Riser Cleaning

Accessing and maintaining Extract Risers can be challenging due to central placement or attachment to the outer wall.

What is Riser Cleaning?

Riser cleaning refers to the maintenance and cleaning of a building's vertical utility shafts or risers. Extract Risers have always been notoriously difficult to access, inspect and maintain due to their positioning either through the centre of a building or bolted onto the exterior wall. Also, their height and roof access are often problematic issues.

How does it work?

Overview of the Process

We have our Hot Chemical Viscosity (HCV) Riser Cleaning method, designed to tackle stubborn grease build-up efficiently. This process begins by cordoning off the area, heating, and diluting a potent chemical solution that breaks down even the most resilient grease deposits.

When safe roof access is unavailable, we employ a compactable lift system to securely reach the riser discharge point. The chemical solution is then carefully pumped down the riser, capturing the grease and chemical mixture at the bottom. This collected residue is safely stored and later removed off-site.

What do we do?

Service We Offer

Our HCV Riser Cleaning procedure offers a cost-effective alternative to the expensive requirements of scaffolding or abseiling. Its portability, convenience, and guarantee of effective grease removal have made it a preferred choice among national restaurant and pub chains, shopping centres, and commercial buildings throughout the country.

We inspect, test, clean and provide the necessary documentation to ensure that records are always kept fully up to date and compliance is achieved.
