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

Is this product exactly 16ft?

My garage door is 16ft; however, if I am to use this product, I believe I would need a couple extra inches on each end.
Asked by: Shawn
I had to trim about 1" off each side.

Does product require any special prep if being used on an older, non finished concrete floor?

Asked by: Jim
My floor was 60 years old and non finished. I just cleaned it with a pressure washer and then wiped it with rubbing alcohol. Worked great.

Is the stripping intrusive?

When kids ride their bikes in and out of the garage or when walking over it, is it noticeably raised? Will it cause a tripping hazard?
Asked by: Wondering
Should not be an issue, I have no problems

16 ft. Black Garage Door Threshold Kit is rated 4.7 out of 5 by 70.

This product was the final piece in the solution to my problem of rainwater infiltrating our garage due to an improperly sloped driveway. We had previously installed a catch basin and underground drainage pipe out to the street, but we still got a bit of water under the garage door. We had an old, inferior (not as tall, not as wide) rubber garage floor seal that we removed and replaced with the Tsunami seal. We just got over 3" of rain, and not a drop entered the garage! Unlike other reviewers, we had no problem with the caulking gun. We used almost 1 entire canister of the Liquid Nails. The hardest part of the installation was cutting the seal to size. Shears worked part of the way; we used an electric knife to saw through the thickest part.

Rated 5 out of 5 by from Tsunami seal 16' garage door threshold kit I love this tsunami seal. For 13 years I have had water coming in my garage, under the door. I have replaced the garage door seal, to no avail. The tsunami seal solved my problem. The kit arrived within a reasonable time, and all parts of the kit were intact. The caulking gun worked perfectly. After reading all the reviews and complaints about the caulking (glue) gun, I was convinced to toss it when it arrived. I had absolutely NO problem using it. Perhaps the issue with this tool is only user error. I wonder how many people try to use the gun before punching a hole in the seal of the glue. I will purchase more for the other 2 garage doors I have.

Rated 4 out of 5 by from Seal great, supplied fun worthless Seal does what it is supposed to do - keeps out the water. No challenge to install and seems durable. The same cannot be said of the supplied gun to be used for the glue. It literally bent in half. Fortunately, I had a spare and finished the install with no issues. If you're gonna supply the gun, spend fifty cents more and include a semi decent model. Otherwise don't supply it!

Rated 5 out of 5 by from Works as designed. Looks nice. Easy to do. Went down well. It may be easy, but you need to follow the directions and lay down lines so it doesn't move when you lay it on the adhesive lines. Before anything that area must be clean and wiped down with alcohol after being wiped down with cleanser. Take your time and think about the money you saved by doing it yourself and then think about how nice it WILL look!

Our garage apron bows slightly in the middle leaving about a 1/4" gap at the ends of the garage door when it is closed. We got mice in the garage this summer! The Tsunami sealed the gaps. No more mice, bugs, or snow creeping in. Not bad to install. I am a 60+ lady and I installed it. It needed some trimming at the ends and I used a hacksaw which worked just fine.

The only concern I had was that it would be long enough for my 16 ft. garage door, and it was about 3" more than the actual size of the door. I felt the product was a bit expensive ,but overall it worked out great.
