A new front door in Québec usually costs about ,000 to ,000 for a plain single door, installed. With sidelights or a double door, budget ,500 to ,000 and up.1 Steel sits at the low end, then fiberglass, wood and aluminum.2 These are market ranges from published sources, not Factory Direct prices. We quote after an in-home estimate.
Installed price ranges in Québec, by door setup
How much does a front door replacement cost in Montreal in 2026?
Start with the setup, not the material. Home Depot Canada publishes a Québec table. Prices include labour, interior casing, and removal and disposal of the old door. Taxes are extra.1
| Door setup | Installed range (Québec) | Average |
|---|---|---|
| Single door, primed | $2,000 to $3,000+ | $2,500 |
| Single door + 1 sidelight, painted outside | $2,500 to $4,500+ | $3,500 |
| Single door + 2 sidelights, painted inside and out | $4,000 to $6,500+ | $4,500 |
| Double door, primed | $3,500 to $7,000 | not given |
One Montréal-specific estimate runs wider: $1,425 to $6,650 per door, with $3,325 as the average. The site does not explain how it got those numbers, so treat it as a rough check only.4
The same Home Depot page puts the Canada-wide average at $2,500 for a single door without sidelights.1 Québec’s average for a fiberglass door with one sidelight is $3,500.1
Steel, fiberglass, wood or aluminum: what does each cost?
Sources disagree, so here are two. Both are Québec sources. One includes installation. The other lists the door only.
| Material | Installed (Reno-Assistance, Sept. 2024) | Door only (Soumission Rénovation, Feb. 2026) |
|---|---|---|
| Steel | $1,680 to $1,920 | $200 to $3,000 |
| Fiberglass | $1,800 to $2,280 | $900 to $3,000 |
| Wood | $1,920 to $2,400 | $300 to $5,000 |
| Aluminum | $2,400 to $4,200 | $1,200 to $3,000 |
| High-end door | $3,600 to $5,400 | not listed |
The first column is older, so it runs lower than the Home Depot table.2 The second column is wide because it covers every style and size.3 Use the order, not the exact numbers. Steel is usually the lowest tier. Aluminum is usually the highest.
The second source adds a labour range: $400 to $800 to install. It says the cost rises when the frame must change, and a door with a transom or sidelights can pass $800.3
What makes the price of an entry door go up or down?
Seven things move the quote. Ask each installer to price them one by one.
- Size and layout. A double door, a sidelight or a transom adds product and labour.1 One manufacturer makes an extra-large sidelight built to replace a door plus two standard sidelights.7
- Glass. A decorative glass catalogue we work from lists 49 designs in three price tiers. 29 are in the lowest tier, 14 in the middle and 6 in the highest.7 Privacy is rated on a five-step scale, so you can choose a design that blocks the view from the street.7
- Hardware. Locks, handles and hinges vary. An aluminum door line offers optional multipoint locking, which locks the door at three points.7 Ask whether the lockset is in the price.
- Frame work. A new frame costs more than a slab swap but fixes the weak part of an old entry. More on that below.
- The opening. Brick, stone, a stair landing and an uneven rough opening all add time.
- Finish. Painted, stained or wood-grain finishes cost more than primed. A black outside with a white inside is an option on several steel models.7
- Energy rating. ENERGY STAR labelled doors matter for rebates. See the Rénoclimat section.
Is it cheaper to replace just the door slab?
It can be, but it is rarely the better buy. A slab swap reuses the old frame, so any rot, gap or draft stays. A full pre-hung unit replaces the slab, frame and sill together. Home Depot’s table prices the pre-hung unit.1
A slab swap also blocks the rebate. Québec says replacing a door without its frame is not eligible for Rénoclimat.5
Keep the slab-only option for a sound frame with a plain, standard size. Ask the installer to open the trim and look first.
Brick, stone, plex and balcony doors: what changes?
