Expert Ceiling Leak Detection That Saves Properties from Serious Damage
Is water dripping from your ceiling, but no one can find the cause?
You’re not alone. One of our recent cases involved a leaking ceiling that multiple professionals failed to fix. What seemed like small plumbing problems turned out to be a hidden ceiling leak causing serious water damage, hidden within the building’s structure.
At MML Plumbing, we specialise in non-invasive leak detection for hidden water leaks, leaking pipes, and even roof leaks. We combine advanced tools like thermal imaging, moisture leak detection, and borescope inspection to detect the exact spot of the leak, without unnecessary damage or guesswork.
The Situation: Water Dripping from the Ceiling – No One Could Find It
A concerned flat owner contacted us after weeks of water stains on the bedroom ceiling. Several plumbers had checked the sink, shower, and toilet, but no one could identify the source.
Signs of Trouble:
- Persistent damp smell and mould growth which you have to investigate immediately
- Discoloured patches on the ceiling directly above the bedroom
- Previous advice failed to fix the leak
The property was at risk of structural damage, and the water appeared to be travelling through insulation and cavities from a tiny leak in the bathroom above.

What we did step by step-by-step leak detection process
1. Full Leak Investigation Using Non-Invasive Methods
We started with:
- Thermal imaging to trace hidden heat signatures
- Moisture readings to identify the water path
- Borescopic camera inspection inside the walls and ceiling
- Dye testing of the plumbing system, including bath, shower, sink, and toilet
2. Tracing the Water Flow
Despite multiple inspections by other professionals, no one had followed the water flow from the source to the lowest point where the dripping occurred.
The last plumber broke the tiles above the toilet and underneath the washing machine, but he did not find the leak.
Our technology and our plumbing experience allowed us to pinpoint the exact spot where a broken pipe behind the toilet was leaking water down through the floor into the ceiling below.
3. Final Diagnosis
- Primary issue: A cracked concealed toilet cistern and a failed toilet overflow
- Secondary issue: A failed seal around the toilet’s waste connection
- Result: A steady trickle of water was seeping behind the toilet cistern, with no visible signs above
This led to gradual damp build-up, damaging insulation and causing water stains on the ceiling below.
Repair and Restoration Plan
Once the leaking pipe was found, we recommended a permanent solution:
- Isolate and repair the damaged section of the toilet cistern
- Reinstate all damaged plasterboard in the ceiling and floor
- Dry out the affected insulation and structure
- Re-tile and return the property to its original condition
All findings were documented with images, suitable for insurance claims and landlord reporting.
Why This Matters
Failing to address small leaks quickly can result in:
- Costly repairs
- Irreversible roof damage
- Long-term mould growth
- Structural damage to your building
Leaks are often caused by:
- Minor cracks in pipes
- Poor sealing around showers, sinks, or toilets
- Wet weather combined with poor ventilation
- Issues with the main water supply
Our team will find leaks that others miss—and we do it without tearing your home apart.
How to Tell If You Have a Ceiling Leak
If you’ve noticed:
- Water dripping from your ceiling
- Small brown or yellow stains
- Damp patches or bubbling paint
- A musty or damp smell
- Water is pooling in the lowest point of the room
You likely have a leaking ceiling. Act now to prevent further damage.
