Is it cheaper to resurface my old pressure-treated deck with new boards or tear it down and start over in Port Coquitlam?

Resurfacing is typically 40-60% cheaper than a complete rebuild if your existing deck structure is sound. In Port Coquitlam's wet climate, the key question is whether your joists, beams, and posts are still structurally solid after years of Metro Vancouver's persistent moisture exposure.

Resurfacing costs for a typical 300 sq ft deck run $4,500-$9,000 depending on your new decking material choice. This includes removing old boards, inspecting and replacing any damaged joists, installing new decking (cedar, composite, or upgraded pressure-treated), and refinishing. You're essentially keeping the foundation and frame while getting a completely new deck surface and extended lifespan.

Complete rebuild costs for the same deck run $9,000-$25,500 depending on materials and complexity. However, you get new footings, updated framing to current BC Building Code standards, proper drainage improvements, and the opportunity to modify the deck layout, add features like built-in benches or planters, or upgrade to composite decking that requires virtually no maintenance in our rainy climate.

The structural inspection is critical before deciding. Pressure-treated lumber from 10-15 years ago used different preservative treatments and may show rot or insect damage despite the chemical treatment. Check for soft spots in joists, loose post connections, and any sagging or bouncing when you walk across the deck. In Port Coquitlam's climate, pay special attention to areas where water pools or where the deck meets the house — these are the first places moisture damage appears.

Resurfacing makes financial sense when your existing joists are solid, the deck height and layout work for your needs, and the foundation is stable. You can upgrade to cedar or composite decking for better longevity and appearance while keeping costs reasonable. Many Port Coquitlam homeowners choose this route to get 15-20 more years from their deck investment.

Rebuild when you find structural issues during inspection, want to change the deck size or configuration, need to bring an older deck up to current guardrail codes (42-inch minimum height), or want to add features like integrated lighting or hot tub support. A rebuild also lets you improve drainage and ventilation underneath — critical for deck longevity in our wet climate.

Port Coquitlam permit considerations: If your existing deck is over 600mm (2 feet) above grade and you're doing a complete rebuild, you'll need a building permit. Resurfacing typically doesn't require a permit unless you're modifying the structure. Check with Port Coquitlam's building department to confirm your specific situation.

Have a qualified deck contractor inspect your existing structure before deciding. The $200-$400 inspection cost can save you from choosing resurfacing on a deck that needs rebuilding, or rebuilding a deck that could serve you well for years with just new boards.
