Window Leaks? Science and 4 Sealant Fixes

Sealant #1: Silicone Caulk—Your Weatherproof Warrior

Silicone caulk is flexible, waterproof, and lasts for years. It’s perfect for sealing gaps around window frames where movement happens. Pro tip: Clean the area first and apply in a smooth bead to stop leaks dead in their tracks! 💪


Sealant #2: Acrylic Latex Caulk—Easy and Paintable

If you want a fix that blends with your walls and paint, acrylic latex caulk is your best friend. It’s easy to apply and cleans up with water. Not as durable outdoors but great for interior leaks! 🎨


Sealant #3: Weatherstripping—The Quick Fix

For leaks between the window sash and frame, weatherstripping is a game-changer. It’s a flexible foam or rubber tape you stick along edges to block drafts instantly. Plus, it’s super affordable and DIY-friendly! 🛠️


Sealant #4: Expanding Foam—Fills Bigger Gaps

Got larger cracks or gaps? Expanding foam seals those tough spots like a champ. It expands to fill voids and insulates at the same time. Just spray, wait for it to set, then trim the excess. Caution: Use sparingly and away from visible spots! 🧯
