Interior Doors

Interior doors serve many purposes. Sometimes they're needed for privacy, sometimes for separating spaces. We make a variety of styles in a variety of woods and glass - whatever fits the composition of your home.

What Kind of Door?

Your interior doors make a statement in your home. They add a touch of "you" to every room, every closet and every entry way. We have such a huge selection of one, two, four and six panel doors, French doors, shaker doors and glass doors. Our material choices range from mahogany, oak and maple to alder, knotty alder and glass. When considering what kind of interior door to install, think about the purpose of the door. Do you want it to block noise? Do you want it for privacy? Do you want it to be a decorative passage into another part of the house? All of these answers will help you determine what type of material to use and what style would best enhance the look of your home. For example, a heavier wood like mahogany would block noise, while an etched glass door would be a beautiful gateway to another room.

Why Choose Our Doors?

One of our sales representatives will be happy to tell you about all of the doors you're interested in and explain our warranties. Our mahogany and oak wood interior doors, pre-hung solid engineered wood core stile and rail doors have a lifetime guarantee. We know you've got a lot of decisions to make, so we'll offer you our professional advice without any pressure.
