ND/MN Residents Know Exactly What We're Talking About
Every fall it starts. The wind picks up, the temperature drops, and you walk into your garage to find a ridge of snow and grit pushed under the door. Snirt — that uniquely upper Midwest combination of snow and dirt — finds its way into garages, shops, machine sheds, and entryways no matter how new your door is.
And it's not just the snirt. Cold air bleeds in under every door, raising your heating bill all winter. Mice and other rodents find the gaps and follow them inside. The floor stays damp. The garage stays cold. The shop is miserable to work in.
You've probably already tried the foam weatherstripping from the hardware store. It compressed after one winter, tore, and let everything back in anyway. That's not a you problem, that's a product problem.
There's a fix that actually lasts. And we install it.
❄️ Cold Air & Drafts — Energy loss you're paying for every month all winter long
🐭Rodents & Pests — Mice follow the cold air gap straight into your garage and home
SnirtStopper: The Last Door Seal You'll Ever INSTALL
SnirtStopper is a complete door sealing system, not just a bottom sweep. A full installation seals the bottom of your door against the floor, the sides of the frame, and across the top, eliminating every gap that cold air, moisture, rodents, insects and debris can find.
The system is Kevlar-reinforced, backed by an industry-leading 25-year warranty, and made in the USA. It won't shrink, loosen, or fail in extreme temperatures — which matters when your garage sits at -20°F for three months straight.
SafeYard’s Dakota Door Seals is your authorized SnirtStopper dealer and professional installer for the Fargo-Moorhead area. We supply the product, we do the installation, and we stand behind the results.
Industry-Leading 25-Year Warranty — Made in the USA
SnirtStopper products carry a 25-year warranty. The foam weatherstripping from Fleet Farm doesn't. This is a commercial-grade product engineered specifically for northern climates and it's built to outlast every winter you'll ever throw at it.
🌨️Snow & Dirt — That ridge of crud pushed under the door with every wind event
💧 Moisture & Debris — Wet floors, tracked-in dirt, and damage to stored items
A Complete Sealing System: Three Products, Every Gap Covered
Creates a tight seal between the bottom of your door and the floor, blocking drafts, moisture, snow, debris, insects, rodents, and snakes. Features a self-adjusting wiper seal that continually conforms to the floor surface, a high-density foam core, and Kevlar-reinforced woven polyester construction that stays flexible and resilient for years. Available in four sizes — Original seals gaps up to 1", Large up to 1.5", XL up to 3", and XXL up to 4" for uneven floors and oversized doors.
Best for: Residential garage doors, commercial overhead doors, machine sheds, barn doors, and any application with an uneven or large floor gap.
Eliminates gaps up the sides and across the top of your door frame — the places most installers ignore and most seals miss entirely. Kevlar-reinforced material with a built-in thermal strip that adds insulation value around the full door perimeter. Won't shrink, loosen, or fail in extreme temperatures, wind, or severe weather. Completely seals out cold drafts, insects, spiders, rain, snow, dirt, sand, and leaves.
Best for: Any door where you want complete perimeter sealing, pairs with the BottomSealer for a fully sealed door on all four sides.
The most versatile product in the SnirtStopper lineup. Works on virtually any door type — bi-fold, hydraulic, slider, and entry/service doors. Features a robust thermal insulation tube (0.75" or 1.25" core) for superior energy efficiency. Kevlar-reinforced woven polyester resists tearing and provides long-lasting performance around irregular door edges and frames.
Best for: Entry doors, mudroom doors, specialty commercial doors, bi-fold and hydraulic doors, and any door where a standard seal doesn't fit or reach.
🎨 Available in 10 Colors —White, black, tan, gray, charcoal, green, red, dark brown, sand, stone, and terra bronze. We'll match the right color to your door and trim so the finished install looks clean and intentional, not like an afterthought.
Where We Install
Residential
Garage Doors — Single, double, and smaller golf cart garage doors. Our most common residential install. Most are complete in under an hour per door and the difference is immediate.
Entry & Mudroom Doors — Side entry and walk-through doors where cold air and moisture sneak in all winter. Often overlooked, always worth sealing.
Basement Doors — Almost always undersealed. One of the biggest sources of cold air infiltration in upper Midwest homes.
Commercial
Overhead & Loading Dock Doors — We work with building owners, property managers, and business owners to seal high-traffic commercial doors properly. Our XL and XXL BottomSealer options handle the large gaps common in commercial settings.
Entry & Exit Doors — Business entry points where customer-facing appearance and energy efficiency both matter. Color selection means the finished seal looks intentional.
Agricultural
Machine Sheds & Shops — Keep your equipment barn from becoming a mouse house and your shop warm enough to actually work in all winter. Our XL and XXL options were built for the uneven concrete floors common in older ag buildings — sealing gaps up to 4 inches.
Livestock Barns — Draft control matters for animal comfort and health. We install on standard and large overhead barn doors.
Grain Storage — Seal gaps that allow moisture, pest, and debris infiltration that threatens stored grain and equipment.
Got an uneven floor or an oversized door?
Our XL BottomSealer seals gaps up to 3 inches and our XXL seals up to 4 inches, specifically designed for uneven floors, older buildings, bi-fold doors, and hydraulic doors where standard seals have never worked. If you've given up on sealing a door because the gap is too big or the floor is too uneven, call us. We have a solution.
Simple Process. Permanent Results.
Request a Free Quote — Call, text, or fill out our form. Tell us your door types, sizes, and location. We'll get back to you quickly with a clear price (no surprises).
We Come to You — Our installers arrive with everything needed. No trips to Menards, no waiting on parts, no DIY headaches.
Measure and Custom Fit — Every install is measured and cut precisely for your specific door, floor surface, and gap size. We select the right BottomSealer size for your actual gap — Original, Large, XL, or XXL — so it fits correctly the first time.
Professional Installation — Clean, fast, and done right. Most residential garage door installs take under an hour per door. We match the product color to your door & trim for a finished, professional result.
Done — Walk back in, close the door, and feel the difference immediately. No cold air. No gap. No dirt. And a 25-year warranty backing it up.
What Does It Cost?
Professional installation of a complete SnirtStopper system on a standard double garage door starts at $350–$500, depending on door size, gap size, and the level of protection you choose. Multi-door and commercial installs are priced by project: we'll give you a clear number before any work begins.
Compare that to one winter of elevated heating costs, one mouse infestation in your garage, or another season of sweeping snirt off your shop floor every morning. Most customers tell us it pays for itself faster than they expected.
Serving the Fargo-Moorhead Area and Beyond
Dakota Door Seals serves residential, commercial, and agricultural customers across the greater Fargo-Moorhead region including Cass County ND, Clay County MN, and surrounding communities. We travel for farm and commercial projects: reach out and we'll let you know if we can get to your area.
Who Is Dakota Door Seals?
Dakota Door Seals is owned and operated by Alec and Alicia Winmill: the same team behind SafeYard Pest Control, which has served the Fargo-Moorhead area for 10+ years and earned hundreds of five-star reviews from neighbors across the region.
We became authorized SnirtStopper dealers and installers because we kept seeing the same problem at the properties we service: gaps under garage doors letting in cold, moisture, pests, and debris. We fixed it on our own property first (we installed SnirtStopper at our home last year). Then we started fixing it for customers. Now we're doing it professionally as a dedicated installation service.
We know this region, we know these winters, and we know what it means to stand behind work we do for our neighbors. Same owners. Same standards. Same phone number.
