"Great! They were unable to get all the way to the street from the catch basin. It was suggested I add a sewer clean out assure all the roots were gone and make it easier for future cleaning. This was suggested in the past, by another company , but the cost was out of sight. This company was very fair in price for both the cleaning (which included the inspection with the camera) and for the clean out installation."

"Outstanding! Tony was able to come to the condo within the hour. He had the missing part and explained what he needed to do and the charges before the work was started. He replaced the valve in quick order (allowing the water to be turned on in the condo) and when he was done, he further clarified what needed to be done to replace the trim kit and provided some options to reduce the overall cost by finding us replacement parts on line. In the end, he saved us an additional $160 by sending us to Home Depot for the new part."

"Really well. I got an estimate up front but couldn't get the work done until after a 48 delay. A notice needed to be posted in my building regarding the water being shut off in our building. Anyway the actual plumbing was scheduled and then completed within a timely manner. I was more than satisfied with both the plumber & the work that was done."

FAQs for plumbing installation for a remodel or addition projects in Union, IL

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.
