Door won’t latch
A door that won't latch is usually a sagging hinge or a misaligned strike plate, not a sign of a serious structural problem — both are quick, inexpensive fixes on most Casselberry homes.
What is most likely wrong
| # | Cause | How common | What it looks like |
|---|---|---|---|
| 1 | Sagging hinge (loose or stripped screws) | Very common | The door drops slightly at the latch side over time; tightening or replacing hinge screws often fixes it in minutes. |
| 2 | Strike plate misalignment | Common | The latch bolt no longer lines up with the strike plate hole, often from minor seasonal movement. |
| 3 | Humidity swelling | Common in Florida | The door itself swells slightly in humid months and shrinks in dry ones, changing how it sits in the frame. |
| 4 | Frame shift from house settling | Less common | Paired with other signs (see our drywall crack page) rather than appearing alone. |
What you can safely check yourself
- Close the door slowly and watch where the latch bolt meets the strike plate — note if it is high, low, or off to one side.
- Tighten all hinge screws; if a screw spins without biting, that hinge is the likely cause.
- Check for a visible gap that is uneven top-to-bottom, which points to a sagging hinge rather than the latch itself.
If any of this involves opening an electrical panel, running new wiring, cutting into a gas or water line, or working higher than a stepladder safely reaches, stop and call a licensed tradesperson — that is not handyman-scope work, regardless of how small the fix looks.
Why this happens in this housing stock
Interior doors on Casselberry’s 1970s–80s housing stock are very often original hollow-core doors on their original hinges — forty-plus years of use is exactly when hinge screws strip out of softwood jambs. It is one of the fastest, cheapest fixes we do.
What the fix typically costs
| Job | Researched range | What drives it |
|---|---|---|
| Lock / hardware repair or install | $85–$171 | Hardware grade and re-mortising. |
| Interior door replacement | $150–$400 | If the door itself, not just hardware, needs replacing. |
These are researched third-party market ranges, not this business’s pricing — see the sources at the bottom of the page. Add the Casselberry permit fee on top of any job that needs one.

Send a photo, the approximate age of the house, and what you already checked. That is usually enough to know whether it is a handyman fix or needs a licensed trade.
