The service
What leak detection is, what a visit covers and where the line is.
The short answer
Leak detection finds where water is escaping from a supply line, drain, fixture or underground pipe before the damage spreads. Leak Detection in Palo Alto is booked through pros who cover its 6 ZIP codes, in neighborhoods such as Old Palo Alto, Crescent Park, and Professorville. In Palo Alto, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. Each pro names a price, and the choice is yours.
If leak detection is an emergency
A running leak can soak drywall, flooring and insulation in a short time. Stop the water first, then bring in a pro to locate the source.
Treat it as urgent if
- Water is dripping from a ceiling or through a light fixture
- The water meter is spinning with every fixture off
- A wall is bulging, stained or soft to the touch
- You hear running water but nothing is in use
What a leak detection visit includes
What is included depends on the jobs you pick and on how each pro sets up their visit and timing. You see the exact scope with each pro's price before you book.
- Leak diagnosis
- Moisture/pressure testing
- Findings report
- Your pro’s own workmanship warranty

What shapes a leak detection job
These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.
What you receive from a leak search
A good search ends with clear findings you can act on. Each pro sets what they provide, and the booking shows what is included.
- The location of the leak marked on the floor, wall or yard, with photos
- Which system is leaking: hot supply, cold supply, drain or buried line
- The meter and pressure readings that confirmed the leak
- Moisture or thermal images that show the extent of the wet area
- Observations on possible causes, such as a failed fitting, pinhole or frozen split
- A recommended repair and who should do it, licensed where required
- Written notes you can share with your insurer
What is not part of leak detection
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Opening walls or floors to repair what is found, once the total reaches $1,000 in labor and materials, goes to a licensed contractor.
- Repair or replacement of leaking pipe unless the pro offers it, and re-piping is licensed plumbing work.
- Water extraction, drying and mold cleanup, see Water Damage Restoration and Mold Remediation.
- Roof leaks and window leaks, see Roofing Inspection and Roof Repair.
- Swimming pool leaks, see Pool Leak Detection.
- In Palo Alto, city of Palo Alto requires permits for structural and electrical work. NorTech's handyman scope stays under the exemption threshold.

Before you book leak detection
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Do a quick meter test first
Turn off every fixture and appliance, then watch the meter dial or low-flow indicator for a few minutes. A moving indicator confirms a leak, and the reading helps the pro scope the visit.
Locate the main shut-off
Make sure the main valve turns. A valve that is stuck or leaking is better known before the pro arrives.
Photograph stains and damp areas
Take pictures of discoloration, bubbling paint, soft floors and wet carpet edges, with a date. It helps the pro trace the path and supports an insurance claim.
Listen at quiet times
Stand quietly near the suspected area at night when the house is silent and listen for hissing or dripping. Tell the pro what you hear and where.
Note when it started
A change in the bill, a sudden damp spot or a recent plumbing job all narrow the search. Share the date and what you noticed first.
Ask what is included
Ask each pro whether the visit includes opening a small access, marking the leak and giving written findings, and whether they also do the repair.
