An old semi or worker cottage in the east end rarely takes a new floor the way a recent build does. Rooms are narrow, the framing has had about a century to settle, and the finished floor may sit on a board subfloor instead of a sheet of plywood. For most of these houses the answer comes down to three builds: engineered oak or solid maple nailed down where the subfloor is flat and firm, and a waterproof click-lock plank for rooms below grade. Choosing East York flooring for a house of this age, or for a Leslieville semi, starts with those checks rather than with colour. Every price below comes from our current catalogue, and our engineered hardwood collection holds the nailed side of that list.
Quick answer: what suits a pre-war east-end semi or cottage?
Four floors from our catalogue, in three builds, cover the main choices. The table shows what each one costs per square foot today and what sits inside the box.
| Floor | Build and thickness | Box price and coverage | Material per sq ft |
|---|---|---|---|
| Slate European oak engineered | 2mm oak top layer, 6 1/2" wide plank, 19mm (3/4") thick, nail-down | $95.71 per 20.24 sq ft box | $4.73 |
| Cocoa European oak engineered | same build as Slate, another colour | $95.71 per 20.24 sq ft box | $4.73 |
| Lauzon Essential hard maple solid | solid hard maple, 4 1/4" wide board, 19mm (3/4") thick, nail-down | $99.80 per 17 sq ft box | $5.87 |
| Riche Blonde Sand Oak SPC | 6mm thick, 7.09" wide plank, 12mil wear layer, IXPE pad, click-lock | $62.93 per 23.64 sq ft box | $2.66 |
Prices checked October 6, 2026. Box prices and coverage come from our current catalogue.
The first two rows are the same floor in two colours, and the last row is the one to reach for below grade. Material across the four runs from $2.66 to $5.87 per sq ft, so let the room and the subfloor narrow the choice before the price does.
What an older east-end house asks of its floor
The City of Toronto staff report on the Kingswood Road South Heritage Conservation District, in Balmy Beach, gives a sense of how old this housing is: it dates the earliest homes on that street to 1909 and records that the bulk of dwellings were built between 1910 and 1920. A house of that generation has had a long time for its joists to settle, and the movement can show up as small dips and crowns across a room rather than as one obvious slope.
Two checks decide whether new boards can go straight down, and both are quick to make.
Level and flat are not the same thing
A floor can run downhill toward an outside wall and still be fine to lay over. NWFA, the wood flooring trade association, says it plainly in its installation guidelines: "The floor does not need to be level in most situations, but should be flat." The same guidelines set the tolerance for installations using mechanical fasteners of 1 1/2 inches and longer at 3/16" in 6', or 1/4" in 10', unless the flooring manufacturer specifies otherwise. A long straight edge laid across the room in several directions shows where the floor dips or crowns. Levelling and subfloor repair are priced after we see the floor, because the size of that work depends on how far the framing has moved.
What sits under the finished floor
In a basement with an open ceiling you can usually look up and see what the floor is built on. Where it is solid boards rather than sheet panels, the NWFA guidelines list engineered flooring less than 3/4" thick, and thin solid wood flooring, among the floors that need that board subfloor replaced or covered with a second layer of panels before installation. The engineered oak and the Lauzon maple we feature here are 19mm (3/4") thick, so they sit outside that list, although the board subfloor still has to pass the flatness check above.
Overlaying the old floor instead of removing it changes the plan another way, because the finished level rises. That height shows up at door casings and where the hall meets bathroom tile. A flat, sound existing floor may be overlaid and the removal step skipped; a floor that rocks or has been patched in strips usually comes out first. Our post on installing flooring over old hardwood walks through the height and flatness questions in more detail.
Plank width, thickness and the rooms in a 1,000 sq ft semi
One measurement decides more about how a finished floor reads than any other: the width of the room.
Narrow rooms and plank width
Take a front room ten feet across. Laid in 6 1/2" planks, that is about 18 full-width rows across the floor; laid in 4 1/4" boards, it is about 28 full-width rows. The wider plank leaves fewer long seams in a small room, while the narrower board sits closer to the look of the strip floors found in older houses. Slate and Cocoa share one build, a 2mm oak top layer on a 6 1/2" plank, and one box price.
