Security Doors questions, answered by experts

The lifespan of your door depends on the door type, its wear and tear, and the weather conditions in your area. For instance, front doors last between 20 and 60 years, depending on the material. Garage doors, on the other hand, last between 15 and 30 years. Interior doors don’t get hit with the elements and can last between 20 and 50 years, if not more. 

A door swells up when there’s a lot of moisture in the air. Wood doors are porous, and the elements can cause them to expand with humidity and contract with dry air. Prevent swelling by coating the door in weather-resistant paint, which creates a barrier to seal out moisture. Otherwise, go with a water-repellent finish after the fact. On the plus side, this problem will go away once the weather changes.

When hanging a door frame, it’s recommended that you use screws, not nails. Screws are more secure, easier to tighten, and easier to remove if you need to adjust the frame. On average, the cost to replace a door frame is about $400, but you can save on labor costs if you’re confident in your ability to DIY the project. 

For most doors, you can use a 1-inch chisel to create the mortise for the strike plate. In addition, you can use a 3/4-inch chisel for more refined cuts and to clean up the edges of your mortise. The smaller tool is handy when squaring off the edges around the hole for your latch.

While spring and summer’s temperate weather can make the project more pleasant and give you more daytime hours to start and complete it, there’s otherwise no advantage to framing a door in spring or summer versus fall and winter.
