My underfloor heating isn’t getting warm enough. Can you find the problem?

Yes. Poor heating can be caused by several things, including controls, circulation, valves, pipework or the heating system itself. We’ll check the system, find the likely cause and explain what needs to be done before carrying out the repair.

Do I need to replace the whole underfloor heating system if there’s a problem?

Usually not. Many underfloor heating faults can be repaired without replacing the entire system. We’ll inspect it first and tell you honestly whether a repair is enough or whether part of the system needs upgrading or replacing.

Can you give me an approximate price before starting?

Yes. Once we understand the system and the problem, we’ll give you an idea of the expected cost before starting wherever possible. If something unexpected is found during the work, we’ll speak to you before doing anything extra.

Are your underfloor heating prices higher than other companies?

We always try to keep our pricing fair and competitive. Our Google reviews also include customers who mention fair pricing, reliability and the quality of our workmanship. We prefer to be clear about costs rather than leave you with unexpected charges at the end. googlereviewsjimi

Can you repair an underfloor heating system that someone else installed?

Yes. It doesn’t need to have been installed by JM Plumbing. If the system is suitable to work on, we can inspect it, diagnose the fault and advise you on the best way to fix it.

Can you repair just one area or room that isn’t heating properly?

Yes. If only one room or section isn’t heating correctly, we can investigate that part of the system rather than assuming the whole system has a problem.

Can you service and maintain an existing underfloor heating system?

Yes. Regular checks and maintenance can help identify issues with controls, circulation and system performance before they turn into bigger problems.

Can you install underfloor heating as part of a renovation?

Yes. If you’re renovating a property, bathroom or other part of your home, we can discuss the underfloor heating requirements and how the system can be incorporated into the project.
