In this blog, we'll look at whether water damage can cause mold growth and how to properly address the issue, keeping your home safe, healthy, and mold-free.

Can Bathroom Water Damage Lead to Mold?

Bathroom water damage creates an ideal environment for mold growth, as mold thrives in moist, humid conditions commonly found in bathrooms.

Mold spores, which are constantly present in the air, settle on damp surfaces and begin to grow within 24-48 hours (approximately 4 days).

Common Signs of Mold from Water Damage:

• Must smell in the bathroom.

• Flaking paint or wallpaper that lifts or blisters.
• Warped floors or tiles.
• Ongoing issues like coughing, sneezing, or allergy flare-ups.
