The cost to find a leak on an underfloor heating system starts from £595 plus vat.

The actual water leak detection cost will depend on the type of underfloor heating system, the size of the system and your location.

Usually underfloor heating leaks are covered by insurance under trace and access. Most home insurance companies have a trace and access section but it is not always included as standard.

These microorganisms produce a distinct musty odor that can be unpleasant. Additionally, if the leaking water comes into contact with sewage or other contaminants, it can cause a foul smell.

Yes, leaks in underfloor heating can be repaired. The method of repair will depend on the location of the leak and the type of underfloor heating system.

In some cases, the leak may be easily accessible and can be fixed by tightening a loose connection or replacing a damaged pipe.

In other cases, a repair may require more extensive work such as lifting the flooring to access the pipes.

Our professional plumbers and heating engineers are able identify and fix the leak efficiently.

Underfloor heating leaks can be prevented with proactive maintenance and testing including:

Regular maintenance:

Conduct regular inspections and maintenance of the underfloor heating system to identify potential issues before they become leaks. This includes checking for signs of wear and tear, loose connections, and damaged pipes.

Pressure testing:

Before the system is commissioned, perform a pressure test to ensure there are no leaks. This involves pressurizing the system with air or water and checking for any drop in pressure, which indicates a leak.

Pipe protection:

Use pipe protection sleeves or insulation where pipes pass through walls or concrete slabs to prevent any damage that could lead to leaks.

Use quality materials:

Invest in high-quality pipes and fittings that are designed for underfloor heating systems. Cheaper or substandard materials may be more prone to leaks and failures.

Avoid sharp bends or kinks:

Ensure pipes are laid out without sharp bends or kinks, as these can cause stress and potential leaks over time.

Avoid excessive pressure:

Avoid over-pressurizing the system, as it can strain the pipes and fittings, leading to leaks. Follow the recommended pressure limits provided by the manufacturer.

Proper flooring installation:

When installing the flooring over the underfloor heating system, ensure it is done correctly to avoid damaging the pipes. Avoid excessive force or sharp objects that can puncture or damage the pipes.
