Window cleaning quotes in Herndon range from surprisingly affordable to unexpectedly high — depending on who you hire, what you need, and whether your windows have been cleaned in the last six months or the last six years. This guide breaks down what residential and commercial window cleaning actually costs in Herndon, VA in 2026, across every pricing model the local market uses.
Residential Window Cleaning Prices in Herndon
Most companies in Northern Virginia price residential jobs per pane — that’s the glass surface itself, not the full window frame. A standard double-hung window has two panes.
| Pricing Model | Estimated Rate | Notes |
| Per pane (exterior only) | $4 – $8 per pane | Ground floor standard |
| Per pane (both sides) | $8.70 – $12 per pane | Interior + exterior |
| Whole home flat rate | $150 – $400 | Most common for full-house jobs |
| Per hour | $45 – $75 per cleaner | Extreme soiling or restoration work |
| Minimum visit charge | $100 – $150 | Always applies regardless of window count |
The minimum charge is the figure most homeowners miss when comparing quotes. If your Herndon townhouse only needs four or five windows cleaned, the minimum will be the controlling cost — not the per-pane rate.
Residential Prices by Home Type
| Home Type | Estimated Windows | Estimated Total |
| Single-story home (1 floor) | Up to 10 windows | $120 – $200 |
| Townhouse / 2-story home | 15 – 25 windows | $200 – $375 |
| Large home (2–3 floors, 25+ windows) | 25+ windows | $375 – $550+ |
For Herndon’s typical three-level townhouses, factor in the height surcharge — windows on the third floor add $3 to $5 per pane above the ground-floor rate due to ladder access and safety requirements.
Residential Add-On Prices
The base quote covers glass only. These are always extra.
| Add-On | Estimated Cost |
| Screen cleaning | $3 – $8 per screen |
| Track and sill cleaning | $3 – $8 per window |
| Skylight / rooflight | $12 – $30 per unit |
| Sliding glass door | $10 – $25 per door |
| Storm window (4 glass faces) | +$5 – $12 per panel |
| Hard water mineral removal | +$2 – $10 per window (acid treatment required) |
Hard water staining deserves a specific mention for Herndon. Fairfax County’s water supply has high mineral content — the same issue that affects bathroom tile and shower glass also affects exterior windows hit by irrigation sprinklers. If your exterior glass has white mineral deposits, tell the company upfront. Removing them requires specialized acid-based products and adds time and cost to the job. Standard window cleaning won’t dissolve them. For context on how hard water affects other cleaning costs in this area, see our guide on deep cleaning house cost Herndon VA.
Commercial Window Cleaning Prices in Herndon
Commercial pricing in Herndon depends heavily on building type, height, and contract frequency. The Dulles corridor concentrates storefronts, office parks, and mid-rise buildings within a small area — each priced differently.
| Building Type | Pricing Model | Estimated Cost |
| Street-level storefront | Flat rate per visit | $40 – $75 per visit |
| Low-rise office (1–4 floors) | Per pane | $7 – $15 per pane |
| Mid-rise building (5–10 floors) | Per project | $300 – $800+ |
| High-rise (10+ floors, rappel required) | Per project | $714 – $2,877+ |
| Per sq ft of glass (large facades) | Per sq ft | $0.50 – $1.50/sq ft |
| Hourly (complex access or irregular facades) | Per hour | $50 – $100/hr — up to $170/hr for rappel |
Storefronts along Route 7 and Route 28 in Herndon typically run on weekly or biweekly contracts — the high frequency brings the per-visit rate down significantly compared to a one-time job.

Factors That Affect Both Residential and Commercial Prices
Height and Accessibility
Every floor above ground level adds cost — and risk. Ground-floor windows are the baseline. Second and third floors require extension ladders or water-fed poles. Above four floors, the pricing model shifts entirely.
| Access Level | Equipment | Estimated Surcharge |
| Ground floor | Standard tools | Base rate |
| 2nd floor | Extension ladders | +$1 – $3 per pane |
| 3rd floor | Long ladders / water-fed poles | +$3 – $5 per pane |
| 4th floor+ (commercial) | Boom lifts / cradles | Quoted separately |
| High-rise (rappel) | Certified systems | $714 – $2,877+ per project |
Service Frequency
First-time or annual cleanings cost more than recurring service. A home or business that gets cleaned twice a year accumulates less grime per cycle — the job is faster and cheaper per visit.
| Frequency | Estimated Price Impact |
| First clean / annual only | Full rate + potential first-visit surcharge of 15% – 30% |
| Twice per year (residential standard) | Base rate applies |
| Monthly or quarterly (commercial contracts) | 20% – 40% discount vs. one-time pricing |
Factors Specific to Residential Window Cleaning in Herndon
Window Type and Design
| Window Type | Estimated Impact |
| Standard single pane | Base rate |
| French panes / grid pattern | +$2 – $5 per window — more edge work |
| Bay or bow windows | +$10 – $20 per unit |
| Skylights | $12 – $30 per unit |
| Storm windows (older Herndon homes) | +$5 – $12 per panel — disassembly required |
Storm windows are common in older homes throughout Herndon’s established neighborhoods. Cleaning them properly means removing each panel, cleaning four glass surfaces, and reinstalling — roughly double the time of a standard window.
