Garage door maintenance requires a keen understanding of its components, and the expansion foam at the bottom serves a critical function. It is a sealant that is flexible. The sealant fills the gap. The gap exists between the door and the floor. This weather stripping is important. The weather stripping keeps elements out. Elements include rain and pests. Many homeowners often overlook this small part. This small part significantly impacts energy efficiency.
Okay, picture this: you’re standing in your garage, and a gust of wind whistles right under the door. Brrr! Or maybe you’ve found an uninvited critter or two making their way inside. Not ideal, right? That’s where sealing the bottom of your garage door comes in, and expansion foam can be a real hero in this situation.
Why is sealing that sneaky gap so crucial, you ask? Well, for starters, it’s about saying goodbye to wasted energy. Think of all the money you’re throwing out the window (or, in this case, under the door) because of drafts! Plus, it’s your first line of defense against unwanted guests – from creepy crawlies to furry intruders. And let’s not forget the weather! Sealing keeps out rain, snow, and all that other unpleasantness Mother Nature throws our way, protecting your precious tools, storage, or that vintage car you’re restoring.
Now, you might be thinking, “Okay, I get it, but aren’t there other ways to do this?” Absolutely! You’ve probably heard of trusty rubber seals, simple vinyl seals, and even those fancy brush seals. They all have their perks, but they can also be a bit finicky. Rubber can be tough to install, vinyl might crack when it gets cold, and brushes? Well, they wear down pretty quickly.
That’s where our friend expansion foam struts onto the stage. It’s like the chameleon of sealing solutions, especially when your garage floor isn’t perfectly smooth (and let’s be honest, whose is?). It expands to fill those nooks and crannies, creating a snug fit that keeps the elements out.
So, buckle up, because in this guide, we’re going to dive deep into the world of expansion foam. We’ll show you how to use it safely and effectively, so you can finally say goodbye to drafts, pests, and wasted energy. Let’s get sealing!
Understanding Your Garage Door and Floor: Setting the Stage for a Perfect Seal!
Alright, before we dive headfirst into the foamy goodness of sealing your garage door, let’s take a quick peek at the two main characters in our little play: the garage door itself and the floor it sits on. Think of it like getting to know the actors before the show starts – helps you appreciate the performance, right? Plus, understanding their quirks can save you a ton of headaches (and wasted foam!) down the line.
Garage Door Construction: A Quick Tour
First up, the garage door! You probably see it every day, but have you ever really looked at it? Garage doors aren’t just one big slab of…well, whatever they’re made of. There are a few different types out there, each with its own personality:
- Sectional Doors: These are the most common types, the reliable minivan of garage doors. They’re made up of hinged panels that roll up along tracks. Easy to replace if damaged, sectional garage door is one of the safest and most useful that’s out there
- Roll-Up Doors: Picture a giant window blind, and you’ve got the idea. Roll-up doors coil up into a drum above the opening.
- Single-Panel Doors: These swing out in one piece. Less common these days, but you might still find them hanging around (pun intended!).
For our sealing adventure, the key things to notice are the bottom panel, where the door meets the floor, the threshold (that little bump you might have), and any existing weather stripping. Existing weatherstripping that does not work well, can cause a lot of issues for the garage door. That’s where we’re going to be focusing our attention.
Garage Floor Considerations: Laying the Groundwork (Literally!)
Now, let’s talk about the unsung hero beneath our feet: the garage floor. This is where things can get a little tricky. You can’t go wrong in having a great garage flooring. Just like the garage door, the kind of flooring the garage has will also affect the overall appeal of the garage
- The kind of materials will affect in the adhesion of the expansion foam
- A clean and level garage floor is the key to optimal adhesion.
Here’s the lowdown on common garage floor surfaces:
- Concrete: The classic! But even concrete isn’t perfect. It can be rough, uneven, and prone to cracking.
- Epoxy: This gives you that shiny, showroom-ready look. But epoxy can be a bit slippery, and expansion foam might not stick to it as well without some extra prep work.
- Painted Surfaces: Paint can chip and peel, which means the foam won’t have a solid surface to grab onto.
Before you even think about grabbing that can of expansion foam, take a good hard look at your floor. Are there any cracks or damage? Patch those up first! Think of it like prepping a canvas before you start painting. A smooth, clean, and even surface is essential for the expansion foam to do its job properly. We’ll cover surface prep in detail later. So, understanding your garage door and floor is the best way to seal your door and have the perfect seal.
