Cracks in walls can be a homeowner’s nightmare, but understanding their causes is the first step in addressing the issue. At RSH Engineering and Construction, we’re committed to helping you maintain the integrity of your home. In this blog, we’ll delve into the various factors behind those pesky wall cracks, offer insights into wall crack repair, and provide expert guidance on how to prevent them in the first place. Let’s get started!
Common Causes of Cracks in Wall
One of the most common causes of cracks in walls is settlement. Settlement occurs when the ground beneath your home shifts and compacts over time. This natural process can result in small, vertical cracks in your walls. These cracks are often harmless and are usually found near the corners of doors and windows or along seams in drywall.
Moisture infiltration can wreak havoc on your walls. When water seeps into the foundation or walls, it can cause them to expand and contract, resulting in cracks. This can happen for various reasons, such as poor drainage around the foundation, leaky plumbing, or heavy rain.
To address moisture-related cracks, it’s crucial to identify and fix the source of the moisture. Repair any leaking pipes, improve your home’s drainage system, and ensure proper basement or crawl space sealing.
Extreme temperature changes can cause your walls to expand and contract, leading to cracks. This is particularly common in regions with harsh winters and hot summers. Concrete and masonry can contract when temperatures drop significantly, creating stress on the walls.
Consider using expansion joints or flexible sealants in areas prone to temperature fluctuations to minimize temperature-related cracks. Additionally, proper insulation can help maintain more stable indoor temperatures.
Inadequate construction practices can lead to cracked wall. This may include using low-quality materials, improper curing of concrete, or insufficient structural support. Over time, these issues can manifest as cracks in your walls.
If you suspect poor construction is the cause of your wall cracks, consult with a professional engineer to assess the extent of the problem and recommend appropriate repairs.
In some cases, cracks can be indicative of more serious structural problems. These issues may include foundation settlement, subsidence, or structural damage. If you notice large, persistent cracks or changes in the alignment of doors and windows, it’s essential to consult with structural engineers.
Structural engineers can thoroughly assess your home’s foundation and structural integrity. They can provide recommendations for drywall crack repair or other structural improvements to address the root cause of the cracks.
Types of Wall Cracks
Vertical cracks are often a result of settlement and are typically less concerning. They usually follow a straight path and can be hairline cracks or slightly wider. These cracks are generally straightforward to repair with suitable materials and techniques.
Horizontal cracks, on the other hand, can be a sign of more severe issues, such as foundation problems or excessive lateral pressure on the walls. These cracks are typically more comprehensive and may indicate that the wall is under significant stress. It’s crucial to have horizontal cracks evaluated by professionals promptly to determine the underlying cause and appropriate remediation.
Diagonal cracks can occur due to various factors, including soil pressure, settling, or differential movement between different structure parts. The angle and direction of oblique cracks can provide valuable insights into the underlying cause, helping engineers diagnose and address the issue effectively.
Spiderweb cracks are small, fine cracks often resulting from minor temperature fluctuations or settling. They typically radiate outward from a central point, resembling a spiderweb, hence the name. While these cracks are usually cosmetic and don’t pose a structural risk, they can be repaired for aesthetic reasons.
Wall Crack Repair
DIY Wall Crack Repair
For minor cracks, you can undertake simple repairs yourself. Clean the crack using a wire brush or chisel to remove loose debris. Next, fill the gap with an appropriate wall crack filler, such as epoxy or polyurethane. Follow the manufacturer’s instructions for mixing and applying the filler. Once the filler has dried, sand it smooth and paint over it to match the surrounding wall.
It’s essential to note that DIY repairs are suitable for small, non-structural cracks. If you have concerns about the severity of the crack or suspect underlying structural issues, it’s best to consult a professional.
Professional Wall Crack Repair
For significant cracks or when unsure about the cause, it’s crucial to consult professionals. Professional wall leaking repair involves a comprehensive assessment of the crack, its cause, and the best approach for repair. Depending on the situation, professionals may use techniques like epoxy injection, carbon fiber reinforcement, or other specialized methods to restore the wall’s integrity.
Professionals can also identify and address any underlying structural issues that may have contributed to the cracks. This comprehensive approach ensures a long-lasting solution that goes beyond cosmetic repairs.
Wall Crack Fillers
Various wall crack fillers, including epoxy and polyurethane options, are available on the market. These fillers effectively seal cracks, preventing moisture intrusion and further damage. When using wall crack fillers, choose a product compatible with your wall’s material and the severity of the crack. Proper surface preparation and application techniques are crucial for a successful repair.
Regular Home Inspection
Regular home inspections play a vital role in preventing vertical cracks in wall. Whether you’re a new homeowner or have been in your home for years, scheduling periodic pre-existing home inspections can help identify potential issues early. Trained inspectors can assess the condition of your walls, foundation, and overall structure, providing recommendations for maintenance and repairs as needed.
Foundation Inspection Company
In addition to general home inspections, consider hiring a specialized foundation inspection company. These experts evaluate the stability and integrity of your home’s foundation. A thorough foundation inspection can detect early signs of settlement, subsidence, or structural problems, allowing you to take preventive measures before cracks develop.
Proper drainage around your home’s foundation is crucial in preventing moisture-related cracks. Ensure that your gutters and downspouts are clean and functioning correctly. Redirect rainwater away from the foundation by using downspout extensions or grading the soil away from the house. Adequate drainage helps reduce the risk of water seeping into the walls and causing damage.
Maintain Consistent Humidity
Fluctuations in indoor humidity can contribute to cracks in wall, especially in dry climates. When indoor air becomes too dry, materials like drywall can shrink, leading to cracks. Conversely, excessive humidity can encourage mold growth and weaken structural elements.
Maintaining a consistent indoor humidity level through humidifiers or dehumidifiers can help minimize the expansion and contraction of materials, reducing the likelihood of cracks.
Understanding the causes of cracks in walls is essential for homeowners seeking to protect their investments. Whether you’re dealing with minor cosmetic cracks or suspect more significant structural problems, taking action promptly is crucial.
