You want clean windows. You want to know how much it costs before you call anyone. Fair enough. Here are real numbers from a company that does this every day across the Greater Toronto Area.
Most homes in the GTA pay $175 to $500 for professional window cleaning.
That range depends on how big your home is, how many windows you have, how many stories, and whether you want interior, exterior, or both.
More windows = more time = higher price. But most good companies price by the job, not per pane. This protects you from sticker shock on bigger homes.
Second and third floor windows need ladders and more safety equipment. Expect to pay 15-25% more for a two-story home compared to a bungalow.
Exterior only is the most common request. Adding interior windows means moving furniture, protecting floors, and working inside your home. It adds about 40-60% to the price, but the result is worth it.
If your windows haven't been cleaned in years, the first clean takes longer. Hard water stains, paint splatter, and construction debris all add time. After the first deep clean, maintenance visits are faster and cheaper.
Some companies charge $8-$15 per window pane. Sounds cheap until you realize your home has 40 panes and the bill is $500.
We price by the job. You know the total before we start. No surprises. No hidden fees. The price we quote is the price you pay.
The service itself costs the same rate no matter where you live in the GTA. But home sizes vary significantly by neighbourhood, which affects your total. Here's what to expect:
These ranges are for exterior window cleaning on a typical detached home. Interior + exterior adds 40-60%. Condos and townhouses are usually at the lower end.
A bottle of Windex and some paper towels costs $8. A professional cleaning costs $200+. So why pay?
Safety. Falls from ladders send over 100 Canadians to the hospital every year. Second-floor windows are dangerous without proper equipment and training.
Results. Tap water leaves mineral deposits. Paper towels leave lint. Squeegees in untrained hands leave streaks. Professional-grade purified water and equipment deliver a fundamentally different result.
Time. A professional crew cleans a full home in 1-2 hours. DIY takes an entire weekend — and you still miss spots.
Longevity. Purified water cleaning stays clean 3x longer than DIY because there are zero minerals on the glass to attract dust and dirt.
For most GTA homeowners, twice a year is the sweet spot — once in spring (after winter salt and road grime) and once in fall (before closing up for winter). This keeps your home looking great year-round and prevents mineral buildup from becoming permanent.
Consider quarterly cleaning if your home is near a busy road, under heavy tree coverage, close to construction, or if you have hard water stains on your exterior glass.
Regular maintenance visits are faster and cheaper than a deep clean after years of neglect. Most companies (including us) offer 10-20% off for recurring service plans.
Not all companies include the same things. Before you compare prices, ask what's included. At MANTLE, every job includes:
Toronto's tap water contains calcium, magnesium, and other dissolved minerals. When water dries on glass, those minerals remain as white spots, haze, and streaks. That's why a DIY clean looks great wet but disappointing once it dries.
Purified water cleaning uses a multi-stage reverse osmosis and deionization system to strip every mineral from the water. The result is 0 PPM (parts per million) water that dries perfectly clear. No squeegee marks. No chemical residue. Just pure, invisible glass.
Because there's nothing left on the glass surface after cleaning, dirt and dust have nothing to cling to. Your windows stay noticeably cleaner for weeks longer — up to 3x longer in our experience.
No obligation. No pressure. Just real numbers.
