Oldcastle Fence Installation: The Los Angeles Owner’s Guide
Oldcastle fence installation in Los Angeles typically runs $4,130 to $10,620 for a complete run, and yes, we stock the line posts, panels, and gate hardware for most Oldcastle concrete and vinyl systems on our trucks. Most homeowners call us after a section starts leaning, a gate drags against the concrete, or a post cracked at the base after a hard Santa Ana wind season. You’ll get a written price before we touch anything, and the crew that shows up will have been introduced to you by name and photo before they ever pull into your driveway.
We’re an independent Los Angeles contractor, not affiliated with Oldcastle, but we install their systems every week because the product holds up better than most in this climate when the posts are set right. Dry soil, relentless sun, and the occasional earthquake put real stress on fence lines here. When a post fails, it’s rarely the panel. It’s almost always what’s under it.
Which Oldcastle Models This Applies To
Oldcastle makes two main fence lines you’ll see around Los Angeles backyards: the concrete post-and-panel system and the vinyl privacy line. The concrete line uses tongue-and-groove panels that slide into slotted posts, and the vinyl line uses hollow posts with routed channels that the panels lock into. They are not interchangeable, and that’s the first thing we check on site. Mixing a concrete panel into a vinyl post channel is a two-hour headache that ends with a cracked panel and a trip back to the supply yard.
If you still have the original paperwork, the series name is on the top right corner of the invoice. No paperwork? Flip a panel over and look for a molded code near the bottom edge. Oldcastle stamps a date wheel and series code into both concrete and vinyl panels. The stamp is faint on older installs, so we bring a flashlight and a wire brush. For aftermarket parts, we only use suppliers who match Oldcastle’s channel depth and post inner dimensions exactly. A generic panel that’s an eighth-inch too thick will bind in the channel the first hot afternoon when everything expands. In Los Angeles, that’s most afternoons.

Signs Your Oldcastle Fence Installation Is Failing
- Post lean without soil movement. If the post is tipping but the ground around it is flat, the concrete footing was poured too shallow or the post base is rusting out. In Los Angeles clay soil, a footing less than 24 inches deep heaves and settles within two or three wet winters.
- Gate drags on the latch side. The most common cause on Oldcastle systems is the hinge post working loose from its footing, not a hinge failure. The gate gets heavier to swing, the latch stops lining up, and eventually the post cracks the panel beside it.
- Cracks running vertically through the post, not the panel. Concrete Oldcastle posts crack when water gets into the post cap seam, sits there, and the freeze-thaw cycle does its work. Los Angeles doesn’t hard-freeze often, but the San Fernando Valley drops below 32 enough nights each January to matter.
- Panels chattering or rattling in the channel when the wind hits. That means the panel-to-channel fit has worn loose, usually from repeated thermal expansion. It starts as noise, then the panel starts walking out of the slot. We’ve seen a whole 30-foot run fall in one gust because nobody tightened the end posts.
- White crust or rust streaking down the post face. On concrete posts, that’s efflorescence from standing water inside the footing. On vinyl, rust streaks usually mean the internal steel stiffener is corroding. Either way, the post is done and the repair needs to happen before the panel goes with it.

AfterReplacement Cost & What’s Included
In Los Angeles, replacing a failed section of Oldcastle fence typically runs $4,130 to $10,620 depending on how many posts have to come out and whether the panels can be salvaged. A single-post replacement with panel reset usually lands near the bottom of that range. A full run replacement with new concrete footings, new panels, and a new gate frame pushes toward the top.
Every quote includes removal and haul-off of the failed section, new or salvaged materials, concrete footing work at the depth Los Angeles soil actually requires, and leveling so the top rail runs true. You get the line-item price in writing before we dig the first hole. The work is covered by our 365-Day Done Right Promise, which means if the new post shifts or the gate gets sloppy within a year of completion, we come back and fix it at no charge. No dispute process, no conditions.
| Scope of Work | Typical Los Angeles Price Range |
|---|---|
| Single post replacement, panel reset | $4,130 – $5,310 |
| Gate hinge post replacement + hardware | $4,720 – $6,490 |
| Section replacement (3 – 5 posts, panels reused) | $5,900 – $8,260 |
| Full run replacement with new panels and gate | $8,260 – $10,620 |
DIY or Call Us?
You can safely check the gate alignment, look for cracks at the post bases, and snap a photo of the stamped series code under the panel. That’s useful, and it helps us bring the right part on the first visit. What you shouldn’t do is pull a post out of its footing yourself. A concrete Oldcastle post with the panel still in the channel is heavy, and when it lets go, it lets go fast. We’ve reset fences where a homeowner tried to brace a leaning post with a 2×4 and ended up with the whole section leaning on a neighbor’s car.
If the post is rusted at the base or the footing has cracked loose, that’s a two-person job with a post puller and a fresh concrete pour. We handle it in a day most times. Call (803) 680-2547 and we’ll get you a written estimate before any work starts.
FAQs
A properly set Oldcastle concrete post in Los Angeles clay will last 20 to 30 years, while the panels can go 30-plus if the posts stay square. Vinyl post systems tend to fail earlier, usually at the internal steel stiffener, which rusts in our coastal air and is harder to replace than the post itself.
Call (803) 680-2547 and we’ll assess what’s failing and what’s got years left in it.
No. A cracked concrete post is a structural failure, not a cosmetic one. You can patch the surface with a masonry repair product, but the post will keep moving and the panel above it will eventually crack. Replacement is the honest fix, and it’s usually the cheaper fix over three years. Call (803) 680-2547 for a straight answer on your specific fence.
A single post replacement with panel reset takes about half a day, including concrete curing time under normal Los Angeles conditions. A full run replacement with a new gate is a one-to-two-day job. You’ll know the schedule before we start, and the written price doesn’t move once the work begins.
We carry the common Oldcastle slotted posts, matching panels, post caps, and gate hardware on our trucks for Los Angeles service calls. If you have a less common series, we’ll match the stamped code and have the exact part before your install date. Call (803) 680-2547 and we’ll confirm we have your part on hand before you schedule.
