How much does it cost to replace 10 warped deck boards in Fredericton NB?

Replacing 10 warped deck boards in Fredericton typically costs $300–$800, depending on the material and how much labour is involved.

For a straightforward surface board swap — no structural damage underneath — this is one of the more manageable deck repairs. The cost breaks down into materials and labour, and the range is wide because it depends heavily on what your existing boards are made of and whether any of the joists beneath have been affected by moisture.

Material costs are your first variable. If you're matching existing pressure-treated lumber (the most common decking in Fredericton), replacement boards run roughly $3–$6 per linear foot. For a standard 12-foot deck board, that's $36–$72 per board, so 10 boards puts you at $360–$720 in materials alone. Cedar boards cost a bit more — $5–$10 per linear foot. If you're trying to match composite decking, individual boards can run $8–$20+ per linear foot, and matching an existing colour/brand can be tricky if the product line has changed.

Labour for 10 boards typically runs $150–$400 in the Fredericton market. A skilled carpenter can swap out surface boards fairly quickly — figure 3–5 hours of work depending on fastener type (hidden fasteners take longer than face screws), board length, and accessibility. If your deck uses hidden clip fasteners, expect labour costs toward the higher end.

One important NB-specific warning: warped boards in Fredericton are often a symptom of our freeze-thaw cycle working moisture into the wood. Before replacing boards, have the contractor check the joists underneath. If the joists show rot or soft spots, you're looking at a more significant repair — $1,500–$3,500 for joist work — and it's worth knowing that before you invest in new surface boards.

A few practical tips before you start:

• If your deck is pressure-treated and more than a few years old, bring a new board alongside an old one to the lumber yard to match the treatment type and size
• New PT boards need to dry 3–6 months before staining — plan for that if you're doing a full refinish afterward
• Use stainless steel or coated exterior screws only — standard screws will rust and stain your new boards within one season in NB's humidity
• This is a good time to power wash and re-stain the whole deck surface ($600–$1,200 for a typical Fredericton deck) so everything looks uniform

This is a project many handy homeowners can tackle themselves if the damage is purely surface-level — pry off the old boards, check the joists visually, and screw down new ones. Where you want a professional is if you find soft joists, if the ledger board area looks dark or spongy, or if more than a few boards are affected (which can signal a drainage or ventilation issue worth diagnosing properly).
