A cracked board by the back door, a dark pet stain in the hallway or a gouge where the fridge was dragged out does not have to mean a new floor. In a nailed solid hardwood floor, one damaged board can be cut out and replaced on its own, and a larger area can be woven in so the new boards follow the old pattern. Below we explain how to replace damaged hardwood boards both ways, how to check a match against boards from our solid hardwood flooring collection, and what a section costs at our current rates.
The short answer: yes, boards can be swapped one at a time
- One or two damaged boards: cut the board out in strips, trim the bottom lip off the replacement's groove, drop it in from above and fasten it through the face.
- Damage across several rows: remove boards back to staggered end points and weave new boards in, nailed through the tongue like the original floor.
- The match decides the result: width and thickness first, then species, grade, colour and sheen.
- Cost anchors: our rate sheet lists removal of nailed hardwood at $1.50 per sq ft and hardwood installation at $2.00 per sq ft for a house; a repair of just a few boards is quoted after viewing.
Pick the repair by the kind of damage
A single cracked, split or deeply dented board
This is the classic one-board swap. The damage sits in one board and its neighbours are sound and flat. Cut out only that board, or only the damaged length of a long one, ending where the new joint will not line up with joints in the next rows.
A dark stain running across several boards
When a stain has gone into the wood rather than the finish, those boards are replaced. Stop the moisture source and let the area dry first. If the boards have cupped or crowned, read our cupping vs crowning guide before cutting.
Pet damage: urine stains and claw gouges
Pet urine that has darkened the wood is handled like any deep stain. Claw marks in the finish need a touch-up or refinish instead; see our guide to removing scratches from hardwood. Replace a board for a gouge only when it is too deep to sand out.
When a patch is not worth it
A patch makes sense when the rest of the floor is staying. If damage is scattered across most of a room, no board of the right width exists, or the whole floor needs sanding anyway, compare the whole-floor options in our refinish vs replace cost guide.
Matching new boards to the floor you are keeping
These four nail-down solid boards from our current stock suit floors of the same size and species.
| Board | Species and grade | Width x thickness (inches) | Box price and coverage | Price per sq ft |
|---|---|---|---|---|
| Appalachian Natural Red Oak, semi gloss | Red oak, Excel Grade | 4 1/4 x 3/4 | $101.87 for 18.9 sq ft | $5.39 |
| Lauzon Essential Hard Maple Sapphir | Hard maple, Essential | 4 1/4 x 3/4 | $99.80 for 17.0 sq ft | $5.87 |
| Appalachian Paisley White Oak, semi gloss | White oak, Prestige Grade | 4 1/4 x 3/4 | $126.44 for 18.9 sq ft | $6.69 |
| MKB Red Oak Epicea | Red oak, Character grade | 4 1/4 x 3/4 | $118.83 for 17.0 sq ft | $6.99 |
Prices checked October 6, 2026. Price per square foot is the box price divided by the box coverage, rounded to the cent.
Width and thickness come first
Pull a floor register or check a threshold, then measure the face width and full thickness. All four boards above are 4 1/4 inches wide and 3/4 inch thick according to their product titles and spec lists, and your floor may differ. If it does, they will not weave in cleanly: a different width breaks the line of every row it touches. Look for a reclaimed board of the right size instead.
Species and grade
Red oak, white oak and maple each have their own grain, so the species has to match before anything else. Grade controls how many knots and streaks show. On the product pages, Appalachian's Excel Grade "features more natural character marks, colour variation, and grain movement", while its Prestige Grade means "consistent colour, minimal character marks". Lauzon's maple has a "tight, uniform grain with minimal knot variation in the Essential grade", and MKB's Character grade brings "open knots, mineral streaks, and varied grain". A clean board in a knotty floor stands out about as much as a colour mismatch.
Colour and sheen
Boards that have spent years in sunlight rarely look like a board fresh from the box. Sheen matters too: both Appalachian boards list a semi gloss finish. Some colours are a stain, such as the cool blue-grey on the Lauzon Sapphir maple, which only patches into a floor with the same stain. Compare against a loose board or a daylight photo, and see our overview of in-stock stain colours.
Replacing a single board, step by step
Tools: a depth-adjustable circular saw, an oscillating multi-tool or chisel, a pry bar, hammer and nail set, wood glue, colour-matched filler and eye protection.
- Mark and protect. Tape off the board and cover its neighbours.
- Set the saw depth. Set the blade to cut just through the board's measured thickness, not into the subfloor.
- Cut the board into strips. Make two parallel cuts along its length, inside the edges, and finish the ends with the multi-tool or chisel.
- Lift it out. Pry out the middle strip, then the groove side. Work the nailed tongue side loose gently, pull or set leftover nails, and vacuum.
