If you've ever dealt with fungal growth in your crawl space, you know the typical solutions often come with their own problems.


Most treatments rely on harsh chemicals that fill your home with strong odors and leave you wondering what you're actually breathing in.


As someone who's worked in crawl spaces for years, I've seen how these aggressive chemicals affect both homes and homeowners.


People with breathing sensitivities often can't stay in their houses during treatment.


Even worse, some solutions are so harsh they can actually damage the wood they're supposed to protect.

Watch What Happens When Science Meets Fungus

Here's something fascinating about our approach: we use a hydrogen peroxide-based solution that specifically targets fungal growth while leaving healthy wood untouched. Let me show you how it works.



When we spray this solution on clean wood, nothing happens. But the moment it hits fungal growth, you'll see an immediate reaction - it starts to foam and oxidize. That foaming action isn't just for show - it's actually eating away the fungus, leaving behind clean, healthy wood.


Within minutes, you can see the difference. The fungal growth disappears, and what's left is clean wood that's been restored to its natural state. No harsh smells, no dangerous chemicals, just a simple scientific reaction that gets the job done right.

Why This Method Works Better

The science behind our treatment is actually pretty simple. When the hydrogen peroxide solution meets fungal growth, it creates a targeted oxidation reaction. Think of it like a smart bomb that only attacks the problem, leaving everything else alone.



What makes this approach special is how precise it is. On clean wood? Nothing happens. But hit a spot of fungal growth, and you'll watch it foam up and disappear. No guessing if it's working - you can literally see it happening right in front of you.

What Sets Our Treatment Apart

After testing countless products over the years, this solution stands out for three key reasons:

  1. Zero harsh chemical smells
  2. Safe for people with breathing issues
  3. Shows results immediately



You don't have to take my word for it - I can demonstrate the difference right on the spot. Spray, watch it foam where there's fungus, and within minutes, you're looking at clean wood.

You've probably noticed it - your crawl space dehumidifier runs constantly. The tank fills up, the unit kicks back on, and the cycle never stops. But when you check on things, your crawl space still feels damp. There's still that musty smell. And you're left wondering if the equipment is actually doing anything.

When I first inspected this crawl space in Knoxville back in late summer, the AC condensate pan was completely full of water - right up to the drip line. Water was constantly dripping onto the wood joists below, creating a moisture problem that had been going on for who knows how long.

Just wrapped up a job here in Knoxville where the homeowners had been using their crawl space for storage. Holiday decorations, clothes, family keepsakes - all the stuff you want to keep but don't use every day.
