Crawl space main beam replacement is a method of reinforcing or replacing the primary support beam in your home’s crawlspace to provide maximum support, strength, and durability. The crawl space is the area located directly beneath your home, and the main beam, also known as the girder, is a crucial structural component that carries the weight of your house.


Over time, these beams can deteriorate from wear and tear or rot, causing them to weaken. In severe cases, a compromised main beam can lead to significant problems, including sagging floors and cracked walls. Hence, beam replacement becomes necessary.

Structural beam replacement involves carefully removing the old, damaged main girder, preparing the crawlspace, and installing a new, high-quality beam. This requires expertise, specialized knowledge, and skills to ensure the new girder is correctly aligned and positioned to effectively bear the house’s weight and provide the necessary support.

LUX Crawl Space Main Beam Replacement Process

The crawl space primary beam replacement process is a significant undertaking that requires professional expertise. At LUX, our process for structural beam replacement in your crawlspace is thorough and effective, using advanced engineering techniques. Our experienced team is fully equipped to perform this task, ensuring the job is done correctly and safeguarding your home from potential damage.

Our installation process includes the following:

1. Inspection and Assessment

Our team begins by comprehensively inspecting the crawlspace, assessing the extent of the damage, the type of beam required for replacement, and the best strategy for removal and installation. This step is necessary to avoid any unexpected issues during the replacement process.

2. Planning, Bracing, and Support Layout

Based on our findings, we will develop a personalized plan of effective placement for the beam for your home. This plan includes selecting the right materials, determining the necessary equipment, strategies to place additional supports to redistribute the weight, creating a supported layout for the work, and scheduling the replacement procedure to minimize disruption to your daily routine.

3. Installation of Temporary Bracing

Next, following the plan, temporary bracing is installed to bear the weight of the house before removing the damaged beam.

These temporary bracings, made of lumber or jacks with a temporary beam, are critical to ensure the stability of the structure as we carry out the replacement process. This procedure requires precision and expertise to ensure the home’s structural integrity remains uncompromised.

4. Removal of the Damaged Main Beam

Once the temporary supports are securely in place, the damaged main beam will be carefully removed or detached from the floor joist. 


This process is handled with utmost precaution and precision to avoid any additional damage to the crawl space floor or the rest of the structure. It’s vital to ensure that all sections of the compromised beam are properly disposed of to prevent any potential safety hazards.

5. Installation of New Main Beam

Installing the new main beam is the next step in the process. Here, the new girder is measured, cut to fit, and then installed in the crawlspace. Our experts ensure the new beam is correctly positioned and aligned, guaranteeing its optimal function and longevity to ensure that it can effectively support the weight of your house.

6. Removal of Temporary bracing, Load Transfer, and Final Inspection

Finally, we make final adjustments to ensure everything is secure and tightly aligned before transferring the weight and loading everything properly. 

Then, the temporary bracing is carefully removed once the new beam is securely installed. A thorough final inspection follows this step to ensure the new girder appropriately supports the structure. The area is cleaned, leaving a safe and secure crawl space.

What causes wooden floor beams to rot?

Wooden floor beams can rot due to prolonged moisture exposure, creating an environment conducive to fungal growth. Common causes of moisture infiltration include leaks from plumbing, poor ventilation, or water seepage from the ground or foundation walls. When wood is consistently damp, fungi like mold and mildew thrive, leading to decay and eventual rot. 

Inadequate ventilation in crawl spaces can also worsen the issue by trapping moisture. Additionally, direct contact with water, such as flooding or plumbing leaks, accelerates the deterioration of wooden floor girders. Regular inspections for water damage, promptly addressing leaks, and ensuring proper ventilation are crucial in preventing the conditions contributing to wood rot and preserving the integrity of your floor girders.

How long does it typically take to replace a crawl space main beam?

The duration to replace a crawl space main beam can vary depending on factors such as the size of the structure, accessibility to the crawlspace, and the extent of the damage. On average, a crawlspace structural beam replacement may take a few days to a week. 


The process involves:

  • Careful planning.
  • Lifting and supporting the structure.
  • Removing the old girder.
  • Installing the new one with precision.

Factors like the need for additional repairs, such as addressing foundation issues or flooring adjustments, can also impact the overall timeline. It’s essential to consult with our professional team, who can assess the specific conditions of your crawl space and provide a more accurate estimate based on the project’s scope.

Can I continue living in my house while the crawl space main beam is replaced?

The feasibility of continuing to live in your house while the crawlspace structural beam replacement is done depends on the extent of the work and the specific conditions of your home. In some cases, temporary support structures may be implemented to ensure the safety of the dwelling during the replacement process, allowing you to remain in your home.


However, if the extent of the work poses safety risks or significant disruptions, it may be advisable to relocate during the construction period temporarily. Factors such as noise, dust, and potential interruptions to utilities could impact your daily life.


Consult with LUX to assess the project, clarify the specific circumstances, and help determine the most suitable arrangement for your living situation during the replacement.

Are there preventive measures to avoid the need for crawl space main beam replacement in the future?

Firstly, continued structural stress on the compromised area may result in further damage, causing sagging floors, uneven surfaces, or even structural failure. This deterioration can escalate repair costs and extend the duration of the replacement process. Additionally, neglecting timely replacement may exacerbate issues such as mold growth and insect infestations, negatively impacting indoor air quality and posing health risks. Further delays can also lead to complications in other parts of the home’s foundation and structural systems, requiring more extensive and expensive repairs. 


To mitigate these consequences, it is crucial to promptly address a damaged crawlspace girder, ensuring your home’s stability and long-term well-being.
