Weather Sealing & Weatherstripping
Drafts, driven rain, bugs and AC bills leaking through the door. New seals, interlocks and sill work that make the door tight again.
A sliding door seals differently from every other door in the house: its panels meet on interlocking stiles, slide past brush seals and felt fins, and sit in a sill that Florida rain attacks horizontally. When the weatherstripping is worn — and Florida sun and heat wear it faster than almost anywhere — the symptoms stack up: drafts you can feel, AC that cannot hold the room, rain driven under the door in a real storm, bugs and lizards treating the gap as a driveway, and the whistle on a windy night. We replace worn pile weatherstripping and fin seals, renew the interlock and meeting-stile seals, re-seal the frame perimeter, and address the sill — the channel where most water intrusion actually begins. The result is a door that closes with a soft, definite seal instead of a rattle.
When to Call for Weather Sealing & Weatherstripping
- Daylight visible anywhere around the closed door
- Drafts or a room that will not hold temperature near the door
- Rain water inside the track or on the floor after storms
- Bugs, ants or lizards appearing at the door line
- Dust lines on the floor inside the sliding door
- The door rattles or whistles in wind
What the Visit Covers

- Meeting-stile and interlock seal renewal

Weather Sealing & Weatherstripping Questions
Why does water come under my sliding door in storms?
Usually a combination: worn bottom seals, a sill whose drainage weeps are blocked with years of debris, and wind-driven rain pushing against seals that no longer compress. Each has a fix, and the first job is identifying which combination your door has — sealing a drainage problem shut makes it worse, not better.
Can weatherstripping really affect my electric bill?
A sliding door is one of the largest openings in the house, and a worn seal leaks conditioned air around its entire perimeter, all day. In Florida, where the AC runs most of the year, a tight door is measurable — and the room beside the door simply feels better, which most owners notice before the bill does.
How long does weatherstripping last in Florida?
Pile seals typically give five to ten years here, less on sun-blasted west and south doors. UV and heat are the killers — the pile flattens, the fin cracks. It is inexpensive material; the skill is fitting it correctly so the door still slides freely.
Will new seals make the door harder to close?
Correctly fitted seals add a slight, definite resistance right at the closed position — that is the seal compressing, and it should feel like quality, not effort. If a door needs a shove to latch after sealing, the seals are wrong or the panel needs adjustment, and we do not leave it that way.
