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 5.0 out of 5.0 by Very good product It was easy to install,I wish it would have been delivered quicker than 9 or 10 days. November 3, 2015
Rated 5.0 out of 5.0 by Just what I needed The garage floor weather strip Is just as it appears online. Time from my order to arrival of the kit was just a few days. Instuction sheet was good. Although there has been no rain or snow to test the strip's effectiveness, it appears to be a quality product. It was nice and convenient to have the liquid nails, caulk gun and weather strip in a kit. October 14, 2015
Rated 5.0 out of 5.0 by Garage door threshold This installed easily & solved the issue of water coming in under the garage door. The kit even included the glue and the caulking tool to install. September 15, 2015
Rated 5.0 out of 5.0 by Great Product The kit comes with everything needed to do it yourself. Everything is straight forward; easy install. My garage floor was not poured quite level and had some daylight on one end. Now the door seals completely. September 1, 2015
Rated 5.0 out of 5.0 by Tsunami garage door threshold kit I ordered 16 feet for my two 8 ft doors. Easy to cut to fit and caulking gun made it easy to spread the Tough As Nails (TAN) caulking. I followed the easy direction by rolling out the threshold strip inside our house to warm up and remove the curl and when I put it on the caulking it was perfect. 24 hours later both vehicles back in the garage and the rain seeping under the garage doors has stopped. A definite good buy. Hint use a screw driver to pierce the TAN caulking tube before you squeeze the caulking gun otherwise you will complain that the Caulking gun is cheap as others have complained. It worked fine for me. December 23, 2014
Rated 5.0 out of 5.0 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 5.0 out of 5.0 by Tsunami Seal 16' Easy to install and works as advertised. I would buy this product again. January 6, 2015
Rated 5.0 out of 5.0 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
