boiler repairs in Watton-at-Stone: questions we get a lot
How often should I need to top up?▾
A healthy sealed system should hold pressure for 6-12 months between top-ups. Anything more frequent points to a leak.
Could it be the expansion vessel?▾
Yes — a perished expansion vessel inside the boiler is a common cause. We test the vessel as part of diagnosis.
Is it worth repairing an old boiler?▾
Honest answer: if it's over 12 years old and the repair is more than £400, replacement usually makes more financial sense. We'll lay out both options without pressure.
Do you charge a callout fee?▾
We charge a clear diagnostic fee (told to you upfront before we attend). It covers proper on-site diagnosis. The repair itself is then quoted as a fixed price you agree before any work starts.
