Beam installation costs an average of $3,284, but prices can range from $225 up to $10,400 depending on a few factors, like the type of beam you need, the length, and more. You can expect to pay between $3 and $40 per linear foot of beam you need, with steel beams totaling between $6 and $20 per square foot.

Type of Beam

The type of beam you need will have a significant impact on your beam costs, as some materials are up to twice as expensive as others. Traditional wooden beams, LVL beams, aluminum, and steel beams fall on the lower end of the range, and engineered wood and glulam beams are some of the most expensive.

We’ll include typical pricing for each type of beam in the table below but note that these might not all be options available to you. You should contact a local structural engineer to help decide which type of beam is right for your project.

Beam TypeMaterial Cost (per Linear Foot)
Aluminum$13–$30
Engineered wood$3–$40
Glulam$5–$40
LVL$3–$12
Steel$6–$20
Traditional wood$5–$30

Size of Beam

Since support beams often include pricing by the linear foot, it’s probably obvious that beam installation costs can vary by size, too. Longer beams will not only require more material and labor to install, but they can also be more challenging to deliver, which can drive up delivery costs. The average cost per linear foot for beam installation is around $17 per linear foot for materials only, but prices can range from $3 up to $40 or more depending on the material.

The table below includes pricing based on beam size, but note that beam thickness will also play a role. You might need to upgrade to thicker beams to support more weight or span greater distances to create a more open floor plan. Again, speak with a structural engineer to figure out which beam size is right for your project.

Beam Length (ft.)Avg Material Cost
10$170
20$340
30$510
40$680

General Contractor Costs

Beam installation requires help from a professional—often a general contractor—because it’s a structural component of the home. You can expect to pay between $60 and $400 per linear foot for labor for beam installation if you hire a local general contractor.

It’s crucial to note that this is the price for the beam installation only. It doesn’t include removing a load-bearing wall, replacing and refinishing drywall after the installation, or any other form of buildback to return your home to its original condition. You’ll have to budget separately for these line items.

Structural Engineer Costs

Most projects that involve installing a beam or replacing one will require help from a structural engineer, as they’ll need to draw up building plans or sign off on plans from an architect to ensure the construction is safe. Structural engineers cost between $350 and $500 for this type of project.

Additional Pros to Consider Hiring

Before you move forward with beam replacement, you may want to budget for some other professionals who can help bring your home back to its pre-construction condition.

Cost by Location

The majority of your beam installation cost will go toward labor, so your costs will vary quite a bit based on your location and the cost of living in your area. You can expect to pay more for beam installation in high-cost states or in and around metropolitan areas to account for the higher cost of living.

StateAverage Cost
California$4,720
Florida$3,380
Georgia$3,000
Illinois$3,130
Michigan$3,000
New York$4,080
North Carolina$3,210
Ohio$3,100
Pennsylvania$3,140
Texas$3,030

Additional Cost Factors

There are a few other things that can affect your budget that you should consider if you want the most accurate estimate possible.

Project Type

Generally speaking, there are two kinds of projects that may require beam installation: a renovation project that includes a change to the footprint or structural loads of your home and new construction. Installing a beam during a new construction project is significantly easier because your contractor doesn’t have to cut away, replace, or relocate drywall, insulation, or plumbing and electrical lines. As such, you can expect installation costs to sit closer to $1,253 for new construction.

If you’re installing a beam as a part of a home renovation, not only will your contractor have to work around building materials, but you’ll also have to budget for buildback after the installation. In that case, your total is likely to push closer to $5,347.

One of the most expensive types of beam installation will be for the main beam. The cost of replacing the main support beam in your home averages around $3,250 but can reach as high as $25,000. Accessibility to the beam you need to replace is a major factor, so you’ll see lower costs if you’re replacing a beam in an exposed pier and beam foundation, for example, than you would if replacing a beam surrounded by building material and interior finishes.

Demolition and Prep

Beam installation as a part of a home renovation or add-on will often demand some demolition to expose the area where the new beam will sit, which can increase costs a bit. If you’re replacing a beam in your home, as is often the case when installing a steel beam instead of a wood beam to open up your floor plan, your contractor will also need to do some prep work beforehand to ensure the structural components remain supported while they’re working.

Demolition and prep work can vary widely in price depending on the extent of the work you need.

Post-Construction Cleanup

Many general contractors will include some level of post-construction cleanup with major construction projects like beam installation, but you’ll need to check your contract to see if yours does include it. If not, you can expect to pay somewhere between $270 and $700 for an in-depth cleaning after installation.

Beam Delivery

Beams are long and heavy, so delivering yours to your home isn’t always a trivial task. For smaller beams under 20 feet, your contractor will often be able to bring the beam to your home using a standard truck. For longer or heavier beams, you’ll likely need delivery on a flatbed, which will cost you more for the specialized equipment. Expect to pay between $100 and $370 for beam delivery if your materials are longer than 20 feet.

Permits

Finally, most projects that require beam installation will include structural changes to your home, which will require building permits. Permits for beam installation will often cost between $100 and $500, depending on where you live. Some municipalities charge for permits based on a percentage of the total construction cost, so your permits could be more expensive if you’re installing a beam as part of a larger construction project.

Support Beam Replacement vs. Repair

For homeowners who have damaged beams in their homes, the question of whether it’s better to repair or replace the structural component is an important one to consider. In most cases, repairing by installing additional supports to take loads off of the damaged beam will be less expensive and less intrusive, but it may not last as long as a full replacement.

You should speak with a structural engineer in your area to see what the best course of action would be.

How to Save Money on Beam Installation

With beam installation costs reaching as high as $10,400, you may want to explore the following options that can help you save some money in the process.

  • Consider a repair instead. If you speak with a structural engineer and discover that beam repair would be a safe alternative to replacement, this option will usually save you money, as it takes less materials and labor to complete.

  • Choose your material carefully. Beam costs range widely depending on the material, so choose the most affordable option that an engineer confirms will suit your project to save money. For example, you could pay $20 less per linear foot for the cost of an LVL beam than you would for an engineered wood beam.

  • Get the work done by a structural engineer. You’ll need a structural engineer to design your beam for you, but you can choose a general contractor to do the installation. If your engineer is also willing to do the physical labor, you could save a bit on labor costs if you guarantee them the entire job from start to finish.

  • Tackle the buildback yourself. While you shouldn’t attempt to install or replace structural beams in your home, you can DIY some of the work to reduce labor costs. Consider tackling things like drywall repair, repainting, and post-construction cleanup to save some money.

Frequently Asked Questions

In most cases, no, it’s not legal to install a beam yourself. Most municipalities require certified professionals to tackle any structural work within a home or commercial building, so installing or altering structural beams isn’t suitable for DIYers. Instead, consult a structural engineer and a general contractor to get the work done safely.
