Most modern UK window cleaners have transitioned from traditional ladders and squeegees to "reach and wash" water-fed pole systems. This guide explains what to expect from a professional service, the current market rates for 2025/26, and how to ensure you get a streak-free finish every time.
What Does the Work Involve?
- Initial Assessment: The cleaner inspects the property for access issues, fragile glazing, or pre-existing damage like "blown" double glazing units.
- Frame and Sill Prep: High-quality services include brushing down frames, sills, and vents to remove loose debris before wetting the glass.
- Pure Water Cleaning: Using a telescopic pole, the cleaner applies de-ionised water which absorbs dirt and dries naturally without leaving spots or streaks.
- Traditional Squeegee (Optional): For interior glass or specific ground-floor windows, a manual applicator and squeegee may be used for a polished finish.
- Door and Surround Wipe: Standard contracts usually include wiping down front and back doors, including the frames and threshold.
- Maintenance Check: Professional cleaners often alert homeowners to failing mastic, cracked panes, or blocked guttering noticed during the process.
Typical Costs
| Service Type | Low £ | High £ | Notes |
|---|---|---|---|
| 2-Bed Terrace (Exterior) | £15 | £25 | Standard monthly or 8-weekly cycle. |
| 3-Bed Semi (Exterior) | £20 | £35 | Most common UK property type. |
| 4/5-Bed Detached (Exterior) | £35 | £60 | Includes multiple elevations and more glass. |
| First-Time Clean Surcharge | £15 | £40 | One-off fee to clear heavy build-up. |
| Interior Glass Cleaning | £20 | £50 | Usually doubles the exterior price. |
| Conservatory Roof | £50 | £150 | Price varies by size and algae levels. |
Prices are influenced primarily by the number of windows, the frequency of the visit, and ease of access. Expect to pay a premium for properties with three or more storeys or homes requiring specific safety equipment.
How Long Does It Take?
- Small Terrace/Flat: 15–25 minutes for a routine exterior clean.
- Average 3-Bed Semi: 30–45 minutes using a water-fed pole system.
- Large Detached Home: 60–90 minutes depending on conservatory and outbuildings.
- First Clean/Deep Clean: Add 50% to the standard time to account for scrubbing neglected frames.
DIY or Professional?
While cleaning ground-floor windows is a straightforward DIY task, professional cleaners offer significant advantages in safety and results. Reaching second-storey windows or conservatory roofs requires specialist ladders or expensive water-purification systems to avoid "spotting" caused by hard tap water.
Professional window cleaners are familiar with the Working at Height Regulations 2005, ensuring the job is done safely without risking a fall or damaging your property with heavy ladders.
Choosing the Right Tradesperson
- Insurance: Ensure they hold Public Liability Insurance (minimum £1m) that specifically covers "damage to items being worked upon."
- Payment Methods: Reputable modern cleaners often use automated systems like GoCardless or bank transfers rather than knocking for cash in the evening.
- Reliability: Look for cleaners who send a text notification the night before they arrive so you can unlock gates.
- Questions to Ask: Do you clean the frames and sills as standard? What is your policy if it rains? Are you insured to work on my specific roof type?
UK Regulations
- Working at Height Regulations 2005: This encourages the use of water-fed poles over ladders wherever "reasonably practicable" to minimise fall risks.
- GDPR: If your cleaner stores your phone number or address for scheduling, they must comply with UK data protection laws.
- Public Liability: While not a legal requirement for sole traders, it is an industry standard to protect the homeowner’s property.
Common Problems
- Spotting on Glass: Usually caused by the cleaner using "dirty" water (high TDS levels) or failing to rinse the frames properly, allowing dirt to bleed onto the glass.
- Access Issues: Locked side gates are the most common reason for missed windows; always ensure the cleaner has full access on their scheduled day.
- Damaged Seals: High-pressure washing can sometimes worsen existing "blown" double glazing units where the vacuum seal has already failed.
- Inconsistent Schedules: Some "round" cleaners may skip visits during winter months; establish a firm 4, 6, or 8-week frequency upfront.
Frequently Asked Questions
Can my windows be cleaned if it is raining?
Yes. Modern pure-water systems work perfectly well in light to moderate rain. Since the water is already purified, rainwater (which is relatively pure) won't affect the streak-free finish unless there is a heavy storm or high winds.
Why do my windows look spotted after the very first clean?
On the first clean, the pure water often draws out decades of old soap residue and dirt trapped in the rubber seals. This can sometimes run onto the glass as it dries, but it usually disappears by the second or third regular clean.
Do I need to be home for the cleaner?
Only if you require interior cleaning. For standard exterior cleans, most professionals simply require access to the perimeter of the property and will leave a card or send a text once the work is completed.
What is "Pure Water" cleaning?
It is tap water that has been filtered through a de-ionisation resin to remove minerals like calcium and magnesium. Because the water is "hungry" for minerals, it lifts dirt off the glass and dries completely clear without needing to be wiped dry.
Will a window cleaner also clean my gutters?
Many window cleaners offer gutter clearing and fascia cleaning as an add-on service, but it is rarely included in the standard window cleaning price. Always ask for a separate quote for these tasks.
