Key takeaways
- Some problems — a loose strike plate, a worn sweep — are simple repairs.
- Rot in the frame, failed insulated glass and water at the threshold usually mean replacement.
- Older doors often fall short of today's security and design-pressure standards.
- A good installer will tell you honestly when a repair is enough.
Doors rarely fail all at once. They fade, stick, leak and rattle a little more every summer until one day you realize you are fighting the front door or the lanai slider every time you use it. Here are the signs we see most often in Central Florida — and how to tell whether you need a repair or a replacement.
1. You can feel drafts or see daylight
Stand inside on a sunny afternoon with the lights off. Light around the edges means air, humidity and bugs are getting in too. Repair if the weatherstripping or sweep is simply worn. Replace if the door is warped, the frame is out of square, or new weatherstripping cannot close the gaps.
2. Water gets in after storms
Wet floors, stained baseboards or soft flooring near a door after a storm are serious signs. They usually point to a failed sill, missing sill pan or missing flashing. Because the damage is often hidden in the subfloor and framing, replacement with a properly flashed, sill-panned installation is usually the fix.
3. The door sticks, drags or won’t latch
Swelling, sagging hinges and settling can all cause sticking. Repair if adjusting the hinges and strike solves it. Replace if the slab is warped or swollen, the frame has moved, or the problem comes back every summer.
4. Your slider is hard to open
Sliding doors that take two hands usually have worn rollers, a pitted track or a bent frame. New rollers can help a newer door, but on an older aluminum slider with a worn track, replacement usually costs less over time than repeated repairs.
5. The glass is foggy between the panes
Condensation or haze between the glass panes means the insulated glass seal has failed. The glass no longer insulates well, and it will not clear up. On some doors the glass unit can be replaced; on many older doors — and most sliders — replacing the door makes more sense.
6. Rot, rust, cracks or delamination
- Rot: Soft wood at the bottom of the jamb or brickmould is common in Florida. Probe it with a screwdriver.
- Rust: Steel doors rust from the bottom edge when the finish is damaged.
- Cracks and delamination: Skins separating from the core mean the door is failing.
Small, isolated rot in trim can sometimes be repaired. Rot in the frame or sill usually means replacing the entire entry system.
7. You don’t feel secure
Short strike screws, thin slabs, flimsy slider latches and old, easily defeated locks are common on original builder doors. A new entry system with a reinforced frame, long screws and a multipoint or high-grade deadbolt is a major upgrade — and an impact-rated door adds laminated glass that is very hard to break.
8. Rising bills, noise or an HOA letter
An old door can make a foyer or family room noticeably hotter and noisier. And sometimes the reason is simpler: the door looks tired, or the HOA has asked you to replace it.
