Can Stair Step Cracks Be Fixed?
Like diagonal cracks, stair-step cracks occur due to the differential settling of the foundation. If they're only found in the mortar joints between the brick or block, the crack is not serious and can be repaired by simply reapplying the mortar. Brick buildings provide the impression of solid structures. With so many landowners embracing the “exposed brick” appearance for their homes, some issues are unavoidable.
Cracked bricks are a typical problem with brick walls. While cracked brickwork may not usually signify major structural problems, it can make your property susceptible to water damage and mold.
What Are the Causes of Stair Step Crack in Brick?
1. Soil Subsidence
It all starts with the building of the house. Soil excavation has taken place in order to lay the foundations of a building. The ground settles over time, and the foundation of the home slides somewhat. This movement can generate minor vertical cracks, which are usually not an issue.
Depending on the type of soil on which your house is built, your house may endure more drastic movement, which can cause significant damage. Natural calamities such as earthquakes, floods, and hurricanes can severely destroy your home’s foundation.
2. Climate and Seasonal Changes
The materials used to construct our homes respond quite a bit to climatic and seasonal fluctuations. Long periods of drought, as well as rain and water, can cause damage to the walls and foundations.
3. Building Materials Corrode and Deteriorate
Building materials do not last indefinitely. Weather, gravity, and poor upkeep all have an ongoing impact on our structures. Building reinforcement is prone to corrosion, especially if the concrete base is not adequately installed. Foundation fissures expose the steel reinforcement to moisture, which can cause rusting and lead to brick wall cracks.
4. Construction Works in Your Area
If you live near a building site, your brick walls may be affected. Heavy machinery, excavation, and digging may cause your brick walls to break.
5. Regions Where Soils are Highly Reactive
Soils like clay expand when wet and split and shrink when dry. You may notice minor cracks in your walls if your home is built on clay soil.
Unfortunately, these cracks are usually cosmetic in nature and can be easily repaired. Cracks larger than 3 mm should be taken seriously, and an expert should be called to evaluate your home or building.
6. House Surrounded by Trees
Having large trees close to your home might cause brick walls to crumble. As a result, their root systems are invasive and can damage your home’s foundation. In addition, they require a lot of water, which can alter soil moisture.
Also, cracks in walls can be caused by dry soils. Small brick cracks are typical and do not signal an issue with the foundation. This is due to the fact that brick has a natural tendency to expand.
Large brick cracks on your house’s facade (or in your concrete slab foundation) may signal that you need foundation repair. It’s not a good sign if the fractures in your brick are bigger at the top than they are at the bottom. It’s possible that you’ll need foundation repair. This is because fissures like this typically indicate that your home’s foundation is shifting.
Do Cracks in Brick Mean Foundation Problems?
Bricks are composed of inflexible baked clay that has been crushed. As a result, when your house settles or due to external forces, they’re more likely to crack. Small cracks in brick walls are widespread and usually innocuous. Large brick cracks on the outside of your house, on the other hand, may signal a foundation problem.
A cracked brick should be replaced as soon as you notice it. Your home could be damaged by water entering via a fracture in the masonry, which could cause structural damage and interior finishes to be damaged. If there is excess moisture, mould might develop, which can be costly.
In most home improvement stores, you can purchase affordable bricks for this project. But don’t just ignore it! It’s possible that your foundation has further problems if the break extends beyond a single brick. Especially if there are multiple cracks in brick, it’s possible that there is an underlying cause.
How Much Does It Cost to Repair a Brick Foundation?
Minor foundation cracks might cost as little as $500, while major foundation repairs can cost as much as $10,000. The sooner you get cracks repaired, the less money you’ll have to spend. For a one-story home with modest cracks, exterior brick wall cracks can be repaired for $450 to $600.
The Average Foundation Repair Cost The majority of foundation repairs cost between $4,000 and $10,000 to complete. Over time, all houses settle, but if yours settles too much, it can cause serious structural issues. Piering and underpinning problems are repaired for $1,340 to $1,500 per pier.
Homeowners pay an average of $10/sq.ft. to repoint brick. In some cases, costs might reach up to $25 per square foot, depending on the materials and labor employed.
