Drain cleaning
Drain cleaning clears clogs from sinks, tubs, showers, toilets and the main line with a drain snake (auger) or high-pressure water jetting. If several drains are slow at once, the problem is usually the main line, not the fixture.

Kitchen drains clog with grease, food and soap that harden in the pipe. Bathroom drains clog with hair and soap scum. When a toilet gurgles as the tub drains, or water backs up in the lowest drain in the house, the blockage is further down, in the main line.
A plumber clears the line and can run a camera to see what caused it: buildup, a belly (sag) in the pipe, or tree roots. Roots and broken pipe keep coming back after cleaning; see sewer line repair.

Process
What the crew does
- 1
Find the blockage
The plumber checks which fixtures are affected to tell a local clog from a main line problem.
- 2
Clear it
A hand or machine auger breaks up the clog, or hydro-jetting scours buildup from the pipe walls.
- 3
Camera check
For repeat or main line clogs, a camera inspection shows roots, breaks or sagging pipe.
- 4
Prevent a repeat
You'll get advice on what's causing the clog, and options if the pipe itself needs repair.

Full system repressurization, leak check under working pressure, cleanup, and warranty walkthrough.
Cost
What affects the price
Every job is scoped on site. These are the factors that move the number.
- A single fixture versus the main line
- Access: a cleanout outside versus pulling a toilet
- Snaking versus hydro-jetting
- Whether a camera inspection is needed
- After-hours timing

FAQ
Drain Cleaning questions
What is professional drain cleaning?
Professional drain cleaning clears blockages and strips organic buildup from interior drainpipes, traps, and main building drains using motorized mechanical snakes, drum augers, or high-pressure hydro-jetters.
When is professional drain cleaning needed instead of a simple plunger?
Professional cleaning is necessary when standing water fails to clear after plunging, when multiple fixtures drain sluggishly at the same time, when sewage backs up into shower pans, or when foul odors persist from drain openings.
What are the common warning signs of a developing drain clog?
Warning signs include water swirling slowly, gurgling or bubbling sounds from toilet bowls when sinks drain, laundry discharge backing up into utility tubs, and recurring fruit flies or drain gnats around kitchen traps.
How does a professional drain cleaning process work?
The plumber assesses the affected fixtures, selects an appropriate entry cleanout, inserts a motorized cable with specialized cutting blades to break up the obstruction, flushes the line with water, and optionally performs a fiber-optic camera inspection to verify clear pipe walls.
What factors determine drain cleaning pricing?
Pricing depends on whether the clog is localized to a secondary fixture line (sink or tub) versus the building main sewer drain, access point convenience (outdoor ground-level cleanout versus pulling a toilet or roof vent access), and whether mechanical snaking or hydro-jetting is required.
How long does a drain cleaning service call take?
Clearing a single sink or shower trap typically takes 30 to 60 minutes. Clearing a main line through an outside cleanout and running a follow-up camera inspection usually takes 1 to 2 hours.
What should homeowners do before the drain technician arrives?
Stop running water in all sinks, tubs, and washing machines. Clear items from under the sink vanity or around the floor cleanout, and notify the plumber if you poured chemical drain cleaners into the line to protect them from chemical burns.
What should I do if a drain clog causes standing wastewater to overflow?
Immediately cease water usage throughout the home. Place old towels around the fixture base to contain moisture, avoid skin contact with contaminated wastewater, and open windows for ventilation.
What is the difference between cabling (snaking) and hydro-jetting?
A mechanical snake punches a hole through a dense clog to get water flowing, making it effective for hair, wipes, and immediate blockages. Hydro-jetting uses 3,000+ PSI water streams to scour grease, mineral scale, and root hairs entirely off pipe walls, providing a longer-lasting clean.
What should I ask a drain cleaning company before booking?
Ask whether their quote covers a standard cable length (such as up to 75 or 100 feet), whether a video camera inspection is included or available, and what warranty period they provide against recurring clogs.
