It’s made of black rubber, with T-shaped ends that slot into the grooves on the bottom of the door. Your door track will need to have T-ends of at least 0.75 inches for it to fit. The easiest way to check is to pull out your old seal and measure the ends.
The strip is 20 feet long, and you can choose between 2.75 and 3.75-inch widths. That measurement is the distance between T-ends with the strip laid flat. If your floor is uneven, go for the longer width. That will have enough give to conform to the shape of the ground.
It’s easy to cut to the correct size, allowing a perfect fit, even if your door isn’t a standard width.
Because of the T-shaped profile, you’ll simply be able to slide this in place. There’s no need for nails or screws, though you will benefit from silicone spray to help get it into position. It’s still a quicker job than getting out the hammer. And you won’t be left with holes in your door when it’s time to replace the seal.
This will fit a wide range of domestic and light commercial garage doors. If your garage door is made by Amarr, Arm-R-Lite, Costco, Clopay, CHI, Deldon or DCBI, chances are, it will fit. Ditto Gadco, Martin, Safeway, Richard Wilcox and Raynor.
But do take care to measure first. Older garage doors may have much bigger T-slots. If that’s the case with your door, the strip won’t stay put.
Once in place, the heavy-duty rubber will keep out dirt and debris. And although it’s not as thick as some options, it will stay flexible, even in extreme temperatures. It’s rated to cope with anything from minus 40 to 140 degrees Fahrenheit.
It’s long lasting too. It should give you several years of service before needing to be replaced.
Easy to install without screws or nails
Stays flexible for a snug seal, even in extreme temperatures
Choice of two different widths
You’ll need a garage door with the right sized track for it to fit
2. M-D Building Products Vinyl Garage Door Top and Sides Seal
This vinyl door strip from MD-Building Products offers a cost-effective solution for sealing your garage door. It will work on both the sides and top of your door. And its 30-feet of strip costs less than HOOIMA’s 20-foot bottom seal offering. So what do you get for your money?
Well, the white finish is clean and fresh, though it will show up any dirt. There are no T-ends here, so you won’t need to worry about whether your door track is the right size. But it does mean that you’ll need to fix it in place with fasteners, which are included in the pack.
The fasteners that come with the strip may not be to everyone’s taste. They’re basically roofing nails, and they won’t give the most attractive finish. Replace them with smaller nails or wood screws for a neater look. Or if you have one, an electric staple gun will produce a smarter finish in a fraction of the time.
The seal comes on a roll, which means you’ll need to flatten it out before use. It’s worth taking the time to do this properly, and the easiest way is with a heat gun. If you don’t do this first, the seal won’t be flush with the sides and bottom of your door. It won’t look neat and it won’t work as effectively.
If you’re prepared to spend a little time on this extra preparation, this seal will give you excellent results at a keen price. It’s good and thick, so it will keep out bugs, dirt and moisture. And it will stay flexible in low temperatures, so the seal will remain tight.
Clopay’s seal is designed to go on the bottom of your garage door. It’s exactly 18 feet long – so if you have a standard double garage, you won’t need to cut it at all.
It’s four inches wide when laid flat on the floor. It’s designed for a one-channel track. Two L-shaped end pieces form a “T” shape when the strip is bent into a circle. The groove in the middle of each “L” is 1/16th-inch wide, and the whole end piece is 5/16th-inch wide.
To use it, you simply bend the strip so that the two end pieces are back to back. The profile view will be a circle with a T-shape at the join.
Then slide the rubber end pieces into the groove on your door track. If you have a single-channel Clopay garage door, this will fit perfectly. Use some silicone spray and it will slide in more easily.
It doesn’t take long to do, and you won’t have to worry about nails or screws. The only issue you may face is holding the ends of the rubber together to fit them into the groove. We hear wildly different reports of how easy this is to do.
Some people have said the whole installation has taken them no more than 15 minutes. Others have found it impossible to fit the seal into their track and have given up altogether.
There’s no reason this should be anything but straightforward if you’re installing it on the right kind of door. Remember: what you need here is a single channel Clopay garage door! If you’ve got a different design, don’t try to make this fit. It will be a time-consuming process, and probably won’t work.
