How Water Damage Leads to Structural Problems

Wood is a common framing material, and it soaks up water like a sponge. Once wet, wood fibers swell and then shrink as they dry. That repeated swelling and shrinking can crack boards, loosen nails, and pull joints apart.

Over time, wet wood rots. Rotting wood loses its strength and can't support the weight of your roof or floors. You might notice creaking floors, sagging beams, or doors that stick. If you catch the problem early, you can often dry the wood and save it.

Metal parts in your home, like nails, screws, and steel beams, can rust when they stay wet. Rust eats away at the metal, making it thinner and weaker. That can cause fasteners to fail and connections to loosen.

Corroded fasteners can pull out of wood, and rusted steel can lose its load-bearing ability. You might see rust stains on walls or floors, or notice that a railing or support feels wobbly. Replacing corroded metal is often part of the repair.

You don't need to be a builder to notice structural problems. Look for new or widening cracks in walls, ceilings, or the foundation. Doors and windows that suddenly stick or don't latch can be another clue.

Also check for floors that slope or bounce when you walk on them. If you see any of these signs, it's worth having a pro look. They can assess the damage and tell you what needs to be fixed.

• Cracks in drywall, plaster, or brick
• Doors or windows that jam or shift
• Floors that feel springy or uneven
• Gaps where walls meet ceilings or floors
• Visible water stains that keep growing
• A musty smell that doesn't go away
