You might not notice it right away, but the trim around your doorways has a big job to do. It’s called an ‘interior door casing,’ and it’s a key piece of your home design. It's not just there to look good–it also helps your doorways function better.

Interior Door Casing Explained

Door casings are like picture frames for your doors. They are the moldings, or trims, that go around the door opening from the floor to the top of the door, over the top, and back down the other side.

Interior door casings serve a dual purpose–they are functional and decorative. On the functional side, door casings help cover up the joints between the door frames and the wall. They also add an extra layer of insulation, preventing drafts and helping to keep your home comfortable. 

On the decorative side, casings provide an opportunity to enhance the aesthetic appeal of your home and make your recently purchased interior doors in Las Vegas look complete.

What Interior Door Casings Can Do For You

Interior door casings can make your doorways look better in a number of ways:

Boost Aesthetic Appeal

Have you ever noticed how a nice frame can make a painting look even better? This is what door casings can do for your doorways, but the trick is choosing the right one. Different styles of homes call for different styles of door casings. Here are a few pointers to consider if you are in the market for door casings:

  • Colonial and Georgian-style homes often feature classic design elements. A door casing with fluted sides and a decorative crown could be a great match for these houses.
  • If your home has a more modern and minimalist aesthetic, a flat and clean-lined contemporary casing could be a fantastic choice.
  • For those homes that have a cozy feel to them, a craftsman door casing with a thick top edge and a simple design might be the perfect addition. 
  • If you’ve got a country-style home, a rustic-looking door casing can create a warm feeling that fits right in with the rest of your home.

Increase Property Value

Believe it or not, small details like door casings can make a big difference when it comes to the value of your property. It's one of those features that, when done well, can really add to the overall appeal of your home, and this added appeal can translate into a higher property value.

In this regard, high-quality door casings can make your entire home seem more high-end. They can also give the impression that your home is well-built and well-maintained, which can help you fetch a premium price when you’re ready to sell.

Provide a Finished Look

Door casings provide a neat transition between different materials and surfaces. Without them, you'd see the rough edges where your drywall meets your door jamb, which can be unsightly. However, with casings, these transitions are hidden, making everything look more seamless and put together. 

Materials Used for Door Casings

Door casings can be made from a variety of materials, each offering different benefits and aesthetic qualities. Here are two of the most common materials:


Wood is a classic, beloved material that is usually a good choice. Many people choose wood for their door casings because it lasts a long time, and it comes in a variety of styles and price points. 

Pine, oak, mahogany, and other types of wood used for door casings each have their own special color and pattern. Remember, though, that wood can be pricey, costing anywhere between $0.75 to $6 per linear foot. Wood also needs some tender loving care to keep it looking its best.

Medium Density Fiberboard (MDF)

MDF is less expensive than natural wood but still provides a similar look. It's made from wood fibers combined with a resin binder for a product that's easy to cut and shape. MDF is resistant to warping and shrinking, making it a durable option. That said, it's not as strong as solid wood and doesn’t hold up as well if there is high humidity or moisture. 

The Takeaway

Door casings are not just for curb appeal–they also make your doors function better and keep your home comfortable. So, whether you choose wood or MDF, the right casing can make a difference to your home!
