Leak Detection
Hidden water leaks located with thermal imaging and acoustic equipment, so the repair starts in the right place.
Leaking or Cold Radiator? Repaired or Replaced

Plumbing Work on Pipes and Valves
Leaking valves, weeping radiators, cold spots and radiator swaps, handled as plumbing on the pipes and radiators themselves. Vision Plumbing does no gas work, so the appliance that heats the water is a gas engineer's job.
Signs It Is Time To Call
- Water around a radiator valve or on the floor below
- Rust-coloured staining on the radiator or pipe
- A radiator cold at the top while the rest is warm
- A valve that will not turn or snaps when forced
- One radiator stays cold while the others heat up
- Hissing or gurgling from the radiators
Radiators are plumbing work
A radiator is a steel panel full of water, connected by two valves to a pair of pipes. Norbert covers everything between the flow and the return across Kent, Medway, Surrey, Sussex and south-east London.
- Valves, joints, pipe runs and the radiators themselves
- Leaks, stuck valves, cold radiators and replacements
- No gas work, so appliance faults go to a gas engineer
Radiator leak repair
A leaking radiator is almost never leaking where the puddle is. Water runs along the valve and pipe before dripping, so the first job is finding the real source.
- Usual sources: spindle gland, compression nut, radiator tail or panel pinhole
- Valve and joint leaks fixed by remaking, repacking or replacing
- A pinholed panel means a new radiator
- Hidden underfloor leaks found with thermal imaging leak detection, not lifted boards
Radiator replacement and installation
Old radiators corrode from the inside, and a panel that has pinholed or gone brown at the seams is on its way out. A new one can be the same size, larger or a different style.
- Isolate, drain down, swap the panel, adapt the pipework, refill and vent
- Larger or different styles, provided the pipework can supply them
- Extra or moved radiators, with the pipe route explained first
Valves, bleeding and cold spots
Seized valves, snapped lockshields and thermostatic valves stuck shut are common on radiators left alone for years. These small jobs fit alongside any other general plumbing services on the same visit.
- A cold top means trapped air and a bleed
- One cold radiator often has a stuck valve pin
- All work carries a one year warranty on parts and labour

Radiator Repair & Installation: questions answered
01Why is my radiator leaking from the valve?
Most valve leaks come from the gland around the spindle, which dries out and lets water weep past, or from the compression nut where the valve meets the pipe or the radiator tail. Sometimes a gentle tighten is enough. If the gland is worn or the olive has deformed, the valve needs repacking or replacing, which means draining down that part of the system first.
02Is it worth fixing a radiator that is leaking from the body?
Usually not. A leak from the panel itself, normally a pinhole along a seam, is corrosion from the inside, and where one pinhole has appeared others tend to follow. Sealants rarely give a lasting fix. Replacing the radiator is the dependable repair. If the leak is at a valve or joint instead, that is a much smaller job and well worth fixing.
03Why is my radiator cold at the top but warm at the bottom?
That pattern almost always means air trapped at the top of the radiator. Bleeding it through the vent at the top corner lets the air out so water can fill the whole panel. If it keeps coming back quickly, there may be a small leak elsewhere letting air in, or a pressure problem worth having looked at.
04Can you replace a radiator with a different size?
Yes. A new radiator rarely lines up exactly with the old pipe centres, so Norbert adapts the pipework or fits valve extensions to suit. Going bigger or choosing a different style is possible, as long as the pipework can supply it. He will point out anything about the wall, such as a stud partition, that affects how a heavier radiator is fixed.
05One radiator stays cold when the others are hot. What is wrong?
The usual causes are a stuck thermostatic valve pin, a lockshield valve closed too far, or air in that radiator. Each is plumbing work on the radiator itself and usually a quick fix. If every radiator in the house is cold, the problem is more likely to be with what heats the water, and that is a job for a gas engineer rather than a plumber.
06Does radiator work include the appliance that heats the water?
No. Vision Plumbing does no gas or boiler work of any kind. Radiator work covers the radiators, their valves and the pipes that feed them. If a fault turns out to be with the appliance that heats the system, you will need a registered gas engineer for it, and Norbert will say so plainly rather than attempt it.
