Pre Hanging Information

A pre-hung door is a door that is already hanging in its own frame. It's an all-in-one package that ensures the smoothest possible installation of your door.

If your scenario is one of the following:
  • No existing door frame
  • The existing door frame is damaged
  • New construction

We suggest you get your door with the pre-hanging option!

Note:

When installing an exterior door, unless you are a pro, it's extremely hard to tight-fit an exterior slab door.
Pre-hung doors come with weather-stripping and are tight-fitting off the shelf.
A tight-fit door will save you on your energy bill.

A slab door is just a rectangular slab of wood. It has no hinges or hardware. It is up to you to attach it to the frame.

all pre-hung door units are preassembled at manufacturer and shipped with the frame dissasembled (with the exception of single door units which will arrived assembeled) to ensure no damage to the frame or doors during shipping. The crate will arrive at its destination with the door/glass assembled but the frame will not be assembled. Reassembly is simple and requires only a screwdriver. A packing list will be included inside the crate so the customer can check the accuracy of all components.

What to consider when buying a pre-hung door?

  1. Make sure the new door frame will fit the rough opening. With most doors we offer the option to trim the door if needed, call us for details.
  2. Jamb width refers to the thickness of the wall. The jamb needs to cover the stud plus any wall application such as dry wall or sidings.
  3. Know your door handing (swing). See diagram below with illustrations of the various options.
  4. Select casing that matches the door and home style.
  5. Review finishes of the pre-hung components. Select finish colors for the hinges, sill and door shoe.
  6. For staining applications we recommend matching the jamb wood species to the door.

How to accurately measure rough opening

  • Measure the widths between the studs of the entryway 3 times; from the highest points of the opening, the center points, and the lowest points. Record the smallest width of the 3 measurements.
  • Measure the height (from the floor to the highest point of the opening) on both sides and record the smallest measurement of the 2.

Rough opening recommendations

Getting the rough opening size right the first time, will save you from frustration, when installing your doors. Framing and calculating rough opening sizes are really quite simple.
Tip:
Not all rough openings are completely plumb and square. Leaving extra space allows you to perfectly plumb, level and square your door installation.
