Our Mission
To deliver construction excellence through unwavering quality, transparent communication, and client-first values — building structures that stand the test of time and relationships that last a lifetime.
Ironclad Construction Co. was founded on a simple belief: every client deserves a contractor who treats their project with the same care and precision as their own home. Twenty years later, that belief drives every nail we drive and every wall we raise.
Ironclad Construction Co. was born in a two-car garage in Austin, Texas in 2003. Founder James Harrington, a third-generation builder, had a singular mission: to create a construction firm that combined old-school craftsmanship with modern project management rigor.
Starting with residential renovations, we earned a reputation for quality and transparency that spread by word of mouth. By 2008, we had expanded to commercial projects. By 2015, we were operating across the entire Southwest with a team of 200+ skilled professionals.
Today, with over 500 completed projects and $2.4 billion in delivered construction value, Ironclad remains an independent, family-guided company — driven by the same values that started it all.
To deliver construction excellence through unwavering quality, transparent communication, and client-first values — building structures that stand the test of time and relationships that last a lifetime.
To be the most trusted construction company in America — recognized not just for the buildings we create, but for the positive impact we have on every community we build in.
We say what we do and do what we say. No exceptions, no surprises, no excuses.
Good enough is never enough. We hold ourselves to the highest standard on every project.
Every worker goes home safe every day. Safety is non-negotiable on every Ironclad job site.
Our clients' goals are our goals. We listen, we adapt, we deliver exactly what was promised.
