    How to Tell It's a Main Drain Clog (Not Just One Fixture)

    Multiple fixtures backing up

    Toilet AND tub AND basement floor drain all showing problems = main line.

    Gurgling in other drains

    Flush the toilet, hear the tub/sink gurgle? Air is finding a path around a partial block downstream.

    Sewer smell in basement or yard

    Smell can indicate buildup, broken pipe, or a yard cleanup where sewage has surfaced. Either way, call.

    Water backing up from floor drain

    The lowest opening in the drain system — when the main is blocked, water finds its way up through here first.

    Sewage Coming Up? Stop Using Water.

    No toilets, no showers, no laundry, no dishwasher. Every fixture you use adds to the backup. Call us now for emergency dispatch.

    Main Drain Clog — Common Questions

    How do I know if my main drain is clogged vs just one fixture?
    Multiple fixtures backing up at the same time = main drain. If your toilet, tub, AND basement floor drain are all showing issues, the main line is the problem. A single slow fixture is usually just that fixture. We confirm with a camera inspection before deciding the fix.
    What causes a main drain or sewer line clog?
    The big three on the South Shore: (1) tree roots growing into the pipe through joint separations or cracks — common in older clay or cast-iron sewer laterals; (2) grease buildup from years of kitchen drainage narrowing the pipe; (3) structural damage — a belly, offset joint, or crushed section of pipe. A camera inspection tells us which one we're dealing with.
    How much does clearing a main drain clog cost?
    Our $99 service fee applies toward the work. Main drain cleanings vary based on what we find — a straightforward auger clearing is one price, hydrojetting for heavy grease is another, and finding structural damage that needs repair or spot-dig is a separate quote. We always diagnose with a camera first and give an itemized quote before work starts.
    Is sewer backup an emergency?
    Yes. If sewage is coming up through a floor drain, toilet, or tub, stop using ALL water in the house (no toilets, no showers, no laundry, no dishwasher). Call (617) 479-9911 immediately — we route emergency dispatch. Sewer water is a health issue and prolonged exposure damages flooring, subfloor, and drywall fast.
    Will you need to dig up my yard?
    Not unless we find structural damage to the sewer lateral that can't be cleaned out. Most main drain clogs are clearable with hydrojetting through an existing cleanout. If we DO find damage that requires excavation or trenchless replacement, we show you the video, mark the surface location exactly, and quote the repair work separately.
    How often should a main sewer line be cleaned?
    For homes with mature trees near the lateral, annual or every-other-year preventive cleaning + camera inspection is a good practice. For homes without tree issues, every 3-5 years or when symptoms start. Chronic clogs mean the pipe has bigger issues and needs assessment.
