Product Overview

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.

Customer Questions & Answers

There is a height dfifference between my garage floor and driveway with the garage floor being higher (3/4 inch). If the seal extends beyond the epoxy garage floor out onto the concrete driveway, will it wrap around the ledge and adhere properly to the driveway? Is there any special preparation required to prep the concrete? Dirt and sand collect in front of the lip; sweeping and even vaccuming doesn't remove all the particles. I am actually hoping to use the Tsunami Seal to encase the lip completely so that the dirt and sand and weeds don't make themselves at home there anymore. Will this product work as a bridge between these two surfaces?
Asked by: Beachy
No, the Tsunami Seal must be mounted on a flat surface.

If it rains soon after the seal is installed will it effect the adhesive?

Asked by: Tam
After 24 hours, it will not effect the adhesive. Before 24 hours, it would depend upon the volume of rain.

My original garage door seal was not stopping the rain from coming in. I watched the video, and it was clear and concise on how to install the seal. After the installation of the Tsunami Seal was complete, it absolutely stopped the water from coming in after a driving rain. I would recommend it to anyone.
