Complete Radiator Installation & Repair Services
We supply and fit all types of domestic radiators, from standard steel panel units to heavy cast iron models suited to older period properties. When we fit a new radiator in an East Lothian home, we calculate the exact British Thermal Unit requirement for the specific room size and window layout. This ensures the unit actually heats the space rather than just getting hot itself. We also repair existing setups, swapping out seized lockshield valves, replacing faulty thermostatic radiator valves, and fixing pinhole leaks that cause sudden boiler pressure drops.
Call us when your rooms struggle to reach a comfortable temperature or if you spot rust patches and damp spots under your valves. Old, sludged up or undersized radiators force your boiler to work much harder than necessary, driving up your daily gas bills. Upgrading a failing radiator or fixing a persistent leak protects your flooring from long term water damage and restores proper heat circulation throughout your property.
A leaking valve often needs leak detection first, and a persistently cold radiator can point to a boiler fault.

What Radiator Installation & Repair Covers
-
Radiator installation and replacement
We remove old, inefficient units and mount modern, high output radiators. We adjust the copper pipework to fit the new dimensions and ensure secure wall fixings. If you have internal stud walls, we locate the timber supports to guarantee the new radiator stays firmly attached to the wall.
-
Heated towel rail fitting
We install towel rails in bathrooms and wet rooms. We often advise customers on dual fuel options, allowing you to dry towels using an electric element during the summer when the main central heating system is switched off.
-
Cast iron and designer radiators
Heavy column and cast iron radiators require heavy duty brackets and sometimes dedicated floor supports. We regularly fit these in larger rural cottages and traditional coastal homes across East Lothian to match the period aesthetic while providing excellent heat retention.
-
Adding or moving a radiator
If you are extending a room or changing a layout, we can lift floorboards, extend your existing pipework, and relocate the radiator to a more effective position. We ensure the new pipe runs are fully insulated and securely clipped beneath the floor.
-
Thermostatic radiator valve (TRV) replacement
We swap out manual or broken valves for new TRVs. This gives you individual temperature control in each room, cutting down on wasted heat in empty bedrooms and helping your boiler run much more efficiently.
-
Radiator balancing
We adjust the lockshield valves across your entire property to ensure hot water flows evenly. This stops the radiator nearest the boiler from hogging all the heat while the furthest ones stay completely lukewarm.

Common Radiator Problems We Solve
-
My Radiator Is Not Heating
A radiator can stay cold because of trapped air, a stuck TRV pin, a closed lockshield valve or restricted flow. We check the controls and temperature pattern first, then identify the fault without replacing working parts unnecessarily.
-
My Radiator or Valve Is Leaking
Leaks commonly appear at valve glands, compression joints, threaded tails or radiator plugs. We locate the exact source because water can track along a pipe and drip away from the faulty joint. We then tighten, reseal or replace the affected component as required.
-
My Radiator Is Cold at the Top
A cold upper section usually indicates trapped air. We bleed the radiator, check that water fills it correctly and inspect for recurring symptoms. If air returns repeatedly, we advise on the next appropriate check rather than treating repeated bleeding as a permanent repair.
-
My Radiator Is Rusting or Making Noise
Rust around seams or lower edges can lead to a pinhole leak, particularly where moisture or coastal air has affected the finish. Knocking and ticking can come from valves, pipe movement or incorrect adjustment. We inspect the symptom and explain whether repair, balancing or replacement makes sense.

How We Handle Your Radiator Installation & Repair
-
1. Inspect and Confirm the Work
After initial contact, we inspect the radiator, valves, wall and visible connections. For a new or replacement radiator, we measure the available space and check pipe centres. For a fault, we reproduce or trace the symptom before recommending work.
-
2. Explain the Options
We explain whether the radiator needs adjustment, a valve repair, replacement or relocation. You have one point of contact for the work, including any supply-and-install requirements. We quote per job once we understand the radiator type, access and parts needed.
-
3. Complete the Installation or Repair
We protect the immediate work area, isolate and drain what the job requires, then carry out the agreed work. We fit brackets and valves securely, make the connections and refill the affected section carefully while checking each disturbed joint.
-
4. Test and Hand Over
We vent the radiator, test for leaks and confirm that it warms and responds to its controls. Where the work affects heat distribution, we balance the relevant radiators. We leave the area tidy and explain how to use the valves and what to monitor afterwards.
Radiator Installation & Repair Questions
-
We quote each job individually because the cost depends on the radiator type, size, valves, pipe positions and access. Moving pipes or fitting a heavy column radiator involves different work from replacing a like-for-like panel radiator. Our quote sets out the agreed supply-and-install work before we begin.
-
We recommend using a plumber because radiator fitting involves draining, secure mounting, valve connections, refilling and leak testing. A poorly made connection can damage floors or ceilings. We also check whether the existing valves and pipe positions suit the new radiator before fitting it.
-
We usually repair a leak when it comes from a serviceable valve, joint, plug or radiator tail. If corrosion has caused a pinhole in the radiator body, replacement often makes more sense because another weak area may fail later. We inspect the source before advising you.
-
We commonly find leaks at valve glands, compression joints and threaded radiator tails. Corrosion can also affect radiator seams and lower edges. Because water travels along metalwork, we dry and inspect the fittings carefully to identify the actual source before carrying out a repair.
-
We take bookings from 7am to 7pm, seven days a week. Availability depends on existing appointments, the urgency of the leak and whether we need to obtain a particular radiator or valve. We confirm the expected appointment arrangements when you contact us.
-
We consider the room dimensions, external walls, windows, insulation and available wall space. Large rural rooms and older cottages can need more output than a small modern room. We recommend a suitable radiator type and size after checking the property rather than judging by appearance alone.
-
We often see corrosion develop around chipped finishes, seams and lower radiator edges in coastal homes. Wiping away moisture and checking early rust spots can help. Once corrosion penetrates the metal or causes a pinhole leak, we normally advise replacement instead of a temporary patch.
