The local picture

Why Scarborough homes need window replacement sooner than most

Scarborough’s housing stock works against old windows. Much of Bendale, Wexford, Clairlea, and Agincourt was built between the 1950s and the 1970s. If your home still has original or second-generation windows, they were built for a different era of energy prices.

Then there is the lake. Homes near the Scarborough Bluffs, Guildwood, and West Hill take wind off Lake Ontario for half the year. Wind finds every failed seal. Add freeze and thaw cycles that flex frames every winter, and you get the classic signs:

Condensation or fog trapped between panes of glass

Frames that are soft, peeling, or rotting at the corners

Windows that stick, will not lock, or will not stay open

Cold spots and drafts you can feel from a metre away

Heating and cooling bills that climb every year

25%

Why it matters

of a home's heat loss can go straight through its windows and doors, by Natural Resources Canada's estimate. Replacing leaky units with energy efficient windows is one of the few home upgrades that pays you back every single month.

Real numbers

Window replacement Scarborough cost: real numbers

Prices vary with size, style, glass package, and how the old window comes out. But you deserve ballpark numbers before anyone visits your home. Typical installed prices in the Ontario market look like this:

Window replacement cost per window

Window type	Typical installed price
Slider or single hung, vinyl	$450 to $900
Double hung, vinyl	$600 to $1,200
Casement, vinyl	$700 to $1,500
Picture window	$500 to $1,200
Awning window	$650 to $1,400
Bay or bow window	$1,800 to $5,000+

Door replacement cost per door

Door type	Typical installed price
Entry door, installed	$1,500 to $4,500
Sliding patio door, installed	$1,800 to $5,500

A word about cheap window replacement

Cheap window replacement offers exist in Scarborough, and some are fine. But a bargain window with a sloppy install leaks like an old window within a few winters. The install matters as much as the unit. If one quote comes in far below the others, ask what is missing. Usually it is the capping, the disposal, the warranty, or the insurance.

A whole-home project on a typical Scarborough bungalow with 8 to 12 openings usually lands between $8,000 and $22,000. Treat these as planning numbers, not promises. Your written quotes are the real prices, and that is exactly why you want 3 of them.

What moves the price up or down

Full frame vs retrofit.

A retrofit insert keeps your existing frame and costs less. A full frame replacement strips everything to the rough opening. It costs 15 to 30 percent more and is the right call when frames are rotten.

Glass package.

Double pane is standard. Triple pane adds roughly 10 to 15 percent and cuts noise, which matters near Kingston Road, Highway 401, or the GO line.

Coatings and gas fills.

Low-E coatings and argon are inexpensive and almost always worth it in our climate.

Floor height.

Second-storey and above may need more labour or equipment.

Capping and finishing.

Exterior window replacement work often includes aluminum capping to protect the outside trim. Confirm it is in the quote.

Bundle the doors

Doors get replaced at the same time for a reason

Around half of Scarborough window projects add at least one door. There is a practical reason. The crew is already there, and bundling window and door replacement into one job usually earns a better package price than doing them a year apart.

Entry doors. A new insulated steel or fibreglass entry door fixes the draft you feel in the hallway every winter and updates the whole front of the house.

Sliding patio doors. Old patio doors are famous heat leaks. Modern ones glide on better hardware and carry double or triple pane glass.

Garden doors. French-style doors that swing open, a popular swap for tired sliders.

If doors are the bigger pain point, read about door installation and replacement, then request one combined quote.

Rebates and financing

Rebates, grants and financing in Ontario

You may not have to carry the whole cost yourself. As of mid 2026, three programs matter for Scarborough homeowners. Program rules change, so confirm current details before you sign anything.

Home Renovation Savings Program. Ontario's provincial rebate program pays $100 per opening when you replace windows or doors with Energy Star certified models, which you probably wanted anyway.

Canada Greener Homes Loan. The federal government offers interest-free financing from $5,000 up to $40,000 for eligible energy retrofits, including energy efficient windows. It requires an energy audit before and after the work.

Installer financing. Most established window companies offer monthly payment plans. Ask each of your 3 quotes to include a financing option so you can compare the real cost of borrowing.

Ask each installer to walk you through the paperwork. The good ones handle rebate documentation every week and will tell you plainly which government grant or rebate your project qualifies for.

The comparison checklist

How to pick between your 3 quotes

You will have 3 written quotes in hand. Here is the checklist Scarborough homeowners should run every quote through. Our screening covers the basics, but the final choice is yours, so verify for yourself too.

Read the reviews yourself.

Look up each company's Google reviews and HomeStars profile. Read the 3-star reviews, they are the honest ones. Look at how the company answers complaints.

Confirm insurance and workers' compensation coverage.

Ask for proof of liability insurance and a workplace safety clearance certificate. If an uninsured worker is hurt on your property, that can become your problem.

Compare the warranty, not just the price.

