Cold Water Slab Leak Repair in Fullerton
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, locate the leak and repair or reroute it. Fixing cold leaks promptly helps protect your foundation.

PEX Repiping for Slab Leaks in Fullerton, CA
If multiple slab leaks indicate 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 Fullerton home, providing a brand-new, leak-free plumbing system that will last for decades.
Hot Water Slab Leak Repair in Fullerton, CA
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.
Emergency Slab Leak Services in Fullerton
A burst pipe under your foundation can cause rapid and severe water damage, calling for immediate attention. FKM Plumbing offers emergency slab leak repair services in Fullerton to address urgent situations. Our rapid 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.
Slab Leak Reroute in Fullerton
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is simplest. Reroutes end future leaks in that section of pipe.
Emergency Slab Leak Repair in Fullerton, CA
A large slab leak can push water up through flooring or into walls quickly. We help you shut off the water and send a technician to isolate the leaking line. Often we can restore water to the rest of the house while we plan the repair. Fast action limits flooring damage and soil saturation.

Frequently Asked Questions About Slab Leak Repair in Fullerton
Slab leak detection typically 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.
Slab leaks can be caused by several factors, including shifting soil that puts stress on pipes, corrosive water chemistry leading to pinhole leaks in copper, poor pipe installation, and general aging of plumbing materials. Earthquakes are a constant consideration in Southern California, and seismic straps and flexible connectors help keep water and gas lines intact during shaking. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters.
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. Plumbing work in Southern California follows the state plumbing code, which is based on the Uniform Plumbing Code with state amendments. FKM Plumbing handles all necessary permitting on your behalf, so your repair is fully compliant.
Detection typically takes one to three hours. Spot repairs and reroutes usually take one to two days.
Yes, FKM Plumbing stands behind the quality of our work. We offer a warranty on our slab leak repairs, providing you with peace of mind. The specific terms of the warranty will be discussed with you before any work begins.
Slab leak repair is a highly specialized task that should only be handled by licensed professionals. Improper detection or repair can lead to further damage to your home's foundation, mold growth, and costly structural issues. DIY attempts often void warranties and can violate local plumbing codes in Fullerton.
Yes. We provide a written workmanship warranty, and pipe and fittings carry manufacturer warranties. We go over coverage before starting work.
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 immediately after detecting a leak. We can help provide needed documentation for your claim.
