"Ned with Mast Plumbing has been great to work with. I?ve hired him for work at my house, which involved relocating the plumbing for my washing machine, extending and repairing some water and drain lines. Ned has also helped several of my friends and some of my clients I?ve referred to him with projects ranging from plumbing new gas lines, tankless water heater installs and installing new water mains. Ned is clearly very experienced, professional and patient. He explains the process clearly, and is honest about your best options. I highly recommend Ned with Mast Plumbing, and will continue to refer him to anyone I find in need of a quality plumber."

"They were able to give me quote over the phone and also schedule me the next day! Harry called me in the allotted time frame and stated he was 10 minutes out. That gave me enough time to lock up the cats. He arrived and put on booties which was very nice, and got straight to work removing the old faucet and then installing the new one. He finished installing and cleaned up everything and explained the final bill. Was a great experience!"

"Garret was referred to me by my brother in law who is a plumber. Garret worked on. Two of my rentals. Repairing a leak and replacing a kitchen faucet at one house and and at the second he replaced a hot water tank. The hot water tank had been leaking for awhile and Garret recommended that the floor be replaced(it was pressed partial board that had been softened by the leaking tank). He brought everything “up to code” so I know going forward that this. Project is completed. The work was done quickly and I paid a fair price for the work. I will be calling Garret in the near future to replace a few more Hot water tanks BEFORE. They damage the floor!"

"Fantastic. The majority of work was done in 3 days. Unbelievable!!! The plumbing under the house was a really tight squeeze and it was done to perfection. He had to come back twice for the dishwasher because the door wouldn't close. It turned out to be a manufacturer's defect and had nothing to do with him. Great customer service.
When I bought the house, a plumbing nightmare was discovered. Mismatched pipes under the house  with a heat lamp (surprise!) Of course there was no indication of possible plumbing problems from the prior owner. If we hadn't inspected under the house, we would have had a nightmare in the winter. The shower plumbing sprayed water out the backside into a closet. The washer hook up did not have appropriate venting and the dryer vent went into the floor and under the house through nothing but a tinfoil dryer vent. The barn pipes leaked and one had burst during the period of time the house was empty.
I had 3 bids on this job. One was $10,000 with caveats about possible extra charges. One was $6500 with caveats about extra charges. JM Plumbing said both those bids were too high and he would be more than happy to do it for $6200.
Great job, great work, great customer service. I have recommended him to the Culligan Man as a top-notch example of what to expect from a plumber.

"Really enjoyed working with this company. They have top notch communication that automatically keeps you updated on the status of the appointment, when they will be arriving, and who to expect. A photo ID of Kyle was sent to me before he arrived, which was very helpful in knowing who to expect. Pricing was reasonable, and inline with other services. I like that they offer discounts to veterans. The faucet replacement was done quickly, and very professionally. The new faucet is solidly installed. No leaks or loose fittings. Very pleased! I will be choosing this company again for future plumbing jobs I have planned."

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