Spot Repair Through the Slab in Kennewick, WA
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a practical option. We cut a small opening, excavate to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.

Electronic Slab Leak Detection in Kennewick
Locating a hidden slab leak takes specialized tools. Our plumbers use sensitive electronic listening devices and thermal imaging cameras to pinpoint the exact location of the leak under your concrete foundation. This precision detection minimizes the need for extensive concrete removal, saving you time and money. We can detect leaks in both hot and cold water lines, as well as sewer lines, for a complete diagnosis of your Kennewick home.
Hot Water Slab Leak Repair in Kennewick, WA
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.
Slab Leak Pipe Rerouting in Kennewick
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 Kennewick with aging copper or galvanized pipes.
Direct Slab Leak Repair in Kennewick, WA
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 damaged section. Our technicians are skilled in careful concrete cutting and restoration, so the repair is effective and the area is properly restored. We use durable materials designed to hold up to soil movement under the slab.
Cold Water Slab Leak Repair in Kennewick
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 promptly helps protect your foundation.
PEX Repiping for Slab Leaks in Kennewick, WA
If multiple slab leaks point to a systemic issue with your home's original plumbing, a full PEX repipe might be the most cost-effective and durable solution. PEX tubing is flexible, corrosion-resistant, and less prone to leaks caused by foundation shifts, making it a strong choice for many homes. We can replace all the water supply lines in your Kennewick home, providing a brand-new, leak-free plumbing system that will last for decades.

Direct Slab Penetration Repair in Kennewick, WA
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 Washington plumbing codes and the slab is correctly restored, preventing future issues. We take real care to contain dust and debris during this process in your Kennewick home.

Mid-century homes often have galvanized supply lines and cast iron drains, while some 1980s and 1990s homes were plumbed with gray polybutylene. When water lines run under the concrete, water chemistry, heat and shifting soil can make slab leaks one of the most common plumbing repairs in Kennewick, WA.

Frequently Asked Questions About Slab Leak Repair in Kennewick
Slab leak detection usually costs $150 to $450. Spot repairs through the slab usually run $1,500 to $4,000, and reroutes often range from $1,800 to $5,000. Whole-house repipes are quoted based on home size.
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. FHN Plumbing will handle all necessary permit applications so your slab leak repair is fully compliant with local building codes.
Yes. Water seeping into flooring, carpet padding and wall bottoms can lead to mold growth. Repairing the leak quickly and drying the area helps prevent it.
FHN Plumbing stands behind our slab leak repair work with a full warranty on parts and labor. The specific terms of the warranty will be provided with your estimate, for peace of mind about the durability and quality of our repairs in Kennewick.
Yes, many slab leak repairs, especially those involving rerouting or repiping, require permits from the local permitting office to comply with building and plumbing codes. Seismic strapping on water heaters is a common inspection item here, and FHN Plumbing installs to satisfy local requirements. FHN Plumbing handles all necessary permitting on your behalf, so your repair is fully compliant.
A slab leak specifically refers to a leak in the plumbing pipes embedded within or beneath your home's concrete slab foundation. Other water leaks might occur in exposed pipes, walls, or ceilings, but slab leaks are hidden and often more difficult to detect and repair due to their location.
Absolutely. Water steadily leaking under your foundation can erode the soil, leading to voids and uneven settlement, which can cause cracks in your foundation, walls, and flooring. Steep slopes and wet soils can move over time, which stresses buried sewer and water lines and sometimes separates joints.
If the pipe is in good condition and the leak is easy to reach, a spot repair can work. If the pipe is old or you have had prior leaks, a reroute is often the better long-term value.
