For many homeowners in San Mateo County and Santa Clara County, a failing sewer line is one of the most stressful plumbing problems to face. When backups, foul odors, or slow drains start happening, most people imagine backhoes tearing up driveways, ruined landscaping, and days of disruption.

Fortunately, there’s a smarter, cleaner, and more affordable solution — trenchless sewer line replacement. This modern method lets licensed plumbers replace or repair underground sewer pipes without digging long trenches, preserving your yard, patio, and hardscaping.

At Repipe Champions Plumbing and Rooter Inc., we specialize in trenchless technology throughout the Bay Area, delivering long-lasting sewer solutions to homeowners in San Mateo, Burlingame, Redwood City, Foster City, Santa Clara, Sunnyvale, San Jose, and Mountain View.

What Is Trenchless Sewer Line Replacement?

Trenchless sewer replacement is an advanced plumbing method that allows a damaged or aging sewer line to be repaired or replaced without major excavation. Instead of digging a large open trench from your home to the city main, we access the line through two small entry points, usually at the property line and near your home.

Using specialized equipment, our team installs a new pipe inside or in place of the old one, restoring full function and flow — all in as little as one day.

Why San Mateo and Santa Clara Homes Need Trenchless Solutions

Many homes in San Mateo County and Santa Clara County were built between the 1950s and 1980s, when clay, cast iron, and Orangeburg sewer pipes were the standard. These materials don’t last forever, especially with the region’s clay soils, tree roots, and shifting ground.

Common causes of sewer failure in both counties include:

Cracked or collapsed pipes caused by soil movement
Root intrusion from mature trees like oaks and redwoods
Pipe corrosion from coastal moisture and minerals
Offset joints or broken connections
Constant backups due to internal buildup

If your home is in San Mateo, Redwood City, Menlo Park, or Santa Clara, and you’ve noticed repeated blockages or damp spots in the yard, a trenchless sewer replacement may be the ideal solution.

How the Trenchless Process Works

Trenchless sewer line replacement uses one of two techniques: pipe bursting or pipe lining (also called CIPP – Cured-In-Place Pipe).

1. Pipe Bursting

With pipe bursting, a conical bursting head is pulled through the existing line, breaking the old pipe apart while pulling a new high-density polyethylene (HDPE) pipe into place.

Best for: Severely damaged, collapsed, or undersized lines

Benefits: Creates a completely new, seamless pipe that’s leak-free, corrosion-resistant, and built to last 50+ years.

2. Pipe Lining (CIPP)

Pipe lining involves inserting a resin-coated liner into the old pipe, inflating it, and curing it with steam or hot water. This forms a smooth, durable “pipe within a pipe.”

Best for: Pipes with cracks, corrosion, or root intrusion but still structurally intact

Benefits: Restores the existing line with minimal disruption and extends its lifespan by decades.

Both methods are approved by local building departments in San Mateo County and Santa Clara County, including the cities of San Jose, Palo Alto, Sunnyvale, and Burlingame.

Step-by-Step: What to Expect

Camera Inspection – We perform a detailed camera inspection to locate problem areas and verify the best trenchless method.
Permit Coordination – Our team handles all city and county permit requirements, including lateral compliance programs in San Mateo and surrounding areas.
Access Preparation – Two small pits are excavated to access the beginning and end of the sewer line.
Cleaning and Prep – The old line is thoroughly cleared of debris and roots with hydro-jetting.
Installation – Depending on the damage, we either burst the old line and install new HDPE or insert and cure a CIPP liner.
Inspection – A post-installation camera inspection confirms flow, alignment, and city code compliance.
Restoration – Access pits are backfilled, compacted, and cleaned up — usually the same day.

In most cases, San Mateo County and Santa Clara County projects are completed in one to two days, compared to a week or more for traditional sewer excavation.

The Benefits of Trenchless Sewer Replacement

1. Minimal Yard Damage

Because trenchless methods require only small access pits, your lawn, patio, and driveway remain virtually untouched.

2. Lower Overall Cost

You avoid paying for major landscape and hardscape restoration, which often doubles the cost of traditional sewer replacement.

3. Faster Project Completion

Most projects are finished within a day or two — minimizing disruption to your household.

4. Long-Term Durability

HDPE and CIPP liners resist root intrusion, corrosion, and cracking. Both materials are rated for 50 years or more of service life.

5. Eco-Friendly Solution

Trenchless technology reduces waste, protects trees and soil, and limits the carbon footprint of heavy machinery.

The project took less than eight hours, passed city inspection the same day, and cost 40% less than a traditional excavation.

Another project in Santa Clara involved a cracked cast-iron pipe under a mature oak tree. We installed a CIPP liner to preserve the tree and eliminate leaks — a one-day job that saved thousands in landscape restoration.
