βRomero Bros showed up the same day to check out my job and give me an estimate. They were cheaper and faster than the other company I had been talking to. They were back the next morning and got everything, and more, repaired. Vicente went the extra mile and covered a few other small things while they were there. I will definitely be using them and Vicente for my future needs!β

Know the warning signs
Signs You Need
Drain Cleaning
Slow-draining sinks, tubs, or showers
Water that takes longer and longer to leave a fixture usually means something is building up inside the drain.
Standing water
Water that sits in a sink, tub, or shower after you use it points to a blockage that is not clearing on its own.
Gurgling or bubbling sounds
Gurgling from a drain or toilet can be a sign that water and air are not moving through the line the way they should.
Odors coming from drains
A persistent bad smell from a drain can come from buildup in the line and is worth having looked at.
A toilet that will not clear
An occasional clog can happen. A toilet that keeps clogging, or clogs along with other fixtures, deserves a closer look.
Clogs that keep coming back
Recurring clogs, or several fixtures draining slowly at once, can point to a larger drainage problem rather than a one-time blockage.
Not sure what is going on with your drain? Call us or send a service request and Romero Bros will take a look.
Know the difference
Routine Clog Or
Urgent Backup?
A Routine Drain Problem
One fixture is slow or clogged, such as a kitchen sink, bathroom sink, or shower, and the rest of the house drains normally. Romero Bros can clear the blockage and explain what likely caused it.
An Urgent Sewage Backup
Wastewater is coming up through floor drains, tubs, or toilets, or more than one fixture is backing up at the same time. Avoid contact with the water, stop using fixtures, and call (626) 826-7743 right away.
If a clog returns after you clear it yourself, or you are not sure which category you are in, call and describe what you are seeing. Romero Bros will help you figure out the next step.

Questions
Drain Cleaning
Questions
What causes a drain to clog?
Clogs commonly build up from hair, soap, grease, food, and other debris collecting inside the drain over time. A toilet can clog when something that should not be flushed gets stuck. The cause depends on the fixture and the line.
When should I call a plumber instead of clearing a clog myself?
Consider calling when a clog keeps coming back, when more than one fixture is draining slowly, or when water is backing up. Those can point to a problem deeper in the line than a simple blockage.
What is the difference between a clogged drain and a sewage backup?
A clogged drain usually affects one fixture. A sewage backup means wastewater is coming up through floor drains, tubs, or toilets, often in more than one place. A backup is more urgent: avoid contact with the water, stop using fixtures, and call (626) 826-7743.
Can you help with a toilet or main drain blockage?
Call (626) 826-7743 and describe what is happening. Romero Bros will talk through the situation with you and explain the next step.
Can you fix a drain that keeps clogging?
Recurring clogs can mean there is more going on than a single blockage. Romero Bros can look at the situation and explain your options, so the recommendation fits your actual plumbing.
Do you offer same-day or emergency drain service?
Call (626) 826-7743 to talk about your situation and ask about availability. Availability depends on scheduling.
