International Line Builders, founded in 1983, provides a full spectrum of electrical construction services, from transmission, distribution and substation work to inside electrical construction in numerous market sectors.
We specialize in overhead and underground distribution installation repair and maintenance, along with underground drilling to provide electric power line services. Through our division, ILB Electric, we also provide commercial electrical construction services, providing our customers with a complete package of construction services under one roof.
We have locations in Tualatin, Oregon; Newman Lake, Washington; Nampa, Idaho; and Corona, Riverside and West Sacramento, California. We are a preferred contractor in many of our markets, which means you can rely on us to get it done right the first time.
International Line Builders was created in 1983 by a lineman, Marley D. Martin. Just over a decade later, MDU Resources Group, Inc. bought International Line Builders to form its new subsidiary, MDU Construction Services Group.
Today, we are a full service electrical construction company. We’re still run by a team of linemen, electricians and industry experts. Throughout the West, we take care of our customers so they can take care of theirs.
