The Dangers of Wall Cracks
The only way to truly determine whether a wall crack is dangerous or not is to have it checked by a professional; that said, you can look at cracks yourself to see whether you need to call someone or not. During the first year or two after construction, it’s perfectly normal to notice small, thin cracks here and there. This is because during that time, houses settle. However, if you see a gaping or horizontal crack in your wall this may indicate damage and need to be checked out.
The first step to determining the seriousness of a wall crack is to examine it to see which direction it is going on the wall. If the crack is vertical and starts near the corner where the wall and ceiling meet, it might be a sign that it was created when the foundation settled after construction. Vertical cracks run the same direction as drywall, generally making them less serious.
If the crack is horizontal or runs at a jagged 45-degree angle, it might mean there’s a more serious problem such as severe foundation shifting or water damage. These wall cracks usually require professional attention to address and fix, and depending on their severity may require some reconstruction.
A stair-step crack looks like a flight of stairs and runs in both vertical and horizontal directions across the wall. These wall cracks are typically found on the cinder block walls of unfinished basements. Mostly, they are just caused by soil settling after construction. Unfortunately the only definitive way to tell if the issue is serious is to hire an engineer to perform soil tests and core drill tests to determine what repairs are needed.
Doors and Windows
Another way to test the seriousness of a wall crack is to open and close internal doors to bedrooms and bathrooms and evaluate whether the doors stick. If so, ensure the sticking isn’t a result of paint, damaged hardware or cracked wood. If you find that there’s nothing obstructing the swinging motion of the door, it could be a sign of a moderate to severe foundation change, which frequently causes wall cracks.
If you look at the area surrounding the wall crack and see nail or screw heads sticking out, this is known as “nail popping” or “nail pops”. This is when the nail or screw pulls away from the wooden stud that’s underneath the drywall. They probably didn’t damage the drywall, but nail popping can be an indicator of structural issues and should be addressed.
