Therma-Tru Fence Installation: The Dallas Owner’s Guide
Therma-Tru fence installation in Dallas typically runs $3,500 to $9,000 for a complete perimeter, depending on linear footage, gate hardware, and site prep. We stock Therma-Tru-compatible posts, rails, and gate kits on our trucks, and most Dallas jobs are completed in two to four days. Owners usually discover a problem after a storm or a hard freeze: a gate starts dragging, a post leans after heavy rain, or a RailLatch no longer catches. By the time you’re searching for Therma-Tru parts, the failure has usually been quietly developing for months.
What we see most often in Dallas is moisture working into post footings during our wet springs, then the summer heat baking the soil into something closer to brick. That cycle wrecks posts long before the visible parts of the fence show wear. The good news is that Therma-Tru’s composite rail and picket system is built for this climate. The bad news is that a DIY post replacement almost always becomes a full fence redo if the first hole isn’t dug and set correctly. We’ll cover what’s worth checking, what’s worth replacing, and what a straight number looks like before you call.
How Much Does Therma-Tru Fence Installation Cost in Dallas?
Plan on $3,500 to $9,000 for a full Therma-Tru fence installation in Dallas, with most residential jobs landing between $4,500 and $6,500. The spread comes down to three things: linear footage, how many gates you need, and what the ground looks like once we start digging. Dallas clay is unforgiving. If your yard sits on the black gumbo common in East Dallas and parts of Oak Cliff, every post hole fights us. If you’re in North Dallas or Richardson with better-drained soil, the work goes faster and the price lands on the lower end of that range.
Here’s how the numbers break down:
- Base perimeter fence (150 linear feet, no gates): $3,500 – $5,000
- Perimeter with two pedestrian gates: $4,500 – $6,500
- Large property with double driveway gate: $7,000 – $9,000
- Partial fence replacement (one side, existing posts reused): $1,800 – $3,200
These are installed prices, parts and labor together. We use Therma-Tru spec-compatible posts, rails, pickets, and gate hardware. You’ll see the material cost as its own line item. We don’t bury it. You should know who is coming, what it costs, and what happens if something goes wrong, before we ever pick up a tool. On fence work, that means a written price with the post depth, concrete mix, and gate hardware listed outright.

Which Therma-Tru Models This Applies To
Therma-Tru doesn’t manufacture fence panels under its own brand the way it makes doors. What it does make is the TruVista and TruWeld composite railing systems, plus the hardware ecosystem around them, and those components show up in residential fence installations throughout Dallas. The TruVista line is the one you’ll most likely have if your fence looks like wood but never needs staining. TruWeld is the heavier profile, used more often around pool enclosures and commercial perimeters. Both systems use a 2×4 or 2×6 composite rail with stainless steel brackets and post skirts that lock into 4×4 or 5×5 posts.
Here’s the compatibility gotcha most Dallas homeowners hit: the TruVista rail profile changed slightly in 2019. Old-stock brackets from before that year will not seat a current production rail without shimming, and shimming a bracket on a fence that moves with Texas wind is a bad plan. If your fence went in before 2019 or you bought the house from someone who installed it, take a photo of the bracket and measure the rail width before ordering anything. OEM Therma-Tru parts are worth it for brackets and gate latches. For posts and post skirts, a quality aftermarket equivalent is fine, but only if the profile matches spec-for-spec. A post that’s an eighth-inch narrow lets the skirt rattle and lets water straight down the middle of the post sleeve.
We also stock KraftMaid, Cambria, and Silestone parts for interior projects, but fence work is Therma-Tru-specific. You identify your system by looking at the inside face of any bracket for a molded part number, or by measuring the rail: TruVista rails are 5.5 inches in height, TruWeld are 7 inches. That measurement alone tells us what we’re working with before we roll a truck.
Signs Your Therma-Tru Fence Installation Is Failing
- The gate drags on one corner but only in the afternoon. The post has shifted out of plumb, usually the hinge post. Dallas’s freeze-thaw cycle and clay expansion push posts out of position by fractions of an inch at a time. By the time a gate drags, the post is typically 1 to 2 degrees off and the concrete collar needs to be cut and reset.
