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. You deserve ballpark numbers before we ever visit 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 a quote you get elsewhere comes in far below ours, 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 quote is the real price, priced against your actual openings.

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.

Every quote we write for exterior work includes aluminum capping to protect the outside trim.

Bundle the doors

Doors get replaced at the same time for a reason

Around half of the Scarborough projects we quote add at least one door. Crews are already on site, and bundling windows and doors 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 units 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 we 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 we spec by default 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.

Financing options. We offer monthly payment plans on request, so ask us to include a financing option with your quote and compare the real cost of borrowing.

The payoff

A sealed frame does not just stop the draft. It stops you noticing the window at all.

What we hold ourselves to

The standard behind every quote we write

Anyone with a pickup truck and a caulking gun can call themselves a window contractor. Here is what separates a written Drafty quote from a number scribbled on a business card.

A written warranty on the labour, not just the product.

You get two warranties in writing: one on the window itself (25 years or lifetime, standard on the product lines we spec) and one on the installation labour, separate from the manufacturer's.

One team, start to finish.

The people who measure your home manage the project through to the walkthrough. No hand-off you have to chase down.

The full scope, in writing.

Removal, disposal, capping, caulking, interior trim, and cleanup are all listed on your quote before you sign. No vague "supply and install" line.

A deposit that makes sense.

We do not ask for most of the money up front. A reasonable deposit protects both sides; anything more is a red flag on any quote you get, not just ours.

We hold ourselves to that standard on every project, so you get one strong quote instead of guesswork.

How it works

What happens after you request a quote

Here is the timeline, so nothing surprises you.

We book your free in-home visit.

The home visit, about 45 to 90 minutes.

We measure each opening, check the frames, and talk through styles and glass options. You get a written quote, either on the spot or within a few days.

Final measure.

Once you approve the quote, we re-measure 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.

8 to 12 retrofit windows typically go in over 1 to 2 days. Full frame jobs take longer. We leave your home clean and haul away every old unit.

The walkthrough.

We open, close, and lock every window with you before we leave. You get your warranty documents before final payment.

Before we arrive

How to prepare for installation day

A little prep makes the install faster and protects your stuff. We send our own checklist before your install date, but this is the usual list.

Clear a path. Windows move 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. Drop sheets go down, 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 windows 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, we walk the job with you first. We 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. We confirm current eligibility during your free estimate.

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. Our quotes also list capping, disposal, and taxes; if a quote you get elsewhere 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. Ask any installer, ours included, who is actually doing the work on install day and whether that crew carries their own insurance.

What time of year are windows the cheapest?

Late fall through winter. Demand drops in the cold months, so pricing softens to keep crews working, and installs happen in the cold without exposing your home for long. You will often save 5 to 15 percent versus peak spring pricing, and your project starts sooner because the manufacturing queue is shorter.

Is the quote really free?

Yes. There is no cost and no obligation to get a written quote from us. You decide if and when you move forward.

Know the styles

Window styles we quote most in Scarborough

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, and our 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. We quote a lot of double hung replacements in older two-storey Scarborough homes, since 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 we walk through the design with you before we quote it.

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. We measure your openings and quote each unit to fit, so custom shapes are a normal line item, not an exotic request.

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 we write in Scarborough leads 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. The vinyl frames on our quotes are welded at the corners rather than screwed, and carry the longest warranties we offer.

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 us 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. We work in Scarborough every week, so we flag egress requirements without being asked, and can price cutting and enlarging the opening as part of the job. If anyone 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 us you are open to either fix, and we will tell you honestly which one your windows need, even when the smaller job costs less.

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 pricing softens to keep crews busy. Installs run year-round, 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 your quote 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

Why we manage every project start to finish

We do not hand your project off partway through and hope whoever picks it up next knows what was promised. We manage your project from the first measure through the final walkthrough, which is why the warranty on the labour means something.

The measuring, the quoting, and the installation itself all sit under one written quote, so the contract, the warranty, and the follow-up all sit in one place: with us.
