Windows & Doors: Spotting Issues & Modern Fixes

Overview
Windows and doors are more than just openings — they’re essential parts of your home’s comfort, efficiency, and safety. When they fail, they can cause drafts, water damage, and higher utility bills. This guide helps you recognize common issues and modern solutions.

Drafty Windows

Signs: Cold air, uneven temperatures, high energy bills
Why it happens: Air sneaks in through frame gaps or worn weatherstripping
How to fix it:
• Apply foam sealant around the window frame (behind the trim)
• Replace old or missing weatherstripping
• Upgrade to Low-E, argon-filled double-pane windows

Pro Tip: Do a candle or incense test on a windy day to detect leaks.

Foggy Double-Pane Glass

Signs: Moisture or haze between the panes
Why it happens: The seal between the two panes has failed
How to fix it:
• Replace the insulated glass unit (IGU) instead of the whole window
• Choose modern IGUs with improved seals and gas fill

Note: This affects both visibility and insulation performance.

Warped or Misaligned Doors

Signs: Door sticks, won’t close, or lets in light
Why it happens: Humidity, age, or frame shifting
How to fix it:
• Upgrade to composite or fiberglass doors
• Re-align or shim the door frame
• Use adjustable hinges to correct small gaps

Failed Weather Seals

Signs: Wind noise, visible gaps, or leaks
Why it happens: Gaskets degrade over time or were poorly installed
How to fix it:
• Replace old seals with high-quality silicone versions
• Re-caulk around the exterior perimeter
• Ensure tight compression when door or window is shut