Expansion Foam: Your Sealing Solution
Alright, let’s dive into the wonderful world of expansion foam! You might be thinking, “Foam? Really? That’s what I’m here for?” Trust me, this stuff is more exciting than it sounds, especially when it comes to banishing those pesky drafts and unwelcome critters from your garage.
What is Expansion Foam?
Simply put, expansion foam is a polyurethane or similar material that comes in a can and magically (okay, chemically) expands when it’s released. Think of it as the superhero of the sealing world. It’s used to fill gaps, cracks, and voids in construction and home improvement projects. From insulating windows and doors to filling holes in walls, it’s the go-to for creating a barrier against air, moisture, and even unwanted guests.
Types of Expansion Foam: Choosing Your Weapon
Now, not all expansion foams are created equal. It’s like choosing the right tool for the job, except the tool is a can of expanding goo. Here’s the lowdown:
Closed-Cell vs. Open-Cell
-
Closed-cell foam is the tough guy of the group. Its cells are, well, closed, which means it’s water-resistant, denser, and has a better insulation value. For your garage door, closed-cell is the way to go because it can handle moisture like a champ. Imagine an elephant never forgets, same with the foam, it stays with door to protect your lovely car.
-
Open-cell foam is more like a sponge. It’s less dense and can absorb water, making it a no-go for garage doors unless you want a soggy surprise every time it rains.
Low-Expansion vs. High-Expansion
- Low-expansion foam is your best friend when sealing a garage door. It expands gently, filling gaps without putting too much pressure on the door. This is crucial because you don’t want to end up with a warped or damaged door.
- High-expansion foam is more for larger voids and might be a bit too enthusiastic for delicate garage door work. Unless you’re trying to lift your garage off its foundation (please don’t), stick with the low-expansion variety.
Advantages and Disadvantages: The Good, the Bad, and the Foamy
Let’s get real about why you might want to use expansion foam and what to watch out for:
-
Pros:
- Effective Sealing: It fills gaps like a boss.
- Insulation: Keeps your garage warmer in the winter and cooler in the summer.
- Conformability: It molds to uneven surfaces like it was born to do it.
- DIY-Friendly: Even if you’re not a pro, you can handle this.
-
Cons:
- Over-Expansion: It can get a little too excited and make a mess.
- Messiness: Wear gloves, folks. This stuff is sticky.
- Removal Difficulty: If you mess up, it can be a pain to remove.
- Limited Lifespan: It won’t last forever, but with proper care, it’ll do the job for a good while.
So, there you have it! Expansion foam is a fantastic option for sealing your garage door, but like any tool, it’s essential to understand its properties and use it correctly.
Preparing for Installation: A Crucial Step
Alright, listen up, DIY warriors! Before you even think about squeezing that can of magical expanding goo, let’s talk prep work. Trust me, this ain’t a step you wanna skip. Think of it like stretching before a marathon, or preheating the oven before baking. It sets you up for success, avoids a giant mess, and ensures that your garage door seal is strong and long-lasting.
Essential Installation Tools: Gear Up!
First things first, gather your arsenal. We’re not talking about needing a whole hardware store, but a few key players are essential:
- Utility Knife: Your trusty blade for trimming excess foam. Make sure it’s sharp! Dull blades and expansion foam don’t mix (unless you like frustration).
- Caulk Gun (if using foam sealant): If you’re going with a caulk-style expansion foam, this is your weapon of choice for even, controlled application. Don’t try squeezing the tube directly; you’ll regret it.
- Measuring Tape: Knowing the size of the gap will save you time, money and help you know how much foam you need to use. Measure twice!
- Wire Brush or Scraper: Old sealant, rust, flaking paint? Banish them! You need a clean surface for that foam to bond properly.
- Vacuum Cleaner: All that scraping and brushing makes a mess, and no one wants to install foam over dusty debris.
- Safety Gear:
- Gloves: Expansion foam is sticky and can be irritating. Protect your hands.
- Safety Glasses: Because nobody looks good with foam in their eyes. Seriously, protect your peepers.
- Respirator Mask (Potentially): Ventilation is key, but if you’re super sensitive or the garage is stuffy, a mask is a smart idea.
