How to Identify a Load Bearing Wall

Need help identifying a load bearing wall? Here are a few tips to follow to see if such is the case:

Each and every house contains load bearing walls. These walls play a key role in supporting and reinforcing the building’s structure. Without them, the house could crumble down under the weight of the roof. If you have any major renovation projects, you must know where the load bearing walls are in your house.

Use the following steps to identify a load bearing wall:

Finding load bearing walls is not always an easy task. It all depends on the shape of the house, its size and the number of floors it has. With these clues, it is possible to recognize whether a wall is load bearing or not.

First step: hitting the wall. Knock (lightly) on the surface of the wall. If the noise you hear sounds hollow, chances are likely that you have yourself a regular wall. However, if the noise is muffled or dull, it might be a load bearing wall.

Another giveaway clue: the thickness of the wall. Load bearing walls are thicker than other types of partitions. They have a minimum width of 15 cm.

Climb up to the attic. If the wall is located directly under the attic, you can go up there to study the positions of the beams and joists. Load bearing walls cross roof beams in a perpendicular direction. Using this technique, you’ll get a better idea of the location of the load bearing walls in your house.

The wall contains large columns. Are columns strictly decorative? Not necessarily. The building’s architect may have used them to strengthen the house’s framework.

Outer walls form the skeleton of the house but in order for it to stay up, the building will need central pillars working to balance the weight of all the elements. That’s why walls that are located in the middle of the house have a better chance of being load bearing walls.

If a wall is located on the ground floor, go down to the basement to observe the ceiling beams. A wall that is set directly over one of those beams is probably not a load bearing wall. In order to be fully certain of what you’re seeing, pierce a hole in the ceiling, near said wall. The hole should be big enough for you to be able to observe the position of the beams. Once again, if they are perpendicular to the wall, this indicates that the wall is load bearing. This sign doesn’t lie and  you’ve got your answer
