Cracks in your plaster walls might seem like a small problem—until they’re not. Ignore them, and they can turn into costly repairs or even structural nightmares. So, when should you grab some filler and when should you call in the pros? Let’s break it down.
Small Cracks? DIY Can Do the Trick.
Hairline cracks? No big deal. These are usually just from natural settling or minor shifts. A bit of filler, some sanding, and a fresh coat of paint can get your walls looking brand new. But before you DIY, make sure the crack isn’t growing or reappearing—because that’s a warning sign.
Bigger Cracks? Time to Investigate.
If you’ve got cracks wider than 2mm, spreading quickly, or forming stair-step patterns, you might have a structural issue. No amount of patching will fix what’s happening underneath. This is where a professional assessment is key—because what you can’t see might be doing the real damage.
Signs You Need a Professional ASAP:
- Cracks keep coming back – If you’ve patched the same spot more than once, something’s moving behind the scenes.
- Doors and windows don’t shut properly – Could be a sign of foundation movement.
- Large, deep, or widening cracks – This could mean shifting foundations or serious wall damage.
- Bulging or sagging plaster – Moisture damage or structural problems need more than just a quick fix.
Get It Fixed Right—Before It Gets Worse.
Small cracks can be a weekend project, but if they’re showing signs of something bigger, don’t risk it. A professional can spot underlying issues, make proper repairs, and save you from bigger (more expensive) problems down the track.
