Willis Homes Mold Case Study Kansas City
Case Study Summary
This case study summarizes the Cleary family’s documented experience involving mold concerns, water intrusion and structural issues at their Kansas City area Willis Custom Homes property.
The Cleary family created Willis Homes Public Health Alert to share their experience, organize documentation and raise awareness for homeowners in the Kansas City area, including Overland Park, Johnson County and nearby Kansas communities.
This page shares one family’s documented experience. It does not claim that every Willis home has mold and it does not claim that other homes are affected without documentation.

Background
According to the family, they contracted with Willis Custom Homes to build their home at 16004 Cody in the Kansas City area. After a prolonged construction process, they moved into the home in April 2024.
The family states that after moving in, they began noticing water intrusion, structural concerns and moisture-related issues. By summer 2025, they say the first signs of mold were discovered. As the situation progressed, additional mold concerns were identified in other areas of the home.
The family states that mold was found in areas connected to all five children’s bedrooms.
This background is important because the family’s concern is not only about one visible issue. Their public alert centers on the pattern of water intrusion, mold concerns and structural issues documented after move-in.
Why the Family Created This Public Alert
The Cleary family says they created Willis Homes Public Health Alert because they felt other homeowners should understand how hidden mold and moisture concerns can develop behind finished surfaces.
As registered nurses and parents, they were especially concerned about the potential indoor environmental impact on their household.
The family’s goal is to document their experience, share what was found and encourage other Kansas City area homeowners to take repeated moisture concerns seriously.
The broader public health alert can be found on the Willis Homes Public Health Alert homepage.
Timeline of Concerns
The family states that they moved into the home in April 2024.
After move-in, they say concerns began involving water intrusion, structural issues and moisture-related conditions. At first, these concerns appeared to be isolated.
Over time, the family states that the pattern became more serious.
By summer 2025, the family says mold was discovered inside the home. They later reported that additional mold concerns were identified in other areas of the property.
The full timeline and family statement are available on the Cleary Family Story page.
Mold Concerns Documented by the Family
The family states that mold was discovered in the home in summer 2025 and that additional mold concerns were later identified in other areas of the property.
They also state that mold was found in areas connected to all five children’s bedrooms. This became one of the central reasons the family chose to share their experience publicly.
The family has shared photo documentation through Willis Homes Public Health Alert to show how mold concerns may appear in a newly built home and why hidden moisture should be taken seriously.

Water Intrusion and Structural Concerns
The family also documented water intrusion and structural concerns inside the home.
They state that moisture-related problems continued after move-in and became part of the larger concern surrounding the home’s indoor environment. Water intrusion is important because repeated moisture can affect building materials and may create conditions where mold can develop.
The family’s structural documentation includes concerns involving water intrusion, basement flooding and other construction-related issues observed inside the home.

Health and Safety Concerns
The family states that health and safety concerns contributed to their decision to leave the home.
Medical concerns should always be discussed with qualified health professionals. Mold exposure can affect people differently and symptoms can have many causes.
The Cleary family’s concern was shaped by their lived experience as parents and registered nurses. Their public alert focuses on what they say was documented inside their home and why they believe hidden moisture and mold concerns should not be ignored.

What This Case Study Does and Does Not Claim
This case study documents the Cleary family’s experience with their Kansas City area Willis Custom Homes property.

It does not make legal findings.
It is intended to share one family’s documented experience and provide public awareness around mold, water intrusion and structural concerns.
Why This Case Matters for Kansas City Area Homeowners
This case matters because many families in the Kansas City area, including Overland Park and Johnson County, rely on the assumption that a newly built custom home is dry, safe and free from hidden moisture concerns.
The Cleary family’s experience highlights why repeated water intrusion, musty odors, visible damage or unexplained indoor air quality concerns should be taken seriously, even in newer homes.
The purpose of this case study is not to create fear. It is to help homeowners ask better questions, document warning signs and seek qualified support when moisture
concerns appear.
