Drains & sewer
Most single-fixture clogs are cleared with a drain snake in under an hour. If several drains back up at once, or the basement floor drain overflows, the blockage is usually in the main line, which needs a larger machine, a camera inspection or hydro jetting.
One slow drain or the main line?
Where the backup shows up tells you where the clog is:
- One sink or tub is slow: the clog is in that fixture's branch line — usually hair, soap or grease.
- Toilet and tub back up together: the blockage is further down, often where the bathroom lines join.
- Water comes up the basement floor drain when you run the washer or flush upstairs: the main sewer line is blocked. Stop using water and call.
Why Baltimore drains clog
A lot of Baltimore housing was built before 1950. Rowhomes and older suburban houses often still have cast-iron drain stacks and clay (terra cotta) sewer laterals. Cast iron scales and narrows on the inside over decades; clay joints let in tree roots from street trees and mature yards in places like Catonsville, Roland Park and Towson. Grease from kitchen sinks hardens in both.
Hydro jet drain cleaning
Hydro jetting scours the inside of a pipe with a high-pressure water hose. It removes grease, scale and fine roots that a cable only punches through, so it's the usual choice for repeat clogs in a main line or restaurant drains. A good contractor runs a camera first: jetting is not suitable for pipe that is already cracked or collapsed.
Sewer camera inspection before bigger work
If the same line clogs more than once a year, ask for a sewer camera inspection. The video shows roots, sags (bellies), cracks and offset joints, and tells you whether you need cleaning or a sewer line repair. Ask for a copy of the video.
What drain cleaning costs
A standard snake on an accessible fixture drain is usually the cheapest plumbing visit. Main-line clearing, camera work and jetting cost more, and after-hours rates apply in an emergency. Ask for the price per drain or per line before work starts. Our cost guide explains what drives the price.

Frequently asked questions
Are chemical drain cleaners safe for old pipes?
They can damage older cast-iron and galvanized pipe and rarely clear a main-line blockage. A drain snake or plunger is safer for small clogs; call a contractor for anything deeper.
Do I need hydro jetting or just a snake?
A snake clears most single clogs. Hydro jetting is worth it for repeat main-line clogs, heavy grease or fine roots, after a camera shows the pipe is sound.
Can tree roots really get into my sewer line?
Yes. Roots find the joints in older clay and cast-iron laterals. Cleaning removes them for a while; if they keep returning, the line usually needs a repair or liner.
