Office and Common Area Cleaning
We can help you present your offices or managed common areas in pristine condition. We are also taking significant steps towards providing a more hygienic office environment to help reduce sickness and increase employee wellbeing. 

Window Cleaning
Our fully trained and highly experienced window cleaners are able to clean internal and external windows using a range of methods including traditional, water fed poles, cradles and abseiling.

Carpets Cleaning and Stone Maintenance and Restoration
Our highly experienced carpet and stone maintenance teams can help with the cleaning, restoration or maintenance of these high value surfaces. Please see our Expert Services page for more details.

Waste Collection and Recycling
We can help with recycling initiatives and practices to help aim for zero waste. We take waste compliance seriously and keep all legally required documentation. We make it our business to know the final destination of the waste we collect.

External Maintenance
First impressions count. The cleanliness of the outside of a building is as important as the inside. We can jet wash, scrub or remove graffiti from a range of surfaces. We also offer a protection application to make it easier to remove subsequent attacks.

Washroom and Janitorial Supplies
We can deal with all washroom hygiene issues including supplying soap and hand towel dispensers, air fresheners and sanitary bins. We have selected an environmentally friendly service provider for these. 

Daytime staff and janitors
We pay particular attention to the recruitment and training of our daytime staff and janitors. They are the highly visible ambassadors of our clients and of us. Part of their training includes a customer care focus. All staff our smart, presentable, speak good English and carry out their work with a smile.

Right First Time Solutions is our priority. We spend time looking at each client’s individual requirements to ensure we come up with the best possible solution and provide added value. We have regular client review meetings and conduct quality audits.
