Hardwood Floor Repair

Hardwood repair work depends on the damage type. Water damage shows up as cupping (edges higher than centers) or crowning (centers higher than edges). If the wood is still wet, we dry it out first with dehumidifiers and fans—sometimes cupped boards flatten back out as they dry. If they don't, we sand the floor flat once moisture content drops below 12%. Severe cupping means the boards are too distorted to sand flat, and we replace them.

Replacing individual boards means weaving in new planks. We cut out the damaged board, chisel out the tongue, and slide in a new piece with the bottom of the groove removed so it drops into place. Matching the species is easy if you have common red oak or maple. Matching the finish is harder—new wood looks different even with the same stain because wood color changes over time. We sand and refinish a blended area (the whole room, or feathered edges) so the repair disappears. Spot repairs where we only finish the new board always show unless your floor is already heavily distressed.

“Gaps under 1/8 inch are normal seasonal movement—gaps over 1/4 inch mean the floor wasn't acclimated properly or your indoor humidity is too low.”

Gaps between boards are normal in the area winters when humidity drops and wood shrinks. Gaps under 1/8 inch are cosmetic, not structural. Gaps over 1/4 inch mean the floor wasn't acclimated properly before install, or you've got extreme humidity swings (below 25% in winter). We fill wide gaps with wood filler or rope filler stained to match, but the real fix is a whole-house humidifier to keep winter humidity above 35%.

Squeaks come from subfloor movement or loose boards rubbing. From below, we drive screws up through the subfloor into the hardwood to pull it tight. From above, we face-nail through the hardwood into the joist, countersink the nail, fill with wood putty. If you're refinishing anyway, we fix squeaks during the prep work. If not, the repair shows unless we match the putty perfectly.

Repair timeline is 1-2 days for plank replacement and blending, longer if we're refinishing the whole room to hide the repair.
