The Tsunami Seal Garage Door Threshold Seal mounts to your garage floor creating the perfect seal between your door and your garage floor. The Garage Door Threshold Seal creates a tight seal for your garage door which will keep leaves, dirt, water and snow from being blown under the garage door by the wind. Also, if you have a sloped driveway or an uneven garage floor and water is seeping under your garage door, the Door Seal adds a 1/2 tall barrier to the garage floor. The Door Seal will also help keep out unwanted insects and snakes. By creating a better seal, your garage will stay warmer during the winter and cooler during the summer, helping to keep your energy cost down. The Door Seal works great with all types of garage doors including roll up doors, hinged wood doors and walk through doors. The one piece strip is permanently secured to the garage floor with the included Liquid Nails Polyurethane Adhesive. Each kit includes the one piece Threshold Seal, two cartridges of Liquid Nails Ultra DutyTM Poly Adhesive, a metal caulking gun and color installation instructions. Comes with a Lifetime Warranty.

Rated 4.5 out of 5 by 19 reviewers.
Rated 4 out of 5 by Good Product The threshold was very easy to install. The caulking gun that came with the kit was worthless, it is very flimsy and not worth even trying to use with the caulk. Otherwise, I would have given it five stars and excellent across the board. Don't hesitate to buy this product. October 2, 2014
Rated 5 out of 5 by Tsunami seal This a very well designed product. easy to install and I no longer get water in my garage every time it rains July 15, 2014
Rated 5 out of 5 by Garage Door Threshold Since we owned house (20 years) I have had problems each winter with rain/snow mositure coming into garage under door. I installed the threshold before winter arrived and I had no problem this winter and we had some severe storms. I'm am very pleased with your product and it was easy to install. Bill January 25, 2011
Rated 5 out of 5 by This product works great This thing works great! I've had water coming under my door every time it rains and snows. So far, during the thaw and rain, my garage is dry. Way cheaper then redoing the concrete. February 20, 2014
Rated 5 out of 5 by Outstanding product Wow! For the first time in years, no water came in under the garage door when it rained! I only wish we'd done this sooner! The threshold was easy to install, the instructions were clear, and the materials provided were all that were needed. The only reason I don't rate installation "Excellent" is that a note should be added to the instructions to not use excessive adhesive -- just the 1/4" bead specified. We must have used too much, since we then had to work to get the "outside" lip down tight against the concrete. May 8, 2012
