Utility Overview

Pole Setting

Lighting Maintenance Inc. sets hundreds of utility poles each year. Once the useful life of a wooden utility pole runs out, it must be replaced. Otherwise, failure can occur causing widespread outages. Specialized equipment and highly trained linemen are used for these tasks.

Excavation, Potholing, and Locating

Lighting Maintenance Inc. utilizes the VacMaster 5000 pneumatic (air) vacuum excavation systems. The power and reliability of this equipment, along with the experience of our crews, allows LMI to locate, expose, and repair underground utilities quickly and efficiently.
We locate utilities electronically using state-of-the-art equipment, such as the RD7000. Locating cables in large underground networks is becoming increasingly complex. Ground distortion effects, caused by differing soil types and proximity to other conductors, make the operator’s job more difficult and time-consuming.


Lighting Maintenance Inc. installs primary and secondary duct banks, directional drill conduits, junction boxes, pedestals, transformer pads, manholes, hand boxes, and poles for several utility companies. Some of these utility companies include Delmarva Power, SMECO, Dominion Power, and Pepco.

Street Lighting

Lighting Maintenance Inc. executes street lighting maintenance and repair for utilities. We perform group replacement of lamps, photo cells, and, when appropriate, entire fixtures. We repair and/or replacement of damaged poles, resetting of knocked down poles, concrete bases, and cables underground and in the pole shaft. If an outage is the result of no-current, then we trace the circuit, locate the fault, excavate, repair, and backfill.

Fault Locating and Repair

If there is a failure in an underground electrical line, it is more difficult to locate. With an overhead line, you can see that a tree has brought down a line, and you know exactly where the failure is located. LMI has made many repairs to overhead lines in recent years.

Many homes, businesses, and street lights are fed through underground electrical lines. When a fault occurs, we must bring in special tools and equipment to locate and repair the fault, restoring power to the customer.
