Not All Cracks Are Serious.
Some cracks are cosmetic and occur naturally as concrete cures and ages. Others may indicate foundation settlement, soil movement, hydrostatic pressure, or structural stress.
The location, direction, width, and whether the crack is changing over time are some of the most important factors when determining whether a crack should be monitored or professionally evaluated.
What Type of Crack Are You Seeing?
Identifying the type of crack is the first step in understanding what it could mean and whether it needs professional attention.
Hairline Crack
Small, thin cracks often caused by normal concrete curing and shrinkage. Typically cosmetic unless the crack is widening.
Learn MoreStair-Step Crack
Often found in brick or block mortar joints and may indicate foundation movement or settlement. Should be monitored for changes.
Learn MoreHorizontal Crack
Can suggest pressure against a basement wall from soil or water. Horizontal cracks should generally be evaluated by a professional.
Learn MoreVertical Crack
Can range from cosmetic to structural depending on movement, location, water intrusion, and whether the crack is getting wider.
Learn MoreA Crack Is Only One Clue.
During an inspection, Jim looks at the whole picture — not just the crack itself. The surrounding signs often help determine whether the issue is cosmetic, moisture-related, settlement-related, or potentially structural.
Monitor It or Have It Evaluated?
Not every crack requires immediate action. However, certain signs may indicate movement, pressure, moisture intrusion, or structural concerns that deserve a closer look.
