The Importance and Process of Right-Sizing a Beam When Removing a Load-Bearing Wall

If you're planning to remove a wall to open up space in your home, it's critical to know whether that wall is load-bearing—and if it is, how to properly support what it holds up. One of the most important parts of this process is right-sizing the replacement beam.

In homes throughout Lexington, KY, especially older properties, structural walls are common and play a key role in keeping the house stable. Removing them requires more than a sledgehammer and ambition. It requires the right materials, calculations, and professional support.

Why Beam Sizing Matters

A load-bearing wall helps support the weight of everything above it—floors, roofing systems, and sometimes additional walls. Taking one out without proper support can lead to significant structural problems like sagging ceilings, cracked walls, or even major shifting of your home’s framework.

To avoid these issues, a properly sized beam must be installed in place of the wall. Beam sizing refers to choosing a beam that can safely carry the transferred load. Undersized beams may bend or fail over time, putting your home and safety at risk.

What Factors Go Into Beam Sizing?

Beam sizing isn’t one-size-fits-all. Several factors must be taken into account:

• The length the beam needs to span
• The type of load it needs to support
• The material of the beam (wood, LVL, steel)
• The type and placement of supports beneath it
• The local building code requirements in Lexington

Every home is different. A structural engineer will need to assess your specific situation to determine what’s required.

The Process of Removing a Load-Bearing Wall

Here’s a simplified look at how professionals approach this project:

1. Evaluation – A contractor or engineer first confirms whether the wall is load-bearing. They may check attic framing, floor plans, or make exploratory cuts.
2. Structural Design – An engineer calculates the correct beam size and support points. In Lexington, this step often includes reviewing Kentucky building codes to ensure compliance.
3. Permitting – The city may require permits and engineering plans. This protects homeowners from improper installations and liability.
4. Installation – Temporary supports are installed, the wall is removed, and the new beam is secured in place with appropriate posts and footings.

Removing a load-bearing wall can transform your home’s layout—but it’s not a DIY job. Getting the right beam size is critical to the safety and long-term stability of your home.
