Radiator Repair & Installation in Glasgow
Radiators fail politely — a cold bottom here, a weeping valve there — and then a February morning finds three rooms cold. Our Glasgow engineers repair, replace and add radiators with prices fixed before the visit.
Repairs: cold spots, leaks and valves
Most radiator problems in Glasgow resolve in one visit: bleeding and re-pressurising for air-bound radiators, valve gland repairs for the classic slow drip, TRV head or pin replacements for radiators stuck cold or stuck hot, and tail re-seals where the connection weeps. Panels pinholed by internal corrosion are replaced rather than patched — a pinhole means the steel is finished, and the interesting question becomes whether the system water that caused it is treated or still eating the rest.
Replacement and upgrades
Upgrading radiators is where comfort per pound is highest: the classic move is single panels to doubles in the coldest rooms, with new thermostatic valves fitted as standard. Every replacement includes fresh valves, a clean connection, re-dosing the system inhibitor and re-balancing so the new radiator doesn't steal flow from its neighbours. Old radiators are removed and disposed of; the price agreed at booking is per-radiator and all-in.
Sludge: the underlying story
Black magnetite sludge is what happens when system water goes untreated: steel radiator interiors corrode, the debris settles in radiator bottoms and low pipe runs, and eventually pumps, valves and boiler heat exchangers suffer. Cold-bottomed radiators across a Glasgow house are the visible symptom. The proper response scales with severity — from dosing inhibitor, through single-radiator flushes, to a full system powerflush — and our powerflush page covers when each is honestly justified.
Pricing
Radiator work prices cleanly because the scope is knowable: from £85 for valve and TRV work, fixed per-radiator prices for swaps agreed at booking, and surveyed quotes for moves and additions. The only honest variable is what the system water reveals — if the engineer finds sludge or dead inhibitor, you'll get a separate recommendation and price for treating it, not a padded radiator bill.
Coverage for radiator repair & installation runs right across Glasgow — Ibrox, Springburn and Hyndland included — plus the surrounding Greater Glasgow area. Jobs route by proximity rather than by a call centre's guess at the map, which is why local engineers arrive with the right parts more often than not.
Frequently asked questions
Can you move a radiator to another wall?
Yes — it's routine, priced after a quick look at the pipe route. Under-floor access makes it cheap; solid floors or finished rooms make it dearer. The engineer will tell you honestly if the route makes it poor value.
My radiator valve is leaking — is that urgent?
It's urgent-ish: a slow gland leak wets carpet and drops boiler pressure but rarely floods. Put a container under it, top up the boiler pressure if needed, and book promptly. A valve spraying rather than weeping is a call-now situation — isolate both radiator valves and phone.
Why is my radiator cold at the bottom?
Sludge — corrosion debris settled inside the panel, blocking circulation across the bottom. One radiator can be removed and flushed; several cold-bottomed radiators suggest the system needs cleansing and inhibitor, possibly a powerflush. Bleeding won't help; that's for cold tops.
Why is my radiator cold at the top?
Trapped air. Bleeding the radiator releases it — a minute's job with a bleed key, then re-check the boiler pressure and top up via the filling loop if it's dropped. If the same radiator needs bleeding every few weeks, air is getting in or being generated somewhere, and that's worth diagnosing.
