight over many years may affect certain colours. If you're considering an outdoor kitchen, it's worth discussing the most suitable material with an experienced supplier.
Looking after your worktops during the summer
Warm weather often means more cooking, entertaining and family gatherings, so your kitchen worktops naturally see more use.
Fortunately, caring for stone worktops is straightforward.
We recommend:
Wiping away spills promptly.
Cleaning with warm water and a soft cloth.
Using chopping boards for food preparation.
Placing hot pans on heatproof mats.
Avoiding harsh or abrasive cleaning products.
Following any care advice provided when your worktops are installed.
These simple habits will help your worktops remain beautiful for many years.
What about outdoor kitchens?
Outdoor kitchens have become increasingly popular in recent years.
If you're designing an outdoor entertaining space, choosing the right worktop material is particularly important.
Dekton is one of the leading choices for outdoor kitchens because it's resistant to UV light, heat, scratches and moisture.
Granite is also an excellent option thanks to its natural durability.
If you're planning an outdoor kitchen, Seven Seas can help you choose the most suitable material for your project.
Can I put hot BBQ trays straight onto my worktop?
This is one of the most common questions we receive during the summer.
Although granite and Dekton are highly heat resistant, and quartz is extremely durable, we always recommend placing hot barbecue trays, roasting tins and cookware onto a suitable heatproof mat rather than directly onto the worktop.
It's a simple precaution that helps protect your investment and maintain the appearance of the surface.
Which worktop is best for a busy family kitchen?
Every home is different, but all three materials offer excellent performance.
Quartz is ideal if you want a low-maintenance surface with consistent colours and patterns.
Granite offers timeless natural beauty and exceptional durability.
Dekton combines outstanding heat resistance with impressive scratch and stain resistance, making it a fantastic choice for modern family kitchens.
