Common Causes of Wall Cracks After a Hurricane

 
Immediate Steps to Assess the Crack
 

• Examine the crack for size, length, and severity.
• Determine if the crack is superficial or if it appears to be structural. Small, hairline cracks are usually cosmetic, but larger or expanding cracks could indicate underlying issues.
• Check nearby areas such as ceilings, floors, or adjoining walls for additional signs of damage.
• If the crack appears to be growing or if you notice water stains or sagging, it could be a sign of a serious problem needing professional evaluation.

 
Tools and Materials Needed
 

• Putty knife or drywall knife
• Crack filler or joint compound
• Sandpaper (fine grit)
• Primer and paint that match your wall color
• Dust mask and safety goggles for protection
• Cleaning cloth and a bucket of water or mild detergent to clean the area
• Optional: Drywall mesh tape, especially for longer cracks

 
Step-by-Step Guide to Fixing the Crack
 

• Clean the Area: Use a cleaning cloth with water and mild detergent to remove any dust, grease, or loose debris from around the crack. Allow the wall to dry fully.
• Prepare the Crack: With a putty knife, gently widen the crack very slightly to allow the filler to better adhere to the wall. Remove any loose particles.
• Apply the Filler: Using the putty knife, apply the crack filler or joint compound into the crack. For wider cracks, you may first apply drywall mesh tape over the crack and then spread the compound over it.
• Smooth the Surface: Ensure the filler is pushed firmly into the crack and then smooth it out. Feather the edges so that it blends with the surrounding area.
• Let it Dry: Allow the compound to dry as per the manufacturer’s instructions. This may take several hours or overnight.
• Sand the Area: Once dry, sand the region lightly with fine-grit sandpaper until the surface is smooth and flush with the wall.
• Prime and Paint: Apply a coat of primer first to ensure proper adhesion of the paint. After the primer dries, repaint the area to match the rest of your wall.

 
DIY vs. Calling a Professional
 

• If the crack is small, superficial, and clearly cosmetic, many homeowners can handle the repair using the steps above.
• However, if the crack is wide, recurring, or accompanied by other issues like water damage or uneven flooring, it is better to call a professional.
• For cracks indicating structural problems, a licensed general contractor or a structural engineer should assess and repair the damage.

 
Who to Call
 

• General Contractor: For drywall repairs that might be symptomatic of broader issues, this professional can help diagnose and repair structural concerns.
• Structural Engineer: If there is any sign of structural failure, a structural engineer should be consulted to review the integrity of the building.
• Specialty Repair Services: Companies like St. Louis and Nashville offer full-service residential and commercial repairs that include handling drywall and structural issues.

 
Safety and Insurance Tips
 

• Always wear safety goggles and a dust mask when sanding or applying compounds to protect yourself from dust and debris.
• If you’re working on a ladder or in an elevated area, ensure it is stable and that you take proper fall-prevention measures.
• If you suspect the crack is due to structural issues, avoid working on it until a professional has evaluated the situation to prevent further damage or injury.
• Check your homeowner’s insurance policy to see if wall repairs may be covered, especially if the damage is due to an unforeseen event like water damage or a minor earthquake.
