MOLD TESTING IN
SOULARD, MO

Historic Stone Foundations

The Challenge: Many Soulard buildings sit on limestone or sandstone foundations from the 1840s-1900s. These porous materials absorb Mississippi River moisture and groundwater, creating persistent basement dampness.

Common Issues: White efflorescence on stones, musty basement odors, mold growth on floor joists above stone walls, moisture wicking up into first-floor walls.

What We Do: Non-invasive moisture mapping of historic foundations, air quality testing in basements, identification of mold species that thrive in stone basement environments, documentation for preservation work.

Brick Rowhouse Moisture

The Challenge: Soulard's signature brick rowhouses have shared walls, limiting airflow and ventilation. Original lime mortar can deteriorate, allowing water penetration between units.

Common Issues: Mold growth on shared walls, basement moisture migration between connected properties, poor cross-ventilation, water intrusion through deteriorated mortar joints.

What We Do: Shared wall moisture assessment, ventilation evaluation, thermal imaging to locate water intrusion points, air sampling in poorly ventilated spaces, coordination with multi-unit moisture issues.

Riverfront Humidity

The Challenge: Soulard sits just blocks from the Mississippi River. Humid air from the river increases indoor moisture levels, especially in summer months when warm, moist air contacts cooler historic walls.

Common Issues: Condensation on walls facing the river, increased humidity in poorly insulated buildings, mold growth in corners and behind furniture, musty odors intensifying in summer.

What We Do: Humidity monitoring throughout the property, identification of condensation-prone areas, recommendations for dehumidification that work with historic buildings, seasonal moisture pattern analysis.

Old Ventilation Systems

The Challenge: Historic Soulard homes often lack modern ventilation. Bathrooms without exhaust fans, kitchens with poor airflow, and minimal fresh air circulation create moisture buildup.

Common Issues: Bathroom mold from inadequate ventilation, kitchen moisture accumulation, stale air in closed-off rooms, mold growth in closets and cabinets.

What We Do: Ventilation assessment respecting historic architecture, identification of high-moisture areas needing airflow, practical ventilation recommendations that don't compromise building character.

Shared Wall Concerns

The Challenge: Connected rowhouses mean moisture problems can migrate between properties. A neighbor's plumbing leak or moisture issue can affect your shared walls.

Common Issues: Mold appearing on shared walls from adjacent properties, coordinated moisture issues across multiple units, difficulty isolating moisture sources when walls are connected.

What We Do: Thermal imaging of shared walls, moisture source identification, documentation for multi-property coordination, neighbor-friendly testing approaches, liaison with property managers for connected buildings.

Market District Commercial Properties

The Challenge: Soulard Market area buildings combine commercial and residential uses. Restaurants, shops, and bars create unique moisture loads in historic structures not designed for these purposes.

Common Issues: Commercial kitchen moisture affecting upper residential units, grease buildup retaining moisture, high-traffic commercial spaces with inadequate ventilation, moisture from refrigeration equipment.

What We Do: Commercial mold testing for mixed-use properties, assessment of commercial moisture impacts on residential areas, coordination with business operations, code-compliant testing for commercial tenants.
