How Often Should You Get Your Windows Cleaned?

The quick answer: Most UK homes are cleaned on a 4-, 6- or 8-weekly cycle, and six-weekly suits the majority. Homes near busy roads, under trees or in damp, north-facing spots do better at 4-weekly; quieter, sheltered houses can stretch to 8-weekly. More frequent cleans keep the glass looking its best and cost less per visit because there is less build-up to shift.

This guide explains why frequency matters, gives a side-by-side comparison of the common cycles, and walks through the things that actually shift your interval — from roadside dust to north-facing algae. We finish with a Surrey-specific note and a simple way to get a price. If you want the full method and pricing detail, see our window cleaning service page.

Why Frequency Matters More Than You Think

Window cleaning is one of the few jobs where doing it more often is actually cheaper per visit. The reason is simple: dirt, pollen and rain spotting are far quicker to remove when they have only had a few weeks to settle. Leave glass for months and the grime bakes on, frames pick up green algae, and what should be a quick wash becomes a slow restoration job.

That is why a maintained window costs less to clean than a neglected one. On a regular round, every visit is a light touch-up. The hard work was done once, at the first clean, and never has to be repeated. Skip the round for half a year and you are effectively paying for a first clean all over again.

First clean vs maintained glass

The single biggest price difference in window cleaning is between a one-off and a maintained pane. A first or one-off clean tackles built-up dirt and usually costs 50-100% more than a regular visit (Checkatrade 2026; MyJobQuote 2026). Once your windows are on a cycle, the build-up never returns, so each clean after that is faster and cheaper. Choosing a frequency is really about deciding how clean you want the glass to stay between visits.

4-Weekly vs 6-Weekly vs 8-Weekly vs One-Off

Here is how the common cycles compare. The cost notes are relative to each other for the same property, not exact prices — your real figure depends on house size and number of windows. For Surrey price bands, see our window cleaning prices in Surrey guide.

What Drives Your Window-Cleaning Interval

No two houses grime up at the same rate. These are the factors that push you toward a shorter or longer cycle.

1. Roadside dust and traffic film

Homes fronting a busy road pick up a fine, sticky film of brake dust and exhaust grime far faster than houses on a quiet close. If you live on a main route through Redhill or Reigate, a 4-weekly cycle keeps the glass from going hazy.

2. Pollen (spring)

From March to June, tree and grass pollen coats glass with a yellow-green dust that smears if it gets wet. Spring is the season most homeowners notice their windows looking tired, and it is worth tightening the interval over those months even if you relax it in winter.

3. North-facing and shaded glass

North-facing windows and anything under trees stay damp longer, which encourages green algae on the frames and a filmy build-up on the glass. These elevations almost always need cleaning more often than a sunny, south-facing front.

4. Conservatories and skylights

Conservatory glass and roof panels collect leaves, sap and bird mess and are easy to forget. They benefit from being added to the same visit so they are not left months behind the rest of the house. We can reach upper-floor and conservatory glass safely from the ground.

5. Render runoff and overflowing gutters

If rainwater runs off render or a blocked gutter and streaks down your windows, you will see spotting return quickly no matter how often the glass is cleaned. Clearing the gutters fixes the cause — see our gutter cleaning guide for when that is the real culprit.

A Surrey Note: Why Local Conditions Shift the Cycle

Where you are in Surrey genuinely changes how often your windows need attention:

• Horley and the Gatwick area: flight-path grime and busy commercial frontages mean forecourts and roadside homes around Horley grime up faster — lean toward 4-weekly.
• Dorking and Mole Valley: heavy tree cover and a damper microclimate around Dorking drive more algae on frames, so a tighter cadence keeps things in check.
• Busy A23/A25 frontages: homes on the main routes through Redhill and Reigate pick up more traffic film than houses tucked away off the main roads.
• Banstead and the North Downs: quieter, more sheltered streets can often comfortably hold an 8-weekly cycle.

How a Regular Round Actually Works

If you decide to go on a cycle, here is what to expect from us — no surprises, no sales pressure:

• We text before we come so you always know when to expect us.
• No tie-in. You can pause or stop any time; it is meant to be easy to start and easy to leave.
• Frames, sills and doors cleaned every visit at no extra charge — the pure-water pole reaches them as it cleans the glass.
• You do not need to be home. As long as side gates are unlocked, we clean while you are out and let you know we have been.
• Pay after each visit by bank transfer or card — whatever is simplest for you.

We clean with 100% purified water and a water-fed pole, so the glass dries spotless with no chemicals and no ladders leaning on your gutters or flowerbeds. If you have ever wondered why glass dries with white spots, our guide on why windows look spotty after cleaning explains the science.

Frequently Asked Questions

How often should you have your windows cleaned?

Most UK homes are cleaned on a 4-, 6- or 8-weekly cycle. Six-weekly suits the majority of houses. Homes near busy roads, under trees or in damp, north-facing spots benefit from 4-weekly; quieter, sheltered houses can stretch to 8-weekly. More frequent visits keep glass looking its best and cost less per visit because there is less build-up to remove.

Is 4-weekly window cleaning worth it over 8-weekly?

Yes, if your windows visibly grime up between visits. A 4-weekly clean is quicker each time because dirt has not had a chance to bake on, so the per-visit price is usually a few pounds lower than an 8-weekly clean of the same house. Roadside, north-facing or tree-shaded homes especially benefit from the shorter cycle.

Why does a first window clean cost more than later ones?

A first or one-off clean tackles months or years of built-up dirt, so it takes longer and often needs extra detail work, which is why it costs 50-100% more than a maintained visit. Once your windows are on a regular round the build-up never returns, so every clean after that is faster and cheaper.

Do I need to be home for my windows to be cleaned?

No. As long as we can reach the outside of the property and any side gates are unlocked, we can clean while you are out and let you know we have been. Most regular customers leave us to it and pay by bank transfer or card after the visit.

Is there a contract or tie-in for a regular round?

No tie-in. We text before we come so you always know when to expect us, and you can pause or stop any time. The round is meant to be easy to start and easy to leave, not a contract.
