Commercial Sewer Services
A commercial sewer lateral serves everything above it: every restroom, kitchen and floor drain in the building exits through one line. Under commercial load those lines see more grease, more volume and higher stakes; a lateral backup can take an entire property offline.
This section covers sewer services for commercial and multifamily buildings: diagnosis, cleaning coordination, repair and replacement planning, engineered around operations, tenants and the property's compliance file.
Signs You Need This Service
Commercial sewer warnings:
- Backups at the lowest fixtures. Ground-floor and basement drains speak for the lateral, and in commercial buildings they speak for every tenant at once.
- Multiple units or areas affected. Simultaneous trouble across restrooms or units points past branch lines to the shared main.
- Recurring blockages on a schedule. A lateral that clogs quarterly has a condition, not bad luck: grease, roots, or a defect the camera will name.
- Odors in common areas. Venting, trap or line-condition issues that tenants report before managers see water.
- Wet ground or settlement over the lateral. Exfiltration undermining soil: a structural warning worth immediate diagnosis.

Service Details & What's Included
The work this section covers:
- Inspection. Camera surveys with located, documented findings, for problems, due diligence and pre-purchase.
- Cleaning programs. Scheduled jetting for grease- and root-prone laterals, coordinated with the drain programs under Commercial Drain Cleaning.
- Repair and replacement. Spot repairs, lining and bursting where conditions allow, excavation where they do not, scoped with tenant impact and restoration stated up front.
- Multifamily service. Shared-lateral realities of apartment and condo properties: stack-to-lateral diagnosis and association-friendly documentation.
Frequently Asked Questions
Is the blockage in our building sewer or the municipal main?
The camera answers it with a footage marker: findings up to the property boundary or tap are the owner's; beyond is the city's. Surcharge events (water rising without a blockage) point municipal, and the utility should hear about them either way.
When is camera inspection worth it for a commercial line?
On any recurring blockage, before any repair decision, at purchase, and after cleaning heavy buildup: the inspection converts sewer problems from anecdotes into located, budgetable facts.
Should the line be cleaned before inspecting?
When buildup obscures the walls, yes: jet first, inspect clean pipe. Judging a greased-over line risks either missing defects or inventing them; the clean-then-look order protects the budget both ways.
Which defects actually require repair?
Structural ones: breaks, collapses, significant offsets and bellies that trap flow, and root entry through failed joints. Buildup alone is a cleaning program; the camera report should separate the two in writing.
Can sewer work happen without shutting the building down?
Mostly yes: trenchless methods, sectional isolation, bypass setups and night work exist precisely for occupied properties. Where a full outage is unavoidable, the plan states the window and the tenant-notice lead time.
