"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!"

"Zach and his crew were amazing! Our old water heater sprung a massive leak at 2:00am on a Saturday morning. Contacted Zach at 7:30am and he called right back and was here within the hour. Not only did we replace our water heater with a tankless model, but also moved it from the second floor to garage. Zach did all of this on a Saturday for a flat fee!! He and his crew were here for 9 hours without complaint or even seeming to take a rest!! Knockout Plumbing is indeed a 'Knockout' and I would highly recommend!! Kudos to all!!"

"Very well done! Tennant called to notify us of a leaking garbage disposal unit. Received a phone call when technician (Raman) arrived with a clear diagnosis before work was to be completed. Used an Angie's list special that was honored with no up-charges or additional work added. Drain Pro is now my go-to for all plumbing needs."

"Mad Pipers did an excellent job on the work! Zack provided the original estimate. He was responsive, punctual, answered all my questions and provided a very thorough estimate of the work we needed done in a timely manner. I took estimates from other companies but Mad Pipers was by far the the most responsive and for the large amount of work we needed done, they were also the best pricing. The job was completed by Zack and Ragen who showed up on time and were very professional. The work itself was a two day job. They made sure to explain everything that was completed. I was very happy with the work they did and as a result asked them back to provide an estimate for some additional (smaller scale) work I needed done on a guest bathroom (replacing old galvanized steel pipes with new copper pipes) and a master bathroom (replacing a popup & drain which was done by Curtis). I highly recommend Mad Pipers! I am so happy with the work they did and would not hesitate to call them again for any plumbing needs."

"Lead plumber Mitchell, did great service with even better follow up. As with a lot of services, it comes down to the actual person with which you interact. Mitchell handled a drywall repair issue related to the installation by taking personal responsibility and action to cover the cost himself. Seatown plumbing manager initially said they were not covering the repair, but after speaking with Mitchell this morning confirmed that Seatown will reimburse him for the cost of repair. Mitchell exhibited a high level of competency in his work, and an equally high level of character."

"Jason and Henry crawled  through a very unpleasant 3' space between our first and second floor to find out that there was a double ptrap install and the vent line just venting into open space. They corrected the plumbing, installed a studer cap and brought everything upto code (fixing the bad smell) problem.

I really appreciate there willingness to belly craw into a tight space to solve the problem without having to cut a hole in the celling.

They came in just under what they estimated it to cost. Showed up promptly and were professional. This is the second time I have used Cahill's Plumbing and have always had a good experience.

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