Client Location – Cranley, Bangor, County Down
The Problem
A homeowner in Bangor contacted B Keenan Heating and Plumbing after noticing signs of damp and an unpleasant smell within their property. The issue was intermittent at first but gradually became more noticeable, raising concerns about a potential hidden leak.
With no obvious source visible, the client requested professional leak detection to identify the problem before it caused further damage.
Leak Detection Investigation
We carried out a detailed leak detection assessment, starting with all visible pipework and drainage systems within the property. Given the nature of the smell and damp, we focused on waste and soil pipe systems, which are common sources of hidden leaks.
Using a structured and methodical leak detection approach, we traced the issue to the soil stack within the property.


The Cause: Leaking Soil Stack
Our investigation revealed that the soil stack had developed a leak, allowing wastewater to escape. This was the source of both the damp conditions and the unpleasant odour experienced by the client.
Because soil stack leaks are not always under pressure, they can go unnoticed for some time, making professional leak detection essential for accurate diagnosis.
The Solution
Once the leak was identified, we carried out the necessary repairs to the soil stack, ensuring all connections were properly sealed and secure. The repair was completed efficiently to minimise disruption to the property.
Following the repair, we conducted final leak detection checks to confirm the issue had been fully resolved and that no further leaks were present.
The Outcome
- Leak successfully detected in soil stack
- Damaged section repaired and sealed
- Damp and odour issues resolved
- Property restored to a clean, safe condition
The client was relieved to have the issue clearly diagnosed and resolved quickly.
Key Takeaway: Soil Stack Leaks Can Cause Hidden Damp and Odours
Leaks in soil stacks are a common but often overlooked cause of damp and unpleasant smells in a property. Professional leak detection ensures these issues are accurately located and fixed before they worsen.
