Commercial Plumbing Repairs
When your business runs into a plumbing issue, it’s time to call in the professionals. Waiting to see if the situation will take care of itself is never a good plan when it comes to water problems. They typically grow bigger and more expensive quickly.
Our Ongaro & Sons commercial plumbing team will promptly assess the scenario and determine the appropriate plan of action. To avoid any surprises, we will discuss all choices with you before making your repair.
You can rest assured our team will never try to steer you to a new system if your current equipment is worth repairing. We want you to get the full life expectancy out of all your California company’s plumbing.
Commercial Plumbing Maintenance & Service
Like your company’s commercial HVAC system, as well as your commercial electrical equipment, commercial plumbing requires regular professional preventative inspections and maintenance to keep it operating at peak performance.
Setting up a consistent schedule for our commercial plumbers to inspect and maintain your plumbing is a sound investment in your business.
With routine assessments, we can alert you to any potential problems before they occur, saving you money in the long run. Having to shut down your California business due to a plumbing emergency is always worth avoiding.

Why Ongaro & Sons for Commercial Plumbing
In a commercial building the plumbing failure you can see is usually not the one that costs you.
Schedule Service →Licensed for the underground work, not just the fixtures
Ongaro & Sons holds C-36 plumbing plus C-42 sanitation system and C-34 pipeline. Santa Rosa requires a Class A or C-42 contractor for sewer lateral work and a Class A or C-34 for water service and meter work. We hold both.
Camera inspection before excavation is proposed
Locating the actual defect decides whether a line needs a spot repair, a liner or a replacement. Digging first is how a small problem becomes a car park.
Commercial water heating sized for real demand
Recovery rate, not tank size, is what decides whether a building runs out of hot water at eleven in the morning.
Backflow, grease and compliance work covered
Commercial premises carry requirements residential ones do not. We handle the testing and the documentation.
Scheduled so the building keeps operating
Family-owned in the North Bay since 1932, Diamond Certified since October 2016.
