About Us

Harrington and Sons has grown from a small general contracting and paving company, begun in 1958, into the areas most experienced providers of construction and landscape services. Harrington oversees projects from small masonry and landscape maintenance jobs to large site development projects.

The company was founded in 1958 by a young William Harrington Sr., in an era where business was done with a handshake and a verbal commitment. The company’s focus was primarily General Contracting and Paving until 1990 when William’s son, John, came on board. With John’s vision, the business grew to add House Line Excavation into it’s portfolio of services. With the addition of quality, seasoned managers, the business continued to expand to include landscape Design and Build Services.

Such growth and expansion would not have been possible without an outstanding team of managers, each with an incredible resume of industry experience. Anchoring the House Line Excavation Team are Fred Zahn, Michael Roskie and Doug Bockoven. Mark Rafalco recently came on board as our Senior Project Estimator. John added Willie Mulvaney to the team in 2005, and with John, the two oversee the entire business and map out the company’s future.

Harrington’s experienced and seasoned managers approach each project with an eye for detail and success from start to finish. Whether it’s paving a driveway or an extensive site development project, all projects are completed within a schedule and customer satisfaction is paramount. We take pride in every project and in each of our divisions: Masonry, Landscape Design/Build, Paving, Remodeling and Site Development. We look forward to serving our customers and growing and evolving in an ever-changing and challenging industry.
