How much does it cost to fix popped deck screws and nail pops in NB?

Fixing popped deck screws and nail pops typically costs $200-800 for a standard deck in New Brunswick, depending on the extent of the problem and whether you hire a professional or tackle it yourself.

Popped fasteners are extremely common in NB decks due to our harsh freeze-thaw cycles. When temperatures swing from -35°C in winter to +35°C in summer, wood expands and contracts repeatedly, gradually working screws and nails loose. This is especially problematic with pressure-treated lumber, which can continue shrinking for 6-12 months after installation.

DIY Repair Costs run $50-200 for materials. You'll need exterior-grade deck screws (2½" minimum length), a drill/driver, and possibly a nail set for countersinking. Quality stainless steel or coated deck screws cost $15-25 per pound, and you'll typically need 1-3 pounds depending on how many fasteners need replacement. If boards have split around old fasteners, add $3-8 per linear foot for replacement boards.

Professional repair costs range from $200-800 total. Most deck contractors charge $75-150 per hour, and a typical popped fastener repair takes 2-6 hours depending on deck size and access. Some contractors offer this as part of annual deck maintenance packages for $300-500, which often includes cleaning, fastener tightening, and minor board replacement.

The repair process involves removing old nails/screws, pre-drilling new holes slightly offset from the original locations, and installing proper deck screws. Never just hammer popped nails back down — they'll pop again within months. In NB's climate, screws hold much better than nails because they resist the constant expansion and contraction cycles.

Timing matters significantly in New Brunswick. Schedule repairs between May and September when wood moisture content is stable. Attempting repairs during winter freeze-thaw periods often leads to immediate re-popping as the wood continues moving.

Prevention saves money long-term. When building or replacing deck boards, use screws instead of nails, pre-drill holes in hardwoods like cedar, and allow pressure-treated lumber to dry for 3-6 months before final fastening. Many NB deck builders now use hidden fastening systems for composite decking specifically to eliminate this problem.

When to hire a professional: If you're dealing with structural fasteners (joist hangers, beam connections, ledger board), always hire a qualified deck contractor. Surface board repairs are typically DIY-friendly, but structural fastener failure can be a safety hazard requiring proper engineering assessment.
