How Long Does Window Cleaning Take for a House? A Homeowner’s Guide to Time, Tools, and Realistic Expectations

Window cleaning isn’t just about making glass sparkle—it’s about restoring natural light, improving curb appeal, and making your home feel fresh and cared for!

One of the first questions homeowners ask before scheduling a cleaning is:

“How long will it take to clean all my windows?”

It’s a fair question—and while the answer depends on several variables, there are practical ways to set realistic expectations. This guide breaks down the real-world factors that affect window cleaning time, including insights for both DIYers and those considering professional help.

Why the Time Varies So Much from House to House

“No two houses are the same,” one residential crew member from Evergreen Maintenance, explains. “It’s not just about square footage—it’s about how the windows are designed, how high they are, how accessible they are, and what kind of shape they’re in.”

Some homeowners are surprised to learn that a small house with tricky, multi-pane windows can take longer to clean than a large home with wide, modern glass panels. That’s why a professional cleaning company typically asks for photos or performs a walkthrough before confirming a quote or timeline.

If you’re hiring a service, make sure they also ask questions about access, window design, and screen removal. These aren’t small details—they’re time-critical considerations.

6 Key Factors That Affect Residential Window Cleaning Time

1. Number of Windows (and Panes)

The more windows you have, the longer the job takes—but pane count plays an even bigger role. Double-hung windows, storm windows, or French panes significantly increase cleaning time compared to single-panel glass.

2. Height of the House

Cleaning a single-story home is fairly straightforward. Add a second or third story, and you’re dealing with ladders, extension poles, or specialized safety gear.

3. Window Condition

Older or neglected windows often have baked-on grime, mineral stains, insect debris, or paint overspray. These conditions require deep cleaning methods and can add 30–50% more time to a standard job.

According to Family Handyman, even basic buildup can take extra effort if you’re not using the right technique or tools.

4. Screens and Tracks

Cleaning isn’t just about the glass—tracks, frames, and screens need attention too. Removing and washing screens, scrubbing debris from sills, or vacuuming dirt from tracks can easily add 10–20 minutes per window.

5. Interior vs. Exterior

Exterior-only cleaning is faster, but many homeowners also want interior glass cleaned, especially in kitchens, sunrooms, or areas with condensation marks. Interior work means moving furniture, protecting floors, and often working around tight spaces.

6. DIY vs. Professional Crew

If you’re doing it yourself, expect to spend most of a weekend tackling windows. A professional team, equipped with extension poles, squeegees, and purified water-fed systems, can do the same job in a few hours—and often more safely.

For homeowners wondering whether it’s worth outsourcing, companies like Evergreen Maintenance offer helpful insights on what to expect when hiring professional cleaners and how it saves both time and effort. While the article is written for commercial spaces, many of the same principles apply: outsourcing leads to higher-quality results, consistent maintenance, and fewer distractions from your personal schedule.

Realistic Time Estimates by Home Type

Here’s a general guide for how long you can expect window cleaning to take, depending on the size and layout of your home:

Home TypeExterior-OnlyInterior + Exterior
Condo / Apartment (up to 10 windows)30–60 minutes1.5–2 hours
Small Home (1 story, 15–20 windows)1.5–2 hours2.5–3.5 hours
Medium Home (2 stories, 25–35 windows)2.5–3.5 hours4–5.5 hours
Large Home (3+ stories, 40+ windows)4–6 hours6–8+ hours

Note: Deep cleans, storm windows, or post-renovation conditions may require additional time.

Common Causes of Delay

Even if a job seems simple at first glance, a few overlooked details can drag out the timeline:

  • Furniture or decor blocking windows inside
  • Difficult-to-remove screens or storm panels
  • Unusually dirty or stained glass
  • Weather delays (especially wind or rain)
  • Skylights, sliding glass doors, or sunroof panels

How to Make It Go Faster

Whether you’re hiring a crew or doing it yourself, here are a few ways to keep things moving:

  • Clear sills and furniture from windows ahead of time
  • Remove screens if you’re comfortable doing so
  • Book cleaning during dry, mild weather
  • Schedule routine maintenance to avoid grime buildup
  • Use the right tools— Better Homes & Gardens recommends microfiber cloths, squeegees, and vinegar-based cleaners for speed and clarity

Final Thoughts: It’s Worth the Time

Clean windows bring more than just visual clarity—they make your home feel lighter, more open, and more inviting. Whether you’re prepping for a party, listing your home, or just want to enjoy the view, clean glass makes a subtle but powerful difference.

“People don’t realize how much cleaner their home looks and feels until the windows are done. It changes the entire atmosphere.” – says Jon Kaycee, a happy customer with really clean windows.

If you’re planning a DIY project or hiring a service, use this guide to estimate the time involved, plan around your schedule, and ensure the job is done right—with no surprises.
