Decking material selection is one of the most important decisions you'll make for your Muskoka or Georgian Bay property. Each option comes with trade-offs between cost, maintenance, appearance, and longevity in cottage country conditions.
Cedar: The traditional choice for Muskoka decks. Cedar naturally resists moisture and insects, holds up well in freeze-thaw cycles, and develops a beautiful silver-grey patina over time. It requires periodic sealing or staining to extend its life but remains one of the most aesthetically fitting materials for cottage environments.
Pressure-treated wood: The most affordable decking option. Modern pressure-treated wood is safe and durable but requires regular maintenance to prevent cracking and greying. Best suited for ground-level decks or as structural framing beneath a premium decking surface.
Composite decking: Made from a blend of wood fibre and plastic, composite decking offers excellent resistance to moisture, UV rays, and insects. It requires virtually no maintenance beyond occasional cleaning. The upfront cost is higher than wood, but the long-term savings in maintenance often make it the better investment for seasonal properties.
PVC decking: Fully synthetic and the most durable option available. PVC decking will not warp, crack, or splinter and requires minimal upkeep. Ideal for waterfront properties exposed to constant moisture and sun.
In most Muskoka municipalities, a building permit is required for decks that are attached to the house, elevated more than 600mm above grade, or exceed a certain square footage. Permit requirements also apply to docks and shoreline structures, which are subject to additional approvals through Conservation Authorities and the Ministry of Natural Resources. A reputable deck builder will manage the permit process on your behalf and ensure all work complies with local bylaws and setback requirements.
