Window Replacement Cost in Toronto: What You Will Actually Pay in 2026
You can feel it every winter. Cold air slides across the living room floor. Water beads on the sills. The furnace runs longer than it should. You know the windows are done. What stops you is not the decision. It is the fear of the number. Every window company gives you a different answer, and none of them will just say what it costs.
This guide fixes that. You get real Toronto price ranges for every common window type and size. You get the labour numbers and the hidden costs installers rarely mention up front. You also get simple math to estimate your own project before anyone sets foot in your home.
2 minutes. A real number in front of you this week.
The quick answer
Average window replacement cost in Toronto
Here is the quick answer. Most Toronto homeowners pay $800 to $1,800 per window, installed, for standard vinyl windows. Specialty windows cost more. Whole-home projects usually land between $8,000 and $22,000. The spread depends on how many openings you have and what you put in them.
| Project size | Installed cost (2026) |
|---|---|
1 standard vinyl window | $800 to $1,800 |
5 windows (small bungalow or condo) | $4,500 to $9,000 |
8 to 10 windows (typical semi or detached) | $7,500 to $16,000 |
12 to 15 windows (larger detached home) | $11,000 to $25,000 |

Why the ranges are wide
Four levers set your number
The cost of window replacement in Toronto rests on four things:
The size of each opening
The window type
The material and glass package
How much work it takes to get the old window out and the new one in square
The rest of this guide breaks down each one. By the end, you can place your own home inside these ranges with confidence.
By window type
Toronto window replacement costs by type
Window type moves the price more than most people expect. A fixed pane of glass is cheap to build and fast to install. A window that cranks open, seals tight, and locks in three places is not.
| Window type | Installed, per window |
|---|---|
Fixed or picture window | $600 to $1,500 |
Slider window | $700 to $1,400 |
Single hung | $750 to $1,500 |
Double hung | $850 to $1,800 |
Awning window | $900 to $1,900 |
Casement window | $950 to $2,000 |
Basement or egress window | $2,500 to $5,000 |
Bay or bow window | $2,500 to $6,000+ |
Notes from real Toronto quoting patterns
Casement windows are the most popular replacement windows in the Toronto area. They seal tighter than sliders and shrug off wind-driven rain. You pay roughly $200 to $400 more than a slider of the same size.
Egress windows cost more because of concrete cutting. A code-compliant basement bedroom opening often costs more to cut than the window itself.
Bay and bow windows are structural projects, not window swaps. Budget at the top of the range if yours needs a new support frame or roof skirt.
By size
Window prices by size
Size matters as much as type. Two casement windows from the same brand can differ by $600 on size alone. Here is how window prices by size break down in Canada for a standard vinyl unit, installed:
| Approximate size | Installed cost |
|---|---|
Small (up to 12 sq ft) 24" x 36" bedroom window | $650 to $1,100 |
Medium (12 to 20 sq ft) 36" x 60" living room window | $900 to $1,600 |
Large (20 to 32 sq ft) 48" x 72" picture window | $1,300 to $2,400 |
Extra large (32+ sq ft) 72" x 72" picture window | $1,800 to $3,200 |
Oversized (4x8 and up) 48" x 96" fixed unit | $2,200 to $4,000 |
Two size questions come up all the time, so here are direct answers. A 72 x 72 picture window cost in Toronto runs $1,800 to $3,200 installed. Glass that large is heavy, often needs tempering, and takes a two-person crew to set. A 4x8 window price lands around $2,200 to $4,000 installed for a fixed unit. It costs more if it opens.
You may also see window prices by size at Home Depot and other big-box stores that look lower. Read the fine print. Those are usually supply-only prices for stock sizes. Add custom sizing, delivery, disposal, and professional window installation, and the totals rise. In the end they land close to what a dedicated window company quotes.

The anchor number
is roughly what a standard replacement window costs installed in Toronto: a mid-size vinyl casement with low-e, argon-filled double pane glass. Hold that number against every table in this guide.
Line by line
The full cost breakdown
Every window quote is really three numbers stacked together. The window itself, the labour, and the extras. Pull them apart and quotes get much easier to compare.
01
Window material costs (supply only)
The unit itself is usually 60 to 70 percent of your total. Frame material is the biggest lever:
Vinyl windows: $300 to $1,200 per window. Vinyl is the default in Toronto for good reason. It insulates well, never needs painting, and costs the least. Around 8 in 10 replacement projects here use vinyl.
Fiberglass: $600 to $2,000 per window. Stronger than vinyl and more stable in big temperature swings, with slimmer frames. A common upgrade on modern homes.
