Are you a Lego enthusiast who’s constantly grappling with the question of where to store your ever-growing collection? Have you ever wondered if the attic or garage is the best place to stash your precious plastic bricks, but can’t seem to find a definitive answer?

Well, you don’t have to worry anymore, because we’re about to delve into the world of Lego storage and reveal the unbelievable secrets that will help you make the best decision for your collection! Prepare to have your mind blown as we explore the ins and outs of ideal storage locations, temperatures, and conditions for preserving your Lego sets.

So first things first, should you store your Legos in your attic or inside your garage?

It is not recommended to store Legos in the attic due to the high temperatures that can cause the bricks to warp or meld together over time.

Storing them in a garage is generally fine, as long as it is not damp or too hot. However, it’s important to note that not all garages are the same, so the suitability of storing Legos in a garage depends on factors such as location and the type of garage you have.

Dumping Lego sets in the attic or in boxes in the garage is not a good idea. Summer heat can discolor the bricks and potentially affect the shape of some pieces, making them unusable. Additionally, dust and grime can be challenging to clean off Lego pieces, so it’s best to store them in lidded boxes to protect them

If necessary, Legos can be stored in Sterilite or Rubbermaid bins, as long as they are kept away from direct sunlight or extreme heat/cold. Legos are made of ABS (Acrylonitrile Butadiene Styrene), which is the same material used in plumbing drains and other products, so they can withstand normal storage conditions but extreme temps or sunlight can cause those Legos to start to discolor or even turn a little bit yellow.

In the rest of this article, I will go into more detail about where you should store Legos as well as the ideal conditions to store them in. So, buckle up, grab a cup of your favorite beverage, and let’s get this Lego party started!

Why Storing Conditions Matter for Legos

When I first started collecting Legos, I didn’t think much about how or where to store them. But boy, did that change when I stumbled upon the effects of temperature, humidity, and other factors on my beloved bricks!

Let me tell you, the impact of these variables is nothing to sneeze at. In this section, we’ll dive into the nitty-gritty of why proper storage conditions are crucial for maintaining the integrity and value of your Lego sets.

Temperature and humidity effects on Lego bricks

Did you know that extreme temperatures and humidity levels can wreak havoc on your Legos? When I found this out, I was shocked!

High temperatures can cause your bricks to become soft and warped, while low temperatures can make them brittle and susceptible to breakage. Humidity is another villain in the story of Lego preservation: too much moisture in the air can lead to mold and mildew growth, while too little can cause the bricks to become dry and brittle.

It’s a delicate balancing act, but don’t worry—we’ll guide you through the process of creating the perfect storage environment for your collection.

Color fading and brittleness

Imagine spending hours assembling a magnificent Lego set, only to have its colors fade and its bricks turn brittle over time. What a heartbreak! But this sad scenario can become a reality if you don’t store your Legos properly.

Exposure to sunlight and fluctuating temperatures can cause the vibrant colors of your bricks to fade, while brittleness can occur when the plastic material breaks down due to extreme conditions. We’ll discuss tips and tricks to prevent these issues and keep your Lego sets looking their best for years to come.

Cleanliness and Lego value

As a Lego collector, you want to ensure that your sets maintain their value, right? Well, cleanliness plays a significant role in this equation. When I discovered that dirty, dusty, or sticky bricks could decrease the value of my collection, I knew I had to step up my storage game.

In the following sections, we’ll share some expert advice on how to keep your Legos spick-and-span and protect your investment.

The Pros and Cons of Storing Legos in the Attic

So, is the attic the ultimate Lego storage haven? In my quest to answer this question, I uncovered both the benefits and drawbacks of stashing your collection in this often-neglected space.

Let’s weigh the pros and cons, so you can decide if the attic is the right fit for your Legos.

Benefits of attic storage

The attic offers several advantages when it comes to storing your Lego sets. First off, its secluded location means there’s less foot traffic, reducing the risk of accidents and damage.

Plus, with a little creativity and organization, you can transform your attic into a Lego storage paradise! Some of the benefits I found from using my attic for Lego storage include:

  • Reduced foot traffic: Your attic is likely not a high-traffic area in your home, which means fewer chances for accidents that could harm your Lego sets. The attic offers a safe haven where your collection can remain undisturbed and protected.
  • Potential for organization: With the right storage solutions and a bit of elbow grease, you can turn your attic into a Lego collector’s dream! From shelves to bins, the possibilities are endless for creating a well-organized space to house your bricks.

Drawbacks of attic storage

Unfortunately, the attic isn’t all sunshine and rainbows when it comes to Lego storage. There are some cons to consider before deciding if it’s the best location for your collection.

