Introduction

Seeing cracks in your basement walls can be pretty scary. If you ignore them, they might get worse and could make your house weak and less valuable. It’s important to fix these cracks quickly. In this blog, we will talk about why these cracks happen, how to check if they are serious, and how you can fix and prevent them.

Understanding Basement Wall Cracks

Types of Cracks

• Horizontal Cracks: These are the most serious. They usually mean the soil outside is pushing too much on your walls.
• Vertical Cracks: These are common and usually not too serious. They often happen because the house is settling.
• Diagonal Cracks: These happen due to uneven settling or soil pressure.
• Hairline Cracks: These tiny cracks might not be a big deal right away, but it’s good to keep an eye on them.

Common Causes of Basement Wall Cracks

• Soil Pressure: Soil that expands and contracts can push on your basement walls and cause cracks.
• Water Damage: Constant moisture can weaken the walls and create cracks.
• Foundation Settlement: As the ground settles, it can cause cracks in your walls.
• Climate Changes: Big temperature changes can make the walls expand and contract, leading to cracks.

Checking the Severity of the Crack

Visual Inspection Tips

• Size: Measure the crack. Bigger cracks are usually more serious.
• Direction: Horizontal cracks can be more worrying than vertical ones.

Tools for Measurement

• Crack Monitors: These help you see if the crack is getting bigger over time.

When to Call a Professional

• Structural Engineers: Call them if the cracks look bad or if you’re not sure how serious they are.
• Professional Contractors: They can give you an expert opinion and fix the cracks if needed.
