Our brand values and vision

We want to change perceptions of the window cleaning industry to bring it in line with other customer service-driven sectors. It’s worked for takeaways and taxis, and it’s working for us too!


Our core values, which underpin our whole business, include:



While we’re a very modern business, good old-fashioned service excellence is what MWC is known for, and what our franchise partners are passionate about



Professionalism and consistency are keys to success. From our branding to our technology, everything we do lets customers know they can rely on us



This is hugely important to establishing quality relationships with customers, with suppliers and between franchise partners - and it's crucial for repeat business



We love local communities and our aim is that window cleaners return to becoming a big part of them, just as they were many years ago

Meet the Directors


Karen Prewer, Founder and Managing Director

Karen started her professional career in the city of London working as a broker in the financial markets. Like thousands of other homeowners across the UK, she found it almost impossible to find a great, reliable window cleaner. When she did, they seemed to stick around for a few months before disappearing. There were always issues regarding cash payment collections and she never knew when they were going to turn up. As all great entrepreneurs do, Karen said “I can do this better” and she has.

Twenty-five years later, there are thousands of happy My Window Cleaner customers across the UK, enjoying a very different quality of service and experience. Karen realised that along with reliability and an exceptional standard of work -systems, processes and technology were fundamental to create a scalable business opportunity. This experience has led to the creation of Gloria, our cloud-based CRM system, that allows a franchise owners to have the same business scalability and unique service offering for their customers.
