Bathrooms are naturally high-moisture environments, and it’s common to find small areas of mold or mildew in showers and around bathtubs. This course is designed to empower homeowners and renters with the knowledge and confidence to safely address minor mold issues without professional intervention — while ensuring that no hidden or larger problems are overlooked.

Participants will learn how to properly inspect surrounding areas for signs of deeper moisture damage, safely remove discolored caulking and grout, clean affected surfaces, and apply mold-resistant repairs to help prevent future growth. Clear guidance is also provided for recognizing when professional evaluation or additional support is needed.

By the end of this course, students will feel equipped to take action to improve indoor environmental health, protect their homes, and respond early to any potential concerns.
