How much does load-bearing wall removal cost?

The engineer first determines what the wall supports and how the reaction reaches the foundation. The design may include a beam, header, posts, frame, bearing checks, connections, and foundation work, along with calculations and permit drawings when required. I tell homeowners to ask whether the proposal addresses the complete load path rather than only naming a beam size.

• Existing floor, roof, wall, and lateral loads above the opening
• Beam or frame design, deflection, bearing, connections, and restraint
• Posts, footings, slab or crawlspace support, and concentrated reactions
• Field verification, calculations, drawings, details, seal, and AHJ responses if included

The contractor turns the accepted design into construction pricing. That proposal can include demolition, protection of finishes, material procurement, labor, disposal, temporary shoring means and methods, posts or footings, inspections, patching, and coordination with plumbing or electrical trades. Shoring design or engineering observation should be named separately when the project requires it; it should not be silently assumed.

• Demolition, dust and finish protection, hauling, and disposal
• Temporary support, sequencing, access, safety, and means-and-methods planning
• Beam, posts, connectors, footing work, installation labor, and equipment
• Framing repair, drywall, flooring, paint, utilities, inspections, and closeout

An engineering fee is not a contractor quote, and a contractor's allowance is not a structural design. Compare them only after the project team has defined the opening, permanent support, assumptions, temporary-work boundaries, finish expectations, and permit path. I recommend asking the engineer and contractor to identify conflicts before demolition, because a change in span or support can change both proposals.

• Match the contractor's scope to the current signed structural documents
• Confirm who owns shoring design, site observation, and inspection coordination
• Separate structural, architectural, MEP, fire, and finish work
• Hold contingency for concealed conditions without disguising it as a guaranteed price
