It's one of the questions we get asked most often when setting up a new regular customer — "how often should I actually have my windows done?" The honest answer is: it depends on your property and what's around it, but for most Derby homes, every 4–6 weeks is the sweet spot.
Here's how to work out what's right for your situation.
| Situation | Recommended frequency |
|---|---|
| Busy main road or near a junction | Every 4 weeks |
| Standard residential street | Every 4–6 weeks |
| Quiet close or cul-de-sac | Every 6–8 weeks |
| Rural property near farmland | Every 4 weeks (dust, pollen, spray) |
| Property with heavy tree coverage | Every 4 weeks (sap, pollen, bird activity) |
| Coastal property (salt spray) | Every 3–4 weeks |
Most Derby residential areas — Chaddesden, Spondon, Chellaston, Alvaston, Shelton Lock — fall into the "standard residential" category. A 4–6 week schedule gives consistently clean windows without over-servicing.
Understanding what's dirtying your windows helps you dial in the right frequency:
Traditional window cleaning uses a squeegee and a cleaning solution — fast and effective, but the rubber leaves trace residue on the glass, and any solution left on the frame or sill can cause streaking or long-term staining.
The industry standard for residential cleaning in the UK has shifted significantly toward pure (deionised) water systems — and for good reason:
Pure water has had all minerals removed, so when it dries it leaves nothing behind. This is why windows cleaned with a pure water system often look better for longer — there's no residue to attract fresh dirt.
No — you don't need to be home at all. A professional cleaner will work around the exterior with a reach pole. If you have any windows you need cleaned internally, you'd need to be home for that visit, but external cleaning is completely independent.
Most regular customers set up a standing schedule — say, the first Tuesday of every month — and payment is handled by bank transfer or standing order. You come home to clean windows without needing to arrange anything.
A standard clean should cover:
Internal cleaning is usually an additional service and requires access to each room. Most customers have an internal clean once or twice a year — at a spring-clean and pre-Christmas — and maintain externals monthly throughout the year.
One of the most common questions — and the answer might surprise you. Rain on a pure-water clean within the first hour or two can leave some spotting, depending on local water quality. But once the glass is completely dry, rain generally doesn't affect the result significantly. In fact, rain washes off surface dust without leaving deposits — unlike in coastal areas where rain carries salt.
A good window cleaner won't clean if heavy rain is actively falling, but a shower shortly after a clean is not usually cause for concern.
We run regular monthly and 6-weekly rounds across Derby, Chaddesden, Chellaston, Spondon and Alvaston. First clean, then set up a standing schedule — no hassle.
Every 4–6 weeks is the most common schedule for residential properties. Homes near busy roads, farms or with heavy tree coverage often benefit from monthly cleans.
Yes. Pure water cleaning gives a streak-free, residue-free finish that lasts longer than a DIY clean with tap water. It also covers upper floors safely and includes frames and sills as standard.
Usually residue from the previous clean — either from squeegee rubber or tap water minerals — is attracting fresh dirt faster. Pure water cleaning eliminates this because it leaves absolutely nothing on the glass.
They should — frames and outer sills should always be included in a standard clean. If a quote doesn't mention them, ask before booking.
