Bathroom drain
clogged?

A backed-up tub, shower, sink, or toilet is an unwelcome surprise, and we make fixing it as painless as we can. Most bathroom drains are simply clogged with hair and soap scum, which a cable usually clears. If the same drain keeps clogging, we find out why and fix the cause. We offer same-day service for most non-urgent jobs booked before noon.

Common bathroom clogs

Common bathroom drain clogs and how we clear them.

  • Shower/tub drain (slow): Hair, soap scum, conditioner buildup. Usually cleared with a cable.
  • Bathroom sink: Hair, toothpaste, makeup. Often the trap; sometimes the branch line.
  • Toilet won't flush: Could be the toilet itself (foreign object) or the line beyond it. We diagnose first.
  • Several bathroom drains slow at once: A sign of a branch line or main line clog, not individual fixtures.
