"Ned from Mast Plumbing did an outstanding job installing my gas tankless water heater. He was professional, knowledgeable, and took care of everything from start to finish. He made sure the installation was done properly, explained everything clearly, and left everything clean and looking great. The pricing was also much better compared to the larger plumbing companies, which was a huge plus. It?s great to support a local company that provides excellent work without the inflated prices. I really appreciate the quality of work, attention to detail, and customer service. I highly recommend Ned and Mast Plumbing to anyone looking for a reliable plumber!"

"They did good work. The only problem was that they kind of lost track of one of our checks. They called us about that a couple of times because they were sure they had not received a check, which they had, because they had deposited it. They did a really clean job and did not leave a mess. We were a small job so we were kind of fit in-between a couple of other jobs, I think. I used them because I think they had good ratings and comments on Angie's List."

"Paul is a peach. He’s patient and friendly and goes to great lengths to explain what is going on behind the walls and under the sidewalk. He takes what he does very seriously and keeps up with modern technology, which isn’t easy for smaller contractors. At all times it was obvious to me that he had our best in mind. He assessed our situation quickly and didn’t hold us up, getting permits or other paperwork , he got that all done without a hitch. Also The workers he hired to help him were all perfect gentlemen as well, And we enjoyed having them all here. Best plumber in the state!"

"Hagee Plumbing technician Caleb arrived on time, super friendly, and went straight to work. He was able to repair my garbage disposal and save me a couple hundred dollars in the process. I highly recommend Caleb and will definitely ask for him directly if I ever need any plumbing work done."

"Kairos is owned and run by women which we appreciated when we worked with them as two women.  They were punctual, and communicative, and also just great people that I was happy and comfortable with having in my home.  All of the staff are experts in many skills, and they have extended experts- i.e. a journeyman electrician- on staff to help/consult if they run in to anything hairy at your hours- ours is old, and of course this happened.  They also educated me so that in the future I could do a lot of these jobs myself, or even related jobs based on the same skills.  When we ran in to things, I never felt like they were short cutting, or anything that would compromise the quality of the work, and rather that they were going out of their way to make sure that the work was done in a way that they would want done in their own homes.  I'd definitely use them again, and I know it'd be a great job, with some great women.

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