Sewer Line Repair

Sewer Line Repair & Replacement

We diagnose and repair failing sewer laterals for homes, multi-unit buildings and commercial properties in La Cañada Flintridge, La Crescenta, Montrose, Glendale and Burbank. Licensed, bonded and insured — California CSLB #1027398, with both B (General Building) and C-36 (Plumbing) classifications.

Signs a sewer line is failing

• More than one fixture backing up at the same time
• Water rising in a tub or shower when a toilet is flushed
• Repeat main-line stoppages that return within weeks or months
• Sewage odor indoors or around the yard
• Unusually lush or sunken patches of ground along the line’s path
• Slow drainage throughout the building rather than at one fixture

Diagnosis before excavation

We do not recommend digging based on symptoms. A camera inspection shows the actual condition of the pipe and where the defect is, and locating equipment marks its position and depth. That determines whether the right answer is clearing the line, a spot repair, or replacing a longer section — and it means any excavation is targeted rather than exploratory.

Where the line is still structurally sound but obstructed by roots or heavy scale, hydro jetting may restore it without repair work.

What we find in this area

Older properties across the Crescenta Valley and foothills are frequently still served by clay or cast-iron laterals. Common failure modes are root intrusion at joints, cracked or collapsed sections, offset joints where the ground has shifted, bellies that hold standing water, and corrosion in cast iron. Hillside properties add slope and access considerations that affect how a repair is approached.

Repair options

Depending on what the inspection shows, options generally include clearing and continued monitoring, a spot repair to a defective section, or replacement of the lateral. Trenchless methods can reduce surface disruption where site conditions and the pipe’s condition allow; conventional excavation remains appropriate in other cases. We explain which options apply to your line and why, including permitting where required, rather than presenting a single figure.

Multi-unit and commercial

For buildings where one lateral serves multiple units, a failure affects everyone and access has to be coordinated. See HOA & property management plumbing and preventive maintenance for scheduled monitoring of known problem lines.

Common questions

Can you tell what is wrong without digging? In most cases yes — camera inspection plus locating identifies the defect and its position.

Is trenchless always possible? No. It depends on the pipe’s condition, its route, and site access. We will tell you when it is not suitable.

Is a backup always the sewer line? Not necessarily — single-fixture stoppages are usually local. See drain cleaning.

Do you handle emergencies? Yes — 24/7 emergency plumbing.
