- Valve and TRV replacement
- Radiator replacement and upgrades

Common radiator services situations
- One radiator cold, several radiators slow to heat, leaking valves or cold spots at the bottom.
- Old radiators that need replacement because of corrosion, poor heat output or room changes.
- Heating balance issues after extensions, boiler changes or radiator upgrades.
How All Hours handles the callout
- We ask which radiators are affected and whether the issue is one room or the whole system.
- The engineer checks valves, balancing, trapped air, sludge symptoms and pipework.
- Minor issues can often be resolved quickly; replacement or flushing is discussed only where justified.
- Work is completed tidily with attention to floors, walls and finished rooms.
When to call now
Call now if the problem is causing active water damage, leaving the property without heating or hot water, stopping the only usable toilet, or creating a fault that cannot safely wait. For boiler and heating issues, note the make, model and fault code if you can see them without opening the case.
What can usually happen on the first visit
The engineer checks valves, trapped air, balancing, circulation and visible pipework before recommending replacement or larger heating-system work.
What may need follow-up
Designer radiator swaps, pipework alterations and flushing recommendations depend on wall strength, pipe routes, system condition and heat output.
Safe first steps before you call
- Check whether the issue is one radiator, upstairs/downstairs, or the whole heating system.
- Do not force stuck valves or bleed radiators if the boiler pressure is already low and you are not confident repressurising.
- Send photos of valves, pipe entry points, corrosion and any cold-spot pattern if visible.
What this problem is often confused with
- A cold radiator can be air, valve failure, balancing, sludge, pipework restriction, pump issue or system design.
- A leaking valve may expose older pipework or seized fittings once disturbed.
- Cold spots do not automatically mean a full power flush is the right answer.
When this may need a different next step
- Large system redesigns, heat-loss calculations or decorative making-good may need a planned quote rather than an emergency-style visit.
What to tell us before arrival
- Check whether one radiator or the whole system is affected.
- Do not force seized valves.
- Send photos of the radiator, valves and surrounding floor/wall condition.

Direct answers about radiator services
Quick answers to common questions before you call.
Why is only one radiator cold?
It may be trapped air, a stuck valve, balancing issue or local blockage. The pattern helps diagnose the cause.
Can you replace a radiator with a designer radiator?
Yes, where pipework, wall fixing and heat output are suitable.
Do cold spots mean I need a power flush?
Not always. Cold spots can indicate sludge, but the system should be assessed before recommending a flush.