You want two warranties in writing: one on the window itself (25 years or lifetime is the standard among quality manufacturers) and one on the installation labour (look for 2 years minimum, 5 or more is better).

Ask who actually installs.

Employees or subcontractors? Subcontracting is common and can be fine, but the warranty should still come from the company that quoted you.

Get the scope in writing.

Removal, disposal, capping, caulking, interior trim, and cleanup should all be listed. "Supply and install" with no detail is how disputes start.

Watch the deposit.

In Ontario, a typical deposit is 10 to 30 percent. Be careful with anyone demanding most of the money up front.

Consumers who compare 3 written quotes routinely save four figures on a whole-home project versus taking the first offer. Direct comparison is your leverage, use it.

After the form

What happens after you request a quote

Here is the timeline, so nothing surprises you.

Within 1 business day.

Your free in-home consultations get booked, up to 3 of them.

The home visit, about 45 to 90 minutes.

The estimator measures each opening, checks the frames, and talks through styles and glass options. You get a written quote, either on the spot or within a few days.

Final measure.

Once you pick a company, a technician re-measures every opening to the millimetre. Your windows are then manufactured to order, most made right here in Canada.

Manufacturing, typically 4 to 8 weeks.

Custom builds take time. This is normal, not a stall.

Installation day.

A typical crew replaces 8 to 12 retrofit windows in 1 to 2 days. Full frame jobs take longer. The crew should leave your home clean and haul away every old unit.

The walkthrough.

Open, close, and lock every window before the crew leaves. Get your warranty documents before the final payment.

Before the crew arrives

How to prepare for installation day

A little prep makes the install faster and protects your stuff. Your installer will send their own checklist, but this is the usual list.

Clear a path. Crews carry windows through the house all day. Move furniture about a metre back from each window and clear hallways and stairs.

Take down coverings. Remove curtains, blinds, and anything hanging near the openings. Take pictures and shelves off the walls beside each window, since removal can shake the drywall.

Cover what stays. Installers lay drop sheets, but dust travels. Throw an old sheet over the sofa and unplug electronics near the work.

Plan for pets and kids. Doors stay open while crews move in and out. Book the dog a day at daycare or set up a closed room away from the work.

Check outside access. Unlock the gate, move the cars off the driveway, and trim any shrubs blocking a window.

On the day, one crew member should walk the job with you first. Confirm the count, the styles, and which opening gets which window before anyone lifts a pry bar.

FAQ

Frequently asked questions

Straight answers on window replacement costs, rebates, and timing for Scarborough homeowners.

What is the average cost of a standard replacement window?

In the Ontario market, a standard vinyl replacement window runs about $450 to $1,500 installed, depending on style and size. Sliders sit at the low end and casements at the high end. A good planning average for a mid-size vinyl window with installation is $800 to $1,000.

Is there a government grant for window replacement in Ontario?

Yes, help exists, though the shape of it changes. The original federal Greener Homes grant closed to new applicants in 2024. As of mid 2026, Ontario's Home Renovation Savings Program offers a $100 rebate per opening for Energy Star certified windows and doors, and the federal Canada Greener Homes Loan provides interest-free financing up to $40,000 for eligible retrofits. Your installer should confirm current eligibility during your quote.

What is the average cost to replace windows in Ontario?

For a whole home, most Ontario projects land between $700 and $1,300 per window installed once you average across styles. A 10-window home typically totals $8,000 to $18,000 with mid-range vinyl windows, and more with triple pane glass, full frame work, or bay and bow units.

How much should I expect to pay for windows?

Budget $500 to $900 per opening for basic sliders and single hung units, $700 to $1,500 for casements and double hung windows, and $1,800 or more for bay, bow, and specialty shapes. Expect the quote to also list capping, disposal, and taxes. If it does not, ask why.

What does Home Depot charge to install replacement windows?

Home Depot prices window installation by project through its home services arm, so there is no flat public rate. Homeowners generally report all-in prices in the same range as dedicated window companies, roughly $600 to $1,500 per standard window with installation. The trade-off is that big-box work is done by subcontractors. A local window contractor quoting against 2 competitors often sharpens the pencil further, which is the point of comparing.

What time of year are windows the cheapest?

Late fall through winter. Window companies discount in the slow season to keep crews working, and installers can swap windows in the cold without exposing your home. You will often save 5 to 15 percent versus peak spring pricing, and your project starts sooner because the manufacturing queue is shorter.

Are you the company that installs the windows?

No. Drafty is a lead matching service for home window replacement in Scarborough and the GTA. We screen local installers, you tell us about your project, and we introduce you to up to 3 that fit. The contract, the warranty, and the workmanship are between you and the installer you choose. Our job is making sure the companies we introduce are worth your time.

The homeowner’s guide

The deep detail for Scarborough homeowners

For homeowners who like to research before anyone visits. Skim the headings and read what applies to you.

