The floor gap after removing a wall between a kitchen and a living room is really a strip of bare subfloor, plus two floors that stop at that line without meeting properly. Three routes close it: lace new boards into the floor you are keeping, cover the old wall line with a transition, or refloor both rooms as one continuous floor. The choice is settled during project planning, once the subfloor, the floor heights and the board direction are known. The cost gap is wide: patching a 6 sq ft strip with our solid hardwood comes to $141.66 in the worked example below, against $3,129.33 to $4,522.53 to refloor a 420 sq ft room.
What is actually under that strip
A wall sits on a sill plate fixed to the subfloor, and the finished flooring stops on both sides of it. Take the wall and plate out and you are looking at a band of subfloor one wall thickness wide, often with nail holes where the plate was fixed.
Three details decide which option is realistic.
- The subfloor. Plywood that flexes, squeaks or sags has to be repaired first.
- The height of each floor. Floors built at different times may not finish level.
- The floor on each side. Solid wood is nailed down and can be stitched into; a click floor cannot.
The third decides which of the three options is open to you. What carries the old wall line is settled in the renovation plan first.
Option 1: lace new boards into the existing floor
This option keeps the floor you own. It works when the wood on both sides of the gap is the same floor, or close enough once blended.
What lacing means
Lacing is the trade term for integrating a new wood floor with an existing wood floor, and the National Wood Flooring Association's guidelines use that description.
The boards have to match the floor, not just the colour
The same guidelines are strict: the new boards must be the same species, grade, width, edge profile, bevel, average length, thickness and cut. New material should also sit within 2% MC of the flooring around it, so boards settle in the room before they are cut.
If you are keeping red oak, matching is realistic, because red oak strip is still made in this width. Two options in 4 1/4 inch: Appalachian Natural Red Oak in Excel Grade at $103.76 per 18.9 sq ft box, or $5.49/sq ft, and Lauzon Essential Red Oak Limes at $91.63 per 17.0 sq ft box, or $5.39/sq ft.
The removal pattern is part of the job
Boards come out before boards go in. The guidance is to choose them so the pattern avoids H shapes and blatant stair-steps in the floor that stays.
Board direction
Direction limits how invisible a lace-in can be. Appalachian's solid hardwood guide says flooring should be laid perpendicular to the floor joists for stability, and Lauzon's says perpendicular or at 45 degrees. Where both rooms run the same way, the new boards continue the lines; where they meet at right angles, the strip is where the direction changes. Our guide to continuous flooring direction between rooms covers the design side.
Option 2: a transition on the old wall line
A transition is the right answer when the two floors will not become one. A reducer is the standard profile: the NWFA describes reducers as the piece that provides a smooth transition between floors of uneven heights.
A transition covers the line without touching either floor, which makes it the choice when a side is tile, glued vinyl or wood you are not touching. The catch is that it reads as a deliberate line, which can undo some of the openness.
Matching reducers and T-mouldings are sold in our trims and transitions collection, and the profile is chosen from the two floor heights when the job is planned. On a floating floor, Lauzon's guide also requires a T-shaped molding between adjacent rooms more than 16 ft wide joined by a door 3 ft wide or less.
Option 3: refloor both rooms as one continuous floor
Reflooring replaces both floors at once, which is the only one of the three routes that ends with one continuous floor. Matching an old floor also gets harder as it ages, and a wide patch shows more than a narrow one.
Here is what the four floors cost today.
| Floor | Format | Box price | Coverage per box | Price per sq ft |
|---|---|---|---|---|
| Appalachian Natural Red Oak, Excel Grade | Solid, 4 1/4 inch, 19mm (3/4") | $103.76 | 18.9 sq ft | $5.49 |
| Lauzon Essential Red Oak Limes | Solid, 4 1/4 inch, 19mm (3/4") | $91.63 | 17.0 sq ft | $5.39 |
| European Oak Cloud | Engineered, 7 1/2 inch, 3mm top layer | $85.25 | 19.42 sq ft | $4.39 |
| Riche Stone Grey Oak SPC | Vinyl, 10mm, 20mil wear layer, click-lock | $38.89 | 11.82 sq ft | $3.29 |
Prices checked October 23, 2026. Box prices and coverage come from our current catalogue, and price per sq ft is the box price divided by the coverage.
The engineered oak is the surprise: 7 1/2 inch wide with a 3mm top layer, and cheaper per square foot than either solid oak. The SPC costs less, but it is a click floor.
Patch or refloor: what the two routes cost
Every figure below uses the arithmetic our quotes use, without delivery: a full quote adds the flat GTA delivery charge. Add 5% waste, divide by the coverage in one box and round up for material, then apply our house rates, which are also the basement rates: $2.00 per sq ft to install hardwood, $1.50 per sq ft to install vinyl, and $1.50 per sq ft to remove nailed hardwood. HST is 13%.