Northern Virginia’s Pollen Season
Spring pollen in Herndon is among the worst in the Mid-Atlantic. A full window cleaning in March or April will be visibly coated again within a week as oak and tree pollen peaks through May. Most experienced local companies recommend scheduling residential window cleaning in late May to early June — after peak pollen — or in September/October after summer humidity drops. Cleaning at the wrong time of year doesn’t damage anything, but it wastes the investment.
Factors Specific to Commercial Window Cleaning in Herndon
After-Hours and Weekend Surcharges
Most commercial window cleaning in Herndon happens outside business hours to avoid disrupting customers and employees. Standard nighttime rates are typically built into contract pricing. Emergency or unscheduled weekend work carries a surcharge.
| Schedule | Estimated Impact |
| Standard after-hours (built into contract) | Base rate |
| Emergency weekend call-out | +20% – 35% |
Post-Construction Residue
Office build-outs and retail fit-outs near Dulles frequently leave paint overspray, adhesive, and silicone residue on commercial glass. Removing these requires chemical treatment and manual scraping — and approximately doubles the standard per-pane rate to $12 – $20 per pane.
Safety Certifications and Permits
For buildings above four stories in Herndon, cleaning companies must carry commercial liability insurance of $2M to $5M, Workers’ Compensation, and OSHA certification for work at height. If the job requires a boom lift or partial sidewalk closure, municipal permits add further cost. These are not negotiable — they’re legal requirements that reputable companies already have in place.
What to Check Before You Book
Get the quote itemized. Ask the company to list: glass cleaning (interior/exterior), screens, tracks, skylights, and any height surcharges separately. A single-number quote tells you nothing useful when comparing providers.
Ask about the rain guarantee. Local companies like Mason’s Window Cleaning in Herndon offer a 72-hour streak-free guarantee — if rain dirties the glass within that window, they return at no charge. Not every company offers this. Ask before booking.
Confirm insurance. A Certificate of Insurance showing active General Liability (minimum $1M for residential, $2M+ for commercial) and Workers’ Compensation protects you if something breaks or someone is injured on your property.
Time the booking right. For residential jobs, avoid the peak pollen window (late March to mid-May). For commercial, book recurring contracts at least two to three weeks ahead — the Dulles corridor is one of the busier window cleaning markets in Northern Virginia and availability fills up.

Frequently Asked Questions
How much does window cleaning cost per window in Herndon, VA? For a standard residential window cleaned on both sides, the rate in Herndon runs $8.70 to $12 per pane. Exterior-only cleaning runs $4 to $8 per pane. Most companies apply a minimum visit charge of $100 to $150 — so small jobs with fewer than 8 to 10 windows are typically priced at the minimum, not at the per-pane rate.
What is the average cost to clean all windows in a Herndon home? For a standard two-story home or townhouse with 15 to 25 windows, expect to pay $200 to $375 for a full interior and exterior clean. Single-story homes run $120 to $200. Larger homes with 25+ windows run $375 to $550+ before add-ons like screen cleaning, track cleaning, or height surcharges.
When is the best time to schedule window cleaning in Herndon? Late May to early June — after Northern Virginia’s peak pollen season — gives the longest-lasting results. September and October are also good timing as summer humidity clears. Avoid scheduling during peak pollen weeks (mid-April through May) if you want the clean to last more than a few days.
Are screens and tracks included in the window cleaning price? Almost never in the base rate. Screen cleaning typically adds $3 to $8 per screen and track cleaning adds $3 to $8 per window. Always ask for a written quote that separates glass-only pricing from the full package so you know exactly what you’re getting.
Do commercial window cleaning companies in Herndon offer recurring contracts? Yes — and recurring contracts reduce the per-visit cost significantly. Storefronts on weekly or biweekly contracts typically pay $40 to $75 per visit, compared to much higher rates for one-time jobs. Monthly or quarterly commercial contracts can run 20% to 40% less per visit than single-service pricing.
