What musty smell means in Julian
In Julian, musty smell is a moisture problem first and a cosmetic issue second. Julian water damage scope is shaped by elevation, age of housing stock, and weather. That local housing mix shapes where we look first when this symptom shows up.
Why musty smell shows up in Julian
Musty odor complaints in Alpine, Julian, and Mt. Laguna usually mean hidden damp material, not a dirty vent. With mountain cabins and rural homes with crawlspaces and septic, cavities and crawlspaces hide the source while cooler temperatures that slow dry-out keeps odor stronger.

Julian homes and what they need
