We have been serving the Greater Puget Sound area since 1982. Today we serve all of King, Pierce, and Snohomish counties. South West focuses on customer service as the differentiating factor between our company and other plumbing, heating, air, and electric contractors in the area. Our expertise, support staff, and quality work will earn your business for years to come.

"We Had Southwest Plumbing come to our house to attatch a hose bib that my husband wasn’t able to do because of the angle of the piping. He had the crawl space totally accessible and plenty of room to it as well as cob webs etc cleaned out of there. Hose bib was already removed from house. We also had a new hose bib on hand. It took the plumber 7 min to do the job. They quoted 1048.00 and we assumed they would deduct a couple hundred off when the job was done, it could not have been easier for the plumber. Again 7 min job…….. I have reached out to them 3 times to talk to Andrew which I’m sure is a manager. He has NOT returned our call. A call back and parcial refund would make all the difference as the plumber did his job well. With assessing the job they were at our house a total of 50 minutes and it cost over a 1000.00, very unacceptable. We are hoping they will make this right."

"It was way too expensive for the work that was performed. They originally said that the pipes leading up to the faucet may need to be replaced and the wall opened up. Previously before engaging them. I asked for a possible quote for how much it would cost and they told me that it was up to the technician. When they came out to do the work that they would determine the amount. I asked the technician how much it would and he told me that it was up to the company to decide for how much the work would cost. When I contacted the company they told me again that it would be up to the technician to determine the how much it would cost by checking the amount of work. I could not get an answer from both of them because they would just keep passing each other on who to ask for the quote. After the project was completed, I was given the bill of about $750+ to replace the faucet, to replace the hoses and the two knobs roughly $350+ each. When I called the company about the price, I was transferred to the dispatchers and was told that I need to talk to the technician for it."

"I found the leak in the attic and knew exactly where to find it. I had to let them go through my room ceiling after looking at where the burst was located. No way they could get to it any other way. Job done in an hour. Is $1k to expensive? When 1000's are experiencing the same issue? No you do what you need to do to come back online. I was happy with their business. They explained how to avoid this in the future."

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