Prehung Bifold closet doors

Bifold Doors

WonderHowTo 2302 4 years ago

Dear NH,
I want to install bi-fold closet doors in my bedrooms where sliding doors existed previously. The problem is that the openings are 46", which is too small for the standard 48" bifold doors. I want to use the 6-panel Masonite type doors as I've used on the bedroom entrance doors. I tried ripping one set of doors and they bowed. Any /*suggestions, please? (My daughter has requested doors as her only birthday present, so I'm under the gun by daughter and wife!)

I can give you a number of options... choose the one that best suits your needs and abilities.

One would be to use solid doors instead of hollow doors. 6-panel molded doors are available with a solid core allowing you to cut a little more from each edge without having the doors weaken. Just be sure to cut the same amount from all 4 vertical edges so the doors look balanced. Most prehung bifold door "sets" come with hollow doors, so you will have to order raw solid doors and purchase the bifold hardware separately.

Another option would be to use three doors instead of two... you would have to use standard hinges on the "outside" door since the standard bifold hinges have a support tab that is unattractive on the outside of the door. Then you need to do less trimming per door edge.

In your letter, you mentioned that the doors "bowed" after trimming. This is because you cut off most of the supporting wood along the edges. This wood can be replaced by cutting and then installing a wood strip along the length of the door to reinforce the edge. The new strip is simply glued in place and clamped till dry... usually 24 hours depending on your choice of adhesive. If you want to add a few nails or screws, do it from the back of the door so they won't show.

Yeah- generally speaking, they are really only

You simply don't have *any* room to swing a standard door or to operate a bifold, or the opening is too small for a bypass unit to work and there's no room for the other options.
In the case of a 6' opening, you would need an additional 36" (door width)+ 4" (for the frame) on each side, or 112" of total free wall space to start with to install pocket doors.

    I have cabinets in my kitchen that are painted.......i want to go oak face frame and doors...............can i pull off the existing face frame, and replace with an oak question is......whats the best way to build the frame......dowels?

    • The face frames may be a beotch to replace; they were built on the cabinet boxes, or glued to them. Just depends on the construction. The best way is to use pocket screws. There is an angled hole (pocket) drilled into th …e fancy machine).

      Otherwise, you just apply the boards individually to the cabinet box and pin the edge that hangs down with a finish nail (not the best method, but it's done on built in shelves everyday).
