"The technician was very nice but he arrived 2 & 1/2 hours after the confirmed time window. He did not have all the necessary parts to complete the job and had to make a run to get them when the job was half way finished which added to the already big delay. My biggest disappointment was the price. I purchased the special from Angie's list which was $799 installed. They informed me that if I needed any coils and other supplies, they would have them on the truck and available to purchase. The clincher was, they didn't tell me that they would not warranty the heater or installation unless I purchased the additional parts from them. This amounted to an additional $550. So, the deal I thought I was getting was voided by the additional cost of parts."

"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.."

"Woke up to my wife saying , "Oh no the water heater is leaking water all over the laundry room!" Quickly turned off the water, drained the tank and called Mark from Private I Plumbing. He immediately reassured me he could handle the job and get our hot water running THAT DAY. Which is exactly how it went. He was personable, proficient, and very pleasant to deal with. One hundred percent professional got the job done smoothly with excellent communication and attention to detail. It's really a pleasure to find a guy to know he will do a great job for a fair price. I recommend him without reservation."

"Iron Earth is the complete deal. They took down an 70 yr old garage that had seen much better days and replaced it with an exciting new garage and RV Port with a storage loft. Dan Faris and his crew did a marvelous job of tackling every step of the process; from planning, permitting, design, teardown, removal of old garage and every facet of the build. Unlike some contractors I've experienced in the past, he listened to our wants and needs. Discussing what could and couldn't be done while providing the details. I knew they were offering us to be partners in the process, not telling us what the project would be like others had. The team was professional and reliable i knew I could trust them in every facet. Iron Earth Construction and Dan Faris will be my go to for future projects, as I know I can rely on them."

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