Pipe Repair & Repiping Services

Aging, damaged, or corroded pipes are a serious concern for property owners in Los Angeles. Whether you are dealing with a pinhole leak, a burst pipe, or an entire plumbing system that has reached the end of its useful life, Coast City Plumbing delivers professional pipe repair and repiping services that protect your property and restore reliable water flow. Our licensed plumbers assess every situation carefully and recommend the most cost-effective and lasting solution for your specific needs.

Leak Detection

Not all pipe leaks are visible. Many occur behind walls, under floors, or beneath concrete slabs where they can go undetected for weeks or months. During that time, hidden leaks waste water, increase your utility bills, promote mold growth, and cause structural damage. Coast City Plumbing uses advanced leak detection technology including acoustic listening devices, thermal imaging, and pressure testing to pinpoint the exact location of leaks without unnecessary demolition. Accurate leak detection saves you money by allowing us to make targeted repairs rather than tearing out large sections of wall or flooring.

Copper Repiping

Copper has been the gold standard for residential plumbing for decades. It is durable, corrosion-resistant, and has a strong track record of lasting 50 years or more in ideal conditions. Coast City Plumbing offers complete copper repiping for homes and businesses that need to replace old galvanized steel, polybutylene, or deteriorating copper lines. Our copper repiping service includes removal of old pipes, installation of new Type L copper throughout your property, patching of access points, and a thorough pressure test to verify the integrity of the new system.

PEX and PVC Piping

Cross-linked polyethylene, commonly known as PEX, has become a popular alternative to copper for residential repiping projects. PEX is flexible, resistant to scale and chlorine, and less expensive than copper while still offering excellent longevity. It is particularly well-suited for retrofitting older homes because its flexibility allows it to be routed through existing wall cavities with fewer connections and fittings. We also work with PVC and CPVC piping for drain, waste, and vent applications. Our plumbers help you choose the right piping material based on your budget, water chemistry, and long-term goals.

Whole-House Repiping

If your home was built before 1970, there is a good chance it still has galvanized steel pipes that are corroding from the inside out. Galvanized pipes develop rust buildup that restricts water flow, discolors your water, and eventually leads to leaks and pipe failures. Whole-house repiping replaces every supply line in your home with new copper or PEX piping. While this is a significant investment, it eliminates the ongoing cycle of patch repairs, improves water pressure, enhances water quality, and adds substantial value to your property. Most whole-house repiping projects can be completed in one to three days depending on the size and complexity of your home.

Slab Leak Repair

A slab leak occurs when a water supply line or drain pipe running beneath your concrete foundation develops a leak. Signs of a slab leak include unexplained increases in your water bill, the sound of running water when no fixtures are in use, warm spots on the floor, damp carpet, or cracks in your foundation. Slab leaks require specialized repair techniques. Depending on the severity and location, we may perform a spot repair by accessing the pipe through the slab, reroute the affected line above ground, or use epoxy pipe lining to seal the leak from within. Each approach has specific advantages, and we explain all options clearly before beginning work.

Pinhole Leak Repair

Pinhole leaks are small perforations that develop in copper pipes due to aggressive water chemistry, high pH levels, or electrolysis between dissimilar metals. While each individual leak is tiny, pinhole leaks tend to occur in clusters and worsen over time. Repairing pinhole leaks one at a time is often a losing battle. If your home is experiencing multiple pinhole leaks, we typically recommend a partial or whole-house repipe to address the root cause rather than chasing individual leaks indefinitely.

Burst Pipe Emergency Repair

A burst pipe is a plumbing emergency that demands immediate attention. Whether caused by freezing temperatures, excessive water pressure, corrosion, or physical damage, a burst pipe can release hundreds of gallons of water per hour into your home. Coast City Plumbing provides emergency pipe repair service to stop the damage fast. Our technicians arrive equipped to shut off water, contain the affected area, and make permanent repairs on the spot. We also coordinate with water damage restoration professionals when needed to help you recover quickly.

Galvanized Pipe Replacement

Galvanized steel pipes were standard in homes built before the 1960s. Over decades, the zinc coating inside these pipes corrodes, allowing rust to accumulate and restrict water flow. Eventually, the pipes develop leaks at joints and along weakened sections. If your home has galvanized pipes, replacement is not a matter of if but when. We specialize in removing old galvanized plumbing and replacing it with modern copper or PEX piping that will provide reliable service for your home.

Trenchless Pipe Repair

For underground pipe problems, trenchless repair methods offer a minimally invasive alternative to traditional excavation. Techniques such as pipe bursting and cured-in-place pipe lining allow us to repair or replace underground pipes without digging up your yard, driveway, or landscaping. Trenchless repair is faster, less disruptive, and often more cost-effective than open-trench methods. Our team evaluates your specific situation to determine whether trenchless repair is a viable option for your property.
