Cracked or Damaged Drywall – Causes, Fixes & Pro Tips

Drywall damage is one of the most common issues in both older homes and newer constructions. While it might seem like just a cosmetic problem, ignoring cracks or holes can lead to bigger issues down the road. Let’s break down why it happens, how to fix it, and some tricks to make the repair process smoother.

Why Does Drywall Crack or Get Damaged?

Drywall damage can happen for a number of reasons:

• Structural Shifting or Seasonal Movement: Changes in temperature and humidity can cause your home’s structure to expand or contract, leading to cracks.

• Everyday Wear & Tear: Accidental bumps from furniture, vacuum cleaners, or doorknobs are all too common.

• Improper Installation: If drywall wasn’t taped, mudded, or screwed in correctly, it may start to crack over time.

• Moisture Damage: Especially in basements or bathrooms, water damage can weaken drywall, leading to bubbling or crumbling surfaces.

Quick & Easy Fixes Based on Damage Type

Small Cracks:

• Use premixed joint compound (also called “mud”) and a putty knife to fill the crack.

• Let it dry completely.

• Sand it smooth using fine-grit sandpaper.

• Repaint the area to match the existing wall.

Small Holes (under 6 inches):

• Use a drywall patch kit (available at most hardware stores).

• Clean the area and place the patch over the hole.

• Apply joint compound over the patch and feather it out with a drywall knife.

• Once dry, sand it and apply a second coat if needed.

• Paint for a seamless finish.

Larger Holes or Water-Damaged Sections:

• For larger damage, you’ll need to cut out the damaged section, install new drywall, and tape/mud the seams.

• If moisture was the cause, address the source before repairing.

Pro Tips from the Pros

• Use a hairdryer or heat gun between compound layers to speed up the drying time (especially helpful in colder weather).

• Always feather the edges of the compound outward to blend with the wall.

• For a cleaner finish, use a sanding block instead of loose sandpaper.

• Use corner guards or door stoppers to prevent repeat damage.

Recommended Tools & Materials:

• Putty knife

• Joint compound (premixed)

• Sandpaper or sanding block

• Drywall patch kit

• Paint & matching primer

• Hairdryer (optional)
