I am moving changing a door to a window. So I hired a concrete contractor to remove the door and build up the bottom and frame the window, followed by a window installer coming in to install the window. Simple right? No...
As soon as the concrete guy arrived after two hours he told me he could not remove the door frame. He could not find anywhere along the door frame screw holes or nail holes whatsoever and he is unable to pry the metal frame off the exterior wall.
I drove to the site to see it and called a carpenter friend of mine to meet me there.
In examining the door frame I could see no visible fastener of any kind. My carpenter friend said he has not seen this before but it looks like they custom fabricated the entire metal door frame in one piece then embed it in solid concrete.
At this point the door frame is so beaten up but it's not coming out.
My concrete contractor says he can try using a concrete saw to saw off the
8" solid concrete wall to which the frame is embedded in, and I am thinking may be he can just lay his concrete blocks and notch the end for the door frame, then pour solid concrete to fill in the notches. However this will create complications too when it comes to the window frame. Dade County requires rebars to be placed on either side of window tied to the tie beam and slab below, and fill in any void in concrete blocks with solid concrete etc...Here are some pictures:
Also, now that I know it's done this way, I was planning on replacing all the exterior doors in another phase of the project. guess I am not going to be able to replace the frame so I would need to get custom door to match the frame and hinges?
and how would they have leveled the frame if it's installed in one piece with concrete, no shim at all.
I kept finding many "unconventional construction method" in this place, that's really puzzling, causing tons of delays and "change orders", and now, I have half a dozen window and door openings, with tropical storm Noel blowing nearby.
