Radiator Repair in Greater Vancouver
A radiator that stays cold, leaks, or makes strange noises is usually pointing to a problem somewhere in your hydronic heating system rather than the radiator itself. Gold Star Plumbing and Heating offers radiator repair, installation, and maintenance across Metro Vancouver, including Burnaby, Coquitlam, Port Coquitlam, Port Moody, and the North Shore. We diagnose the actual cause of the problem so the repair holds, rather than just addressing the symptom.
Radiator repair is one of the services included in our full range of heating services.
Common Radiator Problems

The most common radiator complaints we see are units that stay cold at the top while warm at the bottom, radiators that do not heat at all, leaking valves or fittings, and banging or gurgling noises coming from the pipework. Each of these points to a slightly different underlying cause, which is why an accurate diagnosis matters before any repair begins.
Common complaints include:
Why Radiators Need Bleeding
A radiator that is cold at the top but warm at the bottom usually has trapped air inside, which prevents hot water from filling the whole unit. Bleeding the radiator releases the trapped air and allows it to heat evenly again. If a radiator keeps needing to be bled repeatedly, that is often a sign of a bigger issue elsewhere in the system rather than a one time fix.
Radiator Repair Versus Replacement
Most radiator problems, including leaks, stuck valves, and airlocks, can be repaired without replacing the entire unit. Radiators that have significant internal corrosion or have been leaking for a long time may be better candidates for replacement, especially if repeated repairs have not solved the underlying issue. We give you an honest recommendation based on the actual condition of the unit.

Radiator Installation

If you are adding a radiator to a room that has never had one, or upgrading an old, undersized unit, we size and install a new radiator that connects properly to your existing hydronic system. Correct sizing matters here, since an undersized radiator will struggle to heat a room even if everything else in the system is working fine. We take room size, insulation, and window area into account when recommending a replacement, rather than simply matching whatever size was there before.
Radiator Maintenance
Periodic bleeding, checking valves for smooth operation, and balancing the system so heat is distributed evenly across all radiators helps prevent many of the common problems homeowners run into. A quick maintenance check as part of a broader heating service visit can catch small radiator issues before they turn into a bigger repair. We can include a radiator check as part of a full boiler maintenance visit, or handle it as a standalone service if your boiler is otherwise running fine.
Key maintenance tasks include:
Balancing a Multi Radiator System
In homes with several radiators, one room can end up too warm while another stays cold, even when every radiator seems to be working on its own. This usually means the system needs balancing, which involves adjusting valves throughout the home so hot water flows evenly to every radiator rather than favouring the ones closest to the boiler. Balancing is often overlooked, but it can make a real difference in comfort without requiring any new equipment, and it is worth checking any time you notice uneven heat across rooms.
