Now Available as a Side and Top Seal!

Our SnirtStopper™ BottomSealer™ Premium Garage Door weatherstrip seal has been such a huge success that we decided to introduce a similar seal to work on the sides and top of garage doors, too! Use our new SideSealer™ to eliminate the gaps up the sides and across the top of your garage, commercial or walk-in doors to completely seal out cold drafts, insects, spiders and more.

Can Be Installed With or Without the Old Seal!

Our SideSealer™  is so versatile that it can be placed right over any existing garage door seals, or the old seals can be removed and the SideSealer™ installed solo directly onto the garage door frame. It’ll seal great either way!

The Side/Top Sealer is 3 inches wide and also includes a thermal strip to help insulate. However, we can also make this product in custom sizes as wide as needed for specific job requirements.

How SnirtStopper Top and SideSealer works

Sealing the sides and top of a garage door: Before and After

How long do they last?

How to Install StopTheSnirt™ SideSealer™ and TopSealer™

The SideSealer™ is constructed of the same heavy-duty, Kevlar reinforced woven polyester material as our popular BottomSealer™, so you never have to worry about it tearing or wearing out no matter how many times you raise and lower your garage door. Unlike conventional vinyl and rubber seals that eventually rip, dry out and become brittle and stiff, the SideSealer™ material is uniquely designed to stay pliable and resilient for years, pressing firmly and conforming to variations in your garage door for a tight fit that eliminates all gaps and stops snirt in its tracks!

Works on all Types and Sizes of Doors!

And just like our SnirtStopper™ BottomSealer™, our SideSealer™ and TopSealer™ also works on all sizes of walk-in doors and all types of commercial bay doors, including Overhead, Sliding, Bifold and Hydroswing Hydraulic Doors. SideSealer™ can help to fully seal worn out, drafty Docking Bay doors in your shipping and receiving department, making it easier to heat and cool, saving energy costs and keeping employees happier!

Comes In Several Colors

Even better, SnirtStopper™ SideSealer™ comes in your choice of several great colors designed to blend with any home and color scheme. Plus, each option comes with matching self-tapping screws for easy installation and a factory look! The colors work so well, the seal actually helps trim out your door, giving your home a quality appearance and enhancing curb appeal.

Ordering is super easy!

We offer our garage door side and top seal kits in common sizes to ensure you get just what you need to seal your door tight! Just measure the height and width of your garage door and select the kit that fits. Each kit comes with 2 side seals and 1 top seal. Got an oddly sized door that’s not listed? No problem! We also offer SnirtStopper™ SideSealer™ by the foot. Just determine how much you need and order just the right amount.
