"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!"

"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."

"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!!"

"We requested a bid for installation of recessed kitchen lighting. What we got was an estimate for the cost of rewiring the knob-and-tube in our entire house, plus the cost of the fixtures. The rewiring alone was estimated over $18,000. Our home inspector informed us about knob-and-tube when we moved in, as well as the excellent condition of the wiring. Adding LED fixtures would have been a low draw on the system and we have since gotten a far better bid from another electrician. Our impression was that we were given a hard sell to spend almost $20,000 on a big project we did not ask for. There was no alternative solution offered. Additionally, the price quoted for the fixtures was very higher, higher than any I could find on a basic Internet search for the same fixtures, so big price gouging there on the materials. I am confident that these are skilled electricians, but as a homeowner and consumer, I felt that we were not heard and that the company, as represented by the initial contact with the lead electrician who seems to primarily be a salesman, is interested only in big-ticket jobs. If you need a big commercial project done, you may find Seatown to be your best choice. As a homeowner, I felt like the company's next prospective sale. We won't hire this company."

"I needed some additional work done to remove a kitchen disposal and put new pipes in and also to have pipes replaced on a back bathroom we had just remodeled. Mad Pipers did such a great job with the large re-piping job I hired them for over the summer, I didn't hesitate to call Zack & Ragen for the quote for the additional work. They replied promptly and we scheduled the work within a few days. The work was completed by Curtis who arrived on-time and did a great job! I wouldn't hesitate to recommend them to anyone in need of plumbing services!"

"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."

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.
