Leak Detection in Santa Fe, NM
Hidden leaks here hide in adobe, under saltillo, and in crawl spaces you cannot stand in. A jumping water meter with every fixture off is the first tell; a warm stripe on a slab or a musty casita is the second. We use acoustic listening and thermal imaging to mark a spot before we open finish that a Historic District house cannot easily replace. 505-316-4231.

Why “open the wall and look” is the wrong first move
In frame construction you can miss by a stud and still patch. In 20-inch adobe you miss by a foot and you have a masonry project. We narrow the zone first. Slab leaks get isolation tests on the hot and cold so we do not jackhammer the wrong room.
Bills, stains, and the well that will not stop
City customers see the meter. Well customers see a pump that never sleeps. Either way, a leak you cannot see is cheaper to find than to live with. We are not a restoration company — we find it and fix the pipe. Flooring after the fact is your call or your insurer’s.
Find it before anyone opens the wall
Adobe and Territorial walls in Santa Fe are 18 to 24 inches. A “small exploratory hole” is a plaster project. We listen, we use thermal imaging where the finish allows, and we isolate branches by shutting valves until the meter stops. The city meter is the honest witness on a municipal supply: if every fixture is off and the triangle is still spinning, water is leaving the system. On a well, the pressure tank and the pump are the witness. We do not start cutting because a wall feels cool. Cool is not a location.
Slab, wall, and the leak that is the heater
A hot spot on a slab can be a hot-water line, a radiant loop, or a heater pan that has been overflowing into a crack. Those are three different repairs. A stain on a ceiling under a bath is often the tub shoe or the toilet seal, not a pressurized line in the joist. We check the easy failures first because they are common and because opening a ceiling for a wax ring is a bad trade. If the pressurized line is the one, we mark it, we tell you the finish risk, and we cut once.
What we hand you for insurance
If a supply line has damaged finishes, the documentation is photos, the location, the cause if we can see it, and the repair we performed to stop it. We do not write a novel for an adjuster and we do not invent a cause. “Pipe failed” is acceptable when that is all the metal shows. “Installed wrong in 1998” is something we say only when the installation is visibly wrong. You can hand the notes to whoever is paying. We are not a public adjuster.
Pinholes, pressure, and the second leak
Copper pinholes in a hard-water house rarely travel alone. If we repair one and the rest of that branch is paper-thin, we will say the branch should be replaced, not chased pinhole by pinhole for a year. High pressure makes this worse. A pressure reducing valve that has failed open will eat a house. We check static pressure while we are there. If it is north of 80 psi, the leak repair without a PRV is a short story. Expansion on a closed system does the same thing to relief valves and supply lines.
When detection is the whole visit
Sometimes the visit is the location and a price, and the repair is a different day because the access needs a carpenter or because you want a second thought before we open a historic wall. That is a finished visit, not a failure. You leave with a mark, a photo, and a number. If the leak is active and damaging the house, we repair it in the same trip when the parts are on the truck. We stock the common stops, supplies, and PEX transitions. We do not stock every oddball valve from 1962, and we will not pretend we do.
The first half hour
Meter or pump first. If the meter is still with every fixture off, we have a leak on your side of it. We shut branches until it stops, which is a location even before a camera or a microphone comes out. Hot versus cold matters. A hot leak and a cold leak are different pipes and often different eras of the house. We ask what changed: a freeze, a pressure spike, a remodel, a new softener that was tied in with a pinhole waiting to happen. Then we listen and we look at temperature. Adobe lies. A cool wall can be mass, not water. We do not cut it for being cool.
The repair that follows the mark
Once the spot is marked, the quote is the pipe, the access, and the finish. Opening plaster in a historic room is more money than opening drywall in a 1998 addition, and we price it that way instead of using one “leak repair” number for both. If the leak is in a slab, we talk about the loop or the line, the flooring, and whether an overhead refeed is smarter than a trench through saltillo. Overhead is often smarter. It is not a failure of detection. It is a choice to stop digging up a floor that costs more than the pipe. You make that choice with the number in front of you.
After the water is back
We watch the meter again. A repair that does not stop the triangle is not done, even if the wet spot we found is dry. Second leaks happen in pinholed copper. We would rather find the second one while the tools are out than get a call on Friday. Pressure gets checked. If you are over 80 psi we talk about a reducing valve before we leave, because the next pinhole is already scheduled by the pressure. Photos of the open wall are yours if you want them for the painter or the insurer.
What a detection visit costs versus what a hole costs
Finding a leak is its own work. The price is for the time, the isolation, and the mark, whether or not we repair it the same day. Repairing it is the second price, and it depends on access. People get angry when those two are mixed into one number that changes in the driveway. We keep them separate so you can stop after the mark and call a remodeler, or you can tell us to open the wall. A detection that ends in “we cannot hear it, here is the next test” is still a result. It is not a free visit. Slab leaks in particular can take longer than a ceiling stain from a tub shoe, and the fee should reflect that once we know which one we are in. We will tell you early if the day is turning into a slab. Insurance clients should know we document; we do not argue with the carrier. Bring the claim number if you have one. If you do not, the photos and the notes still stand. Hard water and high pressure stay in the conversation because a repaired pinhole next to five more pinholes is not a favor. We would rather sell you a branch replacement once than a detection every quarter.
Bring the meter reading if you have one
If you watched the city meter move with every faucet off, tell us how fast. A slow spin and a fast spin are different leaks, and the fast one is the ceiling you should already have shut the main for. On a well, the symptom is the pump short-cycling or running when nobody is using water. Either fact saves the first twenty minutes. We still verify it ourselves. A neighbor’s irrigation on your line has fooled people, and we would rather rule that out than open a wall for a hose bib you forgot.
What we actually get called for
Not a generic list — these are the failures this climate and housing stock produce.
Meter moves with everything off
Supply-side leak. We isolate house versus irrigation.
Warm floor, no radiant on
Hot-side slab leak until proven otherwise.
Stain that returns after paint
Roof is possible; so is a supply in the wall above. We rule out plumbing before you recarpet.
Musty crawl after winter
A split that thawed and is still weeping.
How a job runs
Confirm it is plumbing
Meter, dye, or pressure-down test.
Locate
Acoustic, thermal, or camera as the house allows.
Open small, repair, verify
Then the meter should sit still.
Questions people ask before they call
How do I know I have a hidden leak?
Meter movement, a pump that short-cycles, a hot streak on a slab, the sound of water with all taps closed, or a bill that jumped with no extra people in the house.
Do you guarantee the location?
We mark the best location the tools and access allow. Adobe and post-tension slabs have limits. If we cannot get a clean mark we say so before we swing.
Can you find irrigation leaks too?
Yes, on the house side of the backflow. City-side or ditch-company issues are not our repair.
