Signs of Mold in Your Home and what Causes It

While this does sound scary, the professionals at Green Home Solutions are ready to help with mold remediation services . Give us a call if you notice any of the following signs of mold in your home:

• You can see it: Even a small patch of mold on walls, ceilings, or floors can indicate a larger problem. Because mold feeds on organic or porous substances and can grow on the cellulose component of drywall and wood, it often lurks inside walls or ducting, in crawl spaces, and even underneath a structure where you can’t actually see it.
• You can smell it: A musty, stale odor is often strong evidence that mold exists somewhere in your property. The hidden source of the odor must be found and identified so that it can be thoroughly eliminated.
• You can feel it: Exposure to mold can cause mildly annoying symptoms in some people, while others may experience symptoms that compromise their well-being, depending on the person’s susceptibility to mold’s toxicity.

Causes of Mold in Basements and Crawl Spaces

Basements and crawl spaces have all of the right conditions for mold, so it’s very important to control moisture with a good dehumidifier year-round. In addition to moisture control, keep an eye out for places water can enter your home, and try to keep clutter to a minimum where possible. Here are our top checklist items for mold causes when we do a visual assessment:

• High humidity
• Dirt/unfinished floor
• Undersized, unused, or no dehumidifier at all
• Clutter that eliminates air flow
• Cardboard boxes that absorb moisture
• Unsealed or non-operating sump pumps
• Off-gassing from new construction materials
• Foundation wall and floor cracks that leak after storms
• Insufficient crawl space ventilation or vapor barrier

Causes of Mold in Living Spaces

Living spaces such as bedrooms, living rooms, kitchens, and especially laundry rooms and bathrooms can all support mold growth. Be on the lookout for signs of mold from issues like:

• Leaks around windows and doors due to wood rot, caulking cracks, and faulty installations
• High-humidity rooms such as laundry rooms and bathrooms that aren’t ventilated properly
• Leaks from refrigerator ice maker lines and dishwasher and washing machine connections
• Lack of exhaust ventilation in areas of high humidity such as kitchens and bathrooms
• General plumbing leaks

Exterior Causes of Mold

You may not think about it very often, but the exterior of your home is something you should check out a couple of times each year. Looking for signs of water damage and anything else from the list below can help you take control of a mold issue fast:

• Roof leaks and flashing issues
• Improper grading
• Clogged gutters and downspouts not discharging water away from the building
• Lawn sprinklers too close to the building
• Gaps around electrical fixtures and pipes penetrating the exterior skin
• Leaks around windows and doors due to wood rot, caulking cracks, and faulty installations

Any of the factors above can lead to your house becoming a home for mold too. Take a few minutes to look for these conditions in key areas in your house. We recommend examining your home’s basement, exterior, and attic at least once a year to look for new issues that may have been caused by weather.
