"We will be using Schmitty's Plumbing for all of our plumbing work from now on! We were able to get an appointment quickly, and Brian was on-time, pleasant, and professional. He was clear upfront about costs and options, explained the work that was needed, and quickly made the needed repairs at a reasonable cost. We are very happy to have found a plumber that we have confidence in."

"Drain Pro plumbing installed a new Toto flush mount toilet for us which requires a bit more work and effort than standard toilet installations. The technician was extremely knowledgeable, professional, and friendly. They have done other projects for us in the past such as convert a single vanity in the master to a dual vanity and redo plumbing in the kitchen to accommodate our IKEA drawer. I would hire them again for any future projects."

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."

"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."

"They provided me with information about repair of three 23 year old builder grade toilets vs replacing them. Gave me price options for toilets that would meet our needs, arranged for removal and installation within a couple days. They were here on time and within 1 1/2 hours had removed all 3, cleaned where the old toilets had been, hauled them away and had installed and caulked all 3 and were in their way. Their plumbers were respectful, friendly and professional and did a great job. I would recommend them to anyone and will definitely use them for future 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."

"The installer for my new dishwasher was refusing to finish the installation until the repairs were done and I needed repairs done as soon as possible. I called Vortex, they came out the same day, got everything fixed (and improved!) and were done very quickly. They were courteous, professional and explained what they were doing every step of the way. highly recommend them and I will use them for any future plumbing needs."

"Rick's crew did a marvelous job.  After having four other companies come out and give us bids on fixing our "lagoon" in the backyard, Four Aces came up with the most logical, simplest solution for the best price.  Their solution was to install four actual drains in the yard and connect them with the drainage pipe leading to the storm sewer. It was a no brainer.  They were easy to schedule and they completed the work in half the time we expected it to take.  They were even considerate enough to work the loud stuff around my baby's nap schedule.  They had warned us that they were probably not going to be able to completely restore the lawn and landscaping, but after they were done...it looked better than before.  (I'm pretty sure someone weeded a little.)  This was still a big household project for a family on a budget, but we were so excited to see that the water did in fact drain down after the first big rainstorm.  Now every time it rains, I truly enjoy going into the backyard and seeing that the "lagoon" is gone.  They completely solved our issue."

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.
