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 in. 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 and a metal caulking gun and color installation instructions. Comes with a lifetime warranty.

Rated 4.7 out of 5 by 12 reviewers.
Rated 5.0 out of 5.0 by great purchase we would get water in our garage all the time . So my husband heard about this product and we decided to purchase it. It was easy to install and so far it works great. I would recommend this product. January 3, 2015
Rated 5.0 out of 5.0 by Stop the flood I was doubtful that this product would solve my problem of water getting under the garage door.I had previously installed new door seals from the manufacturer.All to no avail.So I gave the Tsunami a shot.Installation was fairly simple as were the instructions.About an hour including prep and cleanup.To this day (a month later) not one drop of water in the garage.Don't waste time or money on other methods.They don't work.I know.I did.

Rated 5.0 out of 5.0 by We have our sanity back! We bought our home a couple of years ago and for the most part love it. Every real rain with the garage doors down produced a puddle in our garage (not so loved). We tried several things but the puddle continued. The threshold strip was simple to put on just follow directions. We are dry and the seal looks professional and permanent. I would recommend this product, for us it actually solved the problem for good! March 25, 2014
Rated 4.0 out of 5.0 by Great Product, but bad caulk gun The seal was great it worked as stated. But the caulk gun they sent just bent when we tried to use it because it's a real cheap gun. The local store made it right by giving us a new gun and a replacement tube of glue. :-) October 4, 2011
Rated 4.0 out of 5.0 by good threshold product instructions were good in that make sure product is warm prior to install if in cold weather. just throw the chaulk gun they provide away it is junk. product easy to cut with a knife to length and work with November 11, 2014
Rated 5.0 out of 5.0 by Good Product The rubber threshold is quite rugged, but easy to cut and install. I only used one tube of a adhesive, so now I have a spare tube. The caulking gun if fairly cheesy, but no matter. I'm very happy with the threshold. January 24, 2012
Rated 4.0 out of 5.0 by Overall good value and easy to install Exactly what I needed and was easy to use. Great having the liquid nails included. Only thing that could have been a plus would be the inclusion of small molding pieces for edges. April 3, 2012
Rated 5.0 out of 5.0 by Works like it should works great in my garage keeps the water out on heavy rains days ! February 18, 2014
