Nobody asks what a door costs because they are curious. They ask because something has gone wrong: the front door sticks in July and lets a draft through in January, the patio slider takes two hands and a shoulder to move, or the storm door finally gave up. Then the searching starts, and the numbers that come back are all over the map. One page says a door installation runs a few hundred dollars. Another says five figures. Both are technically true, and neither one helps you plan.
So here is the straight version. This guide breaks down what door installation actually costs in Ontario in 2026 by door type, what makes one quote double another, where your money physically goes, and how to read a written quote so you can tell a complete price from a lowball that grows later. We have been installing doors in Windsor and Essex County since 1989, so the ranges below reflect what real jobs look like on real houses rather than a national average scraped off a spreadsheet. If you want the service side of this rather than the pricing side, start with our door installation service in Windsor-Essex.
Door Installation Cost in Ontario at a Glance
The single biggest driver of price is the door type, and the spread between the cheapest and the most expensive door in a typical home is enormous. An interior bedroom door and a wide French patio unit are both “doors,” but they are not remotely the same job. The chart below gives you the installed range for each of the main types we get asked about across our entry door and patio door lineup. Installed means the unit plus the labour to remove the old one, set the new one square, insulate, seal and finish the opening. That distinction is worth holding onto, because most of the low numbers you will find quoted online are door-only prices with the labour stripped out.
Average installed door cost in Ontario by door type
Installed price ranges for 2026. Each bar spans the low and high end of the range, and the white marker shows the midpoint. Installed means the unit plus the labour to remove the old door, set the new one square, insulate, seal and finish the opening.
Read this before you budget from the chart. These are broad Ontario planning ranges, not a price list and not an estimate for your home. Real prices move with door type, unit size, glass package, hardware selection, the condition of the existing opening, and municipal permit and inspection requirements. Two houses on the same street in Tecumseh can land at different numbers for the same door. Only a written, site-specific quote after someone has measured your opening is binding.
What Actually Drives the Price
Door Material
Material sets the floor and the ceiling of your quote before anything else is decided. Steel is the value option: strong, secure, and the least expensive of the exterior choices, though it can dent and it shows wear on a west-facing wall. Fibreglass sits in the middle and is what most homeowners in our area end up choosing, because it holds paint and stain, will not rot or dent easily, and handles the swing from a humid Leamington August to a January freeze without moving much. Wood is the premium: beautiful, heavy, endlessly customizable, and the only material that asks you to refinish it every few years.
Size and Configuration
A door is priced as a unit, not by the square metre, and every extra piece of that unit adds cost. A single 32-inch entry door is the baseline. Add a sidelite and you have widened the rough opening and added a second sealed glass unit. Add two sidelites and a transom above and you are into a custom assembly that may need structural work overhead. Patio doors follow the same logic: a two-panel slider costs less than a three-panel, and a four-panel French configuration with an operating pair plus fixed panels costs more again. Our patio door options page walks through the common configurations.
Glass Package and Low-E / Argon Upgrades
Glass is where a modest door becomes an expensive one. A solid slab with no glass is the cheapest thing you can buy. Add a half-lite, a full-lite, decorative caming, obscure or textured privacy glass, or blinds sealed between the panes, and each step adds real money. Energy performance is its own line: ENERGY STAR units with Low-E coatings and argon fill between the panes cost more than plain double glazing and are also the units that qualify for most efficiency programs. It is the same physics we explain on our replacement windows page, and the same reason we do not sell a bargain glass package.
Condition of the Existing Opening
This is the variable nobody budgets for and the one that most often moves a quote. When the old door comes out, we see what is behind the trim. On a 1950s Windsor bungalow that can mean a rotted sill, a sagging header, water damage in the sheathing, or a rough opening that was never square to begin with. Sometimes it is a 90-year-old brick surround that needs careful handling so nothing cracks. None of that is visible from the driveway, which is exactly why a real quote comes from someone who has looked at your opening and, ideally, why you want a company that can do carpentry repairs on the spot instead of stopping the job.
Hardware and Locking
Hardware is a genuine budget item, not a rounding error. A basic knob-and-deadbolt set is inexpensive. A multi-point locking system that throws at three places along the jamb, a keyless or smart deadbolt, a heavy commercial-grade handleset, a matching finish across a door plus sidelites, or a three-point patio lock all add cost and all add security. Hinges matter too: a heavy wood or triple-glazed door needs beefier hinges than a hollow interior slab. Decide hardware early, because switching finish or lock type after the unit is ordered usually means ordering again.
