Leak Detection

Leak Detection

Not every leak is visible. Some happen behind walls, under floors, or in slab foundations. Leak detection is the process of narrowing down where water is coming from so the right repair can be planned.

Leak Detection — frequently asked

What are common signs of a hidden leak?+

Higher water bills, damp or warm spots, musty odors, low pressure at one fixture, or the sound of water when nothing is running.

Why might the source of a leak need assessment?+

Water travels along the path of least resistance, so the visible damp spot is often not where the leak actually is. Locating the true source avoids unnecessary opening of walls or floors.
