"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."

"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.

"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."

"One could not ask for much more with Vlad from AWP. He was willing to take the time to discuss what he was doing and explain options. His work is very neat and precise and he maintained a very clean work environment. As someone who does most of their own work, I can assure you that I will utilize AWP for all my plumbing needs in the future."

"Very happy with the entire experience. Got an estimate which was the lowest of the 4 plumbing companies that I contacted for the job. I felt the price was reasonable and pretty close to the price I thought it would cost. The job was done at the agreed upon estimate quote price, no additional cost after the fact. I was able to schedule the job next day. The Plumber was on time and only took him 1 1/2 hours to complete the job. Work was very well done and very happy with result. Cost - $1,339.00 + Tax."

"The installer for my new dishwasher was refusing to finish the installation until the repairs were done and I needed repairs done as soon as possible. I called Vortex, they came out the same day, got everything fixed (and improved!) and were done very quickly. They were courteous, professional and explained what they were doing every step of the way. highly recommend them and I will use them for any future plumbing needs."

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