Frozen condensate in Chelmsford? Boiler repairs sorted properly

We can talk you through thawing it on the phone, or come out and lag it properly so it doesn't happen again.

Things Chelmsford customers usually ask about boiler repairs
How do I thaw it myself?▾
Pour warm (not boiling) water along the external condensate pipe, especially at any low points or bends. Then reset the boiler. We'll happily walk you through it on the phone.
How do I stop it freezing again?▾
We can re-route the condensate to drain internally, fit a wider-bore external section, or lag the existing pipe properly. The right fix depends on your install.
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.
