About Leighton A. White, Inc.

“We will always do our absolute best for our customers and clients – no exceptions.”

Dale White ~ President

Established in 1978, in Milford, New Hampshire, Leighton A. White, Inc. has grown from a small, part-time, custom tractor business to the corporation it is today. We have served the region for 46 years, specializing in commercial, industrial and municipal site work, construction and maintenance of communications sites, as well as specialty services including athletic field construction and maintenance.

Leighton A. White, Inc. has continued to expand our markets while remaining constant in fulfilling our customers’ unique requirements. We value a personal approach with our contractors and customers, and over the years we've established lasting relationships throughout Southern New Hampshire and beyond. Our exceptional service accounts for 80% of our business coming from repeat customers and their acquaintances. Much of the remainder comes from the recommendations and referrals of engineering firms and construction associations!

Leighton A. White, Inc.’s philosophy is best summed up by a favorite quote of Leighton’s that's framed and displayed prominently in his office:

“A competition for cheapness and a competition for excellence will always be strangers.”


Leighton A. White, Inc. is well known for our commitment to safety, having received the highest safety awards locally and nationally from Associated Builders and Contractors (ABC) since 1999. Based on our exemplary record, we were awarded the First Place National Safety Award in 2005 at a ceremony in Las Vegas. Leighton A. White, Inc. also received high honors by winning the 2008 Merit Place National Safety Award at a ceremony in Washington, D.C. This was awarded to our company out of 14,939 ABC contractor members. Such prestigious recognition is made possible by our commitment to education, safety guidelines, and proper equipment, along with our employees’ dedicated adherence to these recommendations. We know that safety is not only important to our employees and our “bottom line”, but it ultimately creates a safer environment for the end-user.


Through our four decades of business, Leighton A. White, Inc. has frequently donated time and resources to local causes. We’re proud of our efforts to give back to our community and make a difference. Below are a few recent area charitable events we participated in:

  • Supported the Milford Labor Day Parade
