Fancy burglar alarms are good safety tools, however, one of the easiest ways to keep the bad guys from breaking in is to make your doors burglar proof.
Replace all hollow exterior doors or those with windows with solid ones
Though less expensive, hollow doors only belong in the interior of your house. All exterior doors that allow entry into a home, including side, back, and attached garage doors should be made of Solid wood, Wood core, Fiberglass, or Reinforced metal. Those with windows should also be replaced since the glass can be broken and the intruder can reach through and down to unlock the door.
Sliding glass patio doors
These are easily breached, but these can be easily reinforced with clear poly-carbonate panels that are secured behind the glass on the interior. The same is true of first level windows. Install locks at both the top and bottom. Placing an unbreakable metal or wooden stick or dowel in the sliding door’s track will also block entry by making it impossible to slide the door open with the stick in place.
Exterior doors should have a high-quality deadbolt lock in addition to the doorknob
All exterior doors should have deadbolt locks installed in addition to the doorknobs. Make sure the deadbolt you choose is high-quality Grade 1 or 2 level with a bolt that extends at least an inch into the door “slot” mechanism or a “throw bolt.”
Check door frames
Replace both door frame and door if the door frame is splintering or warped, because any ill-fitting doors can give intruders easy entry. If you do replace both the door and frame, consider using doors are made of fiberglass, with security hinges.
Install a deadlock
A deadlock is like a deadbolt, but it only locks from the inside and there is no keyed entry. This can provide extra security, since an intruder cannot gain entrance unless they can destroy the door frame or lock.
Use heavy-duty strike plates
The metal plate on the door frame that reinforces the hole where the locking bolt enters is called the “strike plate.” These should be heavy-duty and reinforced on exterior doors. The screws that secure the strike plate to the door should attach to the underlying studs in the door, not just the door jamb.
Always lock your doors and windows
All of these safety features are worthless unless you lock up when at home or out. Most intruders simply gain access through an unlocked door or window. Make sure your doors and windows have the reinforcements listed above, and then use them.
