"Look no further! Our kitchen remodel was top to bottom and even included tear-out of ceiling soffits. From the start: Pricing was competitive with an easy to understand estimate. Classic or trendy, Kristeen teaches at a local college and knows what’s out there and what we could expect. Communication was easy and prompt. Everyone was GREAT to work with and the job was completed ON TIME. They go ABOVE & BEYOND! Over a year after we were done our “Smart” faucet motor went out. At no charge, father and son came out and switched it out for us. We have done our share of remodeling and wish we had found them sooner. I LOVE my kitchen!"

"Isaacs is a true professional who obviously loves and takes pride in his work. He first provided a free estimate, coordinated a installation date with us, and arrived on said date on time and ready to go to work. When I suggested a different river rock than planned and an alternative supplier he had never worked with, Isaacs was very open to the suggestion and went to that source to ensure we were satisfied with the end result. He also suggested the material for the retaining wall which turned out beautiful. We plan on using Delgado Landscaping in the future and would recommend his company to anyone needing such work."

FAQs for addition to existing structure building service projects in Kansas City, KS

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.
