Vinyl vs Composite vs Wood Decking in the Okanagan — Which One Actually Lasts?
Vinyl, composite, or good old pressure-treated wood. For a deck that has to survive an Okanagan summer baking in the sun and an Okanagan winter of freeze and thaw, which decking material actually lasts, and which one is worth your money? Here is the straight comparison, without the sales pitch.
Pressure-treated wood
Up-front cost: lowest. This is the main reason people still choose it.
How it holds up here: wood is a natural product, and our climate is hard on it. Intense summer UV fades and dries the boards, and repeated freeze-thaw cycles work at any cracks. Without upkeep, a wood deck greys, checks, and can splinter within a few years.
Maintenance reality: to keep a wood deck looking good and lasting, plan on cleaning and re-staining or re-sealing every two to three years. That is a real, recurring cost in both money and weekends.
Best for: homeowners whose deciding factor is up-front budget, and who are genuinely willing to maintain it.
Composite decking
Up-front cost: higher than wood, usually mid-range.
What it is: a blend of wood fibres and plastic, capped on the surface for stain and fade resistance.
How it holds up here: modern capped composite resists fading, staining, and moisture well, and it does not need staining. It handles our sun and winters far better than bare wood. Lower-end uncapped composite from years past had fading issues, so the quality of the product matters.
Maintenance reality: an occasional wash. No sanding, no staining.
Best for: homeowners who want a low-maintenance deck with a wood-like look and a moderate budget.
Vinyl (PVC) decking
Up-front cost: highest of the three.
What it is: fully plastic (PVC) boards, no wood content.
How it holds up here: excellent moisture and rot resistance, holds colour well, and stays stable through freeze-thaw. Because there is no wood in it at all, there is nothing to rot. Some homeowners find it looks slightly less natural than premium composite, though modern PVC has come a long way.
Maintenance reality: the lowest of the three. A rinse now and then.
Best for: homeowners who want the longest low-maintenance lifespan and are building near water or in full exposure.
The honest way to choose
Think in terms of total cost of ownership, not just the sticker price.
- If up-front budget is the deciding factor today and you will actually maintain it, wood still makes sense.
- If you want a low-maintenance deck with a natural look and a middle budget, composite is the sweet spot for most Okanagan homes.
- If you want to build it once and essentially forget it, especially on a deck in full afternoon sun or near the lake, vinyl is worth the premium.
Over ten to fifteen years, the maintenance savings on composite and vinyl often close much of the gap with wood's lower starting price. The right answer depends on how long you plan to stay in the home and how you feel about weekend upkeep.
Frequently asked questions
Does composite decking get hot in the Okanagan sun?
All decking warms up in direct sun, and darker boards get hotter. Lighter colours and good airflow under the deck help. This is worth considering for a deck that gets full afternoon exposure or where kids and pets go barefoot.
How long does each material last?
A maintained wood deck can last a long time but needs constant upkeep. Quality composite and vinyl are typically warrantied for decades and hold up with almost no maintenance.
Can I put composite or vinyl boards on my existing deck frame?
Often yes, if the frame and footings are sound and built to the right joist spacing. A builder can assess whether your structure supports a resurface.

The bottom line
There is no single best decking material, only the best one for your budget, your exposure, and your tolerance for maintenance. Wood wins on up-front cost, vinyl wins on lifespan and lowest upkeep, and composite sits in the practical middle for most Okanagan homes. Decide how long you plan to enjoy the deck, then choose the material that fits that horizon.
