Security Doors questions, answered by experts

The strike plate, hinges, and handle are the parts of a door most prone to damage. These parts see the most frequent use, causing them to wear and twear faster than other parts of a door. If you’re experiencing door issues, check these three parts first to see if they need repairing or replacing. 

To build a standard size, six-panel door yourself, you’ll need four 2-foot by 6-foot boards, one 2-foot by 8-foot or 2-foot by 10-foot board, and a sheet of 3/4-inch, paint-grade plywood. The 2-foot by 6-foot boards will serve as your stiles, top rail, and horizontal and vertical mullions, and the wider board will serve as the bottom rail, which is usually wider than the other horizontal pieces. The plywood will serve as the panels, but you’ll need around five 1-foot by 6-foot boards to make your own panels if you want to stain the door rather than paint it.

As long as you do it carefully, you can sand and restain hollow core doors. However, it’s risky because the veneers on hollow core doors are so thin that sanding and restaining might cause damage to the doors. If you do move forward with this project, sand the doors lightly with a medium-grit sandpaper.

Adding a doggie door can allow a burglar access to knobs and locks on your door. If your pet door doesn’t come with an alarm, you can add a weight sensor alarm that will trip if anything heavier than your pet enters through it. Adding a motion sensor light to the room your pet door is in can also help deter burglars.

A door sill is the bottom portion of your door frame, while a threshold is the transition piece that separates the two types of flooring between rooms, or serves as the transition between the interior and exterior on an exterior door. The threshold sits on top of the door sill. A kick plate is a protective plate that sits against the face of a door to prevent damage to the door from feet and shoes. You’ll usually only find kick plates on exterior doors, while every door has a door sill, and most exterior and interior doors have a threshold.
