Window Door Contractors questions, answered by experts

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). 

Interior door thresholds are usually attached using finish nails, and some contractors will also use construction adhesive under the threshold to hold it in place. Exterior door thresholds are more commonly screwed to prevent them from pulling up when people step on the raised edge on the outside of the door. Exterior doors also include caulk sealant on the inside to prevent water and air from seeping through.

No, exterior doors don’t need to be prehung, although choosing a door that is prehung makes the installation process far easier. Installing an exterior door that isn’t prehung requires carefully maneuvering the heavy door into place in your door frame, making sure it’s level and plumb on all sides, and then attaching the hinges so that they’re perfectly level and are affixed to the right part of your frame and door. Prehung exterior doors are far more DIY-friendly.

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.

The width of your door jamb should match your wall thickness exactly, so it depends on your wall. For standard door openings, the width is equal to the width of a 2-by-4-inch  stud, plus the width of the drywall on both sides—about 1/2 inch each—which comes out to 4 9/16 inches. Block walls and framed walls that use 2-by-6-inch framing require a door jamb that’s 6 9/16 inches. You should always measure your finished wall thickness to get an accurate width for your door jamb material.
