Learning on the Job: Custom Architrave Build for a Front Door

No matter how long you’ve been in the trade, there’s always something new to learn—and this custom front door project reminded me of that in the best way.

The challenge here was replicating a unique interior header trim piece, also known as an architrave, to match the client’s existing trim style. It wasn’t just about copying—it was about complementing the new door while respecting the original design language of the home.

The door itself was a woodgrain fiberglass door, chosen for its durability, low maintenance, and ability to mimic the warmth of natural wood. That meant the surrounding trim also had to rise to the occasion—both in craftsmanship and in finish.

To a seasoned finish carpenter, this might sound routine. But for me, it was uncharted territory. Most of the interior trim work I do uses standard casing profiles, up to about 4.5 inches wide. At this point, I have 30 or 40 trim styles at my disposal from local lumber yards. But when it comes to decorative header trims, I’ve mostly worked with pre-milled options.

This time, we needed to build a custom architrave from scratch—and I’m really glad we did.

Matching, Enhancing, and Building Trim

The goal was to recreate the original profile while scaling it up slightly to give the new entry door system a stronger, more grounded presence. I broke the existing profile down into its individual elements, sourced the matching trim components, and layered them to recreate the look—only bigger and bolder.

The final piece was stained to match the tone of the woodgrain fiberglass door, and the overall result was a perfect balance of tradition and enhancement. It looked like it belonged in the home, but also subtly elevated the entire entryway.

Why It Matters

This job pushed me out of my usual toolkit—and that’s exactly why I value it so much. It showed me that even small architectural details, like a trim piece above a door, can have a huge visual impact. And it reminded me that growth often comes from the jobs that challenge your assumptions, not the ones that run on autopilot.

It also gave me the confidence to tackle more complex custom trim assemblies, and I’ve already got a follow-up post planned for next week featuring one of the most intricate builds I’ve done to date.