Surface Preparation: Cleanliness is Next to Godliness
Okay, gather ’round, because this is the most important part. Think of your garage floor and door bottom as the bride and groom, and the foam is the ring. You want a solid, lasting connection, right? So, prep those surfaces!
- Thorough Cleaning: We’re talking seriously clean. Get rid of all dirt, debris, old sealant remnants, and loose paint. Nothing should be standing between the foam and its bond.
- Dry, Dry, Dry! Water is the enemy of adhesion. Make sure both surfaces are completely dry before you even think about applying the foam.
- Scrub-a-dub-dub: Use that wire brush or scraper to aggressively remove any rust or loose material. Again, you want a pristine surface.
- Primer Power (Optional): If you’re dealing with painted or epoxy-coated floors, consider using a primer or adhesion promoter. This is especially helpful if you’ve had trouble with adhesion in the past. A primer gives the foam something extra to grab onto and helps it stick like glue.
So, take a deep breath, gather your supplies, and get those surfaces squeaky clean. The better the prep work, the better the seal! It’s like the old saying goes (okay, maybe I just made it up), “A clean surface is a sealed surface.” Now go get ’em, tiger!
Step-by-Step Installation Guide: Achieving a Perfect Seal
Okay, you’ve prepped everything, you’ve got your foam, you’re ready to roll. Now for the fun part, let’s get that garage door sealed up tight! Think of this as a relaxing DIY project… with the added bonus of saving money on your energy bill, sounds good right?
Measuring and Cutting: Precision is Key!
First things first, we need to know what we’re working with. Close that garage door tight and get down on your hands and knees to measure the gap between the door and the floor. We aren’t aiming for a sloppy seal, we are aiming for perfection. Get your measuring tape and get ready for action.
Now, grab your expansion foam can. See that nozzle? The manufacturer usually gives you instructions on where to cut it based on how big you want the foam bead to be. Follow those instructions. This is a crucial step because it directly affects how much foam comes out and, consequently, how well your seal will work. Cutting it too big is a nightmare, and too small is a bummer.
Applying the Foam: Steady Does It!
Now for the application. Grab your foam can – or your caulk gun if you’re using expansion foam sealant – and get ready to unleash the magic. Apply the foam in a steady, consistent bead along the bottom edge of the garage door where it meets the floor. Seriously, go slow.
Think of it like icing a cake – except instead of delicious frosting, you’re using expanding goo to keep out the elements. Follow the manufacturer’s recommendations for how thick to make the bead. Too much foam and you risk a giant, unwieldy mess; too little, and you might as well have not bothered. If you are using a caulking gun make sure that you maintain steady pressure. If it is not consistent it can be an issue and make the process much more difficult.
Curing Time and Monitoring: Patience, Young Padawan!
This is where the patience comes in. Once you’ve laid down your bead of foam, resist the urge to mess with it. Now, step away from the garage and let it do its thing.
Manufacturers usually recommend about 24 hours for the foam to fully expand and harden – check the label on your can for specifics. Keep an eye on it during the expansion process. Once the foam is fully cured (and it feels solid to the touch), grab your utility knife and carefully trim any excess.
Finally, give your handiwork a thorough once-over. Are there any gaps? Any uneven areas? If so, don’t fret! Just apply a bit more foam to those spots and repeat the curing process. Yes, it takes time, but trust me, the end result is a perfectly sealed garage door that will keep the weather out and your energy bills down.
Safety First: Don’t Become a Foamzilla!
Okay, let’s be real, expansion foam is pretty cool stuff. It’s like magic in a can, filling gaps and making things cozy. But, just like with any superhero power, with great foam comes great responsibility! We’re not trying to scare you, but this stuff isn’t exactly bubble bath, so let’s talk safety. Think of this section as your “how not to end up on the evening news because of DIY gone wrong” guide.
Open Up and Air It Out: Ventilation is Key!
Imagine being stuck in a tiny room with a skunk… that’s kind of what it’s like breathing in too much expansion foam fumes. Yikes! Seriously though, good ventilation is your best friend here. Throw open that garage door – like, really open – and let the fresh air flow. If you’ve got a fan, now’s its time to shine, point it outwards to help keep those fumes away. Think of it as giving the fumes an eviction notice, if you will.
