Cracks in plaster walls are more than just cosmetic – they can signal deeper structural problems, moisture damage, or poor installation. At Romeo’s Plaster Repairs Canberra, we specialise in repairing cracked plaster walls for homes, offices, and commercial properties across Canberra and the surrounding suburbs. Whether it’s a small surface crack or a long vertical fracture along your living room wall, our experienced team is here to restore your surfaces to a smooth, clean finish.

With over 10 years of hands-on experience, we understand the common causes of plaster cracks in Canberra homes – from soil movement and ageing materials to temperature fluctuations and poor building techniques. We don’t just cover up the problem; we assess the underlying cause and fix it properly so it doesn’t return.

Why Plaster Walls Crack in Canberra

Plaster cracking is one of the most common issues we see in both new builds and older homes. Some of the most frequent causes include:

  • Foundation movement or settlement: Canberra’s clay-rich soils can expand and contract with seasonal weather changes, putting stress on walls and causing cracks.
  • Moisture damage: Leaks from plumbing, roofs, or rising damp can weaken plaster and lead to cracking.
  • Temperature fluctuations: Canberra’s hot summers and cold winters can cause plaster to expand and contract, creating tension that eventually leads to cracks.
  • Aging materials: Over time, older plaster becomes brittle and more prone to hairline fractures and crumbling.
  • Poor workmanship: Inadequate installation, incorrect jointing or lack of proper surface preparation can cause premature cracking.

Our Crack Repair Process

We take a detailed, professional approach to repairing plaster cracks—ensuring both aesthetic quality and long-term durability.

1. Inspection & Types of Cracks We Repair

Our team is experienced in identifying and repairing all types of plaster wall cracks, including:

  • Hairline cracks – Fine surface cracks caused by shrinkage or temperature changes
  • Vertical and diagonal cracks – Common near doors and windows, often due to foundation movement
  • Step cracks – Follow mortar lines and may indicate structural issues
  • Ceiling to wall joint cracks – Caused by roof framing movement or building expansion
  • Cracks from water damage – Usually appear with staining or mould
  • Crumbling plaster – Often the result of water damage or poor bonding

    Not sure what type of crack you have?
    Contact us for a free inspection. Early repairs can prevent serious damage later.

2. Diagnosis

We assess the area to determine the root cause of the cracking. If we detect any structural or moisture-related issues, we’ll advise you on the next steps.

3. Surface Preparation

We remove loose or damaged plaster, then clean and prime the area to ensure strong adhesion for the repair materials.

4. Crack Filling & Re-Plastering

Cracks are filled using premium-grade plaster compound or jointing material. For deeper cracks, we use mesh tape to reinforce the area before re-skimming to a smooth finish.

5. Sanding & Blending

Once dry, the surface is sanded and carefully blended with the surrounding wall or ceiling for a seamless result.

6. Optional Painting

If required, we can repaint the repaired area to match your existing décor, restoring the wall or ceiling to its original appearance.
