How to Prevent Mold Around Your Sliding Glass Door
🦠 The Hidden Problem in Many Florida Homes
Living in Florida means you’re constantly battling humidity — and one of the most overlooked areas where this shows up is around your sliding glass door frame.
That black or greenish buildup you see at the base of your door? That’s mold — and it doesn’t just look bad; it’s bad for your health and your home’s structure.
🤢 Why Mold Forms Around Sliding Doors
Humidity and condensation collect near aluminum frames and glass
Improper sealing allows water intrusion during storms
Lack of airflow in door corners encourages mold growth
Worn weatherstripping lets moisture seep inside
🛡️ How to Prevent Mold — A Proactive Guide
✅ 1. Inspect Weatherstripping Regularly
Old seals crack and let water in. We recommend replacing weatherstripping every 2–3 years in Florida homes.
✅ 2. Clean Tracks Weekly
Use a 50/50 mix of vinegar and water to wipe away early mold spores from the track and door frame.
✅ 3. Use a Dehumidifier
Especially in homes near the coast or with poor ventilation.
✅ 4. Install Mold-Resistant Caulk
If your sliding door frame was installed with standard caulk, you may need an upgrade.
🧰 Bonus Tip from Alonso Sliding Door Repair:
When we service a door, we always inspect for mold-prone areas and can reseal or caulk as needed during the visit.
