What To Do If You Spot Cracks After An RSJ Installation
Installing a Rolled Steel Joist (RSJ) is a critical part of many home renovation projects, especially when removing load-bearing walls or creating new openings. While RSJs are designed to provide essential structural support, it’s not uncommon for homeowners to notice cracks after installation. Understanding the causes and knowing how to address these issues is crucial for maintaining the safety and integrity of your home.
If you’re reading this before you’ve started your RSJ installation journey and are wondering whether it’s better to tackle this yourself or with a professional team - read our blog: DIY or Professional RSJ Installations.
Here’s what you should do if you spot cracks after a DIY RSJ installation.
Assess the Severity of the Cracks
The first step is to assess the severity of the cracks. Minor hairline cracks are often normal and may result from the natural settling of the structure. However, larger or widening cracks can be a cause for concern. Measure the cracks and monitor if they’re growing over time. If you notice significant changes, it’s important to act promptly.
Consult a Structural Engineer
If you observe any worrying signs, consult a structural engineer as soon as possible. A professional can accurately diagnose the issue and determine whether the cracks are a result of improper RSJ installation or other underlying problems. Structural engineers have the expertise to assess the safety of your home and recommend necessary repairs or reinforcements.
Check for Installation Issues
Improper RSJ installation can lead to structural issues and cracking. Common installation problems include inadequate support, improper alignment, or insufficient load-bearing capacity. Ensure that the RSJ was installed according to the manufacturer’s specifications and building codes. If you suspect any installation errors, a professional should inspect and rectify them.
Wondering how much weight an RSJ can support?
If you have used a professional RSJ Installation company such as Wall Away then you needn’t be worried about structural issues - if you decided to install an RSJ yourself then it’s worth consulting our team to see how we’ll be able to ensure the correct implementation of a future RSJ.
Here’s What To Do If Your RSJ Installation Goes Wrong
Address Moisture and Environmental Factors
Sometimes, cracks can result from environmental factors such as moisture or temperature fluctuations. Ensure that the area around the RSJ is properly sealed and protected from moisture. Excessive dampness can weaken building materials and exacerbate cracking. Address any water ingress or ventilation issues promptly to prevent further damage.
Monitor and Document Changes
Keep a detailed record of the cracks, including their size and any changes over time. Regularly monitor the situation and take photographs to document any developments. This information will be valuable for professionals assessing the problem and can also be useful for insurance claims if necessary.
Seek Professional Repair Services
Depending on the assessment by your structural engineer, you may need to engage professional repair services. Qualified contractors can provide the necessary repairs or reinforcements to address any issues identified. It’s essential to use experienced professionals to ensure that the repairs are done correctly and that the structural integrity of your home is maintained.
Prevent Future Issues
Once the immediate issues are addressed, take steps to prevent future problems. Ensure that all structural work is carried out by qualified professionals and that regular inspections are conducted. Proper maintenance and timely repairs can help avoid more significant issues down the line.
So, What Should You Do If You Spot Cracks After An RSJ Installation?
Noticing cracks after an RSJ installation can be concerning, but with prompt and informed action, you can address the issue effectively. Always consult with a structural engineer to diagnose the problem and ensure that your home remains safe and structurally sound. By taking these steps, you’ll protect your investment and enjoy peace of mind knowing that your home is in good hands.

FAQs
How can I differentiate between normal settling cracks and those that indicate a structural problem after an RSJ installation?
To differentiate between settling cracks and structural problems, focus on the size and location of the cracks. Settling cracks are typically hairline and appear near joints or at the ends of the load path. Structural cracks are often wider than 0.25 inches, run diagonally, and may appear suddenly. If you observe any widening or lengthening of cracks, or if they are accompanied by other signs of structural distress such as sagging floors or doors that won't close, it's crucial to consult a structural engineer.
What specific steps should I take to properly seal and protect the area around the RSJ to prevent moisture-related issues?
To properly seal and protect the area around an RSJ, ensure that all joints and connections are fully sealed with appropriate sealants to prevent moisture ingress. Use waterproof or water-resistant materials close to the RSJ, especially in areas prone to dampness. Additionally, improve ventilation around the RSJ to help manage humidity and condensation, which can contribute to moisture problems.
Can changes in temperature really affect an RSJ and cause cracking, and if so, how?
Yes, changes in temperature can affect an RSJ and lead to cracking in the surrounding materials. Metal expands when heated and contracts when cooled, and these movements can place stress on the mortar and other construction materials that are not as flexible. Over time, this stress can cause cracks to develop, particularly if the RSJ wasn't properly installed with sufficient allowance for thermal expansion and contraction.
What are the risks of not addressing cracks related to RSJ installation immediately?
Failing to address cracks related to RSJ installation promptly can lead to serious structural issues. These include the potential collapse of the supported structure, further propagation of cracks leading to extensive damage, and increased repair costs over time. Neglecting these signs can also significantly reduce the safety of the building, posing risks to its occupants. Immediate action can help mitigate these risks and preserve the structural integrity and value of your home.
