If you spend a lot of time in your garage during the winter or summer, the extreme temperatures can make the space colder or warmer than is comfortable. Additionally, if your garage is attached to your home, you may be losing money as heated or cooled air escapes through the garage door. Not only does no one like letting money slip right out of their hands, but working in frigid or sweltering conditions makes any job harder to complete. Luckily, there are ways to weatherproof your garage door, allowing the outside cold or hot air to stay where it belongs. In many cases, homeowners can handle these projects on their own.

Most only require basic supplies and tools, and maybe some help from a trusted friend or family member. Here’s what you need to know. To completely weatherproof your garage door, you’ll actually complete three smaller projects along the way. Each can be done separately or, in many cases, the entirety of the work can be managed in an afternoon. The first part of the larger project involves insulating the garage door itself. Insulating the garage door helps ensure they are more airtight than before. This prevents cold or hot air from coming in by creating a more substantial barrier between the interior of your garage and the outside.

If your garage is too cold in the winter and too hot in the summer, you may think your only option for relief is to purchase a new energy-efficient insulated garage door. While this is certainly a workable solution, it can easily run you more than $1,000 if you have a two-car garage, making it an expense many households can’t shoulder.

Luckily, there is a more cost-effective method for insulating your garage door. Often, by doing the job yourself, you can end up spending only about $200 in materials. Plus, it should only take you an afternoon to get the job done. Here’s what you need to do to insulate a garage door yourself. To completely insulate your garage door against the elements, you’ll ultimately end up completing three smaller projects. This means you can divide up the work into chunks based on your available time or complete the entire project in just an afternoon. The first mini project in the series involves insulating the surface of your garage door.

Unless you live in an especially temperate climate, you likely spend a decent amount on heating and cooling. And, if your garage is attached to your home, money could be slipping right through your hands and exiting through the gaps in your garage door seal. No one likes losing money, especially in higher utility costs, making it imperative you replace the seal whenever it shows signs of significant wear and gaps begin to form.

Luckily, replacing a garage door seal isn’t complicated, and most homeowners can accomplish the tasks with just a few supplies and a little bit of time. Here’s how to handle the process.
