From concern to repair

Slab leak service for Gilbert homes

Water appearing around flooring may be the first indication of a problem beneath a concrete slab. Trident Plumbing & Drain provides slab leak detection and repair in Gilbert. We investigate the concern, explain what was found and discuss the work before starting.

Arrange service through our North Phoenix office. Describe the current symptoms and any previous inspection or repair, even if you are unsure which pipe is involved. The assessment should establish the plumbing problem before decisions about the repair are made.

Bring the observations

Know the warning signs of a slab leak

Unexpected water use, warm or damp flooring, lower pressure and running-water sounds when fixtures are off can signal a hidden plumbing concern. Cracks, musty odors or unexplained moisture also deserve attention. These signs are reasons to investigate, not a diagnosis of the pipe or foundation.

Make a note of when the change began and which areas are affected. Explain whether moisture is actively spreading or whether the concern comes and goes. That pattern, together with the inspection findings, gives the team a better starting point than guessing where to open a floor.

Establish the problem

Our slab leak repair process

The process starts with leak detection using specialized equipment and an assessment of the affected water line. The purpose is to connect the symptoms to the damaged plumbing and identify the repair it needs. Trident then explains the findings and available options.

Ask what the assessment established about the line and what still needs checking. If you have records from earlier leak work, provide them before the repair discussion. A clear explanation should distinguish the confirmed problem from assumptions based only on a floor stain or water bill.

Agree on the work

Understand the repair before it begins

Repair planning should address the damaged pipe, its location and the access needed to reach or work around it. Review the proposed plumbing work with the technician and ask how the recommendation follows from the detection results.

Discuss which areas of the home need access and what the repair includes. If work around flooring or other materials needs separate attention, clarify that responsibility. The plan should give you a practical picture of the plumbing work and how to prepare the affected space for the visit.

Check and document

Testing, cleanup and the next conversation

Trident includes testing and cleanup in its slab leak repair process. Ask the technician to explain the work completed and how the repaired plumbing was checked. Keep that explanation with any service records for the home.

If moisture, sound or pressure concerns remain, describe them to the team and discuss the next assessment. A plumbing repair and the condition of surrounding materials are separate parts of understanding the property. Report active or spreading water promptly so the office knows the situation has changed.

Early warnings

How Gilbert's usage alerts can flag a leak

Because a supply line under the floor leaks day and night, the Town may notice it before you do. Its staff email customers whose use jumps sharply from the previous month, and the Town contacts anyone whose use stays at 20 gallons per hour or more for 36 consecutive hours. Its 2025 water quality report says every meter is read monthly. Treat one of those notices as a reason to check for a hidden leak, not just a bill to dispute.

The Town also offers free water efficiency checkups aimed at helping residents detect leaks early, and a six-part video series that starts with reading your meter. Those steps can confirm water is moving when everything is off. Pinpointing a leak under concrete takes detection equipment, and the repair depends on where the line runs. Tell us what the Town's notice or checkup showed, so the search starts from that evidence.

Repair budget

Factors in a slab leak repair estimate

Slab leak estimates vary with where the leak sits and how the line can be reached or replaced. These items shape the number.

For a reroute or other larger repair, you can finance through the GreenSky® Credit Program. Call your insurance company before work starts to ask what the policy covers.

  • How precisely the leak can be located before anything is opened.
  • A spot repair through the floor or rerouting the line through walls or the attic.
  • Flooring that has to come up and be replaced afterward.
  • Whether the leak is on a hot or cold line, and the pipe material.
  • Testing the repaired line before the area is closed up.

Under the slab

Signals of a hidden leak in a Gilbert home

A pressurized line under the floor keeps leaking whether or not anything is running, and the Town's usage monitoring can notice.

Nonstop use that triggers a Town alert
36 hours

A leak under pressure keeps water moving through the meter around the clock. The Town reaches out when use holds at 20 gallons an hour or more for 36 straight hours.

Typical pressure in the Town's water system
50–80 psi

The Town's system typically delivers 50 to 80 psi. Pressure at the house well above that range adds strain on lines in and under the slab.

Answers before you book

Questions about
slab leak repair in Gilbert.

Questions about slab leak repair in Gilbert? Start here, or tell us what is happening at your home.

Ask our team
Can a higher water bill identify the leak location?

No. Unexpected water use is one clue. Detection and inspection are needed to establish whether a line is leaking and where the problem is.

Will you explain the repair before starting?

Yes. Trident discusses the findings and repair options before work begins. Ask about the affected pipe, planned access and any work outside the plumbing scope.

What happens after the pipe repair?

The service includes testing and cleanup. Ask what was checked and keep a record of the repaired area and any recommended follow-up.

Should I share details of a previous slab leak?

Yes. Previous inspection findings and repair notes help explain the history of the plumbing. Share what was repaired and whether the current symptoms are new or recurring.

The Town says my water use is continuous. Could it be a slab leak?

It could be one cause. The Town flags use of 20 gallons per hour or more for 36 consecutive hours and lists pool filling, irrigation changes, more people in the home and running toilets among other reasons use rises. Rule those out, then have the home checked for a hidden leak.

Does the Town of Gilbert help find leaks?

It offers free water efficiency checkups to help residents detect leaks early, plus a six-part video series on checking the meter, pool, irrigation, service line, indoor fixtures and water treatment equipment. Locating and repairing a leak under concrete is private plumbing work.
