5-1/4" door jam?

cbzdel

I am replacing the complete whole frame because the current wood is damaged and starting to rot (the rot is isolated to the door frame and does not effect the structure at all)

Otherwise I would just do a slab door.

so, what you need to do is purchase a door with a 6 9/16 jamb (which is for a 2X6 wall framing material) and either you cut it down or have it cut down for you.

Lowes can get you special sizes if you want them to do it for you.

For you to cut it down, you would need to remove the brick moulding and cut back the side and top boards to whatever dimension you need and then reinstall the brick mould.

It is better to cut down the 6 9/16 that use a 4 9/16 and an extension IMO.

Sorry but I disagree, unless you disassemble the frame so you could trim it on a table saw, it will be very difficult to get an even cut. Adding extension jambs is much easier.

to each their own.

I’ve put in doors that came from Lowes with T&G jamb extensions.

The jamb on the door had the groove and the extension had the tung.

Put in the door rip the extension glue in and done.

you know,if this door is in an exposed location you may be better off using a jamb made out of a composite material,in that case id special order it

nope, covered porch

I bought the door for a 4-1/2" wall.

While at the hardware store I spoke to the door "specialist" and he told me what he recommended. He said remove the brick molding and trim the brick molding in a table saw to the correct thickness then reattach it, then use your own trim on the outside of the door, trim that matches the rest of your house.

What do you guys think? It makes since to me, as the brick mold looks nothing like the rest of the trim on my house.

if the origional door was under a covered porch ...why did the frame rot?

rjniles

You are going to cut the brick mold down to use as an extension jamb? Why?

Use 1" clear stock or composite trim board

the door is the original door from the 40's, a covered porch was built within the past 3 years.

figured then I would not have to buy any wood, I have lots of exterior trim left over, it seems as I could just run the existing brick mold down a table saw and my problem would be solved. If its a bad idea I will stay away.

kwikfishron

It will work just fine.

Usually the brick mold is finger jointed pine. When you mill it down small enough to use as an extension jamb it will be very flimsy at the joints. I would use a composite board to cut the extensions and composite exterior trim. But as NAP said; "to each his own"

you know you can buy a 2500$pre hung door and unless you specify they always put them in those 15$ frames,that fj white ''wood'' is junk
