The beam over a garage door is typically referred to as a lintel. It is a load-bearing beam that supports the structure above the door. A lintel is typically made of metal, wood, or reinforced concrete, and each type has its own unique benefits.
Metal lintels are strong and can span greater distances; wooden lintels are lighter and more affordable; and reinforced concrete lintels are stronger and more durable. Depending on the type of garage door and its size, the lintel must be able to bear all of the weight above, including any garage door openers, the tracks, and any hardware attached to the door.
Professional installation of the lintel is important to make sure that it is properly secured and able to support the weight above.
What is garage door lintel?
A garage door lintel is a supportive beam or frame that is mounted across the top of a garage door opening. It helps to distribute the weight of the door evenly across the opening, so the door and the frame can remain straight and open and close properly.
Without a lintel, the frame may weaken and the door may not be able to open and close correctly. The lintel also helps to ensure that the doors are secure and that water and debris do not enter the garage space.
It is usually made from steel, aluminum or PVC and can be painted to match the door frame if desired.
How much does it cost to replace a lintel on a garage door?
The cost of replacing a lintel on a garage door can vary depending on the size and material used. Generally, a steel lintel can cost anywhere from $200 to $500, while a wood lintel can range from $50 to $100.
It’s important to keep in mind that this cost can change depending on what type of engineering is necessary and the type of finish needed. If you need to replace a large lintel or a lintel of an unusual shape or size, the cost can increase substantially.
On the other hand, if you get a standard lintel and do the work yourself, you can save a substantial amount of money. Additionally, you should always make sure to properly secure the lintel to the structure and check with a professional before attempting the replacement to make sure the structure is still sound.
What are lintel beams?
Lintel beams are horizontal support beams typically made of metal, concrete, or wood and are used in construction to provide structural support above windows and doors. They are found in both exterior and interior walls and can serve various purposes.
In exterior walls, lintel beams support the weight of the brick or stucco that is above the window or door, enabling the opening to be placed in the wall with a uniform look. In interior walls, lintel beams are used to support heavy masonry load such as stone, brick, or marble.
Moreover, lintel beams can also be used to level the wall above the opening, preventing the masonry from shifting to the side or crumbling due to gravity. Additionally, lintel beams enable the windows and doors to be evenly spaced, keeping the walls aesthetically appealing.
How do you fix a sagging garage door header?
Fixing a sagging garage door header requires basic tools and building knowledge. The first step is to identify the type of header installed on the garage door. If a wooden header is sagging, it likely needs to be reinforced.
If a steel header is installed, the best fix is to replace the header with a newer, reinforced model.
To reinforce a wooden header, you will need to first use a level to identify how much it has sagged. You should then remove the sagging header by unscrewing or cutting it out with a saw. To provide extra support, you can use a metal bracket or angle iron to secure the header to the concrete wall.
You may need to use longer screws and an impact drill to ensure proper attachment. For additional safety, use silicone caulk to seal the gap in the wall between the angle iron and the concrete.
After the header is properly secured, reinstall the header with nails or pocket screws. Finally, it’s important to seal the header with an exterior-grade wood sealer to help protect it from moisture.
With these steps, you can fix a sagging garage door header and restore your garage door.
How thick should a lintel be?
The thickness of a lintel will vary depending on the specific application and the load it needs to be capable of supporting. Generally, lintels will be constructed with a range of thicknesses. The minimum size that is recommended for a lintel is 100mm x 50mm, although this will depend on the specific load requirements and the span of the opening.
The maximum size that is recommended for a lintel is 300mm x 50mm, which should be adequate for the majority of openings. However, if the lintel needs to support a heavier load, then a thicker lintel may be necessary.
It is important to ensure that the lintel is chosen in accordance with the building regulations for the area, as this will ensure it is strong enough to support the load of the structure that it is being used for.
A manufacturer should be consulted when selecting the correct lintel size.
How do I know what size lintel I need?
When you’re determining the size of the lintel you need for your project, there are a few factors to consider. Firstly, the size of your opening needs to be taken into consideration. This will determine the length of lintel needed – a standard lintel is usually between 2-4m.
