“Union Street Technologies Limited has employed the services of Mainstream Cleaning since 2015, and I have been delighted with the service, both on a regular basis and the occasional one-off service. In all that time, I have found every interaction with Mainstream to be not only professional and efficient but also friendly.
I have no hesitation in recommending this company for all aspects of cleaning requirements.”
