It Started with One Truck & a Very Straight Line
Cornerpost began in 2001 when our founder, Luke Harmon † , started building backyard fences with a borrowed trailer and a stubborn rule: every post gets set like it has to hold for twenty years.
Twenty-five years later we’re a team of estimators, installers and project managers — but the rule hasn’t changed. We still string-line every run, still set corner and gate posts deeper and heavier than the rest, and still answer the phone when a customer calls five years later.
The name comes from the most important post in any fence. The corner post carries the tension of every run connected to it. If it moves, everything moves. That’s how we think about our work — and about the people who trust us with their property.

What We Stand For
Four Rules We Build by
Set It Deep
Post depth, footing size and concrete matched to soil, height and wind load — not a one-size-fits-all hole.
Straight Answers
Line-item quotes, honest repair-vs-replace advice and no surprise add-ons on install day.
Respect the Property
Lawn protection, marked sprinklers and a full clean-up. We leave yards the way we found them — plus a fence.
Stand Behind It
A written workmanship warranty and a real person who answers when something needs attention.

Neighbors Who’d Hire Us Again
“Temporary site fence was up in a day and they came back to install the permanent chain link and a cantilever gate at closeout. Reliable sub who shows up when they say.”
“Our 20-year-old fence was leaning into the neighbor’s yard. They pulled every old post, hauled it all away and had white vinyl up in two days. The neighbor asked for their number.”
“Eight-foot security fence with an automated slide gate and keypad. They coordinated the electrician and the gate operator, and trained our shift leads on the controls.”