Secondly, you need to take into account the overall weight of the wall above the opening. The heavier the wall, the larger and stronger of a lintel you need. You also need to consider the span of the opening – for example, the wider the opening, the larger the lintel needs to be.
Lastly, you need to consider the type of masonry you are using. Different types of masonry require specific lintel sizes and strengths, so it’s important to choose the right lintel to ensure your project is a success.
How do you replace a concrete lintel?
If you need to replace a concrete lintel, you should follow the below steps to ensure safe and secure installation:
1. Make sure the area around the lintel is free from debris and remove any debris that may be present in the area.
2. Measure the opening so that the new lintel fits the space.
3. Cut the lintel to the appropriate size, making sure to use safety precautions such as wearing protective eyewear and gloves when cutting.
4. Place the lintel in the recessed area and mark the points at which the lintel will be connected to the surrounding brickwork.
5. Apply concrete adhesive at the marked points, making sure to fill any gaps for a secure hold.
6. Secure the lintel in place using wall plugs and screws.
7. Apply a sealant at the joint between the lintel and the brickwork to strengthen the connection and protect it from water damage.
8. Clean up any excess adhesive or debris from the work area.
Following these steps is important for ensuring safe and secure installation of a new concrete lintel. It’s also important to be mindful of working with concrete and other masonry materials: always wear adequate safety equipment and make sure the area is properly ventilated.
Additionally, it is advisable to enlist the help of a qualified masonry professional if you are uncertain with the process.
Can I raise the height of my garage door opening?
Yes, it is possible to raise the height of your garage door opening. Depending on your specific situation, you will need to take into consideration a few things prior to raising the height. This includes the strength of the garage door framing, the availability of materials to build a new frame, and any building codes or regulations that may apply in your specific area.
It is also important to ensure that you have enough clearance to avoid any collisions or injury when opening and closing the garage door.
If you determine that you have the necessary materials, space, and safety considerations to raise the height of your garage door opening, you will likely need to hire a professional to help complete the job.

Does a garage door need a header?
Yes, a garage door does need a header. It serves as a structural support for the opening and distributes the weight of the door when it is open and when it is closed. Without a header, the weight of the door is unsupported and can cause the walls or structure of the garage to become damaged or buckled over time.
Additionally, a header typically includes a track for the door to go up and down which is used for the motor or manual operation of the door. A professional should install the header to ensure it’s done correctly.
What size header do I need for a 8 foot garage door?
The standard size garage door header for an 8 foot garage door is 2-2x12s (two 2 inch thick 12 inch wide boards). You will need to be sure to have a ledger board attached to the wall studs that is flush with the top of the door opening.
The header should be securely fastened to the ledger board and the studs with wood screws or lag bolts. Once the header is in place, you will need to measure the amount of space you need to fill with additional support members.
If the span between the ceiling joists is wider than 8 feet, you may need an additional support member in the center of the span, depending on the type of door you are installing. for a standard double garage door, you should use two 2x4s at the top of the opening, and two more 2x4s at the bottom for additional support.
The header should be securely fastened to the support member with wood screws or lag bolts. It is always best to consult with a professional to ensure the header is properly sized and installed for the intended purpose.
What is rough opening for garage door?
A rough opening for a garage door is the opening in the wall of the garage that the door will fit into. Generally, the rough opening is slightly larger than the width and height of the garage door so that it can be easily mounted in the opening.
The exact dimensions of the rough opening will depend on the type and size of garage door you are installing. Generally, the rough opening is 2-3″ larger than the width and 1/2-3/4″ taller than the height of the door.
It is important to double check the measurements of the door when preparing the rough opening to ensure it is the correct size. Once the rough opening is constructed, the jamb and header should be installed along with the sill, and then the garage door can be set up and secured.
When constructing the rough opening, it is important to consider the type of material the door will be made of, the size of any windows that may be included in the door and any insulation that is to be added.
It is also important to make sure that the framing of the rough opening is stable, with no gaps, to ensure the garage door will be securely mounted in the opening. In addition, any existing tracks may need to be reinstalled or adjusted to achieve the desired result.
