Signs your French doors need repair.
French doors have two panels that need to work together perfectly. When one panel drops, the hardware wears out, or the seals break down, the whole system stops working right. Here are the most common problems we fix.
Doors Won't Close Together
The panels don't meet in the middle. One sits higher than the other, leaving a visible gap and making the lock impossible to engage.
Gap Between Panels
You can see daylight or feel air between the two closed doors. The astragal or weatherstripping has failed.
Astragal Broken or Damaged
The vertical strip where the doors meet is cracked, bent, or missing. This kills the seal and makes locking difficult.
Hinges Sagging
The door panel has dropped and scrapes the threshold or frame. The top hinge screws have pulled out of the wood.
Lock Won't Engage
The latch or bolt won't reach the strike plate because the panels have shifted out of alignment with each other.
Drafts Between Doors
Cold or hot air blows through the gap where the doors meet. Your energy bill goes up and the room never feels comfortable.
Why French doors fall out of alignment
French doors are heavier than standard interior doors, and all that weight hangs on just a few hinges. Over time, the screws loosen, the hinge mortises compress, and the door slowly drops. Florida's humidity makes it worse because wood frames expand and contract with the seasons. The result is panels that don't line up, locks that won't catch, and gaps that let air and insects in. The good news is that most alignment problems are fixable without replacing the doors. We tighten or replace the hinges, use longer screws to grab solid wood, and shim the frame if needed.
How we repair French doors.
Every French door repair starts with figuring out exactly what went wrong. We don't guess. We check every component so we fix the root cause, not just the symptom.
Full Inspection
We check the hinges, astragal, weatherstripping, lock hardware, frame, and threshold. We identify every issue before we pick up a tool.
Fix the Hinges
If the door is sagging, we tighten or replace the hinges, use longer screws, and shim if needed. This is the foundation of the repair.
Repair Hardware and Seals
We replace the astragal if it is damaged, install new weatherstripping, and repair or replace the lock hardware so the doors seal tight.
Test and Adjust
We open and close both panels multiple times, check the lock engagement from both sides, and confirm there are no gaps or drafts. You will feel the difference.
Astragal repair and replacement
The astragal is the part most homeowners don't know about until it breaks. It is the vertical strip on the edge of one French door panel that overlaps the other panel when closed. The astragal creates the weather seal, provides security where the doors meet, and helps the lock engage properly. When it cracks, warps, or breaks off, you get drafts, water leaks, and a lock that won't hold. We carry common astragal profiles and can replace most of them in 30 to 45 minutes. For specialty sizes from brands like Andersen or Marvin, we can source the exact part in 24 to 48 hours.
This is not the same as French door conversion
People sometimes confuse French door repair with French door conversion. They are completely different services. French door conversion is when you remove a sliding glass door and install a new French door system in its place. French door repair is what we are talking about on this page: fixing problems with the French doors you already have. If your existing French doors just need new hinges, a seal replacement, or a hardware fix, you don't need a full conversion. You need a repair, and that is what we do. Call (772) 207-4146 and we will figure out exactly what your doors need.
