Hello,
I just bought a steel door w/ frame.
I would like to install it in my basement
to make an entrance to my garage.
The wall is a hollow cinder block that is 3 and 5/8inches thick. But first I have to knock a hole in the wall.
The door frame height is 82inches tall and the ceiling is about 84 and 1/2 inches from the floor. leaving only 2 1/2 inches to work with.
I wanted to cement this door frame in place.

Does anyone have any helpful advice or tips?
I can't seem to find any info on this type of installation.
Is there a guide out there somewhere?

I don't want to use wood in the installation except to maybe temporary hold in place and not as headers or trimmer studs. Unless that is the norm, I don't know.

thanks
Jerry

It seems I'm alone on this one.
Well today I started cutting through
the cinder blocks and they are not hollow.
I used a circular saw
with a 7in masonary disc.
and I used my angle ginder alittle.
Boy what a lot of dust, no joke, my whole house has dust all over the place.
Warning for anyone attempting this it was pitch black in my basement.
I did use a plastic sheet to try to contain the dust but I did a bad job, really wasn't air tight. I definately paid the price for that. the wall is 3 5/8 inches thick so I could not cut through from one side. I had to cut from both sides cutting about 1 1/2 inch from each. I didn't finish cutting through all the way, it's difficult to a line the cut line from both sides of the wall, so I drilled plot holes and used some wood 1x3 7ft high,
securied to wall as guides.
Still didn't get the cut line the same on both sides, I'm pretty much disappointed.
I called it a day after 4hours or so.
I'll continue in a few days, not to **** my neighbors off, on account of the noise.
I'll update when I make so progress.
thanks for reading.

PS I'm starting to think may be I should have got a professional to do this.
Not that it's super hard but it's a headache to clean and worried about the final outcome.

Well yesterday,
I finished knocking out the wall.
What I did was,
In my basement I made a containment unit,
something like a phone booth, it's made of 2 x 3's and plastic sheets, duct tape, staple gun. It worked great to contain the dust.
Then I used a new masonary disc 7in to continue to make the cuts deeper, since the first one I used had worn away to about 4inches.

I also used a chisel and hammer to help knock out the wall.
I bought a sleg hammer but didn't use it.
The top of the wall came out in the size of brick sections. (using a regular hammer)
The lower half came out as a whole piece.

There are small problems such as, some bricks got broken off too much and will need repairing. 1 came out completely.
I also messed up by cutting the bricks in certain areas way off on account of the dark dust, I couldn't see through it.

I'll continue when I get some needed rest and sleep.

Now to dump the mess somewhere?
