"We had some major under the foundation concrete slab corrosion of piping in our home. EZ flow did a thorough inspection and found the issues. We had some heavy work to do in order to fix: remove shower, tub, punch a hole in the concrete, and dig a hole under the house to expose the plumbing. The EZ Flow Team of Robert, Spencer P and Manny did FANTASTIC WORK! They also left the home in good / clean condition after a 12hr day of hard labor. We appreciate their efforts and attention to detail. Thank you EZ Flow!!"

"Karl & his son Samuel were absolutely amazing. They arrived on-time for the consultation & gave an estimate on the spot. We decided by the way they communicated & presented themselves, that they were right for our plumbing job. They replaced all the valves and water lines for 4 bathrooms & kitchen. They had to troubleshoot a leak in the downstairs bathroom, repaired & installed an access panel for any future issues. I cannot say enough how trustworthy & professional Karl & Samuel were. We definitely will be using them in the future!"

"Everyone I spoke with was responsive and professional. My water heater had split down the back during the night so my main water valve was turned off. They sent someone out in just a few hours and followed up with me from the office to ensure I was receiving timely service (considered an emergency I believe and they worked me into their schedule). I have forgotten names, but the service provided by them, from the owner, installer and office manager, was excellent. Additionally, the installer of my new water heater managed to get the job done in the same day, was cordial and professional in all respects, and did not display the condescension that is sometimes adopted when a workman is dealing with a single woman (those workmen/companies never get my money btw). I am very satisfied, appreciative of the quality and speed with which they resolved my problem, and would highly recommend them to anyone. Later, when I researched the cost of what I purchased, their charge was within the normal range for a replacement water heater installation."

"I found Ironwood Valley Plumbing on Angi's list and had a great experience from start to finish. Scott responded within minutes of my inquiry and even made time the same day to come out and assess the scope of the work, which I really appreciated. On the day of the job, he arrived right on time and communicated clearly throughout the entire process, explaining what he was doing and making sure everything was done properly. He also went the extra mile to ensure the installation was clean and efficient. Overall, the service was professional, responsive, and high quality. I will definitely be using him again and would confidently recommend him to friends and family."

"We are so happy with our bathroom remodel. Kyler is amazing. He had to jackhammer our floor to relocate the toilet. He refilled and leveled the concrete floor and installed new piping in the wall. Kyler is an absolute professional. He pays attention to detail and he follows Covid protocol. Kyler is very respectful of property and cleaned up the jobsite meticulously each day. He is a great asset to Tucker Hill. We highly recommend them for all your plumbing needs."

FAQs for plumbing installation for a remodel or addition projects in Scottsdale, AZ

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.
