Don't Wait For A Full Stoppage

7 Signs Your Drain Needs Cleaning

A clogged drain usually gives you warning first. If any of these sound familiar, get it cleared before it turns into standing water or a backup.

  • Water draining slower than usual in a sink or tub
  • A gurgling sound after you run the dishwasher or washing machine
  • Standing water in the shower that takes minutes to clear
  • A faint sour smell coming from the kitchen sink
  • Bubbles rising in the toilet when another drain runs
  • A clog that clears with a plunger but returns within days
  • Slow drainage in more than one bathroom fixture at once

What to expect with our services

Before We Arrive

When you call, we'll ask which fixture is slow, how long it's been happening, and whether it's happened before at that same spot. That tells us what equipment to bring. You'll get a confirmed arrival window and a call if anything changes.

During the Visit

We protect the area around the fixture and run a cable or jetting line to clear the blockage. Once the drain is flowing, we run water for several minutes to confirm it holds, and we'll tell you plainly if we saw anything that suggests a bigger issue underneath.

When We Leave

We clean up any water or debris from the job and walk you through what was actually causing the clog. If it's a habit like grease going down the sink, we'll tell you so you can avoid the next call.

The PlumbSmart Drain Cleaning Approach

Cleared, Not Just Pushed Down

We explain the proposed work and check the repair or installation before leaving. Ask which workmanship and manufacturer warranty terms apply to your quote, including coverage, duration, and the process for reporting a problem. Contact us if something is not working as expected so we can discuss the next step.

The Price We Quote Is The Price You Pay

You'll get a clear price before we start work based on what the drain needs, and we keep you posted if anything changes once we're in the line.

A Slow Drain Is Cheaper To Fix Than A Backup

Most drain problems in San Antonio homes start small: water that takes a little longer to disappear, a faint smell after doing dishes, a gurgle when the washing machine drains. Left alone, buildup keeps narrowing the pipe until the drain stops moving water at all, usually at the worst possible time.

PlumbSmart clears the drain the same day whenever we can, using a cable or jetting line sized to the pipe and the clog. You get a working drain and a plain answer about what caused the slowdown in the first place.

Keep Drains Clear Between Visits

Most clogs build up gradually from the same few habits. A little attention in the kitchen and bathroom goes a long way toward spacing out how often a drain needs professional clearing.

A few habits that make the biggest difference:

  • Let grease cool and throw it out instead of pouring it down the sink
  • Use a hair catcher in the tub or shower drain
  • Run hot water through the kitchen drain after washing greasy dishes
  • Scrape food scraps into the trash before rinsing plates
  • Schedule a cleaning at the first sign of slow drainage, not after it stops completely

I am having a weird issue with intermittent dampness in my garage. Roger spent about 1.5 hours trying to locate the problem. He assured me it was not a plumbing problem and told me not to worry about the service call.

Frequently Asked Questions

How much does drain cleaning cost in San Antonio?+

It depends on which drain is affected and how far the clog sits from the fixture. A single sink clog is usually quick. A main line clear takes more time and equipment. We give you the price before we start, based on what the drain actually needs.

What causes kitchen drains to clog?+

Grease is the main culprit. It goes down as a liquid, cools inside the pipe, and hardens into a coating that catches food particles and eventually chokes the line. Coffee grounds and starchy food scraps make it worse. A cleaning removes the buildup rather than just pushing it further down.

Can I use a store-bought drain cleaner instead?+

We'd steer you away from repeated use. Chemical cleaners can eat into older pipes, and they often clear only part of the clog, so it returns within a week or two. A cable or jetting removes the full blockage instead of dissolving a path through it.

How long does a drain cleaning visit take?+

Most single-fixture clogs are cleared in under an hour. A main drain that's badly blocked, especially if roots are involved, can take longer. We'll give you a real estimate once we've seen the drain, not before.

Why does the same drain keep clogging every few months?+

That usually means the cleaning is clearing a path but not the full pipe, or there's a low spot, a partial pipe issue, or root intrusion collecting debris over and over. If a drain keeps coming back, we'll recommend a camera inspection to find out why instead of cleaning it again and again.

Kitchen sinks and bathroom drains clog for different reasons, and we treat them that way. A kitchen line is almost always grease and food particles hardening on the pipe wall, so we run a cable sized to break through that coating rather than just carve a channel through it. A bathroom drain is usually hair and soap scum caught at the trap or a few feet past it, which clears faster but tends to build back up if nobody uses a hair catcher.

Main drain clogs are a different job entirely. If more than one fixture backs up at the same time, the blockage sits past where the branch lines join, and clearing it takes a longer cable run or hydro jetting depending on what's actually stuck in there.

We've cleared drains in older homes near downtown with narrow cast iron pipes and in newer construction with PVC that clogs for entirely different reasons. The tool changes depending on the pipe and the clog. The goal every time is the same: get the drain flowing and tell you honestly whether it needs anything more than that.
