"Excellent service! We scheduled Plumbing Plus to replace the hot and cold cartridge's in a sink faucet and a tub pop-up drain and overflow gasket. Jared N. quickly assessed the problems. The faucet was so corroded with water deposits that it could not be dismantled to simply replace the hot and cold cartridge's. So Jared replaced the entire faucet with a high quality replacement. After the tub pop-up drain was replaced, Jared checked for leaks by looking in a 'trap door' in the ceiling below the tub that was left after the tub was replaced in an earlier remodel. Jared discovered that the entire tub drain was leaking and need to be replaced, which he did. He also corrected a problem with the drain pipe left from the previous remodel. Although the job was much more complex than expected, Jared was professional, efficient, and extremely cheerful throughout . We highly recommend Jared and Plumbing Plus"

"We had our tankless water heater drained - annual maintenance. They show up when they say they will and do it right the first time. In the past we've had issues with AC's, plumbing and more. Evey time they've exceeded our expectations and would highly recommend them for any heating, AC or plumbing. We've used them for well over 20 years and wouldn't want anyone else. They are the best."

"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

"I needed an old refrigerator water/ice line properly replaced. Ly’s Plumbing responded quickly and gave an honest assessment before starting the work, then triple checked the final result before patching and cleaning up. I’m very grateful the project turned out to be not too complicated, and also reassured for future projects."

"We used John Padilla Plumbing for a few separate repair and service calls since buying our new home. They repaired a pinhole leak in a section of our copper piping, serviced our tankless water heater, and replaced a leaking tub overflow. On every occasion their technicians were very thorough and helpful in diagnosing the problem and explaining the necessary repair/replacement steps. The work was completed in a timely and professional manner while at a reasonable cost. We will continue to use them for all of our plumbing needs and would not hesitate to recommend them to any of our friends or family."

"When we purchased the house, it was a 30 year old home. Almost everybody in the period of five years to seven years wanted to convert to copper plumbing. So what they offered at that time was anyone you referred to if they chose to use their service, you have $500 cash payment which was really nice because half of our neighbors and our family members used them. I do not know what they do now, but it is a really nice service because they are a very good company. They did a great job."

FAQs for plumbing installation for a remodel or addition projects in San Ysidro, 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.
