Can't go wrong with two!

we have double doors front and back, both fixed doors have bolts top and bottom.

Two!

Well...if it's security that is your primary concern:

--Don't have any double doors;

--Don't have any glass doors'

--Use only steel doors with cremone bolts;

--Have no less than 4 Rottweilers

You're welcome.

Any double door can be easily kicked in. You want 2 to prevent warping.

Go with a multi-point locking system. New doors should always be multi-point in the 21st century.

I agree with Virgil that security is not going to improve with an extra bolt, if getting into the house is the aim a window is a much easier access.

Any double door can be easily kicked in. You want 2 to prevent warping.

Exactly, plus, when you open/close the door, the top would rattle and eventually cause problems without it being secured.

Are you sure the proposed new door is exterior grade? Single top pin is appropriate for interior.

Exterior grade door.

Exterior grade jamb.

Weather stripping all sides including door bottom and threshold.

Two.

Definitely 2 if you can still do it, and a multi-strike latch if able to

But if it makes you feel better, 99% of thieves won't try to force open your front door - they'll look for unlocked doors or pry open a side/back service door. Noone would stand out front banging on door trying to break in and bring that much attention to themselves

Thanks for everyone's input. It is a good quality exterior door. Turns out our Home Depot associate was wrong and has since apologized, there are two flush bolts in the stationary door, one top and bottom. We are now looking into also getting a multi-point locking system based on all the suggestions.

Thanks!

Do you have options of anywhere other than HD to buy your door?

Thieves in our area are entering homes by forcing open french doors or sliders on second story master bedrooms ... it seems many homeowners skimp on their security systems and don't add sensors to second story doors/windows or don't add any motion sensors upstairs.

Another reason for two bolts is to make sure the doors can't move/rattle during high winds and set off the alarm door sensors.

So the HD associate didn't know all the features of a product that they sell; when I think of all the product they sell and all the details of each product, it doesn't surprise me. What gets me is when I walk out of a hardware store and realize the kid that helped me find what I wanted probably knows more about building products than I ever will.

If you want security, get a Belgium Shepherd and don't feed him before you go out in the evening. Nobody in their right mind will step inside your home, if not . . . doggy snack.

All exterior doors two and interior doors one.

Mark, unless your dog is trained in Personal Protection, most snarling barking dogs, even Belgian Shepherds, will back down very quickly once a stranger enters the house when the dog(s) are home alone. There is a trainer in Florida that has several youtube videos that do a good job of showing this. He puts on a padded bite suit and "breaks" into customers homes. Customers who have told him their dogs would rip him apart! 99% of the dogs were quick to back down and want nothing to do with the intruder.

My big and vicious sounding/looking dog stays in a crate when we are gone. I rely on my security system with sensors and motion detectors. The last thing I want is someone to hurt or kill my dog ... I would rather they just steal "stuff".

Now, if you are home and someone breaks in, there might be a chance that your dog might try to help you out, but I wouldn't rely on that as my only home defense plan.

The dog was vicious to anyone who came to the front door or any stranger . . . while we were home. I didn't think it would be different when we weren't home. Of course we trained him not to lay on any of the furniture and he was very good at it, but there was this mysterious warm spot on the couch after we came back from being away for any length of time.

Dogs are a DETERRENT. Making your house less attractive than the house next door without a dog.

It really matters not if they will bite - no one should get that far.

(and also agree that in this day and age - multipoint locking mechanisms should be the norm.)

I've got two barky dogs, a miniature dachsund and a black lab pit bull mix. They only prevent the attempt and they're really good at getting under the covers and snuggling in for a nap. If someone actually got in the door, they'd be licked to death.

Some dogs have tails that are the weapon.

I've heard that loud dogs are more of a deterrent than fierce ones.

A loud German Shepard and a loud Pekinese are not the same thing...

This actually happened in our Alamogordo house. Religious litter dropper came to the door and stuffed literature in the door jamb. Comanche, our blue male Texas Lacy Game Dog bayed the door. Religious litter dropper ran from the porch as fast as she could hobbling with her cane.

We had a standard dachshund who woke up one night and just started barking, snarling. facing the front door. He would't stop and I was home alone so I called 911. The dispatcher couldn't believe what she was hearing and sent a unit out. Fred barked and growled until the police got there. Whoever had been prowling around was long gone.

My current dog is an attack dachshund and really fierce, when his food is put out, that is. Nobody messes with his food.
