Benefits of Bi-Fold Doors

You have many patio door options to choose from today, but bi-fold doors could be right for you if these are the benefits you’re hoping to enjoy:

Luxurious Appearance

When you open your bi-fold patio doors, the comforts of indoor living and the beauty of your outdoor space merge into one. Bi-fold doors allow you to maximize an opening, whether modest or expansive. This provides an impressive appearance when the doors are open. Still, the wall of glass offers a stunning view of the vistas beyond, even when they’re closed.


Bi-fold doors are available in various configurations to accommodate whatever size opening you have to work with. Your investment creates a custom look that impresses guests and neighbors alike. Because they’re so versatile, you’ll see bi-fold doors everywhere, from homes to restaurants to car dealerships in Annapolis, Bethesda, Alexandria, and across the DC area. It’s important to work closely with a door installer to produce the results you’re looking for.

A Maximized Door Opening

The patio door option most similar to a bi-fold door is a lift and slide door. While they share many benefits, one advantage bi-fold doors have over lift and slide doors is their maximized opening. When fully open, bi-fold doors sit perpendicular to the wall while lift and slide doors remain parallel. You can overcome this by pocketing the sliding door, but this increases installation costs. No such compromises are required with bi-fold doors.

Durability and A Long Life Span

Bi-fold doors are available in all-wood or aluminum-clad, which is extruded aluminum on the exterior and wood on the interior. Whatever material you choose, bi-fold doors are designed to withstand exposure to the elements and continue to work flawlessly even after years of heavy use. This means your investment stands the test of time, adding to your home’s beauty and functionality for years to come.

Some of the frequently asked questions we receive about bi-fold patio doors in DC, Maryland, and Virginia are:

Can I install my own bi-fold patio doors?

This is not recommended. In addition to structural damage risks, you could get into some dangerous electrical wiring issues. Additionally, if a fire or other damage results from a DIY [do-it-yourself] installation, your insurance company can refuse coverage.

If you’re thinking about installing your own bi-fold doors, keep in mind that no home’s wall is perfect, especially if it has aged. Box-store bi-fold doors may not fit the way they should and leave gaps that cause energy loss and pose security risks.

After your installation, if the doors don’t operate correctly, you’ll wind up pushing, pulling, and forcing them, which will eventually damage them, and you’ll need replacements. By then, you’ll have realized bi-fold patio doors need to be professionally ordered and installed.

Do bi-fold doors open inwards or outwards?

They can open either way; it’s your choice.

Do bi-fold patio doors need a track?

They need two tracks; top and bottom. They can be engineered in a lot of ways, but this is the best way all-around.

  • The tracks balance the weight of the doors at the bottom.
  • Top-hung bi-fold doors need a track to support the weight on top. (Top-hung bi-fold doors need strong structural support.)
