Therma-Tru Fence Installation: The Long Beach Owner’s Guide
Therma-Tru fence installation in Long Beach typically runs $3,500 to $9,000 installed, depending on linear footage, post condition, and whether we’re matching existing gate hardware. We stock Therma-Tru-compatible fence panels, post caps, and gate kits on our truck, so most installations in Long Beach are completed in one to two days. Most homeowners discover the problem the same way: a gate that suddenly drags across the concrete, a post that leans after a winter storm, or a panel that splintered where the dog keeps pushing against it.
We’re an independent contractor serving Long Beach and the surrounding neighborhoods, not a Therma-Tru dealer or affiliate. What we are is a crew that has installed enough Therma-Tru fencing in this coastal climate to know exactly how the salt air and the Santa Ana winds work on their composite rail systems. If you have a Therma-Tru fence that’s failing, Graham Stein and his crew can tell you what’s salvageable, what needs replacing, and what it will cost before any work begins.
Which Therma-Tru Models This Applies To
Therma-Tru sells fencing under a few different product lines, and the compatibility details matter. Their composite privacy fence panels come in 6-foot and 8-foot widths, with a tongue-and-groove profile that’s specific to the series. The Benchmark and TruChoice lines are the two we see most often in Long Beach backyards, particularly in neighborhoods like Los Altos and Bixby Knolls. The good news: Therma-Tru’s aluminum-reinforced posts are consistent across most of their fence lines, so post replacement is straightforward once we confirm the diameter.
The identification step is simple. Look at the back of a fence panel or the inside of a gate stile, and you’ll usually find a molded-in product code. If the code has faded or was painted over, measure the panel thickness. Therma-Tru composite fence panels run a true 1-inch thickness, which is slightly thicker than most aftermarket vinyl. That 1-inch profile means aftermarket panels often don’t seat correctly in the Therma-Tru post channels. We recommend OEM panels for any section that’s visible from the street, and we’ll explain where a quality aftermarket post cap or gate latch does the job without compromising the system.
Styles & brands we work with
Signs Your Therma-Tru Fence Installation Is Failing
- Gate drag or sag at the latch side. In Long Beach’s sandy soil, the post under the hinge side settles faster than the rest of the fence line. The gate then drops a quarter inch and the latch stops catching cleanly. This is usually a post reset, not a gate replacement.
- Wobbling posts at the panel joints. Composite panels are rigid, but the post bases set in concrete can loosen when winter rains saturate the ground and then dry out through our long summer droughts. A post that moves more than half an inch when you push it needs to be re-set before it cracks the panel corners.
- Panel splitting near the bottom rail. We see this mostly in yards with active dogs. The bottom rail takes body weight and claw pressure, and once the composite cracks, moisture gets into the internal channels. California’s dry-then-rain cycle accelerates the damage.
- Faded, chalky surface on the sun-facing side. Therma-Tru panels hold color better than vinyl, but nothing beats a decade of Long Beach sun. Surface oxidation is cosmetic at first. If the fade is paired with brittleness at the corners, the panel is near the end of its life.
- Loose post caps that collect water. Post caps are the first part to go. The UV-stabilized plastic gets brittle, and once a cap cracks or pops off, rain goes straight down the post interior. That water sits and works on the post base from the inside.

AfterReplacement Cost & What’s Included
For a typical Long Beach backyard fence, we quote $3,500 to $9,000 for Therma-Tru-compatible installation. The range reflects how much of the existing structure can be saved. A gate post reset with new hardware might land near the bottom of that range. A full perimeter replacement with new panels, posts, caps, and two gates lands at the top. Linear footage is the main driver, followed by whether the soil condition requires deeper post holes or additional concrete.
- Gate post reset with concrete and hardware: $350 – $650 per post
- Single panel replacement (OEM Therma-Tru-compatible, installed): $220 – $400 per panel
- Full fence replacement, typical 100 – 180 linear feet: $3,500 – $9,000
- Gate replacement with new hardware and post reinforcement: $700 – $1,800 per gate
Every quote includes the parts, labor, concrete, haul-away of the old fencing, and the written price before any work starts. We give you a line-item scope of work at the estimate, and that’s the number on the invoice. If we find a rotten post base after we start digging, we call, we explain it, and we show you what the additional cost would be before we touch it. No surprises added at the end.
DIY or Call Us?
You can safely check the post caps and look for cracked panels yourself. You can test gate sag by lifting the latch end of the gate an inch and watching how much play is in the hinge. What you should not do is try to reset a fence post in Long Beach without the right equipment. Our soil here alternates between sandy and clay-heavy depending on the neighborhood, and pulling a post means breaking up the original concrete footer. Without a post-hole digger, a level with a magnetic mount, and the patience to double-check plumb with every lift, you’ll end up with a post that leans again in six months. A fence toppling over in a windstorm is a safety issue, especially with kids in the yard. Call us at (562) 512-7086 before you dig.
FAQs
Therma-Tru composite fencing generally lasts 20 to 25 years in Long Beach before panel brittleness becomes a problem, though post bases often need attention at the 10 to 15-year mark due to soil movement. Call (562) 512-7086 for an honest assessment of what still has life in it.
Yes, in most cases a Therma-Tru fence can be repaired by replacing individual panels, resetting posts, or swapping out failed hardware. Our rule is to show you what’s salvageable and quote the repair separately from the replacement so you can decide with real numbers.
