"I stared to look for a plumber after I found water under my water heater. I jumped on Angi and posted my issue. With in minutes....Art messaged me and said he can be her 1st thing in the morning. BTW. This was 10pm at night. His quick response was a plus for me. I had one other respond but he over extended himself to my need. He came at 7amd and said....you need a new water heater. I can got get one and install it now. I was a bit reluctant and he said call me when your ready and left. My wife said his prices looked fair and he seemed like a good plumber. I called him back and said lets dance. He was back at my home in a hour and 1/2...and started the work. He protected my carpet and placed plastic on it. He warned my that maybe the cost might go up due to the age of the pipes and valves. He had the old one out and the new one in an an hour or so. He was quick, clean and polite. I paid him and shuck his hand. I recommend Art for your household plumbing needs. He was excellent."

"Juan and his team came through once again with superior plumbing work and service. They had helped us prior with some hammering issues that they were able to resolve. A few weeks later, unrelated to the prior work, we had a clogged main line. Juan and his team came out the same day and assessed the issue, hydrojetted to clear out the main line of some roots, and problem solved once again! Every plumbing company should model themselves after this company. The quick responses, customer service, fair pricing, and great work makes Juan and this company my top recommendation when needing plumbing work."

"Art was extremely helpful and accommodating at every step of the project, from bidding through scheduling and even some additional work we needed a few weeks later. The team worked efficiently, doing a new main line install (going under our sidewalk and concrete without any demolition), re-piped the horizontal pipes under the house with copper (they were 100 year old galvanized), and setup a new shut off and regulator outside. They did everything in a day and cleaned up nicely. When we had other contractors working on our foundation 2 weeks later, they bent over backwards to get plumbers out the next day to make some fixes to drain pipe and at an excellent price. I got quotes from three companies and Repipe Pro was the most competitive and also great responsiveness from Art and his wife Thelma who run the business. To anyone looking for a repipe of a home or new main line or having drain work done, I definitely recommend contacting Art at Repipe Pro."

"I recently had the pleasure of working with Pearl Remodeling on a full kitchen and bathroom remodel, and I couldn’t be happier with the results. From start to finish, the experience was seamless, professional, and actually enjoyable—thanks in large part to my contractor, Ben, who was an absolute standout throughout the entire process. Ben was communicative, detail-oriented, and incredibly respectful of my time and home. He kept me updated every step of the way and made sure all my questions and concerns were addressed promptly and thoroughly. His crew was equally professional, showing up on time every day, working efficiently, and keeping the space as clean as possible (special thanks to Daniel for coming up with the backsplash border tile idea!). The quality of the workmanship is top-notch. The kitchen looks great and is highly functional, and the new bathroom has transformed the way I use the space. Every finish and fixture was installed with care, and it’s clear that Pearl Remodeling takes great pride in their work. What impressed me most was Ben’s commitment to making sure everything was done right—not just quickly. He noticed things I never would’ve caught, and applied his own high standards to my project. I’m incredibly grateful for it. I wholeheartedly recommend Pearl Remodeling—and especially Ben—to anyone looking for high-quality, reliable remodeling work. If I ever take on another project, they will be my first call!"

"These plumbers were awesome. They were prompt, professional, pricing was reasonable, and they were very respectful while in our home. They wore booties, used drop cloths, and our home was left in a good condition when they finished. Other large plumbing companies quoted outrageous fees for the same job which has resulted in me leaving them and providing additional business to ASO Plumbing."

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