Don't Let This Common Mistake Get You

WHEN CONTRACTORS CUT CORNERS, THE HOMEOWNER LOSES!

Running a dehumidifier in an unsealed crawl space is like trying to cool your house with the front door wide open.


You're wasting energy, wearing out expensive equipment, and fighting a battle you can't win.


Here in the Lowcountry, we see this problem all the time.


Homeowners invest in quality dehumidifiers for their crawl spaces, but missing one small detail can make that investment work harder than it needs to.


As a crawl space specialist who's been under thousands of local homes, I can tell you - these small gaps are costing you money every single day.

Why This Matters to Your Home and Wallet

When your crawl space isn't properly sealed, your dehumidifier is trying to dry out more than just your crawl space - it's trying to dry out the whole neighborhood.


This means:

  • Your dehumidifier runs constantly, driving up electric bills
  • Equipment wears out years before it should
  • Your crawl space never gets truly dry
  • You're risking expensive floor damage from constant moisture


The worst part? Most homeowners don't even know this is happening until they get hit with high power bills or equipment failure.




The Problem in Detail

You'd be surprised how often we find these unsealed gaps in Lowcountry crawl spaces - even in homes where other companies have already done work. They're usually around pipes, vents, or utility entrances. Sometimes they're obvious, but more often they're tucked away in corners or hidden behind equipment.


These gaps might seem small, but they're constantly letting in outside air. Your dehumidifier, which should only be managing the moisture in your sealed crawl space, is now fighting against an endless stream of humid Charleston air.

The Solution

Fixing this issue is straightforward, but it needs to be done right.


Here's our proven method:

  • Cut rigid foam board to fit the gap exactly
  • Secure it firmly in place
  • Add hardware wire as a barrier against rodents
  • Seal everything with professional-grade spray foam


This combination gives you a lasting seal that stands up to our coastal climate while keeping pests out of your crawl space.

What Every Homeowner Should Know

Your dehumidifier might be struggling if:

  • It runs constantly without breaks
  • You hear it working harder than usual
  • Your crawl space never feels quite dry
  • Energy bills are creeping up month after month


Getting a professional inspection is crucial because these issues often hide in spots most homeowners never see.


The good news?


Once properly sealed, your system will work more efficiently, last longer, and keep your crawl space genuinely dry.


The fix typically takes less than an hour, but it can add years to your equipment's life and significantly cut your power bills.


It's the kind of small detail that makes a big difference in how well your entire crawl space system works.

When I'm not under houses solving moisture problems, you might find me on the jiu-jitsu mats getting schooled by someone better than me. Why? Because I believe that excellence comes from constantly learning, whether that's in martial arts or crawl space work.

When someone tells you their crawl space is "finished," that can mean a lot of different things. Sometimes it means properly encapsulated and protected. Other times - like what we found in this historic downtown Charleston home - it means corners were cut and problems were covered up instead of fixed.

I just spent my morning scraping debris off a crawl space vapor barrier with a sharp metal shovel. Why? Because we're replacing another company's failed encapsulation system. Here's the thing - our 120 mil material didn't even scratch. Try that with the thin stuff most companies use, and you'll be looking at shreds.
