🔥 Step 1: Identify Your Fireplace Type

Start by confirming whether you have a masonry or a prefabricated (factory-built) fireplace — this determines door compatibility and safety.

Masonry Fireplace
  • Built from brick/stone; real brick firebox.
  • Usually has a full masonry chimney.
  • Supports heavy-duty doors; ceramic glass is an option.
Prefab (Zero-Clearance)
  • Factory-built metal firebox with a metal chimney pipe.
  • Often has a manufacturer label/tag behind louvers or inside the frame.
  • Typically uses tempered glass doors.
Tip: If you see a metal ID tag or a metal chimney pipe, you have a prefab (factory-built) fireplace. If the firebox is made of brick and the chimney is full masonry, you have a masonry fireplace.
📐 Step 2: Fireplace Shape
  • Rectangular: Most common and easiest to fit (often supports stock sizes).
  • Arched: Usually needs a template/tracing for a perfect custom fit.
  • Multi-Sided: Corner, see-through, and peninsula fireplaces typically require custom engineered doors.

📏 Step 3: Measure Correctly
  1. Measure width at the top, middle, and bottom — use the smallest number.
  2. Measure height on both sides (and the center if arched) — use the shortest number.
  3. For masonry fireplaces, locate the lintel bar and measure to the bottom of the lintel.
  4. Select your size: add Width + Height to find your category. Example: 40W + 23H = 63 (choose Medium).
  5. Quick square-check: measure diagonals corner-to-corner. If they differ, your opening is out of square — we’ll size to cover properly.

⚒️ Step 4: Installation Fit
  • Overlap (Face-Mount): Frame overlaps the opening; hides gaps; ideal for masonry; forgiving on imperfect openings.
  • Inside Fit (Flush-Mount): Frame sits inside the opening; sleek look; requires more accurate measurements.
  • Special Case: Hole-in-wall (no hearth) usually needs a 4-sided overlap frame with a bottom piece.

Cabinet Doors

Two panels that swing open left/right. Clean look and a wide opening when fully open.

Bi-Fold Doors

Panels fold back to the sides, saving space in front of the fireplace. Great when you want more clearance.

🪟 Step 6: Glass, Materials & Finish
  • Glass: Tempered (most common) or Ceramic (for burning with doors closed and keeping more heat inside the opening).
  • Frame Material: Steel (heavier, premium) or Aluminum (lighter, budget-friendly).
  • Finishes: Powder-coat matte black, bronze, graphite, or premium plated/brushed metals.
  • Glass Looks: Clear view; gray/bronze tint to reduce glare; mirrored/black to conceal the firebox.
🧵 Step 7: Mesh & Accessories
  • Mesh Curtain: Slides on a rod; spark protection when glass is open.
  • Mesh Doors (Gate): Hinged steel mesh panels; premium look and easy operation.
  • Hardware: Handle styles, magnetic catches, optional child-safe locks.
If you burn wood with the glass open, use a mesh barrier for safety and ember control.
🛒 Step 8: Order & Installation
  1. Choose custom (perfect fit, more options) or stock (faster, budget-friendly).
  2. Upload photos for expert review so we can confirm fit and mounting.
  3. Verify your smallest width and shortest height measurements.
  4. Expect a few weeks for custom production; stock ships faster.
  5. Install with included hardware, or hire a pro for heavy/complex sets.
