So, what are LVL beams? They are a dense, high-strength laminated veneer lumber made of wood and glue, which are available in many different sizes. LVL beams are available in smaller sizes that can be easily hauled to a location by hand, and screwed together to form a larger heam that will meet requirements to carry a load.
The logistical benefits of LVL beams become clear when considering alternatives like glulams or steel beams, which are heavy and cumbersome.
Take a look at our video about saving a cove to get an idea of how LVL beams can be used. Planning for a proper installation is critical because the existing structure needs to be supported temporarily, before removing the existing wall that provides support.
I like to consider how much structure the temporary walls will be supporting, as well as where they will be transferring the load below. Sometimes this will require the services of a structural engineer. I also take into consideration how much working space we will have between the temporary support walls, and then measure, cut, and locate the LVL beams between them. By how to install a beam point, I have already prepped the walls, prepped for bearing posts, and planned ahead as to how we will how to attach pdf file to word document each LVL beam temporarily how to cut grass like a football pitch installing the how to install a beam posts.
Installing temporary support walls at this point is exactly like framing a wall. I like to locate each stud under a joist if possible, and use a double plate for added strength. For this project, we also installed support walls in the basement floor below, transferring any load to the solid concrete underneath. Once the temporary support walls are installed, the existing wall framing is removed. Instaall project is limited on space, so our support posts need to be installed after the beams are lifted into place.
I have found it very useful to employ temporary support posts to hold each beam in place as they are being installed. Once the beams are located in place, we measure, cut, and install the bearing posts at each end of the beam, coaxing them into place with a sledgehammer. Now install the king studs, and secure everything together using the appropriate fasteners.
All that is left to do now is secure the floor joists to the beam, remove the temporary support walls, and install floor joist blocking. LVL beams are dead straight, which was a big advantage on this project compared to glulam beams that usually have a crown. Not all space reconfigurations require structural beams, but in this case a structural support made with LVL beams was the most beaam choice. Here is a list of things to remember beeam installing LVL beams in circumstances similar to this project:.
If space is limited, make sure the LVL beams are in location before framing support walls so they are not boxed out. Identify and install temporary support how to install a beam so the structure will stay solid while work continues.
LVL beams do have structural limitations, so they may not always be the right choice. For our project, it was worth having the engineer run some calculations, and in the end—the LVL beams worked very well, saving time, money, and possible inwtall damage!

Create an Open-Concept Space by Removing Walls
Interior walls create privacy, define spaces, and sometimes bear the weight of the level above. These interior walls have defined floor plans for centuries, but starting in the s, when the open floor plan style became popular, many of these walls segmenting the house fell into disfavor.
New construction began to favor the "great room" look in which kitchen, dining, and living spaces were blended together into open-concept spaces. Today, a great many owners with older homes now find themselves wanting to remove some of those walls to create the modern open floor plan look. Opening up rooms by removing walls is one of the most coveted home improvement projects, one that returns instant value to the homeowner.
Larger, unsegmented spaces modernize older homes and nearly always result in greater home resale value, and in many ways, this can be a better project than building a full-fledged room addition.
With constructed additions, the towering cost is often not realized in resale value, but when you open up a room by doing the work yourself, you often find that resale value far exceeds the total cost of materials. This is a project that should be attempted only by expert-level DIYers, and if you don't meet that definition, you should hire a contractor to do this work. First, you must determine if the wall is load-bearing or not.
As long as the wall you intend to remove is not load-bearing, you can take it down with little thought toward structural support of the ceiling above.
But for load-bearing walls, it's an entirely different story. If the wall is load-bearing, you will need to carry the weight of the level above by other means, such as constructing a beam or buying a special laminated beam. It is important to remember, though, that while the beam carries the load of the ceiling above, all that load is then transferred at the ends to vertical post structures, created by a paired construction of king studs and jack studs.
Thus, the floor below those jack studs needs to also be strong enough to the task of carrying the entire load of the removed wall. Normally, this is not a problem, since the original load-bearing wall likely was built over an underlying beam or foundation structure below the floor. But in rare instances, it may be necessary to add some form of additional support under the bottoms of the jack studs.
At the very least, the jack studs should be positioned directly over floor joists to support the weight.
When planning a wall removal, it is always best to consult a builder or structural engineer for advice on the size of beams and the size and location of jack studs or posts. Plan on spending a full week on a project of this complexity. It is likely you'll need at least five full 8-hour days of labor when you include the wall and ceiling repair, as well as the final cleanup. If you live in a condominium, you may need to secure permission from the association board before you begin the work. And no matter where you live, it is nearly guaranteed that you will need a building permit to replace your wall with a support beam.
Verify if you need a building permit by calling your local permit office or checking online. Is your support beam sufficiently sized for the opening? Consult span tables or, better yet, hire a structural engineer to determine the proper dimensions of the beam you'll be adding. A beam that is undersized for the load it carries can be a very serious problem. Remember that plumbing or electrical services likely run through the wall.
Shut off the electrical circuit breakers controlling any circuits running through the wall, and use a voltage detector to verify that the power has been shut off. Electrical wires running through the wall will need to be addressed. Most likely there will have at least a couple of outlets and a light switch or two that you'll need to relocate. In many cases, it's a matter of moving existing wiring to a different portion of the wall or to a new wall.
