We are a locally owned cape cod business, owned and operated by native cape codder Sam Dunford. We have been in business since 2012 providing quality work at a competitive price. From septic systems and excavation, to landscape construction and hardscapes, S.H. Dunford is your one stop shop. Follow us on Facebook! Facebook.com/shdunford
"Sam was prompt, professional, detail oriented, very kind and quick. He was patient as we considered the scope of the project and drove me away from adding unnecessary scope (and cost, which would have been more money for him). He was extremely communicative, something I rarely see around the Cape and meticulous in his work and clean up. Believe me when I say I have high expectations that workers rarely meet - and Sam met them all."
