We're considering reclaimed wood for character, but are there stability issues or hidden metal problems we should worry about?

Reclaimed wood is a fantastic choice for character and warmth, and your instincts to ask about potential issues are exactly right — there are a few real concerns worth understanding before committing.

Stability is the biggest consideration with reclaimed wood. Unlike kiln-dried new lumber, reclaimed wood has often been exposed to decades of humidity swings, structural loads, and environmental changes. This means the wood may have already done most of its expanding and contracting, which can actually be an advantage — but it also means you need to carefully assess moisture content before installation. Any reclaimed wood should be tested with a moisture meter and acclimated to your home's conditions for at least 2-3 weeks, sometimes longer, before installation begins.

Hidden metal is a very real hazard that catches many installers off guard. Old barn boards, factory flooring, and industrial reclaimed wood frequently contain embedded nails, staples, screws, or even bolt fragments that have been painted or stained over. These can damage saw blades, planer heads, and sanding equipment — and they create serious safety risks. A professional installer should use a metal detector or rare-earth magnet to sweep every board before milling or cutting. This step is non-negotiable with reclaimed material.

Grading and milling consistency is another hidden challenge. Reclaimed boards are often irregular in thickness, cupped, or twisted from years of use. They typically need to be re-milled (face-planed and re-dimensioned) to achieve a consistent thickness for installation. This adds cost and waste to your material budget, so factor in 15-20% extra material beyond your square footage to account for defects and cuts.

In the Ottawa market, sourcing quality reclaimed wood from reputable local suppliers — rather than unknown online sources — makes a significant difference. Well-sourced reclaimed oak, pine, or elm from Ontario barns and heritage buildings tends to be more stable and better documented than material of unknown origin. Installed costs for reclaimed hardwood typically run $15 - $25+ per square foot, reflecting the extra labour involved in sorting, testing, and fitting irregular material.

From a practical standpoint, reclaimed wood pairs best with nail-down installation over a plywood subfloor — floating or glue-down methods are harder to execute reliably with irregular boards. Your subfloor also needs to be exceptionally flat (within 3/16" over 10 feet) because reclaimed boards are less forgiving than uniform new flooring.

If you're seriously considering reclaimed wood, we'd recommend having a professional assess your subfloor and review your material source before purchasing.
