Minimally invasive, fast, and cost-effective repairs without digging up your yard.
If your sewer line is damaged, cracked, or corroded, you don’t need to sacrifice your yard to fix it. Trenchless sewer repair using epoxy spray coating allows us to restore damaged pipes from the inside—sealing cracks, stopping root intrusion, and eliminating leaks without extensive digging. At LGE Prime Plumbing, we specialize in this proven technology, protecting your San Diego property while delivering long-lasting sewer solutions.
Trenchless sewer repair is a minimally invasive method that restores damaged pipes from the inside using epoxy spray coating. Instead of excavating your yard, driveway, or landscaping to access the damaged section, we clean the pipe thoroughly and apply a protective epoxy resin coating directly to the interior walls. The epoxy seals every crack and crevice, creating a seamless, corrosion-resistant barrier that protects your pipe for decades—without any structural liner needed.
Trenchless technology has revolutionized sewer repair in San Diego. Where homeowners once faced weeks of disruption and landscape destruction, they now have a fast, affordable alternative that leaves their property intact.

We begin with a professional camera inspection to locate the damage, measure its extent, and determine if your line is a candidate for epoxy coating. This camera footage shows us exactly what we’re dealing with—cracks, root intrusion, corrosion, or offset sections—so we can recommend the right solution.
Before the epoxy coating is applied, the pipe must be thoroughly cleaned. We use high-pressure hydro jetting to remove grease buildup, roots, sediment, and debris from the entire damaged section. This ensures the epoxy bonds properly to the pipe walls and creates a durable, long-lasting seal.
Using specialized spray application equipment, we apply an epoxy resin coating directly to the cleaned interior walls of the pipe. The epoxy conforms to the exact shape of your pipe, filling micro-cracks and sealing all damage points. The application is precise and comprehensive, treating the entire problem area in one pass.
The epoxy coating hardens through either air-dry or heat curing, depending on the system used. This process typically takes 24-48 hours. Once fully cured, the epoxy creates a seamless, corrosion-resistant protective barrier inside your pipe—stronger and more durable than the original pipe wall.
We perform a final camera inspection to confirm the epoxy coating has cured properly, sealed all cracks and root intrusions, and restored proper pipe function. Flow testing ensures wastewater moves freely through the repaired line.
Epoxy spray coating fills every crack, void, and corrosion point in your pipe. Unlike patching or partial repairs, epoxy coating treats the entire interior surface, creating a comprehensive protective barrier that stops leaks and prevents future damage.
Roots enter pipes through small cracks and holes. Epoxy coating seals these entry points completely, preventing roots from penetrating even if they try to grow into the pipe. Combined with hydro jetting to remove existing roots, epoxy coating provides lasting protection against root damage.
Epoxy is naturally corrosion-resistant, protecting your pipe from continued deterioration. San Diego’s hard water and coastal salt spray can damage pipes over time—epoxy coating stops this process cold and extends your pipe’s lifespan for decades.
Unlike traditional lining methods, epoxy spray coating doesn’t require inserting a felt or fiberglass liner. The epoxy is applied directly to the pipe wall, making the process faster, simpler, and more cost-effective while still delivering a durable, long-lasting result.
Epoxy spray coating is ideal for:
However, epoxy coating does have limits. If your line is severely collapsed in multiple locations, completely broken, or requires structural replacement beyond a certain extent, traditional excavation and replacement or pipe bursting may be necessary. During our camera inspection, we’ll honestly assess whether your line qualifies for epoxy coating or needs full replacement.
No trenches across your yard, driveway, patio, or landscaping. We access the pipe through existing cleanout points, leaving your property virtually undisturbed. This is a game-changer for homeowners with mature trees, established gardens, or hardscaping they want to protect.
Most epoxy coating projects are completed in 1-2 days. Compare that to traditional excavation and replacement, which can take weeks or longer. Your sewer system is back to normal quickly, with minimal disruption to your daily life.
Epoxy coating costs significantly less than traditional excavation and replacement. You save on labor (fewer hours needed), equipment (no heavy machinery required), and restoration costs (no landscaping repair needed). Many San Diego homeowners save 30-50% compared to traditional methods.
A properly applied epoxy coating lasts 20-30+ years with proper maintenance. The coating creates a durable, corrosion-resistant barrier that’s often more protective than the original pipe material. You’re getting a decade-spanning solution, not a temporary fix.
