Common questions about boiler repairs in Little Dunmow
Where do boiler leaks usually come from?▾
Most common: pressure relief valve discharging because system pressure is too high, a perished pump seal, or a failing heat exchanger on older units. We diagnose properly rather than guess.
Should I turn the boiler off?▾
If water is actively dripping and you can see it pooling, yes — switch the boiler off at the spur, and turn the system pressure down via the filling loop if you can. Then call us.
How fast can you come out?▾
We aim for same-day on no-heat and no-hot-water situations. Tell us when you call if anyone elderly or with young children is in the property — we prioritise.
Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
