About Pomona Trenchless
Sewer lateral repair specialists in Pomona, CA. Camera inspection first. Written estimates. Licensed contractors.
What does Pomona Trenchless do and who do we serve?
Pomona Trenchless diagnoses, repairs, and replaces sewer laterals for residential properties in Pomona and the surrounding San Gabriel Valley communities including La Verne, Claremont, Ontario, Chino, Diamond Bar, and Walnut. Our work covers the full scope of residential sewer lateral problems: Orangeburg pipe at or past its service life, clay pipe with root intrusion or cracked joints, cast iron pipe with corrosion and significant blockage, and any lateral that needs assessment before a homeowner makes a repair decision.
Pipe Lining (CIPP)
For pipes cracked or with joint damage that still hold their shape. A resin liner installs from the inside — no excavation. One-day completion for most Pomona residential laterals.
Pipe Bursting
For collapsed or severely damaged pipes. A new HDPE pipe replaces the original completely via two small access pits. The permanent solution for pipes too deteriorated to be lined.
Sewer Camera Inspection
The starting point for every job. Live footage, locations marked above ground, copy of the recording provided to you before we discuss any repair option or quote.
Hydro Jetting
High-pressure water cleaning for root mass, grease accumulation, and debris. Performed before lining or as standalone maintenance on sound pipe with recurring blockage.
Why does Pomona sewer work require specific local knowledge?
Pomona has a higher concentration of original Orangeburg sewer laterals than most cities in the LA east region. A large proportion of homes built here between 1945 and 1972 still have the original tar-and-wood-fibre pipe — now 55 to 80 years past installation. Diagnosing Orangeburg failure correctly, determining whether lining is still viable or full replacement is required, and executing the correct trenchless method for each property’s specific soil conditions and pipe depth requires direct experience with this material and this specific city. We understand Pomona’s soil profile variation across different neighbourhoods, the typical lateral depths for properties with different setback distances, the permit requirements at the City of Pomona Building and Safety Division, and the connection protocols at the city’s sewer main under the street.
How does Pomona Trenchless handle licensing and permits?
| Our Standard | What This Means For You |
|---|---|
| C-42 / C-34 licensed contractors | All sewer lateral work performed by or supervised by a licensed contractor. Verify any license at cslb.ca.gov before authorising work with any contractor. |
| Camera inspection first on every job | We show you the footage before recommending any repair method. No verbal assessments, no guesswork — you see the inside of your pipe before any discussion of repair options. |
| Permits pulled before work begins | We do not begin any repair or replacement work without the required City of Pomona permit in place. The permit record protects your property title when you sell. |
| Written itemised estimates | Method, linear footage, pipe material, permit status, and post-installation verification — all specified in writing before you sign. No single-line quotes. |
| No same-day repair pressure | We do not ask for a repair decision on the day of the camera inspection. You receive the footage, take time to consider the estimate, and make a decision on your own timeline. |
| Post-installation camera confirmation | Every lining and bursting job concludes with a final camera inspection confirming the repair is complete and the pipe is flowing correctly before we consider the job done. |

What should Pomona homeowners know before calling a sewer contractor?
The sewer lateral — the private pipe running from your foundation to the city main under the street — is entirely your responsibility as a Pomona homeowner. The city owns the main sewer line; you own the lateral. Every aspect of inspection, repair, and replacement costs falls on the property owner. Before calling any contractor, know your home’s build year — if it was built before 1972, there is a meaningful probability your lateral is still original Orangeburg pipe. Know whether the property has an accessible cleanout — if not, the first part of any inspection will involve either removing a toilet or installing a cleanout. And know that no contractor should recommend a repair method without first showing you the camera footage from inside your specific pipe. A camera inspection is always the correct first step.
Frequently Asked Questions — About Pomona Trenchless
Yes. Every job starts with a camera inspection. After the inspection, we provide a written, itemised estimate specifying the repair method, linear footage, pipe material, permit status, and post-installation verification. We do not ask for a decision on the same day as the inspection.
All sewer lateral work is performed by or under the direct supervision of contractors holding a current C-42 Sanitation Systems or C-34 Pipeline licence from the California Contractors State License Board. You can verify any licence at cslb.ca.gov before authorising any work.
Yes. All structural sewer lateral work — pipe lining, pipe bursting, and open-cut replacement — requires a permit from the relevant city Building and Safety Division. We pull all required permits before work begins. We do not start any structural repair without the permit in place.
