About
A family of electricians on Lancaster County farms
We started with milk house lights and barn fans for the neighbors. Grain bins came next, then the dryers that go with them.
Sixteen of us work out of the shop on Rohrerstown Road. The same family has answered the phone since the first job. We still walk the barn with you, write the plan down before we start, and turn the power off only when you say it is a good time.
Farm work first: barns, bins, shops and farmhouses
A written estimate before any work

Credentials
What we hold, and where to check it
Pennsylvania has no statewide electrician's license, so we show what the state does register, and our insurance. Programs and trade memberships go here once the owner adds them.

How we work
Three habits we keep
We ask about chores first
Milking, feeding and loading decide when the power can go off.
We write it down
The estimate, the outage window and any change are on paper before work starts.
We leave it labeled
Every panel is labeled and every farm gets a one-page drawing.

A walk-through is the best way to see how we work.
