Drain Cleaning in San Antonio, TX

Slow drains, gurgling pipes, or a full clog? Alamo City Waterworks clears drains at the source for San Antonio homes and businesses, not just the surface symptom.

The Real Problem

A Slow Drain Is Rarely "No Big Deal"

A drain that empties slowly or gurgles is usually a sign of a partial blockage building up somewhere in the line. Ignoring it just gives the clog more time to grow.

Store-bought drain chemicals can mask the symptom for a little while, but they rarely clear what is actually causing the backup, and repeated use can damage older pipes.

How We Clear a Drain the Right Way

We find where the clog actually is instead of guessing, then clear it at the source using the right tools for that specific drain. If we spot a bigger issue while we're in there, like a cracked pipe, we'll tell you before doing anything extra.

Drain Cleaning Questions

What causes slow or clogged drains?

Grease, soap buildup, hair, food debris, and mineral scale are the most common causes. Tree roots and older, narrower pipes can also contribute, especially further down the line.

Are drain cleaning chemicals bad for my pipes?

Repeated use of harsh drain chemicals can damage older pipes and seals over time, and they often only clear part of the blockage. A mechanical clearing gets to the actual clog without the chemical exposure.

Can you clear a main sewer line clog too?

Yes. If a clog is deeper in your main line rather than a single fixture drain, that falls under our sewer line repair service, and we can tell you which one you’re actually dealing with.

How do I know if it's a drain clog or a bigger sewer line problem?

If just one fixture is slow, it's usually a local clog. If multiple drains back up at once or you notice sewage smells, that often points to the main line, and we'll check both when we come out.

Do you clean both kitchen and bathroom drains?

Yes, we clear kitchen sinks, bathroom sinks, tubs, showers, and toilets.

Do you handle drain cleaning for commercial kitchens and businesses?

Yes, we service drains for San Antonio businesses as well as homes, including commercial kitchen lines.
