Review: Good quality - Came pretty early,was packaged nicely and fits my door well,comes with extra adhesive in case it’s not sticky enough,it’s similar to tape when putting it on the door overall it’s simple to put on and works well
Review: Easy to Apply and Install on Doors - These are very effective for reducing draft under doors - especially the front or back door of a house. I recommend laying them flat a couple of days so that when you attach to them to the door, they stay level and flat and seal draft from underneath the door. Overall, very noticeable improvement.

## Questions & Answers

**Q: can I double one on top of the other to cover a larger gap? If not, please rec a product that covers a 2" gap. Thanks!**
A: No, that won’t work, I tried! Order this instead. It’s more expensive but super thick and sticky, comes with brads as well and closed over a 2” gap on my screen door. Yahhh …no more critters can get in! I’m ordering another set today to do both sides of the storm door.

**Q: Can it come off easily without ruining door?**
A: Yes, mine did. You may need to apply a blow dryer to heat it up some. But it comes off.

**Q: Will this damage a painted door or wood door upon removal?**
A: Yes, it destroye the paint on my bedroom door don't do it!

**Q: Does this work better when placed inside or outside the door?**
A: If it is an interior door like a bedroom door, you can put it on either side.  If it is a main door leading to the outside, I recommend using it on the inside.  You can put it on the outside but weather conditions will deteriorate the quality of the product over time.

### ⭐⭐⭐⭐ Works great
*by K***T on December 28, 2025*

We had a really bad draft coming from our front door and this has helped a lot! Was easy to put on the door and has held up well. Only downside is I haven’t found a thin enough door mat that doesn’t get shoved over every time I open the door.
