Quality, friendly service and pride in our work have

been the cornerstones of our business since 1996

My Window Cleaner was founded in 1996 by Karen Prewer after she found it impossible to find a quality, reliable window cleaner and knew that others must be in the same boat. It turns out that her instincts were right! Today Karen and her team count over 4,000 households as loyal customers across north London and Hertfordshire.


All My Window Cleaner operatives arrive in professional liveried vans, wear branded clothing and carry photo ID cards so you know exactly who they are. They’re fully trained to the highest standards, committed to health & safety best practice, and are covered by public liability insurance.

Thanks to the passion of our team, we’re so confident in the standard of their work that we guarantee you’ll always be happy; if for any reason you’re not, we’ll promptly return to re-clean, at no cost to you.

Bringing window cleaning services into the 21st century

My Window Cleaner: high quality, great value

We believe there’s no excuse for a window cleaning service that doesn’t have the customer at its heart. For too long it’s been a sector filled with undependable operators where you don’t know their name, when they’ll arrive or even if they have insurance cover. In 2020, that seems crazy to us!

My Window Cleaner changes all that by using bespoke technology that keeps you in control, backed by window cleaners that care about delivering great service every time.

We make it easy for you to get a quote, and our head office team communicate clearly who will be there to do your cleaning and when – you’ll receive an email to remind you we’re coming before every single clean.

We want to change the face of window cleaning in the UK. Put us to the test and say hello to a new way of doing things.
