Boiler Repair Marshalswick

Fast, Honest Boiler Repairs From Just Down the Road

When the boiler stops, distance matters. Marshalswick is one of the closest areas to our Lemsford Road base, and our aim is to find the real cause on the first visit, fix it there and then where we can, and tell you honestly if a boiler is not worth repairing.

On combis, no hot water with working heating is often the diverter valve, and hot water that runs hot and cold is often limescale in the heat exchanger. On the older system and regular boilers common in Marshalswick and Jersey Farm, the fault is often a pump, motorised valve or cylinder thermostat rather than the boiler itself.

In a cold snap, the most common call is a frozen condensate pipe. If a repair would cost a large share of a new boiler, we will say so and give you both options, including boiler installation in Marshalswick.

Common Boiler Faults We Fix in Marshalswick

These are the repairs we carry out most often in Marshalswick and Jersey Farm homes. We test before replacing anything, so you are not paying for parts that were never the problem.

Low or Falling Pressure: Usually a leak, a passing pressure relief valve or an expansion vessel that needs recharging or replacing.
No Hot Water on a Combi: Often a diverter valve or a plate heat exchanger blocked with limescale from hard water.
No Heating or No Hot Water on a System Boiler: Frequently a failed pump, a stuck motorised valve or a faulty cylinder thermostat.
Ignition Faults and Lockouts: A boiler that tries to light and then locks out, often caused by worn electrodes, a gas supply issue or a blocked condensate pipe.
Noisy Boilers: Banging or kettling sounds usually mean scale or sludge in the heat exchanger restricting the flow of water.

Signs Your Boiler Needs Repairing

If you notice any of these, call us before a small fault turns into a full breakdown.

A Fault Code or Lockout

The boiler has stopped and shows an error on the display. Note the code before you call, as it helps us bring the right parts.

No Heating or Hot Water

One or both have stopped working, even though the boiler appears to have power.

Pressure Below 1 Bar

The pressure gauge keeps dropping and the boiler needs topping up more and more often.

Unusual Noises or Leaks

Banging, whistling or gurgling, or water dripping from under the boiler.

 Trustindex verifies that the original source of the review is Google. Really happy with the work carried out by Alban Plumbing and Heating. They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house.
The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work.
I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come.  His 5 star status is well deserved.

Boiler Repair Marshalswick: Your Questions

Why do I have heating but no hot water?

On a combi boiler, the most common cause is a faulty diverter valve, or a plate heat exchanger blocked with limescale. On a system or regular boiler, it is often a motorised valve that has stuck, or a faulty cylinder thermostat. We test each part to find which one it is.

Why does my boiler pressure keep dropping?

Usually because water is escaping somewhere: a small leak on a radiator or pipe, a pressure relief valve that is letting by, or an expansion vessel that has lost its air charge and is pushing water out through the relief valve. Topping up only treats the symptom, so it is worth having it checked.

How do I thaw a frozen condensate pipe?

Find the plastic pipe that runs from the boiler to a drain outside, and pour warm, not boiling, water along it, or hold a hot water bottle against it. Once it has thawed, reset the boiler. If it freezes regularly, we can reroute or insulate it.

How quickly can you get to Marshalswick?

It depends on our bookings that day, but Marshalswick is one of the closest areas to our base in St Albans. We give you an honest arrival time when you call.

How much does a boiler repair cost?

It depends on the fault and the parts needed. We diagnose the problem first, then tell you the price of the repair before doing it, so you can decide.

Is my old boiler worth repairing?

It depends on its age, the fault, whether parts are still available and what the repair would cost compared with a new boiler. We give you both options and an honest recommendation.