Thickness is a separate question from width. The engineered and solid boards are both 19mm (3/4") thick, so compare that with the floor coming out: the difference tells you early whether door clearances and the step up to a tiled bathroom will change. The SPC plank is thinner at 6mm, carries a 12mil wear layer and is sold with an IXPE pad, so no separate underlay roll is needed with that floor.
Basements and back rooms
Below grade, the choice gets simpler. The City of Toronto basement flooding guidance states that "Every home is at risk of basement flooding, even if it has not happened before." A floor listed as waterproof is the practical pick for a basement room, a side entrance or a back addition that has ever taken on water. Our Riche Blonde Sand Oak SPC plank is listed as waterproof, has its pad included and goes down as a click-lock floor rather than being nailed. The same City page notes that up to $6,650 per property is available for eligible flood protection work, so read that program's own eligibility rules before counting on it.
When the old floor is worth keeping
Strip hardwood that is worn but sound can be worth bringing back instead of replacing, and keeping it preserves the proportions of an old room. Our guide to refinishing hardwood floors versus replacing them works through both options with example room sizes. Two things tip the decision in these houses: how much wood is left above the tongue after earlier sandings, and whether the floor has already been patched in strips. Where a new floor is thicker than what comes out, door shaving becomes part of the job and is priced after we see the doors.
Material cost for a 1,000 sq ft main floor
A 1,000 sq ft main floor is a realistic semi footprint and a convenient size for budgeting. Boxes are sold whole, and our quote process adds a 5% allowance for the cuts and offcuts of a real installation, so the order covers more area than the room measures. The arithmetic is short: 1,000 x 1.05 gives 1,050 sq ft to order, then divide by the coverage per box and round up. That works out to 52 boxes of engineered oak at 20.24 sq ft per box, or 62 boxes of the maple at 17 sq ft per box, and the boxes multiplied by the box price give the material line.
| Floor | Boxes for 1,050 sq ft | Material before tax | Material per sq ft of room | Material with 13% HST |
|---|---|---|---|---|
| Slate European oak engineered | 52 boxes | $4,976.92 | $4.98 | $5,623.92 |
| Lauzon Essential hard maple solid | 62 boxes | $6,187.60 | $6.19 | $6,991.99 |
The maple order costs $1,210.68 more than the oak before tax. Labour, removal, trim and delivery sit outside these numbers and are quoted for your rooms and your existing floor.
The maple costs $5.87 per sq ft against $4.73 for the oak, and it is also the narrower board at 4 1/4" wide. Both share the same thickness, so the choice between them comes down to species, board width and budget.
Cocoa is the same floor as Slate in a different colour. In a narrow room, colour changes how the floor reads against the trim: a dark board beside dark baseboard looks heavier, while a lighter board with pale trim keeps the room feeling open. If you are pairing new boards with original trim, bring a piece of it along when you choose the colour.

Frequently asked questions about east-end flooring
What flooring suits an old semi or worker cottage in East York?
On a main floor with a wood subfloor that passes a flatness check, a nailed engineered oak plank or a solid maple board fits well, at $4.73 and $5.87 per sq ft respectively in material. For a basement or a back room that has taken on water, the waterproof SPC plank at $2.66 per sq ft is the practical choice.
Do I have to replace the subfloor before the new floor goes down?
Not automatically. It has to be flat within the NWFA flatness tolerance, and a board subfloor needs replacing or a second layer of panels for the floor types NWFA lists, such as engineered boards under 3/4" thick. If the straight edge shows dips beyond tolerance, levelling or repair is priced once we have seen the floor.
How many boxes will a 1,000 sq ft main floor need?
With the cutting allowance included, plan on 52 boxes of the engineered oak or 62 boxes of the hard maple. The cutting allowance and whole boxes are why the material line lands at $4,976.92 or $6,187.60 before tax, a little more than the per-square-foot price multiplied by the room area.
Which plank width works better in a narrow room?
It depends on how many seams you want to see. A 6 1/2" plank gives roughly 18 full-width rows across a ten-foot room and a 4 1/4" board gives roughly 28, so the wider plank looks calmer in a small front room and the narrower board matches the look of original strip floors.
Should I refinish the old floor or install new boards?
Refinish when the existing strip floor is sound and still has enough wood above the tongue. Choose new boards when the old floor has been patched heavily, when you want a different species, width or colour, or when the room is below grade and needs a waterproof floor.
