Swallow & Sons Excavation

Swallow & Sons Excavation is a family-owned business delivering honest, high-quality excavation and site work across Northern New Hampshire. Based in Lancaster, we specialize in full lot development, septic system installation, trenching, grading, and land clearing—done right the first time, with no cut corners. This is a hands-on operation where the owners are on-site and the phones get answered. From prepping a house lot to managing the full build through trusted subs, we handle the heavy lifting so you don’t have to juggle multiple contractors. Local. Reliable. From dirt to done.
