Owner Operated · Built for Missouri
One Nation. One Purpose.
Irrigation systems, roofing, decks, concrete, and the practical repairs that keep a property working.
One Nation is the working name of Steven Sansoucie.
A broad scope.
One accountable owner.
One Nation is Steven Sansoucie — an owner/operator serving Missouri and surrounding areas.
The scope moves from sprinkler heads to shingles, but the standard stays simple: understand the work, make a plan, and see the job through.
What the work can include
From the ground line
to the roof line.
- 01
Irrigation & Sprinklers
New installations, repairs & maintenance, inspections, and system upgrades for lawns and landscapes.
- 02
Roofing
Asphalt shingle roofs plus flat-roof work — EPDM and TPO membrane, insulation, and parapet repair.
- 03
Decks & Exteriors
Deck restoration, staining, and exterior carpentry that brings outdoor spaces back to life.
- 04
Concrete & Flatwork
Walkways, curbs, and slab work — formed, poured, and finished clean.
- 05
Sheds & Outbuildings
Framing, sheathing, and siding for sheds and accessory buildings, from skids to roof.
- 06
Interior Repairs & Floors
Hardwood floor refinishing, commercial floor prep, and the repair list nobody else gets to.
The whole property.
Working better.
A stronger outdoor space is more than one isolated repair. Water, structure, access, and finish all have to work together.
What lives
under the lawn.
A typical irrigation system divides the property into controlled zones so turf, planting beds, and high-use areas can receive water where it is needed.
