Hull-based Kingston Cleaning Services (KCS) was contracted by developer Wykeland Group to deliver a programme of sensitive cleaning works to smarten up landmark buildings in Hull city centre.
The frontages of the former Marks & Spencer store and the property sub-divided between HMV and the former New Look unit, on Whitefriargate, as well as the old central police station in adjoining Parliament Street, have all received a facelift.
KCS carried out the works, with its operatives employing a cleaning system that produces a high-pressure steam to quickly but gently remove grime, dirt and moss.
The specialist system is chemical-free and is designed specifically for conservation work that removes grime and dirt without damaging the limestone.
The cleaning, including of the pillars of the former M&S store, was carried out between 6pm and midnight over several nights to avoid disruption to the public and ensure COVID-19 social distancing guidelines could be adhered to.
Sean Carrison, Managing Director of KCS, said: “Because of the historical significance of the buildings we, used a less aggressive, softer way of cleaning that doesn’t involve any harmful products.
“It is very effective, without causing any damage to the stone, making the buildings much brighter and more attractive.”
KCS has carried out a number of other restorative cleans in recent months, including buildings in Edinburgh for The Lloyds Banking Group and The Scottish Widows Building.
