For homeowners, renters, homebuyers, landlords, property managers, and businesses in the Flathead Valley.

Mold does not always grow where it can be easily seen. It may be concealed behind walls, beneath flooring, inside cabinetry, around plumbing, or within materials affected by a past moisture problem.

Montana Mold Dogs combines professional inspection methods with a systematic search by Rex, our certified mold detection dog. Together, we provide a more focused investigation designed to identify areas of concern and help you determine the right next step.

Properties We Commonly Inspect in the Flathead Valley

The Flathead Valley includes older properties as well as significant newer residential development. Commercial properties are also within scope when appropriate. Geography and site conditions vary; not every property experiences the same water-entry risks.

Newer homes are often tightly constructed for energy efficiency. Older homes may have different roof, foundation, or repair histories. Both can benefit from an inspection that focuses on accessible areas and the specific history of the building.

A More Complete Mold Investigation

Rex, Montana Mold Dogs’ certified mold detection German Shepherd

We use established inspection procedures to evaluate the building and interpret Rex’s alerts in context.

Property History

The inspection begins with your concerns and the history of the building, including leaks, flooding, repairs, odors, previous testing, and the areas where concerns appear most noticeable.

Building and Moisture Assessment

We evaluate accessible conditions and look for moisture intrusion, water damage, material deterioration, ventilation concerns, and other conditions that may support mold growth. Moisture readings and thermal imaging are used where appropriate.

Systematic Canine Search

Rex searches accessible areas for mold-related odor, including locations where visible evidence may be absent. His alerts help identify areas that warrant additional attention. Rex is trained to detect odor associated with 18 mold species commonly found in buildings, including species that may produce mycotoxins.

Findings and Next Steps

We review the findings with you, document relevant observations and canine alerts, and explain the available next steps.

Depending on the findings, those steps may include targeted sampling, further investigation of a concealed area, correction of a moisture source, or consultation with a qualified remediation professional.

What a Canine Alert Means

A canine alert identifies a location associated with mold-related odor. It is an investigative finding—not a laboratory result.

An alert does not identify the mold species, measure the amount of growth, establish the extent of contamination, or determine medical risk. It helps us focus the investigation and recommend an appropriate next step.

When confirmation is needed, sampling can be directed toward a specific area of concern rather than performed randomly throughout the building.

Likewise, no canine alert does not guarantee that mold is absent. Inaccessible areas, unexamined materials, and the limitations of any inspection method must be considered when interpreting findings.

Rex’s search is systematic within accessible, safe, and agreed-upon areas. We do not open walls or remove flooring during the search.

Local Moisture Considerations in Kalispell and the Flathead Valley

The Flathead Valley receives somewhat more precipitation and snowfall than many other Montana cities, influenced by surrounding mountains and local geography. Spring snowmelt and winter attic conditions are relevant for many properties, but risks are property-specific.

Roof and attic moisture can occur from ice dams, snowmelt, or air leakage that allows warm indoor air to condense in colder attic spaces. Lower-level or crawl-space water entry can result from snowmelt, site drainage, or past flooding on certain properties. Flathead County floodplain information can be useful context for individual sites, but it does not apply uniformly across the valley.

In tightly constructed newer homes, indoor moisture from daily living or humidifiers can condense on cold surfaces if ventilation is limited. Older properties may have different pathways related to roof condition or foundation details.

Practical signs that may warrant an inspection include:

  • History of roof, attic, or lower-level water entry
  • Musty odors
  • Staining in accessible attic or basement spaces
  • Persistent window condensation
  • Concerns following spring snowmelt

An inspection evaluates the accessible evidence and reported history of the specific property rather than applying a single risk profile to the entire valley.
