StopGap Weatherstripping

Price range: $19.99 through $25.99

Your window has a gap. StopGap covers it.
It sits where the two sashes meet and shuts the draft out. The window still opens.

✅ 35% larger, so it covers more of the gap

✅ 25% cheaper than the old one

✅ Two pieces seal one window

✅ Two nails, no special tools, less than 5 minutes

✅ No caulk. No new windows. No contractor.

Choose polished nickel or unlacquered brass. The smaller Unlacquered Brass is being retired. Once it’s gone, it’s gone.

New and Improved! What Changed?

We made StopGap bigger. The new size is 35% larger than the one it replaces, in nickel or brass, and it costs 25% less. It covers more of the joint. Bigger for less?

  • NEW SIZE
  • 35% larger, so it covers more of the joint
  • Costs 25% less than the previous model
  • Adds polished nickel
  • The size we're making from here on!
  • PREVIOUS SIZE
  • Smaller, so it covers less of the joint
  • Costs more
  • Not being made anymore
  • Gone for good once each finish sells out

The original StopGap did its job. After years of testing, we redesigned it and added a polished nickel finish.

Install is a Breeze

I got them for my parents home in Texas. They said the solid bronze looks great, and now their windows aren’t drafty!

Excellent Product

I’ve got an old hunting camp up north. It’s not in the budget to replace the windows. My son said he fixed it but he just caulked the windows shut. I found these and fixed it right.

You’re not just fixing a draft, you’re honoring the craftsmanship of your historic windows. These windows have lasted through generations, a testament to their quality. Modern windows can’t replicate the charm or the enduring legacy of your originals. Plus, preserving them is an eco-friendly choice, reducing waste and the environmental impact of manufacturing new windows.

Remember: Your historic windows are more than just panes of glass; they’re a part of your home’s story. With Stop Gap, you ensure that story continues, all while enhancing comfort and saving money.
