By Michael Franco and Bob Vila. Doors come in countless different sizes and styles—from modern, flush interior doors with standard dimensions to massive, traditionally designed entryways. By comparison, there are dramatically fewer installation methods; in fact, there are only two. The following tips can help you avoid common setbacks.
When you set out to install a prehung door, begin by measuring the rough opening into which you are placing it. The opening should be one or two inches larger than the door itself. That wiggle room enables you to shim the doorbringing it to the level-and-plumb position critical to proper functioning.
Set the door into the rough opening. Has flooring not yet been installed beyond the threshold? Next, make sure the hinge side of the door is plumb, meaning perfectly vertical. Having checked that the door is still centered within the opening, stabilize it by adding shims to both sides, near the top.
Check the alignment using a level. Go on to place shims in a few more positions along the hinge side; check level once more; then nail through the jamb wherever you shimmed. Close the door and confirm that its top portion is level. Make adjustments by shimming the latch side of the door. Continue tinkering until the reveal along the top is uniform.
On the what size umbrella for outdoor table side of the door, bring the jamb how to install games on a school computer to the adjacent drywall. Once finished, nail through the jamb where you have shimmed. Now place additional shims six inches from the bottom of the door, as well as above and below where the strike plate will go.
So long as the reveal remains uniform, proceed to nail the jamb at each position where you have added shims. To finish, go ahead and put a few more nails through the shims you nailed previously.

Mar 08, · Prehung doors hang on a jamb that is “split” into two pieces. The door is attached to the main jamb, which is installed first. The split jamb has a groove under the stop so it can slide over the edge of the main jamb. .
In those days, he'd assemble the jamb, hand-cut the hinge mortises, and hang the door separately. A prehung door is a unit that comes with hardware and a frame, ready to be installed into a doorway. These doors and jambs must still be carefully adjusted to account for shortcomings in the wall frame. Back when carpenters assembled the parts around a door piece by piece, they could easily customize their work, make changes, or correct problems. With a prehung door, however, most of the assembly work is done off-site, so a mistake made when you place an order can turn a perfectly good unit into worthless scrap.
Here are two steps for avoiding that outcome. If the opening already exists, check that the trimmers are plumb, parallel, and square to the wall and the header. So rather than answering directly, say instead which side you want the knob to be on when opening the door toward you. The door is attached to the main jamb, which is installed first.
The split jamb has a groove under the stop so it can slide over the edge of the main jamb. Typically, both jambs are furnished with casings already attached. Tip: If the long screws don't match the ones that came with the hinges, install them behind the hinge leaf. The trick is to adjust either the opening itself or your door-hanging technique. Just plumb the hinge and latch jambs with a level or a bob and hold them in place with shims.
There will be a gap between the casing and the wall, so cut a piece of wood to fill it. More than that, and you may need to modify the jamb. Remove the screws that hold the drywall to the trimmers, then coax the trimmer ends into the wall with a sledgehammer. Toenail them back to the sole plate, cut the plate back flush using a reciprocating saw, and reattach the drywall screws.
In those cases, reframe the opening or order a smaller door. To correct this, add a third shim to the standard opposed pair. Slide the third shim back and forth under the other two to change their angle with respect to the trimmer.
