The bottom of your wall, right above the baseboard, looks puffy or distorted. The paint is bubbling, the drywall feels soft, and the baseboard may be pulling away from the wall. Drywall swelling near the baseboard is a classic sign of moisture intrusion from below—from a floor leak, basement moisture, dishwasher leak, or toilet leak. The moisture wicks up the drywall from the bottom, causing the gypsum to swell and the paint to bubble.
This type of damage is common in Chicago homes, especially in bathrooms, kitchens, and basements where water sources are close to the wall floor junction. The damage often goes unnoticed until it becomes significant, because the baseboard hides the lower portion of the wall.

Common Causes of Bottom Wall Moisture Damage
Toilet leak. A leaking toilet wax ring or supply line causes water to pool at the base of the wall, soaking the bottom inches of drywall.
Dishwasher leak. A leaking dishwasher hose or pump causes water to run along the floor and soak the adjacent wall bottom.
Basement moisture. In basements, ground moisture wicks up through the concrete floor and into the bottom of the drywall.
Floor leak. A leaking pipe under the floor (supply line, drain, or radiant heat) causes moisture to travel up the wall.
Shower/tub leak. A failed shower pan or tub seal causes water to leak behind the wall and soak the bottom drywall.
Flooding. Basement flooding or appliance overflow soaks the bottom of walls.
How to Fix Swollen Drywall Near Baseboard
Step 1: Fix the leak source. Identify and repair the water source. If the leak continues, the repair will fail.
Step 2: Remove the baseboard. The baseboard needs to be removed to access and assess the full extent of the damage.
Step 3: Cut out damaged drywall. Swollen, soft drywall must be cut out. Cut a clean rectangular section that extends into sound drywall.
Step 4: Let the area dry. Allow the wall cavity to dry completely. Use fans and dehumidifiers if needed.
Step 5: Install replacement drywall. Cut a new piece of drywall to fit. For basement or high-moisture areas, use moisture-resistant drywall.
Step 6: Finish and paint. Tape the seams, apply joint compound, sand, prime, and paint.
Step 7: Replace the baseboard. Reinstall the baseboard or install a new one.