Suit Up: Protecting Your Precious Bod
Alright, time to gear up! Imagine expansion foam landing on your skin or, even worse, in your eyes. Not a fun mental image, right? That’s why gloves and safety glasses are non-negotiable. Treat them like your superhero armor against the dreaded foam monster. And, if you’re feeling extra cautious (or your garage ventilation is questionable), a respirator mask is a solid investment. Your lungs will thank you!
Chemical Handling 101: Read Before You Spray!
That can of expansion foam isn’t just a decoration; it’s got a whole bunch of important information on it. Yes, I know reading instructions is boring, but trust me, your future self will appreciate it. Read the manufacturer’s instructions carefully, paying attention to safety guidelines. And when you’re done with the foam, dispose of it properly. Don’t just toss it in the neighbor’s recycling bin!
Finally, and this is super important, keep that foam away from children and pets. They might think it’s a fun toy, but it’s definitely not. Treat it like you would any other potentially hazardous chemical – store it safely out of reach.
Basically, a little common sense and precaution goes a long way. Stay safe, have fun, and may your garage door sealing adventures be epic (and fume-free)!
Troubleshooting Common Issues
Okay, so you’ve tackled sealing your garage door with expansion foam – awesome! But what happens when things don’t go exactly as planned? Don’t sweat it; even the best DIY projects can hit a snag. Let’s troubleshoot some common issues and get your garage door sealing back on track.
Improper Expansion: Uh Oh, Did My Foam Go a Little Wild?
Ever seen expansion foam turn into, well, too much foam? It’s like it has a mind of its own! This usually happens for a few reasons. First, you might’ve been a little too generous with the application (we’ve all been there). Second, using the wrong type of foam can cause it to over-expand. And finally, temperature can play a role. Extreme heat can make the foam expand more than it should.
What to do? Grab a sharp utility knife and carefully trim the excess foam. This is where patience is key! Next time, opt for a low-expansion foam, which is less likely to go all “Hulk” on you. And finally, check the manufacturer’s instructions for the ideal temperature range before you start spraying.
Cracking or Peeling: When Your Seal Starts to Fall Apart
There’s nothing more disheartening than seeing your brand-new seal start to crack or peel. Bummer, right? Luckily, it’s often preventable! This issue usually stems from poor surface preparation. If the garage floor or door wasn’t properly cleaned, the foam won’t adhere well.
The fix? Preventative measures are your best bet. Before applying the foam, make sure to thoroughly clean both surfaces. Consider using a primer to give the foam something extra to grip onto. Also, avoid applying foam in extreme weather. If the damage is already done, don’t worry! Just remove the loose foam, clean the area, and reapply a fresh bead.
Moisture Problems: Keeping Water Where It Belongs (Outside!)
Moisture and garages aren’t exactly a match made in heaven. If water starts creeping in through your newly sealed garage door, that can be a sign for something wrong.
How to protect against Moisture? The fix is to use closed-cell foam, which is naturally water-resistant. Make sure there’s proper drainage around your garage door to prevent water from pooling. If you’re extra cautious, apply a waterproof sealant over the foam for added protection.
Expansion Foam vs. the Competition: Finding Your Garage Door’s Soulmate
So, you’re on a quest to banish drafts and unwanted critters from your garage, eh? You’ve heard whispers of expansion foam, but the hardware store aisles are a jungle of sealing solutions! Rubber, vinyl, brushes… it’s enough to make your head spin. Let’s break down the contenders, shall we? Think of it like a dating show, but for garage door seals. Who will get that final rose… err, airtight seal?
The Seasoned Veteran: Rubber Seals
These guys are the OGs of garage door sealing. Durable and built to last, they’re like that reliable friend who always shows up. But, and this is a big but, they’re a bit rigid. If your garage floor resembles the surface of the moon more than a smooth landing strip, rubber seals might struggle to conform. Installation can also be a bit of a wrestling match, especially if you’re not a seasoned DIYer.
The Budget-Friendly Charmer: Vinyl Seals
Ah, vinyl! Easy on the wallet and a breeze to install – the “life of the party”! These seals are typically inexpensive, but think of them as fast fashion of the sealing world. They look good, but they aren’t in it for the long haul. They can become brittle and crack in cold weather, leaving you with gaps quicker than you think!
The Quirky One: Brush Seals
Brush seals are those characters with an edge, who would do the most unexpected things! Their flexibility is their superpower, making them ideal for uneven surfaces and, their soft bristles excel at blocking out pests. However, when it comes to locking out the elements? Well, they are not the best one to get that job done. They will wear out faster than the rest, especially if your garage door sees a lot of action.
