"Install was on time and as described. '1st Response' did the job I expected for the water heater install. Good customer service for scheduling. Note that the Angie's list price of $799 only covers the installation of 50 gallon gas AO Smith hot water tank. Assuming you also do installation of new brass fittings, new flex lines and new expansion tank (which you should probably all do with the new water heater) it will cost an ADDITIONAL approx $500-600 (mostly labor costs). That's a competitive price but still, you should be aware that the original quote is just for the water tank install itself, nothing else. All-in-all they did a good job for a competitive price. A few months after the install, so far, I can say I would recommend them for this type of work."

"Drain Pro plumbing installed a new Toto flush mount toilet for us which requires a bit more work and effort than standard toilet installations. The technician was extremely knowledgeable, professional, and friendly. They have done other projects for us in the past such as convert a single vanity in the master to a dual vanity and redo plumbing in the kitchen to accommodate our IKEA drawer. I would hire them again for any future projects."

"They did an excellent job and everything was done on time and with exactness. They work very professionally but they also had fun as they worked. The final price ended up being right on with what the estimated price was. They provided all the materials and they cleaned up when they were finished and didn’t leave a mess behind for us to have to clean up. They listened to us and to what our desires were and then they explained the different options that we had. They were very respectful not only to us but to our property. They showed up on time when they said they would be here and the project was completed when they estimated it would be done. We would definitely recommend them for any plumbing job you have, we will call them for any future needs we have."

"I contacted Seatown Electric about installing a replacement bathroom fan; the existing fan (an inexpensive and loud NuTone) was undersized for the bathroom and leading to condensation. I e-mailed Lisa and Matt at the main office to get their input on a new fan with humidity-sensing capabilities, high airflow, and low sound.They sent me a suggestion for a high-quality Panasonic bathroom fan that fit my needs perfectly, plus an estimate that was very reasonable. On the scheduled day, Jeff and his assistant arrived and got right to work: they spread out some protective gear for my floors, removed the old ceiling fan, enlarged the ceiling cutout to accommodate the new fan, and had the new fan installed in just over an hour. I was particularly impressed at how carefully Jeff removed the old fan - it wasn't as easy as simply pulling the old one out, but he took the time to cleanly remove it from the ceiling without unnecessary cutting or leaving behind any stray mounting hardware. To top it all off, Jeff and his assistant cleaned up all the stray dust and insulation that had fallen from the ceiling. In the end, I had an awesome new ceiling fan with a humidity sensor that was installed in much less time than it ever would have taken me. :-) I'm very happy with Seatown and will be hiring them again."

"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."

"ONeill Plumbing hit another home run with James and Kyle. They were prompt, courteous and knowledgeable. James imparted quite a bit of wisdom when it came to contacting my faucet manufacturer for a replacement part and Kyle told me how to deal with the water company should I ever experience a broken pipe and any resulting water bill issue. O’Neill Plumbing has been my go to plumber for many years and James and Kyle have definitely made sure I won’t be changing anytime in the foreseeable future."

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.
