Is Snirt Invading Your Garage?

Are Snow, Dirt, Leaves, Mice, Bugs, Cold Drafts and Heat Loss causing a Monstrous Mess in your Home Garage, Shop Building, Warehouse, Loading Dock or other area? Stop it with a SnirtStopper™ Premium Door Seal.

SnirtStopper™ is a revolutionary, easy to install garage door seal that actually stops snow and dirt or ‘snirt’! Our patented BottomSealer™ and SideSealer™ keeps out rain, snow, dirt, leaves, rodents, insects and helps prevent garage door freeze-down while saving energy by sealing out the cold, creating an air-tight seal that traps heat inside where it belongs for a warmer, safer work area and home!

Millennial Farmer

SnirtStopper is tough enough to withstand the harshest conditions, but don’t just take our word for it. Hear what Zach “The Millennial Farmer” Johnson had to say when we visited his farm a year after his first install!

As seen on YouTube with the Millennial Farms and Larson Farms!

Larson Farms

SnirtStopper is also proud to have been asked to help seal up the shop at Larson Farms. Watch to the end to see how we installed a double seal for an extra snug fit!

For a 68 year old man with no real good DIY skills and without any help I completed the install in about 2 hours. The hardest part was I have a metal strip on the inside bottom of my garage door and my wife is a hoarder so our garage is full to the door. I had to drill the first several holes and then install the bottom seal but after that is was really easy. Of course I have watched Jeff install Larson Farms and several other YouTube channels so it was pretty easy. I did the bottom seal inside, the top seal and both sides seals. Definitely recommend.

I installed the bottom seal to close open gaps when the door was down. It was easy and straightforward to install and the results of it sealing all the gaps was so effective I then ordered the enhanced side and top sealer. Again, as with the bottom seal, installation was easy and straightforward. I have no doubts at all the my garage will be dryer and much warmer than past years. The photos show the dramatic before and after effects.

Ordered two bottom garage door sealers was hesitant at first putting them on but after viewing the videos that SnirtStopper has it was about a 45 minute job attaching them very easy to do. The product definitely seals the bottom of the door Thank You SnirtStopper for a great product!

Installation was easy. Needed this for all the reasons mentioned on the site plus a minor flooding issue. It only happens once a year. Hoping the seal will hold back most of the water. Will update when it happens again.

These things work great. This is the 3rd door I've put one on. The first door I did was about 6 years ago and it still is in excellent condition. Stop the Snirt!

This was the only product I could find that was designed for extremely uneven garage floors and it did exactly what I needed it to do, which was primarily block out snow in the winter. I would recommend this product to anyone looking to seal their garage from the elements.

This product was very easy to install and we noticed the difference right away. We have a basement with a garage door at our lake house and we could feel the cold air from the ac coming out of the sides and tops of the door until we put this up. Sealed it immediately. Keeps the bugs out too.

The left side of our garage floor has sunken so much that we have a 3 1/2” gap, and even the large bottom gasket the garage door company installed can’t close it off. So, after trying a DIY of inserting a foam tube in the gasket, I found SnirtStopper online. Ordered a 3-foot length of their XL Premium bottom sealers and, Voila! Problem solved. Easy to install, doesn’t change the exterior view, and the only meaningful change on the interior is a tight seal!

Just supplying some feedback regarding the snirtstopper I installed on my 8ft wide garage door.  Installation was easy.  Followed directions closely including stretching it during application and using the proper vertical location which eliminated any gaps.  This was verified with bright sunlight in the dark garage.  The issue I have come across is that as rain hits the door and travels down to the threshold, it leaks into the garage at the edges causing water to pool inside against the wall.  I added various items including foam blocks and sprayed sealer on the blocks to create a dam inside the door behind the snirtstopper.  While I don't expect any refund or explanation, I just want to say that it should not be marketed as a device that prevents water from leaking past the door.  It certainly blocks dust, dirt (no snow in Phoenix area) so for that it is great.Thanks for listening.  It is a good product and meets many of the claims in the marketing information.

Absolutely fantastic product. There is nothing on the market that is able to fill in those 2+ inch gaps on the sides of the garage door. My neighbor suggested the SnirtStopper and swears by it. Excited to get in before the CA heat and critters kick in.

A five star product. Purchased a bottom seal and the top and side seals. My garage door is 16’ wide and 8’ high and I had little faith that I would ever get it sealed. It gets pretty cold and wet in Montana, first winter in this house and I had given up on trying to use the garage for a shop. Looked at other options for the seal on the door but nothing came close to doing the job. Saw an internet ad for the snirt stopper and watched the video. It was guaranteed to make a seal, and it was cheaper than a new door so I did the order. Seals arrived fairly quick and were very well packed with all the screws that I needed for installation and some very comprehensive instructions with a link to the video of the install. All I can say is wow, no dirt or rain or snow and I can even think about heating the garage because it stays 10° warmer with all the holes sealed at the bottom and the top and sides. Big thanks Snirt Stopper, you saved my the cost of a new garage door.

Our shop is up on a hill with four 14x20 overhead doors. We always had the wind finding its way blowing thru the cracks and crevices. We could tell right away during the installation of the SnirtStopper of how effective it is of keeping the doors sealed tight. We are VERY impressed. I have already let a friend of mine know about the SnirtStopper for his shop, and he is very interested. I HIGHLY recommend the SnirtStopper.
