Built on tradition. Crafted for today.

Meet Jacob Misiel Barrios Sandoval
Owner & Master Carpenter
Jacob grew up surrounded by craftsmen. The smell of fresh-cut cedar, the rhythm of a well-set hammer, the patience of a master measuring twice — these were everyday lessons. He carries that inheritance from Mexico into every project he builds in Minnesota.
After more than a decade learning the trade across residential construction, deck building, and fine carpentry, Jacob founded JSA Construction with a simple promise: treat every home like it belongs to family, and build it to last generations.
Today, JSA Construction is fully licensed, insured, and trusted by homeowners across the Twin Cities and greater Minnesota — known for honest estimates, meticulous work, and showing up when we say we will.
What we stand for
Craftsmanship First
Every joint, every cut. We build like family will be sitting on it tomorrow — because often they are.
Heritage & Pride
Traditional Mexican carpentry meets modern Minnesota design. Our work carries that pride into every board.
Community First
Honest pricing, clear communication, bilingual service. Neighbors deserve to be treated like neighbors.