Finishing and Capping
The last ten per cent of the job is the part homeowners see every day. Outside, that means exterior trim and aluminum capping, bent and fitted so water runs away from the opening rather than into it, plus new brickmould where the old one has failed. Inside, it means casing that matches your existing trim profile, caulking, and either factory finish or a painted or stained finish on site. Colour-matched capping and a stained wood finish cost more than white capping and a primed slab. Skip this work and you get a door that performs but never quite looks finished.
Door Only vs Professionally Installed
The cheapest number you will find online is almost always a door-only price, and it is not comparable to an installed price. A door on a shelf is one component of maybe ten that a working, sealed, weathertight opening requires. Once you add the frame, the removal and disposal of the old unit, the shimming and squaring, the insulating and sealing, the exterior capping, the interior casing, the hardware and the finish, you have a project rather than a purchase. The table below shows exactly which components are covered by which price.
| What’s Included in an Installed Price vs a Door-Only Price | ||
|---|---|---|
| Cost component | Door Only (DIY install) | Professionally Installed |
| The door slab or unit | Included | Included |
| Frame and jamb | Extra cost (slab-only purchases) | Included |
| Removal and disposal of the old door | Not included | Included |
| Shimming and squaring the opening | Not included (your labour) | Included |
| Insulation and sealing | Extra cost (materials) | Included |
| Exterior trim and capping | Not included | Included |
| Interior casing | Not included | Included |
| Hardware and lock | Extra cost | Included (as specified in the quote) |
| Finishing or painting | Extra cost | Included or quoted as an option |
| Warranty coverage | Product warranty only, install not covered | Included — product and workmanship |
The same opening, priced two ways: a door-only price covers one line of this table, while an installed price covers the whole opening including the workmanship warranty.
Here is the part that matters more than the money. A badly installed premium door will underperform a well-installed mid-range one every single time, and it is not a close contest. Door performance is a function of the seal, and the seal is a function of the install. If the unit is out of square by a few millimetres, the weatherstripping only makes contact along part of its length, so you get a draft in the corner no matter how good the glass package is. If the gap around the frame is stuffed with the wrong insulation or nothing at all, you have built a thermal bypass around a door you paid extra to be efficient. If the sill is not properly supported and pitched, water finds the subfloor.
You can see this in the field: doors that stick in humid weather, deadbolts that no longer line up with the strike plate, sliders that jump their track, and condensation forming at the bottom corners. Almost none of that is a manufacturing defect. It is installation. This is why we run in-house crews with no subcontractors and why our installers are SAWDAC-trained, and it is also why our workmanship is backed by our Platinum Warranty rather than pointing you back at the door maker. Have a look at the finished work in our project gallery and pay attention to the capping and the reveals, because that is where the install shows.
Where Your Money Goes
It helps to know roughly how an installed door price splits up, because it tells you which decisions actually move your total. Most of your money is in the unit itself, and the next largest share is skilled labour. Upgrades to glass and hardware are the discretionary slice, the part you control by choosing a full-lite door with decorative glass instead of a half-lite, or a multi-point lock instead of a standard deadbolt. Disposal and finishing round out the job.
Where your door installation dollar goes
Approximate share of a typical installed exterior door price. Knowing the split tells you which decisions actually move your total.
- 45% The door unit itself The slab or patio unit, frame, jamb and factory weatherstripping.
- 32% Labour Removal, shimming and squaring, insulating, sealing, casing and capping.
- 14% Hardware and glass upgrades Locksets, handlesets, hinges, and decorative or Low-E glass packages.
- 9% Disposal and finishing Hauling away the old unit, caulking, paint or stain, and final adjustment.
Two takeaways. Labour is roughly a third of the job, so an unusually cheap installed quote is almost always cutting the labour scope: no capping, no disposal, no interior casing. And if you need to bring a number down, the honest lever is the glass and hardware package rather than the install — trim the decorative glass, keep the Low-E and argon, keep the proper install.
Ontario Rebates and Energy Incentives
Efficiency rebates can meaningfully reduce the net cost of a door replacement, but they come with one consistent condition: the unit almost always has to be ENERGY STAR certified for the Canadian climate zone your home sits in. That is the qualification threshold that trips people up, because a builder-grade door with plain double glazing will not clear it. Doors with Low-E coated glass and argon fill are the ones written into program requirements, which is part of why we stock them as standard rather than as an upsell.