Most Montréal homes are not a simple wood-frame opening. Tell the estimator which of these you have, because each one changes the work. This section is trade experience, not a published price.
- Brick and stone openings. The installer works around the masonry. The old frame must come out without cracking brick, and the new unit must be sealed back to it.
- Plex and shared entries. Many plexes have a stair or a shared landing outside the door. Tell the installer which way the door opens and how much landing you have. Ask whether the new door can swing the same way.
- Balcony and rear doors. A balcony door is often a patio door or a French door, not a standard entry door. It follows a different price list. See our front entry doors and patio door pages to compare.
Steel or fiberglass door: which one is better for Montreal?
Both work in a Québec winter. Pick by how you use the door and what the climate does to it.
| Steel | Fiberglass | |
|---|---|---|
| Price tier | Usually lowest2 | A step above steel2 |
| Maker claims | ENERGY STAR on the high-performance line, with triple-glazed door glass7 | Makers say it does not rust, warp or rot. Foam core. ENERGY STAR Canada on some lines7 |
| Look | Many modern and classic panel styles, black or white finishes | Six wood-grain textures in one line, stain-ready |
The “maker claims” row comes from manufacturer catalogues. They give no lab numbers we can quote, so ask for the rating label on the model you pick.7
Our rule of thumb: choose steel for the lowest cost and a clean modern look. Choose fiberglass if you want a wood look without wood upkeep. Read our guide to front door replacement in Montreal for the full material comparison. For model choices, see how to choose an entry door.

Does Rénoclimat pay for a new front door?
Possibly, but check your file before you sign. The program changed on October 1, 2026. Québec.ca’s new table pays $300 per window, up to $4,500 for a house and $6,000 for a multi-unit building.6 That table names windows. It does not name entry doors.
Québec’s own page on doors and windows still shows $150 per door or window opening under the old rules.5 Files already evaluated can finish until March 31, 2027.5 The page lists the conditions:5
- The door must be ENERGY STAR certified. Keep the label and the invoice.
- It must go into an existing rough opening.
- Replacing a door without its frame does not qualify.
- An RBQ-licensed contractor must do the work.6
Ask for the door amount in writing from the program before you count on it. Our Rénoclimat checklist walks through the steps.9
How do I compare door quotes?
A low quote that leaves things out is not low. Put the quotes side by side and check these lines.
- Scope. Does it say slab only, or full frame, sill and door?
- Removal. Is disposal of the old door included?
- Hardware. Which lockset, handle and hinges? Is multipoint locking in or out?
- Glass. Which design, which privacy level, which glass type?
- Finish. Primed, painted or stained, inside and out?
- Trim and masonry. Who repairs the interior casing and the exterior edge?
- Licence. Check the RBQ licence in the public registry.8
- Warranty. Get the product and labour terms in writing.
Compare the total with taxes, not the door price alone.
Frequently asked questions
How much does a front door cost in Montreal?
A plain single door installed runs about $2,000 to $3,000 in Québec. Add a sidelight and the range moves to $2,500 to $4,500 or more. A double door runs about $3,500 to $7,000.1
Is fiberglass worth the extra over steel?
If you want a wood look or a door that will not rust or warp, often yes. Published ranges put fiberglass a step above steel, and the ranges overlap.2
How much does door installation cost by itself?
One Québec source lists $400 to $800 for installation. A new frame, a transom or sidelights can push it past $800.3
Do I need a new frame or just a new door?
Replace the frame if you see rot, gaps, drafts or a sagging sill. A slab-only swap is cheaper but does not qualify for Rénoclimat.5
Does the government pay for a new front door?
Rénoclimat has paid $150 per door or window opening under the old rules.5 The October 2026 table lists windows at $300 and does not name entry doors.6 Confirm the door amount with the program first.
Are these prices before or after tax?
The Home Depot Québec table excludes taxes.1 Add GST and QST when you compare a quote with these ranges.
