Composite decking is the balanced choice for most Ottawa decks with good airflow and drainage, while PVC is the stronger performer wherever moisture is heavy: under snow buildup, in shaded yards, and around hot tubs. PVC costs more upfront but lasts longer with less maintenance. Luxury Decking installs both, backed by a 5-year labour warranty on every build.
Composite decking is made from a blend of wood fibres and recycled plastics, designed to reduce maintenance and improve durability. PVC decking is made entirely from synthetic polymers, offering high moisture resistance and long-term stability. Both are popular low-maintenance options, but they are not the same, and in Ottawa the differences matter. Our climate delivers 60+ freeze-thaw cycles a year, heavy spring melt, and big summer temperature swings, so moisture exposure and long-term expectations should drive the choice. This guide compares composite and PVC decking in real-world Ottawa conditions so you can make an informed decision. Last updated: July 2026.
Both materials resist rot and insects, require far less maintenance than wood, offer a consistent appearance, and are designed for long-term outdoor use. That is why they dominate premium deck builds in Ottawa. Where they differ is how they handle moisture, temperature, and time, and those three factors decide which one belongs on your deck.
PVC does not absorb moisture at all; composite contains organic wood fibre and can absorb small amounts. Moisture is one of the biggest stressors on any Ottawa deck. Snow sits on deck surfaces for months, spring melt saturates everything, and repeated freeze-thaw cycles punish any material that takes on water. Because PVC is fully synthetic it stays highly stable in wet conditions. Composite performs well too, but quality varies by manufacturer, which is why Luxury Decking installs only capped composite from Fiberon, TimberTech, and Eva-Last. The practical rule from our build experience: for areas with heavy snow buildup or limited airflow under the deck, PVC often performs better long-term.
Neither material is better here; installation quality matters most. Ottawa's temperature swings cause every decking material to expand and contract. Composite expands and contracts moderately and requires careful spacing and fastening. PVC expands more with heat and requires precise installation techniques. A crew that follows the manufacturer's gapping and fastening specifications will get decades of flat, quiet performance from either board. A crew that does not will produce lifted ends and squeaks in either material.
Usually the opposite. Modern PVC decking is often engineered with cool-to-touch technology that dissipates heat faster than wood-based composites, making it a more comfortable choice for south-facing Ottawa yards. PVC also comes in lighter colours that retain less heat, and it holds a more uniform appearance across the surface. If your deck bakes in full sun through July and August, a light PVC board is the barefoot-friendly option.
Both materials are considered low-maintenance, but not maintenance-free. Composite needs occasional cleaning, and some products may fade slightly over time. PVC needs minimal cleaning and has excellent colour stability. Neither ever needs staining, sanding, or sealing, which is the ongoing cost and weekend labour that pushes many Ottawa homeowners away from wood in the first place. Budget a wash once or twice a season for either material and you are done.
In Luxury Decking's published packages, composite starts at the Gold tier: a 12x12 Gold deck is $7,495, built with Fiberon GoodLife, TimberTech Prime, or Eva-Last Infinity boards carrying a 25 to 30 year material warranty. Premium PVC and top composite lines arrive at the Platinum tier: a 12x12 Platinum deck is $12,495 with Fiberon Sanctuary, TimberTech Terrain, or Woodbridge PVC on dug cement footings. The Diamond tier tops the range: a 12x12 Diamond deck is $15,495 with Fiberon Concord, Paramount, or Promenade, TimberTech Reserve, or Azek Landmark boards on helical piles, with LED lighting and the 10-year extended labour warranty included. All prices are plus HST and quoted without railings. Per square foot, our packages work out to roughly $50 to $52 for Gold composite, $80 to $87 for Platinum, and $99 to $108 for Diamond. The full 6-size, 4-tier price list is published on our pricing page and broken down in the Ottawa Deck Cost 2026 guide.
Upfront, PVC costs more than composite. Over the life of the deck the gap narrows: PVC often lasts longer, requires less maintenance, and performs better in wet environments. That makes lifetime cost, not sticker price, the number worth comparing.
Choose composite if you want a balance of cost and performance, your deck has good airflow and drainage, and you are comfortable with light maintenance. It is the right call for most standard residential decks in Ottawa.
Choose PVC if you want maximum longevity, your deck sees heavy moisture exposure, or you want the lowest maintenance possible. It is the right call for shaded lots, snow-loaded surfaces, hot tub surrounds, and homeowners who never want to think about their deck again.
There is no universal best, only the best fit for your property, your sun exposure, and your plans. Our materials guide compares wood, composite, and PVC side by side if you are still weighing all three.
Even the best decking material will not perform well if the structure beneath it is compromised. Undersized framing, poor drainage, and skipped manufacturer guidelines are the three failure points we see most often on decks built before we arrive. Ottawa's 4-foot frost depth makes the foundation decision especially important, which is why our upper tiers move from deck blocks to dug cement footings and helical piles. Material choice and construction quality go hand in hand; see how long decks last in Ottawa for what proper structure adds to lifespan.
Which is better for Ottawa: composite or PVC decking? Both perform well in Ottawa. PVC is superior for high-moisture areas, such as under snow buildup, in shaded yards, or near hot tubs, because it contains zero organic material. Composite is a great balanced choice for standard residential decks with good drainage and airflow.
Does PVC decking get hotter than composite in the sun? No, usually the opposite. Modern PVC decking is often engineered with cool-to-touch technology that dissipates heat faster than wood-based composites, making it a more comfortable choice for south-facing Ottawa yards. Lighter PVC colours retain even less heat.
Is PVC decking more expensive than composite? Yes, upfront. In Luxury Decking's published packages a 12x12 composite deck (Gold tier) is $7,495, while a 12x12 build with premium PVC or top composite starts at $12,495 (Platinum) and $15,495 (Diamond), plus HST, without railings. PVC typically lasts longer and needs less maintenance, so the lifetime cost gap is smaller than the sticker gap.
What composite and PVC brands does Luxury Decking install? Gold tier composite is Fiberon GoodLife, TimberTech Prime, or Eva-Last Infinity. Platinum tier is Fiberon Sanctuary, TimberTech Terrain, or Woodbridge PVC. Diamond tier is Fiberon Concord, Paramount, or Promenade, TimberTech Reserve, or Azek Landmark.
How much maintenance do composite and PVC decks need? Both are low-maintenance but not maintenance-free. Composite needs occasional cleaning and some products may fade slightly over time. PVC needs minimal cleaning and has excellent colour stability. Neither ever needs staining, sanding, or sealing.
What warranty covers a composite or PVC deck from Luxury Decking? Every build includes a 5-year labour warranty as standard. A 10-year extended labour warranty is available on any tier and included with the Diamond package. Manufacturer material warranties run separately, for example 25 to 30 years on Gold-tier composite boards.
