Boral Fence Installation: The San Antonio Owner’s Guide
Boral fence installation in San Antonio typically runs between $3,500 and $9,000 depending on linear footage, post setting depth, and the specific Boral product line you’re matching. We stock and install Boral-compatible fence panels and posts, and can usually have the right materials sourced within a few business days. Most San Antonio homeowners discover a Boral fence problem the same way: a panel cracks after a hard storm, a post shifts in clay-heavy soil, or a gate stops latching cleanly after years of heat cycles.
The thing about Boral fencing is that it’s engineered differently than wood. It’s a mineral-composite panel system designed to hold its shape through temperature swings that warp cedar and pine. That’s exactly why it matters in San Antonio, where we get triple-digit summers, sudden freezes, and soil that expands and contracts with the rain. When a Boral fence fails here, it’s rarely the panel itself. It’s usually the post footing, the gate hardware, or a section that was installed without accounting for our clay soil. Graham Stein and our crew have seen enough of these failures in neighborhoods like Alamo Heights, Stone Oak, and the King William Historic District to know what holds and what doesn’t.
Which Boral Models This Applies To
Boral fencing in the US market falls primarily under the TruExterior and Boral Composite Fence lines. TruExterior is the more common residential product: a poly-ash based panel that comes in board-and-batten, picket, and privacy styles with coordinating posts and gates. The panels are typically 6 feet by 6 feet or 6 feet by 8 feet, and the posts are either 4-by-4 or 5-by-5 depending on the gate load and wind exposure.
If you’re unsure which Boral product you have, check the inside of the gate frame or the bottom channel of a panel. Boral stamps their product code there. If that’s faded, measure the panel thickness. TruExterior panels run about 5/8 to 3/4 inch thick, consistently, which is one way to distinguish them from cheaper composite boards that flex more. One compatibility gotcha we deal with regularly: Boral’s fence system uses a specific post sleeve and channel design, and generic composite posts from other manufacturers don’t seat correctly. The panel-to-post tolerance is tight, which is good for stability but bad for mixing brands. We recommend OEM Boral components where they’re available, and we will only substitute a quality aftermarket part if it’s been tested against the same wind load and thermal expansion specs. We’re an independent contractor in San Antonio, not a Boral affiliate, so our job is to tell you honestly when OEM matters and when it doesn’t.
Styles & brands we work with
Signs Your Boral Fence Installation Is Failing
- Post lean at the gate line. The gate post takes the most repeated stress in any fence. If yours is leaning more than an inch out of plumb, the footing has likely broken loose in the clay soil. Boral posts are heavy, and once they start moving, they keep moving.
- Panel cracks near the bottom rail. In San Antonio’s heat, panels expand. If the original installer set the panels too tight against the post channels, that expansion has no place to go, and the bottom rail is where the stress concentrates. A hairline crack today is a split panel after one summer.
- Gate drags or sticks in the afternoon. Boral gates are heavy, and the hinges settle if the post wasn’t set deep enough. When the gate drags on the latch side, that’s a post or hinge problem, not a panel problem. Fixing the part that failed means correcting the footing, not just lubing the hinge.
- Visible gap between panel and post channel. Boral’s system relies on a tight fit. If you can see daylight between the panel edge and the post, the channel has pulled away or the post has rotated. This also lets moisture into the post, which accelerates the freeze-thaw damage.
- Warping near sprinkler heads or drainage low spots. Water pooling at the base of a Boral post, even a composite one, eventually works into the footing and causes heaving. We see this a lot in San Antonio yards with clay soil and automatic irrigation set too close to the fence line.
Replacement Cost & What’s Included
For a typical San Antonio backyard fence using Boral-compatible panels, the installed cost lands between $3,500 and $9,000. A smaller repair or a single gate replacement might come in lower; a full perimeter with new posts on all sides comes in at the higher end. The main cost drivers are linear footage, how many posts need to be reset or replaced, whether the old fence needs removal and haul-off, and access to the work area.
Every quote we write includes the parts, the labor, the post-setting material, the gate hardware, and the haul-off of old material. Before any work starts, we give you a written price. That price includes what the crew will protect while they work: drop cloths on floors inside the house where we pass through, shoe covers at the door, and quiet tools during family rest hours where possible. If the job requires adjusting spray patterns or moving a planter, we ask before we touch it. Graham Stein writes the scope of work down before a single tool leaves the truck, and the price you sign is the price you pay.

AfterDIY or Call Us?
There are a couple of things an owner can safely check before calling us. Look at the post bases for pooling water or sprinkler overspray. Check whether the gate hinges are tight. Look for visible cracks at rail ends. Those observations help us quote faster when you call.
What we do not recommend is pulling a Boral post or trying to reset a gate post yourself. Boral posts are heavy, and a gate post under tension can shift without warning. If the footing has failed, the fix means digging a new hole below the clay line, setting the post in concrete, and bracing it true while it cures. Get that wrong and you’ve doubled the repair cost. If you’re in San Antonio and the fence is leaning, cracking, or dragging, call us at (432) 233-0976 and we’ll come look at it. The estimate is free.
Key Takeaways
- Boral fence installation in San Antonio runs $3,500 to $9,000 installed, depending on footage and post condition.
- Most Boral failures in our area are post and footing problems, not panel failures.
- Boral’s fence channels are tight-tolerance, so mixing aftermarket posts from other brands usually creates more problems than it solves.
- We write the price before any work starts, and that price is the price you pay. No line items added after demo day.
FAQs
A properly installed Boral fence with correctly set posts should last 20 years or more in San Antonio’s climate. The panels are engineered to resist rot and insect damage. The posts and footings are the weak link here, and a post set too shallow in clay soil can fail in five to seven years. If the original installation didn’t account for soil movement, the panel can outlast the post by a decade. Call (432) 233-0976 and we’ll inspect the whole line before recommending repair or replacement.
In most cases, no. A cracked Boral panel has lost its structural integrity, and patching composite material usually looks worse than replacement and fails again. What can be repaired is the post or footing that caused the crack in the first place. If the panel cracked because a post shifted, we replace the panel and fix the post so the new panel doesn’t crack the same way. For an exact quote, call us at (432) 233-0976 and we’ll measure the affected section.
A typical single-side fence replacement in San Antonio takes two to three days from post digging to final cleanup. If we’re only replacing a gate or resetting a couple of posts, it’s usually done in a day. Material availability for Boral panels can add a few days if the specific profile isn’t in stock locally. Before we start, you’ll have a written schedule and a written price. We’ll also send a photo of the clean-up before the crew leaves, so you can see the yard was left right.
We stock common Boral fence components like post channels, gate hinges, and panel connectors on our trucks, and we source full panels and posts from San Antonio suppliers when the job calls for it. What we won’t do is substitute a generic post that doesn’t match Boral’s channel tolerance just to save a day. If the right part means waiting a few days, we tell you that upfront and price it honestly. Call (432) 233-0976 and we’ll confirm what’s available before you commit.
