"Schmitty's Plumbing responded to my Angi's service request almost as soon as I submitted it, and they beat out three other Angi plumbing companies in terms of pricing and transparency. I hired Schmitty's to remove an old double bowl kitchen sink and faucet with a new single bowl sink and upgraded faucet. There was no upselling or attempts to convince us to replace our garbage disposal which two of the other plumbers recommended we do. We saw no reason to replace our disposal which functions well and is not that old. Partners Drake and Gage came out to our home as scheduled, and they got to work immediately working efficiently and thoroughly. We appreciated their no-nonsense, honest, prompt service, and very fair pricing. I chose Schmitty's based on the positive customer reviews, and would hire them again. I told them I would recommend them to all my friends who have plumbing needs!"

"HIired Serge Home Improvement, i for a partial remodel of the kids bath-new shower surround and flooring. During the time, I got the bid and he started work, the laundry room flooded and I asked if he could work on that too. Serge worked with the insurance adjustor and myself to bring the bid in at the insurance companies expectations. He had the laundry room up and running in a couple of days, with lovely new trim. This was a huge relief, as I had now washer for 2 weeks and laundry was piling up. Most of the bids I got for the bathroom work were in $15-$20K or more range. Serge's costs were reasonable and we agreed on what he'd provide and what I'd provide-tile and surround. When asked why the tub should be replaced he explained he wanted to make sure the plumbing was correct. He was right about that, the previous owner had "tiled" himself and done the plumbing. It was mess but Serge fixed it. Furthermore, he used lots of water proofing which gave me peace of mind as the kids splash like crazy. In 2 weeks, the bathroom was finished, and ready to use. I had him re-caulk my tub, and replace light fixtures in the dinning room and family room. It cost a small bit more than I budgeted, but having done remodels in the past I expected that. We are thrilled with the updated bathroom and new light fixtures. I a already discussing future projects with Serge. The best thing about Serge is his doesn't do mind doing projects on your house off and on. My previous contractor stopped taking my projects, because "projects to small and piece meal". Thankfully, Serge doesn't have that attitude."

Customers say: Super punctual

"These guys were amazing! We had the plastic water intake valve behind the toilet burst and spray water everywhere at 4am. after cleaning up the mess we called Cahill's at about 6:45am and they arrived by 8:30am to fix the valve, which took them like 15 minutes. I asked them about doing all of the valves in the house (16 total) and they agreed to come back at noon to do all of them. At exactly noon they were back at my house and had all the valves changed out in less than 2 hours. They were friendly, clean, polite, and provided excellent customer service. Jason and Harry were the team that came to my house and I would highly recommend them. And thanks to Russell, the owner, for giving us a great deal on the work his team did. We will be calling on Cahill's for any future plumbing needs."

"I cannot recommend Greener Cleaner Heating & Air enough! We've used them for our heating/cooling projects for over 5 years. We needed to replace our water heater and they were my first call. As usual, the technicians were professional, friendly, and communicative from start to finish. They kept the workspace clean throughout the job and left everything spotless when they were done. Top quality work and excellent service every single time. This company is made up of great people who go above and beyond for their customers. I'm so thrilled with my new water heater! Greener Cleaner will continue to be my go-to for any future work. - LKA"

"One could not ask for much more with Vlad from AWP. He was willing to take the time to discuss what he was doing and explain options. His work is very neat and precise and he maintained a very clean work environment. As someone who does most of their own work, I can assure you that I will utilize AWP for all my plumbing needs in the future."

"It took a few days for Danika to get back to us, but that might have been due to going through an intermediate group to start with. Once they contacted us, they were responsive and took care of all our problems. It was a little expensive, but we havenâ t used a plumbing service recently, itâ s all expensive now. Very nice and helpful when they were here. Got to us quickly and gave us money saving suggestions and did quality work. I would recommend them for any plumbing needs!"

"Very happy with the entire experience. Got an estimate which was the lowest of the 4 plumbing companies that I contacted for the job. I felt the price was reasonable and pretty close to the price I thought it would cost. The job was done at the agreed upon estimate quote price, no additional cost after the fact. I was able to schedule the job next day. The Plumber was on time and only took him 1 1/2 hours to complete the job. Work was very well done and very happy with result. Cost - $1,339.00 + Tax."

FAQs for plumbing installation for a remodel or addition projects in Black Diamond, WA

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.
