Steel is cheapest ($600–$1,500). Fiberglass is mid-range and low-maintenance ($1,000–$3,000). Solid wood is premium ($1,500–$5,000+).
Exterior French doors need weatherstripping, a threshold, and security hardware, adding $300–$800 over interior installations.
If the opening needs to be widened or created in a load-bearing wall, a structural header adds $500–$2,000 in framing and engineering costs.
Adding sidelight windows or a transom above the doors increases cost but dramatically enhances the appearance and natural light.
Basic hardware costs $50–$100. Premium locksets, handles, and multi-point locking systems for exterior doors run $200–$600.
Mountain region costs are rising with population growth. High altitude and variable weather can affect project timelines. Skilled trade labor is in high demand in booming markets.
Budget $54–$216 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.

Modern French doors with Low-E glass and proper weatherstripping are reasonably energy-efficient, though they allow more heat transfer than solid walls. For the best energy performance, choose double-pane or triple-pane glass and ensure the door is properly sealed. The glass area means they'll never insulate as well as a solid wall.
French doors offer a more traditional look, swing fully open for wide access, and seal more tightly. Sliding doors save space (no swing radius), provide wider glass panels, and cost less. Choose based on your aesthetic preference, available wall space, and whether you need maximum opening width.
