Winterize Your Outdoor Kitchen: Stone Maintenance Tips for Ontario Homes

For homeowners with beautiful outdoor kitchens and stone features, this is the season that signals it's time to protect your investment from the approaching winter. At Classic Granite and Marble Inc, we know how Ontario’s freeze-thaw cycles, snow, and ice can impact granite, quartz, and other outdoor surfaces. Read on for expert guidance to keep your outdoor countertops, fire tables, and entertaining spaces looking their best for years to come.


Why Is Winterizing Outdoor Stone Important in Ontario?


Ontario’s climate is famously unpredictable, with heavy snowfall, rain, and repeated freezing and thawing. These conditions can cause natural stone to crack, stain, or lose its lustre if not properly protected. By winterizing your outdoor kitchen, you’ll avoid expensive repairs come spring and preserve the value of your property.


People Also Ask: Can you leave granite countertops outside in winter?


Yes, you can leave granite countertops outdoors year-round, but proper care is essential. Granite is highly durable, but moisture penetration from snow and ice—especially if the surface isn’t sealed—can lead to cracking or staining during freeze-thaw cycles. This underscores the importance of annual maintenance.


Essential Stone Maintenance Steps for November


Before winter’s chill takes over, follow these locally tailored steps to winterize your outdoor kitchen:


1. Clean Surfaces Thoroughly

Remove dirt, food residue, and debris before sealing. Use a gentle, pH-neutral stone cleaner—avoid harsh chemicals that can erode stone surfaces or break down sealants.


  • Sweep off leaves and debris.
  • Wash with mild soap and water or a recommended stone cleaner.
  • Rinse thoroughly and allow the surface to dry completely.


2. Inspect for Damage or Stains

Check for chips, cracks, or stains, especially around high-use areas like grills and sinks. Address repairs now—water can seep into cracks and worsen during winter’s freeze-thaw cycles.


3. Apply a High-Quality Sealer

Sealing is the key to durability for granite and other porous stones. For outdoor kitchens in London, Sarnia, Kitchener, and the surrounding Ontario areas, resealing annually—ideally each fall—protects against moisture and stains. Marble and lighter stones may need even closer care.


  • Select a penetrating, weather-resistant sealer suitable for your specific stone.
  • Apply as directed, typically in two thin coats.
  • Wipe off excess and allow to cure fully before covering or using the surface again.


4. Protect Your Counters and Appliances

Cover outdoor kitchen features to shield them from snow and ice. Use breathable, waterproof covers to prevent condensation.


  • Cover countertops, sinks, grills, and built-in storage.
  • Store smaller items, like portable grills or utensils, indoors for the season.
  • If possible, turn off and drain outdoor plumbing to avoid freezing.


5. Maintain Fire Features Safely

If your outdoor kitchen includes a custom granite fire table or stone-clad fire pit, ensure it’s protected for winter:


  • Clear out ashes and debris.
  • Check that gas lines are properly shut off.
  • Cover fire features securely.


Benefits of Proactive Stone Maintenance


By investing a little time now, you’ll gain peace of mind knowing your outdoor space will be ready for spring entertaining. Additional benefits include:


  • Extended lifespan of surfaces
  • Reduced risk of costly repairs
  • Improved property value and curb appeal
  • A head start on spring cleaning
