Client Location – Belfast, Northern Ireland
The Problem
A homeowner in Belfast contacted B Keenan Heating and Plumbing after noticing a persistent damp smell in their kitchen. While there were no obvious visible leaks or standing water, the odour was becoming increasingly noticeable and concerning.
Damp smells are often an early warning sign of hidden water issues, so the client requested professional leak detection to investigate the source before it developed into a larger problem.
Leak Detection Investigation
We carried out a detailed leak detection inspection of the kitchen area, starting with all visible pipework, appliances, and drainage points. With no immediate issues found, we focused on concealed pipework and waste connections where smells and minor leaks can often originate.
Using a structured and methodical leak detection approach, we traced the source of the damp smell to pipework located beneath the kitchen area.


The Cause: Damaged Waste Pipe
Our investigation revealed that a waste pipe had been chewed through—most likely by rats or mice. This damage allowed wastewater to escape slowly, causing damp conditions and the unpleasant smell within the kitchen.
Because the leak was from a waste pipe and not under pressure, it did not create obvious signs like dripping or pooling water, making it harder to identify without proper leak detection.
The Solution
Once the issue was identified, we removed the damaged section of waste pipe and replaced it with a secure, fully sealed connection. All surrounding pipework was checked to ensure there were no additional weak points or damage.
Final leak detection checks were carried out to confirm that the leak had been fully resolved and that no further water or odour issues remained.
The Outcome
- Hidden leak successfully detected in kitchen waste pipe
- Damaged section replaced and system sealed
- Damp smell completely eliminated
- Kitchen environment restored to normal
The client was relieved to have the issue resolved quickly, especially as the source of the smell had been unclear.
Key Takeaway: Damp Smells Can Indicate Hidden Leaks
A persistent damp smell—particularly in kitchens or bathrooms—can often be a sign of a hidden leak, even when no water is visible. Professional leak detection ensures these issues are found and fixed before they lead to further damage.
