Leak Detection

A hidden leak inside a wall, under a slab, or behind a fixture can cause serious damage long before it's visible. NorTech connects you with a vetted local provider to find it early, using real diagnostic tools rather than guesswork, with findings delivered in a written report.

Leak detection across the Bay Area

Rising water bills, a musty smell, or a soft spot in flooring are often the first hints of a leak that's already been running for a while behind a wall or under a slab. NorTech connects you with a background-checked provider who uses moisture and pressure testing to pinpoint the source without unnecessary demolition, then delivers a findings report you can act on.

Why early detection saves money

A slab or wall leak that runs undetected for months can cause structural damage, mold growth, and ruined flooring — costs far beyond the leak repair itself. Catching it early through proper diagnostic testing, rather than waiting for visible damage, is what keeps a plumbing problem from becoming a much larger renovation.

Reading your water bill for early warning signs

A sudden, unexplained jump in your water bill is often the earliest and cheapest signal of a hidden leak, well before any visible sign shows up in the home. Comparing bills month to month is a simple habit that can catch a leak long before it causes real damage.

When to book leak detection

Your water bill has jumped with no obvious explanation

You notice a musty smell or unexplained moisture without a visible source

A wall, ceiling, or floor shows discoloration or softness

You want to check for leaks before or after a major plumbing project

A previous leak was repaired but you want to confirm no others exist

30-Day Warranty

Backed by your provider’s warranty. If covered work fails, your provider makes it right — free.

Looking for a licensed plumber? Bigger jobs and anything that needs a permit go to a verified California C-36 contractor. See licensed plumber services.
