"Mike did an excellent job. He was very attentive to my concerns regarding the fill valve issue I've been having with one of the Toto toilets they installed. I am very satisfied with the resolution. Mike just reenforced my decions to use Valley for all my plumbing needs."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"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."

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"JPC came in and took their time to thoroughly inspect our kitchen so that they can give us options on how we can install a new gas line as we were switching from an electric to a gas range. Their pricing is very fair, they are friendly and courteous. When they found out that we forgot to purchase a flexible gas hose, they went above and beyond and went out to buy one. I will definitely use them again for any future plumbing jobs."

"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."

"I had 5 different plumbing contractors look at my needed repair. They all had basically the same solution and high costs. Harry looked at the problem (repairing and installing 80ft of copper plumbing from the main to my house) and came up with a completely new and better solution at a lower cost. Harry was diligent and responsive and truly cared about a quality outcome and a sound repair. I would highly recommend Harry for all your plumbing needs."

"When remodeling our house, pipe systems and solutions showed a high level of skill and craftsmanship. We were extremely happy with the results. Marvin was not only highly skilled but honest and showed real customer care which helped us prevent unnecessary spending, and he also helped us understand where we should invest when it came to materials and labor. I have personally recommended this company to a couple of friends because it’s not easy to find good and honest people."

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