The 5 Best Window Washers in London That Will Make Your Glass Shine Again
Before I got my windows professionally cleaned, I didn’t think much about the state of my glass until the marks started getting harder to ignore.
My view looked a bit dull; the rain left stubborn spots, and over time, city dust started building up around the panes and frames.
Nothing extreme, but it made me curious about proper cleaning services. That’s when I started looking into window washers, comparing prices, checking reviews, and seeing who could actually handle the town’s weather and grime properly.
I put together a guide to the best window washers in London. Trust me, these picks are worth checking out!
How much does window washing cost in London?
In London, window washing usually costs between £20 and £45 for regular residential maintenance, depending on the size of your home and the number of windows.
1. ALEX&CHRIS WINDOW CLEANING LTD
Website: https://alexchriswindowcleaning.co.uk/
Address: Flat 15 Aldenham Court Edgware HA8 8FY
Contact: +44 7459 609893
Hours: Monday to Sunday: 8:30 AM to 8:00 PM
Most property owners I spoke to described ALEX&CHRIS WINDOW CLEANING LTD the same way: you get a careful clean, but with a more modern finish.
Their service combines traditional hand-washing with pure water technology, which makes them a strong option for London homes dealing with stubborn city grime.
It’s very useful on terraced houses, flats, and exterior glass that constantly picks up dust and rain spots.
I like that their filtration setup removes tiny impurities from the water, allowing the glass to dry naturally without leaving mineral streaks behind.
That efficient approach carries through during the actual visit. When I hired them to check a tricky rear window on my property, the crew arrived exactly on time and worked quickly.
Nonetheless, it’s worth noting that they don’t cover the entire capital, so you’ll need to check if they service your borough before booking.

2. Shine Bright Cleaning
Website: https://sbwcleaning.co.uk/
Address: 22 Notting Hill Gate
Contact: 020 3151 0796
Hours: Monday to Friday: 8:00 AM to 5:00 PM
Shine Bright Cleaning keeps property maintenance simple with a family-run approach that feels friendly and reassuring.
Their biggest standout is the satisfaction guarantee, which allows them to fix any issues for free as long as you report them within three days.
I particularly like how easy they make the whole process here, especially for busy homeowners. Their website gives you an instant quote in less than a minute, and the online booking system keeps everything straightforward from there.
Their technicians are also fully insured, adding peace of mind when they’re working around your windows and property.
Regular customers may benefit most from their maintenance packages, since signing up can save you over thirty per cent on ongoing cleaning.
Still, the guarantee comes with a short reporting window. If you notice a problem after three days, the free fix no longer applies.

Did a great job cleaning up
Shine Bright are lovely and friendly and did a great job cleaning up after the renovations were done on our new home. Andre cleaned the windows and gutters so we don’t have to worry about them for a while, and Shamaianne took great care to get rid of all the dust and paint smudges left by the contractors.

3. The City Window Cleaning Specialists

Address: 124 City Rd
Contact: 07852106858; 07852106852
Hours: Monday – Friday: Open 24 hours
The City Window Cleaning Specialists is a solid choice if you like clear pricing and no surprise charges.
A big part of their appeal is how upfront they are. People who value transparency will appreciate that they offer a wide range of exterior cleaning options while keeping their quotes honest and easy to understand.
They’re also open 24 hours a day, which makes scheduling much more flexible, especially if you need work done outside normal business hours.
A colleague of mine used them for an office building, and she said the technicians arrived right at midnight to avoid disrupting regular trade.
Their team uses a smart mix of traditional tools and modern equipment, so they can handle everything from regular home windows to high-level commercial cleaning.
Just a heads-up: if you need complex abseiling work during peak season, you have to book in advance.

4. The London Window Cleaning Company
Website: https://thelondonwindowcleaningcompany.co.uk/
Address: 136-144 New Kings Rd
Contact: 020 3026 5489
Hours: Monday to Sunday: 8:00 AM to 7:00 PM
For a safer window cleaning solution that can reach up to 65 feet, I’d say The London Window Cleaning Company is a great option. They use specialised ground-based equipment instead of sending technicians up shaky ladders.
With strict compliance with EEC and HSE Work at Height regulations, they’re a good fit for homes where high glass feels risky to clean.
The setup is surprisingly practical. Their equipment keeps staff safely on the ground, reaches taller exterior windows, and still leaves the glass looking spotless.
For more detailed jobs, they also clean the frames thoroughly, which is useful before new tenants move into a property.
The main limit is their 65-foot height cap. If your windows sit higher than that, they won’t be able to take the job.

Did an excellent and speedy job of cleaning 7 large sash windows
I hired the London Window Company to clean 7 windows in my flat in Central London. They communicated that they would arrive later than expected. On arrival Felipe and his assistant did an excellent and speedy job of cleaning 7 large sash windows on the first floor (both inside and outside). Based on my experience, I would have no hesitation in recommending them.

Professional, clean and friendly
We always use The London Window Cleaning Company for our window cleaning, and we have a lot of windows! The guys are always professional, clean and friendly. The price is excellent and very good value for money considering that they need to spend nearly the whole day on site. I have no hesitation in recommending them, They do a great job and leave our windows sparkling, inside and out. Nothing is too much trouble and they ensure we’re happy with the service provided before leaving.

5. Squeaky Clean Windows
Website: https://www.squeakycleanlondon.co.uk/
Address: Rifle St
Contact: 07930 119920
Hours: Monday – Sunday: 8:00 AM – 7:00 PM
Squeaky Clean Windows makes sure every property gets a clearer, greener window-cleaning solution.
People I looked into said their team can accommodate different spaces, from regular homes to commercial properties, without relying on harsh chemical-heavy methods.
What intrigued me most is how their cleaning approach works together.
You get traditional hand-cleaning where needed, advanced water-fed pole systems for a high-definition finish, and environmentally sound results without chemical residues left behind.
I also like that their technicians are fully trained and comprehensively insured, which gives property owners extra peace of mind during the service.
They can even help with exterior extras like conservatory washing and gutter clearance.
To start, you can book a free site visit for a personalised, no-obligation quote.
Sadly, their reach has limits. Their water-fed pole setup only extends up to 60 feet, so they can’t service taller commercial buildings or high-rise apartments.
