Therma-Tru Fence Installation: The Jacksonville Owner’s Guide
Replacing or installing a fence system around a Therma-Tru entry door in Jacksonville typically runs $3,500 to $9,000 installed, depending on the material, linear footage, and what’s hiding under the old posts. We stock Therma-Tru-compatible fence components and hardware, and our crew is on a job like this the same week you call. Most Jacksonville homeowners find out their fence has failed the hard way: a post leans after a storm, a gate drags against the slab, or moisture has eaten through the bottom rail where it meets the ground.
Jacksonville’s humidity and salt air do not go easy on fence hardware. We see it all the time in neighborhoods like Riverside, Ortega, and San Marco: powder-coated steel that looks fine from ten feet away but is rusting through at the post-to-rail connection. The good news is that Therma-Tru designed their fence systems with real engineering tolerances, and when you install them the right way in Florida soil, they hold.
Which Therma-Tru Models This Applies To
Therma-Tru fence installation covers the composite and vinyl gate, post, and panel systems paired with Therma-Tru entry systems, including Classic-Craft, Fiber-Classic, and Smooth-Star door lines. The fence components are part of Therma-Tru’s exterior accessory line, and the compatibility gotcha that trips up a lot of Jacksonville homeowners is this: Therma-Tru fence post sleeves and gate kits are sized for specific rail profiles, and a post that fits a Classic-Craft installation will not always seat correctly against a Smooth-Star frame.
To identify what you have, check the door slab edge for the Therma-Tru label. It lists the model line and the build code. Then measure the fence rail channel width. Most Therma-Tru residential fence rails run a 1.5-inch to 2-inch channel, but the post sleeve inner diameter has to match that channel exactly or the gate will bind. We keep OEM Therma-Tru fence hardware on the truck for the common profiles and use quality aftermarket equivalents only where Therma-Tru specs allow. Bradford Remodeling Co Jacksonville is an independent service provider, not a Therma-Tru dealer, which means we are not tied to one supply line: we buy the part that fits your door, not the part that’s easiest for us to stock.

Signs Your Therma-Tru Fence Installation Is Failing
- Gate drags or sticks at the latch. The post has shifted out of plumb, usually because the original installer set it in a shallow concrete footing. In Jacksonville’s sandy soil, a post set less than 30 inches deep will move within two or three rainy seasons.
- Rust streaks running from post caps or hinge screws. Salt air and humidity, especially anywhere east of the St. Johns River or within a mile of the Intracoastal, corrode standard steel hardware. Therma-Tru specifies coated fasteners for exterior fence kits; if you see rust, someone substituted the wrong hardware.
- Bottom rail rotting or cracking at the hinge post. Moisture wicks up from the concrete or soil. Composite rails hold up better than wood, but the joint where the rail meets the post collar is the first place water gets trapped.
- Fence posts leaning after a hard storm. A properly set post in Florida needs a concrete collar that extends below the frost line and is domed at the top so water runs off instead of pooling around the base. If water pools, the post works loose.
- Loose or sagging top rail with no obvious damage. The rail brackets have stretched or the rail was cut an eighth-inch short at install, which puts constant tension on the post sleeves. That tension will quietly crack the post over time.

AfterReplacement Cost & What’s Included
In Jacksonville, a Therma-Tru fence installation or full replacement runs $3,500 to $9,000. That is the installed price, including the fence panels, posts, gate hardware, concrete for the footings, and labor to remove and haul the old fence if there is one.
What drives the range is linear footage, post count, gate count, and what we find when we pull the old posts. If the existing concrete footings are intact and the right size, we can reset new posts in the same holes and the job goes faster and cheaper. If the old contractor hit a root and poured a shallow, cracked collar, we are digging it out and pouring new footings. That is time and material. Every bid we give includes a written line-item price before work starts, and that price does not move at the door. The completed work is covered by our 365-Day Done Right Promise: if your fence fails inside a full year of installation, we come back and correct it at no charge. That is The Garrison Standard, and we put it in writing on every job.
DIY or Call Us?
You can safely inspect the hardware and watch for the signs listed above. You can even tighten a hinge screw if the post is still solid. We would stop you short of pulling and resetting a gate or entry post yourself. A leaning post that carries a full gate panel is under constant load, and when the bottom of that post lets go, the gate drops hard and can take the adjacent panel with it. That is an injury risk and a property damage risk, not just a fence problem.
If you have a post that has shifted out of plumb or a bottom rail that is splitting, call us at (904) 337-5929. We will come out, assess the post footings and rail condition, and give you a written price to set it square and level. Scope it right the first time – the job goes a lot smoother when nobody’s surprised.
FAQs
A correctly installed Therma-Tru composite or vinyl fence should hold 20 to 30 years in Jacksonville, with the main failure point being the post footings rather than the rail material. Salt air and humidity will corrode untreated hardware in 5 to 10 years, which is why we spec coated fasteners and seal every post cap joint. Call (904) 337-5929 if you’re seeing signs of movement sooner than that.
Yes, and in most cases a leaning post can be pulled, the footing inspected, and the same post reset with a proper concrete collar if the post sleeve itself has not cracked. If the sleeve has cracked or twisted at the rail channel, replacement is the honest fix. We’ll tell you which one you have and price it before any work starts.
Most straight fence installations with two to four posts and one gate take one to two days, including concrete set time for the footings. A full perimeter fence with six or more posts and multiple gates may run three to four days. We lock the schedule in writing when we give you the price.
We stock OEM Therma-Tru fence hardware for common rail profiles, including post caps, hinge sets, and gate latch kits, and we can source panels and full post kits through the same trade suppliers we use for Therma-Tru door installations. We also carry compatible hardware for KraftMaid, Cambria, and Silestone jobs, so the truck is rarely the bottleneck.
