New Lateral Connections

This service is provided when the contractor needs a new lateral from the sewer mainline to the property line. As this service is a key part of many projects our team is highly experienced in lateral connections.

Septic Tank Abandonment

We offer septic tank abandonment services. We may backfill with slurry, compacted soil, or other approved materials when abandoning the septic tank.

Lateral Replacement

Often times, inspectors will CCTV the sewer lateral before allowing our customers to use existing house connections on new projects. If the inspector does not pass that lateral and needs it replaced, we can use the existing wye at the mainline and run a new lateral for our customers.

Trenchless Line Replacement

Advances in technology have changed the processes for replacements and enable us to provide more durable solutions. This style of replacement is less invasive, making it easier to preserve the landscape and other surrounding elements of the property.

Spot & Line Repair

When a video inspection reveals an easily localized blockage or collapse, our bonded sewer contractors in Los Angeles can isolate the compromised section and repair it with minimal invasiveness. Call us for information about spot repair options.

Grease Interceptors

From new installation to removal or maintenance of existing grease interceptors, our bonded sewer contractors offer several grease trap and interceptor solutions for both residential and commercial properties in Los Angeles, California.
