How to Fix Ceiling Cracks in WA’s Great Southern Region

Cracked ceilings can be a worry, especially if you’re unsure about the cause or how to repair them. In WA’s Great Southern region, cracks in ceilings can result from several common factors, including structural issues, water damage, or changes in humidity.

In this guide, we’ll walk you through how to assess ceiling cracks and the best ways to repair them – plus when it’s best to call a professional.

Why Do Ceiling Cracks Appear?

Ceiling cracks are not uncommon, and understanding what causes them can help you make an informed repair choice. Here are some of the main reasons ceilings crack:

• Structural Shifts
  Homes naturally shift over time due to settling or minor movements in the foundation. These changes can cause cracks, especially in older houses.
• Water Damage
  Leaks from roofs, plumbing, or air conditioning units can weaken the ceiling material, leading to cracks or sagging.
• Humidity Changes
  Humid weather can cause building materials to expand and contract. In WA, seasonal changes in humidity can lead to ceiling cracks.
• Poor Construction Quality
  If the original construction wasn’t up to standard or used poor materials, cracks can appear as the ceiling ages.

Identifying the cause of a crack can help determine whether you need a simple fix or professional support.

How to Assess the Severity of Ceiling Cracks

Not all cracks are the same. Some are minor cosmetic issues, while others signal more serious structural problems.

Here’s how to tell the difference:

• Thin, Straight Cracks
  Small, narrow cracks are often superficial and not a cause for alarm. They can usually be patched easily.
• Wider Cracks (Over 3mm)
  Cracks wider than 3mm (about 1/8 inch) could indicate structural issues. It’s a good idea to have these inspected by a professional.
• Sagging Ceilings
  If the ceiling looks sagging or drooping, this is a sign of potential water damage or structural concerns. In this case, you should contact a professional immediately.

DIY Ceiling Repair for Minor Cracks

If your ceiling has small, cosmetic cracks, a DIY repair might be all you need. Here’s a simple step-by-step guide for handling minor cracks yourself:

1. Prepare the Area
   Move any furniture below the crack and cover it with a drop sheet to protect it from dust and debris.
2. Clean the Crack
   Use a utility knife to carefully remove any loose material around the crack. This will help the filler adhere better.
3. Apply Joint Compound
   With a putty knife, spread the joint compound or plaster into the crack, feathering it out so it blends with the surrounding ceiling.
4. Sand Smooth
   Once the compound is fully dry, gently sand the area until smooth.
5. Prime and Paint
   Apply a coat of primer, then paint to match the rest of the ceiling.

A DIY approach can be perfect for small, cosmetic cracks. However, if you find cracks reappearing, it may be a sign of a larger issue.
