Window Cleaning Cost Guide 2026: Pricing by Window Count, Story, and Type

What Determines Window Cleaning Cost

Window cleaning pricing is more nuanced than most homeowners expect. Unlike services like lawn mowing or gutter cleaning, where pricing is primarily based on property size, window cleaning costs are influenced by a combination of factors that can vary significantly from one home to the next.

Understanding these factors helps you get accurate quotes, compare providers fairly, and identify opportunities to reduce costs without compromising quality.

Pricing by Home Size and Window Count

The most common pricing structure for residential window cleaning is per-window or per-home based on size. Here is what Okanagan homeowners can expect in 2026.

Per-Window Pricing

Per-Home Pricing by Size

Many window cleaning companies offer flat-rate or range pricing based on home size, which simplifies quoting and is often more economical for the homeowner than strict per-window pricing.

These ranges assume a standard two-storey home with a mix of standard and large windows. Homes with many large windows, significant glass walls, or specialty architectural features will be at the higher end or above these ranges.

Pricing Factors That Increase Cost

Number of Storeys

Height is one of the biggest cost multipliers in window cleaning. Ground-floor windows can be cleaned quickly and safely from the ground. Second-storey windows require ladders, water-fed poles, or boom lifts. Third-storey or higher windows require specialized equipment and safety procedures.

For example, if a ground-floor window costs $8 to clean, the same window on the second storey costs approximately $10 to $12, and on the third storey approximately $12 to $16.

Window Accessibility

Some windows are harder to reach regardless of storey height:

• Windows above garages or extensions where a ladder cannot be safely placed
• Windows behind obstacles like bushes, decks, or fences
• Windows on steep slopes where ground-level access is difficult
• Windows near overhead power lines that require special safety precautions
• Interior windows blocked by furniture that the cleaner must work around

Providers may charge a per-window surcharge of $3 to $10 for difficult-access windows, or they may note these during the quoting process and include the additional cost in the flat rate.

Window Type and Condition

Specialty shapes. Round, arched, triangular, and custom-shaped windows take longer to clean than standard rectangular windows. Expect a 25 to 50 percent surcharge per window.

Divided-light windows. Windows with grids, mullions, or divided panes (common in heritage and traditional-style homes) require each pane to be cleaned individually. A window with 6 or 9 panes takes significantly longer than a single-pane window of the same size.

Hard water stains. In the Okanagan, hard water from sprinkler overspray is a common problem, particularly on windows facing irrigated lawns. Mineral deposits bond to glass and cannot be removed with standard cleaning techniques. Hard water stain removal requires acid-based products and often hand scraping, which adds $5 to $15 per affected window.

Construction residue. New construction or renovation residue (paint overspray, caulking, stucco splatter, adhesive residue) requires careful scraping and solvent treatment. This is a specialized service typically priced at $10 to $25 per window.

Neglected windows. If your windows have not been cleaned in several years, the first cleaning will take significantly longer than a maintenance cleaning. Accumulated grime, oxidation, and staining require more time and product. Expect a 25 to 50 percent premium for the initial cleaning, with subsequent cleanings at standard rates.

Seasonal Pricing Patterns

Window cleaning pricing in the Okanagan does not fluctuate as dramatically as some other services, but there are patterns worth noting:

Spring (April-May): Peak demand as homeowners clean up after winter. Providers are busy, and wait times for scheduling can be 2 to 4 weeks. Pricing is at standard rates.

Summer (June-August): Moderate demand. Good availability. Standard pricing. The warm, dry conditions make this the easiest time for exterior window cleaning.

Fall (September-October): Lower demand. Good availability. Some providers offer 5 to 10 percent discounts for fall bookings. This is actually an excellent time for window cleaning because you get clean windows for winter and can inspect for seal failures before cold weather.

Winter (November-March): Lowest demand. Some providers offer off-season discounts of 10 to 15 percent. However, cold temperatures make exterior cleaning more difficult, and some providers do not offer service below certain temperatures (typically minus 5).

DIY vs. Professional: Cost and Quality Comparison

DIY Window Cleaning Costs

After the initial investment, ongoing costs are minimal - replacement solution and cloths totalling $15 to $30 per year.

Time Investment

For an average 20-window home:

• DIY interior and exterior (ground floor only): 2 to 3 hours
• DIY interior and exterior (with second storey, using extension pole): 3 to 5 hours
• Professional service: 1 to 2 hours (you are free during this time)

When DIY Makes Sense

• Single-storey homes with easy-access windows
• Small homes with fewer than 15 windows
• Homeowners who enjoy the work and have the time
• Between professional cleanings for touch-ups

When Professional Service Makes Sense

• Two-storey or taller homes (ladder safety)
• Homes with many windows or specialty glass
• Homes with hard water staining (requires professional products)
• Windows with difficult access
• When your time has greater value spent elsewhere
• For annual inspection of window seals and frames

How Many Times Per Year Should You Clean?

For most Okanagan homeowners, twice per year provides the best balance of clean windows, reasonable cost, and sufficient inspection frequency to catch seal failures and frame issues early.

What to Look for When Hiring a Window Cleaner

Insurance

Any window cleaning provider working on your property should carry:

• General liability insurance (minimum $2 million)
• WorkSafeBC coverage for their employees
• Vehicle insurance for their service vehicles

Ask for proof of insurance. If an uninsured cleaner falls from a ladder on your property, you may be held liable.

Equipment and Techniques

Professional window cleaners use several methods:

Traditional (squeegee and solution). The industry standard for both interior and exterior cleaning. Produces the best results on most window types.

Water-fed pole systems. Uses purified water pumped through a telescoping pole to clean exterior windows from the ground. Eliminates the need for ladders on buildings up to three storeys. The purified water dries without spots or streaks.

Rope access or boom lift. For tall buildings or windows that cannot be reached by ladder or pole. Significantly more expensive but necessary for some properties.

The best providers use a combination of techniques matched to each window's requirements.

Guarantee

Reputable window cleaners offer a satisfaction guarantee - typically promising to return within a specified period (24 to 72 hours) to address any missed spots or streaks at no additional cost. Ask about the guarantee before booking.
