Not every wet spot needs a contractor. But guessing wrong in the South Florida climate is how a small leak becomes a wall full of mold. Here is an honest line between what you can handle and what you should not.

You can often handle it yourself when: the water is clean (from rain, not sewage), the area is small, you caught it within hours, and you can fully dry it and confirm the wall cavity behind it is dry too. A small, fresh, fully dried spot is usually fine.

You should call a professional when:

• The water sat for more than 24 to 48 hours
• There is a musty odor, which points to growth you cannot see
• Water spread behind walls, under flooring, or into the AC system
• The water was contaminated
• The affected area is larger than a small patch
• Anyone in the home is sensitive to mold or air quality

Why the line matters in Florida. Mold remediation is a licensed activity in this state, and for larger jobs that licensing protects you. A Certified Mold Remediator follows a containment and removal process that keeps spores from spreading to clean parts of the home, something a shop vac and bleach cannot do. The documentation also supports your insurance claim.

The honest version: if you are asking whether it is too big to DIY, it usually is. An inspection costs far less than tearing out and rebuilding a wall you dried on the outside but not the inside.
