Undetected leaks cause microbial growth, structural damage, and skyrocketing water bills. O5 Plumbing finds and fixes leaks fast with upfront pricing and same-day service when available.
Hidden leaks are the most destructive plumbing problem a homeowner can face not because a single drop of water is dangerous, but because slow leaks go unnoticed for weeks or months. Water finds every gap, every void, every material that absorbs it. By the time you see water damage, the damage behind the walls is already extensive.
Slab leaks are especially serious in San Antonio. Water migrating under a foundation can erode the soil beneath the slab and cause costly structural movement. O5 Plumbing uses advanced acoustic and thermal leak detection tools to locate leaks precisely minimizing the invasive work needed to reach and repair them.
Microbial growth can colonize wet building materials remarkably fast. Hidden leaks inside walls create ideal conditions that often go untreated for months, allowing colonies to spread undetected.
Water saturates wood framing, subfloor, and drywall. Over time it causes rot, warping, and the collapse of structural elements.
Water reaching electrical panels, outlets, or wiring creates serious shock and fire risk. Leaks near electrical systems need immediate attention.
Moisture behind walls attracts termites, cockroaches, and rodents. A hidden leak can be the source of a recurring pest problem.
Even a small continuous leak wastes thousands of gallons per month. An unexplained spike in your bill is one of the earliest warning signs.
"The most expensive leak is the one you didn't find in time."

Understanding the cause is the first step toward a lasting fix.
Galvanized steel, cast iron, and older copper lines eventually corrode and develop pinhole leaks. Homes over 30 years old are most at risk.
Pressure above 80 PSI stresses joints, valves, and fittings. Over time, high pressure causes small failures that worsen quickly.
Hard water minerals and soil chemistry eat away at metal pipes and fittings from both inside and outside, eventually causing leaks.
San Antonio freeze events like the 2021 winter storm crack pipes that rapidly contract. Even mild thermal cycling stresses connections over years.
Improperly fitted joints, wrong material combinations, and undertightened connections are common sources of slow, hidden leaks.
Tree roots seek moisture and enter sewer and water lines through tiny cracks. Once inside, they grow and eventually cause major blockages and breaks.
Most plumbers diagnose leaks by opening walls. We use precision tools to locate leaks non-invasively before any demolition happens. That means less damage to your home and a faster, cleaner repair.

"We had a slab leak that two other plumbers couldn't find. O5 came out, used their detection equipment, marked the exact spot, and made a very small cut in the slab to fix it. Professional, honest, and half the mess I expected. Worth every penny."
"My water bill jumped unexpectedly with no obvious reason. Called O5 and they found a slow leak behind our bathroom wall within an hour. Fixed it the same visit. Bill is back to normal. I had no idea leaks could be that hidden glad I called when I did."
"Pipe burst during the freeze. I called O5 at 6am and someone answered immediately. They had a tech at my house by 9am and water back on by early afternoon. Absolutely incredible response. Price was fair and the work was clean. These are my plumbers for life."
Check your water meter. Turn off everything in the house that uses water, then watch the meter dial for a few minutes. If it moves at all, water is leaving the system somewhere. Common culprits include running toilets, slow drips under sinks, and slab leaks. Call us we'll find it.
First, find and close your main water shutoff valve typically near the meter or where the main line enters the house. Then open a faucet to relieve remaining pressure in the line. Move valuables away from the water and call O5 immediately. Don't wait to see if it slows down on its own.
We use acoustic listening equipment that amplifies the sound of water escaping from pipes, letting us pinpoint the leak location without opening walls. For slab leaks, thermal imaging helps identify temperature anomalies caused by water movement under the concrete. We locate the leak precisely before any cutting happens.
No. Even slow leaks can cause microbial growth within 24-48 hours on wet building materials. What starts as a small pipe drip can saturate insulation, soak into wood framing, and create microbial growth behind drywall before you ever see visible staining. Address leaks immediately the longer they sit, the more expensive the damage becomes.
Yes. Slab leaks are one of our specialties. We use electronic detection equipment to locate the leak precisely beneath the concrete, minimizing the size of the opening required. In some cases, re-routing the pipe above the slab is a better long-term solution than accessing the old line we'll give you honest options and let you decide.
