Things To Consider About Brick Wall Lintel Before Installing It

Installing a brick wall lintel doesn’t require you to be a professional. But, there are a few things to consider before proceeding with the installation. We have provided the necessary considerations you need to make b efore this DIY project begins. Take a look at them:


The width of the lintel depends on wall thickness. The depth of the lintel is 1/9th the span length. If the width is 9 inches and depth is 4 inches, the size of the lintel is 4×0.9×0.4. You must know the size of a brick lintel before you instal it, in order to maintain the proper alignment. And to ensure there’s no gap like the gap between tub and floor tile found in the bathroom.

Types Of Brick Wall Lintel

There are essentially two types of brick wall lintel. Now knowing the type of brick lintel will help you determine which one you want to use for your window. We have discussed in detail about the two types of wall lintels.

Brick Lintel

These lintels are hard and well-brunt with sharp and square edges. The depth of the brick lintel varies with the size of the opening between the walls. The appearance of brick must be multiple brick courses typically 10cm, 20cm, etc.

When bonding frog bricks, the cement mortar with a mixture proportion ratio of 1:3 should be used. Also keep in mind, for heavy loads, brick lintels can’t be used.

Reinforced Brick Lintels (R.B. Lintels)

These lintels are similar to brick lintels but good quality bricks are used. They last longer than brick lintels because they are reinforced with steel bars.

For inserting steel bars and rods, 2-4 cm wide space is kept. The bricks are arranged in a parallel pattern. Soon after the steel bars and rods are placed, it’s filled by pouring mortar.

Cost Of Brick Wall Lintel

The cost of installing a brick wall lintel depends on the price that you’re willing to pay. It can even be a part of the cost for furnishing your whole house

The installation cost for brick wall lintel is around $350-$400. Getting professional assistance would definitely cost you more for installation. The repair cost of brick wall lintel ranges from $650 to $1,000.

  • Utility Knife
  • Mansory Cutter

Now that you’re prepared with tools, let’s get started!

Step 1: Taking the Measurements

Taking measurements is part of most installation processes like installing wall cabinets.  First, determine the site where the window will be installed. It’ll help you develop a perception of the angle at which to install the lintel.

Use a measuring tape to measure and mark the spots where you’ll install the windows. Length, width, and the center of the wall should be measured. 

Step 2: Drilling Holes and Taking Out Bricks

Start drilling holes from the opposite side which is easier. The bricklayers are easier to remove from the inside and take much less effort.

Drill holes on the marked locations on both sides of the wall. Measure the size kept for the lintel and window.

Use a masonry cutter to cut in a straight line on two width points. After cutting the brick binding material, take out the bricks from the place you are going to install the lintel.

You’ll find quality masonry cutters from our suggestions below-

Step 3: Removing the Inner Bricks

With the help of a brick hammer and pointer, take out the bricks of the wall. Remove inner bricks by using a brick hammer from the inside.

Make holes around the window frame before installing it. Use a measuring tape to measure the length of the spot where the windows will be installed.

Step 4: Installing the Lintel

Now it’s time to place the lintel in its place. Mix cement and sand with red dye. Then apply this mixture to the broken edges on the wall. This will make the wall equal to the pry bar.

Measure the size of the lintel. Then wrap it with a plastic sheet or metal wrap before you place it in its place. Now put the lintel in its place and put heavy blocks over it and in front of it.

Cover the lintel completely and make it look load bearing. Now start permanently attaching the lintel to a brick wall. Bind threads to the lintel according to its size and fix it.

Step 5: Finishing Touches

Use the binding agent and fix the lintel with the bricks. You should follow the same method from inside of the walls. To hold on to the bearing use a supporting rod in the middle of the opening space.

There you have it! The lintel is installed on the brick wall.

If you can make your bricks look old, then installing this is easy for you.


Question: How do I know what size lintel do I need?

Answer: Brick length is used usually when the load is less and the opening is less than 1m. Depending on the span, the size of the brick lintel varies from 10cm to 20cm.
