Therma-Tru Fence Installation: The Los Angeles Owner’s Guide
Therma-Tru fence installation in Los Angeles typically runs $4,130 to $10,620 for a full replacement with materials and labor included. We stock Therma-Tru-compatible fence panels, posts, and gate hardware on our trucks, so most jobs in the LA area get completed in a single visit. The usual discovery moment is a post that’s started leaning after winter rains, or a gate that suddenly drags against the ground because a hinge has pulled loose from softened wood.
You’ll know the failure when you see it: a section of fence line that’s no longer straight, a gate that won’t latch, or boards that have started separating at the seams. Los Angeles’s dry summers followed by sudden wet winters are rough on fence materials, and Therma-Tru’s composite and vinyl lines respond differently than wood. We’ll walk you through exactly what’s happening and what it costs to fix.
Which Therma-Tru Models This Applies To
Therma-Tru doesn’t make a traditional “fence” product line the way it makes entry doors, but many Los Angeles homeowners have Therma-Tru door and trim products integrated into fence gates, privacy screens, and yard entryways. The compatibility question is usually about the gate assembly: the hinge posts, the latch hardware, and the door slab itself if your gate was built with a Therma-Tru exterior door as the entry point.
The gotcha we see most often in LA: Therma-Tru door slabs come in standard widths of 30, 32, and 36 inches, but fence gate openings are frequently framed at non-standard widths to match existing fence lines. If your gate opening measures something like 34 inches rough, an off-the-shelf Therma-Tru slab won’t fit without re-framing the opening or ordering a custom width. We measure the rough opening and the hinge placement before quoting anything, because a gate that’s even 1/8 inch out of square will sag within months. For fence-specific components like posts and rails, we use quality aftermarket equivalents matched to your existing material, not Therma-Tru-branded parts, since Therma-Tru’s catalog focuses on door systems rather than fence lines. This is the honest answer: an OEM Therma-Tru slab for the gate is worth it; OEM fence posts aren’t a thing, and paying for a “branded” post is wasted money.
Styles & brands we work with
Signs Your Therma-Tru Fence Installation Is Failing
- Gate drags or scrapes the ground when opening. The hinge screws have pulled loose from the post, or the post itself has started rotating in its footing. In Los Angeles clay soil, winter moisture makes footings shift, and a post that was plumb in August can be 2 degrees off by February.
- Visible gaps between the gate slab and the fence line. The gate was hung level but the fence posts on either side have settled unevenly. You’re seeing the difference in settling, not a hinge problem.
- The gate latch no longer lines up with the strike plate. Same root cause as above. Shimming the latch is a temporary band-aid; the post movement continues until the post is reset or replaced.
- Therma-Tru door slab shows swelling or cracking at the bottom edge. Water is wicking up from ground contact or standing water at the gate base. Fiberglass and composite slabs resist rot better than wood, but the bottom rail seal fails first in LA’s wet-dry cycles.
- Post wobbles when you push on it, but the gate still works. The post footing has failed below grade. This is the one we tell people not to ignore, because a leaning post transfers stress to the hinges and the slab, and a gate that falls can injure someone.

AfterReplacement Cost & What’s Included
In Los Angeles, you’re looking at $4,130 to $10,620 for a complete Therma-Tru fence gate and surrounding fence section installation, depending on linear footage, post condition, and whether we’re reusing your existing slab or installing a new Therma-Tru door unit. A single gate replacement with new posts and hardware typically lands in the lower third of that range. A full fence line with multiple gates, new footings, and a Therma-Tru door slab at the entry point climbs toward the top.
Every quote we write in Los Angeles includes the parts, the labor, the concrete for footings, hardware, debris hauling, and any disposal fees. Nothing gets added later. We give you the written number before any work starts, and it doesn’t change unless you change the scope. The work is covered for 365 days from the completion date under our Done Right Promise. If something’s not right within that year, we return and fix it at no charge.
DIY or Call Us?
You can safely inspect a few things yourself: check whether the gate is dragging, look for visible screw pull-out at the hinges, and see if the post moves when you push it. But resetting a post, re-hanging a heavy Therma-Tru slab, or re-aligning a gate that’s been sagging for months is not a weekend project. A gate slab that comes off its hinges can cause serious injury, and a post that’s rotted below grade needs a proper footing replacement, not more shims.
We’re also honest about the part where LA’s soil makes this harder than it looks. The clay expands and contracts with the wet season, and a footing poured wrong will move again within a year. If you want to know what you’re dealing with, call (213) 632-5711 and we’ll walk you through what we see. Estimates are free.
FAQs
A properly installed Therma-Tru gate slab lasts 25 to 30 years in Los Angeles, but the hinge hardware and post footings typically need attention every 8 to 12 years because of the wet-dry soil cycles. The slab itself rarely fails; it’s almost always the posts or hardware around it. Call (213) 632-5711 and we’ll tell you honestly whether you need a full replacement or just new hardware.
Yes, in many cases we can reset the post, replace the hinge hardware, and re-align the slab without replacing the Therma-Tru door unit itself. The exception is when the slab has water damage at the bottom rail or the post has rotted below grade, at which point replacement is cheaper than repeated repairs. Call (213) 632-5711 for a straight answer on which camp your gate falls into.
A single gate replacement or post reset is a one-day job in Los Angeles. A full fence line with multiple gates and new footings can run three to five working days depending on length and access. We’ll give you a written schedule with the quote, and we stick to it.
We stock Therma-Tru-compatible hinge sets, latch hardware, and gate slabs in common widths on our trucks, and we can order non-standard widths with about a one-week lead time. We also stock parts for KraftMaid, Cambria, and Silestone products, so if your fence work touches a kitchen or bath near the yard, we can handle that too. Call (213) 632-5711 and we’ll confirm what we have before you schedule.
Know who’s coming, know what it costs, know it’s guaranteed. Everything else is just noise.
