All office cleaning tasks receive an individual worksheet designed around your personal requirements. This includes a supervisory record where all work is checked and monitored at all times; janitorial product levels can be checked and re-stocked as needed and kitchen consumables such as tea, coffee, soap, hand towels can all be provided whenever needed.

WOW! What a delightful surprise we all had this morning! Walking into a kitchen that smelled CLEAN was quite marvellous for me :) There have been numerous comments from staff saying we must have new cleaners. I can’t give you higher praise than that!”
