Quick answers on boiler repairs in Stansted Mountfitchet
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.
Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
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.
