"We had a great experience with Knockout. Small plumbing repair job that they were able to fix quickly. Gave us multiple options on how best to address the immediate problem, as well as prospective problems in the future. No complaints and would definitely hire again."

"I have hired this company on many different occasions by this point. Hot water tank replacement both electric and gas, re-plumbing a house, finish trim such as vanity, bathrooms, kitchen sink, etc. Installing clean out for mainline side sewer, scoping and clearing obstructions for mainline side sewer, digging down and replacing clogged side sewers. What is impressive and important to me is the sense of urgency, attention to detail and quality of work. In my 20 years of looking after houses, Nathan is by far the best plumber I?ve ever worked. And on top of all of that, I find the pricing to be very competitive.."

"The professionals who came made a thorough assessment of what needed to be done. The job was split between the plumbing techs according to their expertise, and each part got completed satisfactorily. I appreciated their honesty regarding what could be fixed immediately and the estimate for a bigger sewer-related job in future. The charges are reasonable. SEATOWN seems like a very organized company, their call center staff is friendly/polite, they follow through on scheduling appts."

"Diego first diagnosed our entire plumbing system as I asked. He was very detailed and thorough and carefully detailed everything, the good and bad. He gave me a bid and even suggested that I might get other bids. I developed a lot of confidence from the professional and clear manner he presented the needs we had for our plumbing update. My wife and I decided it was the better plan to just take care of all of it now ahead of future issues that we could face as the 50 year old plumbing system aged further. By the way, there was a crack in one part of the drain pipe and the water pipes were showing early signs of leaking at joints. Way over the top for me to want to just “keep my fingers crossed” on the future. Diego put us at the top of the repair priority list and completed all the work in 6 work days. Cudos to Debbie and Samara for coordinating all of the scheduling for the job and processing of the paperwork. They were absolutely super. A real special thanks to Diego, just totally top drawer to work with!! My highest recommendation to Apollo Plumbing!"

"Mark was able to replace my water heater quickly and efficiently and went the extra mile to make sure I understood the function of the heater and the water leak gauge -- my old one was improperly installed and submerged by water (super helpful. not.) On a follow-up call he even turned me on to a trusted electrician, cuz I need a bathroom ceiling fan installed. Two thumbs up!!"

Customers say: Super punctual

"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 Bellevue, 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.