- Water pools around the base of a post after rain. Post skirts that weren’t sealed at the sleeve seam let water in. In Dallas, a wet spring followed by a 100-degree August steams the inside of that sleeve and starts the rot that kills the post from the inside out.
- Rail brackets are showing rust streaks down the post face. Therma-Tru’s stainless brackets are the OEM standard, but aftermarket zinc brackets from big-box stores corrode within two to three years in Dallas humidity. Rust streaks mean the bracket is already losing structural grip.
- You hear a rattle from the fence line when the wind picks up. That’s the rail-to-bracket tolerance opening up, usually because a bracket has loosened or sheared a screw. Wind loads on a six-foot fence are serious, and Dallas gets real wind in spring. A rattling rail is load shifting to the remaining fasteners.
- Post skirts are lifting at the base or cracked at the corners. The skirt took a hit from a lawn mower or the ground heaved under it. Once the skirt lifts, lawn sprinklers and soil moisture work their way up the post sleeve year-round.

AfterReplacement Cost & What’s Included
A Therma-Tru fence post replacement in Dallas runs $400 to $800 per post, fully installed, including concrete, post, skirt, and bracket re-seat. A full rail and hardware swap on one fence side runs $1,500 to $2,800. A whole-fence replacement with new posts, rails, pickets, and gates is the $3,500 to $9,000 figure we hit up top. The range is driven by post depth requirements, the number of gates, and whether we’re cutting out old concrete or setting into fresh ground. Dallas is flat enough that grade changes are rarely an issue, but tree roots and old fence lines add digging time in older neighborhoods like Lakewood and Preston Hollow.
What’s included on every fence job: labor, parts, concrete and footing materials, debris haul-away, and a written line-item breakdown. We state the guarantee terms plainly. 365 days from the completion date, if the work is not right, Mason Remodeling makes it right at no cost. That’s the 365-Day Done Right Promise, and it covers the installation, not just the parts.
DIY or Call Us?
Fence work doesn’t carry the same danger as a high-tension garage spring or an electrical panel, so a careful homeowner can do a visual inspection without risk: check posts for plumb with a level, look for rust at the brackets, and wiggle each rail to see if it moves. What we’d tell you not to attempt is pulling a post out of Dallas clay by hand. Setting a new post requires digging below the frost line here, which in North Texas is shallow but still matters, and tamping a proper concrete collar. Get the depth wrong and the next spring rain leans that post over. Get the mix too dry and the post cracks its sleeve when the concrete cures. Get it too wet and you’ve made soup.
Isaac Pruett has walked too many Dallas yards where a previous homeowner’s weekend post fix left a leaning fence within a year. The repair costs more than the original post. If you want to check the fence yourself first, we’ll never talk you out of that. If you want us to make the call, call (432) 302-8761 and we’ll come look. The estimate is free, and you’ll get a written number before you decide anything.
FAQs
A properly installed Therma-Tru fence lasts 20 to 25 years in Dallas, with the composite rails and pickets outlasting the posts. Post footings usually fail first, which is why post sleeve sealing and concrete collar depth matter more than the visible parts. Dallas’s freeze-thaw and wet-dry clay cycles are harder on posts than the composite itself.
In most cases, yes. Single posts, rail sections, brackets, and gate hardware can all be repaired or replaced without touching the rest of the fence. We’ll tell you honestly when a full replacement is smarter: if three or more posts are out of plumb, or the rails have been loosening for long enough that brackets have wallowed out the composite, the repair bill gets close to replacement cost and you’re better off starting fresh. Call (432) 302-8761 and we’ll give you a straight answer after looking at it.
Most Dallas fence installations take two to four days from first post hole to final gate adjustment. Weather is the variable, and spring rains in Dallas can push the schedule by a day or two. We don’t leave a fence half-dug and we don’t work around storms if it means setting concrete in standing water.
We stock the common Therma-Tru parts on the truck: brackets, post skirts, gate latch kits, and rail hardware for TruVista and TruWeld systems. If your fence needs a less common profile or a discontinued bracket, we source it directly and show you the part cost on the written estimate before any work starts. You won’t be guessing at delivery windows.
