Boral Fence Installation: The San Antonio Owner’s Guide
Boral fence installation in San Antonio typically runs $3,500 to $9,000 for a full perimeter installation, depending on linear footage, terrain, and whether we’re pulling old posts or setting new ones. If you’re looking at a failed Boral post or cracked rail rather than a full install, we can often replace the failed component for far less. Most San Antonio owners discover the problem the hard way: a post snaps at ground level after a spring storm, or a rail pulls loose where the ground has shifted. Boral is engineered to resist rot and termites, but no product survives bad post-depth decisions or drainage issues. If your fence is leaning, splitting, or pulling apart at the seams, you’re on the right page. Call (254) 269-5071 and we’ll get you a written price before any work starts.
Which Boral Models This Applies To
Boral manufactures their fence boards and posts across a few distinct product lines, and the compatibility details matter more than most suppliers let on. The most common residential lines in San Antonio are Boral TruExterior boards (nominal 5/4 x 6 and 5/4 x 4 profiles, with a pronounced wood-grain texture) and Boral vinyl fence panels, which use a different post system entirely. If you’re unsure what you have, look at the end grain: TruExterior is a dense composite with a gray-green tint at the cut edge; vinyl is hollow or ribbed. The big compatibility gotcha is this: Boral TruExterior boards are dimensionally thicker than standard cedar pickets, so they require posts set at specific spans and rail channels sized to accept the thicker profile. A contractor who treats them like generic composite board will install a fence that sags within two seasons. We stock both Boral OEM rails and posts and quality aftermarket equivalents where they match spec. We’re an independent installer, not affiliated with Boral, which means we’ll tell you plainly when a less expensive rail will do the job and when you truly need the OEM part.
Styles & brands we work with
Signs Your Boral Fence Installation Is Failing
- Post lean of more than 5 degrees. This almost always traces back to insufficient embedment depth or a post set without gravel drainage at the base. San Antonio’s clay-heavy soil expands and contracts with moisture, and a shallow-set post will walk out of true within two or three seasons.
- Cracks at the rail-to-post connection. Boral’s composite material is dense, but it still expands and contracts with temperature swings. San Antonio’s 100-degree summers followed by sudden cold snaps put real stress on fastener points. If you see hairline cracks radiating from screw holes, the rail is near the end of its useful life.
- Ground-level post rot or crumbling. This is the one we see most in older San Antonio neighborhoods like Terrell Heights and Jefferson. Even rot-resistant Boral posts degrade when they sit in standing water. The failure looks like flaking, spongy material right at the soil line.
- Sagging rails between posts. When rails dip visibly between posts, the span is too long for the load, or the rail channels were undersized at install. This is a structural issue, not cosmetic, and it usually worsens quickly once boards start pulling loose.
- Loose or popping fasteners. Boral boards hold fasteners well when installed with the right screws, but wrong fastener choice – wood screws instead of composite-rated screws – is a common cause of early failure. Screws that back out are a warning sign, not a one-off annoyance.

AfterReplacement Cost & What’s Included
Boral fence installation in San Antonio typically lands between $3,500 and $9,000 for a full installation, depending on linear footage, gate count, and the condition of the ground where we’re setting posts. A partial repair – say, replacing three failed posts and re-securing rails – usually runs well below that range. What drives the price: post-hole depth in San Antonio’s rocky caliche soil (harder digging than you’d hit in other Texas markets), Boral’s thicker board profile requiring longer fasteners and wider rail channels, and whether your existing concrete footings can be reused. Every quote we write includes the parts, labor, post removal and disposal, concrete set material, and the gate hardware. You get a written line-item price before we unload a single tool. Our work on your Boral fence is covered by the 365-Day Done Right Promise: if anything we install fails within a year of the completion date, we come back and make it right at no cost to you.
DIY or Call Us?
Here’s the honest split. You can safely inspect your Boral fence yourself: walk the line, check for post lean, look for cracks at fastener points, and note any drainage pooling at the base of each post. That kind of inspection tells you what’s wrong. The actual repair is a different animal. Pulling a failed post means digging out whatever footing was set, breaking up concrete around embedded hardware, and setting a new post at the correct depth for San Antonio’s soil conditions – typically 30 to 36 inches, below the frost line and into stable ground. A fence that carries wind load across the line is not a safe place to learn on the fly. If a post is failed, the fence is structurally compromised, and a panel coming loose in a good San Antonio wind gust can damage property or hurt someone. The safe move is to let us handle the repair while you watch the process from the porch. Call (254) 269-5071 and we’ll send a technician with a name and photo before they arrive.
FAQs
A properly installed Boral fence in San Antonio should last 20 to 30 years, far longer than cedar or pine, provided the posts are set deep enough and the drainage at each post base is correct. San Antonio’s clay soil and seasonal moisture cycles shorten lifespan most when posts are set shallow or without gravel drainage. Call (254) 269-5071 and we’ll inspect what you have before recommending replacement.
Yes, in most cases we can replace the failed posts, rails, or individual boards without tearing out the entire fence, as long as the remaining structure is sound. The call is made post-by-post after we see the condition at ground level. If you’re not sure, call (254) 269-5071 – estimates are free.
A full Boral fence installation on a standard San Antonio lot takes between one and three days, depending on linear footage, gate count, and the digging conditions in your specific soil. Partial repairs are usually same-day or next-day. We’ll give you a specific timeline in writing before work begins.
Yes, our San Antonio crews carry Boral rails, posts, and matching fasteners on the truck for the most common profiles, along with aftermarket equivalents that meet spec where they make sense. That means most repairs we diagnose can be completed without a second trip.
