Therma-Tru Fence Installation: The San Antonio Owner’s Guide
Therma-Tru fence installation in San Antonio typically runs $3,500 to $9,000 fully installed, depending on the panel style, linear footage, and post condition. We stock Therma-Tru-compatible gates, panels, and hardware on our trucks and can match most models same week. Most owners call us because a gate post has gone soft at the base, a panel has warped in the Texas sun, or the latch no longer catches after a season of San Antonio clay shifting under the footings.

If you’re reading this, you probably already know the part that failed. What you need now is a straight answer on the price and whether the fix will last. That’s what this page covers.
Which Therma-Tru Models This Applies To

Therma-Tru makes entry doors, but the fence and gate line is what San Antonio homeowners call us about. The compatibility question comes down to the hinge system and post spacing, not just the panel brand. Most Therma-Tru-compatible fence installations we do break into two groups: pre-hung gate panels that mount to 4×4 or 6×6 posts, and full-run panel systems where the gate and adjoining fence sections share the same rail profile.
The gotcha we see regularly: a homeowner buys a replacement gate panel online, then finds the hinge spacing on their existing post doesn’t line up. Therma-Tru gate frames use a mortise-style hinge pocket that sits 7 inches from the top and bottom rail, not the 6-inch standard you’ll find on a box-store gate. We carry both patterns and we’ll check your post before we quote anything. The OEM-versus-aftermarket decision is simple for us: for gate frames and latch hardware, we install OEM-spec because the tolerances matter. For fence panels themselves, a quality pressure-treated equivalent does the job at roughly 20% lower cost, and we’ll tell you which route makes sense before we order anything.

Signs Your Therma-Tru Fence Installation Is Failing
- Gate drags or won’t latch. This is the number one call. In San Antonio, clay soil expands and contracts with our wet-dry seasons, and that movement torques the post. The gate frame is usually fine, but the post has drifted out of plumb. If the latch throws but doesn’t engage, the post has crept a quarter inch or more.
- Soft spot at the bottom of the gate post. Water pools where the post meets the concrete footing, and after five or six Texas summers, rot starts. Push a screwdriver into the base. If it sinks in, that post is done.
- Panel rail separating from the stile. Therma-Tru panels are built tight, but sun exposure on the west side of a San Antonio yard will dry the wood enough that the rail-to-stile joint starts to gap. This is repairable early on. Left alone, the panel sags and pulls the whole run out of line.
- Rusted hinge screws or a sagging gate corner. If the top hinge screws are rusting, you have moisture working through the frame. The gate will start sagging toward the latch side within a season. Tightening won’t fix it, because the wood around the screw threads is already gone.
- Fence section leaning in a straight-line run. One failing post drags the sections attached to it. You’ll see a visible wave in the top rail line from the street. By the time you see the wave, at least one post below grade is compromised.

AfterReplacement Cost & What’s Included

In San Antonio, a full Therma-Tru-compatible fence installation or gate replacement runs $3,500 to $9,000. The spread comes down to three things: total linear feet, whether we’re replacing posts or working with existing ones, and whether the soil condition requires deeper footings. A single gate replacement with new hardware and a new post usually lands between $700 and $1,600. A full backyard run of 150 linear feet with multiple gates sits at the top of the range.
Every quote includes parts, labor, haul-away of the old material, and our workmanship warranty. The written price you approve is the price on the invoice, no change orders, no last-minute surprises. Luca Romano still walks the final lines himself before we pack up, checking that every gate swings true and every panel sits flush.
DIY or Call Us?
You can check the post bases yourself, confirm the hinge spacing, and measure your run. That’s useful. What we’d tell you to skip is resetting a gate post in San Antonio clay without a concrete footing that goes below the root line. A shallow set posts will lean again by next spring, and you’ll have spent a weekend and a few hundred dollars on a fix that doesn’t hold. Gate work also involves a panel under tension once the hinges load, which can pinch fingers or swing hard if the latch releases mid-job. We’d rather you call us. Luca built his reputation on the principle that the craft comes first, everything else follows, and a gate that doesn’t sag after two years is craftsmanship you can see. If you want to price it first, call (432) 547-6806 and we’ll give you a real number over the phone.
FAQs

A properly installed Therma-Tru-compatible fence with pressure-treated posts set in concrete typically lasts 15 to 20 years in San Antonio before the posts need attention. The panels themselves usually outlast the posts. Call (432) 547-6806 and we’ll assess what you’ve got before you spend anything.
A gate post with rot at the base needs replacing, though we can sometimes sister a post if only the top third is compromised. The honest answer depends on where the failure is, and we’ll tell you straight either way. Estimates are free.
Most single-gate replacements are done in a day. A full fence run of 150 linear feet usually takes two to three days, including haul-away and a final walkthrough with Luca. Call (432) 547-6806 for a schedule based on your exact yard.
We keep gates, panels, hinge sets, and latch hardware on our trucks for the most common Therma-Tru configurations, including the 7-inch hinge pattern. If we need something outside standard stock, we order it and install within the same week. Call (432) 547-6806 to confirm your exact part before you buy anything online.