If you feel even the slightest bit uncomfortable with electrical work, hire an electrician. If plumbing pipes run through the wall, shut off the water at the source before begging work.
Here, too, a professional plumber may be needed to reroute or remove plumbing pipes running through the wall you want to remove. Replacing a load-bearing wall with a support beam requires surprisingly few materials. This project is more about labor than materials. Especially critical is the beam you use. Wood glue is applied to all surfaces and the boards are tightly nailed together. Or, laminated beams are available on special order at your local lumber yard.
It is very important, though, that the beam itself, as well as the jack-stud posts on which the beam rests, are strong enough to hold the load of the ceiling above.
Your local building inspections office or a structural engineer, can verify the proper beam and post size needed to support the load. You will need also lumber sufficient to create two king posts and four jack posts. When you remove a load-bearing wall, you need to create a temporary support to bear the weight of the ceiling before removing the wall, which will remain until the beam is fully in place.
There are two ways to accomplish this:. In either case, it's critical that you provide horizontal supports at the ceiling and the floor for the posts to rest against, or else the posts may punch through the ceiling. Use a stud finder to locate ceiling joists, thereby ensuring that the posts will be squarely under the joists. To control construction dust, you can staple sheet plastic right to the wood. For a better dust-control solution, you can purchase an item called a ZipWall that telescopes up and presses the plastic against the ceiling.
Demolish the wall by gently hitting the drywall between studs with a sledgehammer. Light swings of the hammer will punch clean holes in the drywall. A line of these holes will allow you to pry back the remaining drywall from the studs. Or, you can cut the drywall into segments with a reciprocating saw, though this method creates a considerable amount of dust.
Make sure to wear hearing protection and eye protection when cutting with any power saw. Take care if electrical wires or plumbing pipes are present in the wall.
This is the point where you might need to call in an electrician to disconnect circuits or a plumber to reroute plumbing pipes. After removing the drywall, cut out the studs. Stud removal is made easier by cutting the studs in half in the middle, then prying away the cut ends. Be vigilant about removing the remaining protruding nails from the ceiling and floor plates. The horizontal ceiling and floor plates now need to be removed.
This is best done by severing the ends of the plates with a reciprocating saw, then carefully prying the plates away from the ceiling and floor with a pry bar. If there is a framed basement under the wall you are removing, remember that the ends of the beam will rest on jack studs that bear directly on the floor, and thus must support a considerable amount of weight. Make sure that those jack studs will rest directly over an underlying floor beam or floor joists If not, it may be necessary to reinforce the space below the floor to support the considerable amount of weight that will be carried by the ends of the beam.
Your assembly will be composed of four main elements:. The king stud represents the backing board for the ends of your beam. As with all other materials here, it has to be rock solid because it serves as the anchoring surface for the jack studs.
You might already have an existing stud in place that can serve as the king stud after demolishing the wall. However, because the king stud is such an important element, you may want to add greater strength to the assembly by nailing on a second king stud. This will produce a stronger, more stable assembly, at the cost of a slightly narrower opening. Measure and cut a full-length stud to run from the floor to ceiling, and position it in place between the floor and ceiling plates.
Use a level to make sure the stud is plumb, then nail it into place. Temporary support ledgers will need to be attached to the king studs, to hold the beam in position while jacks studs are installed.
These ledgers will hold the beam less than an inch below the final contact point along the ceiling. Measure the depth of your beam and then add an extra half-inch. This will give room to move the beam into place. Create the ledgers with short 2x4s or 2x6s cut to the width of your king post, then nail them into place against the inside face of the king studs. Nail holes do not matter since they are eventually covered up. Measure the inner distance between the two king stud. Square out cutting lines on all four sides of the beam with a carpenter's pencil and Speed Square.
You can cut your beam on an ordinary power miter saw. If the beam is too thick to be cut with the saw blade, cut as far as you can and then flip the beam over and cut from the other direction. The support beam can even be cut with a power circular saw or manual hand saw if you do not have a power miter saw. Whatever saw you use, take care to make the cut perpendicular to the face of the beam.
As with any home remodeling project, it is always better to have two people work on a project that requires heavy lifting. When heavy items are higher than your head, you have much less stability than if they were located below shoulder level. In addition, lifting heavy items high is a major cause of back injuries. This might be a good time to call in a favor from a friend or even to hire a laborer for a day.
If you are doing this work by yourself, start by having one person on each end of the beam and lift it level to shoulder height. Have one person lift their end of the beam, place the end onto the beam ledge or support column, and continue to hold it there for stability. Now, the second person can lift their end of the beam, swivel it into position, and rest it on the other beam ledge or support column. Temporarily secure the beam into this position for safety.
As you work, keep track of ceiling movement using a laser measurer to periodically check the distance between the ceiling above and the floor. Write this distance on one of the joists and occasionally check it to make sure that you are not losing any distance.
This way, you will know if the ceiling above is slowly sagging. With the beam resting on the beam ledgers, attach a pair of 2x4 side cleats to the king studs at both ends of the beam. Nail or screw these cleats into place so that they box in the beam.
This effectively creates channels on both sides of the beam, ensuring that you'll be able to lift the beam upward without fear that it will slip off the ledgers. The next step is to lift the beam into place so it rests firmly against the ceiling. This can be done by having a helper lift at each end of the beam. Another method is to position a temporary post in the center of your beam and use a car jack to raise the beam and lightly press it up.
