Frequently asked questions — boiler repairs, Bishop's Stortford
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.
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.
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.
