Common crawl space problems in Des Moines
Musty smell
Des Moines gets 36.55 inches of rain and snow each year. That moisture comes up through dirt floors or crawls in through open vents. The smell means humidity is too high.
How to fix itStanding water
Iowa winters (January lows average 13.8°F) and a 42-inch frost line mean freeze-thaw cycles push water toward foundations. Poor grading or broken downspouts make it worse.
How to fix itMold on wood
Mold grows when humidity stays above 60%. You might see it on floor joists, insulation, or the sill plate. Encapsulation keeps the space dry enough to stop new growth.
