Built on Hard Work, Backed by 15+ Years of Experience

Allegiant Fencing was founded with a simple belief: every customer deserves a quality fence installed by people who take pride in their craft. What started as a small operation in Allenstown, NH has grown into one of Central and Southern New Hampshire's most trusted fencing contractors.

Over the past 15+ years, we've completed more than 327 projects across the region — from simple backyard privacy fences to large commercial enclosures. We've built our reputation one post at a time, earning referrals from neighbors, builders, and property managers who know they can count on us to show up, do the job right, and stand behind our work.

We're fully insured, and all of our products and installations are 100% Guaranteed under a 5-Year Warranty. We offer free estimates on every project. Whether you need a cedar privacy fence, a vinyl fence that lasts decades, or a commercial chain-link enclosure, we bring the same level of care and craftsmanship to every job.
