Maintaining the exterior of your home starts with the windows. While it might seem like a purely aesthetic task, professional window cleaning removes corrosive ...
For UK homeowners, a full external clean ensures your property maintains its curb appeal while protecting the lifespan of expensive uPVC, timber, or aluminium frames. Modern techniques using purified water provide a streak-free finish that stays cleaner for longer than traditional soapy methods.
What Does the Work Involve?
- Initial Inspection: Assessing glass condition, identifying damaged seals, and checking for difficult-to-reach areas.
- Surface Preparation: Removing loose debris, cobwebs, and dust from the glass, frames, and sills.
- Pure Water Cleaning: Using water-fed poles to scrub the glass with deionised water, which absorbs dirt and dries without leaving spots.
- Deep Cleaning: Treating stubborn deposits like bird lime, lichen, or paint splashes with specialist non-abrasive cleaners.
- Frame and Sill Wipe-down: Ensuring the entire window unit—not just the glass—is cleaned to prevent dirt from running back onto the panes.
- Specialist Areas: Cleaning conservatory roofs, skylights, and French doors using appropriate reach-and-wash equipment.
Typical Costs
| Item | Low £ | High £ | Notes |
|---|---|---|---|
| Minimum Call-out Fee | £40 | £70 | Covers travel and basic setup for small jobs. |
| 2-Bed Terrace / Flat | £50 | £90 | Standard external glass and frames. |
| 3-Bed Semi-Detached | £70 | £130 | Includes standard windows and front/back doors. |
| 4-5 Bed Detached | £120 | £280 | Varies based on number of windows and access. |
| Conservatory Roof Clean | £60 | £180 | Depends on size and level of algae growth. |
| Specialist Access (MEWP) | £250 | £500 | Required for high-rise or restricted access. |
Prices are influenced primarily by the size of the property and the frequency of the clean. A "one-off" deep clean is significantly more expensive than a regular 4-weekly or 8-weekly service because of the heavier accumulation of grime.
How Long Does It Take?
- Small Terrace or Flat: 30 to 60 minutes.
- Standard 3-Bed Semi: 1 to 2 hours.
- Large Detached Property: 2 to 4 hours.
- Full Conservatory Roof: 1 to 3 hours depending on moss levels.
DIY or Professional?
Cleaning ground-floor windows is a manageable DIY task, but upper floors present significant safety risks. Professional cleaners use Water-Fed Pole (WFP) systems, allowing them to work safely from the ground while reaching heights of up to 60 feet.
Professional pure water systems remove the minerals found in tap water, ensuring your windows dry perfectly clear without the need for manual squeegeeing.
If you choose to use ladders yourself, you must follow the HSE Safe Use of Ladders guidance. However, hiring a professional ensures the frames and sills are treated correctly without risking damage to your property or personal injury.
Choosing the Right Tradesperson
- Check Insurance: Ensure they hold Public Liability insurance specifically covering "working at height."
- Verify Methods: Ask if they use purified water or traditional mops; pure water is generally better for modern uPVC.
- Read Reviews: Look for reliability and punctuality, as window cleaning is often a recurring service.
- Ask about "Extras": Confirm if frames, sills, and doors are included in the quoted price.
- Payment Terms: Most modern cleaners offer GoCardless or bank transfers rather than cash-on-the-door.
UK Regulations
- Work at Height Regulations 2005: This requires professionals to avoid working at height if there is a safer alternative (like water-fed poles).
- Health and Safety at Work Act: Contractors must provide a safe environment for themselves and the public.
- GDPR: If they store your contact details for a regular round, they must comply with UK data protection laws.
Common Problems
- Water Spotting: Usually caused by using "hard" tap water or failing to rinse the glass sufficiently.
- Damaged Seals: High-pressure washing (not recommended) can blow out window seals, leading to misted double glazing.
- Scratched Glass: Occurs when grit is moved around the pane with a dirty cloth or incorrect scraper.
- Access Issues: Locked gates or overgrown bushes can prevent a full clean; ensure the perimeter is clear before the visit.
Frequently Asked Questions
Can windows be cleaned in the rain?
Yes, professional window cleaners can work in light to moderate rain. Since they use purified water, the rainwater (which is also relatively pure) does not affect the finish, though high winds may stop work for safety reasons.
Why are my windows spotted after the first pure water clean?
If your windows were previously cleaned with soap, the first pure water clean may draw out old detergent residue from the seals. This usually disappears after the second or third professional clean.
Do I need to be home for the cleaning?
No, as long as the cleaner has access to the exterior of the property and all gates are unlocked. Most cleaners will text the day before to remind you to clear access.
How often should I have my windows cleaned?
Most UK homeowners opt for a 4-weekly or 8-weekly schedule. Properties near the coast or busy main roads may require more frequent visits due to salt or traffic film.
Does window cleaning include the gutters?
Generally, no. Gutter clearing is a separate service that involves removing debris from the inside of the channels. However, most window cleaners offer "Gutter, Fascia, and Soffit" cleaning as an add-on.
