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 5.0 out of 5.0 by Tsunami Seal Easier to install than I thought. It does the job it is supposed to do very well just had our first snow fall with a north wind that usually blew the snow under the door into the garage. With the new seal it is very clear no snow blew in. That means no snow or water coming in under the door, no frozen door seal to the garage floor hoorah. This seal works great. Thank you Tsunami.

Rated 4.0 out of 5.0 by Overall good product but ,supplied, installation tool of poor quality. The product, Black door threshold kit, certainly was sufficient for the application but the Caulking Gun, which was supplied as the installation equipment, was inferior. The caulking gun construction was of light gage sheet metal and promptly collapsed after a few squeezes. Fortunately I had a commercial Caulking Gun in my truck to finish the project. For the cost of the kit the installation equipment should be a bit beefier. I would recommend the threshold but should replace the flimsy caulk gun with a more sturdy gun. We have had occasion to test the threshold with rain and it holds very well. February 18, 2014
Rated 5.0 out of 5.0 by Easier than I expected I'd been looking at getting a threshold kit for my garage door for years. Over the years the concrete slab for the driveway and the garage floor have moved, creating a gap between the bottom the garage door and the concrete on one side. However, I was concerned that it would be difficult to install, and not work with my painted floor. The latter is no longer a problem as the floor is well seasoned, but the former was still a concern. I didn't need to worry. Just roll out the threshold, let it uncurl and lay flat (easier in warm weather), cut it to size with a sharp utility knife (use a straightedge to get the best cut), close the door and push the threshold into place, and mark the inner edge of the strip. Do the same on the outer-facing side, and you're ready to lay down the adhesive. Three lines are all it takes, and then place the threshold over the adhesive while making sure it stays between the lines you drew. Keep a putty knife handy for any adhesive that oozes out; you can scrape it up easily before it dries. Then lower the door and wait 24 hours for it to take a permanent set. That's it! Easy. Plus it has really reduced the amount of dust and dirt driven under the door and into my garage. June 17, 2014
Rated 3.0 out of 5.0 by Tsunami rain stopper The caulking gun came bent and is extremely cheaply made. April 21, 2015
Rated 5.0 out of 5.0 by great product So easy to install and it actually does what it was built to do. The absolute problem solver for garage door seals. Buy one now you won't regret it. March 10, 2015
Rated 5.0 out of 5.0 by Perfect For years I had water seep under the door. This product did the trick no more seepage. It was easy to install by myself and I needed no extra tools other than a knife to adjust the length. I am very pleased with the functionality and appearance. If you happen to have a little glue ooze out along the edge it easily can be cleaned up with a paint scrapper once dried. June 19, 2013
Rated 4.0 out of 5.0 by Great Product (but don't rely on the caulk gun) Everything worked great -- but the caulk gun was a complete piece of junk; it broke halfway through the first tube of caulk. I would have been happy to pay more for a caulk gun that would last more than one minute. If you order this, just make sure you have a caulk gun on hand October 14, 2014
Rated 5.0 out of 5.0 by The best Garage threshold/seal I've ever seen and implemented. I would suggest having a partner helping out. It complements the the garage door and garage. nothing gets in. its awesome. December 23, 2014
