What Causes Mold Growth?

Mold thrives in damp, warm environments and often develops in areas with poor ventilation. Common causes include:
✔️ Leaky roofs, windows, or pipes
✔️ High humidity levels (above 60%)
✔️ Flooding or past water damage
✔️ Poor ventilation in bathrooms, kitchens, or basements

Where to Look for Mold

Mold often hides in areas you don’t see every day. Be sure to check:
🔹 Bathrooms – Around tubs, showers, sinks, and toilets
🔹 Kitchens – Under sinks, behind refrigerators, and near dishwashers
🔹 Basements & Crawl Spaces – On walls, floors, and insulation
🔹 Attics – Around vents, rafters, and under the roof
🔹 HVAC Systems – Inside air ducts or on vents

Signs of Mold Growth

Not all mold is visible. Here’s how to tell if you might have a problem:
✔️ Musty odors in certain areas of the home
✔️ Dark spots or discoloration on walls, ceilings, or furniture
✔️ Peeling or bubbling paint
✔️ Increased allergy symptoms (sneezing, coughing, itchy eyes) when indoors

How to Remove Mold Safely

If the affected area is small (under 10 square feet), you can often clean it yourself.

DIY Mold Removal Steps

1️⃣ Wear protective gear – Use gloves, goggles, and a mask to avoid inhaling mold spores.
2️⃣ Use a mold-killing solution – Mix:

  • 1 part white vinegar with 1 part water OR

  • 1 cup of bleach per gallon of water
    3️⃣ Scrub the area thoroughly – Use a brush or sponge on hard surfaces like tile, wood, and walls.
    4️⃣ Dry the area completely – Mold thrives in moisture, so ensure the area is fully dry after cleaning.
    5️⃣ Throw away contaminated materials – If mold has grown on carpets, drywall, or insulation, removal may be necessary.

When to Call a Professional

If you find large patches of mold, persistent moisture issues, or mold inside walls or HVAC systems, it’s best to call a mold remediation expert.

How to Prevent Mold Growth

✔️ Fix leaks immediately – Check plumbing, roofs, and windows regularly.
✔️ Control humidity – Keep indoor humidity below 50% with a dehumidifier.
✔️ Improve ventilation – Use exhaust fans in bathrooms and kitchens.
✔️ Use mold-resistant products – Consider mold-resistant drywall, paint, and insulation.
✔️ Clean and dry water spills quickly – Mold can begin to grow in as little as 24-48 hours.
