Security Doors questions, answered by experts

You should rekey your house every three years to minimize the chances of someone gaining access to your home. You can do it more than that, but it depends on the level of foot traffic and visitors you get. Businesses, for instance, routinely rekey their locks every six months to a year. If you experience a break-in or a house key has gone missing, rekey the locks immediately. The same goes if your lock becomes damaged.

Steel doors are among the most affordable options for your front door. Steel doors are worth the cost if you’re looking for a budget-friendly door that maximizes home security and energy efficiency. Plus, they can last up to 100 years, making them a high-quality and long-term investment.

The best material for door sills depends on durability, aesthetics, and budget. Standard options include wood, metal, and stone. Wood offers a classic look but may require more maintenance. Metal sills, like aluminum or stainless steel, boast durability and resistance to corrosion, making them suitable for modern designs. Stone sills, such as granite or marble, provide elegance and longevity but are more expensive. Ultimately, the choice depends on personal preference and practical considerations.

Steel doors last the longest, sometimes upwards of 100 years. Fiberglass comes in second, with a lifespan of 70 years. Wood doors have the lowest lifespan, with some wood types only last 20 to 40 years.

A door frame is not the same as a door casing. A door frame is the framework surrounding the entire door that supports the area from which the door hangs. The frame is made up of multiple parts, including the door jamb, head, and sill.

Casing refers to the trim work located around the door frame. It connects the door frame to the wall with decorative trim.
