3 Things You Need to Know About Vertical Cracks

Vertical foundation cracks can appear on newly constructed homes (1-2 years old) or older homes (2-20+ years) and can be a steppingstone towards serious issues down the road. Similarly to horizontal or stair stepping cracks found in the home, the foundation repair industry encounter these cracks daily and, in this post, we will provide for you 3 examples of vertical foundation cracks and what your best course of action is.

Example #1: Hairline Vertical Foundation Cracks

Figure 1: Hairline Vertical Foundation Crack: Can typically be considered as more of an aesthetic issue than a structural issue.

We are including this on our list because this is how every vertical crack first appears. A hairline vertical foundation crack, from an expert’s opinion, can be solely an aesthetic issue. Typically, a vertical crack of this size is simply due to aging of the home or moderate settlement that every home, old or new, experiences in its lifetime. As a house ages, some of the materials used for various components of the home can dry out and shrink. Continuous changes in temperatures, changes in humidity levels, and changes in the moisture levels of the soils that the structure rests upon can also cause movement within the various components of the house and can result in cracking.

Although these hairline cracks can solely be an aesthetic issue, it is important to monitor these cracks, to ensure that they do not separate or widen, as they can occasionally be the early signs of a more significant issue.

As the homeowner, take precautions to ensure that your home goes unaffected by the presence of these cracks and take the necessary steps to protect your investment and prevent future issues. Ensure that all water properly drains away from your home and that all penetrations (including hairline cracks) are properly sealed. Water is essential, but it is also one of the biggest threats to a home. The grade around the home should be sloped in a manner that properly diverts water away. If and when a drainage system is required, the system should be routinely inspected to verify it is properly functioning. Gutters and gutter downspouts should be kept clean and downspouts should be piped or extended to keep water away from the foundation of your home.

We are including this on our list because it shows what a hairline vertical foundation crack can potentially progress into if underlying issues exist and if the necessary steps are not taken. A crack of this size is typically a sign of a structural issue, such as foundation settlement, and is commonly caused by differential settlement within the structure and movement within the soils beneath the home. This settlement and movement does not only show itself through vertical cracks. There are several other signs and indicators that point towards something being wrong, such as

  1. Gaps & SeparationGaps and separation within various components can be found present, such as gaps around windows and door openings, separation in wood trim and molding, and separation between walls, ceilings, and floors.
  2. Exterior WallsWalls, particularly basement walls, may begin to bulge, bow, or shift out of alignment.
  3. Cracks around window and door openings Cracks within the brick, concrete, stone, block, and drywall of both the exterior and interior sides of the outside walls can often be found around the window and door openings.

As the homeowner, the best course of action in this situation is to call a trusted foundation repair company to diagnose the issue and bring applicable, and easy to understand solutions to the table. Lucky for you, Carolina Foundation Solutions is such a company. We present solutions that will remedy your issue after the conclusion of our FREE consultation/inspection of the property.

Figure 4: Vertical Foundation Crack Progression: Worst case scenario that is typically due to poor underlying soil conditions

We are including this on the list because this crack demonstrates how severe a vertical foundation crack can get if left untreated. The appearance of a crack this size is a sign of serious structural issues, and that the integrity of your foundation is compromised. Something of this magnitude puts you and anyone else in the home at risk. Cracks of this size are commonly a result of poor underlying soil conditions. The presence of poor underlying soil conditions can be a result of the following:

  1. Poor DrainageA lack of proper management of the drainage around a home can lead to saturation of the soils and even erosion of the soils that the structure rests upon. Many of the soils within our region can soften, experience a great deal of movement, or can become very unstable when saturated. The soils can also be broken down and washed away by the elements. This erosion diminishes the stability that soil offers and can ultimately be a contributing factor to foundation settlement and the development of vertical foundation cracks.
  2. Poor Native SoilsSome types of soils within our area are simply more susceptible to excessive movement as compared to other types of soils. Changes in moisture content and fluctuations within the water table can lead to expansion and contraction of the soils and can also weaken the soils.
  3. Inadequate Preparation / Poor ConstructionUnfortunately in some situations the poor soils can be a result of the proper steps not being taken during the initial construction of the home. This can consist of failure to properly test the existing soils, failure to properly compact the soils, and/or use of bad fill material.

Once a crack of this size is noticed the course of action you need to take is calling a trusted foundation repair company. Carolina Foundation Solutions specializes in providing permanent solutions, such as the installation of helical piers, to address your foundation settlement issues. Our team of certified installers will then come to your home and install the helical piers, consisting of hot dipped galvanized steel piles through the weak soil and down to a layer of strong stable soils. CFS will then fasten steel underpinning brackets to the base of the foundation, which will transfer the loads of the structure through the helical piles down to the layer of stable soils. These systems will then provide the necessary support and prevent your home from any future movement/settlement.

The key takeaway here is to be proactive instead of reactive when you notice a vertical foundation crack. The issue can only get worse over time resulting in more complicated and costly repairs. A strong foundation means a strong and safe home. CFS is a top-rated foundation repair company in the Carolinas that specializes in providing support for you and your family’s home when you need it most.
