No, not every wall needs a beam. Whether a wall requires a beam depends entirely on whether it is load-bearing or non-load-bearing.
Generally, a strong material would thrust more load on the ground. Therefore walls made of heavy-weight materials would certainly need beams.
Many houses are built without internal load- bearing walls. In these cases they would have beams and roof trusses that transfer the load to the external walls. You could ask your contractor to explain why he has come to his conclusion, otherwise a structural engineer would be able to give you some answers.
To tell if a wall is load-bearing, check its orientation to the ceiling or floor joists. If the wall runs perpendicular (at a 90-degree angle) to the joists, it is almost certainly load-bearing. You can also confirm this if the wall sits directly over a foundation beam in the basement.
Yes, a 2x4 wall can absolutely be load-bearing. In fact, the vast majority of older homes (and many newer ones) rely on exterior and interior 2x4 walls spaced 16 inches apart to support the weight of the roof, second stories, and floor joists above them.
2x4 on edge may bend or fail under heavy loads; fastener pull-out is common. A wood 2x4 on edge spaced 16 inches on center typically supports moderate loads but hanging a 250 lb fixture risks bending or failure. The load capacity depends on wood species, grade, and span length.
What Thickness Drywall Should I Use for Walls? The most common choice for interior walls is 1/2-inch drywall. It offers a good balance of weight and strength.
Usually, if a wall runs parallel to the floor joists above, it won't be load-bearing. Meanwhile, if it runs at a 90-degree angle to the joists, there's a good chance that it is. Just bear in mind that this won't always be the case! It runs all the way through your home.
Consequences of Removing a Load-Bearing Wall:
Compromised structural integrity. Sagging floors. Possible catastrophic collapse.
Step 1: Check Your Home's Blueprints
Check out the framing plan and basement floor plan. These spots will give you an idea of joist direction and may even label your load bearing walls. “Blueprints are always a great place to look. It's going to show you not only a lot about the structure, but any changes to your home.
Contact a builder, a structural engineer or surveyor. They'll be able to correctly and accurately identify which walls are load bearing and advise you on your renovation plans.
Non-load-bearing walls support only their own weight and serve to divide space. Common examples include closet walls, bathroom partitions, bedroom separation walls, and basement partition walls. These walls run parallel to roof trusses or floor joists and do not hold up the ceiling or roof.
If the wall runs parallel (they run at the same angle and so will never cross) to the floor joists above it, it is probably not a load-bearing wall. If it runs perpendicular or at a 90-degree angle to the joists there is a good chance that it is a load-bearing wall. The wall crossing the joists provides support.
Replacement support is mandatory — Structural support must be in place before removing the wall. It's necessary to have a plan in place; otherwise, your home will start to sag over time. Know your beams — For this type of project, a heavy-duty beam is needed if you are looking to fully remove a load-bearing wall.
Beams are structural or optical elements that manage weight or direct energy. In construction and engineering, they are categorized by how they are supported:
A 20-foot beam typically costs $150 to $700 for the material alone, depending on the type of beam. When factoring in engineering, permits, and professional installation, the total project cost generally ranges from $1,000 to $4,200.
Architects: Architects are knowledgeable about architectural plans and may be able to recognise load-bearing walls based on the original design. However, their assessment might not replace the need for a structural engineer's evaluation.
The cost of hiring a professional builder or structural engineer to provide their expert opinion on load-bearing wall analysis can cost you between £300 and £1000, depending on the level of complexity of your house improvement project. In some situations, you may be able to get a free consultation.

2x4 bearing walls are used all the time for interior and exterior wall bearing with no problems. The only time other than 2x4 wall studs are used is when there may occur the need to install ductwork, piping or conduit inside the stud spaces and a standard 2x4 wall is not wide enough.
It has a beam, column, or other wall directly below it or following its exact path. It has purlin bracing attached to it. If the floor joist boards run perpendicular to each other at a 90-degree angle, it might be load-bearing. It is likely load-bearing if it is perpendicular to the ceiling joists.
If your doors and windows no longer open, shut, or latch properly, and diagonal cracks have appeared at the corners, you might have an unrepairable house.
Typically, a load-bearing house is limited to G+1 or G+2 levels, whereas RCC can easily support buildings with five floors or more. In terms of durability, well-designed RCC structures offer a lifespan of 75–100 years, provided they are properly maintained.
Here are other ways to tell if walls are load bearing.
The average cost to remove a load-bearing wall is $5,700, but the price ranges from $1,400 for a wall in a single-story home to upward of $10,000 for a wall in a multi-story home. Removing a load-bearing wall requires serious structural considerations, and you'll need to hire the right pros.
Non-load-bearing walls carry only their own weight and may be any one of the types discussed under load-bearing walls. This type of wall is used to close in a steel or concrete frame building. It is usually carried by supports, normally steel shelf…
