How Long Does It Take for Water Damage to Show Up?
Whether from a burst pipe, storm, or slow leak, water damage can begin within hours. The longer it goes untreated, the more severe the damage—and cost. At Purisync Heating and Air, we help homeowners in Kirkwood and surrounding areas understand how fast water can destroy materials, lead to mold, and weaken a structure.
What Happens in the First Few Hours?
- **0–1 Hours:** Water begins soaking into porous materials like drywall, carpet, wood, and insulation.
- **1–24 Hours:** Stains, warping, and paint bubbling may begin. You might notice a musty odor.
- **24–48 Hours:** Conditions become ideal for mold growth. HVAC systems and wiring may begin corroding.
When Does Mold Start Growing?
Mold can begin growing in as little as 24–48 hours if moisture is not dried properly. Mold spores thrive in damp, warm, dark places—like wall cavities, basements, and under carpets.