Wood or wood-clad: $900 to $3,000+ per window. The premium look. Often required on heritage-listed Toronto homes. Expect ongoing upkeep.
Glass packages stack on top. Double pane with low-e coating and argon gas is the baseline for energy efficient windows in our climate. Triple pane adds roughly $100 to $300 per window. It pays off most on north-facing walls and busy streets, where the extra quiet matters.
02
Labour and installation costs
The labor cost to remove and replace windows in Toronto runs $250 to $800 per window for a standard retrofit. Full-frame work costs more. Installation is where cheap quotes go to die, so know what you are paying for:
Retrofit installation ($250 to $500 per window): the new window goes into your existing frame. Faster and cheaper. The right call when your frames are sound and square.
Full-frame installation ($500 to $800+ per window): the installer strips the opening down to the studs. They check for rot, re-insulate, and rebuild the trim inside and out. It costs 30 to 50 percent more. It is the right call when frames are rotted, warped, or leaking air.
If an installer quotes retrofit without probing your existing frames, that is a flag. Retrofit over rot just hides the problem behind new vinyl.
03
Additional costs to budget for
These are the line items that turn a $1,000 window into a $1,400 window on the final invoice:
Aluminum capping of exterior trim
$50 to $150 per window
Old window disposal
$20 to $50 per window, sometimes bundled
Interior trim and casing replacement
$100 to $300 per window
Custom exterior colours
10 to 25 percent upcharge on the unit
Rot or structural repair
$200 to $1,000+ per opening, found on removal
Permits
usually not needed for same-size replacement in Toronto. Enlarging an opening or adding an egress window triggers a building permit at a few hundred dollars.
Read before you sign
Hidden costs to watch out for
An honest window contractor puts everything above in writing. A pressure-driven one leaves gaps and fills them in after you sign. Watch for these:
“Starting at” pricing. The $499 window in the ad is a small slider in builder white with basic glass. Your actual openings will not cost that.
Rot found mid-job. Fair installers put a per-opening rot rate in the contract before work starts. That way a surprise never becomes a blank cheque.
Brick-to-brick disputes. Toronto's older brick homes often need brick-to-brick, meaning full-frame, replacement. If the quote assumed retrofit, the change order stings.
Second-storey and access charges. Some companies add fees for upper floors, tight laneways, or removing window air conditioners. Ask up front.
Disposal and capping sold separately. Two quotes can differ by $1,500 on a 10-window job purely on what is bundled.
The fix is simple. Get every quote itemized per window. Installation type, glass package, capping, disposal, and rot contingency should all be spelled out. The quote checklist near the end of this guide gives you the exact list.
Real layouts
Example Toronto project budgets
Ranges are useful, but budgets are built from real layouts. Here are three example budgets using the per-window numbers above. Your home will differ. This is the estimating method, not a promise.
01
Average cost to replace windows in a 3 bed house
A typical 3 bedroom Toronto semi has 8 to 10 windows. Three bedroom windows, a bathroom window, two or three main floor windows, a kitchen window, and one or two basement windows. At standard vinyl pricing, the average cost to replace windows in a 3 bed house lands between $8,000 and $15,000 installed. Upgrade to triple pane and add capping, and you are closer to $12,000 to $18,000.
02
Average cost to replace windows in a 4 bed house
A 4 bedroom detached home usually carries 12 to 15 openings. That often includes a bay window and a large picture window. The average cost to replace windows in a 4 bed house in Toronto runs $12,000 to $25,000 installed. The bay window and any egress work drive the top end.
03
Condo or small bungalow
Five standard openings in vinyl typically total $4,500 to $9,000. Condo owners, check with your board first. Many Toronto condo boards control window replacement or run building-wide programs. You may only be on the hook for interior parts.
Back-of-envelope math
How to estimate your own cost before getting quotes
You do not need a fancy tool to get close. Every window replacement cost estimator works from the same basic math. You can do it on the back of an envelope:
01
Count your openings. Walk the house, inside and out. Include the basement.
02
Assign each a base price. Use $1,100 for a standard opening, $1,600 for large ones, $3,500 for bays and egress windows.
03
Add 15 percent for capping, disposal, and small surprises.
04
Add 10 to 15 percent more if your home is older than 40 years. Full-frame work and rot repair get likelier with age.
That total will land within about 20 percent of your real quotes. If you prefer a tool, any window replacement cost calculator for Toronto will run similar assumptions. So will a broader window cost calculator for Canada. Treat the output as a planning number, not a price. The same goes for a window glass replacement cost estimator if you only need sealed units swapped for foggy glass. That job runs $300 to $600 per pane when the frame is still healthy.
