Work was completed in less than the time specified and the installer, Aaron was great to work with. Had a problem with the toilet after three months and they were great about coming back to fix it. The fix didn’t work though and instead of messing with another repair, they just replaced it with a brand new one. We would definitely recommend this company."

Family owned & operated for 35 years. 3 employees. Additional contact name - Judy and Michael Banter.

"It was excellent! Our family could not be anymore satisfied with Mike and Judy's professional guidance and attention to detail, for our total kitchen remodeling. We are a family of five and Mike worked daily, persistently, to get us back into our kitchen. Everything went smoothly, ordering cabinets and countertops, flooring and tile .We were impressed with Mike's cleanliness. He would sweep and organized his tools and have everything he used for the day put up and out of our way. Mike has an eye for detail. Our family could not be any happier with our new, beautiful, modern kitchen, thanks to Mike and Judy Banter! We would highly recommend them!!"

FAQs for addition to existing structure building service projects in Knightstown, IN

Converting an existing space into a laundry room is more affordable than building a new addition. While new additions start at $5,000, renovating an existing space for laundry use can begin at $1,300. 

Your specific costs will depend on whether plumbing and electrical connections exist nearby, the quality of finishes you select, and whether any structural modifications are needed. Always budget extra for unexpected issues, particularly in older homes where hidden problems might surface during renovation.

The smallest practical size for a new laundry room addition is 35 square feet, which provides enough space for basic appliances and minimal storage. For renovations utilizing existing space, smaller footprints might work with space-saving solutions like stacked appliances. 

A standard-sized laundry room of 60 square feet offers more comfort and functionality, allowing for counter space and storage cabinets. The optimal size depends on your household needs and available space.

Yes, adding a laundry room requires several permits, particularly for new additions. You'll need building permits, plus specific permits for electrical work, plumbing installations, and possibly HVAC modifications. 

Requirements vary significantly by municipality, so consulting with your local building department before starting work is essential. Proceeding without proper permits can result in fines, mandatory removal of completed work, and complications when selling your property.

The timeline for completing a laundry room addition varies based on project complexity, contractor availability, and permit processing times. Factors that can extend the schedule include material delivery delays, weather conditions, and unforeseen structural issues discovered during construction. 

Renovating an existing space often requires less time than building a completely new addition. Working with an experienced contractor who can coordinate various tradespeople efficiently helps keep your project on schedule.
