5 Best Garage Door Threshold

Weather Defender Original Ultimate

  • Length: 16 Feet 5 Inches

This threshold is the last garage door seal you’ll ever need. You won’t need to worry about a wet garage ever again with this threshold seal.

What I love about this threshold is that you can purchase it in all the standard garage door sizes from 8’5″ to even the largest size of 20’8″. You won’t be limited when installing this seal and it can still be cut to fit any odd-sized garage door.

Installation is a breeze, all that’s required from you is to line it up with your garage door, put down the adhesive and stick it to the floor. When all said is done, you’re looking at about a 10-minute installation. Beats calling the repairman!

Another great feature from this threshold is the ability to keep out rats. They can sneak through the bottom of your unsealed garage door, and this threshold will keep them out for good.

You can also drive over this seal without worry as it’s been designed to uphold its structural integrity. Any type of garage door is also fine, roller, up and over, side hinged or sectional, this garage door threshold fits it all.

One downside of this product is that the adhesive that it comes with it can be weak as described by purchasers. I would advise getting some gorilla glue if you decide to go with this seal. Other than that, I think this threshold seal is going to be your best bet!

  • Keeps out water, dirt, leaves and rain
  • Can fit nearly any length garage door
  • Adhesive can be tricky to use

Garage Door Bottom Seal

  • Length: 20 feet

This threshold seal is perfect for anyone looking to keep out the water out of the garage without breaking the bank.

You’ll be able to keep out any creepy crawlies, water, dirt, and snow with this threshold. It’s created out of PVC rubber which will hold its own when being driven over and during harsh weather.

Installation is the same as the other garage door thresholds. You measure the distance of your garage door, cut down the threshold seal to the length of your garage door, and then mark the floor where the seal will meet the inside of your garage door. Place the adhesive down and you’re good to go!

If you live in a place where you have a heavy wet season, this threshold seal will keep your garage waterfree. Enjoying your garage year-round shouldn’t be a luxury, it’s a necessity, and this threshold helps you do just that.

If you’re on a budget, this garage door threshold seal is a must. You’ll wonder how you lived without a dry garage after you’ve had this baby installed for a week or two. Unfortunately, this product doesn’t come with glue but gorilla glue should do the trick.

  • Great budget price
  • Keeps out water during wet season
  • Adhesive not included

M-D Building Products 50100 M-D Single Garage Door Threshold Kit

  • Length: 10 feet

This threshold seal is perfect for small garages. You’ll find that other thresholds seal make you pay for more length that you don’t need, and this deal takes care of that problem.

You won’t have to worry about any snakes, bats, or rats getting into the garage from the door, they’ll have nowhere to go but back from where they came from. It’ll also prevent drafts which is a plus.

Not only that, it’ll keep your garage dry as can be. A dry garage is a safe garage, and without a threshold seal to prevent water from coming inside, you’re putting yourself and others at risk. It’s best to be safe than sorry!

What I like about this model is the adhesive that it provides. For the price, you wouldn’t think they could ship it out with the amount of adhesive that you would need. But think again! You get a tube of adhesive which can be reused after installation.

Installation is the same as the other thresholds, cut and glue. It installs in a jiffy and you’ll have no more water coming into your garage. For a simple package, this threshold sure packs a punch.

  • For small garages
  • Great value
  • Might not be long enough for your needs

Auto Care 10-Foot Garage Door Bottom Seal

  • Length: 10 Feet

This product is perfect for 10′ garage doors and will be a necessity if you want to waterproof your garage.

Installation is easy, remove your old seal. Give the bottom of your garage door a quick cleaning and then get soap and water all along with your new seal. Slide it right in along the track and you’re good to go.

If you have a larger garage, it also goes up to 20 feet. I recommend checking if your garage door takes 1/4 inch ends or 3/8th inch ends. You’re going to want it to fit snug along the tracks, so make sure you get the right size to make your garage is waterproofed.

A seal is going to be necessary alongside your new threshold, otherwise, you may find that your old seal doesn’t quite get waterproof your garage as you’d like. It’s a small investment to make to ensure your garage will be water-free for years to come.

It’s hard to go wrong with this product, reviewers love it and some say installation was easy as heck! Just remember to use some soap and water for installation and you should be set.

  • A must alongside your threshold for a tight seal
  • Perfect for 10 foot garage doors (but can go higher)
  • Installation can be tricky if you don’t use lube or soap/water

DasMarine Garage Door Seal Bottom Rubber

  • Length: 10 Feet
  • Type: 3/8 inch T-End

This garage door bottom seal is an even cheaper solution to getting the perfect seal on your garage from the inside.

If you have WD40, it can help to spray the track once you’ve removed the old seal. You can slide your new one right in and then tuck the sides into the seal. Your garage will now work year-round to keep water, snow, and rain OUTSIDE where it belongs!

What I like about this model is that it has an inner tube which makes for an all-around more solid product. Other models have flimsy innards which can prevent your garage door from being waterproof.

To make your life easier, simply cut open your old seal and trash it. Clean up your garage door and slide this bottom seal into place. You’ll be able to enjoy keeping critters and moisture out of your garage for good!

  • Great budget buy
  • Might be hard to install if you have no lube around
