Commercial & Residential Window Cleaning Quote Calculator: Per-Pane vs Hourly Pricing (2026)
rel="sponsored") that may earn us a commission at no extra cost to you.
Quoting window cleaning by "number of windows" is the fastest way to lose money on a residential estate or commercial office complex. To a homeowner, a massive three-panel bay window, a 16-lite true divided colonial French door, and a standard bathroom slider are each "one window." If you quote a flat $12 per window over the phone without counting individual glass panes, storm inserts, screen washing, deep sill/track vacuuming, and 2nd/3rd-story ladder or water-fed pole (WFP) setups, your effective hourly yield can plunge from $110/man-hour to under $38/man-hour.
Professional window cleaning estimators use a standardized Per-Pane Unit System cross-checked against a minimum Target Hourly Production Rate ($85 to $135/man-hour). By counting every framed piece of glass as a discrete pane unit—and separating high-margin add-ons like deep screen scrubbing ($3–$6/screen), oxidized frame detailing, and hard-water mineral restoration ($15–$45/pane)—you can deliver instant, accurate tiered proposals (Exterior-Only, Interior + Exterior Package, and Deluxe Track/Screen/Sill Restoration).
Use our interactive Commercial & Residential Window Cleaning Quote Calculator to generate side-by-side per-pane and hourly cross-checked quotes in seconds. Pair this calculator with our General Cleaning Quote Calculator, our Residential House Cleaning Estimate Calculator, our ISSA Production Rate & Time Estimator, and our Square Foot vs. Hourly Quoting Calculator when bundling interior maid services with exterior glass maintenance.
1. The Per-Pane & Hourly Cross-Check Bidding Formulas
Top-performing window cleaning operations calculate every bid using the Pane-Count Formula first, and then verify that the quote beats their Man-Hour Floor:
2. Exterior-Only Quote = (Base_Glass_Price × 0.58) + Screen_Washing + Hard_Water_Pane_Restoration
3. Interior-Only Quote = (Base_Glass_Price × 0.48) + Deep_Track_Sill_Detailing
4. Full Inside + Outside Deluxe Quote = Base_Glass_Price + Screen_Washing + Deep_Track_Sill_Detailing + Hard_Water_Pane_Restoration
5. Estimated Crew Man-Hours = (Standard_Panes ÷ 14 panes/hr) + (French_Squares ÷ 45 sq/hr) + (Storm_Units × 0.25 hr) + (Hard_Water_Panes × 0.20 hr)
6. Hourly Floor Check = max(Full_In_Out_Quote, Estimated_Man_Hours × Target_Hourly_Rate)
• Exterior glass faces hydrophobic road film, artillery fungus, pollen, spider webs, and 2nd/3rd-story ladder or DI water-fed pole setup time, so Exterior-Only is always priced at 55% to 60% of the combined In/Out rate. Interior glass is cleaner but requires boot covers, moving furniture/blinds, and drop-cloth protection over hardwood floors, commanding 45% to 50% when booked standalone.

2. 2026 National Window Cleaning Price List (Per-Pane & Add-On Benchmarks)
Before walking a property or counting windows remotely via Google Street View / Zillow listing photos, train your estimators to classify every opening using this standardized 2026 rate matrix:
| Window / Glass / Add-On Type | How to Count Units | 2026 Exterior Only Rate | 2026 Full Inside + Outside Rate | Avg Production Speed (In + Out) |
|---|---|---|---|---|
| Standard Double-Hung / Slider / Casement Pane | 1 standard double-hung window = 2 panes | $3.25 – $5.00 / pane ($6.50–$10/window) | $5.50 – $8.50 / pane ($11–$17/window) | 12 – 16 panes / man-hour |
| Oversized Picture / Floor-to-Ceiling Transom Pane | Each fixed plate glass section > 15 sq ft = 1.5 to 2 panes | $5.00 – $8.00 / pane | $8.50 – $14.00 / pane | 8 – 11 panes / man-hour |
| Sliding Glass Patio Door (Per Panel) | 2-panel sliding door = 2 door panels | $5.50 – $8.00 / panel ($11–$16/door) | $9.00 – $15.00 / panel ($18–$30/door) | 8 – 10 panels / man-hour |
| True Divided-Light French Panes (Cut-Up Grids) | Count each individual small glass square | $0.85 – $1.40 / small square | $1.50 – $2.50 / small square | 35 – 50 small squares / man-hour |

3. Story Height Multipliers, Water-Fed Poles (DI/RO) & Minimum Trip Charges
Modern pure-water Reverse Osmosis / Deionized (RO/DI) carbon-fiber water-fed pole systems allow a single technician to scrub and spot-free rinse 2nd-, 3rd-, and 4th-story exterior windows from the ground at 000 PPM Total Dissolved Solids (TDS) without setting heavy sectional or extension ladders. However, you should never discount your high-reach per-pane price just because your water-fed pole cleans faster:
- 1-Story Ranch / Ground-Level Commercial (1.00x Multiplier): Fast walk-around access with zero ladder repositioning or pole extension necks.
- 2-Story Standard Residential (1.15x Multiplier): Accounts for 24-foot ladder setups, stabilizer standoffs over gutters, or 27-foot carbon-fiber water-fed pole neck fatigue and pure-water DI resin consumption.
- 3-Story / Walkout Basement / Steep Hillside Grade (1.30x to 1.45x Multiplier): Requires 32-to-40-foot ladders, two-person spotter safety compliance, or high-modulus 40-foot WFP poles plus interior 16-foot A-frame foyer ladders for vaulted chandelier windows.
