"Wes @ Rapid Rescue Rooter & Plumbing did an amazing job fixing our plumbing issues and even gave us advice on how to properly care for our drains and system to avoid problems in the future. Very, much appreciated!! Wes was quick to return our call and schedule an appointment that worked best for us. I also scheduled for work to be done at my parent’s home, knowing they would be in knowledgeable, trustworthy hands! He is definitely highly recommended! Thanks so much Wes!"

"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"After getting different quotations from different construction companies, even Home depot, AGL gives us reasonable pricing options. They did such a good job on remodeling two of my bathrooms we had a special request canceling a door and opening another, and the outcome was amazing. We went from having one bathroom and a half to two full bathrooms. After seeing the amazing job that they did with the bathroom we decided to also remodeling our kitchen with them it was the best decision."

"Makeitdrain.net (844)-697-7170 Ean at Make-it-Drain Plumbing has done exceptional work for us. His knowledge and expertise is invaluable. Six years ago when I received a water bill for $1500, he replaced a leaking water main line from the meter to the front of of our house. The original copper line was too thin and ruptured after 5 years. Several years later, our ‘special needs’ son developed the bad habit of flushing baby wipes down the toilet. After cleaning out the line several times, Ean recommended we upgrade the sewer lines. The old(1958) galvanized pipes and clay sewer line had rough edges inside that catch the wipes and clog the lines. We replaced 110 feet of clay pipe and a couple hundred more feet of galvanized pipes with P.V.C. lines and haven’t had any issues since. He also upgraded our water heater when it failed. He’s our first call for all maintenance issues at our house. His network of contractors is excellent. We are eternally greatful to Ean for all his hard work. We estimate he has saved us more than $10K over the years. It’s good to know we have a seasoned veteran who can handle any issue. We recommend him to all our friends and family."

"While I was painting behind my stove I bent down next to the gas line and actually felt air blowing from a hole in the line onto my cheek--but the air was natural gas. I knew I had smelled some gas, but I kept assuming it was the pilot light. Nope, it was a huge leak in the gas line. No wonder I felt light-headed. I called So Cal Gas to come check it out and their tech replaced the line, but when he tested the pressure on the gas line in the whole house there was still a significant leak. Yikes. The gas company shut off the gas to the entire house, so no cooking, no hot water for showers or laundry. I called another different plumbing company who charged $99 to do an initial visit--wherein they wanted me to sign paperwork for a $600 test of the gas line--but on the first visit they didn't do any work, so I would need to schedule another appointment for a few days later for the gas line test. More cold showers for me. I was informed that if they would cap all of the appliances, then if the line was still leaking, all the horizontal lines would need to be replaced which would be about $9,000, then if that didn't work, all the vertical lines would be replaced for about another $2,000. So upwards of $11k. I asked around and everyone told me they thought that was too high, so I started looking and I found good reviews on Angi for Andy Castillo Plumbing. Their technician, Gus, came out the next day, and immediately went to work. Their gas line test was about $300--so HALF what the other company was charging, and there was no $99 initial visit fee. Gus replaced all five of the interior gas lines and old valves to see if that would hold pressure (and to bring the lines up to code, which they definitely were not). IT WORKED!! Instead of spending $11,000, the entire job cost about $900. Gus checked the line for pressure multiple times to make sure it was holding, then he did it again in front of me, so I could see that it had been repaired. When the gas company inspectors came, they said the line was solid, and they restored my gas!! The entire time Gus was there, he explained everything he was doing and why he was doing it, in clear terms. When I asked him how much it might be if he needed to replace all the gas lines (if the pressure didn't hold), he told me it would be around $3,000--which is almost A QUARTER of what the other company would have charged for the same service. My old plumber retired and I've been looking for someone reliable, honest and skilled to do periodic work on my 110 year old house--and now I found him. Gus is amazing, this company has honest, kind, clear, skilled plumbers, and they are now my new plumbers! (and there have been about four other companies I tried before them for other plumbing jobs, so I don't say that lightly.)"

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