Founded in 1978 and based in Magnolia, Texas, Deanco Construction has grown into one of the Greater Houston area’s trusted leaders in civil site construction. Over the years, we’ve built a reputation for delivering safe, reliable, and high-quality projects, specializing in earthwork and utility services for school districts and commercial clients.

What sets Deanco apart is our approach. From preconstruction planning through completion, we collaborate closely with general contractors, architects, and owners to develop smart, site-specific solutions that balance efficiency, safety, and long-term value.

Every project is managed with the same attention to detail and commitment to excellence, ensuring results that last.

Beyond the work itself, we focus on building trust and strong partnerships. The projects we deliver support our clients’ goals and contribute to the growth of the communities we serve. After more than four decades in the business, our mission remains the same: to provide dependable, high-quality civil construction that makes a lasting impact.
