Restaurant grease lines, floor drains, apartment stacks and building sewers, cleared when they stop and kept on a schedule so they do not. Flat quotes, camera proof, and a work window that fits around your service.
Seven days, 8 AM to 8 PM · Flat quote per line or per schedule

The short answer
Commercial drain cleaning keeps restaurant grease lines, floor drains, apartment stacks and building sewers flowing, on a call or on a schedule. In Seattle, businesses with commercial kitchen plumbing need a grease interceptor and must clean it when it is 25 percent full; we clear and jet the lines around it. Pricing is a flat quote per line or per scheduled visit.

Downtime is the real cost of a commercial clog, so the work is built around getting you open and keeping you open.
We clear the line that stopped, camera it so you know why, and if it is grease or buildup, set a jetting schedule that matches your volume instead of waiting for the next backup.
For single drains in an office or retail space, standard drain cleaning pricing applies. Kitchen grease lines, multi-unit stacks and building sewers are quoted per line or per scheduled visit, in writing, before work starts.
Different buildings fail in different places. This is where we usually start.

Every job is quoted flat before work starts. Ask about a maintenance schedule for any line we clear twice.
Grease is regulated in Seattle. These rules come straight from Seattle Public Utilities and the municipal code.
SPU says any business with commercial kitchen plumbing fixtures and a King County Food Business Permit must install a grease interceptor, including delis, coffee shops, pizza places and caterers. SPU: Commercial kitchens
Businesses must clean interceptors per the manufacturer’s specifications, or when they are more than 25 percent full of grease and food waste, under SMC 21.16.310. SPU: Commercial kitchens
SMC 21.16.310 bars emulsifying agents, enzymes, bio-additives and similar chemicals in interceptors. SMC 21.16
SPU says non-compliance can bring penalties from $250 to $5,000, plus the City’s costs for damage caused by grease-laden wastewater. SPU: Commercial kitchens
SPU says a business with a backup should close immediately and contact Seattle-King County Public Health for direction. SPU: Commercial kitchens

Floor drains, grease lines and building sewers get the same camera-first approach as a house, with bigger equipment.
When a line is down, the first job is getting you back in service: cable or jetter, whichever reopens it fastest.
The camera shows grease, a belly or a problem unit on a shared stack, so the fix is aimed at the cause.
A jetting schedule set by what came out of the line, not a guess, and records for your files.




Most businesses start with a call. The ones that clog twice usually save money on a schedule.
| What to check | On-call clearing | Scheduled maintenance |
|---|---|---|
| When we come | After the line stops | Before it stops, at a time you pick |
| Downtime | Whatever the backup costs you | Planned around your service |
| Method | Cable or jetter to reopen | Jetting to keep the wall clean, camera as needed |
| Records | Invoice for the visit | Visit notes and footage over time |
| Price | Flat quote per call | Flat quote per scheduled visit |

We work 8 AM to 8 PM, seven days a week, so most scheduled cleanings can be set before service, between lunch and dinner, or on a slower day. Tell us your hours and we will book around them.
It depends on volume and menu. The camera and what comes out of the line on the first visit set the schedule; busy fryer-heavy kitchens need it more often than a coffee shop. SPU’s best practices, like scraping dishes before washing, stretch the interval.
We clear and jet the drain lines that feed the interceptor and the line leaving it. Ask us about the interceptor itself when you call, and we will tell you what we handle and what goes to a grease hauler.
