Gonzales homeowners call us for everything from a single pinhole leak to a full under-slab re-pipe. The work varies by neighborhood: Gonzales Beach and Foul Bay see more copper pipe failures from salt air, while Gonzales North and Gonzales South deal with aging cast iron and galvanized lines. If you need affordable Slab Leak Repair in Gonzales TX, we scope the job, show you the leak location on camera, and give you a flat price before we cut. Here is what we run in Gonzales every week.
We locate under-slab leaks in Gonzales homes using acoustic listening devices, thermal imaging cameras, and pressure testing gauges. In Gonzales North and Gonzales South, where cast iron and galvanized lines are common, we map the line with a pipe locator before confirming the break. You get a marked location and a repair plan the same day.
View details ↗02Electronic leak detection equipment lets us hear water escaping a pipe through concrete. We use LeakTronics and American Leak Detection gear to isolate the leak in Gonzales Beach and Foul Bay homes where coastal moisture confuses visual inspection. The process takes 60 to 90 minutes and avoids exploratory demolition.
View details ↗03We use FLIR thermal imaging cameras to spot hot spots on floors, which often signal a hot-water slab leak. In Gonzales South, where many homes have original copper hot-water lines under tile, thermal imaging narrows the search to a 12-inch zone. That means one small cut instead of a full room tear-out.
View details ↗04Acoustic listening devices pick up the sound of pressurized water escaping a pipe. We use them in Gonzales North and the Oak Bay Border on homes with copper pipes, where a pinhole leak can run for months before it surfaces. The equipment works through 4 to 6 inches of concrete.
View details ↗05Once we locate the break, we repair the under-slab pipe with copper, PEX, or PVC couplings rated for buried service. In Gonzales Beach, we often replace a corroded section rather than patch it, because salt air will find the next weak point. We pressure-test the line at 80 PSI before backfilling.
View details ↗06When a Gonzales home has multiple failures in the same line, replacement beats repeated repairs. We run new PEX or copper under the slab in Gonzales South and Gonzales North, routing around the original failed run. Most replacements take one to two days and include concrete patch and restoration.
View details ↗07Tunneling lets us reach under-slab pipes without breaking the full slab. We use trenchless tunneling equipment in Gonzales homes with finished floors or tile that would be expensive to replace. The tunnel runs from outside the foundation to the leak point, and we backfill and compact when the repair is done.
View details ↗08When a repair requires direct access, we cut concrete with saws and break it with jackhammers. In Gonzales South, where many slabs are post-tension, we use a concrete saw and locate the cables before cutting. We remove the debris and haul it off the same day.
View details ↗09After the pipe repair, we patch the slab with concrete patch mix matched to your existing floor. In Gonzales North and Gonzales Beach, we finish the patch so it accepts tile, laminate, or carpet adhesive. The patch cures in 24 to 48 hours before we set the finish floor.
View details ↗10Foundation leaks in Gonzales often show up as water pooling at the base of a wall or a musty smell in a closet. We trace the source with moisture meters and pressure testing gauges, then repair the failed line. In Foul Bay, where the water table is high, we also check the foundation drain.
View details ↗11A failed main water line in Gonzales can soak a yard and spike your bill. We locate the break with electronic leak detection equipment and repair the line with copper or PEX. In Gonzales Beach, we often find the break at the meter or where the line enters the slab.
View details ↗12When a Gonzales water line has failed more than twice, replacement is the cheaper long-term call. We run new PEX or copper from the meter to the house, usually in one day. In Gonzales North, we replace galvanized service lines that have rusted closed.
View details ↗13Sewer line breaks in Gonzales often come from cast iron pipes that have cracked or root intrusion. We run a RIDGID SeeSnake camera through the line to find the break, then repair or reline it. In Gonzales South, we see a lot of root damage near mature trees.
View details ↗14When a Gonzales sewer line is collapsed or bellied, replacement is the only fix. We run new PVC pipe from the house to the city main, usually in one to two days. In Foul Bay, we handle the high water table with proper bedding and backfill.
View details ↗15Drain line leaks in Gonzales show up as a wet spot on the floor or a sewer smell in the house. We locate the break with a video pipe inspection camera and repair the line with PVC or cast iron couplings. In Gonzales North, we often replace a section of rusted cast iron.
View details ↗16When a Gonzales drain line is scaled or cracked along its length, replacement is the right call. We run new PVC under the slab in Gonzales South and Gonzales Beach, tying into the existing stack. Most replacements take one to two days.
View details ↗17Sometimes the smartest fix in Gonzales is to reroute the pipe above the slab or through the attic. We do this in Gonzales Beach homes where repeated slab leaks have made the under-slab run unreliable. The new line is PEX or copper, and we pressure-test it before closing up.
View details ↗18Pipe relining lets us repair a Gonzales drain line from the inside without digging. We pull an epoxy-saturated liner through the pipe and cure it in place. In Gonzales North, where cast iron lines are common, relining adds decades of life without breaking the slab.
View details ↗19Epoxy pipe lining seals pinholes and small cracks in copper and cast iron lines. We use it in Gonzales South and Gonzales Beach on lines that are failing but not yet collapsed. The lining is food-grade and rated for potable water.
View details ↗20Pinhole leaks are the most common copper pipe failure we see in Gonzales Beach and Foul Bay. Salt air and coastal moisture eat through the pipe wall from the inside. We repair the section with a copper coupling or replace the run if multiple pinholes are present.
View details ↗21Copper lines in Gonzales homes fail at joints and at pinholes. We repair them with soldered copper couplings or, when the line is too thin, replace the section with new copper. In Gonzales North, we often find copper lines that have been patched before.
View details ↗22PEX is the go-to replacement for failed copper and galvanized lines in Gonzales. We repair PEX with brass or plastic couplings and stainless clamps. In Gonzales South, we often tie new PEX into an existing copper system at the water heater.
View details ↗23PVC drain lines in Gonzales can crack from soil movement or root pressure. We repair them with PVC couplings and primer. In Foul Bay, where the water table is high, we check for bellies in the line before we close the trench.
View details ↗24Cast iron drain lines in Gonzales North and Gonzales South are often 50 to 70 years old and rusted through. We repair them with cast iron couplings or replace the section with PVC. When the line is too far gone, we recommend relining or replacement.
View details ↗25Galvanized supply lines in older Gonzales homes rust closed from the inside. We replace them with PEX or copper, usually from the meter to the water heater. In Gonzales North, this often restores water pressure to the whole house.
View details ↗26A leaking water heater in Gonzales is often a failed fitting or a cracked tank. We repair the fitting or replace the unit if the tank is compromised. In Gonzales Beach, we check the pan and drain line at the same time.
View details ↗27When a Gonzales water heater is 10 to 12 years old and leaking, replacement is the right call. We install 40- and 50-gallon units and haul the old one away. In Gonzales South, we often upgrade the pan and expansion tank at the same time.
View details ↗28High water pressure from the city main can stress every pipe in a Gonzales home. We test pressure at the hose bib and repair or replace the regulator valve. In Gonzales Beach, we often find pressure above 80 PSI, which accelerates pinhole leaks.
View details ↗29A failed main shut-off valve in Gonzales means you cannot stop the water in an emergency. We repair or replace the valve at the meter or at the house entry. In Gonzales North, we often find gate valves that have not been turned in 20 years.

Groundwater can mask the sound of a slab leak and confuse leak detection equipment. It also makes trenching wet and messy.
We use pressure testing gauges and thermal imaging cameras to isolate the leak from groundwater. For repairs, we dewater the trench and use proper bedding so the new pipe is not sitting in mud.
