Crawl Space Moisture Control in Tallahassee, FL


Crawl space moisture almost always comes from one of four places: the soil, humid outside air, water finding its way under the home, or a plumbing or condensate leak. Treating the wrong one is how homeowners end up spending money and still smelling must.

Moisture control starts with figuring out which source is driving the problem in your home, then correcting it in the right order.

Standing water and torn plastic sheeting on the damp soil of a vented crawl space

The four common sources


  • Ground moisture evaporating from uncovered or poorly covered soil
  • Humid outside air entering through vents and openings and condensing on cool surfaces
  • Surface or subsurface water entering the crawl space after rain
  • Leaking supply lines, drain lines, or HVAC condensate lines

What homeowners usually notice first


  • A musty smell that shows up in the house, not just under it
  • Condensation or rust on ductwork, strapping and pipes
  • Insulation sagging or falling away from the subfloor
  • Damp, dark soil or visible water under the home
  • Floors that feel spongy, cool or uneven

How we approach it


An inspection documents moisture conditions, the state of any existing barrier, drainage around and under the home, ventilation, insulation and signs of past water. From there the plan is ordered so each step supports the next: stop water first, cover the ground, control the air, then verify humidity stays where it should.

We report what we find, including when the fix is smaller than you expected.
