"Leo and Tony and Able are wonderful and amazing. They installed new shut off valves throughout the house and the main. New P-traps throughout, power washed all my decks and fixed two leaks on the second floor and repaired the ceiling. The most beautiful work was installing a new bathtub and tile surround. Able is an artist! Leo is so fair and honest and his team just works hard every minute they were at my house. Came when they said they would. Gave me updates. Did additional work that I asked them for. I would hire them again in a heartbeat."

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"I had a great experience with them. They did a tankless water heater for a fair price and helped install new water lines for my espresso machine in my cafe. Would recommend to anyone who needs the job done right!"

"Leo and his crew are skilled craftsmen. They do a variety of work and do it all right. They refused to settle for anything less than perfect and gave the extra effort to make the project gorgeous. They really cared about their work and showed excitement about the final product. They should be excited. It is beautiful! They patched a ton of drywall that we had removed as result of a skunk dying in the walls. They worked with our situation (pretty stinky at first) and took great care in replacing the drywall and insulation, matching texture (best I have ever seen), and painted three separate colors with perfect lines. They even came back and touched up areas that THEY were not satisfied with and then left the place spotless. Their work upgraded my space significantly. I look forward to our next project with them."

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