Mold is a very common side effect of having moisture issues in your basement. The growth of mold is caused by too much moisture build-up and not enough ventilation. Not only is it unsightly in your basement, but it can also lead to health issues. Mold ranges from several different colors like grey, black, green or white, and some can even be toxic.

Foundation Cracks

Concrete foundation cracks are very common in basement walls, be it stacked (cinder block), or poured. Cracking typically occurs when the concrete dries, or from any settlement in the soils on the exterior of the foundation. Cracks create passageways for water to seep into your basement, and water will always follow the path of least resistance. Even the smallest of cracks can allow water to flow through, so it’s important to get these checked out before the issue worsens.

Tie Holes

If you notice any tie holes in your concrete foundation, these could also be passageways for water to get through to your basement. These are very small holes that are left behind when the steel rods are removed after the concrete is initially poured. These holes are patched, but over time they are susceptible to leaks if not patched properly.

Water Stains

Although this may seem like the most obvious, some water stains aren’t as obvious as you’d think. Aside from stains on the floor, water stains can also appear at the top of the basement wall from roof runoff. Water stains can appear on painted or concrete walls, which will be dark. They can also appear as efflorescence, which looks like a white, powdery/chalky substance on your walls.

Extra Pests & Bugs

Basements are breeding grounds for bugs and pests. They love to live in dark, damp spaces, so if you notice any unwanted guests in your basement, it could be a sign of moisture or high humidity issues.

Water can enter your basement in several different ways, so it’s important to look out for these symptoms in your basement to avoid potential water damage:

  • Cracks in your foundation
  • Window leaks
  • Floor cracks
  • Wall cracks
  • Excess moisture in walls or window sills

Water can easily seep through any open cracks or leaks in your basement, so it’s a good idea to monitor your basement regularly to keep an eye out for those susceptible places. Our waterproofing experts at Foundation Recovery Systems can waterproof your basement to ensure water stays out, permanently.

Basement moisture issues can be solved quickly and permanently if caught early enough. During the humid months in Missouri, your house is often even more susceptible to water damage. If you think your house needs an inspection, let us know!
