"Gustavo and his crew did an excellent job converting my gas fireplace to an electric fireplace and replacing the old tiles; this was all completed within three days at a competitive price. They were professional, highly skilled, easy to work, and checked in with me during the process. Ex: during the demolition, it was discovered that my old 30 year old fireplace was attached in such way, that more of the inside needs to removed than just the door and trim or frame. To install the new gas fireplace I’ve purchased would require additional piece(s); after a discussion we’ve decided it would be easy now to convert it to an electric fireplace if desired. As soon as the electric fireplace was delivered, Escamilla was back the very next day to continue. I am very pleased with my modern looking fireplace!"

"We needed a building cleanout installed as a requirement for our remodeling project. Cornelio was very thorough in investigating what were the requirements for the inspection. He installed a dual cleanout following all the requirements which will help us in case of any backups in the future. He was very transparent about the cost, and finished the installation on the following day. Highly recommend him for any plumbing issues."

"Jesus was awesome - not only was he the first to respond to my inquiry, he fit me in quickly after a weekend and did the best job of any plumber I have ever had service my condo. Not all plumbers do a thorough or ideal set up and Jesus corrected what was leaking and fixed prior issues. Personable, professional, and reasonably priced, I am definitely hiring him again for any future plumbing work!"

"The folks @ Mike Counsil have done work for us in the past, including the heater installation and unclogging/cleaning a backed up drain. Any time we've had work done by them, they are always right on time and very professional. They get the job done and clean up after they're finished to ensure there's no clean up for the customer. I highly recommend them for all of your plumbing needs."

"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."

"You will be so pleased that you chose The Tankless Guys to look after EVERYTHING and anything to do with plumbing in your home. Gert has been my go to professional for over 10 years for ALL my plumbing needs. He operates with the highest integrity. His top priority is to do what is in the best interests of his clients. Gert and Sergio installed my new water heater two years ago. Sergio stayed for much longer than he shouldâ ve after installation was complete. He took extra care to figure out how to program the timer for my existing hot water recirculator which was not part of the water heater job. He didnâ t have to stay, but thatâ s how Gert and Sergio are. True professionals willing to lend their expertise. Some plumbing companies out there send NOT very qualified plumbers to do the minimal and/or charge you a significant amount for unnecessary work. Gert is a straight shooter. He has saved me a ton of money to replace what needed to be replaced and NOT replacing what did not need to be replaced or fixed. He will tell you whatâ s the most economical and efficient and what you need to do to protect your home from future plumbing problems. If you want cut rate prices with NOT the most qualified plumbers, donâ t call The Tankless guys. If you are looking for a team who thoughtfully looks after your whole home and considers preventative measures that you might not have considered, Youâ ll be so happy you called the Tankless Guys. Remember you get what you pay for."

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