"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"He installed a new toilet for us. I have health issues that require a taller bowl, 19 inches. Or more. He knew that we were senior citizens, so he found an economical yet classy toilet that met the requirements I asked for. He was quick with the installation and left the area cleaner than he found it. He was very friendly and courteous. I enjoyed talking with him, as I had worked for a plumber in my younger days and had done all the bathroom needs up until 5 years ago. A M Plumbing will be my go-to service from now on."

"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."

"This is the third time I have used Albert Nahman. This time was for a water leak with an unclear origin. They did a great job diagnosing the problem and took the time to explain what they found and offer options on potential fixes. I really appreciate the care their plumber took in tracking down the problem and providing a realistic quote for the cost and time to fix the problem. They also arrive on time and do a great job cleaning up after the work is done. A+++ company. Will definitely use them again the in future."

"Superior plumbing has saved the day for me on countless occasions. I hit a sewer pipe with a lawnmower because it was sticking out of the ground and hidden by overgrown grass. I didn't know what it was, and sewage started coming out a few days later. I had another plumbing company come out and quote me $30k for a sewer lateral. I then had Superior Plumbing come out since they had recently installed a sewer lateral for my parents' house for much less. They said a piece of the pipe fell into the pipe, causing it to clog. They pulled out the piece, then cut the pipe to the ground and put a concrete cap that said "sewer," so I wouldn't hit it with the lawn mower again. It cost $1700 instead of $30k! Last week, the landscapers hit the cast iron sewer pipe coming from the bathroom outside. I immediately called Superior Plumbing, and they came out in 30minutes, as luckily they were close by. They addressed the issue and returned a few days later to replace the pipe with PVS, which proved to be very affordable. I then had them return to strap pipes under the house and install a water pressure regulator, as the water pressure was 95 when it should be 60. This could cause major problems with too high water pressure down the road with burst or leaking pipes. Look no further than Superior Plumbing for your plumbing needs!"

"Now for the positive experience.  I called Clearwater Plumbing and left a message.  Larry returned my call within 2 hours.  Larry was very pleasant and answered all my questions.  I purchased all the material for replacing two toilets.  I just needed a quote for labor.   Clearwater Plumbing provided a very fair estimate.  I was also able to use Clearwater's coupon on Angie's List that saved me 10% on labor.  Larry scheduled to provide the service two days after I accepted their estimate.  Larry provided a two hour window for their arrival.  Tyler came to provide the work.  He called 15 mins before he arrived.  He wore shoe covers in my house which I really appreciated.  I have changed toilets before but since I had major back surgery my wife does not want me to get injured again.  I occasionally watched his work. Tyler did not waste any time installing the two toilets.  He completed the work on-time per the quote.  Tyler did a professional job and cleaned up the area when he was done.  I would definitely use Clearwater Plumbing again for any plumbing work.  I would also recommend them to all my friends."

After the technician assessed the problem, he used their snake to unclog the pipes. He also pointed out the root cause and gave an evaluation of our sink/drain conditions. He noticed a deterioration of the pipe seals and rings, so he replaced them to prevent leak problems. All of this within an hour at $110 dollars. As I was about to write the check, he reminded me that I get a discount for being a veteran so he charged me $96 dollars. How awesome!! I highly recommend Gladiator Plumbing.

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