Central Heating Repairs · Dumbarton & West Dunbartonshire, Helensburgh and Loch Lomond

Radiators cold, boiler fine? That's a heating-system job, and it's ours.

Half the house warm and the other half freezing, radiators that need bleeding every week, a pump that groans, a thermostat that lies. Central heating faults sit outside the boiler and need an engineer who understands the whole system. We fix pumps, valves, thermostats, radiators and sludge, and we power-flush when the water tells us to.

  • Cold radiators, cold spots and rooms that never warm up diagnosed on the first visit
  • Pumps, motorised valves, thermostats and programmers replaced at a fixed price
  • Power flushing and magnetic filters for sludged-up systems
  • Radiator moves, additions and replacements, including designer and towel rails
  • Smart thermostats fitted and set up on your phone before we leave
  • System and regular boilers, cylinders and loft tanks all covered

How we work

What you can expect on the day

  • We test the whole system, not just the boiler, so the real fault gets fixed.
  • A water sample tells us whether a flush will cure cold radiators or whether it is a valve.
  • We balance the radiators before we leave so the far rooms warm up too.
  • Elderly, disabled or vulnerable customers go to the front of the queue. Tell us on the phone and we'll move things around.

Questions

Central Heating Repairs questions we get asked

My boiler works but the radiators stay cold. What is wrong?

Usually one of four things: air in the system, a stuck motorised valve, a tired pump, or sludge in the pipework. We check all four on the first visit and quote the fix before we touch anything.

How much does a power flush cost?

It is a fixed price per radiator count, agreed on the phone. We only recommend it when a water sample shows the system needs it, and we fit a magnetic filter afterwards so it stays clean.

Can you move a radiator or add one in an extension?

Yes. We size the new radiator for the room, run the pipework neatly and rebalance the system. Towel rails and designer radiators are no problem.

“Boiler died on a Tuesday morning. Phoned at nine, price by half nine, new boiler running by teatime. Nothing added on the day. Can't fault them.”

“Two other firms told me I needed a new boiler. Sure Point fixed it for the cost of a part and told me it had a few years left in it. Honest lads.”

David R. · ClydebankBoiler Repair · Google

“Converted our old system to a combi. Big old house, lots of pipework, and they still finished in the day and left it spotless.”
