Emergency Slab Leak Response in Petaluma
A slab leak that is flooding floors or causing water to bubble up through tile needs fast attention. We respond quickly, help you shut off the water and isolate the leaking side if possible. That often lets you keep some water service until the repair. Then we locate and fix the leak.

Video Pipe Inspection for Sewer Leaks in Petaluma, CA
Sewer line issues under a slab can also look like slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations. This is vital if the issue isn't a pressurized water line, helping us determine if a sewer line repair is needed instead for your Petaluma home.
Repiping After Multiple Slab Leaks in Petaluma, CA
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of repeat slab leaks. We can typically complete a full repipe in two to four days.
Water and Sewer Line Slab Leaks in Petaluma, CA
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are equipped to identify both types of leaks, which present different challenges. Sewer line leaks often involve foul odors and slow drainage, while water line leaks can show up as wet spots or high water bills in your Petaluma, CA home. We have separate methods for each.
Slab Leak Reroutes in Petaluma
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We usually use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is popular when the slab is covered in tile or hardwood.
Hot Water Slab Leak Detection in Petaluma
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs nonstop and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before marking the spot.
Electronic Leak Detection in Petaluma
For elusive leaks, our electronic leak detection equipment sends a signal through your pipes and measures changes that indicate a breach. This technology allows us to locate leaks in many pipe materials, including copper, PEX and PVC, commonly found in Petaluma homes. It helps prevent exploratory digging, saving you time and money.

Frequently Asked Questions About Slab Leak Detection in Petaluma
The cost for professional slab leak detection in Petaluma, CA usually ranges from $250 to $700, depending on the complexity of the leak and the time required for diagnosis.

Yes. Water leaking under the slab can cause expansive soil to swell or wash away supporting soil. Over time this can lead to cracks and settling. Fixing leaks quickly protects the foundation.
Common signs of a slab leak include unusually high water bills, warm spots on your floor, the sound of running water when no fixtures are in use, visible cracks in the foundation, damp or wet spots on carpets or flooring and a sudden drop in water pressure. Musty odors can also point to moisture buildup.
Many policies cover the cost to access the leak and repair resulting water damage, though the pipe itself may not be covered. Coverage varies by insurer. We provide photos and a detailed report for your claim.
Common signs of a slab leak in Northern California homes include sudden increases in water bills, warm spots on your floor, the sound of running water when no fixtures are in use, damp or mildewy smells and visible cracks in your foundation or walls. Pooling water outside your home near the foundation can also be a clear indicator.
Many older homes here sit on raised foundations with crawlspaces, which make supply and drain repairs easier to reach than slab work. Hard water can also corrode copper pipes from the inside. Pipes can wear against concrete or gravel as they expand with hot water, and over time these factors cause pinholes and cracks.
For significant slab leak repairs, especially those involving excavation or extensive re-piping, a plumbing permit from the local building department is often required. FBL Plumbing handles all necessary permitting processes so your repair is compliant with local codes and regulations, protecting your investment.
