Replacement Windows Calculator | Instant Cost Estimate

Southern Ontario:

The trusted choice. Canadian made.

Most online window "calculators" ask a handful of generic questions and hand back a single number. Canadian Choice's calculator is built differently: it walks you through your actual home — postal code, home type, square footage, number of windows, style, colour, and window series — and shows you a real-time estimate, plus a preview of your own home with your selected exterior colour, before you ever have to enter your name or phone number. Answer the questions above to get your instant estimate or read on to see exactly how the calculator works and what shapes your number.

How the Replacement Windows Calculator Works

The calculator walks through seven quick steps:

Step 1 — Postal code

Confirms you're in a Canadian Choice service area and localizes your estimate.

Step 2 — Home type

Detached, semi-detached, or townhouse.

Step 3 — Square footage

From under 1,500 sq/ft up to 5,000+ sq/ft.

Step 4 — Number of windows

Use the counter to enter exactly how many windows you're pricing. Each individual panel counts as one window. For example, a 3-panel opening counts as 3 windows.

Step 5 — Style

Contemporary or traditional, so the estimate reflects the look you actually want.

Step 6 — Exterior colour

Choose from Canadian Choice's standard exterior colour range (including the most popular finish) or a custom colour, and preview it directly on a street-view photo of your own home.

Step 7 — Window series

draftLOCK™, draftLOCK™ Plus, or TrueCrankless™ - see "Choose Your Window Series" below for what sets each apart.

From there, the calculator returns an estimated monthly payment range and total project range based on your exact selections. For example, a 5-window project in a 1,501–2,000 sq/ft home with Anthracite Grey frames and draftLOCK™ might return an estimate in the $21–$35/month range, or roughly $3,163–$5,376 total. Your own number will depend on your specific selections.

No personal information is required to see your estimate. You'll only be asked for your name, phone number, and email if you choose to request a firm, in-home quote afterward.

What Shapes Your Calculator Estimate

Five inputs drive your number:

Number of windows being replaced
Home size (square footage)
Window series selected (draftLOCK™, draftLOCK™ Plus, or TrueCrankless™)
Exterior colour and finish (standard colours vs. custom)
Whether you add professional installation at the discounted bundled rate offered in your results

Choose Your Window Series

Canadian Choice's standard multi-point locking window series, engineered for day-to-day energy efficiency and security. This is the recommended starting point in the calculator for most homeowners.

An upgraded version of the draftLOCK™ platform for homeowners who want a step up in performance and features beyond the standard series.

TrueCrankless™

Canadian Choice's tilt-and-turn style window, opening up to 180 degrees for ventilation and easy interior cleaning, with multiple locking points across all four sides of the sash for added security.

See It on Your Home Before You Buy

Instead of a generic colour swatch or rendering, the calculator's colour step shows your selected exterior finish applied to an actual street-view photo of your home, so you can see how black, sandalwood, brown, green, navy, white or a custom colour will actually look on your house before you request a quote.

Financing Your Windows

Your estimate includes a monthly payment range in addition to the total project cost, based on financing through VAULTPAY. You can check whether you pre-qualify directly from your results before requesting a full, in-home quote.

Frequently Asked Questions

How accurate is the calculator’s estimate?

The calculator gives a personalized estimate range based on the home details, style, colour, and window series you select. Because every home and installation has unique factors — exact measurements, site conditions, and existing frame condition — your final quote is confirmed after a free in-home or virtual consultation.

Do I have to give my phone number or email to see a price?

No. You can complete all seven steps and see your estimated price range without providing any contact information. Your details are only requested if you choose to submit the form for a full quote afterward.

Can I change my answers after I see an estimate?

Yes. Use the Recalculate option to adjust any of your selections — home type, square footage, window count, style, colour, or series — and your estimate updates immediately.

Does the estimate include installation?

The base estimate reflects your product selections. Professional installation can be added at the discounted bundled rate shown with your results.

What’s the difference between this calculator and the Replacement Windows Cost Guide?

The calculator gives you a personalized estimate for your specific home and selections. The Cost Guide is a reference resource with typical price ranges by window type, size, and province, useful if you’re researching before you’re ready to configure a project.

Why does the calculator ask for my postal code first?

Your postal code confirms you’re within a Canadian Choice service area so the estimate reflects services actually available in your region.

What happens after I get my estimate?

You can request a free, no-obligation quote directly from your results, and a member of the Canadian Choice team will follow up to confirm exact measurements and finalize pricing.
