Door Reinforcement For Extra Security

Home Door Reinforcement Safeguards Against Kick In Burglary.

You fully realize the importance of ensuring that the external doors to your home are not an easy point of entry for burglars or for home invaders.

You have made sure that all doors into your home are of good, solid exterior construction and you have deadbolt locks fitted with a throw of at least one inch. 

Also, every time that you, or a member of your family leaves the house, those doors are closed and those deadbolts are locked without fail.

Good for you. 

Is there more that you can do?

Yes there is.  A good lock correctly fitted will reduce the risk of picking, bumping or the lock being wrenched off the door.

A solid exterior quality door will reduce the danger of burglars kicking in or shoulder barging their way through your door.

However you can further improve the chances of your entrance withstanding a kick in attempt by taking a few simple door reinforcement measures.

It is a sad fact that many home exterior doors are attached to a weak and thin jamb by screws that are of insufficient length.

Likewise the strike plate, or strike cup, is often set into a thin jamb and held by short screws, sometimes by screws just one inch long. 

If brute force is applied, and with short screws fitted it would not take much, although the door itself may resist it, the screws do not and the deadbolt is busted free.

Remove one of the screws holding on the strike plate and check how long it is.

If it is not around three and a half inches then it is likely only holding the strike plate to the thin jamb. You want the screw to go through to the framing. Check all the screws and replace with long ones.

You have reinforced your door for the cost of a few screws.

Do you want to further fortify your external door?

Door Jamb Reinforcement.

Consider fitting a doorjamb shield. These are available from several manufactures and consist of a steel strip 40 to 60 inches long. 

There are holes in the shield to match with your deadbolt strike plate and latch bolt strike plate (if you have one.)

Naturally the screws that fix the jamb shield are of the longer type.

Now you have more screws holding that strike plate and longer ones at that.

You also have steel instead of soft wood around the important area of your doorjamb. You have improved door reinforcement; your door will withstand greater brute force.

As a bonus, the jamb shield will narrow the gap between the jamb and the edge of the door. This makes it more difficult for burglars to jimmy the door open.

Protecting The Lock.

Now check the screws that hold your deadbolt lockset that is mortised into the door edge. Short and stubby? Replace those.

As you will be screwing into the door edge care will need to be taken, you may not want to use three and a half inch screws but the longer the better, use at least two inch. Carefully drill pilot holes so that your screws go in straight and square.

Door edge shields are available that give additional protection to the lock area.

However if you have a jamb shield fitted there may not be a sufficient gap, between the door and the jamb, to allow you to fit both.

Door Reinforcement – The Hinges.

Now that you have the lock side of your door sufficiently reinforced you need to protect the hinge side. That’s right, many homeowners simply do not consider that hinge screws can be ripped right out by a hefty kick or barge to the door.

If your lock is good and everything is reinforced on that side, then the door hinges become the most vulnerable point.
