Our kitchen dishwasher leaked last year and now a few hardwood boards are slightly darker — is that surface damage or rot underneath?

Darker hardwood boards from dishwasher leaks typically indicate water penetration into the wood, which can range from surface staining to deeper moisture damage that may lead to rot if not addressed.

The darkening you're seeing is likely water staining where moisture has penetrated the wood fibers and finish. Since this happened a year ago, the immediate concern is whether the moisture was fully dried out or if it's created conditions for mold growth or wood rot underneath the surface. Even if the boards feel solid now, trapped moisture can cause ongoing damage to both the hardwood and the subfloor beneath.

Professional assessment is crucial because what appears as surface discoloration often extends deeper than visible. A licensed flooring contractor can use moisture meters to check if elevated moisture levels remain in the affected boards and subfloor. They'll also inspect for signs of mold, soft spots, or early rot that aren't immediately obvious. In Ottawa's climate, trapped moisture in flooring systems can create ongoing problems even months after the initial leak.

The repair approach depends on the extent of damage. Surface staining might be addressed through sanding and refinishing those specific boards. However, if moisture penetrated to the subfloor or if any boards show signs of rot, those sections will need complete replacement. The subfloor may also require treatment or replacement if it was compromised.

Don't wait to have this evaluated - moisture damage in hardwood flooring typically worsens over time, and what starts as cosmetic staining can develop into structural issues requiring more extensive repairs. For a professional moisture assessment and repair estimate, request a consultation from Ottawa Floor Install to determine the full scope of the damage and prevent future problems.
