There are few things more frustrating than seeing cracks appear on freshly painted walls. Whether they’re hairline fractures or deep splits, drywall cracks can ruin the appearance of your home and indicate deeper structural issues. Luckily, with the right approach, you can eliminate them forever and enjoy perfectly smooth walls.
This guide explains why cracks form in drywall, how to properly repair them, and what steps you can take to prevent them from recurring.
Why do cracks occur in drywall?
Cracks in drywall are common, but understanding the cause is the key to a lasting repair. Here are the most common reasons behind them:
Settling down
Over time, all homes settle a bit, causing stress on drywall seams and causing cracks – especially near doors, windows or ceilings.
Bad installation
If the drywall was poorly taped or the joint compound was applied unevenly, cracks may appear within a few months. Proper installation is important for durability.
Fluctuations in temperature and humidity
Drywall expands and contracts due to changes in humidity. Due to repeated movements, the joints become weak and lines or splits start appearing.
Foundation issues
Large cracks may indicate foundation movement or water damage, which requires professional inspection.
Water leakage or moisture damage
Hidden leaks can soften drywall and cause it to crack, bubble, or peel over time.
Types of Drywall Cracks and What They Mean
Hairline cracks: Usually cosmetic; Appear along seams or corners.
Diagonal cracks: May indicate foundation movement or stress points.
Cracks in ceiling: Can result from poor taping or attic temperature changes.
Corner cracks: Common in high traffic areas due to vibration or impact.
Knowing the type of crack helps determine the correct repair method.
How to Repair Drywall Cracks Effectively
Step 1: Clean and prepare the area
Use a utility knife to widen the crack slightly, removing loose debris or flaky material. Clean the area thoroughly before applying the compound.
Step 2: Apply Joint Compound
Use a putty knife to apply a thin layer of joint compound over the drywall cracks. Apply paper or mesh tape to the wet compound for reinforcement.
Step 3: Smooth and Sand
After the first coat has dried, apply two more thin coats, letting each dry completely. Lightly sand the surface between coats for a smooth finish.
Step 4: Prime and Paint
Once the repaired area is dry and level, apply primer before repainting. This ensures uniform color and texture on your wall.
Preventing future drywall cracks
It’s one thing to repair cracks and another to prevent them from recurring. Here’s how to make your walls sustainable:
Maintain consistent humidity: Use a dehumidifier or humidifier to prevent expansion and contraction.
Address structural problems quickly: Fix any foundation or framing issues before they get worse.
Use high-quality materials: Choose strong joint tape and flexible, premium-grade compounds.
Control Room Temperature: Avoid excessive heating or cooling changes in your home.
Hire professionals for major repairs: Expert drywall services ensure the job is done right the first time.
With these steps, your walls will remain solid and crack-free for years.
