5 Common Causes of Cracks in Drywall and How to Prevent Them
When you notice cracks forming on your walls, it can be both frustrating and concerning. Whether they’re hairline fractures or deeper splits, drywall cracks often signal an underlying issue that needs attention. Understanding what causes these cracks can help homeowners prevent costly repairs down the road.
At
Wendell Barco Plastering, we specialize in
drywall repair in Portsmouth, VA, and we know that no two cracks are alike. Some stem from natural house settling, while others can be a sign of structural movement or improper installation. In this post, we’ll explore the
five most common causes of drywall cracks and share professional tips to prevent them from returning.
1. Structural Movement and House Settling
One of the most common causes of drywall cracks is natural structural movement. Over time, every home settles slightly as the soil beneath the foundation shifts due to temperature changes, moisture, and gravity. This gradual movement places stress on your walls, leading to cracks—especially near doors, windows, and corners.
While minor settling is normal, larger or widening cracks could indicate a more serious foundation issue. If you see cracks forming in the same spot repeatedly, it’s best to call professionals who can assess the problem.
Prevention Tip:
To minimize structural movement, make sure your home’s foundation drainage is functioning properly. Keep gutters clean, direct downspouts away from the house, and maintain consistent indoor humidity levels. Regular inspections by a drywall expert can also help detect early signs of structural strain before they worsen.
2. Poor Drywall Installation
Improper drywall installation is another leading cause of cracks. If drywall sheets aren’t properly secured, or if joints aren’t taped and finished correctly, even slight stress can cause seams to separate over time. Cracks that appear straight and follow drywall joints often result from poor workmanship.
This issue can occur when fasteners are spaced incorrectly, joint compound is applied unevenly, or insufficient drying time is allowed between coats.
Prevention Tip:
Always hire a professional contractor experienced in drywall repair and installation. Skilled technicians, like the team at Wendell Barco Plastering, ensure the right materials and techniques are used from the start—preventing cracks before they appear. Properly finished seams and joints not only look better but also provide lasting durability.
3. Temperature and Humidity Changes
Virginia’s coastal climate can take a toll on drywall. Fluctuations in temperature and humidity cause materials to expand and contract, putting pressure on joints and seams. Over time, this repeated stress leads to cracking—especially in older homes or rooms without climate control, like attics and basements.
Even interior heating and cooling systems can contribute to this problem if the humidity isn’t balanced.
Prevention Tip:
Keep indoor humidity levels between 30% and 50%. Use dehumidifiers in damp areas and maintain steady indoor temperatures year-round. Sealing cracks early with professional
drywall repair in Portsmouth, VA, helps prevent moisture from worsening the issue. Additionally, using high-quality joint compounds and flexible caulk can accommodate minor movement caused by climate change.
4. Foundation or Structural Issues
Cracks that are wide, diagonal, or appear suddenly may indicate foundation problems or significant structural shifts. When a foundation settles unevenly or sinks, it exerts pressure on the drywall, leading to cracks not only on walls but also along ceilings and door frames.
Ignoring these cracks can lead to more serious problems down the line, including uneven floors and wall misalignment.
Prevention Tip:
If you notice recurring or expanding cracks, it’s essential to have a professional inspection. A drywall expert can determine whether the issue stems from the foundation or surface-level damage. Fixing minor cracks early with drywall repair can save you from more extensive repairs later, but foundation work may be required for severe cases.
5. Water Damage and Moisture Intrusion
Moisture is one of drywall’s biggest enemies. Water from roof leaks, plumbing issues, or high humidity can weaken drywall, causing it to swell, stain, and eventually crack. You may notice bubbling paint, soft spots, or mold growth in addition to visible cracks.
Bathrooms, kitchens, and basements are particularly vulnerable areas due to frequent exposure to moisture.
Prevention Tip:
Regularly inspect your home for signs of leaks or water damage. Seal gaps around windows, pipes, and vents. Use moisture-resistant drywall in areas prone to humidity. If you suspect water infiltration, have it repaired immediately before scheduling professional
drywall repair in Portsmouth, VA to restore your walls and prevent mold growth.
The Importance of Professional Drywall Repair
While small cracks may seem like a minor cosmetic issue, they can signal deeper structural or moisture problems. Attempting to patch them yourself may offer a temporary fix, but without addressing the underlying cause, they’ll likely return.

FAQs
What causes drywall cracks to reappear after repair?
Cracks often return when the underlying cause—such as foundation movement or humidity changes—is not properly addressed. Professional repairs ensure that both the surface and source of the problem are fixed.
How do I know if a drywall crack is serious?
Hairline cracks are usually cosmetic, but larger, diagonal, or widening cracks can indicate structural movement or foundation issues. Have a professional inspect them for safety and repair recommendations.
Can I paint over drywall cracks?
Painting over cracks without repairing them first only hides the problem temporarily. The cracks will eventually reappear. It’s best to patch and refinish the area before applying a new coat of paint.
How long does drywall repair take?
Minor repairs may take just a few hours, while larger sections or water-damaged walls may require a couple of days to complete. Drying and finishing time also depend on humidity and temperature.
How often should I inspect my drywall for cracks?
It’s a good idea to inspect your walls at least twice a year, especially after seasonal changes or home renovations. Early detection can prevent more extensive and expensive damage later.
