Are you searching for interior door and window jamb trim and moulding? If so, you’ve come to the right place. Doors and windows are made up of many different components. To a nonprofessional, these components are easy to confuse with one another.

So, before we jump into the various ins and outs of interior window and door jambs, let’s take a moment to discuss what they are and why they’re essential. Here’s everything you need to know about window and door jamb trim and moulding.

What Are Interior Door and Window Jambs?


Window and door jamb is visible both on windows and doors when they are closed. It provides structure to the door and window units and on doors is what the hinges are connected to. It is also what the casing is connected to to close the gap from the wall to window or door.

Why Are They Important?

Door jamb moulding and window jamb trim serve many vital purposes, but their primary function is to keep everything together. If you didn’t have a window jamb in your window frame or door jamb in your door frame, then they would easily fall out of alignment.

Without this critical structural element, doors and windows wouldn’t be aligned appropriately within their frames, making them almost impossible to open and close. Door and window jambs make everything run smoothly.

What’s the Difference Between a Jamb and Casing?

When you look at door and window casings, you might confuse them with jamb trim and moulding. If that’s the case, you’re not alone, but there is a difference.

As we already discussed, a jamb is a vertical piece of trim or moulding that is installed along the door or window frame to hold everything together. Conversely, a door or window casing is a decorative element that covers the frame, and provides a clean overall aesthetic.

The Average Cost of Door and Window Jambs

The average cost of a door jamb or window jamb depends on the materials used, the size of the windows or doors, the brand, and the installation costs. If you’re installing them yourself, you can save a bit on the overall cost. However, before you commit to any price, research and contact a professional who can advise you on what kind of cost you should expect for your specific project.

How Often Do Window and Door Jamb Trim and Moulding Need to be Cleaned, Repaired, or Replaced?

If you purchase high-quality jamb moulding for your home, it should have the same lifespan as the doorframe or window frame – maybe even longer! Door frames can last up to 30 years with bi-annual maintenance, and window frames can last up to 50 years with proper care. Of course, that life expectancy requires regular cleaning and repairs when necessary. You should clean your door frames and window frames at least once per month and make repairs as necessary.

Most Common Materials for Window and Door Jamb Trim and Moulding

Window and door jamb trim and moulding come in various materials. Choosing which material is best depends on several factors, including longevity, durability, cost, and style. Here are three different door and window jamb moulding and trim materials you can choose from:

1. Wood

You can find door and window jambs made from various kinds of wood, including oak, pine, birch, poplar, and more. These materials range in density, strength, and design. If you’re looking for a high-quality, luxury material for your door and window jambs, you can’t go wrong with wood!

2. MDF

MDF, otherwise known as medium-density fiberboard, is a type of engineered wood that comes in an array of colors and styles. It’s typically priced lower than natural wood and requires less maintenance.

3. Vinyl

Vinyl is one of the most well-known materials used by home improvement professionals and contractors. It’s incredibly cost-effective, durable, and low maintenance, which makes it a perfect material option for projects with a tighter budget.
