"Mainline was the only business that replied although there were several listed from Home Advisor. They came the same day I asked about getting it done and completed removing the old water heater and installed the new one within hours! I could have waited to see if the parts I needed could be sourced but since the heater was 14 years old I opted to install a new one. Could not see possibly paying half the cost of a new one for service and parts and then maybe waiting for it to be completed only to have it need service or replacement a couple years down the road."

"Phil from PM Prestigious Plumbing was great! Very professional, responsive, and prompt. He understood the urgency of our issue (sewage was backing up into ALL bathroom tubs/shower pans) and was able to fit us into his schedule to resolve our issue. I would absolutely recommend Phil as a knowledgeable and valuable resource for your needs. Thanks again Phil!"

"The walls were down to the studs so the plumbers could access the pipes to convert them from a tub/shower set-up to a shower only set-up. This included installing a new valve for the shower. They did this part of the job on June 18. It took an afternoon and the job was complete when they left the premises that day. We paid them by check, $475. Once the shower pan, drain, and shower walls were installed the plumbers returned on August 14 to connect the drain and install the outside wall shower fixture and faucet. It took 3/4's of the day because they ran into an unforseen problem with our shut-off valve to the house. It failed to work properly and they ended up having to replace it. That was an additional cost which we agreed to pay ($300). The end of the day came, and the plumber took me into the shower stall to explain that the large rain-style showerhead is dripping, but those type of fixtures do that for a bit after the shower is turned off. We paid them $525 for the fixture and faucet install. Over the next 90 minutes I checked on the dripping fixture, and it had not stopped. It was more than a small drip. It was dripping a lot. I reached out to the plumber and he said the problem was likely the fixture needed replacing. The fixture was brand new out of the box. I did some research on YouTube about dripping shower fixtures and found that it is likely an issue with the valve. It could be damaged, faulty, or dirty. When I told the plumber this he disagreed. The next week he sent one of his guys back to look it it, and he said the same thing: The fixture needs replacing. You need to send it back and get a different type of unit. After this I went online again and found another opinion that it is the valve. So I sent the plumber a video of the unit dripping from the connection where I removed the hose shower head. When he saw this he agreed that it was the valve. However, he did not offer his service to come back to check the valve and provided a solution. This lead me to contact another plumber and this plumber concurred that it was a valve issue, the valve cartridge. He sent his guy over on August 25th, and he removed the cartridge and ordered a replacement one, and is going to come back on August 28th to install it for us. This is estimated to cost us $650, $400 labor and $200 for the cartridge. My gripe with the plumber I hired from Angie is that he left us with a drippy shower and did not care enough to come back and correct it. He made excuses that he was so busy and working out of the area. We did not pay a professional to leave us with a drippy shower unit. It is our opinion that the job was not completed satisfactorily. We kept having to turn our water to the house on and off because the dripping never stopped. The shower unit was turned off and it just kept dripping. The total we paid this company was $1300. $475 for the converted piping, $300 for the new house shut-off valve and $525 for the fixture installation. In addition, I asked the plumber multiple times to provide a receipt for the jobs they did, and have received no paperwork from them. This is most unprofessional. There should be a document with the charges and what they were for, and confirmation of payment."

"E Mays Plumbing was prompt to respond to my inquiries & came within 24 hours on both occasions I requested services. During the first visit, Mr. Mays showed me how to fix the problem with the water heater in order to save me money (rather than replacing the part or the entire water heater.) After a few weeks, I decided I wanted to replace the entire unit. Mr. Mays came to my home that same day & efficiently installed the new unit & hauled away the old one. He was very professional & even asked permission to pull into my garage in order to load the old water heater onto his truck. I will definitely call E Mays Plumbing for any future plumbing needs!"

"I’ve had various plumbing companies in the past and I think I’ve found one that I will continue to always use. It’s incredibly difficult to find a company to trust to not only solve your problem but entrust with a proper solution. My search ended with these guys, and I will be recommending to all my friends and family. Polite, affordable and trustworthy!"

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