How to Install a Threshold for a Deep Jamb in a Brick House (Cold Climate, Canada)

I recently replaced the front door of my old brick house in Canada (cold climate). The new door is installed, but the jamb is very deep—there’s still a 6-inch gap from the exterior edge of the brick to the new threshold. I need advice on how to cover the remaining open areas, especially the threshold. Context: • The house is brick, and the jamb depth leaves a 6-inch gap from the exterior brick edge to the new door’s threshold • For the vertical sides, I plan to use moulding attached to the existing black jamb boards. I’ll add more moulding at the brick edge to hide the color difference. • The threshold is my main concern. There’s a half-inch height difference between the new door’s metal threshold and a black piece of wood currently acting as a temporary surface (I can remove this wood if needed, as shown in the photos). The area has exposed foam insulation My questions: What’s the best way to install a new threshold to cover this 6-inch gap and the half-inch height difference? What materials should I use? (e.g., plywood, aluminum, something else?) Any tips for ensuring it’s weatherproof and durable in a cold, Canadian climate? I’d appreciate detailed steps or product recommendations if you have them. Thanks! submitted by /u/DoYaFeelLuckyPunk [link] [comments]

My questions:

What’s the best way to install a new threshold to cover this 6-inch gap and the half-inch height difference?
1. What materials should I use? (e.g., plywood, aluminum, something else?)
2. Any tips for ensuring it’s weatherproof and durable in a cold, Canadian climate?

I’d appreciate detailed steps or product recommendations if you have them. Thanks!
