They are excellent, and they work hard. Everything turned out perfect. They did some work that was out of the ordinary for them, and it still turned out well.

They were fast, they came out on a weekend, and they helped me pass an inspection.

It was super easy. They came out, they did the work, and it was on time. There was no hassle. There was one issue that I had, and they fixed it within 20 minutes. It was amazing.

I talked to two different women in the office, and they were super nice. The estimator who came out informed me what they were going to do and how much it would cost. It was great.

Company Philosophy

“No job is too big or too small for us—whether we’re replacing a section of fence that blew off in a storm or taking on a huge installation project, we take the same detail-oriented approach. At the end of the day, our goals are to make sure our clients are happy and create quality products at competitive prices that we’re proud to stand behind.”

Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for fence contractors that have earned the prestigious Diamond Certified award. For Hennessey’s Construction and Fence, the most effective way to keep clients happy is to take care of their needs before, during and after their projects. “We do what we say we’re going to do, and that’s why we have such stellar customer service,” says owner Ona Hennessey. “Our clients know they can trust us to follow through and provide them with great results.”

Hennessey’s Construction and Fence has been building, installing and repairing fences for residential and commercial clients in Contra Costa, Santa Clara, Alameda, and San Joaquin Counties since 2007. The company is renowned for its redwood fencing expertise, but it also has the training and equipment to install custom gates; chain link, wire, iron and picket fences; and more.

Unlike less experienced fence contractors that skimp on materials and labor in an effort to reduce their operating costs, Hennessey’s Construction and Fence exclusively uses premium materials and takes the time to do each job correctly. “We train our crew members differently because we insist on using the best possible products and techniques,” says Ms. Hennessey. “Also, we provide extra services that allow us to offer extended warranties, like exceeding the industry standards for setting fence posts and building runoff mounds around posts for better drainage.”

Another distinguishing feature of Hennessey’s Construction and Fence is the fact that it’s a woman-owned business. “I started working retail at a lumber company 20 years ago, and once I got to know lumber, I just fell in love with it,” explains Ms. Hennessey. “Once I had my daughter, I decided to get my contractor’s license so I could have more freedom and flexibility. I’m proud to offer my construction expertise to my community.”

Industry Info

If you’re in the market for a new fence, it’s a good idea to invest in a long-lasting product.

New fencing can be costly, and if you have a large yard or want a custom fence, the cost can go up quickly. So, when it comes to purchasing a new fence, it’s important to make smart decisions that make the most of your investment.

Choose better products
You could go with cheaper products, but experts say you won’t save much money in the long run. In fact, it could end up costing you more if your fence fails and you need to replace it sooner. That’s why savvy consumers choose quality lumber, composites and other materials that are designed to last. While your initial cost will be higher, products that stand the test of time have much more value. “You want to work with a contractor that uses hardwood and other materials that last a long time,” affirms Ona Hennessey, owner of Hennessey’s Construction and Fence in Brentwood. “To some people, a fence is just a fence, but if you’re spending the money, it should last 20 years instead of five.”

Insist on the best installation methods
Good materials go a long way toward building a fence that lasts, but careless construction can undo all of that. Contractors who skimp on materials, don’t use quality fasteners and don’t use industry-best installation methods can build fences that fall apart fast. Instead, make sure your fencing contractor selects and installs high-quality materials. Ask how they prevent posts from rotting and warping, learn whether they take steps to avoid water seepage and dry rot, and discuss whether their fences are constructed with gaps or overlaps.

Maintain your new fence
New fences are investments, and taking care of them will help them last longer. Ms. Hennessey recommends staining a new fence. “A stain isn’t only for aesthetics—it’s going to extend the life of your fence,” she says. “Also, waterproofing your fence will ensure the boards and posts don’t rot.” She also suggests making sure sprinklers aren’t directly hitting your fence and being careful with irrigation and vegetation located near fence lines.

Frequently Asked Questions

Q: How soon can you start my project?
A: Typically, we can start within two to four weeks of your initial call. However, we always leave some room in our schedule for dealing with storm damage. We also have a waiting list, so if we’re able to get to your project earlier that expected, we’ll let you know.

Q: Do you offer free estimates?
A: Yes. We’ll send a company representative to your property to discuss your project, take measurements and provide you with a written estimate.

Q: If I share a fence with my neighbor, can we have separate contracts and be billed separately?
A: Yes. We use DocuSign, so we can create different contracts that can be filled out separately. That way, you won’t be responsible for your neighbor’s portion of the fence.

Q: Can you help me determine city codes for fence height and materials?
A: Yes. We’ll tell you what your city allows and help you with the permit process.

Q: What will you do with my old fence?
A: We’ll haul it away and demolish it at no extra cost, and we’ll recycle the materials if possible.

Q: How can I maintain my fence?
A: Fences are investments, so it’s important to take care of yours so it lasts as long as possible. Stains aren’t just for aesthetics—they’ll extend the lifespan of your fence. Waterproofing your fence will ensure the boards and posts don’t rot. Make sure your sprinklers don’t directly hit the fence, and be careful with installing irrigation or planting trees near a fence line. If a post or board twists or breaks, call us so we can replace it.

Q: Why is redwood fencing so expensive?
A: The price of redwood has gone up immensely—about 30 percent over the past two years—and there can be limited availability. If cost is a concern, we can help you find good alternatives, including composites.

Q: Should I be concerned about using pressure-treated wood in my yard?
A: It depends on how it’s being used. For decking and underlayment, pressure-treated wood is a great option. There are better regulations now and arsenic is no longer used, so it’s safe for ground contact. However, we still don’t recommend using pressure-treated wood in planter boxes if you’re growing food.

Q: Can I choose a Green fencing option?
A: Absolutely. There are vinyl and composite fence options that look a lot like wood and are better for the environment. Some composites are even made out of recycled materials like milk cartons.
