Improve indoor air quality at the source
Air naturally moves from your crawl space or basement up into the rooms you live in, a process called the stack effect. If that below-grade air is humid, musty, or carrying mold spores, it becomes part of the air you breathe upstairs. Addressing the source below grade is often the most effective indoor air quality fix available.
Common problems we solve
- Musty smell noticeable in living areas, not just the basement
- Family members with allergy or respiratory symptoms that improve away from home
- Visible mold or high humidity in the crawl space or basement below
- HVAC returns located in or near an unsealed below-grade space
Benefits of a properly designed solution
Addresses the actual source
Sealing crawl space or basement air from living space stops contamination at the point of entry.
Reduces allergy and respiratory triggers
Cutting off musty, spore-laden air can meaningfully improve symptoms tied to indoor air quality.
Works with existing HVAC
Sealing and encapsulation reduce the amount of unconditioned below-grade air your system has to manage.
Whole-home benefit
Because the stack effect moves air throughout the house, a below-grade fix improves air quality on every floor.
