Spot the Problem and Seal It Up

Feeling a chill near your windows—even when they’re closed? Drafty windows are one of the most common energy drains in older homes. The good news? Many can be fixed without a full replacement.

How to Tell If a Window Is Drafty

You might notice:
💨 A cold breeze near the window, even when shut
🧊 Higher heating bills in winter
🪟 Curtains that move slightly when it’s windy outside
🧱 Uneven temperatures in certain rooms

Try the **candle test**: Hold a lit candle near the window edges. If the flame flickers, there’s air movement—aka a draft.

Common Causes of Window Drafts

🪟 Worn-out or missing weather stripping
🛠️ Cracks in caulking or window seals
🧱 Poor insulation around the window frame
⏳ Warping or shrinking window materials (especially wood)

DIY Fixes for Minor Drafts

🧵 **Weather stripping** – Replace or add foam strips around the sash.
🪟 **Caulking** – Re-caulk any cracks around the window trim.
🪟 **Plastic film kits** – A temporary fix that adds an extra barrier during cold months.
🧰 **Draft stoppers** – Fabric draft snakes can help as a quick fix at the bottom of windows.

When It’s Time to Replace the Window

If your windows are decades old, or you’re dealing with visible frame damage, glass seal failure, or rising energy costs, replacing the window may be the smarter long-term choice. Modern windows are designed to be airtight and energy-efficient, often with low-E coatings and insulated glass.

Why It Matters

Drafty windows don’t just make you uncomfortable—they cost you money in the long run. Fixing the issue improves your comfort, lowers utility bills, and adds to your home’s value.
