Frozen condensate in Welwyn Village? Boiler repairs sorted properly
If your boiler in Welwyn Village stopped working in cold weather and is showing a fault code, the condensate pipe outside has likely frozen. We can talk you through thawing it on the phone, or come out and lag it properly so it doesn't happen again. Most Welwyn Village repair callouts we diagnose and fix on the first visit — common parts (PRVs, diverters, pumps, PCBs) live on the van.

Why Welwyn Village customers pick us for boiler repairs
We've been doing boiler repairs in Hertford long enough to know which streets have shared chimneys, which estates have undersized gas supplies, and which boilers tend to fail first.
That experience means we get the spec right at the survey, not halfway through the install.
And we don't cut corners on the bits you can't see — proper pipework, magnetic filter, full system flush where needed.

Things Welwyn Village 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.
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 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.
