Behind the Door: Exploring the Pros and Cons of Installing a ‘Man Door’ in Your Garage Door

Exploring the Pros and Cons of Installing a ‘Man Door’ in Your Garage Door

As a homeowner, you probably want your garage to be more than just a place to park your car or store your belongings. In fact, many homeowners transform their garages into a workshop, a gym, or even an extra living space. But with this increased utility, you also need more convenience and accessibility.

Enter a man door!

A man door, also called a pedestrian or walk-through door, is a smaller door designed within your main garage door. It provides easy access without having to open the entire door. Besides being a quick entry and exit point, it also improves ventilation and increases natural light. But, like any modification, it also has its drawbacks.

Let’s explore the pros and cons of installing a garage door with a man door.

Pros of Installing a ‘Man Door’

Let’s begin by discussing the advantages of having a man door for garage:

1. Easy Access: 

One of the significant benefits of installing a man door is the easy access it provides. Traditional garage doors require you to lift or roll up the entire door to enter or exit. But a man door offers a smaller, more convenient entry point, specifically designed for individuals. This means you can simply use the smaller man door, saving time and effort.

2. Increased Functionality:

3. Energy Efficiency:

Installing a man door for a garage can also contribute to energy efficiency.


When you only need to access the garage for a short period, using the smaller door instead of opening the entire garage door helps conserve energy. This way, you can minimize heat loss or transfer, particularly in climates where temperature regulation is crucial. And as you can imagine, this can also help your lower utility bills.

4. Ventilation and Natural Light:

A man door can serve as an additional source of ventilation and natural light for your garage. When you open the smaller door, fresh air can circulate within your garage. It reduces humidity and odors. Additionally, natural light can filter through the small door, reducing the need for artificial lighting during the day.

5. Increased Fire Safety:

Another lesser-known benefit of installing a garage door with a man door is increased safety. It provides enhanced safety during emergencies where the electric garage door opener is unreliable. With this door, you can quickly evacuate from your property.

Cons of Installing a Man Door

While a man door offers numerous benefits, you also need to consider its potential drawbacks:

1. Limited Size and Accessibility:

One significant limitation of a man door is its smaller size compared to a standard garage door. You cannot carry large items through this door.

So, before you install a garage door with a man door, take this factor into account.

2. Security Concerns:

With a small man door, you also have to think about additional security measures. Thieves and vandals can easily break into your home if the small door is left without an alarm or other security systems. Naturally, you will need to invest in sturdy locks and reinforce the man door to ensure the safety and security of your garage and belongings.

3. Potential for Air Leakage:

A man door may be more prone to air leakage due to its smaller size and potential gaps. If not properly weather-stripped or insulated, air infiltration can affect energy efficiency. It can lead to temperature imbalances and increased energy costs.

4. Additional Installation Costs:

While adding a man door for a garage can offer convenience, it’s important to consider the associated costs. The installation process is often intricate and involves incorporating specialized safety features. This can increase the overall expenses. But yes, going for a local garage door installation expert can help you save some money.
