​Barron Brothers Development has been in the excavation business for over 30 years.

Along with the large commercial projects, we also specialize in house lot development, driveway repairs and septic installations.

Our retail facility opened on Route 11 in Farmington almost 20 years ago.  Since then, we have continued to grow the business by adding new products every year.



In the past several years we have done a lot of work at Pease ANG, including work on the runways!  We also do a lot of work with the local towns and cities.
