Common Causes of Ceiling Cracking and What to Do about Them

repairing cracked ceiling

Are you seeing cracks in your Gyprock ceiling? At times, the crack is just a cosmetic issue that is an eyesore but not anything you should be particularly worried about. However, it may also indicate that something is genuinely wrong, and you should take action immediately to fix it. 

Here are some of the typical reasons for ceiling cracks and what you can do to ensure your effort to fix the ceiling addresses the underlying source of the issue.

Paint Peeling Off the Surface

The paint on the ceiling may be peeling for several reasons, as you may have seen. High humidity, inadequate surface preparation before painting, applying too many coats of paint, or employing a paint type incompatible with the surface are all possible causes.

You can apply the appropriate paint to cover the area and scrape off the loose paint when this occurs. Always give each coat ample time to dry completely before adding the following ones. It’s a good idea to attempt to lower the room’s humidity levels to avoid this happening again.

Fine, Spiderweb-Like Cracks

If you notice spiderweb-like cracks on the ceilings, it may result from joint compound splitting or older layers of paint that have aged and cracked. A thick coating of joint compound tends to shrink after application, leading to the emergence of small fissures.

You might use a thin coating of drywall compound to hide these flaws. They’re typically just superficial flaws and don’t need immediate intervention.

Cracks with Staining or Discoloration

There may occasionally be a brown or yellow stain in the ceiling cracks. This can signify an above-water leak that seeps through to the ceiling. The joint tape may become loose as a result, developing fissures. Unattractive discolouration may result from dampness or water.

You must first repair these ceiling fractures before fixing the water leak. To determine the source of the current problem, you might speak with a plumber. They will examine the roof for any damage that would allow rainfall to enter the roof and check the water pipes for leaks.

Remedial treatment on the water-damaged ceiling may only be carried out once the root cause has been appropriately identified and treated. This usually calls for replacing a part of the joint tape with a new segment of tape fastened using two or more coatings of joint compound. 

Certain plasterboard portions might also need to be replaced if the water leak significantly damages them. You might want to hire a reliable plastering service for a task like this.

Cracks Where the Ceiling Meets the Wall

Truss uplift may cause any fractures you notice around the points where the ceiling and the wall meet. The roof trusses tend to vary due to the changing seasons and humidity, which causes them to move or shift a bit. Even though this is a prevalent problem, most houses are built to withstand changes in roof truss height.

Although it is often not a structural issue, a cosmetic fix will not prevent the trusses from being the cause of the fractures. It could be necessary to make some alterations, such as reattaching the plasterboards to the trusses.


As you can see, cracks in your ceilings are usually a result of a wide variety of different causes. This can make fixing them a confusing and frustrating task for homeowners.

If the cracks on your ceiling result from any of the problems mentioned, you should take the necessary action immediately. Do you need help with your Gyprock ceiling in Brisbane? We Plaster & Recruit provides the best fully licensed and insured plastering services. Request a quote today!
