Foundations & Structure
Structural Modifications
Removing load-bearing walls, cutting new openings and installing beams – designed and sealed by a licensed engineer, built and supervised to that design.
Overview
Opening a kitchen to the living room, widening a doorway to a lanai, or cutting a new window into a block wall all change how a building carries its loads. When a wall supports a roof, a floor or a wind load, removing it means the load has to be picked up by a new beam, carried to new posts, and delivered to a foundation that can hold it.
Structural modifications start with a licensed structural engineer, who evaluates the existing structure and designs the beam, posts, connections and any new footings. We coordinate that evaluation, obtain the permit with the sealed drawings, and then manage the work: temporary shoring, removal, rerouting of utilities in the wall, installation of the new structure and the inspections that confirm it.
Who it’s for
- Homeowners who want an open floor plan and have walls that may be load-bearing
- Renovations adding wider openings to lanais, patios or additions
- Block homes that need a new window or door opening cut into an exterior wall
- Commercial spaces removing walls or columns to reconfigure a tenant area
- Projects adding loads, such as a heavier roof covering or rooftop equipment, that need existing structure reinforced
What’s included
Typically included
- Coordination of a structural engineer’s site evaluation of the existing framing, masonry and foundation
- Coordination of sealed drawings for the new beam, posts, lintels, connections and footings
- Permit coordination with the local building department
- Identification and rerouting of electrical, plumbing and HVAC in the affected wall by licensed trade partners
- Temporary shoring of floors and roofs before any bearing element is removed
- Careful removal of the wall or cutting of the opening, with dust and debris control in occupied homes
- New footings or thickened slab sections where the design requires them
- Installation of the beam – wood, engineered lumber or steel – with posts and connectors per the design
- Scheduling inspections and the engineer’s observation where the design calls for it
- Patching of adjacent ceilings, walls and floors to receive finishes
Common exclusions
- Engineering fees, when contracted directly by the owner
- Full finish work beyond patching, such as new flooring throughout or repainting entire rooms
- Correcting pre-existing structural deficiencies found during the evaluation, priced once defined
- Asbestos or lead testing and abatement, if older materials require it
- HOA or condo association approval fees
Every proposal lists its own inclusions and exclusions in writing.
Materials, design options & upgrades
How pricing works
Structural modifications are priced per project. The estimate is built from the engineer’s sealed design – beam size and material, posts, connections and any footings – plus shoring, demolition, utility rerouting, installation and patching.
Before the engineer evaluates the structure we can give a preliminary range, but the price is set once the design is complete, because what the wall carries and what the new structure must be are not known until then.
What changes the cost
- Span and load, which set beam size and material
- Flush versus dropped beam
- Utilities in the wall that must be rerouted
- Whether new footings are required below posts
- Shoring requirements and access in an occupied home
- Masonry cutting and lintel work for block walls
- Extent of patching and finish matching
If this work is part of a larger project, it’s priced within that project’s budget — please don’t add separate estimates together. Read the pricing guide.
Typical stages
Engineering evaluation
A structural engineer evaluates the wall, the loads above and the foundation below.
Design and permit
The engineer produces sealed drawings and we obtain the permit.
Prepare and shore
We protect the home, reroute utilities with licensed trades, and install temporary shoring.
Remove and build
The wall is removed or the opening cut, footings are placed if needed, and the beam and posts are installed.
Inspect
The building department inspects the new structure before it is covered.
Patch and close
Shoring comes out, and ceilings, walls and floors are patched for finishes.
What affects the schedule
- Engineering evaluation and drawing preparation come before permitting
- Building department plan review sets when work can start
- Steel beams or engineered lumber may need to be ordered
- Inspections must pass before the structure is closed in
Questions & answers
How do I know if a wall is load-bearing?
Clues include walls running perpendicular to joists or trusses, walls near the middle of the house, and walls directly above beams. But only a structural engineer evaluating the actual structure can confirm it and design the replacement.
Can the beam be hidden in the ceiling?
Often, with a flush beam, but it depends on the span, the load, the roof or floor framing and what runs through the ceiling. The engineer and framing conditions determine whether it is practical.
Can I stay in the house during the work?
Many owners do, with the work area sealed off for dust. Utilities may be interrupted briefly while they are rerouted. We plan the sequence with you before work starts.
Do I need a permit to remove a wall?
Structural changes typically require a permit with engineered drawings. Condo and HOA properties may also need association approval.
