boiler repairs in Allens Green: questions we get a lot
Is it dangerous to keep topping up?▾
Not immediately — but the cause needs finding. Repeated top-ups mean fresh oxygenated water keeps entering the system, which corrodes radiators and pumps from the inside.
Where do hidden leaks usually hide?▾
Pressure relief valve discharging outside, perished pump seals, pinhole leaks at radiator valves, or a failing expansion vessel. Each one has a different fix.
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.
Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
