Doors Are Measured, Not Bought Off a Shelf
Fireplace openings are rarely standard, and a door that does not seal properly is worse than no door at all: it looks wrong and it lets conditioned air straight up the chimney. Custom doors are built to the opening, which is why this is a conversation with measurements rather than a box off a shelf.
A well-fitted door controls airflow and cuts the heat loss a masonry fireplace otherwise leaks all winter. Gas logs solve a different problem, giving the look of a wood fire without hauling, storing or cleaning up after one. We carry both, and we will tell you which one your fireplace actually needs.
