We’ve been working with businesses of all shapes and sizes across Greater London for over 20 years. Delivering outstanding cleaning services to each and every one of them. From entire office floors in the high rise buildings of London’s business district to hospital wards dotted across the capital, we have done it all.
It is this experience that places us as industry leaders in London when it comes to contract cleaning services. Our attention for detail ensures that all of our clients are regularly delighted with the standard that their premises are transformed into. As a result of the regular and rigorous training, our staff are highly qualified in their fields of cleaning. This means they are more than adept at tackling whatever cleaning task is at hand, no matter the shock-factor!
As your chosen contract cleaners, we see ourselves as an extension of your business, which means embracing what makes your business so special. You deserve not only the highest standard cleaning, but also communication and customer service.
While the core of our business is focused on contract cleaning in London, over the years we have begun expanding our service catchment area into the surrounding counties. This has proven very helpful for businesses with multiple premises within and outside of the capital.
Our servicing area includes London, Surrey, Hertfordshire, Berkshire, Essex, Kent, Buckinghamshire. If you’re not located within one of these locations, please get in touch with us and we will try our best to find a solution that works for both parties.
Our client list over the years has seen businesses from all walks of life. Having specialist cleaners in our ranks for a wide range of cleaning tasks means we’ve seen it all.
We have worked with more straightforward business who simply require their office to be cleaned regularly as well as landlord who want their properties space returned to its former glory after a long tenancy. But on top of this, we are also adept at the more odd cleaning tasks. From graffiti cleaning to food plant cleaning, we can do it all. Just get in touch with our team.
