Removing a Load-Bearing Wall: Beam Sizing, Steel vs LVL

Steel or LVL: how do you size the replacement beam?

For investors and property owners working on Camillus rental conversions and flip projects, the load-bearing beam decision is one of the highest-leverage technical choices on the job. Pick the right beam and the wall comes down clean, the inspection passes, and the open footprint sells. Pick wrong and you eat the cost of pulling the framing back open to swap the member. The load-bearing wall removal decision math reduces to span, load, headroom, and finish constraint.

When LVL Wins

LVL (laminated veneer lumber) beams are the right call for most CNY residential wall removals under 18 feet of clear span. They are cheaper, lighter, easier to install, and the finished ceiling depth is forgiving. A 14-foot span carrying a single story of load typically takes a triple 1.75 by 11.875 LVL with point loads transferred to bearing columns at each end. Total material cost runs 600 to 1100 dollars.

When Steel Wins

Steel (W-shape or built-up plate beams) takes over when the span exceeds 18 feet, when the headroom constraint requires a shallower beam depth than LVL can provide for the load, or when point loads from two stories above transfer down through the wall. A typical 22-foot residential span with a second floor above runs a W8 by 31 or W10 by 22 depending on tributary load. Material is 1800 to 3200 dollars but the install requires crane access or sectional fab.

The investor mistake we see most often is over-specifying steel where LVL would have done the job for a third of the cost. The other direction happens too: families try to value-engineer their way into LVL for a 22-foot span and end up with bouncing floors above. Match the member to the span, do not match it to the budget.

– Elijah Mercer Boone, Lead Project Manager

Headroom and Finish Detail

Steel wins on headroom every time. A W10 beam buried in the floor system above takes 10 inches of depth. An equivalent LVL takes 16 to 18 inches. For Camillus capes and ranches with low ceilings already, the steel often pays for itself in not requiring a dropped soffit. Whenever the project also calls for a cathedral ceiling ridge beam vault, the steel-vs-LVL conversation has to happen at both the wall removal and the ceiling vault simultaneously.

Engineering Sign-Off Is Not Optional

Any wall removal requires stamped engineering drawings for the Onondaga County permit. The structural engineer fee runs 800 to 2200 dollars depending on complexity. Skipping the engineer is how investor projects end up unable to refinance or close at sale, especially when the wall removal is part of a broader kitchen renovation or home additions scope.

Closed-Cell Spray Foam Below Grade: Why It Matters

If you are finishing a Marcellus basement and the contractor wants to use fiberglass batts against the foundation wall, stop the project. Fiberglass batt insulation below grade is one of the most predictable failure modes in CNY basement construction. Within five years the foundation cools the batt, condensation forms, the batt holds the moisture, and mold and rot follow. Closed cell spray foam basement insulation is the only foundation-wall insulation strategy that survives our climate without these failures.

Second-Story Addition Costs in Central New York

Your Westvale cape was built in 1948 with two upstairs bedrooms tucked under the roofline, and your growing family has outgrown it. You have a yard you love and neighbors you do not want to leave. The math question on the table is simple: does it make sense to add a second story instead of selling and moving up? In Central New York the answer comes down to honest numbers, not the optimistic figure you saw in a TV remodel show.

Finishing a Basement with Active Moisture: Where to Start

If your Cicero basement has active moisture problems and you want to finish the space, the worst possible thing you can do is start with cosmetic work. Drywall over a damp wall and the wall starts growing mold within months. The right protocol to finish basement with moisture is the opposite of intuition: stop, diagnose the source, fix it, verify it is fixed, then build. Skipping any of those steps is how Cicero basements turn from refresh projects into remediation disasters.

Detached ADU Utilities: Trenching and Subpanel Routing

In Auburn's Historic District the lots are deep and the zoning often supports a detached unit, which makes the structure the easy part. The hard part is buried in the yard. Running power, water, and sewer from the main house to a detached accessory dwelling unit is a trenching and routing problem with frost, code, and old utilities all in play. Plan the detached ADU utilities before you pour the foundation, because retrofitting a service run after the slab is down is the expensive way to learn this lesson.

LVL handles most standard openings; steel earns its cost on long spans past 20 feet or heavy point loads.
A licensed structural engineer, and Onondaga County wants that stamped calc with the permit.
Often yes; a flush beam sits in the joist depth, while a dropped beam is cheaper but visible.
