Tim Great video, thanks. A question:

In all cases should the base of the new rough opening be close to flush with the interior floor?

Thanks

@jakeerussell I believe what you want to know is this: The BOTTOM of the door threshold should be at the top of the finished flooring. I used to put in a scrap piece of 3/4-inch plywood under my doors as most of my finished floors were that thickness.

I'm really wondering why he's touching the pink fiberglass with bare hands. I have touched it on occasion by accident, and it gets in your skin and is extremely itchy...

[AsktheBuilder]

@Jemmeh That's because my hands have callouses on them. Perhaps yours don't because your rarely use them for heavy work. On other parts of my body fiberglass can be an irritant. Some people are more sensitive to the glass fibers than others. Perhaps you're one of these.

Thanks for video. That waterproof sticker is new thing for me. We only use foam in Estonia. Do u put that sticker elsewhere too?

I'm enjoying all your videos, but your viewers should know that you should always handle fiberglas with gloves and then wash with warm water and soup afterwards. Even small amounts are dangerous and those tiny particles can get in your hair, lungs, eyes, and cracks in your skin without you even noticing.

Nice video, but I wondered what advice you could give about the frame being attached to a brick wall, ie you put the waterproof sticker stuff on the frame and the wall, and then you said you would put wood over it to cover it (and match it with the rest of your house I guess). My house is red brick and so I doubt that silver waterproof sticker will be suitable. What can you suggest I use to cover up the foam between the frame & the wall as it will be visible otherwise.

Thanks for your help

I want to know if you need to use J-channel all the way around the door where the trim meets the siding (I have aluminum siding that I willbe cutting away for the installation of a new exterior door).

you should wear gloves when handling firbreglass mattting. if you dont your hands will itch for days as there willl be tiny chards of glass in your hands. other than that great video

@hoopfan71 If your flashing is self-draining, caulk can block the exit of the water. You can caulk the interior of the door to stop air infiltration.
