Drain Cleaning in San Antonio, TX
A slow sink or backed-up shower should not take over your day. Get help clearing the blockage and understanding what caused it.
Five Star Plumbing helps homeowners in San Antonio, Castroville, and the surrounding area with kitchen, bathroom, and main-line drain clogs. Tell us which fixtures are affected and whether the problem has happened before so we can plan the next step.
One slow drain or several backed-up fixtures?
A clog at one sink or tub may be close to that fixture. When several fixtures drain slowly or water comes up in another drain, the obstruction may be farther down a shared line. The symptoms help guide an inspection, but they do not identify the cause on their own.
- Kitchen sinks that hold water after dishes
- Showers or tubs that empty slowly
- Toilets that gurgle when another fixture drains
- Backups that return soon after a drain is cleared

How we approach drain cleaning
We start by discussing the symptoms and checking accessible fixtures and drain access points. The appropriate cleaning method depends on the blockage, pipe condition, and access; a plumbing cable or hydro jetting may be considered after that assessment.
Once the blockage is addressed, we check drainage and explain any signs that need further investigation. If clogs keep returning, a sewer camera inspection can help identify a cause that cleaning alone may not resolve.
Before your drain service visit
If wastewater is backing up, stop using the affected fixtures and call for service. Let us know about any drain-cleaning products already used. Keep the area around the affected fixture or accessible cleanout clear so the plumber can work.
A recurring clog calls for a different conversation than a first-time slow drain. Visit our recurring drain clogs page for help describing the pattern.

Recurring Drain Clogs
When the same drain keeps backing up, another quick clearing may leave the underlying problem unresolved.
Sewer Camera Inspection
See what an accessible sewer line can reveal before deciding on cleaning, repair, or replacement.
Sewer Line Repair
A damaged section of sewer pipe may call for a targeted repair. Start with an assessment of the problem and the rest of the line.
Sewer Line Replacement
When a sewer line has extensive damage, plan a replacement with a clear understanding of the scope and disruption.
Tree Roots in Sewer Line
Clearing roots can restore flow, but understanding how they entered the pipe matters for the next step.
Drain Cleaning: Common Questions
Do you clean kitchen and bathroom drains?
Yes. We service household drains, including sinks, tubs, showers, and main drain lines. The method depends on the location and condition of the blockage.
Does every drain cleaning need a camera inspection?
No. A camera inspection may be useful for repeated blockages or a suspected main-line issue. We can discuss whether it would help with your specific symptoms.
How much does drain cleaning cost?
Cost depends on access, the location of the clog, and the work needed to clear it. Contact us to discuss your symptoms and request an estimate.
What if the drain clogs again?
Tell us how soon the clog returned and which fixtures are affected. Further inspection may be needed to check for remaining buildup, roots, or a damaged section of pipe.
