Drain Cleaning Services in San Antonio
Water backing up into sinks, tubs, or showers is usually a sign that something is restricting flow inside your drain system. Drain odors, gurgling sounds, and slow drainage often indicate buildup inside the pipes. Every drain in your home is susceptible to clogs over time, even with careful use.
Soap residue, hair, grease, mineral deposits, and everyday waste gradually collect along pipe walls. While surface-level clogs may respond to plungers or drain covers, deeper or recurring blockages often require professional drain cleaning to fully clear the line.
What Causes Drain Clogs?
Many drain clogs develop slowly. Items that don’t fully break down can remain inside pipes and accumulate over time. Household drain pipes are typically around four inches in diameter, which allows debris to collect without immediately stopping flow.
Common causes of drain clogs include grease buildup, hair, hygiene products, soap residue, and mineral scale from hard water. Tree roots can also enter underground lines through small joints or cracks. Even responsible use can eventually lead to restricted drainage.
Signs You May Have a Clogged Drain
Some drain clogs are obvious, while others develop deeper in the system. Ignoring early warning signs can allow a small blockage to turn into a larger issue. Common signs of drain problems include:
- Slow draining sinks, tubs, or showers
- Gurgling sounds from drains or toilets
- Water or sewage backing up from drains
- Moisture or leaking around toilet bases
- Persistent drain odors
If more than one fixture is affected or a toilet is involved, the issue may be in a larger drain line rather than a single fixture drain.
Professional Drain Cleaning
Store-bought drain cleaners are often ineffective against serious blockages and can damage pipes with repeated use. Chemical products may clear surface buildup but typically don’t remove the underlying cause of the clog.
Professional drain cleaning uses mechanical and water-based methods to remove buildup safely and restore flow. Our plumbers assess the location and severity of the clog before selecting the appropriate cleaning method. You’ll receive an explanation of the issue and an estimate before any work begins.
Types of Drain Cleaning Methods
Hydro Jetting Drain Cleaning
Hydro jetting uses high-pressure water to break up heavy buildup and thoroughly clean the inside of drain pipes. This method is effective for grease, sludge, and recurring clogs in larger lines.
Manual Snake or Auger Cleaning
Drain snakes and augers use a flexible cable to scrape and remove blockages from inside the pipe. This method is commonly used for smaller drains and localized clogs.
Motorized Snake Cleaning
Motorized equipment provides added power to clear tougher obstructions and longer drain lines. This option is often used when manual methods aren’t sufficient.

Drain Cleaning FAQs
When do I need a drain inspection instead of a cleaning?
If clogs keep coming back, multiple fixtures are affected, or a toilet is backing up, an inspection may be needed to identify what’s happening inside the pipe. Camera inspections help locate buildup, roots, or damaged sections that basic cleaning may not resolve.
What’s the difference between drain cleaning and drain repair?
Drain cleaning removes buildup and blockages inside the pipe to restore flow. Drain repair addresses physical damage to the pipe itself, such as cracks, corrosion, or collapse. Cleaning is often the first step, while repairs are recommended when structural issues are found.
How long do drain pipes usually last?
The lifespan of drain piping depends on material and usage. Many older sewer and drain lines last 50–60 years, while newer PVC systems may last longer. Regular cleaning and inspections can help identify issues early and extend system life.
