Expert Mold Inspection & Testing in Caledonia, MN
Caledonia is a city of striking beauty, perched on the edge of the Driftless Area where the rolling farmland meets deep, forested valleys. While our high ridges offer some of the best views in Houston County, the humid summers and the rugged geography of the region can lead to significant moisture challenges for local properties.
At MD Mold, we provide professional, unbiased mold inspection and testing services designed to protect the historic integrity and modern safety of Caledonia homes and businesses.
A Gateway to the Driftless
Caledonia’s history is a story of pioneering spirit and community strength. Founded in 1853 and named by Scottish settlers after the Latin name for Scotland, the city has long served as the heart of Houston County. Our downtown and residential streets are a living timeline of Midwestern growth.
Our local history is preserved by the Houston County Historical Society, which maintains a sprawling museum complex that includes:
The Historic Houston County Jail: Built in 1875, this stone structure is a remarkable example of 19th-century institutional architecture.
The Agriculture Museum: Celebrating our deep roots in dairy and crop farming that have sustained the region for generations.
St. Mary’s Catholic Church: A breathtaking example of stone craftsmanship that stands as a landmark on the city's skyline.
Just as the community works to preserve these historic stone and timber structures from the elements, we work to protect your home from the biological threats that thrive in damp, unventilated spaces.
Why Caledonia Properties Face Mold Risks
Caledonia’s location on a high ridge surrounded by deep valleys creates unique atmospheric conditions that can impact your indoor air quality.
Valley Fog & Humidity: Warm, moist air often gets trapped in the surrounding coulees and valleys, leading to high ambient humidity that can seep into basements and crawl spaces.
Limestone Seepage: Much of Caledonia is built over a limestone base. During heavy rains or spring thaws, water can migrate through the porous rock and enter older foundations, creating a persistent "wicking" effect.
Historic "Ridge" Homes: Many of Caledonia’s most beautiful homes feature original wood framing and plaster. Without modern vapor barriers, these organic materials can easily absorb moisture and host mold colonies if a leak or humidity spike occurs.
Our Professional Testing Protocol
We provide a scientific, non-invasive approach to mold detection. We do not perform remediation, which ensures our findings are completely objective.
ServiceImportance for Caledonia ResidentsInfrared Moisture MappingWe detect hidden leaks and "cold spots" behind walls without damaging historic plaster or modern finishes.Airborne Spore AnalysisWe compare indoor air quality to the local outdoor baseline to identify elevated levels of toxic or allergenic molds.Foundation & Masonry ChecksFocused inspections of stone and concrete foundations to ensure "ridge-top" runoff isn't fueling growth.Relative Humidity MonitoringWe use precision hygrometers to identify "at-risk" zones in your home where mold is likely to activate.
Local Insight: If you’ve noticed a "musty" smell in your basement after a heavy rain or during the muggy harvest season, it’s likely an indicator of active moisture. In the Driftless region, early detection is the key to preventing permanent structural rot.
