I want to put in a larger doorway entrance to my shop.I’m planning for a 48” or 60” door and it will be pre-hung.My shop is all brick(4×6x16).Shop size is small 12×14 and where I want to place the new door allows me to use patio space and roll some equipment outside to work.The inside is not framed or furred out,I will be cutting out the opening for door placement.How would one attach this pre-hung door to the rough opening?.Do I need to frame it out with a header?.How would one attach the wood to the inside opening of the brick?. Thx.,Jeff

Howdy Jeff
I think I would frame that opening just as you would a stick frame building. That is using king studs, lap studs and a built-up header. I am assuming that your pre-hung door has a built in threshold. If not keep in mind that when your door is opened there will undoubtedly be a little sag. Check the floor level at the wall and all across the “swing”of the door then set your header and the highest level of the opening.

If you chose to “sub-frame” your opening in the above manner I am sure you can simply concrete nail into the brick or at worse will need to use some type of “anchor” in the brick. You might also think about using construction adhesive along with your mechanical fasteners in the “sub-frame”.

Sometimes my written instructions are not all the clear. If you find the above confusing feel free to e-mail me with more questions.

Pictures, please. I can help with this but I have to know what you have to start off with. Yes, you still need a header over the opening and if there’s brick above the doorway, that needs to be supported. If this is solid masonry, not brick veneer with frame construction inside, then you’ll be fastening pressure treated 2-by-(something) to the masonry. Your choice of masonry anchor depends largely on the type of masonry you’re trying to anchor into.

Have your say...
