Custom Home Builder in Geismar, Louisiana
Owner-led custom homes, major remodels, and additions — built to an uncompromising standard for Geismar families who expect the very best.
Your Geismar Custom Home Builder
Geismar is one of Ascension Parish's fastest-growing communities — offering new subdivisions, larger lots, and easy access to both Baton Rouge and the Gonzales corridor. Families are choosing Geismar for the room to build and the value that Ascension Parish land provides relative to East Baton Rouge.
Nelson Custom Builders brings the same owner-led, uncompromising standard to Geismar that we bring to every community we serve. David Nelson personally guides every project from the first conversation through the final walk-through — custom homes, major remodels, or additions, all tracked through a private Buildertrend project portal so you always know where things stand.
