Company Profile

Hennessey's Fencing is a family-owned and operated business founded in 2007 by Ona, who learned the trade from the ground up while working for another fencing company. Based in Brentwood, CA, the company serves Contra Costa and Santa Clara counties with custom fencing, gates, decks, and patio covers for both residential and commercial clients. Ona started the company by door-knocking with flyers, and today the business thrives on referrals from families, friends, and satisfied customers. Hennessey's Fencing specializes in redwood fencing but also offers metal, chain link, wire, and vinyl options, along with specialty solutions like ranch fencing and retaining walls. The team handles deck construction, design, repair, and replacement, as well as automatic and manual gate installation and repair. Licensed and bonded (License #899814), the company backs its replacement work with a 7-year warranty. Ona's goal is to grow the business without sacrificing the quality and integrity that built its reputation. For Brentwood residents, Hennessey's Fencing addresses common local issues like leaning fences and post instability caused by dry soil by using deeper post holes, concrete footings, and moisture-resistant materials to ensure long-lasting stability. Located near landmarks such as the Brentwood Community Center and the Streets of Brentwood shopping district, the team knows the area well and provides reliable, neighborly service.