The only number that holds is a written, itemized quote from a window contractor who measured your openings in person.
That is the number you can plan around, and we can get you one for free.
Easier on the budget
Rebates, programs, and financing
Two pieces of good news for Ontario homeowners.
First, window replacement cost in Ontario drops when energy programs apply, as long as you install Energy Star certified units. Program names, amounts, and rules change often. So we keep a dedicated, updated breakdown in our Toronto window rebates guide. Have you heard of a window replacement program in Ontario offering free windows? Read that guide before you sign anything. Real rebates reduce your cost. They do not erase it. “Free window” pitches are a common sales tactic.
Second, most established window companies in Toronto offer financing. Plans usually run 12 to 60 months. On a $12,000 project, that can mean $200 to $400 per month, depending on term and rate. Financing makes sense when the comfort arrives now and the cost spreads out. Just compare the financed total against the cash price so you know what the convenience costs.
Spend smart
How to save money without regretting it
Strategies that actually work
Replace all windows at once. Installers price per project, not just per window. One crew, one trip, one disposal run. Whole-home jobs often price 10 to 15 percent below the same windows done in batches.
Book for late fall or winter. Demand peaks in spring and summer. Crews install year-round in Toronto, one opening at a time, so your house never sits open. Slower months often bring better pricing and faster dates.
Stay with standard operating styles. A casement where you need airflow, fixed panes where you do not. Fixed units cost 30 to 40 percent less than openers of the same size.
Skip the exotic colours. Custom exterior finishes add 10 to 25 percent. White and black stock finishes keep the price down.
Claim every rebate you qualify for. See the rebates guide. The paperwork takes an evening and can return hundreds of dollars per opening.
False economies to avoid
Taking the lowest of three quotes by default. A quote 25 percent under the field usually means something. Retrofit over frames that need full-frame work, a thin glass package, or an uninsured crew. The redo costs more than the savings.
Replacing glass when the frame is failing. New sealed units in a rotted or warped frame buy you 2 or 3 years. Then you pay for windows again.
Going cheap on installation. A $1,500 window installed badly performs worse than a $900 window installed well. Air sealing and squareness are the whole game.
Doing structural work yourself. Window installation ties into your building envelope, flashing, and vapour barrier. Mistakes show up as rot two winters later.

The return
Is it worth the cost? Payback and resale value
Windows are a rare renovation. You feel them every single day, and you recover much of the cost at resale. Three ways the money comes back:
Resale value. Canadian appraisal estimates put window and door replacement recovery at 50 to 75 percent of project cost at sale. Toronto buyers notice new windows. Home inspectors flag old ones.
Energy savings. Natural Resources Canada pegs up to 25 percent of a typical home's heat loss to windows and doors. Moving from failed units to modern energy efficient windows commonly trims heating and cooling bills by 10 to 20 percent. In a Toronto detached home, that is worth a few hundred dollars a year.
Comfort and problem prevention. Ending condensation stops mould at the sills. Ending drafts ends the cold-room problem. Neither shows up on a spreadsheet. Both are why most homeowners say they wish they had done it sooner.
Add rebates on top, and a mid-range project often pays back a large share of its cost within 7 to 12 years, before you count resale.

How to get accurate quotes
Force clarity with this checklist, and the spread collapses into quotes you can actually compare.
Quote checklist
Every quote you accept should state, in writing:
- 01
Price per window, itemized, not one lump sum
- 02
Installation type for each opening: retrofit or full-frame
- 03
Frame material, glass package, and gas fill (look for the Energy Star label)
- 04
Aluminum capping: included or extra, and where
- 05
Old window disposal: included or extra
- 06
Rot repair: a per-opening rate agreed before work starts
- 07
Proof of liability insurance and WSIB coverage for the crew
- 08
Manufacturer warranty on the units, plus a written workmanship warranty on the install
- 09
Deposit terms (be wary of anything above 30 percent up front)
- 10
Start window and estimated duration
Any company that resists itemizing is telling you something. Move on.
The faster route
You can spend two weeks booking sales appointments. Or you can do it once. Tell us about your project through our free quote form. Your openings get measured in person by a crew that already meets every requirement on that checklist. Verified insurance, WSIB coverage, a written workmanship warranty, and a track record we monitor. You get one measured, itemized quote without the 3-hour kitchen-table sales pitch, and if anything is not right, you tell us and we make it right. The quote costs you nothing. Crews pay us the way they would pay for advertising, and that never changes your price.
If your project includes doors, the same quote covers entry door replacement too. Bundling window and door replacement into one project usually beats pricing them separately.
