The key often lies in distinguishing between a "crack on the wall" and a "crack in the wall."
Understanding cracks in your walls can be tricky, as not all cracks mean big trouble.
Make it stand out.
"Crack On The Wall" vs. "Crack In The Wall"
A "crack on the wall" usually refers to a cosmetic issue, like a crack in the paint or plaster. These are often hairline and can be due to typical house settling or changes in temperature. Think of it as a surface-level imperfection. For example, a tiny crack in the paint on an interior wall is typically just that – a cosmetic fix, easily repaired with spackling and repainting. Generally, these aren't a major concern.
On the other hand, a "crack in the wall" suggests something more serious, potentially indicating structural damage. These cracks are often wider (more than 1/4 inch), grow over time, or appear with other troubling signs.
Here's a more detailed look:
When to Be Concerned
You should be concerned about a crack if it's:
Larger: Wider than 1/4 inch.
Growing: Continues to expand or change shape.
Diagonal: Especially if located above doors or windows, which can signal structural movement.
Accompanied by other issues: Look for signs like sticking doors or windows, or walls that appear to be bowing.
In these cases, it's always best to have a professional, such as a structural engineer or foundation repair specialist, investigate.
When Not to Worry
You might not need to worry about:
Small, hairline cracks: These are quite common and often result from normal settling or minor temperature fluctuations.
Single, isolated cracks: If they're not growing or part of a larger pattern, a single hairline crack often isn't a cause for alarm.
Cracks in new buildings: It's normal for new homes to settle, and some minor cracks might appear within the first few years.
