Drain Cleaning Services
Drain Cleaning Services in Marin, Sonoma & Napa County
Clogged drains are more than just an inconvenience, they can disrupt your day, damage your plumbing system, and even lead to water damage or costly repairs if left unresolved.
You can try clearing your drain with a plunger or other DIY remedies that may or may not work, or call us at Ongaro & Sons for quality work and ensured success. We offer professional drain cleaning services throughout Marin, Sonoma, and Napa counties.
Our experts safely clear blockages and restore normal water flow in residential plumbing systems. With since 1932 of experience and a team of licensed plumbers, we’re the North Bay’s trusted source for fast, effective solutions to drain problems of all sizes.
Drain Cleaning and Clog Busting Options
Our Ongaro & Sons plumbers will assess the problem and recommend the best solution for your plumbing system. The techniques we use are designed specifically for the size and location of the clog. We typically remove clogs that form in your bathroom, kitchen, and floor drains with a drain-cleaning cable machine, though we can use hydro jetting methods when necessary.
Drain Maintenance You Can Do at Home
We recommend leaving drain and sewer line cleaning and flushing to professionals, like our experts at Ongaro & Sons. However, you can help keep your plumbing in top shape by treating it with a little TLC.
Here are some ways you can avoid clogging your drains and sewer line:
Only Flush Toilet Paper
Only flush toilet paper down your toilet, avoid flushing wipes, feminine hygiene products, paper towels, or anything labeled “flushable.” These items can clog pipes, damage plumbing, and lead to costly backups or sewer line issues.
No Grease Down the Drain
Dispose of oil or grease in the trash, not down your sink drain. After leftover cooking oil cools slightly, pour it into a disposable container to harden before tossing it into the garbage.
Use a Drain Screen
Use a drain screen across all the drains in your home. Add one to your sink to prevent food particles from clogging your drain, and another to catch hair before it goes down the shower drain. Attach a metal mesh lint catcher to your washing machine’s discharge hose, and consider placing a drain screen or lint trap in the laundry sink drain hole.
Use Natural Drain Cleaners
Pour enzyme-based drain cleaners into your plumbing system periodically to keep clogs from forming. These drain cleaners work best as a preventative measure and remove only organic materials. They are easier on your pipes than chemical drain cleaners. To further protect your drains and pipes, use a vinegar-baking soda combo to clean them periodically.
When to Call for Drain Cleaning
Common signs you need professional drain cleaning include:
- Water draining slowly from sinks, tubs, or showers.
- Gurgling sounds coming from your drains.
- Recurring clogs, even after trying to clear them.
- Unpleasant odors caused by buildup in your pipes.
- Standing water around floor drains or fixtures.
If you’re noticing any of these red flags, don’t wait. Our experts will diagnose the issue and get your drains flowing smoothly again, without causing damage to your plumbing system.

Prevent Clogs With Regular Maintenance
You don’t have to wait until a clog causes a toilet or drain backup to call Ongaro & Sons for help. We recommend regular drain cleaning and sewer line maintenance to prevent waste buildup and clogs.
Schedule periodic drain cleanings to keep water flowing in your sinks, toilet, and shower. Consider inspecting your sewer line every few years, especially if large trees grow on your property. We can identify emerging problems, such as root growth, by snaking a camera through the sewer line.

Why Ongaro & Sons for Drain Cleaning
A drain that blocks repeatedly is telling you something a cable will not fix.
Schedule Service →Repeat blockages get investigated, not just cleared
If the same drain blocks twice, a camera tells you whether there is a defect, a belly or root intrusion behind it.
The right tool for the blockage
Cabling and jetting solve different problems. Grease and roots respond to jetting; a hard obstruction usually does not.
Older lines treated carefully
Aggressive clearing of a fragile clay or cast line can turn a blockage into a collapse. Condition gets assessed first.
Licensed for what comes next if it is the lateral
If the problem turns out to be the sewer lateral, we hold C-42 and can carry on rather than hand you to someone else.

Read MoreFrequently Asked Questions
Are chemical drain cleaners safe to use?
Chemical drain cleaners can effectively clear minor clogs but come with risks. They can be harsh on your plumbing, potentially causing damage to pipes over time, especially if used frequently. Additionally, they can be hazardous to handle and may release toxic fumes. Mechanical tools like plungers or drain snakes are safer alternatives. For persistent or severe clogs, it’s generally more effective to use professional drain cleaning services. These services use methods like snaking or hydro-jetting to clear blockages without the risks associated with chemicals.
How often should I have my drains cleaned?
The frequency of drain cleaning can vary depending on several factors such as the age of your plumbing, the volume of water and waste going through the pipes, and whether you have a history of clogs. As a general guideline, having your drains cleaned every 1 to 2 years is a good practice. However, if you notice slow drainage, frequent clogs, or unusual odors, you might need to schedule a cleaning sooner.
Is professional drain cleaning better than snaking it myself?
Yes, plumbers use video inspections and high-powered tools to fully remove buildup and spot underlying issues that DIY methods can miss.
