Front Entry

Do you need a new front door? As a focal point of your home’s façade and one of the first things people see when they visit your home, the front entry door should be attractive and help your home make a good first impression. More importantly, it should be secure and durable.

The Shanco team offers a variety of high-quality doors to complement any home. We most often recommend ProVia doors and custom wood doors.


A good patio door should be not only attractive but also durable, secure, and energy-efficient. If your door isn’t up to par, it’s time to install a new one. There are two main types of patio doors: hinged and sliding. Hinged, or swinging, patio doors open like a front door—they are hinged on the side. Sliding patio doors glide open along a track and take up no extra space.

The Shanco team offers a variety of high-quality doors to complement any home. We most often recommend ProVia doors and Simonton French and sliding glass doors.
