Trenchless Pipe Repair in San Clemente, CA
Leaking cast iron main under the foundation, failing city connection in the street. Team Rooter excavated under the home, removed the cast iron main, installed a cleanout, then performed a 45-foot pipe burst in the street replacing old cast iron with HDPE — street-to-property, fully warranted.
San Clemente, CA — Trenchless Pipe Burst & Cast Iron Removal
Full Sewer Replacement — Under the Home and Into the Street
This San Clemente home had a failing 3" cast iron main underneath the foundation that was leaking into the soil — a slow leak that had likely been going for some time before symptoms appeared inside the home. The problem extended into the street, where the existing cast iron main connected to the city pipe.
Our team first excavated under the home to access and remove the cast iron main and connected a new cleanout. We then opened the street to expose the cast iron at the city connection, and from that access point performed a 45-foot pipe burst — replacing the old cast iron with high-density polyethylene pipe all the way from property to city curb connection. All connections were made with 4" ARC couplings. The street was backfilled and asphalted.
All work is warranted on parts and labor — both street and property.
How We Got the Job Done
Confirm the full extent of the failing cast iron — under home and street
A camera inspection confirmed both the under-slab leak and the condition of the main running from the home to the city curb connection. The footage established the scope — this was not a spot repair situation — and determined the pipe burst was the correct approach for the street section.
Access and remove the leaking cast iron main under the foundation
We excavated under the home to reach the failing 3" cast iron main that was leaking into the soil. The old cast iron was removed and a new cleanout was connected at the access point, giving permanent service access to the system from above ground going forward.
Open the street to expose the cast iron at the city pipe connection
We cut and excavated the street to expose the point where the house cast iron main connected to the city pipe. This gave us the entry point for the pipe burst and allowed us to cut out the old cast iron at the city side of the connection.
Pull HDPE pipe through the old cast iron main — no full trench needed
From the street access point, we performed a 45-foot pipe burst — the bursting head fractures the old cast iron outward while simultaneously pulling new HDPE pipe behind it. The result is a new, continuous pipe in the exact same path as the old one, with no open trench required across the full 45-foot run.
ARC couplings on property and street, camera verify, backfill
All connections — property side and street side — were made with 4" ARC couplings. A post-burst camera run verified the new pipe end-to-end for alignment, connection seal quality, and flow. The street excavation was backfilled and asphalted to restore the surface.
What This Job Required
Camera Line Inspection
Full-run inspection confirming under-slab leak, street pipe condition, and scope — established the pipe burst as correct approach before any excavation.
Under-Home Excavation
Excavation beneath the foundation to access and remove the failing 3" cast iron main leaking into the soil.
Cleanout Installation
New cleanout connected at the under-home access point — permanent service access without future excavation.
45-Foot Pipe Burst
Trenchless replacement of old cast iron with HDPE pipe — bursting head fractures and displaces old pipe while pulling new pipe in one continuous pass.
ARC Coupling Connections
All connections on property and street side made with 4" ARC couplings — camera-verified after installation.
Asphalt Restoration & Warranty
Street backfilled and asphalted. All work — street and property — warranted on parts and labor.
Why Cast Iron Sewer Lines Fail in San Clemente
San Clemente was largely developed in the 1950s through 1970s, and a significant portion of the original residential sewer laterals were installed in cast iron — a material that corrodes from the inside out over decades of use. The combination of Southern California's slightly acidic soil and decades of hydrogen sulfide exposure inside the pipe accelerates corrosion on the pipe's interior wall.
When cast iron fails under a slab or foundation, the leak is often slow and silent — the soil absorbs the wastewater until the volume becomes large enough to produce symptoms, by which point the surrounding soil may already be compromised. Camera inspection is the only way to detect the problem before it becomes a foundation issue.

Don’t Just Take Our Word For It
Trenchless Pipe Repair in San Clemente — FAQs
What is pipe bursting and how does it work?
Pipe bursting is a trenchless method that replaces an existing pipe without digging a full trench. A cone-shaped bursting head is pulled through the old pipe — it fractures and displaces the old pipe outward while simultaneously pulling a new HDPE pipe behind it. The result is a new continuous pipe in the same path as the old one, achieved through just two access points at each end rather than an open trench the full length of the run.
Why was the cast iron leaking under the slab in San Clemente?
Cast iron corrodes from the inside out over decades of use. Hydrogen sulfide gas — produced by the bacterial breakdown of waste inside sewer pipes — reacts with moisture to form sulfuric acid that erodes the pipe interior. Most original cast iron laterals from the 1950s–1970s in Southern California are at or past their effective service life. The San Clemente coastal environment accelerates this process.
What is HDPE pipe and why is it used to replace cast iron?
HDPE (high-density polyethylene) is a flexible, corrosion-resistant pipe material used for trenchless sewer replacement. Unlike cast iron or clay, HDPE does not corrode, does not have joints that roots can infiltrate, and maintains smooth interior flow indefinitely. It's the preferred material for pipe burst installations because it can flex through the existing pipe path without cracking.
Do you handle permitting for street sewer work in San Clemente?
Yes — we handle all permitting in-house for street and public right-of-way sewer work in San Clemente, coordinating with the city and the appropriate inspectors for all phases of the work — excavation, pipe installation, and asphalt restoration. You don’t chase the permit office; we own the timeline.
How long does a pipe burst sewer replacement take?
A 45-foot pipe burst like this San Clemente project is typically completed in a single day once access points are open. Camera inspection and access excavation may be done the day prior if scheduling allows. The total project timeline from initial call to completed asphalt restoration is typically 2–3 business days. Call (800) 818-2397 to schedule.
