The debate comes up on almost every outdoor project we work on. Here’s a straightforward look at both options — what each delivers, what each costs over time, and how to think about the decision for your specific situation.
Every spring, someone is either staining their wood deck again or noticing that their composite deck looks exactly the same as it did the day it was installed. Both of those people probably made the right choice for their situation — which is the honest starting point for this conversation. There is no universally correct answer here. There’s only what makes sense for your property, your budget, your tolerance for maintenance, and how you actually want to use the space.
Pressure-Treated and Natural Wood
Wood decking is what most homes in the Fraser Valley were built with, and for good reason. Pressure-treated lumber is widely available, affordable, and structurally proven. Natural wood species like cedar offer genuine beauty and good natural resistance to rot and insects — BC cedar in particular has been used for outdoor construction in this region for generations because it performs well here.
The trade-off is maintenance. A wood deck in our climate — where we deal with long wet winters, UV exposure in summer, and frequent freeze-thaw cycles — will need to be cleaned, dried out, and either stained or sealed on a regular basis. If you let it go, you’ll eventually be dealing with graying, checking, and in the worst case, rot.
Composite Decking
Composite decking — boards made from a blend of wood fibre and plastic — has improved dramatically over the last fifteen years. Early composites got a bad reputation for fading, staining, and getting uncomfortably hot in direct sun. The newer capped composite products from reputable manufacturers are genuinely better: more fade-resistant, less prone to staining, and more realistic-looking than first-generation materials.
The appeal is primarily the reduction in maintenance. You’re not staining it every couple of years. You’re not worrying about splinters. It won’t rot. For a deck that gets heavy use or is in a particularly exposed location, the low-maintenance argument is real. What composite doesn’t do is get cheaper — material costs are significantly higher than pressure-treated wood.
The Pros and Cons
Wood — Strengths:
- Lower upfront material cost
- Natural look and feel; BC cedar weathers beautifully with proper care
- Repairable — individual boards can be replaced
- Stays cooler in direct sun
Wood — Drawbacks:
- Requires regular staining or sealing
- Susceptible to rot if neglected
- Splinters, especially as it ages
- Can check and warp in wet climates
Composite — Strengths:
- Very low ongoing maintenance
- Won’t rot, splinter, or check
- Consistent colour and texture over time
- Good for high-use or rental properties
Composite — Drawbacks:
- Significantly higher upfront cost
- Gets hot in direct summer sun
- Doesn’t feel like natural wood
- Quality varies widely between brands
What Actually Drives the Decision
In our experience, the people who are happiest with composite are the ones who are genuinely not interested in maintenance and are willing to pay for that upfront. The people who are happiest with wood are the ones who either appreciate the natural material aesthetically, are comfortable with periodic upkeep, or are working within a tighter budget. Both groups made the right call for themselves.
One thing we always tell clients: regardless of what decking material you choose, the framing and structural components underneath matter just as much. A composite deck on a poorly built frame is still going to fail. Proper drainage, appropriate joist sizing and spacing, adequate ledger flashing, and the right hardware for your specific climate are non-negotiable regardless of what’s on the surface.
In the Fraser Valley, moisture management is the primary driver of deck longevity regardless of material. The decks we see fail early almost always have a moisture problem at the frame level, not just the surface. We build both wood and composite decks and can give you a realistic cost comparison for your specific project before you decide.
