How to Seal A Garage Door from The Inside

1. Seal the Garage Door Bottom

There are different approaches and methods to use to completely seal the garage door bottom.

I’ll be highlighting all options below, and it’s upon you to decide the one best suited for you.

Threshold Floor Seals

Garage floor seals are perfect for sealing the garage door bottom against pests, weather, and sounds from leaking from the outside.

To install this product, it’s recommended that you mark an outline on the floor where the garage door sits.

Use a marker pen or chalk and avoid using tape as it can interfere with the installation process.

After marking, raise the door and fix the seal on the floor according to the product’s instructions.

You may need to use an epoxy to help create a permanent bond, and you might have to wait for 4-48 hours for the product to fully cure.

Door Bottom Seals

A door bottom seal is attached to the garage door bottom using a strong adhesive for a permanent bond.

Other products will require either screws, nails, or staples for installation.

It’s important to ensure that the garage door is properly cleaned before installation.

This is because debris or dirt can adversely affect the product’s integrity.

Only use nails or screws if you have a wood garage door.

Properly fix the seal to the door bottom according to the manufacturer’s instructions on the product.

After installation, close the door firmly and allow up to 24-48 hours for the product to properly cure.

I would recommend you undertake this activity during the weekend as there’s less movement in the garage during this time.

Alternatively, you can undertake it in the week but ensure you find somewhere else to park your car during this 24-48hrs window period.

Garage Door Brush Strip Seals

Unfortunately, due to moisture, you’ll find that most garage door bottoms in poor conditions.

This makes it impossible to install the bottom seals and threshold floor seals highlighted above.

Therefore, your best bet, in this case, would be to try garage door brush strip seals.

Install the brush strip on the inside bottom side of the garage door following the manufacturer’s instructions.

This method will only prevent rodents and small crawling insects from making their way inside your garage.

Unfortunately, you’ll get no soundproofing benefits as the brushes will splay out, creating some gaps for airborne and impact noise to travel through.

2. Seal the Garage Door Top

Sealing the garage door top will not only block out noise but also keep off those small flying insects and birds.

When the gap at the top of the door isn’t properly sealed, you note that sunlight rays shine through this gap.

Even though weatherstripping products can help seal this gap, I would recommend you to use a product known as garage door top seal.

The product is specifically designed for this purpose and will immediately note an improvement in temperature regulations upon installation.

You may need to allow for up to 72 hours for the top seal to properly cure.

3. Seal Garage Door Sides

Now that we’ve handled the bottom and top sides of your garage door, why not seal the sides.

Gaps on the sides of garage door form with old ages thanks to regular wear and tear due to frequent garage door opening and closing.

Additionally, frame problems and structural shifting can also be major contributors to this problem.

Your best to soundproof garage door sides would involve using weatherstripping.

Weatherstrip is also a popular product when it comes to hollow soundproofing doors or soundproofing dorm rooms.

Final Thoughts on How to Seal A Garage Door From The Inside

Like I’ve always recommended in the past, these are simple DIY hacks you can implement during your own free time.

The trick is to ensure that you’ve properly sealed the entire door- including the sides, bottom, and top.
