Radiator Repair Near Me — Cold Spots, Leaks & Replacements.
From a simple bleed and balance to a full radiator replacement, we fix every radiator issue in every property type across Norfolk.
Cold at the top — bleeding required
Air trapped in your radiator rises to the top and creates a cold band. We bleed the system and check for the underlying cause — often a leak elsewhere introducing air.
Cold at the bottom — sludge build-up
Black sludge (magnetite) settles at the base of radiators and prevents hot water circulation. We power-flush the system and fit a magnetic filter to prevent return.
Leaking radiators and valves
Pinhole leaks, weeping valves, and leaking joints are all common. We isolate, repair, or replace the faulty component with minimal disruption.
Radiator replacement and upgrade
Old flat-panel radiators can be replaced with more efficient double-panel or designer units without major pipework changes. We advise on BTU output for your room size.
Why is my radiator cold at the bottom?
Almost always sludge — magnetite (black iron oxide) from corroding pipes. It settles at the base and blocks circulation. A power flush solves it permanently if a magnetic filter is also fitted.
Can I replace just one radiator?
Yes. We can replace a single radiator in a few hours. We bring the new unit, make the pipework connections, balance the valve, and test heat output before leaving.
How much does radiator repair cost?
Bleeding and balancing: £60–£100. Valve replacement: £80–£150. Full radiator replacement (supply and fit): £200–£500 depending on size and style.
Should I get a power flush?
If multiple radiators are cold at the bottom, or your system is slow to heat up, a power flush is cost-effective. We'll advise honestly after inspection.
