I have some experience as a DIY'er installing pre-hung Masonite Interior doors in my home. I'm about to pursue an installation of exterior-type doors for my basement and a first floor bedroom. In addition to an alarm, I want these doors to be stronger and more secure to segment the basement and bedroom from the rest of the house to prevent break-ins. This is why I intend on a metal or solid wood exterior style with heavy-duty locks.
My question then is - Is there a different way of installing a heavier and/or more secure door than nailing pre-hung doors to the framing? Should I use screws instead, or install these somehow differently? Also, what would be the best lockset for security?
On a separate note...After seeing how doors are installed and framed, I'm beginning to believe that doors are not so secure anyway, even with a deadbolt. I could easily see two heavy men charging a door and smashing the deadbolt through the framing. What do you think?
