Therma-Tru Fence Installation: The Los Angeles Owner’s Guide
Therma-Tru fence installation in Los Angeles typically runs $4,130 to $10,620 installed, depending on the fence line footage, post depth, and whether we’re pulling permits through the city. Most owners discover their fence has failed the hard way: a gate that drags on concrete, posts leaning after a winter rain soaked the base, or hardware that’s sheared clean off under repeated wind load from the Santa Anas. The good news is we stock Therma-Tru-compatible gate hardware, post anchors, and replacement panels on our trucks for most residential fence jobs across Los Angeles. If your gate is sagging or your posts won’t hold square, this page tells you exactly what you’re looking at.
We’re an independent contractor in Los Angeles, not a Therma-Tru distributor or dealer. But we install against their spec sheets every week, and we know where their hardware tends to fail first in Southern California soil and sun. Therma-Tru’s fence line and matching gate systems are built around their door-grade composite frames and stainless hardware, which means the materials hold up, but the installation details make or break the job. In Los Angeles, that usually comes down to post embedment depth and how the gate hinges are shimmed.
Which Therma-Tru Models This Applies To
Therma-Tru’s residential fence systems ship in a few product families, and the hardware is not universal across all of them. The biggest compatibility gotcha we see in Los Angeles is mixing the gate hardware from the Classic-Craft composite fence line with the Benchmark steel-reinforced gate frames. The hinge bolt patterns are different by a quarter inch, and if you force it, the gate binds at the latch side. Before you order anything, pull the hinge and look for the part number stamped on the barrel. That number, not the fence panel style, is what matches the hardware.
The second thing to check is post diameter. Therma-Tru fence posts come in 4×4 and 5×5 schedule 40, and the 5×5 posts use a different base anchor and cap. If you’re replacing a post in Los Angeles and the original builder used a 4×4 in dry soil, we often move up to the 5×5 when we re-pour, because the Santa Ana wind lift on a six-foot gate is real. For panel replacement, stick with OEM Therma-Tru skins if you want color match across the fence line. If the rest of the fence has UV faded, a new OEM panel will be visibly brighter for the first season. Aftermarket panels fit, but the color tolerance is looser. We’ll tell you straight which one makes sense for your fence.
Styles & brands we work with
Signs Your Therma-Tru Fence Installation Is Failing
- Gate drags or scrapes on the concrete. This means the hinge posts have settled or shifted in the footing. In Los Angeles’s expansive clay soils, winter rain swells the ground and summer drought shrinks it, which slowly walks a post out of plumb. The gate was square when it went in; it is not square now.
- Posts lean at the base, not at the top. Leaning at the base points to a footing problem, usually concrete that was poured too shallow or without a proper post anchor. We see this constantly on Los Angeles hillside lots where fence lines run perpendicular to grade and surface water washes around the posts every winter.
- Gate latch won’t engage or binds. This is often a hinge problem disguised as a latch problem. When the top hinge wears even an eighth of an inch, the gate drops and the latch no longer lines up with the strike plate. Therma-Tru’s stainless hinge barrels are solid, but the frame screws holding them can pull loose in composite material over time.
- Rust streaks bleeding from the hinge area. Some production runs used zinc-coated steel hardware instead of stainless. Coastal air in Los Angeles, from San Pedro up through the Palisades, eats zinc hardware in three to five years. The fix is a full hardware swap to stainless, not sanding and touch-up paint.
- Fence panel rattles in the breeze. Composite panels flex under wind load and if the panel clips were over-tightened at install or cracked from UV exposure, the panel rides loose in the frame channel. It will not fall out, but it will sound like it every time the wind kicks up.

AfterReplacement Cost & What’s Included
For a typical Los Angeles residential fence repair or partial replacement, expect $4,130 to $10,620 installed. At the lower end, you’re looking at a gate hardware swap, one post re-footing, and panel re-clipping on a flat lot. At the upper end, you’re replacing a long fence line on a hillside, which means deeper footings, more material handling, and in some Los Angeles neighborhoods, a grading plan or permit requirement. Full fence replacement on a large lot can push past that range, but we give you a written price before any work starts, and that number does not move at the door.
Every installation includes removal and disposal of the failed section, new concrete for post footings, OEM or high-quality aftermarket hardware matched to your Therma-Tru part numbers, and a signed written guarantee under the 365-Day Done Right Promise. If the work fails within a year, we come back and correct it at no charge. That’s not a verbal promise; it’s the Garrison Standard, and it’s in writing on your invoice.
DIY or Call Us?
You can safely check a few things yourself: identify the hinge part numbers, check whether posts are plumb with a level, and note whether the footing concrete is cracked at the base. That’s useful information when you call us. What you should not do is dig out a leaning post on a hillside and try to re-set it in a single Saturday. Setting a post in Los Angeles soil requires getting below the expansive clay layer, usually 24 to 30 inches, and if the post is adjacent to an irrigation line or a gas line, a shovel can turn into a repair bill. Gate springs under tension also deserve respect. If the gate is heavy and the spring is loaded, that stored energy is not something to release by feel.

FAQs
The composite panels and stainless hardware should go 20 to 25 years in Los Angeles before the UV takes a visible toll, but the concrete footings and post anchors are the weak point. In clay-heavy soil, post settlement usually shows up between years 5 and 10. We can re-foot posts without replacing the panels, which is often the smartest spend.
Yes, if the post itself is fine and only the footing or anchor has failed. We excavate around the post, re-set it in fresh concrete with a proper anchor, and re-sleeve the post base. If the post is cracked or the composite is delaminating, we replace it. Call us at (903) 568-7222 and we’ll tell you which one you’re looking at.
Most hardware swaps are done in half a day: hinges, latch, strike plate, and any shimming to get the gate square. If the client wants new post anchors and re-footing, that’s a day to a day and a half depending on concrete cure time in Los Angeles summer heat. We schedule the work so the gate is operational the same day we set the posts.
We stock the common Therma-Tru gate hinge sets, stainless latch assemblies, post anchors, and panel clips for residential fence systems in Los Angeles. For rare or discontinued part numbers, we source OEM through our supplier network or match with a high-quality aftermarket equivalent, and we’ll show you the difference before you pay for it.
Whether you have one gate that will not close properly or an entire fence line that needs re-footing in Los Angeles, the first step is a free estimate. Call (903) 568-7222. A live person answers, you’ll get a written price, and the work is covered for a full year.
