Frequently asked questions
Before you book
Why is one radiator not heating properly?
Air, a stuck or faulty valve, system balance, restricted circulation or another heating-system issue may be responsible. Diagnosis should consider the symptoms across the system.
Can a leaking radiator valve be repaired?
Some valve leaks can be resolved by adjustment or replacing a component. Other cases require valve replacement, depending on condition and access.
Can you replace a radiator with a different size?
Yes, subject to wall space, pipework and the heat requirement of the room. The proposed radiator should be sized appropriately rather than selected by appearance alone.
Will the floor and surrounding area be protected?
Yes. Appropriate protection is used and the work area is treated carefully throughout the visit.
Does a cold radiator always need replacing?
No. Many cold-radiator problems are caused by valves, air, balance or circulation and may be repairable without replacing the radiator.
