How much do contractors charge for deck repair in Ottawa?

Deck repair costs in Ottawa typically range from $300-800 for minor repairs, $800-2,500 for moderate repairs, and $2,500-6,000+ for major structural work, depending on the scope and materials needed.

Minor repairs like replacing a few deck boards, tightening loose railings, or basic staining usually cost $300-800. This includes fixing squeaky boards, replacing damaged spindles, or touch-up work on small sections. Most contractors charge $75-120 per hour for this type of work, and simple repairs often take 3-8 hours to complete.

Moderate repairs in the $800-2,500 range cover more extensive board replacement, railing section rebuilds, joist repairs, or complete refinishing. If you're replacing 20-30% of your deck boards, expect to pay $15-25 per square foot depending on material choice. Pressure-treated lumber is most affordable, while cedar or composite replacements cost significantly more. Ottawa's harsh freeze-thaw cycles are particularly tough on deck fasteners and board ends, so these repairs are common on decks over 10 years old.

Major repairs exceeding $2,500 involve structural issues like foundation problems, extensive joist replacement, or rebuilding large sections. If your deck has significant rot, structural damage, or needs new footings due to frost heave (common in Ottawa's clay soil), you're looking at $25-45 per square foot. At this point, many homeowners consider full replacement instead.

Ottawa-specific factors that affect pricing include our extreme temperature swings, which cause more expansion and contraction damage than milder climates. Many older Ottawa homes have decks built before current building codes, so repairs often require upgrades to meet today's standards. If your repair involves structural changes or exceeds 10 square meters, you'll need a City of Ottawa building permit ($200-400), which adds to the total cost.

What's typically included in repair quotes: labor, basic materials, debris removal, and cleanup. What's usually extra: permits, structural engineering (if required), premium materials like composite decking, and any electrical work for lighting. Many contractors offer package deals if you're doing multiple repairs simultaneously.

Professional guidance: While homeowners can handle basic board replacement and staining, structural repairs require proper assessment of load-bearing elements and code compliance. Ottawa's building code requires specific joist spacing, railing heights, and foundation depths that affect repair approaches.
