Homes should be places where you feel safe and protected. The threat of home invasions can be unsettling, but fortunately there are steps you can take to reinforce your home and your sense of security.

The first step in making your home feel safe is by installing the proper door security devices. With so many choices on the market, selecting the best home security product can be a daunting task. That’s where the This Old House Reviews Team comes in—in this review, we’ll go over the best door security devices and help you find the right product for your home.

Types of Door Security Devices

When it comes to door security devices, you can think of them as falling into a few major categories with the same end goal: improving the security of your home. Below, you can review the different types of devices and get a sense of which one might be most appropriate for your home security needs.

  • Door jammers—These are simple door reinforcers that use resistance to keep a door tightly shut. They have extendable bars that can be pressure-mounted between the floor and the door knob to prevent forced entry.
  • Reinforcement locks—Typically hardware-mounted, heavy duty locks are installed in addition to the standard locks on your door.
  • Hardware-mounted door security bars—These easy-to-install door barricades placed within sliding door frames prevent an intruder from opening the door.

What to Consider Before Buying a Door Security Device

Before purchasing a door security device, take into account factors like the installation process, dimensions of your door, placement of the device, and the device material itself.

Installation process

Consider whether you want a door security device that’s permanently installed, like a master lock or hard-ware mounted bar, or something that can be taken down and stored when not in use, like a pressure-mounted door jammer.

Removable devices are portable and typically require little or no installation, but you often trade extra security for these conveniences. In comparison, a permanently installed device may require more upfront labor and cost, but they are often sturdier and more reliable than the removable devices.

The dimensions of your door

While doors often have universal design elements, their exact dimensions can vary. You will need to factor in whether a product will be compatible with the height, width, and thickness of your door. Before buying a door device, measure your door’s dimensions and read product descriptions carefully. If you really want a flexible option, go with an adjustable device to make sure it will fit to your door’s specifications.

Placement of the device

Some security devices are designed for sliding doors only, while others can be used on hinged doors and sliding patio doors. Read the product description carefully to determine whether the device is compatible with your home’s floor type. Some pressure-mounted door jammers will not be compatible with carpet or linoleum, for example, but will work great on wood or tile.

Door security device material

Yet another important factor to consider when selecting a door security device is the material. Look for a durable material like steel or metal over plastic, which may not be reliable under high pressure. If you want to protect your home’s floors from any force placed on it by the security device, look for options with rubber footing.

Frequently Asked Questions about Door Security

How do I make my door more secure?

You can make your door more secure by installing a strong security device. You can choose between multiple types of security devices, ranging from simple door jammers to permanently installed deadbolt locks.

How do I install a security door?

To install a security door over your door, begin by measuring your door. Choose a security door that matches the door you want to protect. Position the door hinge side in front of your door, leaving a 1/8-inch gap between the lock-side of the door and the inside edge of the door.

Mark the location of the mounting and pre-drill holes where marked. After the holes are drilled, fasten the security door to your door with one-way screws.

Installation for security doors may vary depending on your model. Be sure to read the installation instructions for your specific security door before you begin the installation process.

Are door jammers effective?

Door jammers are some of the most effective types of security devices, and they’re a great option for anyone looking for a simple way to enhance their door’s safety. They’re also especially useful for renters and travelers who don’t have permission to permanently alter the lock on their door.

What is the best type of door security device?

The best type of security device for your door will depend on your home security needs as a homeowner. If you’re looking for a portable, simple option, you may want to consider a door jammer. If you’re looking for a higher level of security, a deadbolt or barricade lock may be a better fit.

How can I protect sliding glass doors?

Protecting your sliding glass doors from a break-in begins with choosing the right doors. Make sure that your doors are made from reinforced glass or plastic—not thin, easy-to-break glass. Place a wooden or metal dowel in the track of the door to prevent quick forced entry. You may also want to consider adding a glass break motion sensor to your home’s security system if you have one.
