"We used Kegonsa Remodeling for a major kitchen renovation in a nearly 100-year-old house. Before the remodel everything in the kitchen looked cheap and worn down (think 1970s brown, everywhere!), and the overall arrangement of the space was really inefficient. They came in and proposed a design that was the best balance of affordability and ideal features out of half a dozen contractors we interviewed. Once we began working with them, they provided consistent updates and met with us on a regular basis, enough so that even with unavoidable pandemic slowdowns, it still felt like the project was always moving forward. Once the remodel began, they had nearly daily updates for us on what was coming next, and the project actually finished ahead of schedule! Now we have a kitchen that has at least 3x the workspace, a significantly improved flow, and easily twice as much storage as our previous one did. We get compliments all the time, and recommend Kegonsa's work any chance we get!"

Kegonsa Plumbing was founded in March 2018 by Luke Elsing. After 13 years of plumbing experience, he was exposed to several different owners and management styles. Luke decided to be a different kind of business and prioritize doing what’s best for his customers over his own profit margins. By sourcing only the highest quality products with solid warranties and doing craftsman-quality work on every job, Kegonsa Plumbing earned an A rating on Angie’s List in our very first year of business.

FAQs for plumbing installation for a remodel or addition projects in Cottage Grove, WI

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.
