If you’ve ever noticed the trim wrapped around the outside of a door frame and wondered what it’s called, you’re not the only one.
Brickmold on a door is one of those details most owners walk past every day without giving it a second thought.
But it does more than you might expect. In this guide, we’ll break down exactly what it is, what it does, and why it matters more than you think.
What Is Brickmold on a Door?
Brickmold is the exterior trim that wraps around the outside of a door frame. It covers the gap between the door frame and your home’s siding or exterior wall, giving it a clean, finished look.
The name comes from its original use alongside brick siding, but it stuck even as materials changed. You’ll also see it spelled brickmould. While brickmold appears on windows, too, this post focuses on doors.
Brickmold vs. Door Casing
A door uses different trims inside and outside, each with a specific role and placement. Understanding the distinction helps avoid confusion during installation or renovation.
| FEATURE | BRICKMOLD | DOOR CASING |
|---|---|---|
| Location | Exterior of the home | Interior of the home |
| Purpose | Seals and frames against the weather | Covers gaps for a finished look |
| Analogy | Outdoor jacket | Indoor outfit |
What Does Brickmold Look Like?
Brickmold runs along the top and both sides of your door frame, forming an upside-down U shape. It’s typically about 2 inches wide with a slightly curved outer face, though profiles vary by style.
Colonial brickmold features decorative curves, making it a great fit for traditional homes.
Modern brickmold uses clean, straight lines that suit minimalist and contemporary styles. It can also be smooth or detailed depending on your home’s architecture.
What Is Brickmold Made Of?
Brickmold comes in several materials, each with different trade-offs in durability, maintenance, and cost. The right choice depends on your climate, budget, and the finish you’re after.
| MATERIAL | PROS | CONS |
|---|---|---|
| Wood | Classic look, paintable or stainable | Can rot, requires regular maintenance |
| PVC / Vinyl | Rot-resistant, low maintenance, affordable | May look less premium than wood |
| Composite | Durable, rot-resistant, paintable | Higher upfront cost |
| Aluminum | Very durable, modern appearance | Can dent, conducts cold |
What Does Brickmold Do?
Brickmold does more than just look good; it plays several important roles in protecting your door and home. Here are the key functions:
- Seals the Gap: Covers the space between the door frame and exterior wall, blocking water and air infiltration.
- Weather Protection: Shields the door frame from rain, wind, and humidity damage.
- Pest Barrier: Closes off entry points for insects and other pests.
- Aesthetic Appeal: Creates a clean, finished look that boosts curb appeal.
- Installation Aid: Acts as a buffer during pre-hung door installation, making it easier to plumb and level the unit.
Benefits of Brickmold on a Door
Brickmold isn’t just decorative; it delivers real, practical value for your home. Here are the five key benefits:
- Extended Lifespan: Protects the door frame from rot, moisture, and weather damage, helping it last longer.
- Improved Curb Appeal: Gives your entryway a clean, polished look that enhances your home’s exterior.
- Enhanced Security: Reinforces the door frame, adding an extra layer of structural strength.
- Better Energy Efficiency: Reduces drafts and air leakage, helping to lower heating and cooling costs.
- Easier Installation: Simplifies the process of fitting and leveling pre-hung door units.
Drawbacks of Brickmold
Brickmold has plenty of benefits, but it’s worth knowing the downsides before making a decision. Here are five potential drawbacks:
- Can Look Bulky: On modern or minimalist homes, brickmold may feel visually heavy or out of place.
- Wood Requires Maintenance: Wood brickmold is prone to rot and needs regular painting or sealing to stay in good shape.
- Higher Installation Cost: More complex and costly to install compared to no-brickmold door options.
- Compatibility Issues: Not always a good fit for wall openings that are out of square or uneven.
- May Need Removal: If the wall isn’t level, the brickmold may need to be removed and reinstalled during the process.
Brickmold Door vs. No Brickmold Door
This comparison helps clarify which option fits your project, especially if you’re balancing style, cost, and installation needs.
| FEATURE / SCENARIO | BRICKMOLD DOOR | NO BRICKMOLD DOOR |
|---|---|---|
| Overall Look | Traditional, more detailed | Sleeker, cleaner, more modern |
| Exterior Finish | Built-in trim creates a framed appearance | Flat, minimal edge ready for custom trim |
| Best For Home Style | Classic, colonial, traditional homes | Contemporary, modern, minimalist homes |
| Installation Use Case | Ideal for replacements matching existing trim | Better for new construction or custom design plans |
| Weather Protection | Adds an extra sealing layer for rain and humidity | Relies on separate trim and sealing |
| Budget Consideration | Slightly higher upfront (includes trim) | Lower initial cost, but trim may be added later |
Note: Skip brickmold for new builds with custom trim, modern minimalist designs, or tight budgets. No-brickmold doors offer more flexibility and a cleaner, simpler finish.
Does Your Door Come With Brickmold
Most pre-hung door units come with brickmold already attached, so installation is straightforward. You can also buy it separately as individual lengths of moulding if needed.
If you’re replacing an existing door, take note of your current brickmold profile before shopping. You’ll want to match it as closely as possible to keep a consistent look on your home’s exterior.
Whenever you’re uncertain, just take a sample to your local hardware store; it’s always a helpful step!
Brickmold Maintenance Tips
Staying on top of brickmold maintenance can save you from costly repairs down the road. Here are five simple tips to keep it in good shape:
- Inspect Regularly: Check for cracks, gaps, or soft spots; these are early signs of rot or weather damage.
- Caulk Annually: Seal any gaps between the brickmold and siding every year to keep water and air out.
- Repaint Wood Brickmold: Freshen up the paint every few years to protect it from moisture and UV damage.
- Replace Rotted Wood with PVC: If you find rot, swap out the wood brickmold for PVC to prevent the problem from spreading.
- Best Tip: Choose PVC or composite from the start to minimize maintenance for years to come.
