Radiator valve replacement
Leaking, seized or ancient radiator valves swapped for new — including thermostatic (TRV) upgrades.
About this job
A weeping valve or a TRV that's stuck open or closed makes rooms uncomfortable and wastes energy. We drain down only what's needed, swap the valves, and refit with fresh olives and PTFE so they seal first time. Upgrading to thermostatic valves lets you set each room's temperature independently — one of the cheapest comfort upgrades going.
What's included
- ✔Partial drain-down of the heating circuit
- ✔New TRV or manual valves supplied and fitted
- ✔Fresh olives and seals for a first-time seal
- ✔System refilled, bled and balanced
- ✔Check for leaks under full system pressure
