The Door That Dresses Up a Room
Some upgrades earn their keep in utility bills; French doors earn theirs the moment you see the room. A pair of glass panels swinging open to the patio changes how a dining room, primary suite, or home office feels — more light, more ceremony, more connection to the yard — in a way a slider, whatever its virtues, never quite matches. It's the door people choose with their eyes, and the engineering has caught up to the romance.
Hinged, Sliding, In or Out
Classic hinged pairs are the full experience: both panels swinging wide for parties and furniture days, one active panel for daily traffic. They want swing clearance, which generous rooms have and galley layouts don't.
Sliding French doors put French styling — wider stiles and rails, divided-lite options — on sliding hardware: the look without the floor space. This hybrid is our most-quoted French style in newer subdivision homes.
Outswing units flip the swing to the patio side, freeing the interior entirely — with a quiet bonus for our climate: wind pressing on an outswing door presses it into its seals. On exposed west and south walls that detail earns its choice.
The Efficiency Surprise
Buyers assume all that glass and a center meeting point cost efficiency; the specs say otherwise. Hinged panels compress their weatherstripping when latched — multi-point hardware pulling top, middle, and bottom tight — which typically outperforms a slider's brush seals on air infiltration. Add Low-E insulated (and code-required tempered) glass, and quality French doors sit comfortably inside zone 5B targets. On unshaded exposures we spec the low-SHGC coating, same rule as any big glass in this valley.
Built Right at the Threshold
A French pair lives or dies at its meeting stile and threshold — panels must meet true or the seals gap and the astragal wears. Our carpenters (Wood Windows employees, every job, since 1980) set frames dead plumb, rebuild pan flashing under every threshold, and tune the multi-point hardware so both panels latch with a fingertip. Clad-wood pairs from Andersen and Marvin, fiberglass systems, and vinyl sliding-French styles are all in the book — with real examples at the Garden City showroom.
For traditional and historic homes, divided-lite patterns deserve a moment's thought: true or simulated divided lites in a 6-, 10-, or 15-lite layout change the door's character completely, and matching them to your windows' grid pattern is the detail that makes the whole elevation read as designed rather than assembled. We bring the pattern samples to the measure.

Frequently Asked Questions
What do French doors cost installed?
Vinyl sliding-French styles start around $2,500–$3,800 installed; hinged fiberglass and clad-wood pairs run $3,500–$6,500; premium wood and custom-divided-lite systems climb from there. Numbers include tear-out, threshold flashing, hardware, and finish trim.
Are French doors less efficient than sliders?
Typically the opposite. Hinged French panels close against compression weatherstripping — squeezing the seal like a refrigerator door — which usually beats a slider's brush seals on air-tightness. With Low-E insulated glass, quality French doors post strong NFRC numbers for zone 5B.
Do both panels of a French door have to open?
No — the most popular configuration is one active panel with a passive mate that opens for furniture and gatherings. Fixed-panel and slider-French hybrids exist too. Choosing active/passive layout by how you actually live is part of the measure conversation.
Can a French door replace my sliding door in the same opening?
Usually yes — standard slider widths (5', 6', 8') convert cleanly to French pairs, often without structural work. Swing clearance is the real question: hinged panels need floor space a slider doesn't. Tight rooms sometimes land on outswing units or a sliding-French style that gives the look without the swing.