And the Winner Is… (Maybe): When Expansion Foam Steals the Show
Okay, so when does expansion foam take the crown?
- Uneven Garage Floors: Remember that moon-like surface we mentioned? Expansion foam doesn’t flinch. It conforms to every nook and cranny, creating a truly airtight seal.
- Large Gaps: Got a Grand Canyon-sized gap under your door? Foam can fill it. Other seals might struggle, but foam expands to get the job done.
- Sealing and Insulation in One: Want to kill two birds with one stone? Expansion foam provides both sealing and insulation benefits, helping to keep your garage warmer in the winter and cooler in the summer. This will save you money over time!
Ultimately, the best choice depends on your specific situation. But if you’re dealing with imperfections, seeking maximum sealing power, and want a bit of extra insulation, expansion foam might just be your garage door’s perfect match.
How Weather Affects Expansion Foam
Okay, let’s get real about weather. Ever tried to build a sandcastle during a hurricane? Probably not the best idea, right? Same goes for expansion foam. Temperature is key here. Think Goldilocks – not too hot, not too cold, but just right. Ideal temperature ranges are typically specified by the manufacturer (so, yeah, read the instructions – I know, nobody likes to, but trust me). Applying this stuff in freezing temps or blazing heat? You’re asking for trouble. It might not expand properly, or worse, it could crack or crumble down the line. That’s no fun.
And then there’s humidity, that sneaky little devil. Picture this: you’re trying to bake a cake on a super humid day. Everything gets sticky, right? Well, high humidity can mess with the curing time of your expansion foam. It might take longer to fully harden, and that can be a pain. Be patient!
Protecting Against Moisture
Listen up, folks, because moisture is the arch-nemesis of, well, pretty much everything that’s supposed to stay dry. When it comes to your garage door seal, moisture can cause all sorts of problems, from mold and mildew to straight-up deterioration of the foam. Your best defense?
First, make sure you’re using closed-cell foam. Remember those science classes where you learned about cells? Well, closed-cell foam has, you guessed it, closed cells, which makes it way more water-resistant than its open-cell cousin.
Next, think about putting on a raincoat – for your foam! A waterproof sealant applied over the foam gives it an extra layer of protection from the elements. Think of it as a spa day for your garage door seal!
And finally, address any drainage issues around your garage door. If water is pooling around the base of the door, it’s only a matter of time before it finds its way into your seal. Make sure your gutters are clear and that the ground slopes away from the garage. You can also consider installing a French drain to redirect water away from the foundation.
Beyond Sealing: It’s Like a Cozy Blanket and a Bouncer for Bugs!
Okay, so you’ve got this expansion foam all set to block out the drafts. Awesome! But guess what? It’s not just about stopping the wind from whipping through your garage. This stuff’s got hidden talents – like being a mini-insulation superhero and a bouncer at the entrance to your bug club (which, let’s be honest, nobody wants to be a member of).
Think of it this way: Your garage door is like a giant, slightly leaky window. Sealing it is like finally putting on that extra layer when you’re watching the game on a chilly Sunday.
Insulation Power: Saving You Money and Keeping You Comfy
Let’s talk about energy efficiency, which is just a fancy way of saying “saving money on your utility bills.” Expansion foam helps by acting as a barrier against heat loss in the winter and heat gain in the summer. Basically, it’s like giving your garage a cozy blanket.
When you think about the R-value of insulation, its resistance to the flow of heat, expansion foam can give you a modest but noticeable boost. It’s not going to turn your garage into a polar bear’s den or a desert oasis, but it will definitely help keep the temperature more stable. Plus, less air sneaking in means your heating and cooling systems don’t have to work as hard. Cha-ching!
Pest Control: Keep the Critters Out!
Nobody wants unwanted guests at their garage party (especially the ones that scurry, crawl, or have too many legs). Sealing those sneaky gaps is like hiring a tiny, foam-based security guard to keep those pests out.
Sealing all those cracks and crevices is like putting up a “No Trespassing” sign with extra emphasis. Make sure you get all the potential entry points! This can include the sides of the door, any gaps around pipes, or even little cracks in the foundation. Think of your garage as a fortress, and expansion foam is the mortar holding it all together!