What we will not do here is quote you a rebate amount or a deadline. Program funding, dollar values, application windows and eligibility rules change, sometimes mid-year, and a number published in a blog post is exactly the kind of thing homeowners plan around and then get burned by. Keep your invoice, keep the ENERGY STAR documentation for the specific unit installed, and confirm what is live at the time you buy. We track this and write about it as programs change, so check the current rebate coverage on the Advanced Home Services blog or ask us in the showroom before you place your order.
How to Read a Door Installation Quote
The fastest way to compare two quotes is to check whether each one tells you what you are getting. A single line reading “supply and install front door” with a price beside it is not a quote, it is a number, and it leaves every expensive decision undefined. A complete quote is specific enough that a different installer could read it and build the same job. Here is what it should itemize.
- The exact unit: manufacturer, model, material, size, swing direction, configuration including any sidelites or transom, and the exterior and interior colour or finish.
- The glass package: lite style, whether the glass is Low-E coated and argon filled, obscure or decorative options, and the ENERGY STAR designation if energy performance matters to you.
- Hardware in detail: lockset and handleset make and finish, deadbolt or multi-point locking, hinge grade, and whether a keying or smart lock option is included or extra.
- Labour scope: removal of the existing door, shimming and squaring, insulating and sealing, exterior capping and brickmould, interior casing, and caulking.
- Disposal, permits and site conditions: who hauls the old unit away, who pulls a permit if one is required, and clearly stated hourly or unit pricing for carpentry repairs if rot or a failed header is found once the door is out.
- Warranty terms in writing: what the manufacturer covers on the product, what the installer covers on workmanship, how long each lasts, and whether the coverage transfers if you sell the house.

Frequently Asked Questions
How much does it cost to install an exterior door in Ontario?
For planning purposes, most installed exterior door projects in Ontario in 2026 fall somewhere between roughly $1,400 and $9,000, depending almost entirely on what you choose. A basic steel entry door sits near the bottom of that spread, a fibreglass door with a glass package sits in the middle, and a wide patio unit or a custom wood door with sidelites sits at the top. Site conditions and finishing scope move the number further. Only a measured, written quote is binding.
Is it cheaper to replace just the slab or the whole unit?
Replacing only the slab is cheaper up front and occasionally the right call, but it only works if the existing frame, jamb, sill and weatherstripping are square, sound and dry. If the frame has moved or the sill has rot, a new slab in an old frame will never seal properly and you have spent money without fixing the draft. A full unit replacement resets the whole opening. Our door replacement page covers when each approach makes sense.
Does installation cost more for a bigger opening?
Yes, on both sides of the invoice. A larger unit costs more to manufacture, and it costs more to install because it is heavier, often needs two installers, and may require structural work if you are widening the rough opening rather than replacing like for like. Widening an opening usually means a new header, and depending on the wall it may need a permit. Patio doors and units with sidelites or transoms carry the same premium.
Do I need a permit to replace a door?
Usually not for a straight like-for-like replacement in an existing opening. Where a permit typically comes into play is when you change the structure: cutting a new opening, widening an existing one, or altering a header or load-bearing element. Rules and interpretations vary by municipality, so Windsor, LaSalle, Amherstburg and Kingsville may not treat the same job identically. We check with the local building department before the job starts rather than after.
How long does door installation take?
A straightforward single entry door replacement is normally a same-day job, often a few hours from removal to final adjustment. A patio door, a unit with sidelites and a transom, or anything requiring carpentry repairs to the opening can take a full day or occasionally two. The longer part of the timeline is almost always the manufacturing lead time on the unit itself, not the install, especially on custom sizes, colours or glass packages.
Can I supply my own door?
Some installers will fit a homeowner-supplied door, but be clear about what you are giving up. If the unit is the wrong size, arrives damaged, or is missing hardware, that becomes your problem and your delay, and the workmanship warranty cannot cover a product nobody vetted. We supply and install as one accountable job so there is a single point of responsibility for the door and the opening. See where we work across our Windsor-Essex service areas.
Get a Real Number for Your Door
Ranges are useful for planning and useless for deciding. The only figure worth acting on is the one that comes after somebody has measured your opening, looked at the sill and the header, listened to what you actually want the door to do, and put it in writing. We have been doing that around Windsor, LaSalle, Tecumseh, Amherstburg, Essex, Lakeshore, Kingsville and Leamington since 1989, which is 37 years of openings on houses like yours, with our own crews and no subcontractors. Come see and operate the units in our showroom, or book a free door installation quote and we will bring the numbers to you.
