Therma-Tru Fence Installation: The Los Angeles Owner’s Guide
Therma-Tru fence installation in Los Angeles typically runs $4,130 to $10,620, depending on the lineal footage, gate hardware, and whether we’re setting new posts in concrete or working with existing footings. We keep Therma-Tru-compatible post kits, gate frames, and latch hardware ready to measure and match on site, and most fence section replacements go from first measurement to finished install within a single workday.
The call usually starts the same way: a gate that no longer closes square, a post that leans after a winter rain, or a section of fencing that pulls away from the house. Los Angeles soil does a number on fence lines – the clay expands in the wet season and shrinks through the summer, which slowly works posts out of plumb even when the lumber itself is sound. Therma-Tru fence products are built to handle weather, but no fence line is stronger than the footing underneath it.
Which Therma-Tru Models This Applies To
Therma-Tru doesn’t sell a single fence line under one name – most of what we see in Los Angeles are Therma-Tru porch post wraps, gate frames, and rail systems that got matched to a fence or deck project, usually alongside a Therma-Tru entry door. The compatibility question matters because Therma-Tru post wrap dimensions are specific: the 4×4 wraps are built for a true 3-1/2-inch post, and the 6×6 wraps need a 5-1/2-inch post. If the rough post underneath is off by even a quarter inch, the wrap won’t seat cleanly and the fasteners will bind.
The fastest way to identify what you have is to look for the Therma-Tru marking etched into the bottom edge of the post wrap or the underside of a gate rail cap. If that marking is gone, measure the inside opening of the wrap, not the outside face – that inside dimension is the post size the system was engineered for. For gate frames, check whether the hinges are mortised into the frame or surface-mounted. Therma-Tru’s mortised hinge pockets are cut to a specific depth, and generic replacement hinges from a big-box store sit proud of the pocket, which throws the gate off its swing. We specify OEM hinge sets for Therma-Tru gate frames whenever they’re available, and use a machined aftermarket equivalent only when the original is discontinued.
One note worth stating plainly: Elmstead Remodeling is an independent Los Angeles contractor. We are not affiliated with Therma-Tru, and we don’t represent ourselves as a factory service provider. What we offer is measured, matched, and installed work using the same dimensional standards Therma-Tru products are built around.

Signs Your Therma-Tru Fence Installation Is Failing
- Gate drags on the latch side or swings open on its own. The hinge posts have come out of plumb, usually because the concrete footing wasn’t deep enough for Los Angeles soil movement. Tightening the hinges won’t fix a post that’s leaning – the post itself has to be reset or the gate re-hung on a new pivot.
- Post wrap gaps at the seams. Wood expands and contracts with moisture, and over a few Los Angeles wet-dry cycles the wrap seams can separate. This is usually a fastener issue rather than a material failure, but if the wrap has pulled away, water is getting behind it.
- Rust stains bleeding from hinge hardware. Coastal air moves inland further than most people expect, and standard steel hinges near the 405 or up in the hills will corrode before their rated lifespan. Therma-Tru’s coated hardware holds up better, but once rust stains appear, the protective coating is gone.
- Fence rail sag between posts. Rail span was set for a post spacing that doesn’t match what was actually built. We see this on Los Angeles hillside lots where crews stretched the spacing to accommodate uneven grade. The fix is adding a mid-span post or stepping the rail down, not bracing.
- Latch binds after a hard rain. The gate frame has swelled against the latch pocket. This is more common with solid gate panels than with ventilated frames, and the real fix is re-planing the strike edge and re-sealing the cut, not shaving the latch.

AfterReplacement Cost & What’s Included
In Los Angeles, a Therma-Tru fence installation – meaning new post wraps, gate frame, latch hardware, and the fencing sections themselves – runs $4,130 to $10,620 as a complete installed job. The range is driven by three things: lineal footage (a 40-foot side yard and a 100-foot property line are different jobs), whether we’re setting new posts in concrete or re-skinning existing framing, and gate count – each gate adds hardware, a frame, and swing adjustment time.
Every quote is written before work starts, and the written price is the price. That means the line items spell out the exact Therma-Tru or Therma-Tru-compatible components by dimension, the concrete and footing depth if applicable, and the labor for post setting, section hanging, and gate adjustment. If the scope changes mid-job because we discover rotted framing behind a wrap, we stop, show you what we found, and put the new number on paper before proceeding. The Cedarwell Care Promise is in effect on every project: shoe covers at the door, drop cloths on any interior path, a photo of the clean-up before we leave, and the 365-Day Done Right Promise behind the finished fence line.
DIY or Call Us?
There are things an owner can safely inspect: check whether posts are plumb with a level, look for gaps at wrap seams, test the latch throw to see if it seats fully. Those observations help us quote faster. What goes wrong with DIY on fence work is usually the footing – digging a new post hole in Los Angeles means knowing how deep the clay goes and how much concrete the hole actually needs, and a post set 18 inches deep in expansive soil will be leaning again in two seasons. Setting a gate to swing true requires the hinge posts to be dead plumb in two directions simultaneously, and once concrete starts to set, you don’t get a second adjustment pass.
If the work involves any post that carries a gate, or any wrap that’s separated enough to expose the structural post beneath, we’d rather you call us before the post rots or the gate tears its hinges. Fence work doesn’t have the dangerous high-tension components that a garage door spring has, but a sagging gate can drop suddenly when the hinge bolts finally pull, and that’s a hand and finger hazard. Call (949) 850-9896 and we’ll put your measurements in front of the crew before we even schedule the visit.
FAQs
With properly set concrete footings and the original Therma-Tru hardware, expect 15 to 25 years from the structural components; the post wraps and finish surfaces will show sun and moisture wear sooner, especially on west-facing exposures. We see the footings fail before the Therma-Tru product does. Call (949) 850-9896 for an assessment of what’s actually wearing on your fence line.
Yes, in about two-thirds of the Los Angeles fence jobs we see, the fix is resetting a few posts and re-hanging a gate rather than a full replacement – the decision comes down to whether the framing behind the wraps is still sound. We’ll tell you honestly if repair is throwing good money after bad. Call (949) 850-9896 and we’ll walk the line with you.
Most single-section replacements – one post, one section of fencing, one gate re-hang – are completed inside one workday from the time we start digging to the time we sweep up. Multi-post resets or full property-line work runs two to four days depending on the concrete cure time before we hang weight on the posts. Call (949) 850-9896 for a written schedule based on your specific scope.
We stock common Therma-Tru-compatible post wraps in 4×4 and 6×6 dimensions, gate hinge sets, and latch hardware on the truck, and we can source less common sizes from our Los Angeles suppliers within a couple of business days. If we need to order a discontinued component, we’ll tell you the lead time in writing before any work is scheduled. Call (949) 850-9896 and we’ll confirm availability for your measurement.
Key takeaways: Therma-Tru fence installation in Los Angeles runs $4,130 to $10,620 installed; the written price is given before work starts and doesn’t move; failures are usually footings and hinges rather than the Therma-Tru product itself; and most single-section work happens same-day.
