One of the most common questions we get asked is: "How often should I have my windows cleaned?" The short answer is every four weeks — but the real answer depends on your property and surroundings.
Why Every Four Weeks Works Best
A four-weekly cleaning cycle is the sweet spot for most homes. It keeps your windows looking consistently clean without over-servicing. After about four weeks, airborne dust, pollen, and moisture start to build up noticeably — especially on south-facing glass that catches the most weather.
Regular cleaning also means each visit is quicker and more effective. When windows are maintained on a schedule, dirt doesn't get the chance to bond with the glass, so the results are better every time.
Factors That Affect Cleaning Frequency
Trees and Foliage
Properties surrounded by trees — particularly deciduous ones — tend to accumulate sap, pollen, and leaf debris faster. If you've got overhanging branches, you may benefit from a three-weekly cycle during spring and summer.
Road Proximity
Homes on busy roads or near junctions pick up more traffic film and brake dust. This grey film builds up gradually and can etch into glass over time if left unchecked.
Coastal or Exposed Locations
Salt spray and wind-driven grit are harsh on glass. Properties in exposed positions — hilltops, coastal areas, or open countryside — often need more frequent attention.
Somerset-Specific Factors
Here in Somerset, we deal with a few unique challenges. Agricultural dust from farming activity is common across the Levels and surrounding areas, particularly during harvest season. The high moisture levels on the Somerset Levels also encourage algae and green growth on frames and sills, which regular cleaning keeps in check.
Signs Your Windows Need Cleaning
- Visible watermarks or streaks after rain
- A hazy or dull appearance when light hits the glass
- Green algae forming on frames or sills
- Cobwebs in window corners (especially ground-floor windows)
- You can't remember the last time they were done
How Regular Cleaning Prevents Long-Term Damage
Dirty windows aren't just an eyesore — they can actually degrade over time. Hard water deposits, mineral buildup, and acidic contaminants (like bird droppings or tree sap) can etch into glass permanently if left for months. Regular cleaning removes these before they cause lasting damage, protecting your investment and keeping your property looking its best.
The same applies to uPVC frames and sills. Left uncleaned, they yellow and stain. A regular wipe-down during each window clean keeps them white and extends their lifespan significantly.
Our Recommendation
For most homes in Somerset, a four-weekly clean is ideal. If your property is surrounded by trees, near a busy road, or in an exposed location, consider moving to a three-weekly cycle. We'll always give you honest advice based on your property — no upselling, just what actually makes sense.