Know the styles

Window styles Scarborough installers quote most

Your quote will name the exact style, so here is what each one means in plain language.

Casement windows

Casement windows crank open outward like a door. They seal tighter than almost any other style because the wind actually presses the sash against the frame. That makes them the workhorse choice for wind-exposed streets near the Bluffs. They are the most common recommendation for bedrooms and living rooms.

Double hung and single hung windows

Both slide vertically. In a single hung window only the bottom sash moves. In a double hung window both sashes move, and most tilt inward so you can clean the exterior glass from inside. Double hung window replacement is popular in older two-storey Scarborough homes because you never need a ladder to clean the second floor.

Slider windows

Slider windows move side to side on a track. No crank, no moving parts to wear out, and a lower price than casements. They suit wide, short openings, which is why you see them all over Scarborough's postwar bungalows and basements.

Awning windows

Awning windows hinge at the top and open outward from the bottom. You can leave them open in the rain and the glass sheds the water. They pair well above a picture window or in bathrooms and basements.

Bay and bow windows

Bay windows use 3 panels that project out from the wall. Bow windows use 4 or 5 panels in a gentle curve. Both add real floor space, a seat ledge, and a lot of light. They cost more than flat windows, and they change the face of your home, so get more than one quote before you commit.

Picture windows

Picture windows do not open. Because there are no moving parts, they are the cheapest per square foot and the most airtight. A common combo in Scarborough living rooms is one large picture window flanked by two casements.

Custom shapes

Angles, circles, arches, and oversized units are all made to order. Every reputable window company measures your openings and builds each unit to fit, so custom shapes are a normal quote line, not an exotic request.

Every crew that quotes a Drafty project installs the full range of replacement windows. For the step-by-step on the installation side, our window installation page covers the process in detail.

Frame materials

Vinyl, wood, or aluminum frames?

Nearly every quote you receive in Scarborough will lead with vinyl windows, and for good reason. Here is how the three materials compare in our climate.

Vinyl. The value leader. Vinyl never needs painting, shrugs off rain and salt air, and insulates well. Quality vinyl frames are fully welded at the corners, not screwed. Expect most of your quotes to be vinyl, and expect the longest warranties here too.

Wood. Beautiful and warm, and the natural fit for heritage homes in Birch Cliff or Cliffside. The trade-off is upkeep. Wood needs paint or stain every few years, and it costs 40 to 100 percent more than vinyl. Many homeowners split the difference with wood inside and an aluminum-clad exterior.

Aluminum. Strong and slim, but metal conducts cold. Older aluminum frames are a big source of winter condensation. Modern versions use thermal breaks, and they still trail vinyl on insulation for the price.

If you are unsure, ask each estimator to quote the same opening in two materials. Seeing the price gap on paper makes the decision fast.

Below grade

Basement windows and egress rules

Replacing basement windows in Scarborough comes with one extra rule worth knowing. If a basement room is used as a bedroom, the Ontario Building Code requires an egress window: an opening large enough for a person to escape through in an emergency, generally at least 0.35 square metres with no dimension under 380 mm.

This matters if you have a basement apartment or plan to create one. A window contractor who works in Scarborough regularly will flag egress requirements without being asked, and can cut and enlarge the opening as part of the job. If an estimator quotes a bedroom-sized basement without mentioning egress, that is a red flag worth raising.

Basement swaps are also the cheapest windows on the quote. Small sliders down low often come in under $500 installed, so they are an easy add-on to a main-floor project.

The smaller fix

Full window replacement or just the glass?

If one pane is foggy but the frame is solid, window glass replacement in Scarborough can cost $200 to $600 for a new sealed glass unit instead of $1,000+ for the whole window. It is the right fix for a newer window with one failed seal.

It is the wrong fix when the frame itself leaks air, the hardware is failing, or the window is 20+ years old with single pane or early double pane glass. New glass in a leaky frame is a new engine in a rusted car. Tell the estimator you are open to either fix, and ask them to justify the recommendation. An honest one sometimes talks you into the smaller job.

Timing the buy

When is the cheapest time to replace windows?

Late fall and winter are usually the cheapest time of year to buy. Demand drops when it gets cold, so companies discount to keep their crews busy. Modern installers work year-round and do one opening at a time, so your house never sits open to the weather.

Spring and early summer are the busiest and priciest season, and manufacturing queues stretch longest then. If you can plan ahead, get quotes in October or November. If your windows are actively failing, do not wait for a season. One more winter of heat loss can cost more than the discount you are chasing.

The straight answer

Who pays us, and why your quotes are free

We get paid by the installer when we send them a real homeowner. You never pay us anything. Because we only get paid for good matches, we have every reason to keep bad companies out of the network.

The measuring, manufacturing, and window installation are done by the local company you pick. The contract and the warranty sit between you and them, and our job is making sure every company we introduce is worth your time.
