"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend. "

"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."

"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."

"I use Counsil for the quality of their work and trust them to do it to highest city inspection standards. I had to do two replacement sewer lines. Counsil plumbing did the digging, plumbing and cement work with same people; the other contractor did plumbing, subcontracted sleeving sewer line and subcontracted concrete work. Counsil left the house as he found it. The other contractor left trash, rebar and wood and never came back. Counsil used a price master and a detailed contract, the other contractor gave me verbal price which became opaque. I use Counsil when i need quality work that meets inspection specifications and am willing to pay for it."

"Had a cracked undermount bathroom sink that needed replacement, which isn't really something either contractors or plumbers typically deal with. Luckily (and surprisingly) Mike Counsil Plumbing listed this service on their website, and they confirmed this over the phone. Called on a Mon. morning...very polite and helpful, scheduled earliest available appt. Wed. morning. Arrived within stated appt. window, and provided work estimate; separate pro came shortly thereafter to start actual work. Proved to be a difficult job to carefully remove old sink without damaging granite or wood countertops, but the pro did a great job. Although we furnished the replacement sink, the pro had to take a trip to the local hardware store to get additional undersink mounts - something we didn't anticipate. Once installed, it became clear that the new sink basin drain was closer to the back wall; so, to salvage the existing pipe, he took an additional trip to the hardware store to get an uncommon short pipe adapter, which he didn't stock on his van. Still ended up having to cut the pipe stub down to fit the drain and P-trap, but we appreciated the willingness to solve the problem - solve all of the problems that popped up, as everyones setup is slightly different. So, the pro ended taking several hours to get it all done, and the labor charge as you might imagine was costly...but fair. But the end result was a new, leak-free bathroom sink, as if nothing had ever happened. And, as a busy person who values their time, it was well worth it. I never noticed their green vans around town before, but I do now - Mike Counsil Plumbing services are clearly in demand, and it's obvious why."

"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.
