"What do you do when the gas company turns off your gas due to a leak? You would want a licensed plumbing company that is: quick to respond, has a free estimate, comes out on a Saturday, knowledgeable, on-time, efficient, quality work, courteous, and above all else,...integrity. Jason and his team at J I G Plumbing are all that! We were given an initial estimate, but as the trenching started, he informed us that the repair would not be as extensive as previously thought. He re-calculated the cost, saving us considerable money. Jason and his team patiently answered all our questions and informed us of their progress. Jason also provided photos of damaged areas and the finished repair. The repair was completed professionally and efficiently, and the gas company came to inspect/turn the gas on the same day. We are happy to have J I G Plumbing as our "go-to" for all our plumbing needs in the future!"

"Guardian Plumbing repaired our high water pressure issue by replacing valve, flushed our tankless water heater, and fixed shower head leak. The repair cost was reasonable and the plumber was professional, courteous and did a good job with no issues. I will call them again for my next plumbing related service."

"HomeX technician Eddie replaced a broken water shut off valve in the bathroom & installed a replacement kitchen faucet. He was knowledgeable, friendly, efficient & responded to my emergency call within the hour. The HomeX office & dispatcher were very friendly & helpful. This is the second time HomeX has come to my rescue to take care of my plumbing problems. I will definitely call them next time I need a plumber."

FAQs for plumbing projects in Ontario, CA

Schedule a plumbing inspection every one to two years to ensure your system is in good working order. Regular inspections can help you catch minor issues before they become costly problems, like major water damage repairs. You should also consider a plumbing inspection when buying or selling a home or if you notice signs of a plumbing issue. Staying proactive with maintenance can save you money and stress in the long run.

A plumbing inspection for a standard one-story to two-story home takes between two and three hours. For larger residences, historic homes, or rental complexes, a complete inspection requires a full-day commitment of eight hours. However, this does not account for any necessary repairs that your plumber might find, so it’s best to set aside additional time during the inspection in case an unexpected repair comes up.

When built with quality materials, your plumbing system endures for decades. CPVC, brass, iron, and steel provide reliable service for 50 to 70 years, while copper extends durability up to 100 years, and PEX maintains performance for 80 to 100 years. Maintaining this system with regular inspections and prompt repairs guarantees long-term efficiency.

You should repipe your home when your plumbing exceeds its expected lifespan or uses hazardous materials like lead, polybutylene, or galvanized steel. Persistent leaks, corrosion, and compromised water quality signal that your existing piping no longer meets safety standards. Repiping eliminates potential health risks and prevents extensive water damage.