Once it’s installed, you’ll have an effective seal for your garage door. The rubber is plenty thick enough to withstand the extra wear and tear borne by the bottom of the door. And you won’t need to worry about debris, dirt or creepy-crawlies making their way inside.
This rubber seal from Loobani is designed to go on the bottom of garage doors with double T-shaped channels. It comes in a 20-foot length and is 3.75 inches wide. The width is measured between the two edges when the rubber is laid out flat.
That width should be enough for most garage doors. The exception will be if your door has a track that’s wider than two inches. If that’s the case, you’ll find it better to choose a wider seal. Look for 4.75-inch wide options for a better result.
The T-shaped ends are each 5/16th-inch wide. The rubber is thick enough that you won’t have to worry about damage as you pull it along the track. And you won’t need any screws or nails to fix it in place.
To install it, you simply fold the rubber in half along its length. Then insert one T-shaped piece into each groove.
One thing to note is that the rubber here is thicker than on some other seals – about 1/8th-inch. That means it’s good and durable, and provides excellent insulation. But it’s not as light or easy to install as some other seals on the market.
Make your life easier by spraying the track generously with lubricant to help it on its way. And for wider garage doors in particular, you’ll find the process easier if you can get a friend to help.
The rubber construction means this is a seal that’s both flexible and weatherproof. It will stay malleable at temperatures between minus 40 and 140 degrees Fahrenheit. And you won’t need to worry about it freezing to the ground.
It’s particularly good at acoustic insulation. The seven round layers of insulation can reduce noise transmission through your door by as much as five times. If you keep your drumkit in the garage – or have neighbors with a drumkit of their own! – it’s a good option. And it will keep the cold and heat at bay too.
Heavyweight rubber construction is strong and long-lasting
Excellent acoustic insulation properties
Works well between minus 40 and 140 degrees Fahrenheit
Heavier weight means you’ll benefit from lubricant and an extra pair of hands during installation
Won’t be big enough if your door track is more than 2 inches wide.
5. Auto Care Products ProSeal Garage Door Seal Bottom (Our Top Pick)
This seal from Auto Care Products is another one designed to go on the bottom of your garage door. It’s available in either 10 or 20-foot lengths. That will give you a little extra room to maneuver for a neat fit. You may, though, need to trim or fold the ends when it’s in place.
The T-shaped ends are designed to fit a double-channel track. You have a choice of T-end size too – either ¼-inch or 3/8th-inch. That will give you plenty of flexibility to get the right fit.
Installation is easy, particularly with the assistance of a lubricant spray and a friend! You won’t need a hammer and nails, and you won’t have to put holes in your door.
When laid flat, the strip measures 3.5 inches wide. That’s not as big as some seals. If you have a wider track or a very uneven floor, it won’t be the best option.
This one is made of PVC rather than rubber. The advantage of this is that it’s very soft and pliable. And it will cope effectively with cold temperatures without becoming brittle.
The downside is that it’s not as thick as some rubber seals. And it’s not as good at conforming to any irregular dips or bumps in the ground. You may find that you need to fill the gaps by hand using epoxy resin or similar to get effective insulation.
But if your garage floor is fairly even and you have a narrower track, this is a good, economical choice.
Available in choice of lengths and different T-end sizes
Soft and pliable, even in cold temperatures
Not the thickest seal out there
5-inch width means this won’t be the right choice for wider door tracks.
Wayne Dalton garage doors have a distinctive design. If that’s what you have, buy a seal designed specifically to fit. This one is made by the Wayne Dalton factory, so you can be confident they know what they’re doing.
Before you order, just make sure that you have a model that will work with this seal. Not all Wayne Dalton doors are exactly the same either!
The track needs to be one with bead-style channels. Other Wayne Dalton doors have tracks which need T-shaped or bulb-shaped end pieces.
This seal is designed to fit steel garage doors from the Wayne Dalton 8000 or 9000 series. If you have a Thermawayne, Thermaguard or Foamcore style door, this will work just fine.
It’s made of vinyl and comes in a range of different lengths. Choose between 8, 9, 12, 14, 16 and 18-foot options. The range of options means there’s no need to spend money buying more than you need.
Whatever size you order, you’ll get 2 inches extra. That’s designed to ensure you can trim it for an exact fit. And it means there’ll be no gap at either end for dust, cold or pests to get in.
