"I called just minutes before 10pm and expected to be told I'd have to wait until morning for a plumbing issue. Instead Jake showed up happy, polite and willing to find and solve our issue with in 35 to 40 min. Let me tell you Jake worked on our house for 2 hours solid, determined to fix our problem. Jerry showed up after Jake had been diligently trying everything to offer an extra hand. Both Jerry and Jake then worked an additional hour before finding and fixing our issue. Let me tell you, it was now very close to 2am!!!!!! This customer service, dedication and hard work was appreciated so much! I cannot say enough good things about Jake, Jerry or this company. Very honest, hard working people. Its hard to find this type of buisness nowdays!!!!! If i ever have another issue I will only call and use Liberty Plumbing and Heating. I sincerely Thank you for everything!!!!!"

"I have my regular plumber but wanted a second quote so I went on the Angie app. They recommended several plumbers to install an automatic water main valve shut off unit that I needed for my homeowners. AXP contacted me on a Sunday and had a technician out by 9:00 on Monday. Felipe was wonderful and gave me an extremely reasonable quote. His boss, Albert came with parts and they did the work. Came across some excessive root problems but fixed the issue that made the job harder and longer but they got the job done!! Very professional and kept me abreast every step of the way. I would highly recommend this company!"

"Anthony Fankhauser (Owner) is an exceedingly polite individual who provided detailed information on work to be accomplished. Unfortunately, the day my septic tank was being pumped coincided with a number of issues Anthony was experiencing on another job. For that reason, my task was delayed until after 6:00 PM. When Anthony arrived late in the evening to complete the work, he performed camera inspections and explained some minor issues. There was no indication of irritation or frustration due to the issues related to his other task. This was refreshing since I sincerely expected him to vent regarding problems experienced with his other work. I seriously recommend using Anthonyâ s services if you have plumbing issues."

FAQs for plumbing installation for a remodel or addition projects in Corona, CA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
