Water Damage and Mold Go Hand in Hand
Most people don’t realize how quickly mold can take hold after water damage. Within 24 to 48 hours of a leak, flood, or moisture intrusion, mold spores can begin to colonize walls, flooring, and structural materials. At St. Louis Demolition Company, we handle both water damage restoration and mold remediation, so you’re not left coordinating between multiple contractors while the problem gets worse. One call covers it all, from drying out the damage to making sure mold never gets a foothold.
The Health Risks of Mold Exposure
Mold is more than an eyesore, it’s a genuine health concern for anyone spending time in an affected space. Prolonged exposure to mold spores can trigger respiratory issues, persistent coughing, nasal congestion, headaches, and worsening allergy symptoms. Children, the elderly, and anyone with asthma or a compromised immune system are especially vulnerable to the effects of mold in the home.
The tricky part is that mold doesn’t always announce itself. It can grow behind drywall, under flooring, and inside HVAC systems long before it becomes visible. If you’ve recently dealt with water damage, a musty smell, or unexplained health symptoms in your household, mold may already be present. St. Louis Demolition Company can assess your property and address the problem before it gets worse.
Our Mold Remediation Process
Every job starts with a thorough inspection of your property. We identify the extent of the mold growth, locate the moisture source behind it, and determine the best course of action before any work begins.
Before removal starts, we contain the affected area to prevent mold spores from spreading to other parts of your home or business. This protects your property and keeps the remediation process controlled.
Our team safely removes all mold-affected materials and treats surfaces with professional-grade products to eliminate spores at the source. We don’t just clean the surface, we address the problem completely.
Once removal and treatment are complete, we thoroughly clean the space and haul away all debris. We leave your property clean, safe, and ready for whatever comes next.

Mold Remediation FAQ
Mold removal refers to physically cleaning or removing visible mold from a surface. Mold remediation is the full process, from identifying the source, containing the affected area, removing the mold, treating surfaces, and preventing it from coming back. Remediation addresses the root cause, not just what you can see.
Most residential mold remediation jobs take anywhere from one to five days, depending on the size of the affected area and the extent of the damage. We’ll give you a clear timeline after our initial assessment so you know exactly what to expect.
Not if the moisture source is properly addressed. Mold needs moisture to grow, so as long as the underlying cause — a leak, humidity issue, or water intrusion — is resolved as part of the remediation process, the mold won’t return. That’s why our process always starts with identifying and addressing the source.
Common signs include a persistent musty smell, visible dark spots on walls or ceilings, recent water damage or flooding, and unexplained allergy or respiratory symptoms in household members. If you’re noticing any of these, it’s worth having a professional take a look.
