Common Questions — Radiator Repair in Harrow

Why is my radiator leaking in Harrow?

Radiator leaks in Harrow are most commonly at the valve tail (where the valve joins the radiator) or at the bleed nipple. Both can usually be fixed without draining the whole system — we carry all common radiator valve sizes.

Can you add a radiator to a room in Harrow?

Yes. We can extend your heating circuit to an additional room in Harrow — connecting from the nearest flow and return pipes and fitting a new TRV. We'll check your boiler capacity can support the additional load before quoting.

My radiator is cold at the bottom but warm at the top in Harrow. What does that mean?

A radiator that's warm at the top but cold at the bottom in a Harrow property almost always has sludge settled at the base. We can flush that radiator individually or recommend a full power flush if multiple radiators show the same symptoms.
