The only 5 best window cleaning services in London that left my glass streak-free

Let’s be honest – cleaning windows is right up there with doing dishes on the list of things nobody wants to do. But it’s also inescapable. I found that out when I stopped doing it until I realised I couldn’t tell if it was raining outside anymore!

Now, if you’re like me and still don’t want to do the job yourself anyway, there are always window cleaners. But believe it or not, some of them are just better than others at getting a streak-free clean down.

Here are the ones our team found to do the most consistent work over multiple engagements and tests. Most of them also handle both private and commercial jobs!

How much does window cleaning cost in London?

The cost of window cleaning in London ranges from £35 to £100 per window type. On an hourly basis, window cleaners charge £15 to £25 per hour. The cost depends on the number and type of windows, type of property, and method of cleaning.

How we chose

  • Local Reputation: We chose companies that are the talk of the town (in a good way!). After all, if everyone’s raving about their sparkling windows, they must be doing something right.
  • Experience and Expertise: We wanted pros who have been cleaning windows since the days of foggy London town. Experienced window cleaners know the best techniques to get your windows sparkling without streaks or smudges.
  • Transparent Pricing: We picked companies that are clear about their pricing, no hidden costs or unexpected charges. 
  • Flexibility and Availability: Companies that could fit us into their schedule without a month-long wait made the cut. Flexibility is key, especially when we suddenly realise our windows look like they’ve been frosted—on the inside. 
  • Comprehensive Services: We love companies that offer a range of services, from regular window cleaning to the occasional deep cleaning. 

1. Alex & Chris Window Cleaning

Opening hours: Monday – Sunday: 8:00 AM – 8:00 PM

Website

Alex & Chris offer a wide range of services including residential and commercial window cleaning, and gutter cleaning. 

One of the reasons why we love their services is that they use traditional window cleaning methods. Using the conventional ladder-and-squeegee approach, they leave every window with a streak-free finish.

And while this approach seems time-consuming and expensive, it’s actually preferred by most Londoners for a reason. Besides, Alex & Chris have handled 15 windows in just an hour before, at a very competitive rate.

The company is insured, and if they’re unable to solve any issue that may arise, they’ll make the refund. With that said, there were instances where they failed to meet client standards – one even said that there were dry drops on the outside of his window.

Still, for something that’s with flexible scheduling and affordable rates, they remain a solid choice. 

Pros

  • Uses traditional window cleaning methods
  • Quick work
  • Competitive rates
  • Fully insured
  • Offers refunds if unable to resolve issues
  • Flexible scheduling

Cons

  • A few reports of unsatisfactory work

Alex is very professional, fast and trustworthy. He provided a very competitive quote right away, and managed to clean more than 15 windows for our building in 1 hour. He also identified an issue with our gutter system. We will definitely hire him again in the future!

The window cleaning service was absolutely outstanding! Alex has a professional positive attitude and very thorough in their work, ensuring no detail was overlooked. I highly recommend their services for anyone looking to brighten their home with crystal-clear windows.

2. NL Window Cleaners

Opening hours: Monday – Friday: 7:00 AM – 7:00 PM

Website

With over 1,200 happy clients and 8,000 working hours, NL’s expertise truly speaks for itself.

One thing we liked is their use of state-of-the-art equipment and environmentally friendly cleaning solutions. Plus, they have a thorough cleaning process and can deal with various types of windows. 

For example, they were able to clean 3rd-floor windows with ease – the client even said that they removed spider webs for them!

We also find their package rates to be fair and transparent. To give you an idea, they charge per service per window type. The maximum cost per service is posted, which prevents any issues of hidden or higher costs.

On the negative side though, this type of pricing lacks the flexibility that most clients want. Fortunately, they have a solid satisfaction guarantee, as per past clients. 

Pros

  • 1,200+ clients
  • 8,000+ working hours
  • Fair and transparent package rates
  • Satisfaction guarantee
  • Free quote

Cons

  • Package rates lack flexibility

NL Window Cleaners live up to their reputation as North London’s finest! We couldn’t be happier with the work they did cleaning our windows and clearing our guttering. Will definitely be calling on their services again!

Jamie Thomas | Google Reviews

Mo and his colleague did an excellent job with our windows. We just moved in and the windows needed a thorough clean. We were also suffering from lots of spider webs and spiders! The team took their time to clean the windows and got rid of all the webs. We are so pleased as the windows look brand new! I would definitely recommend using their service.

