Somewhere in your house right now, expensive air-conditioned air is sliding out under a door, and hot wet August is sliding in to replace it. Weatherstripping is the least glamorous fix we offer and one of the best returns on $89 in the entire home-repair universe. Let’s give it its moment.
Why do door seals matter so much in Florida?
Because the AC season is seven months long and humidity is the real enemy. Every edge gap does double damage: cooled air escapes (the AC runs longer) and humid air enters (the house feels warmer than the thermostat says, so you lower it, so the AC runs longer again). Seals also happen to be your front line against Florida’s other imports — palmetto bugs, ants, lizards with ambitions, and rain-driven water at thresholds.
How do you know your seals are shot?
- The daylight test: dark room, closed door — any visible light around the frame or under the door is a leak.
- The dollar test: close a bill in the door; if it slides out without resistance, so does your cold air.
- The feel test: a warm, slightly damp halo near an exterior door on a July afternoon.
- The tenant: a line of ants using your door sweep as an interstate.
What does the fix involve?
Weatherstripping and seals start at $89 flat: compression seals renewed around the frame, door sweeps replaced at the bottom, thresholds adjusted, and gaps at latch sides corrected — which sometimes means a small hinge tune, weatherstripping’s cousin from the sticking-door family. Twenty minutes per door, years of quiet payback.
The bottom line
$89 flat to stop paying to cool the porch. Do every exterior door in one visit, add door adjustments where summer has been winning, and your AC — and August electric bill — will register the difference. Book the visit, feel smug by evening.
