Reinforce a Door in 5 Ways

The safety of your home and loved ones is a top priority, and one of the first lines of defense against intruders is your doors. A secure door deters potential burglars and provides you and your family peace of mind. In this comprehensive guide, we'll show you how to reinforce a door effectively to bolster your home security.

Common Weaknesses of Home Doors

Common weaknesses in home doors can pose significant security and safety risks for homeowners. To address these vulnerabilities effectively, it's crucial to understand the potential issues that doors may face. The following are weaknesses:

  • Doors made from low-quality materials.
  • Incorrect door installation.
  • Weak or short deadbolts.
  • Weak or deteriorating door frameworks.
  • Windows near the door.
  • Lack of additional security features such as a security bar, door chain, or smart locks.

Reinforcing the Door Itself

Before reinforcing your door, it's imperative to thoroughly assess the door itself. The material from which your door is constructed plays a pivotal role in determining the level of security and protection your home can attain.

Suppose you find that your door is a robust, solid-core door in excellent condition, devoid of any signs of rot or rust. In that case, you can bolster your door's security by enhancing its hardware and incorporating additional security features.

However, if you're dealing with a builder-grade hollow core door, a lightweight decorative door, or if the areas where the locks, handles, and hinges attach are soft or showing signs of rust, it's high time to contemplate investing in a new door. Regardless of how robust your lock might be, an existing door in such a compromised state can be easily breached, particularly through forceful kicks.

The most resilient doors on the market are typically crafted from solid wood or steel. Nevertheless, some highly durable fiberglass doors are available, some of which boast wood cores, offering strength and aesthetic appeal. Opting for one of these doors will pose a formidable challenge to any would-be intruder attempting to kick it in, and they will readily accommodate upgraded locks and hardware.

Reinforce a Door Frame (Door Jamb)

To bolster door security, homeowners can reinforce the door frame, particularly the door jamb. The door jamb, distinct from a door jammer, supports the door's weight and aids in smooth operation. It plays a vital role in preventing forced entry.

Reinforcing the door jamb involves adding extra connecting material, like a robust metal or wood strip, securely fastened deep into the door frame. This strengthens the connection, making separating the door from the jamb harder.

Additionally, reinforcing the door frame with a layer of steel over the door jamb, where the strike plate resides, prevents frame splitting and ensures the door remains securely locked, even under forceful entry attempts.

Reinforce Exterior Doors

According to the ADT statistics, 34% of burglars enter through a front door, and 22% of burglars walk into a house through a back door. Thus, securing exterior doors is essential for the safety and protection of your home. Here are four smart devices to consider when reinforcing exterior doors.

Keyless entry systems

Consider implementing keyless entry systems using keypads, fingerprint recognition, or facial recognition. These advanced access control methods enhance security by eliminating the need for physical keys, which can be lost or stolen.

Security cameras

Install outdoor security cameras near your exterior doors to monitor and record any suspicious activity. Some cameras have motion detection capabilities. When motion is detected near your exterior doors, the camera can trigger recording and send alerts to your smartphone or security system. They can also provide visual evidence in case of a security breach.

Video doorbells

Video doorbells allow you to remotely see and communicate with visitors at your front doors via a smartphone app. They often include motion detection and can capture video footage when someone approaches your door, enhancing overall security.

Door sensors

Integrate door sensors into your security system. These sensors can alert you to any unauthorized entry attempts and trigger alarms, notifying you and potentially deterring intruders.

Note: If your exterior doors are equipped with decorative or functional glass panels, you may opt for reinforced or laminated glass. You also may choose grilles or bars over glass panels in your exterior doors.

Reinforce the Door Lock

The strength of a door hinges significantly on the quality of its locking mechanism. While your home's door may be constructed from incredibly robust materials, the efficacy of the locks securing it is paramount. Without proper locks, a door can become susceptible to forced entry.

Enhancing your door's lock security can be achieved through several effective methods. For instance, if your door features European cylinder locks, you can replace or upgrade them with locks boasting lock-proof cylinders. Additionally, homeowners can consider augmenting the lock's security by adding security pins or even modifying the lock spring material.

If your door lacks a strong deadbolt, selecting a high-quality lock with an ANSI rating of either 2 or 1 is imperative. ANSI ratings measure a lock's resistance to external forces before it gives way. A lock with an ANSI rating of 2 can endure five impacts of 75 pounds each, making it a formidable deterrent against

Reinforce Interior Doors

While exterior doors typically come equipped with reasonable security features, the same cannot always be said for interior doors. When reinforcing the security of interior doors, the most effective measures often revolve around enhancing the striker plate and door hinge.

For the striker plate, replacing the short screws with longer ones (typically 3 inches or more) can firmly anchor it into the door frame, making it more resistant to forced entry.

For the door hinge, similar measures can be applied. By using longer screws in the hinge, you increase its strength and deter easy removal. Hinge pins can add an extra layer of security by preventing door removal through hinge pin removal.

How to Maintain Your Doors?

Proper door maintenance is essential to ensure your home security. Here's a comprehensive guide on how to effectively maintain your doors.

Inspect for damage: Inspect your doors for signs of wear, damage, or rot. Check for cracks, peeling paint, or water damage. Repair or replace damaged components promptly.

Check for loose hardware: Inspect the door hardware, including screws, knobs, handles, and hinges. Tighten loose screws or bolts to ensure the door remains secure and functions correctly.

Adjusting door alignment: If your door doesn't close properly or is sticking, you may need to adjust its alignment. This can often be done by tightening or loosening hinge screws or adjusting the strike plate.

Security check: Check the locks, deadbolts, and strike plates for proper function and security. Replace or upgrade locks if necessary to enhance your home's security.

Consult a professional: If you're unsure how to address specific door issues or notice significant damage, consider consulting a professional door repair or replacement service.


1. What is the best door to avoid burglary?

The best type of door to help avoid burglary is a solid core or solid wood door, preferably one that is reinforced with metal or has a metal core. These doors are more difficult to break through compared to hollow-core doors or doors made of weaker materials.

Also, consider consulting a security professional or locksmith to assess your home's security needs.

2. How do you secure a door from the inside without a lock?

You can employ various methods to secure a door from the inside without a lock. Start by using a doorstop or wedge underneath the door, preventing it from being pushed open. Alternatively, employ a door barricade device, a security bar, or a surface-mounted bolt to fortify the door's resistance. In a pinch, use a sturdy cord or rope looped through the handle and tied to heavy furniture.

For sliding or double doors, insert a dowel rod or a DIY security bar. You can even loop a belt around the doorknob or place a heavy piece of furniture in front of the door. Portable door locks that clamp onto the door and frame offer another option. While these methods enhance security, consider consulting a professional for a long-term, robust solution.

3. Why is it important to reinforce home doors?

Strong doors bolster security by deterring potential break-ins and providing peace of mind while offering safety benefits during emergencies. They safeguard your privacy, enhance energy efficiency, reduce utility costs, and can withstand harsh weather conditions, protecting your home's interior.


Reinforcing a door is a practical and essential step in enhancing the security and safety of your home. By following the steps outlined in this guide, you can significantly improve your door's resistance to forced entry and make it more durable against wear and tear.
