Slab Leak Detection & Repair in Los Lunas, NM
Tell us what you're seeing. You get a straight answer on the phone and a local slab leak technician on the way.
Chapter 1
Sound familiar?
A leak under a concrete slab hides well. It can run for weeks under tile or carpet before a warm patch, a creeping meter or an odd bill gives it away.
No single sign proves a slab leak. Two or more together is a good reason to pick up the phone.
Chapter 2
While the technician is on the way
A few safe steps can slow the damage and give the technician a head start. Anything beyond these is a job for the pro.
Describe the problem and we'll dispatchSmell gas? Leave the home and call the gas utility and 911 from outside.
- 01Run the meter test. Turn off every faucet, the dishwasher, washer, ice maker and irrigation, then watch the meter for a few minutes. Any movement means water is going somewhere.
- 02Slow a hot-side leak. If the clues point to hot water, closing the cold supply valve on the water heater can slow it. Leave the gas and electrical controls alone.
- 03Close the main if water surfaces. Water pooling on the floor or seeping through grout calls for the main shut-off.
- 04Take photos. Wet spots, damaged flooring and the meter reading. Dated pictures help the technician and keep a record for you.
- 05Leave the floor in one piece. Pulling up tile or cutting concrete to hunt for the leak usually means a bigger hole in the wrong place.

Slab leaks across Los Lunas: every area is different
Los Lunas grew in layers, and the age of a house says a lot about what's under its floor. The 87031 area, home to about 44,000 people, runs from the old core near the river out to newer streets and open acreage. A slab leak call looks different in each.
Around the Village Center, many homes are older adobe-style and territorial houses, and foundations vary. Some sit on slabs and some don't, and the plumbing may have been added to or changed over decades. A technician here starts by working out how water actually reaches each fixture.
The 1970s–1990s streets of East Los Lunas are classic slab country. Copper supply lines often run beneath the concrete, and years of very hard water and ground that shifts with the seasons put stress on them. Most slab leak calls in Los Lunas come from homes like these.
Across the river, the planned neighbourhoods of West Los Lunas went up mostly from the 2000s on, often plumbed with PEX. Leaks there tend to show up at fittings, or where caliche and clay move beneath the slab.
Manufactured homes and many houses on larger lots aren't built on slabs at all. If yours sits on piers or over a crawlspace, an under-floor leak is found a different way, and we'll tell you that on the phone instead of sending the wrong specialist.

Slab leak help in Los Lunas, start to finish
Seven things people call about, each with its own page. Browse every service.
Slab leak detection
Pinpointing the leak before anyone opens a floor. Technicians use acoustic listening, thermal imaging and pressure testing to narrow the spot and tell the hot side from the cold.
How detection works →Slab leak repair
A targeted opening through the slab at the leak, a repair to the line, a pressure test, then the concrete patched. Finished flooring is restored separately by flooring pros.
About spot repair →Pipe rerouting
Abandon the failing under-slab line and run a new one through walls or the attic, so a later leak on that run doesn't mean another hole in your floor.
When to reroute →Whole-home repipe
When leaks keep coming back, replacing the supply lines throughout the house and moving them overhead can make more sense than chasing one spot at a time.
Repiping a slab home →Hot water slab leaks
Warm tile, a dog that won't leave one spot, a water heater that never rests. Hot-side leaks have their own clues and their own repair choices.
Hot-side clues →Signs of a slab leak
Meter, bill, sound, floor and foundation clues, plus the common look-alikes, such as a running toilet, worth ruling out before you call.
Check the signs →Insurance questions
What to ask your insurer, how to document what you've found and how the technician's written findings can support that conversation. Coverage decisions belong to your insurer.

Slab leak questions from Los Lunas callers
Not seeing yours? Ask it on the phone.
Call before it gets worse →A slab leak is a leak in a water supply line that runs beneath a home's concrete foundation slab. Because the pipe sits under concrete and flooring, you usually can't see the leak itself. You see its side effects instead: a warm floor, a meter that won't stop, a high bill or damp flooring. Drain and sewer lines can run under slabs too, but those are a different job, and if that's your issue we'll point you toward a drain specialist.
An independent local plumbing professional who handles slab leak detection and repair. We don't do the work ourselves. We're a referral service: we take your call, ask a few questions and connect you with a technician serving Los Lunas. They explain what they find and give you pricing before starting anything, and the decision about what happens next stays with you.
Yes. We take calls from across ZIP code 87031, which includes the Village of Los Lunas and the surrounding unincorporated parts of Valencia County. If you're just beyond that, call anyway. We'll tell you plainly whether a technician can reach your address before anyone schedules a visit.
You can. Most manufactured homes aren't built on a concrete slab, so a leak under the floor is located and repaired in a different way. Tell us how your home is set up when you call. We'll be straight with you about whether it's a slab job and help you find the right kind of help either way.
Yes. Plenty of callers aren't sure. Describe what you've noticed and we'll ask about the meter, the floor and the water heater. If it sounds like something simpler, such as a worn toilet flapper or a dripping outdoor spigot, we'll say so, and you may be able to save yourself a visit.
Not as a first step. The technician's first job is to locate the leak as precisely as possible before anything is opened. Once it's found, you talk through the options together: a targeted opening at the leak, rerouting the line through walls or the attic, or a larger repipe if leaks keep repeating in the same house.
That depends on where the leak is, how it's reached and which repair you choose, so we won't guess at a number over the phone. What we can describe is the process. The technician explains your options and gives upfront pricing before any work begins, with no hidden fees added afterward.
Calls are answered 24/7, including nights, weekends and holidays. Dispatch depends on which technicians are available, and same-day or emergency visits are offered where available. If water is actively surfacing, close your main shut-off first and tell us right away so the call is treated as urgent.
Your address, roughly when the house was built if you know, and what you've noticed: where the floor is warm or wet, whether the meter moves with everything off, and whether the water heater runs more than usual. Photos help later on, but you don't need anything special to start the conversation.
Water under the slab keeps running until someone finds it.
