Load bearing wall?

If you were removing a load bearing wall you would need a temp wall on each side of the wall no more than two feet from the wall being removed . Since you are putting an opening in the load bearing wall (like a doorway) you really don't need a temp wall. As long as you are not disturbing the support beam. The beam and remainder wall will support it. Keep in mind you will need to install a header in the opening to take up the stress. It also depends on how big of an opening. If the opening is wider than double doors then I would put up a temporary wall on the side away from the other wall.

Hi Michael I still would throw up a temporary wall just to be safe. Even if its just a couple of 2x4s with a 2x4 across the top. A little support can go a long way - might as well do it and give yourselves the peace of mind.

Just renforce the doorway

A header above the opening and the framing around the opening should be enough if you are talking about a window or doorway. If it is a substantial portion of the wall, I would use temporary support anyway.

Short answer? Yes. It's a structural/safety issue.

If you are only putting an opening (like a window) you will be fine as long as you case it properly. Think of it in terms of windows in an exterior wall on a house.

Honestly what you need is a structural engineer and a contractor to take a look as advice online may not be appropriate for your particular situation. It's best to keep your house standing, please hire the pro's for exact advice.

Yes you do need one. This is a safely issue. If in doubt ask someone who does this for a living.

For safety purposes it is better to be safe than sorry. You do not need anything crashing down on you. Be careful not to cut out the beam, you need that support to hole up your roof.

I would get a contractor to take a look at this situation and advise you, they have seen much more than you can imagine with as many results,both good and bad. Best to be safe and not sorry.

I think it would depend on how big your opening is on the original load bearing wall. If it's a small door, you may not need one. But if its more than half of the wall, then you should put a temp in. With projects like this, its always better to be safe than sorry!!! Think about worst case scenario - would your home owners insurance cover anything if you moved your load bearing wall without a temp?
