how to install a pre-hung door?

Answer 1

You will need:
Hammer
Small wood shims you buy in a pack.
8p finish nails
6p finish nails
Nail set
Level
Pencil
Measuring tape

First, unpack the pre-hung by carefully pulling out staples, nails, etc... and seperate the outer casing and jamb. The door will always stay on the jamb.
Measure the middle of the rough opening of the swing side and make a small mark at the top. Now measure the middle of the pre-hung door and make a small mark. From the mark on the rough opening, make a mark on the hinge side exactly half of the new jamb width on the waall. This will tell you where the new door will be placed.
Place the new jamb into the opening, lining up the upper edge with your pencil mark. Shim as necessary on the bottom of the jamb to make sure the door will swing free when completed. Normally, 3/8" off of the subfloor is needed.
Take your level and plumb the hinge side, placing the level against the wall and against the door casing.
When you have it somewhat plumb, and the casing is on your mark on the wall, install a 6p nail in the upper hinge corner by your mark. Do not nail this all the way in yet.
Now plumb the jamb with the level. Nail next to the lower hinge another 6p nail...again not all the way in.
Now, on the lock side, adjust the casing up or down and left to right to make the gap the same all the way around the door. Again nail 6p nails not all the way in at the top and bottom.
Now swing the door to see if it clears the flooring. Now look on the other side to see if the outer slip jamb piece will fit properly.
If so, shut the door and install another 6p nail next to the middle hinge and near the lock. These can now be nailed down to within 1/8" of the material.
Install shims between the jamb and the rough opening to create a tight fit of the jambs. Install an 8p nail, leaving room for the slip jamb to slip into the groove later. Do this in the 6 places as before...next to the 3 hinges and on the lock side.
Now install the slip jamb and seat it on the wall. Nail 6p nails in the 6 places and 8p nails next to the previous 8p nails.
Now take the nail set and sink all the nails to just below the surface of the wood.

Hope this was some help.
Good luck!

How do I install a door, hang a door, install a French door, install an interior door or install a prehung door? These are the most frequently asked questions on the internet concerning this topic. The following article will give you advice as to what a high quality door installation entails.


Step #1
Determine what state of readiness you would like your doors to be in before ordering.

The first step in a door installation project is to determine what state of readiness you want your doors to be in. This important step will determine how difficult your door installation will be. Doors can be ordered a number of different ways. Doors are available as assembled/prehung, partially assembled/pre-hung, knocked down/pre-hung, un-machined slabs, fully machined slabs or partially machined slabs. They can also be unfinished or pre-finished.

The vast majority of doors sold today are sold as assembled/pre-hung unfinished. This may not be your best choice however. You will have to determine what state of completion you should buy your doors in based on what phases of door hanging and finishing you would like to complete yourself, what tools you have available, how you would like to apply the finish and whether your doors are going into new construction or into existing jambs.

Assembled/ pre-hung doors come with the jambs fastened together, the door stop applied to the jambs, the hinges installed to the jambs, lock prep completed and the door beveled and hung on the hinges. Sometimes the door casing is also applied to one side of the jambs or both sides in the case of split jambs but we will not concern ourselves with split jambs or door casing at this time.

Partially assembled/ pre-hung doors are usually exactly like assembled/ pre-hung doors with one exception. The door stops are shipped loose instead of applied.

Knocked down/ pre-hung doors means all of the machining and prep work has been done on the doors and the jambs just as with assembled/ prehung doors but the jambs are not fastened together, the hinges are not installed to the jambs, the door stop is not applied to the jambs and the doors are not hung on the hinges. It usually takes about 5 to 10 minutes to put together a knocked down door unit into an assembled pre-hung door unit ready to install in the rough opening.

Un-machined slabs are doors that do not have hinge prep, lock prep, bevel, jambs, hinges or stop.

Partially-machined slabs are doors that do not have jambs, hinges or stop but may have hinge prep, lock prep or bevel completed.

Fully-machined slabs are doors that do not have jambs, hinges or stop but do have hinge prep, lock prep and bevel.

Unfinished doors are raw wood without primer, paint, stain, sealer or varnish applied to them.

Pre-finished doors have primer, paint, stain, sealer and/or varnish already applied to them.
