"Garrett Korn was my installer from Mr. Rooter. I was informed prior to his arrival that he was on his way and he arrived shortly after 8:00 for an 8 - 10 AM window. He quickly analyzed our plumbing problem, gave us a quote right away (which I agreed to) and then left to get all the parts he needed. He was only gone for a short period of time, did all the work, and was totally completed before 10:00 AM. The quality of the work was very good and now we are up and running again. I would highly recommend Mr. Rooter and selfishly ask for Garrett. He is easy to work with and very competent."

"John has been our go-to guy for several years now. We live in an early 70s home, and as with all older homes there are repairs that are needed fairly often. From the first time he worked for us, identifying that a leak originated from a roof vent that had been knocked slightly askew in a storm and rain water had gradually seeped down the pipes and terminated above our kitchen cabinets, he has always been prompt, courteous, professional in every way, and just an all around nice guy to work with. And the pricing has always been fair. Since then he has installed a number of appliances and fixed sundry leaks for us. Can't recommend him or his company enough. Give them a try."

"Smooth as could be from call to completion.  For $279 (Angie's List deal) they came in and reglazed our nasty old tub to a sparkling white new finish.  It was fast, too. Our old tub had been flaking and chipping - it looks BRAND NEW.  The one note of caution that I would say is the smell is AWFUL.  Thankfully, we have an attic fan and a bathroom fan.  It took about 2-3 days before going into the bathroom didn't knock you out. :)  The installer cautioned not to use bathmats on the tub anymore, since they could suction up the coating I guess.  There are options for non-slip aids though.

"Marc did a fantastic job for us! We had two properties, a rental house in University City and a condo in Clayton and both had ugly and old tile in the bathrooms and kitchen. Marc was helpful and professional in seeing the projects right away, giving us written bids and helping us select the colors. He and his workers did a great job protecting the cabinets and walls and worked quickly and efficiently. Plus they were able to squeeze us into their schedule. The baths and kitchen look brand new! We also had the tile floors in the three bathrooms sprayed and our designer thought we had laid new tile!"

"I am extremely pleased with the job completed by Jason and his team. This team is professional and very attuned to detail. There were a few things, not related to the kitchen, that came up during the project, which I asked the team to address. They handled them and still were able to work on the kitchen project. The team worked up until they had to wait on the counter top installation; then, returned and finished the job. The job was started on 5/20/19 and was finished on 6/21/19. I highly recommend Honey Do's Solutions, which I have used for other projects."

"They will install any brand of water heater you wish, or sell you one that they carry. Person who did the install my heater did give me a heads up of problems with the unit I was buying. I ended up buying a different brand (not from the installer), and quite honestly am much happier with choice I made. Doing addition research did confirm the original concerns with my choice of product so it wasn't an issue of the installer trying to make a sale of his product."

"I am very, very happy with the beautiful job that Signature KB did in remodeling my kitchen and two bathrooms. Linda did a superb job at helping me design and visualize my project, sending me to great places, coming up with suggestion after suggestion when I was unsure of my options. Their choices for cabinets, hardware, faucets, countertop materials and the like were endless and I was very happy with where Linda sent me to pick out my appliances and granite. The contractor with which Linda worked, Thacker Construction, was very good, and very timely once the counter tops were ready to be installed. The reason for 4 stars as opposed to all 5 is that I had no idea that touch-up painting was not included. There were a lot of places where the wall that was newly exposed or created was either bare or had previous wall color/coverings, and I did not realize that the job was considered "completed" without the considerable amount of painting that needed to be done. I did suggest to Linda that that fact be shared with the client early on, so that no one is taken by surprise and left to their own devises! Other than that, I am entirely pleased and love living in and showing off my newly remodeled rooms!"

FAQs for plumbing installation for a remodel or addition projects in Portage-des-sioux, MO

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.
