Signs of a Drain or Waste Pipe Leak
Drain and waste pipe leaks can go unnoticed for long periods, often leading to structural damage or health hazards. Here are some common warning signs:
- Unpleasant odours: Bad smells around sinks, toilets, or external drains may suggest a leak in the waste system.
- Slow drainage: If water is draining slowly, it could be due to a partial blockage or a leak within the pipework.
- Damp patches or water stains: Wastewater leaks can cause discoloration or damp spots on walls, ceilings, or floors.
- Mould or mildew: Excess moisture from waste leaks can lead to fungal growth and musty smells.
- Subsidence or cracked flooring: In more serious cases, underground waste leaks can cause ground movement.
- Rodent or insect activity: Leaking drains can attract pests, especially in basements and crawl spaces.
Advanced Technology for Drain & Waste Leak Detection
We use industry-leading equipment to locate drain and waste pipe leaks quickly and with minimal disruption:
CCTV drain camera inspections
Tracer gas testing
Smoke generator
Dye testing
Thermal imaging
Borescope inspections
Pressure testing
These advanced tools help us detect leaks behind walls, under floors, and underground—so we can find the issue without unnecessary guesswork or damage.
Full-Service Drain Leak Investigation & Reporting
After we detect the leak, we can provide expert advice and even carry out repairs if required. Alternatively, if you already have a plumber or drainage specialist on site, we can simply deliver a detection-only service.
We also assist with home insurance claims, providing full written reports to support your Trace and Access claim (also known as “Track and Trace”) where applicable.
