How Wildfire Burn Scars Affect Flash Flood and Mold Risks

Apr 25

Colorado’s natural beauty comes with natural risks—including wildfires. And while the immediate threat of a wildfire is well understood, many homeowners in Colorado Springs and surrounding areas don’t realize what comes next: increased flash flood risks and hidden mold problems, especially in and around burn scar zones.

At Colorado Water & Mold Restoration, we help homeowners deal with the after-effects of water damage and mold growth—and that includes the lesser-known consequences of wildfire activity.

Let’s break down why wildfire burn scars significantly increase the risks of flooding and mold, and what you can do to protect your home.

🔥 What Is a Burn Scar?

A burn scar is the area of land that remains after a wildfire has passed through. These areas may appear charred and barren, with little to no vegetation left. The soil in a burn scar becomes:

Hydrophobic (repels water)
Compacted and hardened
Stripped of plant life that would normally absorb rain

Because of these changes, rainfall can’t properly soak into the soil, leading to excessive runoff—and in many cases, flash flooding.

🌧 Why Flash Flooding Is Common After Wildfires

Burn scars significantly increase the risk of flash floods, especially during Colorado’s monsoon season or intense afternoon storms. Here’s why:

Water runs off too quickly and can't be absorbed
Debris flows (mud, rocks, ash) clog drainage systems
Nearby creeks and rivers can overflow within minutes
Rainfall that would normally be harmless becomes dangerous

Even if your property wasn’t affected by the fire itself, living downhill or downstream from a burn scar puts you at risk for sudden flooding.

🦠 How Burn Scars Contribute to Mold Risk

Flash floods aren’t the only concern. Floodwaters rushing down from burn scars often carry soot, ash, and organic debris that infiltrate basements, crawl spaces, and wall cavities—creating the perfect environment for mold growth.

Here’s how wildfire-related flooding can contribute to mold:

Moisture intrusion into hidden areas goes unnoticed
High humidity and organic material encourage mold growth
Soot and ash particles act as food sources for mold
Muddy floodwater is difficult to fully clean without professional help

If not addressed quickly, mold can begin growing within 24–48 hours after flooding.

🏡 How to Protect Your Home After a Nearby Wildfire

If your home is near or downhill from a recent burn scar, here are steps you can take:

✅ 1. Know Your Risk Zone

Use local resources (like the Colorado Springs Fire Department or NOAA flood maps) to check if you’re near a burn scar or in a flood-prone area.

✅ 2. Prepare for Flash Flooding

Install sump pumps and backflow valves
Keep gutters and downspouts clear
Create drainage channels or French drains
Consider sandbags or temporary barriers during heavy rain

✅ 3. Inspect for Water Damage After Storms

After a significant rain event, look for signs of moisture intrusion, including:

Musty odors
Water stains
Warping floors or baseboards
Damp drywall or flooring

✅ 4. Schedule a Professional Mold Inspection

If you’ve had any water intrusion, especially from runoff or flash floods, it’s best to get a professional mold inspection. Mold can grow out of sight and spread quickly, affecting both health and structural integrity.
