How a Pipe Leak Happens

  2. Shutoff valve — closing it stops flow to the leak
  3. Pinhole leak — sprays fast under pressure
  4. Water damage — spreads quickly once a line fails

Leak Detection & Repair for South Portland Homes

Quick response matters with leaks. Water damage gets worse by the hour and can lead to mold, structural damage, and costly repairs. Contact us as soon as you notice a leak and we will get it handled.

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.
