We are committed to providing you with the highest quality & most affordable fiberglass entry doors on the market. We aren’t offering doors that won’t last in the Florida climate or serve no benefit to you. That is why we only offer fiberglass doors with composite.

Our Builders Hardware Inc or BHI Doors, as well as Masonite doors by Florida Made Doors are the best front door replacement options on the market. While both companies offer wooden front doors, exterior steel doors, and exterior wood doors, the only kind of door we recommend is fiberglass doors with composite. Exterior fiberglass doors are the best replacement doors for all areas but especially the coastal areas of Florida. We have many pre-hung exterior door options including decorative glass front doors, modern minimalist front doors, and even several panel options for front doors. The door configuration we see most often is the front (entry) door with sidelights. Usually, the sidelights are alongside double entry front doors. Exterior French doors, double doors, and glass doors are just a few options when it comes to exterior front doors.
