Grease, oils, and fats poured down kitchen drains cool and stick to the pipe wall, catching food and debris until the line narrows or blocks. Hydro jetting scours the grease from the pipe; a camera check confirms the line is clear and undamaged. In Marina del Rey buildings, grease from many kitchens on one shared line is one of the most common problems we fix.
Cooking grease looks harmless when it's hot. In the pipe, it cools, solidifies, and coats the walls. Food scraps, soap residue, and wipes stick to it, and the opening narrows a little at a time. Kitchen lines are affected first, but in a shared building, grease can build up in the main line too. This page is part of our complete guide to sewer line repair in Marina del Rey.
Sewer Grease Blockage Repair: A sewer grease blockage is a buildup of solidified fats, oils, and grease in a drain or sewer line that restricts or stops flow.
A cable machine can punch a hole through a grease clog, but it often leaves most of the grease on the pipe wall, so the clog returns. Hydro jetting uses high-pressure water to scour the wall clean. A camera check afterward confirms the pipe is clear and shows whether any damage is hiding behind the buildup.

Across Marina del Rey's condo and apartment buildings, grease is one of the most common sewer problems we see. A shared kitchen stack collects grease from every unit above it, and it tends to build up where the stack meets the building drain. The first backup usually shows up in a ground-floor kitchen. We hydro jet the stack and building line, camera it to check for damage, and help management set up scheduled jetting. A simple resident reminder about grease disposal, which we're happy to provide in English and Spanish, makes a real difference.
Much of the harbor's residential stock sits on County-owned land under long-term ground leases, which means building management or an HOA is often part of any sewer decision. Tight setbacks and paved common areas leave little room to dig, which is why no-dig methods get serious consideration here. When cleaning or a spot repair will do the job, we say so before quoting anything larger.

Because Marina del Rey isn't inside any city, LA County Public Works handles the permit and inspection for sewer work. Permitted work protects owners and associations at sale, refinance, or insurance review; unpermitted repairs tend to resurface later. If your address turns out to be City of LA, we'll switch the permit to LADBS and tell you before work starts.
Example scenario below is illustrative, based on common situations we see. Details vary by property; not a specific customer.

The Bottom Line
Grease clogs come back when grease stays on the pipe wall. Hydro jetting clears it properly, and a little prevention keeps it from returning.
It moves it further down the line, where it cools and sticks. It doesn’t solve the problem. Grease coats the pipe wall as it cools, narrowing the opening until debris catches. Kitchen lines are the most common location. See our grease buildup page.
Let it cool, then put it in a sealed container in the trash. Hydro jetting cleans the pipe wall properly; cabling just punches a hole through the grease and leaves the buildup for next month.
For sound pipe, yes. We camera first when there’s a question about the pipe’s condition. For multi-unit buildings and restaurants, a scheduled jetting program is far cheaper than emergency clogs. Our multi-unit plumbing page covers the cadence.
It depends on use. For busy shared lines, scheduled jetting is often cheaper than emergency calls. Preventing grease in the drain in the first place is the cheapest fix; solid grease belongs in the trash, not the disposal.
Yes. We can provide a short, bilingual reminder about grease disposal that management can share with residents. For Marina del Rey buildings and restaurants, our scheduled jetting program is the fix; see our multi-unit plumbing page.
