So winter’s rolling in.
You’re inside, minding your own business, when suddenly—a draft.

No worries.

🧰 What You’ll Need (No Caulk, No Problem):

Weatherstripping tape — $3 to $5
Plastic window insulation kit (aka shrink wrap) — $5–$7
Draft stoppers or DIY towel snakes — Free if you get creative
Bubble wrap (yes, really)
Scissors and a hairdryer (optional but helpful)

1. Weatherstripping Tape = Your Drafty Window’s BFF

This is the easiest and most affordable trick in the book.
It’s basically foam tape with adhesive on one side. Just peel, stick around the inside of the window frame, and done.

It blocks out drafts.
It’s cheap.
And best of all—no mess, no tools, no “I need an adult” moments.

You can even use it on top of old, cracked caulk for bonus sealant power.

2. Plastic Film Window Kits (a.k.a. Shrink-Wrap for Grown-Ups)

Yes, it looks weird at first. But it works. You stick the clear plastic around your window frame, then use a hairdryer to shrink it tight.

Result?
A nearly invisible barrier that keeps warm air in and Jack Frost out.

It’s like giving your windows a cozy winter jacket.

3. DIY Draft Snake (It’s Not a Real Snake, Calm Down)

That little draft coming in from the bottom of your window? You can block that with a rolled-up towel or blanket.

Feeling fancy? Fill a long sock with rice, tie the end, and boom: homemade draft stopper. Bonus points if it looks like a stuffed animal. Instant charm + insulation.

4. Bubble Wrap: Ugly but Effective

For windows you don’t need to see through (like in a garage or laundry room), slap some bubble wrap on them.

Spray a little water on the glass.
Press the bubble side against the window.
It sticks and insulates. Like magic. Ugly magic. But still magic.

And yes—you can still pop the bubbles if you get bored. Dual purpose.

5. Close It Up Tight

Sounds basic, but just locking your windows creates a tighter seal. A lot of drafts sneak in because windows are slightly ajar without you realizing it.

So give them a wiggle and make sure everything’s snapped, latched, and locked.