Epoxy coating creates less environmental disruption than traditional digging. No heavy equipment, no soil disturbance, and modern epoxy materials are environmentally safe once cured. It’s a sustainable solution for property owners who care about their impact.
Whether your line is cast iron, clay, PVC, or concrete, epoxy coating can protect it. This is especially important in San Diego, where older homes frequently have decades-old cast iron or clay sewer lines.
San Diego’s warm climate, mature landscaping, and clay soils make root intrusion the most common sewer problem we encounter. Tree roots seek out moisture and penetrate small cracks in pipes, causing blockages, backups, and line damage over time.
Epoxy coating is the perfect solution for root intrusion because it seals every crack and crevice where roots can enter. Even if tree roots broke into the original pipe, the epoxy barrier stops them cold—protecting your line from future intrusion for years to come. Combined with hydro jetting to clear existing roots, epoxy coating gives you complete protection against this persistent San Diego problem.
San Diego’s clay soils settle over time, causing pipes to shift, crack, and develop gaps. Epoxy coating seals these cracks and prevents water infiltration, protecting your system without the massive excavation traditional repair would require.
Homes near the coast experience accelerated corrosion from salt spray and mineral-rich water. Cast iron and clay pipes corrode faster in these conditions. Epoxy coating creates a corrosion-resistant barrier that seals and protects corroded sections.
San Diego’s hard water causes mineral scale to accumulate inside pipes over time. This reduces flow capacity and can trap roots. Hydro jetting before epoxy coating clears these deposits and restores proper flow, while the epoxy protects against future buildup.
San Diego’s varied terrain means pipes are sometimes installed at challenging angles or depths. Epoxy coating works at any elevation and doesn’t require the extensive landscaping rework that traditional digging would.

FAQs
A properly applied epoxy coating typically lasts 20-30+ years, with many systems lasting even longer with proper maintenance. The epoxy creates a durable, corrosion-resistant barrier that protects your pipe from future damage, often performing better than the original pipe material.
Yes! The epoxy coating cures quickly—typically within a few hours. Most homeowners can use their sewer system the same day the repair is completed. We'll confirm the coating is fully cured before signing off on the job.
Yes. The epoxy resins used in trenchless sewer repair are industry-approved and safe for both sewer lines and potable water pipes once fully cured. The materials are non-toxic and create a sealed, durable barrier that protects water quality.
Common warning signs include frequent clogs, slow drains, foul odors coming from drains, gurgling noises in pipes, soggy patches in your yard, or unusually high water bills. If you notice any of these issues, a professional camera inspection can determine if your line needs epoxy coating or other repair.
San Diego homeowners typically save 30-50% with epoxy coating compared to traditional excavation and replacement. You eliminate costly landscaping restoration, reduce labor hours, and avoid heavy equipment fees. Many homeowners save thousands of dollars by choosing trenchless repair.
Absolutely. Root intrusion is the #1 sewer problem in San Diego, and epoxy coating is the perfect solution. We first hydro jet to remove existing roots, then apply the epoxy coating to seal every crack where roots can penetrate. This prevents future root damage for decades.
Most epoxy coating projects are completed in 1-2 days, depending on the size and complexity. This includes camera inspection, hydro jetting, epoxy application, and final testing. Compare this to traditional excavation, which can take weeks including landscaping restoration.
No. Because epoxy coating is a trenchless method, it creates minimal disruption. You can stay in your home during the repair. We only need small access points to the sewer line, so there's no heavy equipment, digging, or extended shutdown of your sewer system.
If your line is severely collapsed, crushed, or damaged beyond what epoxy coating can repair, we may recommend full line replacement using pipe bursting (still trenchless with only 1-2 access points) or traditional excavation and replacement. We'll assess your line during camera inspection and recommend the right solution.
Yes. Epoxy coating works on cast iron, clay, PVC, and concrete pipes. This is especially important in San Diego, where many older homes have decades-old cast iron or clay sewer lines that are prone to corrosion and root intrusion. Epoxy coating protects and extends the life of these pipes.
The best way to know is with a professional camera inspection. We'll look inside your pipe, identify the damage, assess whether it's structurally sound enough for coating, and recommend the ideal solution. Most San Diego sewer lines qualify for epoxy coating, but we'll give you an honest assessment.
No. Unlike traditional excavation that tears up driveways, patios, and yards, epoxy coating is trenchless. We access your pipe through existing cleanout points, leaving your landscaping, driveway, and hardscape completely intact. This is a major advantage for San Diego homeowners with mature trees and established gardens.
