"They responded to my inquiry quickly, arrived when they said they would, lived up to the quote they gave me, and did a professional job. Can't really ask for more from a contractor. Might not be the cheapest around, but you get what you pay for. I would hire them again if I need additional plumbing work done."

"We recently purchased a townhome and knew first thing 4 Seasons would be doing the work that was needed. I’ve owned several properties over the last 10 years and always do business with them (laundry/dish washer installs, bathroom remodels, etc) due to the quality of work, time frame of completion, and overall cost. This time we needed a full HVAC installation, they were able to send someone out for a consultation and within a few weeks we had the service completed. My wife and I couldn’t be more pleased. Would definitely recommend!"

"It went well. The team came and rodded the sewer as agreed. However the work I needed was not covered under the deal I purchased. They worked with me though and arranged it so that I only paid the difference in price between the deal and work they did so that I didnt have to vo theough the trouble of doing a refund first."

"We had an excellent experience with Windy City Rooter. Max (the owner) and his son came to my house to diagnose the problem and give a free estimate. Unlike with other "big name" companies, I felt comfortable with their diagnosis. Windy City Rooter sends actual licensed plumbers to your house and not uneducated salesmen guessing what the problem is and trying to sell you expensive sump pumps or experimental fixes. Although the diagnosis was not good (we had a blocked overhead sewer with a leak in our basement), Max was huge help in making the ordeal as painless as possible. He explained the entire process of replacing our sewer, including city construction codes, digging, replacing pipe, sealing walls, and clean up. Windy City Rooter does all their own work, they don't contract out anyone else (one of Max's sons is in charge of the excavating). Therefore they know everything that is going to get done, how much it will cost, and how long it will take. They dug up the sewer, replaced it, sealed our walls, and cleaned up all in one day as I was at work. Max was phone call or text away, keeping me updated on the entire process. In addition he also helped by talking directly to our insurance adjuster to ensure we could get some money for the damages. Windy City Rooter is a highly experienced family run business and it is obvious that their goal is to make the customer happy. I will use them for all my future plumbing needs."

"Markus performed the work on the dates agreed to, on budget and took the time when it was time for payment to show me videos and photos of how he completed the work to ensure I was comfortable with the job performed. I was impressed with his thoroughness and professionalism and would recommend Progressive Restoration for projects both large and small."

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