Patching a strip
Take the Appalachian solid oak. A wall 12 ft long leaves a strip about 6 in wide, so 6 sq ft; a long run across an open main floor can leave 20 sq ft.
| Strip area | Boxes | Material | Labour | Removal | Total with HST |
|---|---|---|---|---|---|
| 6 sq ft | 1 | $103.76 | $12.60 | $9.00 | $141.66 |
| 20 sq ft | 2 | $207.52 | $42.00 | $30.00 | $315.86 |
The one-box minimum is what you pay for: a 6 sq ft strip still needs one 18.9 sq ft box. Per square foot the small patch looks expensive at $23.61 and the 20 sq ft version is $15.79, but each total is a fraction of either room.
Reflooring the combined room
Now the other side: a 420 sq ft combined kitchen and living room, say 21 ft by 20 ft, with the old nailed hardwood taken out first. The vinyl uses the rate for jobs of 301 sq ft and up.
| Floor | Boxes | Material | Labour | Removal | Total with HST |
|---|---|---|---|---|---|
| Appalachian solid oak | 24 | $2,490.24 | $882.00 | $630.00 | $4,522.53 |
| Lauzon solid oak | 26 | $2,382.38 | $882.00 | $630.00 | $4,400.65 |
| European Oak engineered | 23 | $1,960.75 | $882.00 | $630.00 | $3,924.21 |
| Riche SPC vinyl | 38 | $1,477.82 | $661.50 | $630.00 | $3,129.33 |
Before delivery, that is $7.45 to $10.77 per sq ft with HST, against $141.66 to $315.86 for the strip. One buys a finished floor across 420 sq ft, the other a repair on 6 to 20 sq ft.
Two limits. In a condo, vinyl installation is $2.00 per sq ft instead of $1.50, and hardwood is priced after viewing. Removal of glued floors and tile is also priced after viewing. Our installation cost guide runs the same arithmetic across more materials.
Which option fits your room
- Lace in when both sides are the same species and width, the boards run the same way, and matching boards are still available. A strip under about 10 sq ft is the sweet spot, at one or two boxes.
- Transition when the heights differ and both floors stay, when one side is tile or glued vinyl, or when the floor is a floating click product.
- Refloor when the rooms are already different floors, when the patch would be wider than a few boards, or when the old finish is too worn for new boards to blend.
- Refloor the whole area at once if other rooms are on the list: one order keeps the material from one batch and the work to one visit. Our notes on sequencing a multi-room flooring replacement cover it.
If the rooms stay open, the floor for the wider space matters as much as the strip. Our guide to flooring for open-concept Toronto homes takes that question on.
What to check before the work is booked
Four checks catch the problems that show up after a wall comes out; the moisture one needs a meter rather than a tape measure.
- Flatness. Appalachian's guide asks for a subfloor within 3/16 inch over 10 ft and 1/8 inch over 6 ft. A strip over a dip will rock.
- Soundness. The same guide says no creaking, loose edges or sags should exist, and that they should be repaired before installation.
- Moisture. New boards should be within 2% MC of the old floor, so both need time to settle in the room.
- Height at the joint. Measure the difference between the finished surfaces. That number decides whether a reducer fits under the casing, or whether the floors must be brought level first.
Photos, a tape measure across the widest part and the height difference are enough to price the work. If the subfloor looks soft, our guide to whether a subfloor needs replacing explains what to look at next.
Frequently asked questions about a floor gap after a wall removal
How do you close the gap where a wall was removed?
Lace matching boards into the floor you are keeping, fit a transition over the old wall line, or take up both floors and lay one across the combined room. It depends on whether the floors match, whether they finish at the same height, and whether the floor is nailed wood or floating.
Can hardwood be patched where the wall stood?
Yes, when the boards match in species, width and thickness and the strip is narrow enough for the removal pattern to be hidden. Our 6 sq ft example in Appalachian solid oak comes to $141.66 including HST, and $103.76 of that is one box of flooring.
Is patching cheaper than reflooring both rooms?
In total, yes, by a wide margin: $141.66 to $315.86 against $3,129.33 to $4,522.53 for 420 sq ft. Per square foot the patch is the expensive way to buy floor, at $23.61, because you pay for a full box to cover a few square feet.
Can you lace new boards into a click vinyl floor?
Lacing is a wood-floor method, so a floating click floor is handled differently. The options are a transition over the old wall line or a refloor, where vinyl installation runs $1.50 per sq ft in a house and $2.00 per sq ft in a condo for jobs of 301 sq ft and up.
What does it cost to fix the floor after removing a wall in Toronto?
For the strip itself, $141.66 for 6 sq ft or $315.86 for 20 sq ft in solid oak, with our house rates and HST. A full refloor starts at $3,129.33 with SPC vinyl. Every job is confirmed at quote, because the subfloor and the floor heights can change the plan.
