If you've been putting off window cleaning, one of the first questions on your mind is probably: how long will this actually take? The answer depends on several factors, from the size of your home to the condition of your windows. In this guide, Cleaner-Kenya breaks down typical cleaning times, what affects them, and how professional cleaners get the job done efficiently.
Average Window Cleaning Times
On average, professional window cleaning takes 1 to 4 hours for a standard home. Here's a quick breakdown:
- Small apartment (4–8 windows): 30 minutes to 1 hour
- Medium home (10–15 windows): 1.5 to 2.5 hours
- Large home (20+ windows): 3 to 4 hours or more
If you're cleaning the windows yourself, expect to take 50–100% longer than a professional, especially if you don't have the right tools or experience.
Factors That Affect Window Cleaning Duration
1. Number and Size of Windows
The most obvious factor. More windows mean more time, and large picture windows or floor-to-ceiling glass take longer than standard-sized panes.
2. Accessibility
Ground-floor windows are quick to reach. Second-story windows, skylights, or windows behind furniture and security grilles require ladders, extension poles, and extra care — adding 2–5 minutes per window or more.
3. Dirt and Grime Build-Up
Windows that haven't been cleaned in months or years will have stubborn grime, hard water stains, dust, and even mold. Heavy build-up may require scraping, soaking, and multiple passes, which significantly extends the job.
4. Interior vs. Exterior Cleaning
Cleaning both sides of your windows roughly doubles the time. Many homeowners choose exterior-only cleaning to save time, since the outside accumulates the most dirt.
5. Screens and Tracks
Removing, washing, and reinstalling window screens adds 5–10 minutes per window. Cleaning tracks and sills adds a few more minutes but leaves a noticeably better finish.
6. Weather Conditions
Direct sunlight causes cleaning solutions to dry too fast, leaving streaks, so cleaners work more carefully on hot days. Windy or rainy conditions can also slow things down.
7. Window Type
Storm windows, tinted glass, stained glass, and double-hung windows that need both sashes cleaned take extra time compared to simple fixed panes.
DIY vs. Professional Window Cleaning
While DIY cleaning may seem cheaper, professionals bring experience, commercial-grade squeegees, purified water systems, and proven techniques that deliver streak-free results faster. A job that takes you an entire afternoon could be completed by a professional team in under two hours — with better, longer-lasting results.
At Cleaner-Kenya, our trained window cleaning teams work efficiently while protecting your window frames, curtains, and interiors from drips and damage.
How Often Should You Clean Your Windows?
For most Kenyan homes, we recommend:
- Every 3–6 months for general maintenance
- Every 2–3 months in dusty areas or near busy roads
- Monthly for homes near construction sites or in high-pollen areas
Regular cleaning keeps each session shorter, since grime never gets the chance to build up.
Tips to Speed Up Window Cleaning
- Declutter window areas — move furniture and curtains before the cleaner arrives.
- Schedule regular cleanings — maintenance cleans are faster than deep cleans.
- Book professional services — pros finish in half the time with better results.
- Clean on a cloudy, mild day — solutions won't dry too quickly.
