Understanding the Mold Removal Process


Mold thrives in dark, damp environments—and in homes or buildings affected by water damage, it can spread rapidly. At PuroClean, we specialize in professional mold removal in Granite City, delivering tailored solutions that address both surface mold and its underlying causes.

The mold remediation process begins with a comprehensive inspection. Our trained technicians identify the type of mold present, the source of moisture that’s fueling its growth, and the full scope of contamination. Once the affected areas are mapped out, we establish containment zones to prevent cross-contamination using negative air pressure and professional-grade barriers.

From there, we use safe, EPA-approved mold removal techniques to clean and treat surfaces, including hard-to-reach areas behind walls and under floors. Antimicrobial treatments help ensure that mold does not return. We also address moisture issues directly—whether it’s a leaky pipe, roof damage, or poor ventilation—to eliminate the risk of future growth.

When it comes to mold removal in Granite City, IL, trust PuroClean for industry-standard remediation practices, detailed post-remediation testing, and a team that truly understands how to restore a safe, healthy space.

Signs You Might Have Mold in Your Granite City Property


Mold isn’t always obvious. Often, it grows silently behind walls or beneath floors before making its presence known. That’s why it’s important to know the early warning signs—especially in a climate like Granite City, IL, where seasonal humidity and older infrastructure increase the risk.

Here are common indicators that you may need professional mold removal in Granite City:

  • Persistent musty or earthy odor
  • Discoloration on walls, ceilings, or baseboards
  • Peeling paint or bubbling drywall
  • Increased allergy or asthma symptoms indoors
  • Visible mold spots, often green, black, or white
  • Recent water damage or unexplained moisture

At PuroClean, we use moisture meters, infrared technology, and air quality assessments to detect mold growth early—even when it’s hidden from sight. Our goal is to stop the problem before it worsens.

If you notice any of these signs, don’t delay. Mold can weaken building materials, compromise air quality, and trigger serious health issues. Let PuroClean’s certified experts inspect your property and recommend an appropriate remediation plan.
