Unfortunately, your basement or crawl space is a perfect environment for biological growth.  It’s dark, damp, and often has poor ventilation.  Mold growth may be obvious, marked by dark or white patches visible on your walls, floors, or ceilings, or it may be hidden behind walls or under carpets.  

Even if you can’t see it, you can usually identify it by a musty smell. If left untreated, mold, mildew, bacteria, and other biological growths can lead to significant health problems for you and your family, so if you suspect you have mold in your home you need to act quickly.

Mold can impact almost all surfaces commonly found in your basement or crawl space, including drywall, wood, HVAC, pipes, drains and other finishes.

What Causes Biological Growth?

Drywall and insulation are especially susceptible to mold growth after a major water incident.  Wood framing, flooring, and furniture are also at risk of basement mold.  If you do not properly treat and remove mold from your home’s framing or flooring, you may face a serious and expensive problem later.  

Basements may flood from natural weather incidents or unexpected leaks, and carpeting is very difficult to properly dry.  When you’ve experienced a flood or other water-related incident, mold and mildew can grow even after you’ve drained and dried up all the water.

Mold may trigger minor allergic reactions, or pose a more severe threat to your family’s health and your home’s structural integrity.  The EPA recommends that if mold affects an area larger than 10 square feet, you should contact a professional. We can help you get rid of mold for good! Request a free in-home assessment on our website or give us a call.

Mold Removal & Biological Growth Prevention FAQs

What causes biological growth in basements and crawl spaces?

Excess moisture, warm temperatures, and organic surfaces. Local humidity and seasonal rains can exacerbate it.

What’s the long-term prevention plan?

Manage water (drainage/sump), isolate ground moisture (vapor barrier), seal pathways, and control humidity with a properly sized dehumidifier.

Do you “treat” existing growth?

We address moisture first, then follow appropriate surface cleaning/encapsulation steps. Your proposal outlines the safe, recommended approach.

How long does installation take?

Often 1–2 days, depending on space size and whether drainage or structural work is included.

Is it warrantied?
