Every open-concept kitchen starts with the same conversation: "that wall is coming down." Then someone asks what the wall is holding up, and the price of the answer turns out to be most of the budget. A non-load-bearing partition comes out for the cost of a dumpster and a weekend. A load-bearing wall is a structure problem wearing drywall, and the money goes into replacing what it was doing — carrying the floor or roof above it — with a beam, posts, and footings that do the same job invisibly.
Before pricing anything, confirm the wall actually is load-bearing. Our guide to what a load-bearing wall is covers the checks — direction of the joists above, what's stacked over it, where it sits in the house. If it isn't carrying anything, this whole article gets much cheaper. If it is, here's where the money goes.
These are hedged ranges, not quotes — every engineer's report reshapes the numbers. But they reflect how the jobs usually stack up.
| Scenario | What the job involves | Typical total range |
|---|---|---|
| Single story, short span (under ~12 ft) | LVL beam, often recessed flush into the ceiling; posts land on existing footings or a slab | Roughly $4,000–$8,000 |
| Single story, longer span (12–20 ft) | Bigger LVL or glulam, more shoring, more finish work at both ends | Roughly $7,000–$15,000 |
| Two-story home | Posts must carry the load down through the first floor to new footings in the basement or slab | Roughly $12,000–$25,000+ |
| Long span or steel beam | Steel I-beam or flitch plate, sometimes a crane or extra crew to set it, engineered footings | Roughly $15,000–$30,000+ |
The engineer. A structural engineer inspects, calculates the load, and specs the beam, posts, and footings. Expect a few hundred dollars for the visit and report, in some markets around $1,000. This is not a place to economize — the contractor builds to this spec, and the inspector checks against it.
The permit. Structural work needs one, almost everywhere, no exceptions worth taking. Permit fees usually run a few hundred dollars and buy you inspections that protect you at resale. Unpermitted structural work has a habit of surfacing during a buyer's inspection years later, when it's your problem at the worst possible time.
The beam itself. Material is rarely the budget-killer, but the type matters. An LVL (laminated veneer lumber) handles most residential spans and often costs a few hundred dollars. Glulam runs more. Steel costs more again, plus the crew or equipment to wrestle it into a ceiling. Deeper beams that can't hide in the joist space become a visible soffit — sometimes the real cost driver is the deeper section a flush install demands.
The load path down. A beam moves the load to its two ends, where posts concentrate it into point loads the original structure was never built for. In a two-story home or over a basement, that often means new concrete footings — digging, forming, and pouring inside your house. This line item surprises people more than the beam does.
Whatever lives inside the wall. Wires, plumbing vents and drains, HVAC ducts — walls are where houses hide their utilities. Each one gets rerouted by a licensed trade, and a single duct trunk or drain stack can add more than the beam cost. Opening the wall during the engineer's or contractor's walkthrough, before the quote, is the only reliable way to know.
Finishes. The structural work ends with a hole in your house. Patching the ceiling, marrying two floor surfaces where the wall stood (hardwood is the expensive version of this problem), texture, paint, trim, and disposal typically add a few thousand more, and homeowners forget them in every first estimate.
Engineer's assessment and stamped plans. The engineer confirms what's being carried, sizes the beam and posts, and specifies the footings. Everything downstream prices off this document.
Permit application. Filed with the engineer's plans. Timelines vary by city from days to weeks — another reason the permit isn't the step to skip or rush.
Temporary shoring. Before anything comes down, the crew builds temporary support walls on both sides to carry the load while the real wall is out.
Demolition and rerouting. The wall comes down, utilities get moved by their trades, and electrical and plumbing inspections happen while everything is open.
Beam, posts, and footings. The new structure goes in, gets inspected, and only then does the shoring come out.
Finishes. Drywall, floors, trim, paint. The slow, visible part — and the part you'll actually look at for the next decade.
Collecting quotes before the engineer. Without a beam spec, three contractors quote three different jobs, and the cheapest number is cheapest because it quietly assumes the least structure. Our checklist on what to settle before you hire a contractor applies double here — get the spec first, then let everyone bid the same work.
Budgeting only for the structure. The beam is half the story. Floors, ceilings, paint, and rerouted utilities routinely match it. Estimate the whole project or expect a mid-job surprise.
Assuming the framing is standard. Older homes hide surprises — doubled-up joists, previous unpermitted alterations, masonry that shares the load. How your house is actually framed changes the engineering, which is why wood framing vs. masonry construction matters more to this budget than the price of lumber does.
Skipping the permit to save a few hundred. The savings are fictional. You lose the inspection, the paper trail for resale, and possibly your insurer's cooperation if anything ever goes wrong near that opening.
Budget roughly $4,000–$15,000 for a typical single-story opening, more for two stories, long spans, or steel — and treat the engineer and permit as the first money spent, not the first money cut. Get the wall verified, get the beam spec'd, open the wall before final quotes, and budget the finishes from day one. Done in that order, this is one of the most predictable big projects in a house. Done in any other order, it's a story people tell at parties.
Typically a few hundred dollars for the assessment and beam specification, reaching around $1,000 in pricier markets or for complex two-story loads. It feels steep for a report — until you realize every contractor quote, the permit, and the inspection all run off that document.
Yes. Structural alterations require a permit in effectively every jurisdiction, along with inspections at the framing stage. The permit also creates the paper trail that protects you when you sell — unpermitted beam work is a classic deal-killer when a buyer's inspector finds it.
You can safely handle the non-structural ends of the job — demolition after shoring is engineered, and the finishes afterward. The middle (temporary supports, beam sizing and setting, footings, load path) belongs to pros working from an engineer's spec. That's where the cost concentrates, and also where the risk does.
The structural phase typically runs a few days to a week once permits are in hand. Finishes stretch the total to two or three weeks in many projects, and the permit itself can take days to weeks depending on the city. Anyone promising a two-day start-to-finish job is skipping steps.
An LVL is engineered wood — cheaper, lighter, easy for a framing crew to set, and enough for most residential spans. Steel carries more load in a shallower profile, which matters on long spans or when headroom is tight, but it costs more in material, handling, and sometimes engineering. Your engineer's calculations, not preference, make the call.
