Knocking down a wall can open up space and completely change how a home feels. But if that wall is load-bearing, the job requires precision and structural support otherwise, you risk weakening your home’s entire frame. The safe way forward is to replace the wall with a properly sized support beam. Here’s how pros handle it, and what a prepared homeowner should know.
1. Plan and Consult
Hire a structural engineer or licensed contractor to determine if the wall is load-bearing.
Obtain permits before starting; inspectors will require calculations for the beam size.
Decide on the type of beam (LVL, steel I-beam, or doubled/tripled lumber) based on the load.
2. Prepare the Work Area
Turn off electricity to the wall and reroute wiring, outlets, or switches.
Remove drywall carefully to expose studs, checking for plumbing or HVAC runs.
Clear the room and cover floors with protective sheeting.
3. Build Temporary Supports
Construct temporary support walls on both sides of the load-bearing wall, about 3 feet away.
Use 2x4 studs spaced 16 inches apart, running from floor to ceiling.
These walls carry the weight while the main wall is removed.
4. Remove the Load-Bearing Wall
Cut out wall studs one by one after removing the top plate.
Dispose of debris safely while leaving space for the new beam.
5. Install the Beam
Measure and cut the support beam to fit the span.
Lift the beam into place (often requires multiple people or temporary jacks).
Rest the beam on sturdy posts at both ends, these transfer the load down to the foundation.
Secure with metal brackets, bolts, or engineered connectors as specified by the engineer.
6. Finish the Job
Remove temporary support walls only after the beam is fully secured.
Patch drywall, reroute electrical, and finish surfaces around the new beam.
Schedule an inspection to ensure the beam installation meets code.
Conclusion
Removing a load-bearing wall isn’t a casual DIY, it’s structural surgery for your house. With proper engineering, temporary supports, and a strong beam in place, you can open up your living space safely without sacrificing stability. The result is a modern, open layout built on solid ground.
