The cost to install french doors in Cary ranges from $1,530 to $6,100, with most homeowners paying around $3,560. Your actual cost depends on several factors specific to your home and the Raleigh-Cary market.
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.
The South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
Budget $52–$210 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Standard double-pane windows perform well in mild climates. Focus budget on quality frames and hardware rather than extreme weather ratings.

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.
