What Is Mold?
Mold is a moisture problem first. When building materials stay wet long enough, mold can grow and spread quickly through finishes, insulation, and HVAC-adjacent spaces.
Common warning signs
Visible staining, musty odor, repeated condensation, warped materials, and recent leaks are the most common homeowner signals.
What usually causes it
Roof leaks, plumbing failures, appliance overflows, poor ventilation, and crawl-space or basement humidity are common triggers.
What to do next
Document what you see, control the moisture source, and schedule an inspection if the scope is unclear or growth may be hidden.
Next step
Use this guide as a starting point, then compare local providers, inspection options, and project scope before spending money.
