How a Pipe Leak Happens
- Supply line — pressurized water inside the wall
- Shutoff valve — closing it stops flow to the leak
- Pinhole leak — sprays fast under pressure
- Water damage — spreads quickly once a line fails
Leak Detection & Repair for Yarmouth Homes
Whether it is a dripping faucet, a leaking pipe under the sink, a toilet that will not stop running, or a more serious water line issue, we locate the source of the problem accurately and make a lasting repair. If your leak involves a failing water heater, we can diagnose and address that too.
What About Frozen and Burst Pipes in Cold Weather?
Burst pipes are the most damaging leak a home can have — a single split supply line can release hundreds of gallons in an hour. Pipes in exterior walls, crawl spaces, garages, and unheated basements are the usual victims when temperatures drop below zero. If a pipe bursts, shut off the main water valve immediately (usually near the water meter or where the line enters the house), open faucets to relieve pressure, and call us. After the repair, we will show you what caused the failure and what prevents the next one — pipe insulation, rerouting vulnerable runs, or heat tape where appropriate. Homes heated primarily by heat pumps or with reduced-temperature zones are especially worth a freeze-risk check.

- Most of Yarmouth is on Yarmouth Water District water, drawn from aquifer wells in North Yarmouth; the pipes, valves and fixtures inside the house are the part we look after.

Leak Detection & Repair in Yarmouth, ME FAQs

Why did my water bill suddenly spike?
A sudden spike is most often a running toilet, which can silently waste a surprising amount of water each day, or a hidden supply-line leak. An easy first check: put food coloring in the toilet tank and see if it appears in the bowl without flushing. If the toilet checks out, call a plumber to trace the leak.
What should I do first if a pipe bursts?
Shut off your main water valve right away — it is usually located where the water line enters your home or near the meter. Then open faucets to drain pressure from the lines, move belongings away from the water, and call a plumber. The faster the water is off, the less damage you will have.
