Foundation cracks are often the first sign of a structural issue in your home and come in a variety of forms.
Horizontal cracking and stair-step cracking for masonry basements, and corner cracking in poured concrete foundations, are tell-tale signs your foundation needs a thorough inspection. Fixing the cause of the foundation crack is the first step, then reinforcing the foundation against future cracks and finally repairing the damage from the foundation crack comes next.
How to tell if a foundation crack needs repair:
- The foundation crack is letting moisture or odors into the basement.
- The crack in the basement wall or floor is more than a surface, hairline crack from concrete curing. If the crack is approaching 1/8 inch in width, the problem has become more serious.
- The crack in your foundation is growing over time.
If you see any of these signs in your foundation cracks, it is time to get an inspection. Foundation cracks don't get better over time, only getting worse and leading to more expensive repairs.
Repairing foundation cracks is the work of trained foundation experts, requiring a full inspection to assess and repair properly.

Frequently Asked Questions
Vertical wall cracks in a poured foundation wall often aren't as serious as horizontal ones. Hairline vertical cracks are not uncommon as concrete walls cure. Simply sealing these cracks and protecting from future damages should be enough. If the cracks grow over time and our wider at the top than the bottom, more serious issues might be at play, including a sinking or sagging foundation creating vertical pressure on the wall and threatening your home's structural integrity. To be safe, you should always have foundation wall cracks inspected by a professional.
If there are vertical cracks in a block wall foundation they should always be looked at by a professional because block walls will not get shrinkage cracks. This could be a sign of a more serious foundation issue.
Horizontal cracks are a greater sign of bowed walls or structural foundation problems than their vertical counterparts. Hydrostatic pressure from expanding soil due to moisture changes can exert tremendous lateral pressure, causing horizontal cracks to form in basement walls. Left unattended, these horizontal cracks tend to grow with time creating more serious issues, potentially a full wall collapse.
Any cracks in the foundation not caused by concrete curing - normally surface, hairline cracks - are foundation cracks to worry about. Vertical and diagonal cracks in poured concrete walls near corners are usually caused by lateral pressure, while a sinking foundation can cause vertical or diagonal cracks anywhere. Both are foundation cracks to worry about. Horizontal cracks and stair-step cracks in masonry foundations are two other types of cracks to be most worried about. Also, any crack that is larger than 1/8" or that is letting water into your basement is a foundation crack to worry about.
If there's water coming through a foundation crack, the first thing to do is to make sure it's draining properly into a floor drain and that the water is cleaned up quickly. Water in your basement can lead to odor and mold problems. Next, check for any drainage issues outside the house to make sure water is running away from your foundation. Finally, get a foundation expert to throughly inspect the cause of the water coming through your foundation crack to protect against it happening in the future and to repair any structural issues that have been caused.
When you have a crack in your foundation where it meets the basement floor, there are a number of options based on what type of crack it is. If the crack is a hairline, surface crack indicative of concrete curing, particularly in newer homes, it probably doesn't require immediate attention. If the crack is larger than 1/8 inch then it should be sealed with caulking to prevent basement leakage. If the crack appears to be caused by the basement floor heaving upward, that could indicate the start of more serious structural issues from soil expansion and requires a thorough inspection from an expert.
Common fixes for foundation cracks vary widely based on the unique circumstances of the building and its foundation. Smaller cracks not caused by deeper structural issues - such as wet clay, hydrostatic pressure or frost heaving - are commonly repaired with caulks or epoxies that seal the foundation crack. When soil expansion or settling is going to put continuous and growing pressure on the foundaction cracks, then more advanced fixes are common - wall anchors, wall braces or carbon fiber straps, for instance.
