Therma-Tru Fence Installation: The Dallas Owner’s Guide
Therma-Tru fence installation in Dallas typically runs $3,500 – $9,000 installed, depending on the post material, gate hardware, and whether we’re replacing an existing line or setting new posts from scratch. Most Therma-Tru fence systems we work on are paired with fiberglass or composite gate hardware that’s matched to the door style, and we stock the common post caps, gate brackets, and hinge sets on the truck. The call usually starts the same way: a gate that’s dragging on the latch side, a post that’s started to lean after a hard freeze, or a fence section that’s no longer square with the Therma-Tru entry door it was built to frame.
Which Therma-Tru Models This Applies To
Therma-Tru is primarily an entry door manufacturer, so when we talk about Therma-Tru fence installation in Dallas, we’re almost always dealing with fencing that’s been built around a Therma-Tru door system: fiberglass or steel entry doors with matching sidelights, transoms, or gate assemblies in the 36-inch, 42-inch, and double-door configurations. The fence hardware compatibility matters more than homeowners expect. Therma-Tru door slabs use their own hinge prep and latch bore specs, and when a fence gate is hung to match the entry door, the latch and strike alignment has to be shimmed to the door’s closed position, not just eyeballed. If the post is set even 1/4 inch out of plumb, the gate will bind against the Therma-Tru threshold and wear the weatherstrip within a season.
We’re an independent Dallas contractor, not affiliated with Therma-Tru. We install and service fences that surround or connect to Therma-Tru entry systems regularly, and the practical knowledge we bring is knowing which hardware failures are fence-related and which ones are door-related. That distinction saves homeowners money, because you don’t want to replace a $900 gate assembly when the real problem is a $14 hinge bushing.
Styles & brands we work with
Signs Your Therma-Tru Fence Installation Is Failing
- Gate drag on the latch side. This is the most common call we get. The gate post has settled or the hinge screws have loosened, and the gate is now rubbing against the Therma-Tru door frame or the fence picket. Left alone, it grinds the bottom edge and can damage the door’s weatherstrip.
- Post lean after a freeze-thaw cycle. Dallas clay soil expands and contracts hard through winter. Posts that weren’t set below the frost line or lacked proper drainage gravel will heave or lean within two to three years. In neighborhoods like Lake Highlands and Richardson, we see this pattern constantly.
- Rust staining around hinge screws. If the fence was built with cheap zinc-plated hardware instead of stainless or powder-coated, North Texas humidity will rust it fast. The tell is orange streaks running down from every screw head.
- Gate won’t latch without lifting. The gate frame has racked, meaning it’s no longer square. Therma-Tru door slabs are heavy, and a matching gate needs diagonal bracing or a turnbuckle to hold its shape. Without it, the latch misses the strike by a half inch.
- Loose post caps or split post tops. Water gets into the post through cracks or missing caps, then the freeze cycle splits the wood from the inside. By the time you see the crack, the post is already compromised.

AfterReplacement Cost & What’s Included
For Dallas homeowners, a Therma-Tru fence installation or fence repair runs $3,500 – $9,000. On the lower end, you’re looking at replacing gate hardware, resetting one or two posts, and re-hanging a single gate section. The upper end includes full fence replacement around a Therma-Tru entry system: new pressure-treated or cedar posts, all stainless hardware, a reinforced gate frame with diagonal bracing, and realignment to the door’s exact closed position.
What drives the price: post material (pressure-treated pine is cheapest, cedar runs 20 – 30% more), gate width (a double gate needs heavier hardware and sometimes a steel frame), existing concrete (removing old post footings adds labor), and whether we’re matching an HOA-approved style. A permit isn’t typically required for fence repair in Dallas, but if we’re replacing more than 50% of the fence line, the city may want a simple permit pulled. We handle that. The price we give you is the price on the invoice. If something fails inside a year, our 365-Day Done Right Promise means we come back and fix it at no charge, and we’ll put that in writing along with your estimate.
DIY or Call Us?
You can check a few things yourself before calling. Look at the hinge screws: if they’re loose, tighten them. Look at the gap between the gate and the Therma-Tru door frame: if it’s even top to bottom, the post is likely fine and the latch needs adjustment. You can also spray the latch mechanism with a dry graphite lubricant, which helps with sticking.
What you should not attempt is resetting a post or re-hanging a heavy gate by yourself. A Therma-Tru door slab can weigh 60 to 90 pounds, and a matching gate with framing is heavier. When a post comes out or a gate comes off its hinges, the stored energy releases fast, and that’s how fingers and toes get crushed. This is not a job to learn on. If the post is leaning or the gate is racked, call us at (940) 204-5368. Trevor Nash has been doing this since his LA Trade-Tech days, and he’d rather give you a number before he picks up a tool, because that’s the only way he knows how to start.
FAQs
A properly installed Therma-Tru-compatible fence with pressure-treated or cedar posts, stainless hardware, and drainage gravel at the base should last 12 – 20 years in the Dallas climate, with the gate hardware being the first thing that wears out. The two things that kill fences early here are clay soil movement and poor post drainage. We set posts below the frost line and pack with gravel, which is the difference between a fence that’s still square at year 10 and one that’s leaning at year two. Call (940) 204-5368 for a free estimate on your specific fence.
In most cases, yes. If the gate frame is solid and the posts are still set, we can replace hinges, latch hardware, post caps, and weatherstrip, re-square the gate with bracing, and have it working like new. Replacement makes sense when the posts themselves are split, rotted, or heaving. We’ll tell you which one applies to your fence before we quote anything.
A typical fence repair or single-gate re-hang takes one day. A full fence replacement around a Therma-Tru entry system takes two to three days, depending on the size of the line and how much old concrete has to be removed. You’ll get a defined arrival window when you schedule, and the date we give you is the date we show up. Call (940) 204-5368 to see our schedule.
We keep common stainless hinge sets, latch assemblies, post caps, turnbuckles, and gate bracing on the truck for most Therma-Tru-compatible fence systems. Special-order hardware, like oversized black-powder-coated hinges for a double gate, we can source within a few days. We also keep parts for other brands we work with regularly, including KraftMaid, Cambria, and Silestone.
