Window cleaner appointments often get pushed to the bottom of the household to-do list, but clean windows can significantly improve both the appearance and hygiene of your home. Whether you’re maintaining kerb appeal or trying to let more natural light into your living space, knowing when and how often to clean your windows is essential.
Curious when your windows deserve a proper scrub? In this article, we explore the best times of year to consider hiring a professional window cleaner, how often your panes need attention, and whether DIY window cleaning is worth the hassle or just a streaky regret waiting to happen.
Why Clean Windows Matter?
Clean windows do more than make your home look tidy from the outside. They:
- Let in more natural light, which can improve mood and reduce electricity usage.
- Prevent long-term damage caused by the build-up of grime, mould or hard water stains.
- Improve visibility from inside your home.
- Add to the overall impression of a well-maintained property.
Neglecting window cleaning can lead to permanent marks or damage, especially if bird droppings or mineral deposits are left unchecked for months.
Ideal Times of Year to Book a Window Cleaner
In the UK, certain seasons are more suitable for scheduling professional window cleaning. Here’s a breakdown of what to expect throughout the year.
1.Spring
Spring is one of the best times to book a window cleaner. After months of rain, wind and dirt accumulation during the winter, windows often need a deep clean. Tree pollen, dust and insects can also start to appear in spring, which makes regular cleaning important.
Key Benefits:
- Removes winter residue and grime.
- Prepares windows for longer daylight hours.
- Pollen build-up is easier to manage early in the season.
2. Summer
While summer brings fewer weather-related issues, it’s still beneficial to maintain window cleanliness during this season. If you entertain outdoors or have children and pets going in and out, fingerprints and smudges can accumulate quickly.
Key Benefits:
- Keeps windows presentable for guests.
- Maximises natural light during longer days.
- Prevents marks from drying too quickly and causing streaks.
3. Autumn
Autumn is another ideal time to clean your windows, especially before the colder months arrive. Falling leaves, increased rain, and shifting weather conditions can quickly create build-up around window frames and sills.
Key Benefits:
- Prepares your home for the darker months ahead.
- Prevents dirt from becoming ingrained during winter.
- Can help seal out draughts and damp if sills and seals are inspected.
4. Winter
Although not as popular, winter window cleaning is still possible — especially in milder parts of the UK. Rain may keep windows superficially clean, but residue from pollutants or grit can stick. If you’re selling your property or hosting guests over the holidays, a winter clean can make a difference.
Key Benefits:
- Maintains clarity despite grey skies and shorter days.
- Removes residue from salt, grit or air pollution.
- Can be timed to coincide with internal cleaning for better visibility.
How Often Should You Book a Professional Window Cleaner?

There’s no universal answer, as frequency depends on your location, home type, and personal preference. However, these general guidelines can help:
1. Urban Homes: Every 4–6 weeks
City properties tend to accumulate dirt faster due to traffic pollution and construction dust.
2. Suburban Homes: Every 6–8 weeks
Homes in quieter areas may not get dirty as quickly, but can still collect pollen, bird droppings and seasonal debris.
3. Coastal Homes: Every 4 weeks
Salt in the air can cause quicker build-up and even long-term damage to window surfaces if not cleaned regularly.
4. Rural Homes: Every 6–8 weeks
Farm activity, insects, and seasonal mud splashes can require consistent cleaning.
Top Tip: For upper storeys, skylights or conservatories, booking a professional cleaner is usually safer and more efficient than attempting a DIY clean.
Is DIY Window Cleaning Worth the Hassle?
It depends on your time, equipment and access to the windows. Here’s a quick guide.
👍 Pros of DIY Window Cleaning | 👎 Cons of DIY Window Cleaning |
Cost-saving, especially if you only clean ground-floor windows. | Safety risks with ladders or awkward angles. |
Immediate availability — no need to wait for an appointment. | Cleaning multi-storey or large windows can take hours |
Control over products used (ideal for eco-conscious households). | Streaks and smudges are common without Pro Tools. |
DIY may work well for quick spot cleans, internal glass or small bungalows, but for thorough, streak-free results, especially on upper floors, hiring a professional window cleaner is usually the best option.
What to Expect from a Professional Window Cleaner?
Modern window cleaners in the UK often use water-fed pole systems, which allow for safe cleaning of windows up to several storeys high without the need for ladders. This method uses purified water that doesn’t leave residue, which results in a clear, streak-free finish.
A good professional will:
- Arrive on time and respect your property.
- Clean window frames and sills as well as the glass itself.
- Offer interior and exterior cleans, depending on your request.
- Provide a regular schedule or one-off cleans to suit your needs.
If you’re considering regular bookings, look for cleaners with public liability insurance and online reviews for reliability.
Additional Considerations to look for:
- Weather Conditions
Contrary to popular belief, professional window cleaning can still be done on cloudy days or drizzle. However, in heavy rain, strong winds or sub-zero temperatures, it’s better to postpone. - Access Requirements
Inform your window cleaner in advance if certain windows are locked or obstructed. Ground conditions like gravel or uneven paving may affect access for equipment. - Eco-Friendly Options
Many cleaners now offer chemical-free or biodegradable cleaning solutions. If this is important to you, be sure to ask in advance. - Cost
On average, window cleaning in the UK ranges approximately from £10–£40, depending on the number of windows, height, and location. Monthly contracts may offer discounts.
Takeaway!
Window cleaner services play an important role in home maintenance, yet they’re often overlooked. Booking a cleaner at the right times throughout the year can help you maintain the value, appearance and energy efficiency of your home.
Whether you opt for a one-off seasonal clean or set up a regular schedule, knowing when and how to act makes all the difference. DIY might be suitable for smaller properties or quick touch-ups, but for reliable, long-lasting results, hiring a professional is usually worth the investment.
