Security Doors questions, answered by experts

If a sofa doesn’t fit through the door, try angling it to maneuver it through. You’d be surprised at how often this works. Next, remove the legs and cushions and try again. If that doesn’t work, consider an alternate entry point like a window or a back door. When all else fails, contact a pro. 

If your home cannot accommodate a traditional garage door, there are plenty of other options to choose from. Consider installing a door made of glass, fiberglass, sheet metal, or faux wood. You can also choose a unique style like a folding, tilt-up, sliding, or carriage door. Consult a local garage door installer to discuss the options available for your garage shape and size.

Begin by determining which way you want the door to swing based on the layout of your room. Traditionally, left-handed doors have a doorknob closest to your left hand, and right-handed doors include a doorknob closest to your right. Right-handed doors with left hinges swing inward and vice versa. This can vary based on the layout of your home, though.

Yes, prehung doors include a door jamb. Prehung doors are sold as a single piece with the door frame already constructed, including the hinges. The only part missing is the trim, which you add after fastening the door. They are more expensive than slab doors but are quicker and easier to install. Prehung doors come in an array of sizes, so there’s likely an option to fit any doorway you need.

The most common size for an interior door is 80 inches tall and 28 to 32 inches wide. However, a standard interior door can measure anywhere from 24 to 36 inches wide, depending on its intended use and the available space. According to most building codes in the U.S., a door must be at least 80 inches tall and 24 inches wide.
