Window Door Contractors questions, answered by experts

A front door lasts between 20 and 100 years, or an average of 30 years. How long it lasts depends on the type of material, the environment, and how well you maintain it. A door with coverage over it will last longer than one exposed to the elements. Using high-quality paint or sealants can also help extend the life of your front door. Wood front doors tend to have shorter lifespans than other materials.

A slab door is a standalone door that's not attached to a frame. A prehung door includes a slab door, a door frame, and the hardware necessary for installing it, like hinges. 

Replacing entryway doors can increase your home’s value and have a return on investment (ROI) of up to 65%. This includes sliding glass doors, which let in more natural light and complement a space's style. Sliding glass doors increase your home's curb appeal and can simplify the transition to your outdoor space.

The best patio door material comes down to what matters most. Wood doors win for custom looks and natural warmth, but need regular maintenance. Steel options offer better security and low maintenance; however, the design choices are slim. Vinyl is an easy pick—affordable, low-maintenance, and energy-efficient—even if it’s not the most high-end looking. Ultimately, the right material for your patio door depends on whether you’re chasing style, security, simplicity, or a little bit of everything.

Plenty of building codes dictate what you must install in your home, but door sweeps are optional. However, they're a low-cost addition with many advantages. So, installing a sweep on all your exterior doors is in your best interest. You'll save money in the long run and stay more comfortable year-round.
