"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."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

"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."

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