Door Installation in Toronto

Renovator Toronto installs interior and entry doors across Toronto. An interior door installed runs $630 to $1,800 with a Toronto average of $1,200, dropping to $130 to $1,300 where the existing frame stays. Entry doors average $1,200 installed, with standard single units from $200 to $800 and material driving the spread: steel $200 to $1,800, fibreglass $200 to $2,600 and wood $660 to $4,000.

Why door prices vary so widely

Slab or pre-hung

A pre-hung door arrives in its own frame and adds $60 to $260 over a slab, but it is the only reliable way to get a door hanging square in an old Toronto opening that has moved. A slab into a racked existing frame never closes properly.

Material, on entry doors

Steel runs $200 to $1,800, fibreglass $200 to $2,600 and wood $660 to $4,000. Fibreglass handles Toronto's freeze-thaw swing without moving the way wood does, which is why it dominates replacement work here.

Sidelights and transoms

Sidelights add $900 to $4,000 to an entry door, because the opening grows and the whole assembly has to be structurally supported, flashed and sealed as one unit rather than as a door.

The part that decides the result

An old opening is rarely square

Fifty-eight percent of Toronto households live in a dwelling built before 1981, and in a house of that age the door openings have moved. Framing has shrunk, the house has settled unevenly, and floors are rarely level across a doorway. A door installed into that opening without correcting for it will bind at the top, swing open on its own, or leave a tapering gap along the latch edge. Getting it right means checking the opening for plumb, level and twist, shimming the jamb to correct it rather than to fill it, and adjusting hinge positions so the reveal is even on all three sides. That is why the same door costs $130 in a sound frame and $630 to $1,800 pre-hung in an opening that needs work, and it is the only part of a door installation anyone notices a year later.

Door installation types, priced per opening

Six kinds of door job, quoted per opening.

$630 to $1,800 each

Interior doors, pre-hung

New door and frame set plumb, level and square in the opening, with even reveals and adjusted hinges.

$130 to $1,300 each

Slab replacement in sound frames

New slab hung in an existing frame where the frame is square and sound. The lowest-cost route where it applies.

Average $1,200 installed

Entry and exterior doors

Steel, fibreglass or wood entry door set, flashed, sealed, insulated at the perimeter and weatherstripped.

$900 to $4,000 extra

Entry with sidelights

Wider assembly with structural support, flashed and sealed as a single unit rather than as separate elements.

Rated where required

Basement and suite doors

Doors in a fire separation for a second suite, specified to the rating the assembly requires.

Track and hardware

Closet and pocket doors

Bypass, bifold and pocket doors, with track and hardware fitted so they run without lifting or binding.

What we do on every door

Four steps that separate a hung door from a fitted one.

Check the opening before ordering

Plumb, level and twist measured, and the floor checked across the threshold. That determines whether a slab will work or whether the job needs a pre-hung unit, and it changes the price before anything is bought.

Shim to correct, not to fill

Shims exist to bring a jamb plumb and straight, not to take up a gap. A jamb shimmed only where it is loose leaves a door that binds or drifts, and no amount of hinge adjustment fixes it afterwards.

Weatherseal and insulate exterior perimeters

An entry door is an envelope component. The perimeter gets insulated and air-sealed and the flashing detailed for Toronto's freeze-thaw exposure, because a well-made door in a leaky opening still costs you heat.

Hardware set and tested through the swing

Latch and strike aligned, hinges adjusted, and the door tested through its full swing and at the closed position rather than just checked for a flush face.

Our Process

How a door installation runs

1

Measure and check the openings

Plumb, level, twist and threshold checked at each opening, then a per-door quote that says slab or pre-hung and why.

2

Order to measured sizes

Doors, frames, hardware and any sidelight assembly ordered to the measured openings rather than nominal sizes.

3

Remove and set

Old unit out, opening repaired where needed, then the new door shimmed plumb and square and fixed through the jamb.

4

Seal, trim, adjust

Exterior perimeters insulated, air-sealed and flashed, casing fitted, hardware set and the swing tested, then the walkthrough.

Door installation questions about frames and fit

How much does it cost to install an interior door in Toronto?

Installed, an interior door runs $630 to $1,800 with a Toronto average of $1,200. Where the existing frame is square and sound and only the slab is replaced, it drops to $130 to $1,300 per door.

Should I get a slab or a pre-hung door?

Pre-hung, in most older Toronto houses. It adds $60 to $260 over a slab but it is the only reliable way to get a door hanging square in an opening that has moved. A slab only works where the existing frame is still plumb and straight.

Which entry door material lasts longest in Toronto?

Fibreglass handles roughly 65 freeze-thaw cycles a year without the seasonal movement wood shows, and it runs $200 to $2,600. Steel at $200 to $1,800 is the value option and dents. Wood at $660 to $4,000 looks the way people want and needs the most maintenance.

Do I need a permit to replace a door?

Not for replacement in a single-family home with no change to the size or location of the opening. Creating a new door opening, or enlarging or relocating an existing one, is permit work.

Why does my new door stick or swing open by itself?

The jamb is not plumb. A door that swings open on its own is hanging in a frame leaning slightly in the direction it swings, and one that binds at the top is in a frame that is twisted or out of square. Both are shimming problems from installation, not door faults.
