"Green Arrow Plumbing has been exceptional, and I’m very grateful that I trusted them with such a significant plumbing project. From start to finish, they demonstrated a high level of professionalism and attention to detail. What initially began as two slow-dripping faucets turned into a much larger job after they conducted a thorough inspection beneath my home. Their findings were later confirmed by two other companies, but I ultimately chose Green Arrow because they took the time to clearly explain their assessment and recommendations. In addition, their quote was considerably more reasonable than the others I received. Their team is knowledgeable, thoughtful, and highly skilled. The quality of their work was even confirmed by a contractor friend of mine, who described it as A+ craftsmanship. Green Arrow made the process far less stressful. I feel confident in the work they completed, the investment I made. Call them : )"

"Arrived on time, told me there were three possibilities for the source of the leak, gave me quotes for the different options, and said that he would start with the inexpensive option and if that didn't work we'd progress. The first thing he tried worked, and the price was fair. He reminded me, as he left, that the work was warrantied for 30 days and to call him if there was any subsequent recurrence. Very competent, friendly, professional."

"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!"

"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."

"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."

"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."

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