Ask five window cleaning companies for a quote on the same house and you’ll likely get five different numbers. Understanding window cleaning costs starts with knowing what actually changes the price — pane count, access, screens, and whether you want the inside done too all move the number in ways a flat “per window” rate can’t capture on its own.
We’ve priced this work on thousands of homes across Stafford, Fredericksburg, and the surrounding counties over 25+ years, so we know where homeowners usually get surprised and where the number actually lands once someone’s standing in front of the house.
Quick Answer: Residential window cleaning costs typically range from $4–$8 per pane or $10–$20 per standard double-hung window for exterior-only cleaning, with interior+exterior service adding roughly 40–60% more. Industry pricing guides such as Fixr’s Window Cleaning Cost Guide show that window type, accessibility, and service scope are among the biggest pricing factors. In our experience, a typical single-story Northern Virginia home lands around $150–$300 for a full exterior clean, while two-story Colonials with harder access often run $250–$450 due to ladder or lift time—not extra glass.

What “Per Window” Actually Means on a Quote
“How much per window” sounds like a simple question, but it’s really two different pricing models wearing the same phrase. Some companies quote by the pane — every individual piece of glass counts separately, so a large picture window with six panes costs more than a small single-pane bathroom window. Others quote by the window unit, treating a whole double-hung or sliding window as one billable item regardless of how many panes are in the grid.
Per-pane pricing generally runs $4–$8 a pane. Per-window (unit) pricing runs $10–$20 for a standard double-hung, with larger picture windows, bay windows, and French-style panels priced higher individually because of the extra surface area and time.
This is where the sticker shock usually happens — a homeowner compares one company’s “$5 a window” quote to another’s “$15 a window” quote without realizing they’re not measuring the same unit. Always ask which model a quote is using before comparing two numbers side by side.
Why a Two-Story Colonial Costs More Than the Window Count Suggests
On the two-story Colonials we get called out to across Stafford and Spotsylvania, the quote almost never matches what the homeowner expected going in — not because anyone’s trying to pad the bill, but because access changes the math more than glass count does. A single-story rambler with 20 windows can move faster than a two-story home with 14, because every second-floor window on a Colonial usually means a ladder setup, a water-fed pole, or in some cases a lift, and that setup time gets built into the price per window on the upper level.
Steep rooflines, dormers, and windows tucked over a porch roof or bay window bump add even more time, since standard ladder placement isn’t always safe or possible. If your home has any of these features, expect the upper-floor windows to run noticeably higher per unit than the ground-floor ones on the same quote — that’s normal, not an upsell.

Exterior-Only vs. Interior+Exterior: What You’re Really Paying For
Exterior-only cleaning handles pollen film, road grime, and the hard water spotting that builds up from sprinklers and rain — the stuff that’s visible from the street or the driveway. It’s the right call for most homes on a regular maintenance schedule, especially heading into spring when Virginia’s pollen season coats everything in a yellow-green film within days.
Interior+exterior service increases window cleaning costs by roughly 40–60%, mainly because interior work means moving furniture, working around blinds and curtains, and being careful around finished trim — it’s simply slower, more careful work than an exterior pass with a water-fed pole. It’s worth the upgrade before a home sale, after a renovation with heavy dust, or if the interior hasn’t been touched in a few years and you can see it from both sides of the glass.
A cost-conscious approach that works well for a lot of our clients: exterior cleaning on a regular schedule, with interior added every year or two rather than every visit.
What Actually Affects Window Cleaning Costs on a Northern Virginia Home
What we run into constantly on older homes in Fredericksburg and King George is single-pane or storm windows with individual screens and interior wood trim that’s never been touched — that’s a different job than a newer double-hung vinyl window, even if the pane count on the quote sheet looks the same.
A few specifics that consistently affect window cleaning costs beyond simple window count:
- ✅ Screens: Removing, washing, and rehanging screens adds time per window, especially older aluminum screens that need careful handling.
- ✅ Hard water and mineral staining: Windows near sprinkler lines or with years of untreated hard water spotting need extra scrubbing or a specialty treatment, not just a standard wash.
- ✅ Grid/muntin windows: True divided-light windows with wood grids between panes take longer than a single sheet of glass the same size.
- ✅ First-time cleanings: A window that hasn’t been professionally cleaned in years — common on homes that just changed hands — often costs more the first time, with easier maintenance pricing after that.
Deionized (DI) water is what gets a genuinely streak-free finish without leaving mineral residue behind as it dries. Unger Professional explains that purified water removes dissolved minerals that would otherwise be left behind as spotting, making it especially effective on windows with existing hard water buildup.
When It’s Fine to Do It Yourself — and When It Isn’t
Ground-floor windows on a single-story home are honestly a reasonable DIY project for most homeowners — a squeegee, a bucket, and some patience will get you a clean result without much risk. Where it stops making sense is height. OSHA recommends placing ladders only on stable, level surfaces, since improper ladder setup significantly increases the risk of falls. If you’re working around uneven ground, flower beds, or walkways, hiring a professional is often the safer choice.
If your home is single-story with straightforward access, DIY is a fair option and we won’t tell you otherwise. Once you’re dealing with a second story, a steep roofline, or windows over a porch or bay, the cost of a mistake outweighs what you’d save doing it yourself.
Window cleaning also pairs well with other exterior maintenance if you’re already having work done — a lot of homeowners bundle it with a gutter cleaning visit in spring or fall since the crew is already on-site with a ladder.
Frequently Asked Questions
Is window cleaning priced per pane or per window?
Window cleaning costs are usually calculated one of two ways: per pane, which counts each individual piece of glass, or per window, which treats the whole unit as one line item. Ask which model a quote uses before comparing prices between companies.
How much more does a two-story home cost compared to a single-story home?
Upper-floor windows on a two-story home typically cost more per window than ground-floor ones on the same house, due to ladder or lift setup time — not because the glass itself is harder to clean.
Does the price include screens and window sills?
Not always by default — screen removal/washing and detailed sill cleaning are sometimes priced separately, especially on older homes with more screens per window. Confirm what’s included when you get a quote.
How often should I budget for professional window cleaning?
Most homes in this area do well with an exterior clean once or twice a year — commonly before spring pollen season and again in fall — with interior cleaning added less frequently, such as every year or two.
