What Are Crawl Space Joists?
Crawl space joists are the horizontal wooden beams that support your floors. They run across the crawl space, holding up the subfloor and everything above it. When these joists become damaged—due to water intrusion, rot, or pest activity—the floor above may sag, bounce, or feel uneven. This damage can also spread to other parts of the structure if not fixed promptly.
Our team assesses the condition of your joists and provides professional joist repairs or full replacements when needed to restore your home’s support system.
