Spring is almost here, and with it comes that unmistakable urge to get your home looking its absolute best.
One of the most obvious places to start? The windows.
You know it’s probably time to schedule a proper cleaning… but how often should you actually be booking that in? Is once or twice a year enough, or are you unknowingly letting grime build up for far too long?
You might be surprised to learn that most homes in the UK need their windows cleaned every 6 to 8 weeks to maintain a consistently well-kept appearance.
Read on to learn why that 6 to 8 week schedule works so well, and how to choose the right cleaning frequency for your specific property.
There’s a reason professional window cleaning companies recommend a structured schedule: it’s all about how dirt builds up on glass over time.
For most properties, the ideal cleaning frequency sits somewhere between 4 and 12 weeks, depending on your circumstances.
Here’s what typically happens:
If left much longer, the build-up becomes heavier and more noticeable, especially on homes with larger glass areas or properties located on busy roads where pollution settles more quickly.
That’s why many homeowners find that every 8 weeks is the sweet spot. It keeps windows looking consistently clean without allowing heavy grime to develop.
However, some homes benefit from more frequent visits (around 4–6 weeks), particularly if they’re on main roads or have a large number of windows. Others in quieter areas may comfortably stretch towards 10–12 weeks.
The key is choosing a schedule that suits your property’s size, location, and budget while keeping ahead of visible build-up.
Spring is the ideal time to establish a regular cleaning routine.
After months of winter weather, your windows have endured rain, wind, and the occasional frost, all of which leave their mark on the glass. A good spring window cleaning gives you a fresh start, removing the accumulated grime and revealing just how much brighter your home can look. This is when you’ll notice the difference most dramatically, as the stronger spring sunlight pours in and instantly highlights just how much light you were missing over winter.
In addition to the windows, most professional cleaners can also take care of your gutters, which, after winter, are often filled with leaves, moss, and debris that block proper drainage. When gutters become blocked, water can quickly overflow and start causing issues around your roofline and walls. Taking care of them alongside your windows is a simple, efficient way to protect your property and keep everything looking its best.
While 8 weeks is the ideal baseline, some properties around South West London benefit from more frequent attention.
For example, if you live on a busy main road in areas like Richmond or Twickenham, traffic pollution can coat your windows more quickly. The constant flow of vehicles kicks up dust and deposits a fine film of exhaust particles that dulls the glass. Properties in these locations often look their best when cleaned every 4 to 6 weeks, particularly ground-floor and street-facing windows.
Proximity to trees is another factor that can influence your cleaning schedule, as overhanging branches regularly shed pollen, tree sap, and fine debris that cling to glass and frames. If you have trees near your home, you might find your windows need more frequent attention, especially in spring and autumn. Similarly, if you have pets or young children, interior windows can show fingerprints and nose prints more quickly, though most homeowners find that focusing on exterior cleaning every 6 to 8 weeks keeps the overall appearance sharp, with occasional interior touch-ups as needed.
Many homeowners approach window cleaning as a reactive task. They wait until the windows look noticeably dirty, then book a one-off clean.
The problem with this approach is that your property spends most of the year looking less than its best. By the time you notice the grime, it’s been building up for weeks or even months, and you’ve missed out on the benefits of consistently clean windows.
A regular schedule keeps you ahead. That means:
A regular window cleaner can also keep an eye on other areas of your property. They’ll often let you know when your gutters are due for a cleaning, so you can deal with it at the right time rather than booking it separately in a rush.
If you’ve been meaning to sort your windows “at some point,” consider this your sign.
A simple, consistent schedule now means brighter rooms, clearer views, and a home that always looks (and feels) well cared for.

In most cases, regular window cleaning actually works out better value than booking one-off visits. Many professional cleaners offer lower rates for customers who stay on a schedule, because it allows them to plan routes efficiently and keep work consistent.
There’s also a practical reason it can cost less over time. When your windows are cleaned regularly, there’s no heavy build-up to battle through. That means each visit is quicker and more straightforward, rather than a bigger job that takes extra time.
Not necessarily. Exterior windows tend to get dirty much faster thanks to weather, dust, and traffic pollution, so they usually need professional cleaning every 6 to 8 weeks to stay looking their best.
Interior windows, on the other hand, don’t face the same exposure. For most homes, a cleaning every 3 to 6 months is more than enough. Many people choose to have them done twice a year, often as part of a bigger spring and autumn refresh.
