Wow this is a video I really need!!!thank you!! I always hire at least 1 structural engineer and sometimes I get even another opinion before I make huge changes. One time 2 such experts told me it was safe to remove a chimney and the next morning I woke up to some serious deflection in a wide entryway. Had to run some lams across the entire span to fix the problem. Thank God it all worked out ok.

Lots of good info in here about load-bearing and non-bearing walls.

Great explanation of weight transference in a load bearing wall. You're right that removing interior walls growing in popularity as people want open concept floor plans as part of their remodel.

I really appreciate this video. Perfectly explained at the right tempo.

Thanks this is great. I am widening a door gap for a pocket door in the central hallway LB wall which is perpendicular to the ceiling and floor joists. Our code requires a 140x90 lintel checked into full length studs only, as I have a single story and a span of 1.85m and loaded dim of 2.89m and the studs are 90x45 on 450mm centres. There are already double joists under one wall so I will likely sister another floor joist between two inner bearers under the point load at the other side of the opening. The other thing I am then doing is putting in a 910 opening (no door) in a wall which is parallel to the ceiling and floor joists. As in your diagram there is a double joist under all the parallel walls. It is hard to tell if this wall is LB though. It has two ceiling joists above the single top plate and these are 100x50 and 50mm apart. The studs are only 70mm wide. The end of these ceiling joists sit on the exterior wall top plate and the hallway LB wall, (which incidentally only has a single top plate but has 90x45 studs at 450 centres). The hallway has a single 100x50 across the top plates and then similarly a pair of ceiling joists running from the opposite hall wall to the exterior on the other side of the house. So that small single piece is sandwiched between the two pairs. As the wall is only 70mm wide the pair of joists directly above only sit on the outer 10mm of the wall top plate as the joists are spaced 50mm apart. Given this small bearing surface is it likely that this is a non load bearing wall? Thanks

This is the best explanation about large openings on load bearing walls,thank you..Now i have a question,how long can the opening be and what kind of beam does it need if is not ingeneered beam.

Woah! That was the most helpful explanation/teaching! Thank you!

Hi, Awesome videos. I know you arent an engineer but.... I am wondering if I were to change an opening (parallel to joists) from 6ft, to a 10ft opening going from wall to structural wall, would that make it stronger since load is going where it is supposed to (as shown in your video here)? Also, this is the only wall connecting the center wall, which is load bearing, to the exterior wall, I imagine it is still structural in the lateral sense. Is an LVL beam at the top sufficient for lateral structure regardless of length? The opening is almost to the ceiling, so I figure opening it further will have no lateral structural impact. I hope I am asking this right. Thanks so much if you respond. Cheers

I’m not sure if this is a dumb question, but will it be and issue with any of these examples if the floor is concrete slab?

I got lucky..When I opened up all the walls in my house, the roof was a W or Fink truss. No load bearing walls!

Thanks

Can you explain Dutch gable roof on 3D The lay out please You are the best to explain things very clearly thanks for all the videos

Hello! How can we hide the beam if we are going to extend a roof on the opposite side so we have a clean open concept kitchen with out the beam or bull head.Thanks

Very helpful thank you for the knowledge!

I want to just take one 2x4 out of a wall to make a door opening, can I just add two jack studs and a 2x6 header?

Thank you, this was very helpful

Lvl. This building in your picture should have five peers down the building in the center

This video was awesome and very helpful

How would you do this at a marriage wall of a modular home? I have a cape cod home that I am looking at opening a 9ft area between my kitchen and living room and would like to install a flush lvl.

I sincerely need your help, the contractor put on board siding on the frame of the exterior house, but he did not add ply wood before adding the wrap (Tyvek) before putting on the siding. Is that normal that there is only Tyvek and siding to the out side framing. He has all ready started to put the insulation in the interior frame to close it up. Your help is needed. Help me with this question please. Thank you.

Can closet walls be load bearing?

I live in the desert and my house sits directly on a cement foundation. Does this mean I can install the support beam without worrying about over loading?

Hello what if I'm trying to close that entry and open the other side. Please help!
