"Jess was did a fantastic job installing a sewer clean out for us. We had a major backup, sewage had backed up into the tubs and he came out on a Sunday to address our emergency. He was very communicative and explained the whole process. I will definitely hire him for all our future plumbing needs!"

"We needed our Garbage Disposal replaced. We bought one, but realized we needed help to get it installed. Mike Counsil to the rescue. This is the 3rd time we have had work done by them. Last year they redid the pipes in our house, so it was a no brainer to call them for help with disposal installation! They communicate during the entire thing. Called and showed up when they said they would. This time we had Besmir and Jordy doing the work. Very friendly, explained what they needed to do, made suggestions along the way. Cleaned up afterwards. Great experience overall!"

"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."

"Great service and quick. Plumber was very knowledgeable. Only negative was the appointment schedule. I was told between 1pm and 2pm but the plumber didn t arrive until 4pm. I think the dispatcher or owner needs to work on how to schedule clients. Plumber for me has no fault in that."

"Sergio and his team came to our rescue after we had our water heater shut off by PG&E for a safety issue. We received a detailed estimate after a thorough evaluation. Sergio provided us a range of options and patiently answered all our questions. We decided to also fix other issues we'd been considering and we were provided with a fair estimate for completing all the work at once. We agreed to also install a pressure regulating valve and a home filtration system. The Tankless Guys team was punctual on the day we began the work. They did the best they could to minimize disruptions, letting us know when we would have a water interruption and returning it as soon as possible. I was impressed by their professionalism, communication throughout the project, and attention to detail. They took their time to clean up the area they were working on at the end of the day, covering potential hazards and marking them off, and organizing the space to begin the next day. The team did uncover a couple of issues in our older home, which caused the project to take a little longer. They did not cut corners - Sergio, Daniel and Ray took their time to fix the issues so the installations could be installed properly and up to code, and to avoid other problems in the future. We are thrilled with the quality of the work, the attention to detail, and the peace of mind that our home is safe again. It was a pleasure to work with the Tankless Guys! I'm sure we will call them again for our next plumbing project."

"Bay Area Pro Plumbing did an outstanding job replacing our water main line. From start to finish, the team was professional, knowledgeable, and very efficient. They explained the entire process clearly, completed the work on time, and left everything clean when the job was done. The quality of workmanship was excellent, and we immediately noticed better water pressure throughout the property. It?s hard to find honest and reliable plumbers these days, but these guys truly exceeded expectations. Highly recommend Bay Area Pro Plumbing for any water main or plumbing work!"

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