When to call a plumber
DIY clears most single-fixture clogs. These signs mean it’s time to put the plunger down and get a pro — you’ll save money versus making it worse.
Call now if…
- More than one drain is backing up Toilet + shower, or both kitchen sinks, or water rising in the tub when you run the washing machine. That’s often a main sewer line or a shared stack — not a local hair clog.
- Sewage smell or sewage on the floor Don’t keep flushing. Limit water use in the house and call. Avoid standing in contaminated water without boots.
- Water won’t go down after solid DIY You’ve plunged correctly, snaked what you can reach, and cleaned the trap — still blocked. Deeper clogs need a real auger or camera.
- You hear gurgling in other fixtures Gurgling toilets when the sink drains (or the reverse) often means vent or main-line trouble.
- Old / fragile pipes, or a rental with rules Cast iron, polybutylene, or a landlord who wants licensed work only — don’t force a metal snake through guesswork.
- Chemical cleaner already failed Tell the plumber what you poured in. Don’t add a second product on top.
Before they arrive
Note which fixtures fail, when it started, and what you already tried. Clear stuff from under the sink. If it’s a toilet overflow risk, know where the shutoff valve is (behind the bowl).
Cost reality check
A simple clog clear is often far cheaper than water damage from overnight overflows or a DIY mistake that cracks a trap. Emergency after-hours rates cost more — if it’s not flooding, morning may be fine.
Still worth DIY first
One slow shower, one bathroom sink, or one toilet that responds to a good plunging session — start with the guides:
