Water appearing near a sliding door during a heavy rain, a damp spot on the floor, a wet windowsill, a musty smell after a storm, is one of the most common calls we get in South Florida, and one of the most commonly misdiagnosed by homeowners.
Why It's Easy to Misread
Water intrusion around a sliding door can look like a roof leak, a window issue, or a slab problem, especially if it only shows up during wind-driven rain. Homeowners often spend money addressing the wrong thing, recaulking a window, checking the roof, before realizing the actual source is the sliding door's weather seal, track, or bottom rail.
What's Usually Actually Happening
- A worn or missing weather seal along the door's edge or track
- A bottom rail that has corroded or no longer sits flush
- A track that has settled or tilted slightly, letting water pool instead of drain
- A panel that isn't closing fully (see our note on doors that won't close all the way), leaving a literal gap for water
Why Caulk and Sealant Aren't the Fix
A common DIY response is to caulk around the frame. That can mask a symptom temporarily but doesn't address a failed seal inside the track system or a misaligned panel, and trapped moisture behind fresh caulk can make the underlying problem worse before it's visible again.
Why This Needs a Professional Diagnosis
Finding the actual entry point requires testing the door under conditions that simulate wind-driven rain and inspecting the seal, rail, and track systematically, not guessing based on where the water pools inside. Get it wrong and you'll be back to square one during the next storm.
