A backyard deck is more than just a few planks of wood nailed together—it’s a place where summer BBQs happen, where you sip your morning coffee, and where the kids chase each other until sundown. But here’s the million-dollar question: How long does a wood deck last?
The answer? Well, it depends on the type of wood, how well you maintain it, and the unique weather conditions of Southwestern Ontario (which, let’s be honest, can be pretty unpredictable). Let’s break it all down so you know exactly what to expect from your deck’s lifespan.
How Long Does a Wood Deck Last?
On average, a well-maintained wood deck can last anywhere from 10 to 30 years. But that’s a big range, right? The key factors that determine lifespan include:
- Type of wood used
- Weather conditions
- Maintenance and upkeep
- Quality of installation
Now, let’s dive into the different types of wood decking and see how long they actually hold up.
How Long Does Pressure-Treated Wood Last?
If you have a deck in Southwestern Ontario, there’s a good chance it’s made of pressure-treated wood. This type of wood is chemically treated to resist rot, insects, and moisture.
Lifespan: 15 to 20 years (with proper maintenance)
To keep your pressure-treated deck looking great for two decades, you’ll need to:
-Seal it every couple of years to prevent moisture damage
-Keep it clean to avoid mildew and mold buildup
-Inspect and replace damaged boards before they cause bigger issues
Skipping maintenance? Your deck might not even make it to 10 years. So, a little effort goes a long way!
How Long Does a Cedar Deck Last?
Ah, cedar. It’s beautiful, naturally resistant to rot, and has that incredible smell. But does it last?
Lifespan: 10 to 15 years
Cedar contains natural oils that help protect it from the elements, but it still requires upkeep. If you want your cedar deck to last as long as possible:
-Apply a protective sealant to shield it from moisture
-Sweep off leaves and debris to prevent mold
-Avoid direct contact with soil (moisture is cedar’s worst enemy)
A well-cared-for cedar deck can easily outlast a pressure-treated one, making it a great investment if you prefer a natural, chemical-free option.
How Can You Make Your Deck Last Longer?
No matter what type of wood you choose, a little TLC can significantly extend its lifespan. Here’s how:
- Seal or stain your deck regularly (every 2–3 years for pressure-treated wood, every 1–2 years for cedar)
- Clean your deck at least once a year to prevent grime buildup
- Shovel off snow in winter (but be gentle—no metal shovels!)
- Fix loose nails and replace damaged boards ASAP
Is It Time to Replace Your Deck?
Even with the best care, all decks eventually wear out. Signs that your deck might be nearing the end of its life include:
- Soft or rotting wood
- Wobbly railings
- Excessive splintering
- Boards that won’t hold nails anymore
If you notice these issues, it might be time for a deck upgrade—and that’s where we come in!

Regular sealing helps protect against moisture, rot, and UV damage.
What type of wood lasts the longest for decking?
Hardwoods like Ipe can last up to 40 years, while cedar lasts around 10 to 15 years, and pressure-treated wood lasts 15-20 years with proper maintenance.
How does Southwestern Ontario’s weather affect deck lifespan?
The region’s humid summers and freezing winters can cause wood to expand, contract, and crack over time. Regular maintenance helps combat weather-related wear and tear.
Is pressure-treated wood better than cedar for decks?
