Therma-Tru Fence Installation Nationwide

Therma-Tru Fence Installation: The Los Angeles Owner’s Guide

Therma-Tru fence installation in Los Angeles typically runs $4,130-$10,620 for a complete residential system, with most single-family projects in the $5,900-$8,260 range depending on linear footage and terrain. We stock Therma-Tru-compatible composite fence components and can typically schedule installation within 3-5 business days after the written quote is signed. Most Los Angeles homeowners first notice an issue when fence boards warp or fade unevenly after 5-7 years of direct sun exposure, or when posts loosen in our clay-heavy soils after winter rains.

Which Therma-Tru Models This Applies To

Therma-Tru manufactures fence systems under several product lines, and matching the right components matters for warranty coverage and structural compatibility. The most common in Los Angeles are the Captiva composite privacy series, the Barrington picket system, and the Chadwick horizontal board line sold through specialty dealers from 2018-2023.

To identify your system, check the inside face of the end post cap or the bottom rail for a stamped date code and series name. Captiva boards measure 5.5 inches actual width with a hidden fastener groove on one edge; Barrington pickets are 3.5 inches with a square shoulder. If your fence was installed by a previous owner without documentation, measure the board thickness - Therma-Tru composites run 0.875 inch, while competing brands often spec 0.75 inch. That one-eighth-inch difference affects every bracket and fastener.

We source OEM Therma-Tru components through authorized distribution, though in some cases we specify compatible third-party aluminum post sleeves or stainless steel brackets that meet or exceed the original spec. The decision depends on what’s actually failed: a faded board is cosmetic and any matching composite works; a cracked post base in seismic country demands the engineered load rating that OEM provides.

Signs Your Therma-Tru Fence Installation Is Failing

• Boards cupping or bowing outward. Therma-Tru’s composite expands lengthwise in heat; if installers set boards tight against posts without the manufacturer’s specified 3/16-inch end gap, summer thermal expansion forces the board to warp. We see this most in south-facing yards in Silver Lake and Echo Park where afternoon sun hits hard.
• Post leaning at the base after rain. Los Angeles clay soils expand when wet and shrink when dry. If the original installer backfilled with native soil instead of gravel and concrete to 6 inches above grade, the post loosens within two wet seasons. The fix isn’t shimming the post; it’s extracting and re-pouring the footing.
• Gate sagging or latch misalignment. Therma-Tru gates over 42 inches wide require a steel frame insert; without it, the composite top rail creeps downward over 18-24 months. The latch doesn’t “break” - the frame geometry shifts until the striker misses by half an inch.
• Color fading to gray in patches. This is UV degradation of the cap layer, accelerated by reflected light off pools or light-colored hardscape. Full replacement isn’t always necessary; we can often match and replace affected runs if we have the original color code.
• Rattling or clacking in Santa Ana winds. Loose fasteners in hidden-clip systems let boards move against the rail. The noise is the symptom; the cause is either under-torqued clips at install or thermal cycling that walked the screws out over time.

Replacement Cost & What’s Included

Complete Therma-Tru fence installation in Los Angeles runs $4,130-$10,620, with the typical 150-linear-foot suburban job landing near $6,800. The range reflects three variables: linear footage, terrain (level yard versus retaining-wall integration in the Hollywood Hills), and whether we’re replacing an existing fence or installing on raw ground.

Our written quote itemizes every line: composite boards by the piece, aluminum or steel posts, concrete footings, gates with steel frames, hardware, and labor. Under Clause 1 of the Haven Standard, that price is fixed. If we hit unexpected conditions - a buried irrigation line, a property line dispute - we stop, photograph it, write a change order, and no work proceeds until you sign it. That’s the discipline that has kept our projects within a few percent of the agreed number across 4,000-plus jobs since 2007.

The 365-Day Done Right Promise covers the installation. If a board warps, a post settles, or a gate drags, we make it right. The documented photo record from every visit is yours to keep, because if it’s not written down, it didn’t happen.

DIY or Call Us?

A homeowner can safely check the obvious: loose post caps, visible fastener heads, or a gate that needs hinge adjustment with a screwdriver. What we don’t recommend is attempting post replacement or footing work yourself. Fence posts in Los Angeles require excavation to 24 inches minimum depth, concrete mixed to 3,000 PSI, and awareness of underground utilities including the gas lines that run through most older neighborhoods.

We’ve also seen DIY attempts where the homeowner matched the board color to a photo instead of the actual faded fence, or used standard wood screws instead of the coated fasteners that Therma-Tru specifies for composite expansion rates. The repair looks right for six months, then the fasteners corrode and the boards split at the holes.

If you’re unsure what you’re looking at, call (213) 652-7670. We’ll come out, photograph what we find, and give you a written price before any work starts. The estimate is free.
