Commercial window washing costs $2 to $15 per pane depending on building height and accessibility. Here is the complete pricing guide.
Commercial window washing costs $2-$8 per pane for standard low-rise windows and $5-$15 per pane for high-rise or specialty windows. For an entire building, expect $200-$1,000 per cleaning for a typical 10,000 sq ft low-rise building and $1,000-$5,000+ for high-rise buildings. Interior cleaning is typically less expensive than exterior, and regular scheduled service costs less than one-time cleanings.
The wide price range reflects differences in building height, access methods, window condition, and frequency. Understanding these variables helps property managers budget accurately and compare quotes from different vendors on an apples-to-apples basis.
Pricing by Building Height and Access Method
Low-rise buildings (1-3 stories): $2-$5 per pane. Accessible from ground level using ladders, water-fed poles, or extension tools. Lowest cost because equipment and labor requirements are minimal. A standard 10,000 sq ft low-rise office with approximately 200 windows costs $400-$1,000 per cleaning.
Mid-rise buildings (4-7 stories): $4-$8 per pane. Requires scaffolding, boom lifts, or rope access depending on building design. Higher equipment costs and safety requirements increase pricing. A mid-rise with 300 windows costs $1,200-$2,400 per cleaning.
High-rise buildings (8+ stories): $8-$15 per pane. Requires specialized rope access techniques, suspended scaffolding, or building-mounted davit systems. Rigorous safety protocols increase costs. A high-rise with 500 windows may cost $4,000-$7,500 per cleaning.
Interior vs. Exterior Window Cleaning Pricing
Interior window cleaning: $2-$5 per pane. Less expensive because it does not require specialized access equipment. However, interior work must be done around building occupants and may require moving furniture. A standard 4-person crew cleans 200-300 interior panes per day.
Exterior window cleaning: $3-$8 per pane for low-rise; $5-$15 per pane for high-rise. Higher costs due to access equipment, weather limitations, and safety requirements. Exterior cleaning also deals with harder-to-remove buildup like hard water spots and pollution residue.
Combined service: Most vendors offer a package price for cleaning both sides at the same visit with a 10-20% discount over separate pricing. See our commercial window washing page for details.
Factors That Affect Window Cleaning Cost
Window condition: Windows with hard water deposits, construction film, or years of grime need additional labor and specialized solutions. Heavy cleaning adds $1-$3 per pane. First-time cleanings for neglected windows cost more than regular maintenance.
Window type and size: Standard office windows (2-4 sq ft) are the baseline. Larger panes, custom shapes, and skylights cost 1.5-2x standard rates. Specialty glass requires specific methods.
Frequency: One-time cleanings cost 20-40% more than scheduled recurring service. Quarterly averages $3-$6/pane vs. $4-$8 for one-time. Monthly drops to $2-$5/pane.
Season: Spring and fall are peak seasons. Winter (above freezing) may have discounts. Interior cleaning is unaffected by weather.
Minimum Charges and Travel Fees
Most window cleaning companies have minimum charges of $150-$350 per visit to cover mobilization. For buildings with fewer than 20-30 windows, expect to pay the minimum rather than per-pane pricing.
Travel fees of $50-$150 may apply for buildings outside the vendor’s service area. Buildings with difficult parking, no freight elevator, or restricted access may incur additional charges. Always ask about minimums, travel fees, and surcharges when getting quotes.
Annual Window Cleaning Budget Guidelines
Low-rise office (200 windows, 2 stories): Quarterly interior/exterior at $4/pane = $3,200/year. Monthly ground floor exterior = $1,200/year. Total: $4,400/year.
Retail storefront (30 windows): Monthly interior/exterior at $3/pane = $1,080/year. Weekly front wipe-down may be included in janitorial contract.
Mid-rise office (300 windows, 5 stories): Quarterly interior at $4/pane = $4,800/year. Semi-annual exterior at $6/pane = $3,600/year. Total: $8,400/year.
High-rise office (500 windows, 12 stories): Semi-annual exterior at $10/pane = $10,000/year. Quarterly interior at $4/pane = $8,000/year. Total: $18,000/year.
How to Save on Commercial Window Washing
Bundle with janitorial contract: Adding window washing to a nightly janitorial contract often reduces pricing by 15-25% because the vendor already has staff and familiarity with the building.
Sign a recurring schedule: Quarterly or monthly service costs significantly less per visit than one-time cleanings. Annual contracts also provide budget predictability.
Schedule interior and exterior together: Having both sides cleaned on the same visit reduces mobilization costs. Many vendors offer a package discount.
Group buildings together: If you manage multiple buildings, have them cleaned on the same day to share mobilization costs across properties.

Final Thoughts
Commercial window washing is a relatively low-cost service with a high impact on building appearance and tenant satisfaction. Clean windows improve natural light, enhance curb appeal, and signal a well-maintained property. Regular scheduled service at competitive per-pane pricing is the most cost-effective approach for most commercial buildings.
