Direct Slab Leak Repair in O'Fallon, MO
When a slab leak is localized and accessible, direct repair is often the most practical solution. This involves carefully jackhammering a small section of your foundation to expose the damaged pipe, then repairing or replacing the compromised section. Our technicians are skilled in careful concrete cutting and restoration, so the repair is effective and the area is professionally restored. We use durable materials designed to hold up to soil movement under the slab.

Direct Slab Penetration Repair in O'Fallon, MO
When a slab leak is directly accessible and localized, direct slab penetration is often the most efficient repair method. This involves carefully cutting a small section of your concrete slab to access and repair or replace the damaged pipe section. Our team makes sure the repair is fully compliant with Missouri plumbing codes and the slab is correctly restored, preventing future issues. We take great care to contain dust and debris during this process in your O'Fallon home.
Emergency Slab Leak Services in O'Fallon
A burst pipe under your foundation can cause rapid and severe water damage, calling for immediate attention. FGV Plumbing offers emergency slab leak repair services in O'Fallon to address urgent situations. Our quick response team is equipped to locate the leak, limit water damage, and perform temporary or permanent repairs to secure your property. Don't let a sudden slab leak turn into a disaster.
Hot Water Slab Leak Repair in O'Fallon, MO
Hot water lines leak under slabs more often than cold lines because heat expands and contracts the pipe against concrete and gravel. Mineral scale and constant recirculation can wear the pipe wall faster. We repair the leak or reroute the hot line, and we can adjust recirculation pumps to limit wear. Warm floors and higher gas or electric bills are common signs.
Commercial Slab Leak Repair in O'Fallon, MO
Businesses in O'Fallon also face the risk of slab leaks, which can disrupt operations and lead to costly downtime. FGV Plumbing provides complete commercial slab leak repair services, tailored to the specific needs of your business. We work quickly to diagnose and fix the problem, so your commercial property in Missouri can return to normal operations with minimal interruption while staying safe and compliant.
Slab Leak Pipe Rerouting in O'Fallon
For more complex or recurring slab leaks, or when the original piping is severely deteriorated, pipe rerouting is an effective long-term solution. This method involves abandoning the leaky pipe under the slab and installing new plumbing lines through walls or the attic, bypassing the foundation entirely. This removes future slab leak risks from that particular line and is often preferred for older homes in O'Fallon with aging copper or galvanized pipes.
Cold Water Slab Leak Repair in O'Fallon
Cold water slab leaks are harder to feel but still waste water and wet the soil. They often show up as a high water bill or a meter that moves with all fixtures off. We isolate the cold line, find the leak and repair or reroute it. Fixing cold leaks quickly helps protect your foundation.

Slab Leak Detection in O'Fallon
We start by shutting off fixtures and watching the meter to verify a leak. Then we isolate the hot and cold lines to determine which one is leaking. Using acoustic ground microphones, we listen for the sound of escaping water through the concrete. Thermal imaging shows hot water leaks as warm areas on the floor surface.

We use high-quality, durable piping materials from reputable brands known for longevity and performance. This includes PEX piping from established manufacturers like Uponor or Viega, and high-grade copper piping when appropriate, for lasting repairs in your O'Fallon home.
Depending on the extent of the repair, especially if it involves major structural work, pipe rerouting, or changes to the main water line, a plumbing permit may be required by local authorities.

Homeowner's insurance policies vary, but many cover the cost of damage caused by a sudden and accidental slab leak, although the repair of the pipe itself might not be covered. It is best to check with your insurance provider right away after detecting a leak. We can help provide necessary documentation for your claim.
