Security Doors questions, answered by experts

Steel doors have a few primary disadvantages. They’re hard to customize since they can’t be cut to fit an opening; they’re cumbersome and thus difficult to install on your own; and they don’t have the same aesthetic appeal as wood doors. Finally, while they’re highly durable and secure, they are susceptible to dents, scratches, and rusting.

There are certainly perks to hiring a general contractor, but we recommend a closet professional. The reason is that their pricing may make more sense for your project. General contractors tend to search out bigger projects, and because of this, will attach a premium to smaller amounts of work. A closet pro may also have access to a wider range of materials than general contractors (and may be able to negotiate better discounts). 

You can determine what size storm door you need by measuring for the storm door. Take the width at the top, middle, and bottom of either your front door or an existing storm door, then measure the height on the left, center, and right of the door. Buy a storm door that matches your measurements' smallest width and shortest height.

French doors that open to exterior spaces are often installed to swing inward, as this makes them more secure than outward-swinging doors, due to the interior hinges being inaccessible from the outside. For interior doors, it’s personal preference which direction to hang your doors, but it’s common to have them open into the larger of the two spaces they’re separating.

A prehung door comes ready to install with the door already mounted in its frame, including hinges and stop molding. Everything is factory-aligned, which makes installation quicker and more precise. It’s a smart option if your current frame is damaged or uneven, or if you’re working with a new build. Instead of hanging a door slab from scratch, you fit the entire unit into the rough opening, shim it , level it, and secure it. Prehung doors are a clean, efficient way to install new doors without having to piece everything together yourself.
