Where leaks hide and how they get found
Leaks inside walls
Warning signs
- Stains or bubbling paint
- Soft drywall near a bathroom or kitchen
- Musty odor or baseboards pulling away
The fix
Moisture meters and thermal cameras trace the wet area to the pipe, fitting, or drain behind the wall, so only a small section is opened.
Ceiling leaks
Warning signs
- Brown rings on the ceiling
- Dripping from light fixtures
- Stains below a bathroom or AC unit
The fix
The pro checks upstairs plumbing, attic lines, roof penetrations, and evaporative cooler or AC lines, then isolates the source.
Yard and main line leaks
Warning signs
- Green or soggy patch in a desert yard
- Sinkhole or wet soil near the meter
- Low pressure throughout the house
The fix
The main line between the meter and house is pressure tested and located acoustically, then repaired or replaced.
Irrigation and pool leaks
Warning signs
- Drip system zones always wet
- Pool losing more than evaporation
- Water at the street after the system runs
The fix
Zones are tested one at a time. Pool leaks are checked with dye and pressure tests on the lines and shell.
Why leak detection matters in Tucson
In Tucson's dry air, a leak inside a wall can run for weeks before a stain shows. Hard water pits copper lines, and ground movement from expansive clay can crack main lines and yard pipes. Homes in areas like Midtown (85716), the Eastside (85710, 85730), Oro Valley (85737), and Green Valley (85614) built from the 1970s to the 1990s are especially prone as their original plumbing ages.

Frequently Asked Questions
How much does leak detection cost in Tucson?
A standard leak detection visit commonly runs about $150 to $500. Larger homes, multiple suspected leaks, or pool and yard lines can cost more. Ask for the price up front.
Who is responsible for a leak between the meter and my house?
In most cases the homeowner is responsible for the line from the meter to the house. The water utility is usually responsible for the meter and the line on the street side. Check with your water provider to confirm.
How can I check for a leak myself?
Turn off every faucet, toilet, appliance, and irrigation zone, then watch the leak indicator on your water meter for 15 minutes. If it moves, water is going somewhere.
Can you find a leak without opening walls?
Usually the leak can be pinpointed with acoustic and thermal tools first, so only a small, targeted opening is needed for the repair.
What if the leak is under my slab?
See our slab leak detection page. Slab leaks are common in Tucson because of shifting clay soil, hard water, and aging copper.
