A slow drain is annoying; a fully blocked main line is an emergency that can back sewage into your home. Drain cleaning is one of the highest-volume plumbing searches because almost every homeowner faces it eventually. Costs range from $150 for a simple sink clog to $500+ for main-line hydro jetting — and knowing which one you need before the plumber arrives saves real money.
What actually clears a clog
Plungers and drain snakes handle most fixture clogs. Chemical drain cleaners mostly do not work on real blockages and can damage pipes — our guides explain what to try in what order, and the point where DIY ends and a pro with a camera and jetter begins.
Recurring clogs mean something bigger
If the same drain clogs every few months, the problem is usually in the line itself: root intrusion, a belly (sagging section), or scale buildup. That is a sewer-line issue, not a drain-cleaning issue — see our sewer line guides before paying for your third cleaning.
