Forum Title: Exterior door replacement questions
I am remodeling my house and will be replacing my exterior door. I have only 1/2 sub floor and am going to beef it up with 5/8 TG plywood on top of the 1/2. My question is Does the door extend down below the sub floor as mine is clearly cut out and around the sub floor and extends down below. Is this normal, or should i install the new door to sit on top of the sub floor?. I cant see it from my basement looking up because they installed a section of blocking at a weird angle. Any help is apprecaited.

What do the wood doors have on the exterior that would make them almost maintenance free I do like maintenance free AND energy efficient. Nada. Wood=maintenance any way you cut it. You can buy vinyl clad doors in a variety of colors (special order probably) and they would blend in with your exterior. They have a better instance of thermal resistance than wood or metal clad units. Does the sun shine directly on the door unit? If not, a wood door from Pella or Andersen would be just fine, but if it is in direct sunlight, no. Go with the vinyl clad.

Hi and thank you, my rough opening height from my 1/2 sub floor to rough in header is 83 inches width is 34. the door frame is 82 and feeling down through the floor looks like its another inch so 83 total. If i put down my 5/8 sub floor on top of my 1/2, i would need a 82 , Is that a standard size door? Or what ever you recommend, as i am clueless and not ashamed to admit it

A standard door is 80 tall. You still need room for the door frame, I'm not sure what the rough opening size is for a prehung door. I'm a painter, not a carpenter but I'm sure one of our carpenters will chime in later
