Radiator & Heating Leak Repair in the TW Area
A leaking radiator or central heating pipe might start as a small drip, but it rarely stays that way. Water escaping from a pressurised system can soak floorboards, damage ceilings below, corrode nearby pipework, and cause your boiler to lose pressure and shut down — leaving you without heat or hot water. Acting quickly limits the damage and the cost.
Common Causes We Deal With
- Corroded or split radiator panels — older steel radiators are particularly prone, especially if the system water has not been treated with inhibitor
- Leaking radiator valves — thermostatic radiator valves (TRVs) and lockshield valves can weep at the gland or body joint
- Loose or failed pipe joints — compression and push-fit fittings behind walls or under floors can work loose over time
- Pinhole leaks in pipework — caused by internal corrosion, often linked to untreated or contaminated system water
- Leaking system components — pump seals, motorised valve bodies, and manifold connections on underfloor heating circuits
What We Do
Our engineers carry the tools and materials to diagnose and fix most heating leaks in a single visit. That includes isolating individual radiators, replacing valves, re-making pipe joints, and repairing or replacing damaged radiator sections. Where a leak is hidden — inside a wall or beneath a floor — we use non-invasive leak detection methods to pinpoint it before any unnecessary opening up of the structure.
After the repair we check system pressure, bleed the circuit if needed, and advise on adding or topping up corrosion inhibitor to help prevent future leaks.
Why Not Leave It Until Morning?
Central heating systems run at pressure. Even a slow drip can drop that pressure enough to trigger a boiler lockout overnight. More seriously, water finding its way into a ceiling void or timber subfloor can cause structural damage and mould growth within days. If the leak is near an electrical fitting, it becomes a safety issue too.

Marc has been fantastic, I can't recommend him enough. He responded exceptionally quickly to our plea for help when our boiler stopped working. No hot water with kids = nightmare. He offered an appointment the following day and arrived when he said he would.
