Who we are
More than a flooring company, a family called to serve.
Cornerstone Epoxy exists to honor God by serving families and businesses with honesty, integrity, exceptional craftsmanship, and genuine care. Our goal isn't a completed project, it's a relationship that continues long after the last coat is dry.
Why Cornerstone
Four commitments that shape every project.
Christ First
Our faith shapes how we lead, serve, and treat every family and business we're invited into.
Family Always
We treat your home the way we'd treat our own, because family is our first calling.
Integrity Without Compromise
Honest pricing. Honest timelines. Honest work, even when no one is watching.
Excellence in Every Detail
Proper prep, premium materials, and craftsmanship you'll be proud of for years.
Our flooring systems
Built for every space.
From a single-car garage to a full commercial facility, the same standard of prep, materials, and craftsmanship.
Residential
Garages, patios, and living spaces built to handle daily life, and look beautiful doing it.
Commercial
Showrooms, shops, and storefronts with durable, professional finishes that make an impression.
Industrial
Warehouses, service bays, and heavy-use spaces coated with 100% industrial-grade epoxy systems.
Why customers trust us
Built correctly the first time.
These aren't sales points, they're the reasons your floor will still look and perform beautifully years from now.
100% industrial-grade epoxy
Full-solids systems built to take heat, chemicals, and years of daily use, not thin DIY coatings.
Professional concrete prep
Mechanical grinding and moisture testing on every job. It's the step that makes a floor last.
Premium polyaspartic topcoats
UV-stable, high-clarity topcoats that stay beautiful, and protect the epoxy underneath.
People-first service
Clear communication, clean job sites, and a team that treats your home like their own.
