High Humidity Causes Drywall to Absorb Moisture
When humidity stays above 60%, your drywall can begin absorbing moisture from the air.
Common Signs
•Soft or spongy drywall texture
•Slight warping
•Visible seams or joint swelling
•Paint that looks “wavy” or uneven
How to Prevent It
•Maintain indoor humidity between 40–55% using dehumidifiers or your HVAC system.
•Use exhaust fans during showers, cooking, or laundry.
•Keep interior paint well-maintained — quality paint helps block surface-level moisture.
Patch Perfect Recommendation
If you catch it early, we can typically dry out the affected area, stabilize the surface, and refinish it. If the drywall has softened or warped, replacing that section creates a longer-lasting fix.
Roof Leaks and Attic Moisture Create Ceiling Damage
Heavy Louisiana rainstorms can push water through weak roof points or flashing. That moisture often shows up in ceilings first.
Common Signs
•Water rings or discoloration
•Sagging drywall
•Bubbling paint
•Cracks expanding after storms
How to Prevent It
•Get roofs inspected annually, especially before hurricane season.
•Make sure attic insulation isn’t blocking ventilation.
•Address any ceiling stains immediately — stains usually indicate active or previous moisture.
Patch Perfect Recommendation
We remove damaged ceiling sections, ensure the area is fully dry, and reinstall new drywall with proper sealing and finishing. Whenever possible, we also help identify where the moisture originated so the issue doesn’t return.
Wall Cavities Trap Moisture After Heavy Rain
Exterior walls can collect moisture from wind-driven rain or small gaps around windows, doors, and siding.
Common Signs
•Staining below windows
•Musty smell inside walls
•Separation at baseboards
•Peeling interior paint near exterior walls
How to Prevent It
•Reseal windows and doors every few years.
•Repair any siding cracks or gaps quickly.
•Keep landscaping away from exterior walls to reduce splashback during storms.
Patch Perfect Recommendation
We cut out the affected drywall, ensure the cavity is fully dried, then rebuild the wall so it blends seamlessly. We use moisture-resistant materials when appropriate to help reduce future risk.

Moisture is one of the biggest threats to drywall in Louisiana — but most damage can be contained or prevented when you act fast.
