ABOUT YORKSHIRE PIPE FREEZING
Sheffield-based pipe isolation engineers for commercial sites.
Yorkshire Pipe Freezing was set up by Sheffield-based engineers with over a decade of hands-on experience in commercial and industrial pipework systems. Since 2014, the team has worked across factories, healthcare, education and critical infrastructure, where safe live-system work and clear planning matter.
We focus on two specialist services: liquid nitrogen pipe freezing and line stopping. The work is for contractors who need a section of live pipework isolated without draining the whole system or stopping the rest of the building.
Built on a straight-talking, practical approach, we help commercial and industrial teams keep programmes moving across Yorkshire and Manchester.

Frequently Asked Questions
Find expert answers about pipe freezing, line stopping, and emergency pipework isolation services across Yorkshire and Manchester.
How does pipe freezing work?
Pipe freezing creates a temporary ice plug inside the pipe using liquid nitrogen. This allows you to carry out repairs or valve changes without needing to drain down the entire system.
Is pipe freezing safe?
Yes, it is a standard industry method for isolating pipes. We use professional equipment and follow a strict method statement to ensure the work is completed correctly without damaging your pipework.
Do you offer emergency call-outs?
Yes. We provide urgent call-outs for live pipework isolation across Yorkshire and Manchester for fast repairs. For urgent enquiries, call 07547 116918.
What details should I send for a quote?
To provide an accurate price, we need to know the pipe material, the pipe size (between 1/2 inch and 4 inch), the location of the site, and the type of system (e.g., LTHW or chilled water).
Why use Yorkshire Pipe Freezing?
With over ten years of experience handling commercial pipework in Sheffield, we offer a straight-talking, reliable service to get the job done right for mechanical contractors.
What pipe sizes can you freeze?
We manage commercial and industrial systems with pipe sizes ranging from 1/2 inch to 4 inch. This includes chilled water, heating, and LTHW lines.
Which areas do you cover?
We are based in Sheffield and serve all of Yorkshire and Manchester. Our teams regularly work on sites in Leeds, York, Doncaster, Barnsley, and Rotherham.
Can you isolate live pipework without shutting down?
Yes. Freezing the pipe creates a solid internal plug so you can isolate a specific section and work on it while the rest of the site remains operational.
What is line stopping?
Line stopping is another professional method used to isolate live pipes. We use it to block a section of the system for maintenance or upgrades while the rest of the network stays live.
Will the pipe burst?
No. Pipes only burst when water is trapped and freezes naturally. We check pipe material and pressure first, using liquid nitrogen to create a safe ice plug without causing damage.
