Door Jamb

boxcar955 | Posted in Construction Techniques on August 18, 2006 01:37am

I have a client who bought a door and jamb from  Menards. They painted  door looks good now the problem is it is a jamb for a 4inch  wall and it is a 6 inch wall it was installed by them selves but to trim it out you need widerjamb any suggestions Menards wants just as much for new jamb as they do for door and jamb combined.

    If it is a painted jamb just add some extensions, like a 3/4"x1 1/2" popular or hemlock glue it nail it fill the seam and paint.

      i don't think this will
      i don't think this will correct the sagging of the door. which creates the gap.

    Is this an interior or exterior door?

    I'd be tempted to build a new jamb for an interior door, shouldn't take to long and looks better then extenstion jambs IMO.

    Worst case is to make some jamb extensions

        Jamb extensions are the answer. 

        But here's a tip.  If the door jambs came with brickmold already on it, take it off.  Install the door flush with the INSIDE wall.  This way the hinges will be proud of the interior wall as they should be.  Then apply your jamb extensions to the bring the door flush with the outside wall.  Re-apply brick mold.You get out of life what you put into it......minus taxes.

    Jamb extensions and a sill extender will fix you up.

    All you need are some extensions on the inside to come flush with the sheetrock. Hold the extensions back from the jamb edge with a reveal, just as you would with a casing. They have to fit behind the hinges which will make the reveal about 5/16" - 3/8". This also keeps the swing of the door from hitting the extensions.

    Allowing customers to pick up the material is always a bad idea. I ran into an install like yours where the customer bought the door from the discount rack. The door must have been hit by a truck, twisted, and the jamb was the wrong size. What should have been an hour job turned into half a day. The customer saved $50 on the door but paid an extra $200 for the install.

    Beat it to fit / Paint it to match

      the sill extender generally goes to the out side..

        If the six inch wall already has the four inch door installed, all you need is an interior extension jamb and that doesn't require a sill extension. Way back when 2x6 framing was somewhat new, door manufacturers offered extension kits for their four inch units. These would include an extension for the sill and were also an area that could be subject to leaks, depending on how the extensions were attached. Pan flashings were not commonly used, although they are just a back up. These days you just order the door for the thickness of your walls. Trouble is, they only come in two sizes. If you use something other than 7/16" sheathing, apply foam board under the drywall, have masonry or anything, other than the norm, you have to be a little creative. Making minor adjustments on the interior may reduce exterior weather issues. From past experience, i'd avoid exterior sills with a joint. The better doors have solid sills in both sizes. Jambs built for 6" walls actually have 6" of sill exposed to the exterior, beyond the door. That's a pretty big semi-flat spot and not a place where I would want a joint, especially a caulked joint. With some wider interior extensions, you may have to use thin material, bevel back and maybe alter around the RO so it doesn't interfere with the operation of the door. The lock strike often hits the interior extension and scratches it. It's easy to form a piece of brass sheet for that area, almost looks normal.Beat it to fit / Paint it to match

          Interior extensions don't allow the door to open as far."Citius, Altius, Fortius"

          it sort of looks like the door is sagging from the head jamb. sorry if i explained it incorret. but the door is flush with the wall, so i wont need a door extension. it just looks like its sagging from the head jamb.

      i paid full price for this door at the big store called lowes and it was the best one out of the bunch.it should not be sagging like that. maybey i should of grabbed the worst one.i might of had better luck.