- Check underneath. If the subfloor is soft, stained or wet, stop. That has to be fixed first, and subfloor repair is quoted after we see the floor.
- Prepare the new board. Let it acclimate in the room: Lauzon's product page recommends a minimum of 3 to 5 days in the installation area, and MKB's asks for a minimum of 72 hours. Cut it to length, then remove the bottom lip of the groove so it can drop in from above.
- Fit and fasten. Hook the tongue into the neighbouring groove, lower the board and tap it flush with a scrap block. Glue the trimmed edge, face-nail it, then set the nails and fill the holes.
- Blend the finish. A factory-finished board may be ready as it is; on a site-finished floor, finishing to match is quoted after seeing the floor.
Weaving in new boards across a larger area
For damage spanning several rows, remove whole boards or board lengths so each row ends at a different point, the way the floor was first laid. That stepped outline lets the new boards blend in.
- Mark the damaged boards, then extend the marks row by row so the ends of the opening are staggered.
- Remove them with the strip method above, working from the middle outward.
- Lay new boards from the groove side, fitting each groove over the existing tongue and blind-nailing through the new tongue into the subfloor. For fastener spacing on 3/4 inch solid boards, follow our nail schedule guide.
- Mix board lengths so no two neighbouring rows end at the same spot.
- The last board has no open tongue to nail through, so it goes in like a single replacement: groove lip trimmed, glued and face-nailed.
If boards around the opening squeak or flex, fasten them down now; our article on fixing squeaky hardwood explains the usual causes.
What a section replacement costs with our rates
Our removal and installation rates are per square foot of floor and are house rates; the basement column is the same. The condo column has no published figure for either, so condo hardwood work is priced after viewing. The arithmetic follows the way we build every quote:
- Waste-adjusted area = area x 1.05 (a 5% allowance for cuts).
- Boxes = waste-adjusted area divided by coverage per box, rounded up to whole boxes.
- Material = boxes x box price.
- Installation = waste-adjusted area x $2.00.
- Removal and disposal = original area x $1.50, with no waste added.
- HST = 13% of the subtotal, added to give the total.
Take a 60 sq ft section, for example a 6 x 10 ft area inside a back door. The waste-adjusted area is 63 sq ft, so installation is $126.00 and removal is $90.00, or $216.00 together.
| Board | Boxes | Material | Installation and removal | Subtotal | HST (13%) | Total |
|---|---|---|---|---|---|---|
| Lauzon Essential Hard Maple Sapphir | 4 | $399.20 | $216.00 | $615.20 | $79.98 | $695.18 |
| Appalachian Natural Red Oak | 4 | $407.48 | $216.00 | $623.48 | $81.05 | $704.53 |
| MKB Red Oak Epicea Character | 4 | $475.32 | $216.00 | $691.32 | $89.87 | $781.19 |
| Appalachian Paisley White Oak | 4 | $505.76 | $216.00 | $721.76 | $93.83 | $815.59 |
Not included: delivery and any trim, which have their own published rates and are confirmed in your quote, plus sanding or finishing to blend the patch and subfloor repair, both quoted after seeing the floor.
Why the leftover boards matter
Boxes are sold whole, so every repair leaves spares. Four boxes of either Appalachian board cover 75.6 sq ft and four of the Lauzon or MKB board cover 68 sq ft, leaving 12.6 sq ft or 5 sq ft beyond the 63 sq ft needed. Keep them flat in a dry room for the next repair. Even a two-board fix means buying a full box: $101.87 for the Appalachian red oak.
Questions about replacing hardwood boards
Can I replace just one hardwood board without lifting the rest?
Yes, in a nailed tongue-and-groove floor. The old board is sawn out where it lies and the new one goes in from the top once its lower groove lip is cut off. The boards beside it stay put.
How much does it cost to replace floor boards?
For a section, add the boards and 13% HST to our house labour: $1.50 per sq ft to take out the old floor plus $2.00 per sq ft to lay the new one. The 60 sq ft example above lands between $695.18 and $815.59 with HST. Small jobs are priced after we see them.
What is the difference between refinishing, patching and replacing a floor?
Refinishing sands the surface and applies a new finish, so every board stays. Patching removes only the damaged boards. Full replacement takes the entire floor out and lays a new one.
Will the new boards match my old floor exactly?
Expect some difference unless the boards come from the original batch. Matching width, thickness, species and grade gets you close; colour and sheen take the most care.
Do you replace hardwood boards in condos?
Yes, but there is no published condo figure for hardwood removal or installation on our rate sheet, so condo repairs are priced after viewing. Check your building's own rules before you book the work.
