Common Plumbing Problems We Solve
No job too small. No problem too tricky. Serving St. Thomas and London homes and businesses daily.
Leaky Faucets & Pipes
A dripping faucet wastes thousands of litres of water yearly. We diagnose and fix leaks at the source — fast and permanently.
Running Toilets
A constantly running toilet can waste 200+ litres per day. Faulty flappers, fill valves, and flush handles are our bread and butter.
Low Water Pressure
We trace pressure problems to their source — blocked aerators, failing regulators, corroded pipes, or supply line issues.
Pipe Repairs
Cracked, leaking, or corroded pipe joints and connections repaired or replaced before they cause water damage.
Shutoff Valve Service
Seizing or leaking shutoff valves under sinks and behind toilets replaced with quality ball valves that last.
Hidden Leak Detection
Unexplained water bills or damp patches? We locate hidden leaks in walls and floors with non-invasive techniques.
