Frequently Asked Questions
How do I know if my commercial property needs a plumber?
Common signs include slow or backed up drains, low water pressure, water stains on walls or ceilings, unusually high water bills, foul odors coming from drains, or any visible leaks. If you notice any of these issues don’t wait — small plumbing problems in commercial properties escalate quickly and become significantly more expensive the longer they go unaddressed.
How often should a commercial property have its plumbing inspected?
We recommend a professional plumbing inspection at least once a year for most commercial properties. High volume businesses like restaurants, hotels, and senior living facilities benefit from inspections every 6 months. Regular inspections catch small issues before they become costly emergencies and help keep your property up to code.
What is the difference between residential and commercial plumbing?
Commercial plumbing systems are significantly more complex than residential systems — larger pipes, higher water demand, more fixtures, and stricter code requirements. Commercial properties also face heavier daily use which means more wear and tear on the entire system. Hiring a plumber with specific commercial experience is critical to getting the job done correctly and up to California code.
Do you offer emergency commercial plumbing services?
Yes — we are available 24 hours a day 7 days a week for commercial plumbing emergencies throughout North County San Diego. Whether it’s a burst pipe, sewer backup, water heater failure, or active flooding we respond fast to minimize damage and get your business back up and running as quickly as possible. Please call us at 760-626-4204 if you have an emergency.
How long does a typical commercial plumbing job take?
It depends on the scope of the work. Simple repairs like drain cleaning or fixture replacement can be completed in a few hours. Larger jobs like water heater replacement, pipe repair, or new construction plumbing can take anywhere from one day to several days. We always provide a clear timeline upfront before any work begins so you can plan accordingly.
Are you licensed and insured for commercial plumbing work in California?
Yes — Alonso Plumbing Inc. is fully licensed, insured, and bonded in California. Our CA Contractor License number is #1145697 which you can verify directly on the CSLB website. We carry full liability insurance on every commercial job to protect your property and your business.
How do you minimize disruption to my business during plumbing work?
We understand that downtime costs your business money. We work efficiently, communicate clearly about what to expect, and whenever possible schedule work during off hours or overnight to minimize impact on your daily operations. Country clubs, hotels, and high end commercial clients especially appreciate our flexible scheduling and professional job site standards.

Yes — we provide free upfront estimates for all commercial plumbing projects.
