Whatever your angle, at Mangum Builders we are well equipped to bring our hard-won expertise into your corner. From our decades of experience working on Tarrytown houses, we have developed several specialized skill sets, including:

  • Custom construction. Your house, your vision! Some may want to play up the way Tarrytown is nestled into the Texas greenery; others may want to stand out with an iconic, Spanish hacienda build. Our clients vary in what they see when they picture their dream home, but we will use our know-how to bring it to life.
  • Land development. There’s nothing too big or too small when it comes to making sure your property provides you with maximum value. Need the land leveled to provide the perfect tableau for your standout house? We’ve done that. Want to take advantage of what’s already there, down to digging your own wells and septic systems? We’ve done that too. Mangum is here for more than just the house; we want to make sure everything surrounding it is everything you want.
  • Green building. Many Tarrytown residents are committed to conservation, realizing the full value of their property without damaging it’s natural environment. We share that commitment. As an active member of Austin Green Builders, we have made it our business to help clients reduce their environmental impact by building with sustainable and energy-efficient materials, including 80% recycled steel and ICF (insulated concrete forms) walls that are sure to drive down your utility bills.
  • Remodeling and renovations. Tarrytown is known for its beautiful, historic houses, and we take pride in continuing that tradition. Maybe you want to take a unique older property and transform it into something modern, or maybe you want to do a full tear-down to make way for a totally fresh vision. As members of the National Association of the Remodeling Industry, Mangum Builders is a home remodeling contractor with expertise to take something old and make it shine.
  • Ranch construction. Ranch houses are a Tarrywood tradition, and we are just the builder to make sure that a classic still manages to be uniquely you. We are experts at creating ranch properties that reflect the individual styles of our clients, and we want to use that experience to make sure your property is the perfect fit.
