COMMON PROBLEMS

Radiator Problems We Fix in Wandsworth

From a single cold radiator to a whole house that never quite heats evenly, we diagnose the actual cause rather than just papering over the symptom.

Cold at the Top

Usually trapped air — a quick bleed restores full heat, common after a system’s been off over summer.

Cold at the Bottom

Often sludge build-up restricting flow — common in older Sanderstead and Thornton Heath systems that haven’t been power flushed in years.

Leaking Radiator or Valve

A worn valve or corroded joint can develop a slow drip that’s easy to miss until it causes damage.

Uneven Heat Across Rooms

Common in larger Purley and Coulsdon homes — a system that’s out of balance heats some rooms while others stay cool.

FAQs

Radiator Services in Wandsworth — Questions Answered

This is usually trapped air, which rises to the top of the radiator and blocks hot water from reaching it. Bleeding the radiator releases the trapped air and is normally a quick, low-cost fix.
This pattern usually points to sludge or debris settling at the bottom of the radiator, restricting water flow. A power flush clears the build-up and restores full, even heat.

A bleed and basic diagnosis starts from £69, a valve or leak repair from £99, and power flushing or replacement work from £280 depending on the number of radiators involved. All prices are fixed and agreed before work starts.

Power flushing forces water through your heating system at high velocity to clear out sludge and debris. It's typically needed if several radiators are cold at the bottom, your boiler is noisy, or your system hasn't been flushed in several years.

Yes. We cover the entire Wandsworth borough — Battersea, Balham, Putney, Tooting and Wandsworth Town / Southfields — postcodes SW11, SW12, SW15, SW17 and SW18.

Yes. If some rooms are consistently too hot and others too cold, we can rebalance the flow across your whole system so every radiator heats evenly.
