The crawl space under a pier & beam home is out of sight, which is exactly why issues go unnoticed until they're serious.
Simple Maintenance
Keep the crawl space dry with good drainage and ventilation, watch for wood rot or pest activity, maintain consistent soil moisture, and have the beams and piers checked periodically.
The Payoff
Routine care catches small issues — a little rot, a shifting shim — before they become sagging floors and expensive repairs. It's the cheapest foundation work you'll ever do.
