Attic & Basement Mold Remediation in Sioux Falls, SD

Attics and basements are the most common locations for mold growth in Sioux Falls homes — and the easiest to ignore until the problem is severe. Poor ventilation, temperature swings, and moisture buildup in these areas create ideal conditions for mold colonies to thrive undetected for months or even years.

Attic Mold Remediation

Sioux Falls attics are especially vulnerable during winter when warm indoor air meets cold roof decking, causing condensation. Ice dams — common in South Dakota — force melting water under shingles and into attic insulation. Our attic remediation process includes:

• Insulation Removal & Replacement — We remove contaminated insulation and install mold-resistant materials.
• Ventilation Improvement — We install or repair ridge vents, soffit vents, and attic fans to reduce humidity.
• Roof Leak Repair Coordination — We identify and document roof damage so your roofer can fix the source.
• Wood Treatment — Framing and sheathing receive antimicrobial treatment to prevent regrowth.

Basement Mold Remediation

Basements in Sioux Falls are prone to moisture due to high water tables, poor exterior drainage, and lack of airflow. Summers bring humidity that condenses on cool basement walls. Our basement remediation includes:

• Moisture Barrier Installation — Vapor barriers on walls and floors stop groundwater migration.
• Dehumidification Systems — We recommend and install basement dehumidifiers sized for your space.
• Foundation Crack Sealing — We seal cracks and joints that allow water intrusion.
• Structural Damage Repair — Rotting sill plates, rim joists, and subflooring are replaced with treated lumber.
