Why Do My Drains Keep Clogging?

Clearing a clog with a store-bought snake or a bottle of drain cleaner often feels like a fix — until the same drain slows down again a few weeks later. If that’s a pattern for you, something deeper than a one-time clog is going on.

What builds up over time

• Grease. It goes down as a liquid but hardens as it cools, coating the inside of the pipe and catching everything that follows.
• Hair & soap. The classic bathroom combination — they bind together and slowly narrow the pipe.
• Mineral scale. Hard water leaves deposits inside pipes that reduce their effective width over years.
• Roots. In sewer lines, roots seeking moisture grow into small cracks and joints, eventually blocking flow.

Why clearing it doesn’t always fix it

A standard snake punches a hole through a clog rather than removing what’s coating the pipe walls. That’s often enough for a while, but the buildup left behind gives the next clog a head start. This is especially true for older or long-neglected lines.

When it’s a sign of something bigger

If a single drain clogs repeatedly, it’s likely local buildup — the fix is usually a proper cleaning, not a repeat snaking. But if multiple drains slow down together, or a fixture gurgles when another one drains, that points to the main sewer line, not an individual drain. That’s a different problem with a different fix.

What actually breaks the cycle

• Hydro jetting uses high-pressure water to strip buildup from the pipe walls rather than just punching through it.
• A camera inspection shows exactly what’s inside the line — buildup, roots, a belly, or a break — so the fix matches the real cause.
• Prevention habits — keeping grease out of drains, using a hair catcher, and being mindful of what’s flushed — slow the buildup that causes clogs in the first place.