Here are a few potential issues I’ve encountered with attic storage:

  • Temperature fluctuations: Attics can experience extreme temperature changes, particularly if they’re not well-insulated. This can be a major concern, as we’ve discussed the impact of temperature on Lego bricks.
  • Pest issues: In many homes, attics can be a breeding ground for pests like insects and rodents. These unwelcome guests can damage your Lego sets and decrease their value.

Tips for mitigating attic storage issues

Despite the drawbacks, you can still make your attic work as a Lego storage space by taking some precautions. Here are some tips I’ve found helpful:

  • Improve insulation: Proper insulation can help regulate attic temperatures and protect your Legos from extreme conditions. Consider investing in insulation materials to create a more stable environment for your collection.
  • Pest control: Regular pest control measures, such as sealing entry points and using traps or repellents, can help keep unwanted critters at bay and safeguard your Lego sets from damage.

The Pros and Cons of Storing Legos in the Garage

Now, let’s turn our attention to the garage. Is it a better option for storing your Lego sets compared to the attic? Let’s explore the pros and cons of this often-overlooked storage space.

Advantages of garage storage

The garage has its fair share of benefits when it comes to Lego storage. Here are a few highlights that caught my attention:

  • Easy access: Unlike the attic, the garage is typically more accessible, making it easier to retrieve and organize your Lego sets whenever you want.
  • Spaciousness: Garages often provide ample space for storage, giving you plenty of room to house your growing Lego collection.

Disadvantages of garage storage

As with the attic, the garage has some potential downsides that you should be aware of before stashing your Legos there. Here are a couple of concerns I’ve discovered:

  • Humidity: Depending on your location, garages can be susceptible to high humidity levels, which, as we’ve discussed, can harm your Lego bricks.
  • Potential for damage: Garages are often used for various purposes, such as parking vehicles and storing tools. This multipurpose nature can increase the risk of accidents and damage to your Lego sets.
  • Extreme temps: If your garage is detached it will often have close to the same temps as the outside air. Those extreme temperatures can seriously damage your Legos making garages like this a poor storage location.

Improving garage storage conditions

Don’t let the drawbacks deter you! With some planning and effort, you can make your garage a safe and suitable storage space for your Legos. Here are a few suggestions:

  • Dehumidifiers: Investing in a dehumidifier can help regulate humidity levels in your garage, protecting your Lego sets from moisture-related issues.
  • Shelving and storage solutions: Opt for sturdy shelves and storage containers to keep your Lego sets organized and shielded from potential damage in the garage.

Ideal Temperature and Humidity Conditions for Legos

Now that we’ve discussed the pros and cons of storing Legos in the attic and garage, let’s dive into the ideal temperature and humidity conditions for preserving your precious plastic bricks.

Optimal temperature range

Lego bricks are made from ABS (acrylonitrile butadiene styrene) plastic, which has specific temperature tolerances. To ensure your Lego sets remain in tip-top shape, aim to store them within the following temperature range:

  • Ideal Temperature: 68°F – 77°F (20°C – 25°C)

Storing your Legos within these temperature limits can help prevent warping, brittleness, and other temperature-induced damage.

Ideal humidity levels

As we’ve discussed, humidity plays a critical role in maintaining the integrity of your Lego sets. To prevent issues such as mold growth and brittleness, strive to maintain the following humidity levels in your storage space:

  • Optimal Humidity: 40% – 50% Relative Humidity (RH)
  • Acceptable Range: 30% – 60% RH

By keeping the humidity within these ranges, you can create a favorable environment that will help preserve your Lego sets for years to come.

Creative Storage Solutions for Your Lego Collection

Whether you choose the attic, garage, or another space to store your Lego sets, implementing creative storage solutions can make a world of difference in keeping your collection organized and protected.

Here are some inventive ideas I’ve discovered that might inspire you:

Shelving systems

A well-designed shelving system can be a game-changer when it comes to organizing your Lego sets. Consider adjustable shelves, which can be easily reconfigured to accommodate sets of varying sizes.

Don’t forget to add clear labels for easy identification!

Storage bins and containers

Invest in durable, stackable storage bins to keep your Lego sets neat and tidy. Look for bins with tight-fitting lids to keep dust and pests at bay.

Opt for clear containers so you can quickly locate specific sets without having to rummage through multiple bins.

Display cases

For those extra-special Lego sets that deserve a spot in the limelight, consider investing in display cases. Not only do they showcase your prized creations, but they also offer added protection from dust and potential damage.
