Window Cleaning Cost: Residential & Commercial Pricing
Clean windows transform a home. They let in more natural light, make rooms feel larger, and dramatically improve curb appeal. In Oregon, where overcast skies are the norm for most of the year, maximizing the light that does come through is especially important.
But window cleaning is one of those services where pricing feels opaque. Is it per window? Per pane? Per hour? This guide breaks down exactly what you should expect to pay for residential and commercial window cleaning in Oregon.
Residential Window Cleaning Costs
Per-Pane Pricing
The most common residential pricing model is per pane (each individual piece of glass):
| Window Type | Per Pane (interior + exterior) |
|---|---|
| Standard single-pane | $4 - $8 |
| Double-hung (2 panes) | $8 - $16 |
| Large picture window | $10 - $25 |
| French doors (per door) | $8 - $15 |
| Skylights | $15 - $30 each |
| Storm windows (additional) | $2 - $5 per pane |
By Home Size
| Home Size | Window Count (typical) | Cost Range |
|---|---|---|
| Apartment / Condo | 8 - 15 panes | $50 - $120 |
| Small home (2 BR) | 15 - 25 panes | $100 - $200 |
| Medium home (3 BR) | 25 - 40 panes | $175 - $325 |
| Large home (4+ BR) | 40 - 60 panes | $275 - $500 |
| Estate / Custom | 60+ panes | $400 - $800+ |
Interior vs. Exterior
| Service | Cost Multiplier |
|---|---|
| Exterior only | 0.6x full price |
| Interior only | 0.5x full price |
| Both interior + exterior | 1.0x (full price) |
Most homeowners opt for both interior and exterior cleaning, which provides the complete transformation. Interior-only is common for condos and apartments where exterior access is limited.
Note: Window cleaning represents a growing service category that Otesse is evaluating as part of our exterior home services expansion in Oregon.
Factors That Affect Window Cleaning Cost
Number of stories. Second-floor windows require ladders or water-fed poles, adding time and equipment cost. Third-floor and above requires specialized equipment.
| Floor | Cost Impact |
|---|---|
| Ground floor | Baseline |
| Second floor | +25-50% |
| Third floor+ | +50-100% |
Window condition. Windows that have not been cleaned in years, have hard water stains, or have construction debris require additional time and treatment.
| Condition | Impact |
|---|---|
| Regularly maintained | Standard pricing |
| 1-2 years since cleaning | +10-20% |
| 3+ years / heavy buildup | +25-50% |
| Hard water stains (mineral deposits) | +$5-15 per affected pane |
Window accessibility. Windows blocked by landscaping, furniture, or security bars require extra time to access.
Screen cleaning. Most companies include basic screen cleaning or offer it as a low-cost add-on ($1 to $3 per screen). Heavily soiled screens may cost more.
Track and sill cleaning. A thorough window cleaning should include tracks and sills. Some companies include this; others charge $2 to $5 per window.
Commercial Window Cleaning Costs
Commercial pricing is typically structured differently from residential:
| Property Type | Pricing Model | Cost Range |
|---|---|---|
| Storefront (ground level) | Per pane or per visit | $50 - $200/visit |
| Office building (1-3 stories) | Per pane | $3 - $8/pane |
| Multi-story commercial | Per square foot of glass | $0.50 - $2.00/sq ft |
| Restaurant | Per pane + interior surfaces | $75 - $250/visit |
| Retail store | Per visit (contract rate) | $100 - $400/visit |
Contract rates: Commercial properties that schedule regular cleaning (weekly, biweekly, or monthly) receive 15% to 30% lower per-visit rates compared to one-time bookings.

When to Clean Your Windows in Oregon
| Season | Recommendation | Notes |
|---|---|---|
| Spring (March-April) | Essential | Remove winter rain deposits, pollen |
| Summer (June-July) | Ideal | Dry weather, longest drying time, best results |
| Fall (September-October) | Recommended | Before rainy season seals windows shut |
| Winter (November-February) | Not recommended | Rain negates cleaning within days |
Oregon-specific timing: The best windows cleaning results in Oregon come from scheduling in late spring (May) or early fall (September). These months offer reasonable weather while avoiding peak summer pricing and winter rain.
Frequency recommendation:
- Residential: 2 times per year (spring and fall)
- Storefront: Weekly to monthly (depending on foot traffic and rain exposure)
- Office: Quarterly
Window Cleaning Methods
| Method | Description | Best For | Cost |
|---|---|---|---|
| Traditional squeegee | Hand cleaning with squeegee and solution | Interior + accessible exterior | Standard pricing |
| Water-fed pole | Purified water + telescoping brush poles | Upper-story exterior (no ladder) | Slightly higher |
| Rope access / aerial | Technicians suspended from roof | High-rise commercial | Premium pricing |
| DIY spray + wipe | Spray cleaner + paper towels or cloth | Not recommended for quality results | Lowest cost, lowest quality |
Professional water-fed pole systems use deionized water that dries streak-free without squeegeeing. This method is increasingly common in Oregon because it is safer (no ladders) and works well in our climate.
The Value of Clean Windows
Home value. Clean windows increase perceived home value and are a key element in real estate staging and photography. See our pre-sale cleaning guides for more.
Energy efficiency. Clean windows transmit up to 20% more natural light, reducing the need for artificial lighting during Oregon's short winter days.
Window longevity. Regular cleaning removes corrosive contaminants (minerals, acid rain residue, moss spores) that etch glass over time. Neglected windows may require restoration or replacement sooner.
Mood and productivity. Studies show that natural light improves mood, sleep quality, and workplace productivity. In Oregon's gray climate, every photon counts.
