new door through triple brick wall
I have a 1929 Dutch Colonial in the Detroit area, and would love convert a little-used room behind my garage into a mudroom. Doing so would entail a new doorway through the back of the garage into this room.

After doing some investigation, I realized that rather than brick veneer and wood framing, the wall consists of 3 courses of brick. No wood. There is a second story above the area.

I'm going to hire someone for the project, but want to make sure it's done right.

1. Is a mason alone qualifed to do this?
2. What manner of lintel do you suggest?

3. Elsewhere the house has a steel door through brick without wood framing. Could I used this approach in this application?

A good mason contractor should be qualified to do the job. It will need reinforcement on the sides and top. A 1/2" steel 'L' beam should support the structure above. I do not recommend making the opening without side reinforcement of some type. The doorway you mention may have been built before codes.

Thanks for the reply.

I met with a mason who told me a lintel is not required... he's out.

What about a separate lintel for each course? That way one course could be addressed while the other two are bearing the load.

Would a 2x12 rough frame outside a prehung fiberglass door suffice on the sides?
