Board repair and replacement
When only some planks are ruined, we pull the damaged boards and install matched replacements (species, width, and grade as close as the floor allows), then blend the repair into a full sand and finish. Individual hardwood floor board replacement and plank replacement are part of refinishing prep when the rest of the floor is still sound.
Brownstone and older Brooklyn homes often need this mix of repair and refinishing after plumbing leaks.
Subfloor checks before we sand
Before we sand, we check for wet or soft subfloor, lingering moisture, and fasteners that failed when boards cupped. If the subfloor needs repair or drying time, we say so on the free on-site measure — refinishing over active moisture does not last. See our subfloor repair page for how we prepare the base.
Refinish vs replace
If most of the wear layer is intact and damage is local, sanding, board repairs, and a new finish usually restore the floor. If boards are rotten through, the wear layer is gone, or moisture keeps coming back, replacement of those areas (or a larger install) is the honest path.
We walk you through refinish vs replace on site. Use the Instant Preliminary Estimate for planning, then schedule a free measure.

What affects the cost
Water damage repair is scoped by how far the moisture spread: how many boards are cupped, stained or soft, and whether they can be flattened and refinished or need to be replaced. Subfloor condition under the damaged area, matching the existing species and finish, and whether surrounding rooms need to be sanded and refinished to blend the repair all shape the quote. The final quote is confirmed after we inspect the floor; for a planning number first, get an instant preliminary estimate.
Frequently asked questions
Can you repair water-damaged hardwood and replace boards before refinishing?
Yes. We repair water-damaged hardwood, replace individual boards or planks when needed, check the subfloor for moisture or soft spots, then sand and finish the floor as one blended surface when refinishing is still the right path.
When is replacement the better choice?
Choose replacement when boards are rotten, cupped beyond repair, too thin to sand, or moisture problems keep returning. We recommend a path after inspection — not a slogan.
Can I stay in my home while floors are refinished?
Many homeowners stay during a dust-controlled sanding job when work is room by room and the finish is low-odor water-based. You still need to keep off wet finish and give the crew clear rooms.
Do you give free estimates?
Yes. Use the Instant Preliminary Estimate for a planning number, then your final quote is confirmed after a free on-site measure.
