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. 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, one cartridge 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 10' GRAY GARAGE DOOR THRESHOLD KIT The item arrived on the 5th day after ordering day. I installed it exactly as what the instructions said. Installation was easy and fast ( just remember it would take the product's glue, 8hrs minimum and 12hrs to harden so plan to not drive over or open your garage door(s))! The product looks good and appears it would do everything it said, Oh one more thing the kit comes with a bad/cheap caulking gun, make sure you have a good one nearby before you start this project! It rained 3 days laters for almost all day, but no water in my garage!!! Thanks for this good product! The garage door shuts even and tighter than ever. I highly recommend this product if you got a leaking garage door(s). October 22, 2013
Rated 5.0 out of 5.0 by Awesome product with a great price The item arrived as described. I installed it exactly as per the instructions. Installation was easy and fast. No need to worry about nailing anything, just simply glue did the job. The product does everything it said it would. We no longer have leaves or water in the garage. The door shuts even tighter than before. I hightly recommend this product. January 29, 2013
Rated 4.0 out of 5.0 by Big disapointment When I received the product the package was damaged. The caulking gun was bent , the liquid nails were missing. I went to the Home Depot in Lake Wales to get replacements they said I had to return the package and order a new one. I explained that I had already trimed the rubber to fit. I went home and the went back and bought some liquid nails. I like the threshold but the shipping was awful. The lady at Lake Wales wasn't very helpful. February 25, 2015
Rated 4.0 out of 5.0 by Great looking product I have not installed the product yet, because it is for my home in NM, and I am in MN. For that reason, I cannot evaluate ease of installation or value and quality yet. February 3, 2015
Rated 5.0 out of 5.0 by Did the job! Easy to install & did a good job fixing water problem under garage door. September 25, 2014
Rated 4.0 out of 5.0 by Good solution for garage threshold The threshold is heavy-duty, seems like it will wear very well over the course of time. Take your time and dry-fit it several times prior to installing, to be sure it provides the seal that you're looking for. Once down, it works as described. The only drawback is that the caulk gun they provide is about as cheap as they come, and I bent the handle all to h*** applying the adhesive. Luckily, there were several others handy to fit the bill, and the job went on with no other glitches. Considering it's just a throw-in, I really can't knock the whole shebang too much.

Rated 4.0 out of 5.0 by Good Purchase im very pleased so far with my threshhold. it is very easy to install. September 2, 2014
Rated 4.0 out of 5.0 by Did what I needed, only had one drawback by design. It's on the floor, so anything I want to roll in and out of the garage sometimes gets caught on the seal since it's glued to the garage floor. Toolboxes with small caster wheels especially. If Home Depot starts carrying the snirtstopper I'll upgrade. Either way, no more water coming through the gap where my garage door meets the uneven slope of the concrete floor. July 9, 2012
