Structural steel beam installation in Hamilton is priced by span, load, and ceiling access, not by a flat per-foot rate. A short, lightly loaded span with easy ceiling access prices toward the low end, while a long span carrying heavy point loads with limited access and extensive temporary shoring prices well above it. This guide walks through what the beam actually replaces, what drives the price up or down, what engineering and permit costs are included, how steel compares to LVL on cost, and how long a typical single-beam project takes.
If you already know a steel beam is the right call, our structural steel beam page covers scheduling and fixed pricing. If you are still comparing options, keep reading.
What a Structural Steel Beam Replaces When a Wall Comes Out
A structural steel beam replaces the load path that a load bearing wall was carrying before removal, transferring the weight of the floors or roof above down through posts to the foundation instead of through the wall itself. When that wall comes out to open up a floor plan, something has to pick up the exact same job the wall was doing, and a steel beam is one of two common choices, the other being engineered lumber (LVL).
Steel is typically chosen over LVL when the span is long, the load is heavy, or ceiling height is tight enough that steel's shallower profile for an equivalent load capacity matters. For a full breakdown of when steel makes more sense than LVL and vice versa, see our steel beam vs LVL beam guide, which covers the material comparison in more depth than this cost-focused post does. If you are not yet certain the wall in question is even load bearing, our guide to identifying a load bearing wall is the right starting point before pricing anything.
The beam is only part of the cost. Temporary shoring, new posts and footings, engineering, and the permit all add to the number, and all of them are specific to your home's layout rather than a standard package price.
What Drives Installation Cost: Span, Load, Access
Span is the single biggest driver. A longer span needs a deeper or heavier beam to carry the same load without excessive deflection, and beam weight scales with both span and load together, not span alone. Load works the same way: a beam under a roof-only load costs less than an identical span carrying two floors above it, since the engineer has to size the steel for the heavier total.
Access is the factor homeowners underestimate most. A beam installed in an open, unfinished basement with clear overhead space is straightforward to manoeuvre and lift into place. The same beam in a finished basement, or one with ductwork, plumbing, or electrical already running through the ceiling cavity where the beam needs to go, requires more disassembly, more labour, and sometimes a smaller beam section shipped in multiple pieces and welded or bolted together on site, all of which adds cost.
Engineering, Permits, and Inspection Costs Included
Structural engineering for a single-beam installation typically runs several hundred to just over a thousand dollars depending on complexity, covering the load calculation, beam sizing, and stamped drawings the City of Hamilton permit application requires. The permit fee itself is a smaller line item, scaled to project scope, and together these typically add a meaningful percentage to the total project cost rather than a negligible add-on.
A framing inspection is required before the ceiling closes up around the new beam, confirming the installed beam, posts, and connections match the approved engineered drawings. BaseWorks includes engineering, the permit, and inspection scheduling directly in the fixed-price quote, so the number you are given up front is the number that covers the whole process, not just the steel and labour.
Steel Beam vs LVL Beam Cost Comparison at a Glance
Steel generally costs more per linear foot of material than LVL, but that is not the whole cost picture. The table below breaks down where each option tends to add or save money across a typical project.
| Factor | Steel Beam | LVL Beam |
|---|---|---|
| Material cost per linear foot | Higher | Lower |
| Profile depth for equivalent load | Shallower | Deeper |
| Max practical span | Longer | Shorter, before stacking is needed |
| Ceiling modification needed | Less likely | More likely on long or heavily loaded spans |
| Installation labour | Often requires lifting equipment | Generally lighter, easier to manoeuvre |
| Best fit | Long spans, heavy loads, tight ceiling height | Shorter spans, lighter loads, budget-focused jobs |
In practice, the beam type that avoids a costly ceiling modification often ends up cheaper overall even if the raw material cost is higher, which is why a side-by-side quote covering both options, priced for your specific span and load, gives a more useful comparison than the per-foot material cost alone.
Typical Installation Timeline for a Single-Beam Project
A typical single-beam installation takes 1 to 2 days on site once engineering and the permit are approved, which itself generally takes 2 to 6 weeks from submission. The on-site work includes installing temporary shoring to support the structure while the wall comes out, setting the new beam and posts, confirming the connections match the engineered drawings, and removing the shoring once the beam is carrying the load on its own.
The framing inspection happens before any drywall or finishing closes the area up, which adds a short scheduling window but is not a step that can be skipped or compressed. Homeowners planning a broader renovation around the beam installation should build the engineering and permit lead time into the overall project schedule from the start rather than treating it as something that happens quickly once a contractor is booked.
What a Site Assessment Actually Confirms
A site assessment confirms the real span and load the beam needs to carry, measured against your home's actual floor and roof framing rather than estimated from a general rule of thumb. Two homes with the same wall length removed can need different beam sizes entirely depending on what the floor joists above are spanning and whether that wall is carrying one storey or two, which is exactly why a quote without a site visit is a placeholder number rather than a real one.
The visit also identifies the access constraints that change labour cost: how the beam gets into the basement, whether a mechanical or electrical run needs to be temporarily relocated along the beam's path, and how much of the existing ceiling needs to come down to tie the new beam into the structure above it. These details rarely show up in a phone estimate, which is part of why BaseWorks quotes this work fixed-price only after a site assessment rather than off a general price list.
Homeowners sometimes assume a bigger beam is always the safer or simpler choice, but oversizing adds material cost without adding usable benefit once the engineer has already sized the beam correctly for the actual load. The assessment is what prevents both outcomes, a beam sized too small for the job and a beam priced larger than the project actually requires.

Frequently Asked Questions
Pricing depends on the beam's span and load requirements, ceiling access, and whether temporary shoring is needed during the swap, which is why a site visit gives a more accurate number than a flat rate.
Not always. Steel typically costs more per linear foot but can span farther with a shallower profile, which sometimes avoids costly ceiling modifications that offset the material cost.
Yes. A structural engineer sizes the beam and the new point loads it creates, and that engineering is required for the City of Hamilton permit.
A single-beam installation with temporary shoring typically takes 1 to 2 days, not counting the engineering and permit approval that happens beforehand.
In most cases the ceiling along the beam's path needs to open to install and tie in the beam, though the extent varies with the existing floor framing.
