"Hassan was hired to replace my trash compactor and redo my countertops. He did a great job with both. He removed the trash compactor the same day he came to give me the quote. He went above an beyond as I had kept adding little projects along the way ... replace my doorbell, fix a bedroom closet door, remove a latch on my basement door. He is such a good worker. Communication was a problem in the beginning with him not keeping in touch with me as to his work schedule, but that was worked out. As I will be moving in the near future, I told him I will be calling on him again if I need his help at my new home."

Doors questions, answered by experts

Spacing a door is tricky since you need to leave enough of a gap for the door to move freely and not get stuck when the slab and frame contract and expand in dry and humid conditions. The ideal gap between a doorframe and slab is 1/8 of an inch. If the gap is any larger, the door will feel drafty. But if the gap is any smaller, the slab can get stuck due to weather changes.

You have several options when choosing the best lumber for your door jamb. Pine is the most common material due to its resistance to swelling. Fir is strong and durable. You could also go with birch or alder. Any wood with a tight grain will work for this project.

Screen doors (sometimes called barrier doors) and security doors serve different primary functions. A screen door's main purpose is to allow airflow and keep pests out, featuring a lightweight frame and a mesh screen. A security door, however, is a heavy-duty structure designed to prevent unauthorized entry. Security doors are installed with permanent screws into the home's walls and are often equipped with deadbolts or other heavy-duty locking mechanisms for enhanced protection against intruders.

A slab door is a standalone door without a frame or hardware. A prehung door is a complete set that includes the door, frame, hinges, and sometimes the doorknob and lockset.

In most cases, a prehung door is the better and easier option to install, especially for DIY projects or exterior applications, as they often come pre-weatherproofed. They require fewer tools and less experience to install properly. Although prehung doors are heavier and have a higher upfront cost, the investment is often worthwhile for a complete upgrade that includes a new frame.

A slab door may be a better choice if you are on a tight budget, have a custom-sized wall opening, or only need to replace the door while keeping the existing frame. While the initial cost is lower, you will need to purchase all the hardware separately and do more DIY work to hang it, which may not result in significant time or money savings.

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.
