Window Door Contractors questions, answered by experts

Yes, but adding a deadbolt to some door materials, like steel, may make installation a little bit trickier. For these materials, you will want to hire a locksmith to do the work for you, but be aware that they may charge an additional fee of $25 to $50 or more.

You can use any wood to make an interior door, provided it’s the right thickness. Common options for painted doors include pine or poplar for the stiles, rails, and mullions, and paint-grade plywood for the panels. You can also opt to make your own panels out of pine or poplar if you intend on staining the door instead. Opting for oak, maple, or another hardwood is another great option for a high-end door that will last for decades, but the wood will cost significantly more.

You put shims between the three-sided frame to which the door hinges are attached and the framing of the rough wall opening. Using shims like this will center your door in the wall opening and allows you to make small adjustments to get your door plumb and level for smooth operation. Your shims and the gap they fill will be covered when you install door trim, so don’t worry too much about the appearance.

Longer screws can make a door more secure, but this isn’t a foolproof method for security. Replacing the short screws in your door’s strike plate with screws that are 3 inches long will make it much more difficult for an intruder to force entry by kicking down the door, but it won’t do anything to stop them from picking the lock. 

Outswing doors are more popular for exterior doors as they offer more room for moving items in and out of a home. And because the hinges are on the outside of the door, they’re more secure against potential break-ins. But, outswing doors are more susceptible to the elements and are more expensive. Comparing inswing vs. outswing doors depends on your budget, needs, and overall preference.