Horizon serves areas like Dulwich, Beckenham, Forest Hill, and more, making them accessible to many locals. On top of that, they’re very easy to book and reach via WhatsApp. 

What sets them apart is their use of premium cleaning equipment. This includes a reach-and-wash system that seems efficient, effective, and environmentally friendly. 

To give you an idea, this system ensures streak-free windows without the need for harsh detergents. Other than this, they still offer traditional cleaning services for ground-level windows (upon request).

While there are certain reports of unsatisfactory results, we appreciate their level of skill. In particular, they’re especially skilled at Velux windows, skylights, and even bifold doors. 

Finally, they offer services at rates that fall in the city average. We couldn’t complain there.

Pros

  • Serves many areas
  • Easy to book and reach via WhatsApp
  • Uses premium quality cleaning equipment
  • Doesn’t use harsh detergents
  • Offers traditional cleaning services 
  • Handles Velux windows, skylights, and bifold doors
  • Fair rates

Cons

  • Some reports of unsatisfactory results

Had some building work and wanted to get my neighbours conservatory windows and back windows cleaned. They where delighted with the results… said they’d never had such clean windows since they moved in. A professional and very personable company. Highly recommended.

Kerry Gavin | Google Reviews

Great experience – Jordan and Gina were prompt and went over and above what I’d asked them for. They even covered the cost of the skip hire which was unforeseen. Full property clean and clear out. As an estate agent this type of service is invaluable to our clients – we would highly recommend using them.

Carlos Window Cleaning offers both hand-cleaning and a reach-and-wash system with pure water. Apart from this, they also provide gutter cleaning and repair services, as well as solar panel cleaning and bird proofing.

What sets them apart is their attention to detail and commitment to customer satisfaction. Clients consistently praise their quick and efficient service, leaving windows sparkling and clear. 

Plus, their pricing is reasonable, so you can get their services without breaking the bank.

Still, like most services, they do have issues with poor quality of work – but they’re at such rare instances that they almost don’t matter. What mattered to us was how punctual they are and how reliable they are when it comes to all services.

Last but not the least, the company is also protected by insurance, which means you can rest assured even if there’s harm to your products or property resulting from their services. Thankfully, none of their past clients have had major issues to need this. 

Pros

  • Offers both hand-cleaning and reach and wash system with pure water
  • Solid set of services
  • Quick and efficient service
  • Reasonable pricing
  • Punctual and reliable

Cons

  • Minor issue of poor quality of work

Exceptional service! Carlos did an outstanding job – quick, efficient and left my windows sparkling. His pricing is very reasonable too. I highly recommend Carlos for anyone in need of top notch window cleaning!

Rebecca Howard | Google Reviews

We were extremely satisfied with Carlos – he very quickly responded to our cleaning ask and we managed to arrange a clean within 48Hrs. All our windows (2nd floor house) were cleaned to an exceptionally good standard (still shining!) and the price was much better than comparable cleaners. We highly recommend Carlos to anyone looking to get their windows cleaned at a reasonable price in the Warwick Avenue/Maida Vale area!

Opening hours: Monday – Friday: 6:00 AM – 8:00 PM

From residential homes to commercial properties, KM Window Cleaning covers a wide range of services. Apart from window cleaning, they also offer gutter cleaning and solar panel maintenance.

During our visits, we saw how respectful they are when working on properties. They also appear to take extra precautions to protect all surfaces and ensure minimal intrusion when working with homes.

Another thing that earned a point from us was their flexibility and responsiveness. Not only are they prompt, but they always finish within the promised timeframe.

According to the clients we spoke to, their rates are pretty reasonable. However, since they’re not very upfront about it, we see how there’s a small risk of hidden costs or unexpectedly high costs. 

Fortunately, they make scheduling and follow-ups easy. Plus, they always keep their clients in the loop in case they have additional requests for window cleaning. 

Pros

  • Offers a wide range of services
  • Minimal intrusions
  • Takes extra precautions
  • Easy scheduling and follow-ups
  • Reasonable rates

Cons

  • Not upfront with pricing 

KM Window Cleaning did a great job at the property I’m working. Chris and wife are very punctual and did the job very professionally. They have excellent work ethic and having hired so many window cleaner in the past, I can honestly say they are the best. I highly recommend them and for sure I’m doing to hire them again in the future. They deserve a 10 star!

Edna Torrado | Google Reviews

Communication before the visit was fantastic, Chris and his partner were polite and friendly and have done an absolutely amazing job – really thorough, careful and respectful of our property and have left our windows looking brand new. We’re delighted and will be recommending them to all of our local friends!
