new door install

[beckhamk]

I have a few questions on installing a pre-hung front door for our cabin.  Been watching some youtube videos and speaking with the homedepot person where we got the steel door from.

1) right now we have only the subfloor, no finished flooring yet. My question is do we need to install anytype of a sill underneath of the included threshold?  lowes video showed an added sill below the threshold and HD did not.

2) Should we put any weather stripping or sealent other than cocking on the bottom of the threshold when installing?

3) The pre-hung door comes with brick molding already. We will be tyveking the cabin for dryin and waiting till spring to side the cabin. HD person said we will jsut cock on the rear and top/sides of the brick molding to keep water out.   Should we be installing a drip edge of some sorts above the door at this time in addition to the cocking?

Shimming the threshold would depend on the thickness of your finish flooring. Something relatively thin and you can just put the unit on the rough floor with some heavy beads of caulk underneath. If you're planning on a great big thick carpet, or maybe thick cement board and tiles, you may want to shim it up a bit so the door clears your welcome mat...

If the door will be facing a lot of rain, a z-flashing across the top in addition to the caulk wouldn't be a bad idea. Flashing under the sill isn't a bad idea, either.

I placed the door on the subfloor. With 1/4" hardie backerboard and ceramic tile there is sufficient room for the door to clear a commercial type walk off mat inside the door.

    #1: You could use  pre-made pan , or use Vycor and Vycorners to create your own pan.  Or you could just bed the sill in caulk.

    #2:  Yes  , you could bed the sill in caulk, no flashing , no pan.

       



    #3:  You should put a head flashng above the brick mold , and you should tuck it under the house wrap .

     Similar to how this window is done on top, you'll be adding a piece of Z metal / head flashing. They sell a Z around here that is bent so it creates a 10 degree angle over the door or window.   A nice feature if you can local it in your area. They call it a "100" degree "Z" metal .


     


The bottom of that window is done wrong , the Vycor should have been applied to the rough open bottom sill, the window set on top of that "pan" , then the sides taped , and the top done last as the photo shows.
