French Door Replacement for NC Homes
Two operable panels with the classic architectural detail. The right door for traditional homes opening to a porch, deck, or sunroom — and for interior openings between living spaces.
Signs Your French Doors Need Replacing
The patterns that tell you it's time. None subtle once you're looking for them.
Spot one or two? Time to call. We'll come measure and tell you straight whether it's a fix or a full replacement — no pressure.
- Symptom
Astragal seal failed at the center
The vertical seal between the two operable panels is the most failure-prone joint on a French door. Drafts felt at the center mean the astragal seal has aged out.
- Symptom
Top or bottom seal of the passive panel gone
The non-active panel of a French door pair has top and bottom bolt locks that compress against the head and threshold. When those compress out of position, the seal fails.
- Symptom
Glass panels rattling in the panel frame
The divided-light glass setting has loosened. Glass panes will eventually crack in the rattling position — replace before that happens.
- Symptom
Astragal hardware loose at the passive panel
The center astragal hardware that joins the two operable panels has loosened. The doors close but the seal between them doesn't compress fully.
How We Install French Doors
French doors are two operable panels that have to meet perfectly at the center. The astragal seal pulls tight only when both panels stay square and the bolt locks engage cleanly at head and threshold.

SECURITY
Multi-Point + Astragal Bolts
French doors lock at multiple points: the active panel uses multi-point locking, and the passive panel secures with head and foot bolts that engage the head jamb and threshold via the center astragal.
- Multi-point lock on active
- Head + foot bolts on passive
- Solid astragal hardware
- Reinforced jamb hardware
WEATHER
Astragal Compression Seal
The vertical astragal seal between the two panels is the most failure-prone joint. We use lines with full-perimeter astragal seals plus head and threshold compression — when the bolt locks engage, the seal pulls tight all the way around.

- Head + threshold compression
- Triple-seal weatherstripping
- Sill flashing every opening
INSTALL
Panel Alignment + Bolt Tuning
French door installation focuses on panel alignment and bolt-lock geometry. The two panels have to meet perfectly at the center so the astragal seal pulls tight. We adjust hinges and bolt strike plates by-the-thou during install.

Material Choice for French Doors
French doors need panel geometry that stays square so the astragal seal pulls tight. Fiberglass is the standard; wood is the historic-restoration pick for divided-light authenticity.

What is the difference between French doors and hinged patio doors?
French doors are two operable panels with a center seal between them — typically opening in the same direction. Hinged patio doors are a single swing-out unit, sometimes paired as double. French doors give you a wider unobstructed opening when both panels are open. Both work indoor or outdoor depending on the spec.
