Local competition in Marthasville

Marthasville shares ZIP code 63357 with the surrounding area, where 108 employer businesses were counted in 2023. Among them:

  • Remodeling contractors: 10. Their website should show a gallery of past remodels, a clear list of what you do and don’t take on, and a form that sends estimate requests to your inbox.
  • Full-service restaurants: 4. Their website should show the menu, hours, location and photos of the food, easy to read on a phone.

Across Warren County, County Business Patterns counted 654 employer establishments in 2023, and the Nonemployer Statistics add 2,695 businesses with no payroll, most of them self-employed owners. Compared with the U.S. as a whole, Warren County leans toward homebuilders and building contractors (50 establishments, 2.5 times the national share). In that business, buyers compare builders for months before they sign, and the website should show finished homes by project, the steps of building with you and the areas you build in. Specialty trade contractors are also overrepresented (85, twice the national share). Marthasville’s working residents are concentrated in education, health care and social assistance (25.8%) and manufacturing (14.7%).

A city that keeps changing

Five years of estimates add up to 37 more residents (2.9%). Statewide, the change was +1.9%. New residents mean new customers who don’t have a favorite plumber, dentist or restaurant yet.
