Frequently asked questions — boiler repairs, Little Dunmow
Why has my heating stopped working?▾
Top causes: frozen condensate pipe in cold weather, low system pressure, a seized pump after summer dormancy, or a stuck motorised valve. Most are quick fixes once diagnosed properly.
Can I do anything before you arrive?▾
Check the boiler pressure (should be 1.0-1.5 bar cold). If it's below 0.5, top up using the filling loop. If you can hear the boiler firing but radiators stay cold, the issue is in the system, not the boiler itself.
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.