We’ve heard some complaints that the rubber here isn’t quite as thick as older seals. On the plus side, this means it’s more flexible.
Installation is fairly simple. The slide-in design means you won’t have to use a hammer and nails. And your door will stay hole-free.
But as with most seals of this type, you’ll find the process much easier if you lubricate the track first. Silicone spray works well. And if you’re installing it on a cold day, soak the rubber in hot water first. It will make it much easier to maneuver.
The real advantage of this one is that if you match it to your door properly, you’ll get a great fit. The main drawback is that if you don’t have the right door, it will be a waste of money. So check your door specifications carefully before buying.
And if you’re still in any doubt, remove the old seal. Take it to the shop to match it to a new one, or if you’re buying online, compare it to photos. If the end pieces look the same, you should be ok.
Provides a perfect fit for Wayne Dalton 8000 and 9000 series steel doors
Wide choice of different lengths
If you don’t have a Wayne Dalton 8000 or 9000 steel door, this won’t fit
The rubber here isn’t as thick as some other seals.
7. Frost King G16H Nail-On Garage Door Rubber Seal
If your garage door doesn’t have a track, and you don’t want to buy one, slide-in seals won’t work. Instead, you’ll need one you can nail in place. This one from Frost King is a great option.
It comes in lengths of 16 feet and it’s 2.25 inches wide. That will be sufficient to cover a gap of about 1.25 inches between your door and the ground.
The package includes a set of large headed 1.25-inch nails to fix the seal to the door. They’re made of stainless steel, so you won’t have to worry about them rusting. There are enough in each pack to fit the whole seal when positioned at 3-inch intervals.
If you prefer, you can use a pneumatic staple gun to hold the seal in place. That will make very short work of installation and will secure it just as effectively.
And unlike some nail-on seals, there’s no need to glue this in place as well. The rubber is thick enough to stay neatly in place all along the width of the door.
The material here is a thin layer of vinyl over a medium-density foam. It’s very easy to install, but it won’t have the longevity of hard rubber seals. That said, this is a very economical purchase. Even if you find yourself needing to replace it in a couple of years, it will still be a cost-effective buy.
And the softer material means that it’s very flexible. It will mold itself well to uneven floors, keeping out dirt, moisture and wildlife.
Suitable for wooden garage doors and those without tracks
Simple to install
Flexible material molds well to uneven surfaces
Foam core isn’t as durable as hard rubber seals
If you don’t have an electric staple gun, you’ll need to spend time hammering in nails.
If you’re still wondering which is the best seal for your garage door, keep reading! We’re going to take you through some questions to consider before you make your selection.
Top, bottom or sides?
To start with, decide which parts of your garage door you want to seal. Different products are available to seal the top, sides and bottom of the door.
And don’t get confused between a bottom seal and a door threshold. The threshold sits on the garage floor and is a different product altogether. A seal attaches to the bottom of the door itself.
Does your garage door have a track?
If you’re going to seal the bottom of your garage door, you have two main options. You can buy a seal that will slide into grooves on a track. Alternatively, you can choose a seal you nail into place.
Nail-on seals are usually used for wooden garage doors. They’re simple to install, but you will have to spend time hammering in the nails. Alternatively, an electric staple gun works well and is much quicker.
If your door has a track, you can avoid the nails altogether. Make sure you buy a seal with the right shaped end-pieces to fit into the channel. And check whether you need a seal for a single or double-channel track. The easiest way to find out is usually just to look at the seal that’s already in place.
If your door doesn’t have a track, but you can’t face another season of pulling out nails, filling holes and hammering in new ones – don’t despair. It’s possible to purchase a track separately. They’re not expensive, and future seal replacements will be far quicker.
Finally, make sure you buy a seal that’s large enough for your door. There are two main things to think about here.
The most obvious is to ensure the seal will cover the full width or height of your door. Measure carefully at least twice to make sure you’ve got the right dimensions.
The other thing to check is the width of the seal. For seals at the bottom of garage doors, you need there to be enough material to cover the gap fully.
For slide-in seals, check the width of your track too. The wider it is, the more seal will be required to stretch between the channels. For tracks over 2 inches wide, look for seals at least 4.75 inches wide for a good fit.
