Who We Are

About Severn Excavation

Severn Excavation is owned and operated by Tommy Malone, a Marine Corps veteran with an engineering degree and over a decade of experience in the trades. Before the business got started, Tommy worked in pool construction, new home builds, and structural hardscaping. That background combined with training in quality control and site engineering is what sets our work apart today.

We don’t cut corners, and we don’t overbook. We keep our team intentionally small so we can stay focused on doing clean, efficient, quality work, whether we’re trenching for a sewer line, installing a drainage system, or building a retaining wall that needs to hold up for decades.

Tommy is directly involved on every job, overseeing the details on site, making sure the work gets done safely, precisely, and to spec. If you're looking for a crew that shows up, works smart, and leaves things better than we found them, that's what we’re here for.
