Longmont — Frequently Asked
Are there still effects from the 2013 Longmont flooding in homes today?
Yes — chronic moisture issues and foundation settling related to the 2013 flood are still present in some homes, particularly those near the St. Vrain corridor that experienced significant water intrusion. Homes that were flooded and incompletely dried have higher long-term mold risk. A professional moisture assessment can identify lingering issues.
