How to Choose the Right Deck Material for Wet Canadian Summers
Orion Outdoor Living • May 20, 2026
For homeowners in London, Westmount, Komoka, Mt Brydges, and St. Thomas, Ontario, enjoying the outdoors means getting the most out of every summer day. But with the region’s famously wet spring and summer seasons, selecting the right deck material is crucial for comfort, durability, and long-term value. At Orion Outdoor Living, we understand the local climate and what it takes to create beautiful, functional decks that thrive in Ontario’s unique weather.
Why Deck Material Matters for Wet Weather
Frequent rain, humidity, and fluctuating temperatures during Canadian summers can quickly wear down traditional deck materials. While the right choice enhances your yard’s appeal and usability, the wrong material may require frequent maintenance or costly repairs. Local homeowners are increasingly searching for solutions that balance low upkeep with durability and style, making material selection a top concern.
Trending Question: What deck material is best for rainy climates?
This is one of the most searched questions in Ontario, and the answer focuses on selecting moisture-resistant, insect-repelling materials that won’t warp, rot, or become slippery after a downpour.
Comparing the Best Deck Materials for Southwestern Ontario
Composite Decking
Composite decking is engineered from a blend of wood fibers and plastic, offering impressive durability and a sleek look that complements modern outdoor spaces throughout London and surrounding communities. Its key advantages for wet summers include:
- Superior moisture resistance, minimizing the risk of warping or rotting
- Fade- and stain-resistant surfaces, ideal for heavy rains and humidity
- Minimal maintenance—no need for annual staining or sealing
- Multiple color options, from earth tones to trendy dark shades, allowing you to match your home’s aesthetic
Homeowners appreciate that Orion Outdoor Living offers premium composite decking brands like Timbertech AZEK, which features a protective cap to prevent water absorption and extend the lifespan of each board.
Pressure-Treated Wood
For those drawn to classic backyard aesthetics, pressure-treated wood remains a popular option. It undergoes a chemical process to resist moisture and insect damage, making it a solid choice for the region’s climate. However, pressure-treated wood requires diligent maintenance to stay in top shape:
- Annual or biannual sealing to guard against swelling and cracking
- Occasional sanding and refinishing after intense wet seasons
- Inspections for mold and mildew, particularly in shaded areas
If you love the look and feel of natural wood decks, Orion Outdoor Living can design and install a structure with durable, pressure-treated lumber and provide a custom maintenance plan tailored to the wet Ontario environment.
PVC Decking
PVC—short for polyvinyl chloride—decking is another high-performance, low-maintenance option. PVC is completely moisture-proof and will not absorb water, making it ideal for backyard decks that see plenty of rain or poolside splash. Other benefits include:
- Excellent resistance to mold and mildew
- No risk of splinters or rot
- Available in a wide range of colors and textures, including modern and wood-style finishes
- Lower carbon footprint with recycled content options
Local design trends are moving toward sophisticated light tones and clean lines, both easily achieved with PVC products expertly installed by Orion Outdoor Living.
Critical Decking Features for Wet Weather
When considering your new deck for May and the rest of Ontario’s rain-heavy summer, prioritize:
- Slip-resistant surfaces for safety during and after rain
- Proper drainage systems and deck layout to prevent standing water
- Durable railings and fasteners made for moisture-rich environments
- Easy-to-clean materials, so dirt and debris left behind by spring storms don’t linger
Our design team at Orion Outdoor Living ensures every project has these essentials built in for a safer, longer-lasting deck.
