Your home is a system, and all parts of the crawlspace affects the other. If you start to notice bouncy or sagging floors, it’s likely that your crawl space is losing support and is in need of repair. In most cases, the answer to crawlspace problems is to improve drainage, control moisture, remove wood rot, and provide additional support systems.

Three Common Crawlspace Problems
1) IMPROPER DRAINAGE
Without a proper drainage system, a crawlspace will hold water. If not addressed, standing water will cause the wooden structure to mold and rot and eventually weaken beams and joists. A depreciated wood structure may cause floors and subfloors to sag and your home may shift off the foundation. A proper drainage system prevents excess water from concentrating too close to the crawlspace.
2) IMPROPER VENTILATION
Ventilated crawlspaces allow ambient air to flow in and out. While the intent is to remove moisture from the crawlspace, the opposite can occur with a hot and humid climate. When the warm, humid air enters the crawlspace, it rises and accumulates below the home’s floor. If the home is air-conditioned and the floor uninsulated, condensation will often form on the wood structure. The underside of the subfloor will be affected by the moisture and eventually will mold and rot.
SYMPTOMS OF CRAWLSPACE MOISTURE PROBLEM:
• Mold or moisture damage in the crawl space or living area
• Musty odors or high humidity in the living area
• Buckled hardwood floors
• Insect infestations
• Rot in wooden framing members
• Condensation on air conditioning ductwork or equipment, insulation, water pipes
3) IMPROPER SPACING OF PIER COLUMNS
Pier columns throughout the crawlspace support the weight of the floors above. Improper placement of the columns puts extensive pressure on the beams and joists causing them to bend, sag, or bounce. Therefore, floors start to slope, causing cracks and other cosmetic problems in the home.
