If you’re noticing cracks in your brick patios or facades, you may wonder if this is a cause for concern. While some small cracks may be harmless, others can signal a serious underlying issue that necessitates repair or replacement. Today we’ll talk about which brick cracks are normal, why they develop, and when you should call a bricklayer for help.
Why You Shouldn’t Ignore Brick Cracks
Most brick cracks are not considered to be normal. They can be the manifestation of an underlying foundation problem that needs immediate attention. If neglected, your home’s structural integrity may be threatened; on top of that, cracks bring down the curb appeal and value of the home. At the first sign of trouble, contact a trusted brick repair specialist in Michigan to address the issue promptly.
Reasons Why Brick Walls Crack
There could be many reasons behind the cracking of your brick walls:
1. Differential foundation settlement
Cracks can form when the foundation has settled into the ground unevenly. Differential settlement puts stress on your foundation, resulting in severe structural damage if not addressed. Differential settlement can happen due to a variety of causes, such as:
- Expansive soil
- Improper grading
- Erosion-prone soil
- Damage from nearby tree roots
When the foundation moves, the bricks on top of it will crack.
2. Hydrostatic pressure
Excess moisture in the soil sometimes can’t properly drain out, leading to the buildup of hydrostatic pressure. This pressure then pushes against the foundation, and if not relieved with proper drainage, your brick walls may start to bow inward and display horizontal cracks.
3. Thermal expansion
Because bricks are porous, they will expand when absorbing moisture and contract when releasing moisture. This motion may lead to vertical cracks. While not necessarily bad news structurally, you should have them inspected by a professional.
Causes For Concern
So when should you be worried about the cracks in your bricks? Be extra cautious when you see:
- Cracks that are wider at the top than the bottom
- Horizontal cracks (with or without bowing)
- Stair step-shaped cracks
- Cracks that are wider than 1/8 inch
If you notice any of the above, get the bricks checked out to prevent more significant damage and expensive repairs.
That being said, some cracks are harmless and aren’t a cause for concern. Hairline cracks in the brick or mortar, for example, are quite common and are a result of either seasonal weather changes or normal building settling. While not concerning at this stage, it’s important to keep an eye on them to ensure they don’t get bigger with time.
I See Brick Cracks: Now What?
If you see concerning brick cracks, you may wonder what the next step is. Cracks are usually the result of a foundation problem, so be on the lookout for other signs of foundation issues, such as:
- Cracks in floors and ceilings
- Ceilings and floors that do not come in contact with the wall
- Torn or wrinkled wallpaper
- Doors and windows that don’t properly open and close
- Chimneys or porches that lean away from the house
