How much for a 600 sq ft composite deck in Vancouver?

A 600 sq ft composite deck in Metro Vancouver typically costs $33,000-$60,000 installed, depending on the composite brand, railing style, site conditions, and whether it's ground-level or elevated.

Breaking down the cost factors: Premium composite lines like TimberTech AZEK (full PVC) and Trex Transcend run $55-$100 per square foot installed, while mid-grade composites like Trex Enhance or TimberTech Edge fall in the $45-$75 range. The wide price range reflects significant differences in material quality, warranty coverage (25-50 years), and fade/stain resistance. Higher-end composites have deeper grain patterns, better colour retention, and superior scratch resistance.

Metro Vancouver's marine climate makes composite decking an excellent investment despite the higher upfront cost. With over 1,200mm of annual rainfall and 60-80% humidity year-round, composite eliminates the annual staining and sealing that cedar requires. You'll save $800-$1,500 annually on maintenance compared to a cedar deck of the same size. Composite also resists the mould and mildew growth that plagues wood decking in our damp climate.

Additional costs to budget for include building permits ($200-$800 if over 2 feet high), old deck removal ($2,000-$5,000 for 600 sq ft), and upgrades like glass railing ($150-$350 per linear foot), pergola addition ($5,000-$20,000), or integrated LED lighting ($1,000-$4,000). Elevated decks cost 30-50% more due to engineering requirements and additional structural hardware.

Site conditions significantly impact pricing. Ground-level decks on flat lots represent the lower end of the range, while second-storey decks, sloped sites (common in North Vancouver, West Vancouver, and Burnaby), or waterfront properties requiring stainless steel hardware push costs higher. Strata properties may require engineered drawings and alteration agreements, adding $500-$2,000.

For a 600 sq ft project, expect 2-4 weeks construction time once permits are approved. The substructure uses pressure-treated lumber even with composite decking, and proper ventilation underneath is critical in Vancouver's humid climate to prevent moisture buildup that can cause structural issues.
