Slab Leak Detection & Repair

Our Services

Slab Leak Services Across Arizona

We handle the full slab leak job: find the leak, match the fix to what we found, and carry out the repair. If your floor feels warm in one place, the meter moves with all water off, or a bill jumped for no clear reason, start with the signs and detection behind the job, then pick the service below that fits your situation.

Not sure which service fits your leak? Call us and describe what you see.

Every job starts the same way, with a meter check and detection that narrows the leak to one place. What happens after that depends on the line, the floor above it, and how many times the line has leaked. The five services below cover the situations we see most often: a single leak in a sound line, a line that keeps failing, a leak in a business or multi-unit building, a leak check before a purchase closes, and a home with no leak yet that needs a simple watch routine.

ServiceWhat it fixesWhen it fitsWhat you get

Reroute and repipingA line that keeps leaking.A line that keeps leaking, or a spot fix that will not hold.Work in walls and the attic, with the slab left closed.
Commercial detectionLeaks in offices, shops, and multi-unit buildings.A leak in a business or multi-unit building.A written findings report for the owner or manager.
Pre-purchase inspectionA hidden leak in a home you are buying.You are buying and want to know before closing.A written report to take to your agent.
PreventionNo leak yet — a routine that catches one early.No signs, and you want to keep it that way.A few minutes a month, done by you.

How to read this table: match the first column to what you see at home, then read across. If two rows both sound right, the third column is the one that decides. A single leak in a sound line takes a spot repair; a line that has leaked before, or tests weak along its length, takes a reroute.

Slab Leak Spot Repair

We open a small area of slab at the leak, replace the damaged section of line, and patch the slab back. This is the fix for a single leak in a line that is otherwise sound. Slab leak spot repair

Water-Line Reroute and Repiping

We run a new line through walls or the attic and cap the old line under the slab, so the leaking section carries no water at all. This is the fix when a line keeps leaking or a spot fix will not hold. Water-line reroute and repiping

Commercial Leak Detection

We locate leaks in offices, retail spaces, restaurants, warehouses, and apartment buildings, working around business hours, tenants, and phased schedules. Detection is planned so the building keeps running, and the visit ends with written findings you can hand to an owner, an insurer, or a repair crew. Commercial leak detection

Pre-Purchase Leak Inspection

We check a home for hidden slab leaks before closing, then hand you a report that shows what we checked, what we found, and what to ask the seller. It is a check for buyers who want to know what they are walking into. Pre-purchase leak inspection

Slab Leak Prevention

For homes with no leak yet, we lay out a simple routine: pressure awareness, meter checks, watching the bill, and a seasonal walk through the home. Small habits catch a leak early, while it is still small. Slab leak prevention

Not sure which service fits? Call us at (480) 681-1950 and describe what you see. We will point you to the right page, or set up a visit if the signs point to an active leak. You can also start from the homepage, which walks through signs, detection, and all the repair options in one place.

How Every Job Runs, Step by Step

Every job starts the same way, with a meter check and detection that narrows the leak to one place. What happens after that depends on the line, the floor above it, and how many times the line has leaked.

  1. 1

    Meter check

    All water off, then watch the dial.

  2. 2

    Detection

    Listening gear, thermal imaging, pressure testing, moisture readings.

  3. 3

    Match the fix

    Spot repair, reroute, or a planned visit, matched to what we found.

  4. 4

    Repair

    The fix that fits, then patching back.

Detection comes first and decides everything: we do not cut concrete until listening gear, thermal imaging, pressure testing, and moisture readings agree on one place. Once the spot is marked, the work moves quickly from opening the slab to patching it back.

Matching the Service to What You See

Match what is happening at your home or building to the service built for it. A warm floor and a moving meter point to detection and repair, a line that has leaked before points to a reroute, a leak in a business points to commercial detection, a home you are about to buy points to a pre-purchase inspection, and a home with no signs at all points to the prevention routine. The list beside the photo walks through each situation in turn.

Frequently Asked Questions

A slab leak is a leak in a water line that runs under or through the concrete slab beneath a home or building. Because the line sits out of sight, the leak can run for a while before it shows as a warm floor, a damp patch, or a bill that climbs without a change in use.

If you see signs of an active leak in your home, start with detection and then the fix that fits, which is usually spot repair or a reroute. If the building is commercial, pick commercial detection. If you are buying, pick the pre-purchase inspection. If nothing leaks yet, pick prevention.

We serve homes and buildings across Arizona, including Phoenix, Tucson, Mesa, Gilbert, Chandler, Scottsdale, Tempe, and Flagstaff. Our base sits in Tempe, and we travel across the state for homes and commercial buildings alike. If your town sits outside that list, call us and we will tell you whether we can reach you.

Call us at (480) 681-1950 and describe what you see. We will set up a visit, run a meter check, and locate the leak before any repair work starts. For a home you are buying, ask for the pre-purchase inspection instead.