Achieving Optimal Adhesion: Tips and Tricks
Ever tried sticking two things together and ended up with a frustrating mess? Yeah, adhesion can be a real pain, especially when you’re dealing with something as important as sealing your garage door! Let’s make sure that expansion foam sticks around (pun intended!).
Surface Compatibility: The “Match Made in Heaven” Concept
Think of your garage floor and expansion foam as potential partners. You wouldn’t set up just anyone on a blind date, right? The same logic applies here!
- Play Nice Together: Not all surfaces are created equal. Some materials are naturally more adhesive-friendly than others. Bare concrete? Usually pretty good. Super-slick epoxy? Not so much. Making sure they’re compatible is key.
- The Secret Test: Before you go all-in, do a test run! Find a small, hidden spot—maybe a corner of the garage floor or the inside of the door—and apply a dab of foam. Let it cure completely. Now, give it a gentle tug. If it peels away easily, Houston, we have a problem! This leads us nicely to our next point…
Pre-Treatment: Giving Adhesion a Helping Hand
Sometimes, even the best matches need a little push in the right direction. That’s where pre-treatment comes in. Think of it as playing cupid for your foam and your garage surfaces!
- Primer Power: Primers are like magic potions. They create a better bonding surface, especially on tricky materials like painted or epoxy-coated floors. They essentially act as a double-sided tape for your expansion foam. They promote adhesion!
- Primer Recommendations: When choosing a primer, look for ones specifically designed for concrete or masonry. Epoxy primers are your best bet for epoxy floors! Read the product labels carefully to ensure compatibility with both your floor type and the expansion foam. Follow the application instructions precisely. A little extra effort here can make a world of difference in the long run. It’s really important to get it right!
Maintenance and Longevity: Keeping Your Seal Intact
Alright, you’ve gone through all the effort of sealing that garage door, congrats! But just like that shiny new car, your expansion foam seal needs a little TLC to keep it doing its job. Think of it as preventative medicine for your garage – a little effort now saves you a headache (and a higher energy bill) later!
Cleaning: A Little Soap and Water Go a Long Way
Listen, who actually enjoys cleaning? Probably no one. But a clean seal is a happy seal! Regularly give your expansion foam a gentle scrub with a mild detergent and water. This gets rid of all the grime, dirt, and leaves that like to accumulate. Trust me, this isn’t just about appearances; a clean surface allows you to spot potential problems early on. Plus, think of all the extra sunshine you’re letting into your garage. Okay, maybe not, but it’s still worth doing!
Inspection: Be a Seal Sherlock
Become a seal detective! Regularly inspect your expansion foam for signs of wear and tear. Look for:
- Cracks: Are there any splits or fissures forming?
- Peeling: Is the foam starting to detach from the door or floor?
- Damage: Any noticeable chunks missing? Maybe your neighbor’s cat tried to use it as a scratching post!
- Discoloration: Are there visible mold or mildew spores.
Early detection is key! A small crack can turn into a big problem if left unattended. The quicker you notice a problem and address it, the better!
Replacement: When It’s Time to Say Goodbye
Sadly, nothing lasts forever, not even your meticulously installed expansion foam seal. Eventually, it will need replacing. Here’s when you’ll know it’s time:
- Significant Damage: If the foam is severely cracked, peeled, or otherwise damaged, it’s not doing its job anymore.
- Loss of Adhesion: If the foam is constantly detaching from the door or floor, even after cleaning, it’s time to let go.
- Reduced Effectiveness: If you’re noticing drafts, pests, or water entering the garage despite the seal, it’s probably time for a replacement.
So, how do you perform this delicate surgery? Here’s a quick guide:
- Remove the Old Foam: Use a utility knife to carefully cut away the old foam. A scraper can help remove stubborn bits.
- Clean the Surface: Thoroughly clean the area where the new foam will be applied. Remove any residue, dirt, or old adhesive.
- Reapply New Foam: Follow the installation instructions from Section 5 to apply new expansion foam.
The bottom line? A little maintenance will keep your garage door sealed, your energy bills lower, and those pesky critters out where they belong! Now, go forth and conquer that garage seal game.
So, next time you’re tidying up the garage and notice that funky foam at the bottom of your door, don’t panic! A little inspection and maybe a quick replacement can save you from unwanted critters and keep your garage cozy. Happy DIY-ing!
