No matter how immaculate your home may be, mold could be right around the corner. Literally.

As water evaporates and soaks into susceptible walls, ceilings, and carpets, mold growth can easily spread into the nooks and crannies of your residence, causing potentially serious health ramifications for your family.

If you’re a homeowner trying to take preventative measures against mold growth, DryHouse is here to help. Below, we’ve outlined the common reasons why that ugly black and green fungi is making its way into your home (and potentially your lungs), along with our recommended solutions on how to take the proper precautions and keep mold away for good.

Wet, Leaky Basement

If you live in an older home, there’s a good chance your drainage system has trouble keeping up with all the water intake or has failed completely. As a result, many residents experience flooding or wet basements, which can cause serious long-term mold growth if untreated. Standing water in a damp, humid basement will typically result in mold growth. To counter the issue, we recommend installing a basement waterproofing solution to prevent water coming through potential foundation cracks. Our waterproofing solutions are virtually impossible to penetrate, only allowing in one part per thousand – nearly 10x more effective than competitive solutions.

Indoor Plumbing Problems

Occasionally, the flooding noted above comes from indoor plumbing issues. With plumbing spiderwebbed throughout the walls of your home, leaky plumbing can cause serious mold issues if not treated immediately – mold behind walls, mold underneath carpets, etc. Whether the leaky situation is a long-standing issue or one-off problem, we recommend calling a plumber for an immediate fix. From there, consider long-term prevention via basement waterproofing or foundation waterproofing.

Roof Leaks

If you experienced a roof leak and fixed the problem… you potentially still have mold growth on the walls. While certain materials like drywall may need to be replaced altogether, mold on concrete walls can be removed with a thorough cleaning and future growth conceivably prevented with some crack repair.

Crawl Space

Imagine standing water, rodents, or mold in your basement. You would have that fixed immediately, right? If your home has a crawl space, it deserves the same priority as your basement. Thanks to moisture and soil gases coming up from the ground, crawl spaces are breeding grounds for high humidity. Ideal humidity levels are 40%, so consistent levels above 55% foster not only mold but pesky dust mite allergens as well. Since 40% of the air in your home comes from your crawl space, it’s clear as day that encapsulation is essential to not only maintaining a moisture-free environment but keeping the air in your home safe to breathe, too. If water is pooling or the floors are spongy, mold is knocking on your door. Before mold growth occurs, take preventative measures by installing a vapor barrier on the flooring and walls of your crawl space.

Specific Building Materials

When coupled with the variables above, certain building materials are moresusceptible to mold growth than others.
Mold on Wood

Have wood floors? Are they above a basement or crawl space that often gets damp or humid? Well, take precaution, because mold thrives off wood, soaking up the moisture in the material. Over time, the fungi will absorb all the nutrients in the wood and destroy its surface. Keeping the area clean and moisture-free is essential to maintaining wood surfaces. Implement moisture-prevention solutions underneath your wood floors with basement waterproofing or crawl space waterproofing.

Mold on Drywall

Since drywall is composed of water-absorbing elements, these sheetrock walls become hotbeds for mold growth. Maintaining even temperatures and a moisture-free environment are essential to keep drywall free of mold spores.

Mold Underneath Carpet

Ever lifted up old permanent carpet only to see those gross blackish green spots scattered underneath? Mold. When moisture absorbs into a carpet, or humidity rises from a damp basement, mold spores grow and tend to ruin the carpeting for good. To prevent mold growth on carpets, avoid accidental spills and take proper precautions to stop basement moisture from setting into the carpet, such as basement waterproofing or possibly even a foundation repair for flooding issues.

Mold on Concrete

Mold on concrete can become a serious problem, if not treated. Reason being, if there is water damage in a basement, the moisture will slowly absorb into the concrete walls over time, typically without homeowners knowing, until the problem is running rampant. To prevent mold growth on concrete in damp areas like your basement or crawl space, make sure to fix cracks in your concrete and keep the areas dry as possible.

Mold on Insulation

Because nearly every type of insulation can absorb water, they’re all common growth areas for mold. Moldy insulation should be replaced immediately. To prevent initial mold growth on insulation, keep the exterior around the walls dry as possible via solutions like basement waterproofing and basement crack repair. Additionally, closed-cell spray foam is an insulation option that isn’t as susceptible to mold growth.


Hot and cold temperatures, air temperature, and humidity play vital roles in mold growth.

While mold is commonly caused by the symptoms outlined above, weather plays a vital role in mold growth in homes, especially during the summer. During warmer months, humidity in the air is more prevalent than ever, creating the ideal environment for mold growth (typically, 77 to 86 degrees Fahrenheit). If walls are becoming noticeably moist, make an an effort to wipe them down. Additionally, keep indoor temperatures around the low 70s and humidity levels around 45% throughout the house.

If indoor air temperature is unregulated, humidity will rise, moisture will occur, and mold will inevitably grow. If your home has a crawl space where temperatures are difficult to regulate, consider vapor barrier installation to proactively prevent wall condensation.
