When you spot a crack in your ceiling, you don’t need to panic—but you should investigate to see if it’s linked to a larger underlying problem. If you’re unsure, bring in a professional to check it out. But if you’re confident that the damage is merely cosmetic, you can learn how to repair ceiling cracks yourself with this step-by-step guide.
Prepare the Space
Start by moving any furniture and other belongings out of the room. Then, lay down drop cloths to protect the floors from old, flaking drywall, joint compound, and paint.
Next, set up your ladder so that it’s stable and allows you to reach the ceiling comfortably. Before using it, make sure you’re well-versed in ladder safety.
Clean Up the Crack
Put on your safety goggles and mask, then climb on the ladder so that you can reach the crack.
With a utility or drywall knife, scrape off any flaking paint, joint compound, or other loose material around the crack. Be sure to work with the crack (and not across it). Cut off any damaged drywall tape and secure any loose or uneven drywall with drywall screws.
Finally, get rid of any dust by wiping down the area with a clean, damp cloth. Wait for it to dry completely before moving to the next step.
Tape the Crack
Cover the length of the crack with a single long strip of drywall tape. Make sure the crack is in the middle of the tape. This will help strengthen the repair, bond the compound, and prevent sagging.
Patch the Crack

Otherwise, if you have powdered compound, mix it with water according to the manufacturer’s directions. When it’s ready, put it into a mud pan.
Use a putty knife to scoop the compound out of the mud pan. Apply it over the drywall tape, moving in one direction. Try to get the layer as thin as possible (or it might crack later on). Use a bucket of water and a damp cloth to clean any leftover compound from the knife as you go.
Let the compound dry fully, and then repeat the process at least two more times for a total of three (or more) layers. When you’re done, the compound should completely hide the crack.
After applying the last layer, let it dry for at least 24 hours.
Smooth It Out
When the compound is completely dry, it should turn white. At that point, you can sand it smooth with a drywall sanding block.
When you’re done, use a clean, damp cloth to remove all dust from the area.
Prime and Paint

If you have paint to match the color of the ceiling, repaint the cracked section. If not, you might want to paint the whole ceiling for a fresher, more consistent feel.
DIY vs. Hiring a Pro
Fixing a minor ceiling crack isn’t terribly complicated, but it does involve climbing on a ladder and working above your head. If that’s not your thing or you have physical limitations, hire a drywall repair expert instead of tackling this project yourself.
Angi Tip
Getting up on a ladder to work on your ceiling is dangerous. Unless you have experience and a buddy nearby to help you, call a pro to complete the job.
When you hire a ceiling repair pro near you, the average cost to repair ceiling cracks is $400 to $1,350. Meanwhile, DIY repairs are more affordable, costing up to $150.
For a small cosmetic crack, you could save money by hiring a local handyperson instead of a drywall repair company. But if you have large or widespread ceiling cracking, you should consult a general contractor. They’ll be able to determine if the cracks are related to structural issues or water damage.
Frequently Asked Questions
There are several warning signs that a ceiling crack is connected to a larger issue. For starters, if the crack is wider than 1/8 inch or longer than 12 inches, you might have a more serious problem. The same applies if you have multiple smaller cracks or cracks going across the ceiling and down the wall. In any of these situations, you should ask a professional to assess the damage.
On average, repairing a ceiling costs anywhere from $450 to $1,750. However, there are many variables that can impact the price of this project. For example, the type of ceiling material, type and extent of the damage, and local labor rates all affect your costs. Holes and cracks are less expensive to fix, while structural issues and water damage are pricier problems.
