Find Hidden Leaks Before They Cause Damage

Leak detection and pipe repair services in San Antonio, Texas

Your water bill in San Antonio has doubled without explanation, or you notice damp spots on the ceiling, warped flooring, or mold growing along the baseboards. These signs point to a hidden leak inside a wall, under a slab, or in a crawl space where you cannot see the water escaping. Even a small pinhole leak can release hundreds of gallons over weeks, soaking insulation, rotting wood framing, and creating conditions for mold growth. B & C Service Pros, LLC locates leaks quickly in San Antonio properties and repairs the damaged section of pipe before the problem spreads.

We use electronic leak detection equipment to pinpoint the exact location of a leak without tearing out large sections of drywall or cutting into multiple areas. Once we find the source, we cut out the damaged pipe, install a new section, and secure it with fittings that meet local plumbing codes. You will see your water pressure return to normal, no more wet spots forming, and your water bill drop back to expected levels.

What Leak Detection and Pipe Repair Looks Like

We begin by shutting off all water fixtures in your San Antonio home and checking the water meter to see if it continues to move, which confirms a leak somewhere in the system. If the meter stays active, we use acoustic sensors and moisture meters to trace the sound or wetness back to the source. In slab leaks, we listen for water running beneath the foundation and use thermal imaging to detect temperature changes caused by escaping water.

Once we locate the leak, you will see the wet area dry out completely within days, and you will no longer hear the faint sound of running water when all faucets are turned off. Your water pressure will stabilize, and you will stop seeing unexplained puddles or stains on walls and ceilings.

The repair itself involves cutting into drywall or flooring to access the damaged pipe, removing the corroded or cracked section, and installing a new length of copper, PEX, or galvanized pipe depending on what is already in place. We test the repair under pressure to confirm there are no additional weak points, then patch and repaint the access area. We do not repair leaks in sections of pipe that show extensive corrosion or multiple pinhole leaks, since the rest of the line is likely to fail soon after.

Common concerns before starting leak detection

Homeowners often ask how much damage a leak can cause, whether detection requires cutting into walls, and how quickly repairs can be completed. Here are the most common questions we hear.

How do I know if I have a hidden leak?
You may notice an unexplained increase in your water bill, hear water running when all fixtures are off, or see damp spots, discoloration, or mold on walls, ceilings, or floors. A water meter that continues to spin with all taps closed confirms a leak somewhere in the system.
How do you find a leak without tearing up my house?
We use electronic listening devices, moisture sensors, and thermal imaging cameras to locate leaks inside walls, under slabs, and in crawl spaces without invasive demolition. Once we identify the exact spot, we make a small access point to repair the pipe and minimize disruption.
What happens if I ignore a small leak in San Antonio?
Even a minor leak can release thousands of gallons over months, saturating insulation, rotting wood studs, and creating mold growth that spreads through walls and ceilings. Slab leaks can undermine the foundation and cause floors to crack or shift over time.
How long does a typical pipe repair take?
Most repairs take two to four hours once we locate the leak, depending on how accessible the pipe is and whether we need to cut into drywall, flooring, or a slab. Slab leaks may require rerouting the line through walls or ceilings if the foundation cannot be easily accessed.
Will you fix the drywall and paint after the repair?
We patch the drywall and apply a base coat of paint to match the surrounding area as closely as possible. For larger repairs or textured walls, you may want to hire a finish carpenter or painter to blend the patch perfectly with the rest of the room.
