Drain and Sewer Work, Start to Finish

Drain and sewer problems in Gaithersburg split into two very different jobs, and knowing which one you have changes the price completely. A single slow fixture is a local clog you can often reach with a cable in under an hour. Two or more fixtures backing up at once means the main line is blocked, and the lowest drain in the house floods first. Describe which it is at [(301) 834-2944](tel:+13018342944) and you'll get a real read before anyone drives out.

Chase runs a camera down the line before deciding on a method. That isn't a sales step; a cable clears a hair mat fine and wastes money on a root mass, while jetting a line that a cable would have handled is exactly the upsell nobody should be paying for.

Pick the Job You Actually Have

Details below

Slow or blocked single drain

One sink, tub, or shower. Usually a hair-and-soap mat just past the trap. Clogged drain removal.

Routine drain cleaning

Kitchen and bath lines that have been getting slower for months rather than failing outright. Drain cleaning.

Main line backing up

Multiple fixtures at once, gurgling when you flush, water at the floor drain. Sewer line cleaning.

Grease or scale-coated pipe

Recurring kitchen clogs where cabling gets it draining and it closes again weeks later. Hydro jetting.

Why Older Neighborhoods Get Root Intrusion

Root intrusion isn't random. It follows old pipe joints, and much of the housing around Gaithersburg, Rockville, and Kensington was built when clay and cast iron were standard for sewer laterals. Roots find the joint, get in as hairs, and thicken until the line closes. A cable will punch a hole through the mass and get you draining again, which is why people think it's fixed and then call back the next season.

Camera first, then choose. If the line is structurally fine and the problem is what's inside it, jetting clears the wall of the pipe rather than boring a channel through the blockage. If the pipe itself has failed, no amount of cleaning is the answer and we'll say so instead of selling you an annual cabling subscription.

What Doesn't Belong Down a Drain

Wipes labelled flushable are the single most common cause of the main-line clogs we pull. They don't break down the way paper does; they bind together and catch on any joint or bend. Grease is second, and it doesn't harden at the sink, it hardens further down where the pipe is cold.

Skip caustic drain cleaner entirely. It rarely moves a solid clog, it works on your pipes and seals while it sits in the trap, and it makes the line dangerous for whoever cables it after you.

FAQ Common questions

Frequently Asked Questions

Answers below
How do I know if it's one drain or my main line? +
Run water in a different fixture. If only one drain is slow and everything else behaves, it's local. If flushing a toilet makes the tub gurgle or back up, or if the lowest drain in the house floods, the blockage is in the main line and needs the line cleared rather than a fixture snaked.
Is hydro jetting better than snaking? +
It's better for the right problem, not universally. A cable is the right tool for a hair mat or a single obstruction. Jetting is what you want when the pipe wall is coated with grease or scale, or when roots need cutting back rather than punching through. That's why the camera goes in first.
Will roots come back after you clear them? +
If the pipe joint they entered through is still open, yes, eventually. Clearing buys time and tells you the real condition of the line. When the camera shows a failed section rather than a clean pipe with roots in it, cleaning is the wrong fix and we'll tell you that.
Do you clear outside and underground lines too? +
Yes, including work that needs digging. See water line repair for underground supply and lateral repairs, which sometimes follow a camera inspection that finds a broken section rather than a blockage.
