Supporting Beam Installation After Wall Removal: What Homeowners Should Know

Removing a load-bearing wall is only half the job—installing the right supporting beam is essential for your home’s safety. Here’s what every homeowner should know about the process, costs, and safety tips for beam installation after wall removal.

Why Is a Supporting Beam Needed?

When you remove a load-bearing wall, a new supporting beam must take on the structural load the wall used to carry. The wrong beam size or installation method can lead to sagging, cracks, or even collapse.

For safe engineering and installation, see our structural engineering services.

What Types of Beams Are Used?

  • Steel Beams (I-beams):Strongest option; ideal for long spans, heavy loads, and modern renovations.

  • LVL Beams (Laminated Veneer Lumber):Engineered wood; strong and cost-effective for most homes.

  • Wood Beams:Used in some older homes, but less common for major structural support today.

How Is a Supporting Beam Installed?

1. Engineering Assessment

A structural engineer determines the required beam size and support points.

2. Temporary Support

Before the wall is removed, temporary shoring walls are built to hold up your house during the work.

3. Beam Placement

The new beam is lifted into place—often requiring special equipment or a professional team.

4. End Supports or Posts

The ends of the beam rest on new or existing columns, which transfer the load to the foundation.

5. Inspection and Approval

City inspectors review the work before drywall and finishing can be completed.

Costs of Supporting Beam Installation

Typical beam installation (including engineering, materials, and labour) ranges from $3,000 to $10,000+ depending on size, type, and complexity.

  • Steel beams are usually more expensive than LVL.

  • Longer spans and heavier loads increase costs.

Safety Tips for Homeowners

  • Never guess the beam size!Always use professional engineering calculations.

  • Insist on permits and inspections.

  • Use experienced, licensed contractors for installation.

  • Don’t rush the process—structural safety comes first.

Frequently Asked Questions

Can I install a beam myself?Not recommended! Improper installation risks your home’s structure and safety.

Will the beam be visible?Beams can often be hidden inside the ceiling, or left exposed for a modern look.

How long does installation take?Typically 1–2 days, not including finishing.