- Minimum Residential Job Floor ($175 – $250): Never roll a truck for a residential job under $175 (or $45–$65 for a dense commercial storefront route stop) due to windshield travel time, hose unrolling, and setup overhead.
4. Hard-Water Restoration & Post-Construction Glass Scraping Rules
Two specialty window services generate 40%+ net margins when priced as separate line items—and bankrupt unaware contractors when bundled for free:
- Hard-Water Calcium &Silica Stain Restoration ($15 – $45/pane): Lawn irrigation sprinklers spray mineral-heavy groundwater onto lower-story glass, baking calcium carbonate and silica into the microscopic pores of the glass under UV heat. Standard squeegee soap will not touch it. Always perform a Paid Test Pane first and bill $15–$25/pane for Stage-1 acid/0000-steel-wool treatment or $35–$65/pane for Stage-2 rotary cerium oxide polishing.
- Post-Construction Window Cleaning (2.0x to 2.5x Base Rate + Scratch Waiver): Removing painter's overspray, stucco splatter, mortar, and factory sticker adhesive requires 4-inch razor scrapers and triple-pass washing. Because poor-quality heat-treated tempered glass often suffers from fabricating debris (microscopic glass roller nibs fused during tempering that scratch when scraped), always require the builder or homeowner to sign an IWCA Fabricating Debris & Tempered Glass Scratch Waiver before touching a single pane with a razor blade.
5. Worked Window Bidding Scenarios: 2-Story Suburban Home vs. Commercial Medical Plaza
See how the Per-Pane and Hourly Floor equations work together on two real-world 2026 jobs:
Scenario A: 3,200 Sq Ft Two-Story Suburban Residence (26 Double-Hung Windows + Patio Slider)
- Pane & Unit Count: 26 double-hung windows = 52 standard panes; 1 two-panel sliding glass patio door = 2 door panels; 1 front entry sidelight door with 12 small French squares; 26 removable screens; and 4 lower panes etched by lawn sprinklers.
- Base Glass Math ($6.50/pane, $10/door panel, $1.75/French sq, 1.15x 2-Story Multiplier):
[(52 × $6.50) + (2 × $10.00) + (12 × $1.75)] × 1.15 = ($338 + $20 + $21) × 1.15 = $435.85 Base In/Out Glass. - 3-Tier Customer Proposal Outputs:
• Tier 1 (Exterior Glass + Basic Screen Brush):($435.85 × 0.58) + (26 screens × $4.00) = $356.79
• Tier 2 (Full Inside & Outside Glass + Screen Wash):$435.85 + $104.00 = $539.85
• Tier 3 (Deluxe In/Out + Deep Track Detailing @ $3/window + 4 Hard-Water Panes @ $20):$539.85 + $78.00 tracks + $80.00 mineral removal = $697.85(Estimated 5.4 man-hours = $129.23 / man-hour).
Scenario B: Bi-Weekly Commercial Retail & Restaurant Strip Route
- Route Profile: 18 large ground-floor commercial plate glass panes + 2 glass entry doors (4 sides total), cleaned inside and out every 2 weeks.
- Pricing Math: At $3.50/pane inside & out for recurring route glass, raw count is
20 panes × $3.50 = $70.00 per bi-weekly service. With a single route technician completing the storefront in 42 minutes (0.70 man-hours), the job yields $100.00 per man-hour and $1,820/year in predictable contract revenue.
6. Frequently Asked Questions (Window Cleaning Pricing & Bidding)
How much should I charge per window pane vs per window unit in 2026?
In 2026, professional window cleaners price by individual glass pane rather than whole window assemblies to avoid underbidding large double-hung or triple-slider units. The national benchmark for standard residential glass is $4.50 to $8.00 per pane for inside-and-outside cleaning ($9.00 to $16.00 for a standard 2-pane double-hung window). Exterior-only cleaning typically bills at 55% to 60% of the full inside/outside rate, while interior-only cleaning bills at 45% to 50%.
How do you price French windows, storm windows, and screen washing?
True divided-light French panes (small cut-up glass squares) are priced at $1.25 to $2.50 per individual small pane inside and out because each square requires four separate detailing edges. Traditional triple-track aluminum storm windows require disassembly and four glass surfaces per opening, commanding $18.00 to $30.00 per window assembly. Basic screen brushing/rinsing adds $3.00 to $4.00 per screen, while deep tube-washer screen scrubbing adds $5.00 to $8.00 per screen.
What is the target hourly revenue per technician for residential vs route commercial window cleaning?
Residential window cleaning businesses target $85.00 to $135.00 per man-hour using traditional mop-and-squeegee work inside and Deionized (DI) / Reverse Osmosis (RO) carbon-fiber water-fed poles up to 3 stories outside. High-frequency ground-floor commercial storefront route work (weekly or bi-weekly restaurants and retail strips) targets $65.00 to $90.00 per man-hour due to high route density and zero ladder setups.
How much extra should window cleaners charge for hard-water stain removal and post-construction glass scraping?
Never include sprinkler hard-water calcium stain removal or post-construction silicone/stucco scraping in a standard maintenance window cleaning quote. Stage-1 mineral oxidation removal using mild acid paste or 0000 steel wool bills at $15.00 to $25.00 extra per affected pane, while Stage-2 machine polishing with cerium oxide compounds bills at $35.00 to $65.00 per pane. Post-construction window detailing multiplies your base inside/outside rate by 2.0x to 2.5x and requires a signed Tempered Glass Scratch Waiver.
