How Much Does Professional Window Cleaning Cost in Ontario?

Clean windows can completely transform the look of a home. From improving curb appeal to letting in more natural light, professional window cleaning is one of the easiest ways to instantly freshen up your property. One of the most common questions we get at Blondie’s Window Services is:

“How much does professional window cleaning cost?”

The answer depends on several factors, but this guide will give you a realistic idea of pricing, what affects costs, and what to expect when hiring a professional window cleaning company in Ontario.

Average Window Cleaning Prices

For most residential properties in Ontario, professional window cleaning typically falls within these ranges:

Exterior Window Cleaning

$150–$350

This includes cleaning the outside glass, frames, and detailing around the edges of the windows.

Interior + Exterior Window Cleaning

$250–$600+

Interior cleaning requires additional time and detail work, especially on larger homes or homes with many panes.

Larger Homes & Custom Properties

$600–$1,500+

Luxury homes, waterfront properties, and homes with oversized or difficult-to-access windows may require additional labor and specialized equipment.

What Affects Window Cleaning Pricing?

Number of Windows

The more windows and panes a property has, the more time and labor required to complete the job properly.

Accessibility

Second-storey and third-storey windows, skylights, walkouts, and tight-access areas can impact pricing due to ladder work and specialized equipment.

Interior vs Exterior Service

Exterior-only cleaning is typically quicker and more affordable, while interior cleaning involves additional detailing and setup inside the home.

Window Condition

Windows with:

• hard water stains
• calcium buildup
• paint overspray
• excessive dirt or pollen
• post-construction debris

may require restoration work beyond a standard maintenance clean.

Screens & Tracks

Detailed screen cleaning and track detailing can also impact pricing, but they make a major difference in the final appearance of your windows.

Why Professional Window Cleaning Makes a Difference

Many homeowners are surprised at the difference professional equipment and techniques make compared to DIY cleaning.

At Blondie’s Window Services, we use professional-grade:

• purified deionized water systems
• water-fed pole technology
• soft wash methods
• professional squeegee techniques
• detailed frame and edge finishing

Our purified water systems help eliminate mineral deposits and leave behind a spotless, streak-free finish.

How Often Should You Have Your Windows Cleaned?

Most homeowners schedule window cleaning:

• Twice per year for general maintenance
• Quarterly for consistently spotless windows
• Monthly for commercial properties or waterfront homes

Spring and fall are the most popular times for residential window cleaning in Ontario.

Bundling Exterior Services

Many homeowners combine window cleaning with:

• gutter cleaning
• house washing

Bundling services can often save both time and money while giving your property a complete exterior refresh.
