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 Windham 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.
How Do You Find a Hidden Leak?
Not every leak announces itself with a puddle. Hidden leaks show up as an unexplained jump in your water bill, the sound of running water when everything is off, a water meter that keeps spinning with all fixtures closed, musty odors, warm spots on a floor, or stains spreading across a ceiling or wall. Our plumbers trace leaks methodically — isolating sections of the supply system, checking fixture connections and shutoffs, and inspecting the most common failure points — so we open only what actually needs to be opened. The person diagnosing your leak is not working against a sales quota. If the fix is an inexpensive fill valve, that is what we will tell you. Our goal on a first visit is simple: solve the problem cleanly and become the plumber you call next time.

What are the signs of a hidden water leak?
A higher-than-normal water bill, the sound of running water when fixtures are off, a spinning water meter with everything closed, musty smells, damp or warm spots on floors, and stains on ceilings or walls are all common signs of a hidden leak. If you notice any of these, have it checked promptly — leaks only get worse.
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.
