The Off-Gassing Timeline
New home off-gassing is most severe in the first six months to two years after construction. During this period, chemical concentrations in indoor air are at their highest. This is the period when families are most excited about their new home, spending the most time in it, and often moving in with newborns or young children.
After two years, off-gassing slows but does not stop. Formaldehyde continues releasing from pressed wood products for 20 years or more. Chemical flame retardants migrate continuously from furniture and carpet padding into house dust for the life of the material.
Who Is Most at Risk
Children breathe more air relative to their body weight than adults and spend more time close to floors where heavier VOCs and flame retardant chemicals in dust concentrate. The EPA and CDC have both documented that children's developing neurological systems are disproportionately affected by VOC and formaldehyde exposure.
Pregnant women and their unborn children face documented risks including preterm birth, low birth weight, and fetal developmental effects from formaldehyde and endocrine-disrupting chemicals. Families with asthma or respiratory conditions face immediate health impacts from the VOC and particulate burden in new construction indoor air.
What to Do
The most powerful thing you can do before moving into a new home is have it tested. Our Healthy Home Assessment identifies every toxic material category in the home, measures air quality, and delivers a prioritized plan for replacement.
For homeowners building new, the answer is specification:
- Specify GaiaCrete® and hemp fiber batts instead of spray foam and fiberglass
- Specify natural lime plaster instead of drywall
- Specify VOC-free mineral paints
- Specify solid wood flooring
- Specify formaldehyde-free cabinetry
Every specification decision is a health decision for your family.
The new home smell does not have to be part of the experience. It only is because the industry has never been asked to do better. Mr Hemp House exists to change that.
