Live Leak Repair for Chilled Water & Plumbing Pipes
A leaking pipe does not always mean a shutdown. We stop leaks on live chilled water and plumbing lines while they stay pressurized, so cooling and water supply carry on while the repair is done.
What is live leak repair?
Live leak repair (also called online leak sealing) stops a leak on a pipe, valve, flange or joint while the line is still running and under pressure. Depending on the leak, it is sealed with an engineered clamp or enclosure, or the section is isolated locally by pipe freezing and repaired, without draining the whole system.
Stop the Leak Without Stopping the System
Draining a chilled water loop or shutting a building's water supply to fix one leak costs far more than the leak itself. We pick the repair method that keeps the line in service: a sealing clamp, an enclosure, or a local freeze and replace.
- Chilled water pipes: pinhole leaks, corroded sections and weeping joints on live lines.
- Plumbing pipes: water supply, booster and riser lines that cannot be shut off.
- Valves and flanges: leaking glands, bonnets and flange gaskets.
- Leaks in plant rooms and risers where access and downtime are tight.
- Temporary seal, then permanent fix: stop the leak now and plan the permanent repair for a convenient time.
- Pipe freezing when the leaking part needs to be cut out and replaced.

Leaks We Are Called For
Chilled Water Leaks
Leaking pipes, valves and strainers on systems that must keep cooling the building.
Plumbing and Water Supply Leaks
Leaks on water supply, booster and riser lines in occupied towers and villas.
Recurring Leaks
Joints that keep weeping after past repairs, where we find and fix the underlying cause.
How a Live Leak Repair Runs
- Inspect. We check the leak, pipe material, size, pressure, temperature and the condition around it.
- Choose the method. Sealing clamp, enclosure or local freeze and replace, whichever suits the pipe and the leak.
- Contain. We protect the area and control the water while we work.
- Repair under pressure. The leak is sealed or the section replaced while the rest of the system keeps running.
- Test and report. We confirm the repair holds and tell you if a permanent fix should be planned.
Frequently Asked Questions
Do you need to shut down or drain the system?
Usually not. Most leaks can be sealed while the line stays under pressure. Where a part must be replaced, pipe freezing isolates just that section.
Do you repair plumbing leaks as well as chilled water?
Yes. We repair leaks on water supply, booster and riser lines as well as chilled water pipes.
Is a live repair permanent?
Many are. Where a clamp is a temporary measure, we tell you and plan the permanent repair at a time that suits you.
Can you help with an urgent leak?
Yes. Send us the details through the quote form or email with photos of the leak, and we will respond as quickly as we can.
Which areas do you cover?
We take on projects across the UAE, run from our office in Al Qusais Industrial Area 5, Dubai.
