How much for a typical Vancouver PT deck redo $?

A typical pressure-treated deck replacement in Metro Vancouver runs $9,000-$16,500 for a standard 300 square foot deck, including demolition of the old deck, new footings, framing, PT decking, basic railing, and labour.

The wide price range depends on several key factors. Ground-level decks with simple rectangular layouts fall toward the lower end, while elevated decks requiring permits, engineered connections, and code-compliant guardrails push costs higher. If your existing deck is over 600mm (2 feet) above grade, you'll need a building permit, which adds $200-$800 depending on your municipality.

Demolition and disposal of your old deck typically adds $1,000-$3,000 to the project cost. Multi-level decks, decks with built-in planters, or those requiring crane access for removal cost more. Many contractors include basic demo in their quotes, but confirm this upfront.

Metro Vancouver's marine climate makes proper construction details critical for PT deck longevity. Your contractor should use hot-dipped galvanized or stainless steel fasteners exclusively — standard zinc-plated screws corrode rapidly in our 60-80% humidity levels and are incompatible with ACQ pressure-treated lumber. Proper ground clearance (minimum 12 inches) and ventilation underneath prevents the trapped moisture that causes premature rot in our 1,200mm+ annual rainfall.

Additional costs to budget for include stairs ($100-$250 per step), upgraded railing systems (cable railing adds $100-$250 per linear foot), and initial staining or sealing ($2-$4 per square foot). While PT lumber is structurally sound, it requires staining within the first year for weather protection and appearance — especially important in Vancouver's persistent dampness.

Elevated decks cost 30-50% more than ground-level replacements due to engineering requirements, proper ledger board connections with flashing, and seismic bracing required by BC Building Code. If your deck serves as an exit from an upper floor or is over habitable space, waterproof membrane installation may be required, adding $15-$30 per square foot.

Hire a professional for any deck over 600mm above grade — this requires permits, structural engineering knowledge, and proper guardrail installation. PT deck replacement is one of the most cost-effective ways to extend your outdoor living space, but proper construction details make the difference between a deck that lasts 15 years versus one that needs major repairs in 7-10 years.
