Unilock Fence Installation: The San Diego Owner’s Guide
Unilock fence installation in San Diego typically runs $4,130 – $10,620 for a full perimeter fence using Unilock-compatible posts, panels, and caps, with most jobs completed in two to five days. If your Unilock fence section has cracked, shifted, or pulled loose from its post base, we stock the installation hardware and replacement components to match what you already have. Most homeowners discover a problem the same way: a panel starts leaning after a wet winter, or a post cap pops off and reveals the corrosion underneath.
The short version: if your Unilock fence is failing at the connection points rather than the panel surface itself, this is usually a parts-and-installation fix, not a full fence replacement. Call us at (619) 604-9624 and we’ll figure out which components you need before we ever touch a post hole.
Which Unilock Models This Applies To
Unilock fence installation covers the brand’s modular concrete fence wall systems rather than traditional wood or vinyl fencing. The most common lines we work with around San Diego are the Estate Wall, Brussels Dimensional, and the Unilock fence post-and-panel combinations built from the same paver-grade concrete as their patio stones. These systems use a tongue-and-groove panel design that slides into channeled posts, which means the failure point is almost never the panel itself. It’s the post base, the cap adhesive, or the aggregate fill that gives out first.
Before you order anything, flip over a loose post cap or check the back face of an end panel. Unilock stamps most of their structural components with a series code near the bottom edge, usually two letters followed by four digits. If the stamp has worn off, measure the post channel width with a tape measure. Unilock posts come in standard channel widths that differ by series, and a sixteenth of an inch matters when you’re sliding panels in. We’ve seen aftermarket posts that look identical but run a hair narrow, which means the panel binds halfway down and someone has to grind the channel wider on site. That’s an extra hour you shouldn’t have to pay for. For Unilock specifically, we order OEM posts and caps when they’re still in production for the series. For older discontinued lines, we source a matched aftermarket equivalent and confirm the channel dimensions before it ever goes on the truck.
One compatibility note worth knowing: Unilock’s older fence caps were made with a slightly different aggregate mix than current production, so a new cap on an old post can show a subtle color shift in direct sun. San Diego’s UV exposure makes that shift show up faster than it does in, say, Seattle. If that bothers you, we can seal the whole fence line after installation so it weathers as one unit instead of piecemeal.
Styles & brands we work with
Signs Your Unilock Fence Installation Is Failing
- Panels tilted or leaning at the post. This usually means the post base has shifted because the original installers didn’t dig below San Diego’s shrink-swell clay line or didn’t compact the base properly. The post is moving, not the panel.
- Cracks running vertically through post caps. Water gets into the cap’s channel, sits there, and expands during a cold snap or a rare overnight freeze in the inland valleys. Once a cap cracks, it lets more water in, and the cycle accelerates.
- White, chalky residue creeping up from the bottom edge of panels. That’s efflorescence, and it tells you water is wicking up through the panel from a saturated base. In coastal San Diego neighborhoods like Point Loma or Ocean Beach, salt air makes this worse.
- Rattling or shifting panels when you push on them by hand. The aggregate fill inside the posts has settled or eroded. A settled post loses its grip on the panel edge, and eventually the panel can walk itself out of the channel.
- Post caps that lift off with almost no effort. The original adhesive has failed. This is the cheapest fix on the list, but ignoring it lets water into the post cavity, and then you’re looking at the crack problem above.

AfterReplacement Cost & What’s Included
In San Diego, a partial Unilock fence repair – say, replacing one post, one panel, and two caps – runs between $950 and $2,100 depending on post depth and how much of the old base needs to be excavated. A full fence installation using Unilock components ranges from $4,130 to $10,620. The three things that move your number: linear footage, post depth, and whether the existing base material is clean or full of buried concrete from an old fence line.
We give you a written price before any work starts. That price includes the parts, the labor, the base material, and the haul-off of whatever we pull out. If we open the base and find the soil condition is worse than we estimated, we stop and show you what we found before we spend another dollar of your money. No change orders that show up after the fact. The installation itself is covered by our 365-Day Done Right Promise, which means if the fence shifts, cracks at a connection, or settles inside the first year, we come back and fix it at no charge. Not a service call fee, not a re-inspection fee. Just the fix.
DIY or Call Us?
There’s a spectrum here. Re-seating a loose post cap with fresh construction adhesive is a legitimate weekend job if you can scrape the old adhesive off clean. Checking a panel for movement and photographing the post base is also something any homeowner can do before calling us – it genuinely helps us price the job over the phone.
The part you shouldn’t do yourself is anything involving post excavation. Unilock posts on a fence line are heavy, often 60 to 90 pounds each for the larger series, and they’re set in a base that may be partially undermined. Pulling one out without knowing what’s underneath is how you get a crushed toe or a cracked panel that wasn’t cracked before. We also see homeowners re-set posts at the same shallow depth the original installer used – usually because they didn’t know the local issue. In San Diego, the clay in areas like Clairemont and La Mesa expands and contracts enough that posts set under 18 inches will move within two or three wet seasons. We set deeper and backfill with a compacted base that doesn’t heave. If you’ve already got a post out and you’re not sure about the base, call us at (619) 604-9624 before you pour anything. We’ll tell you what depth and material actually work here, and we won’t charge you for that phone call.
FAQs
Unilock fence systems installed correctly in San Diego typically last 25 to 35 years, with the posts and panels outlasting the caps and the cap adhesive. The concrete itself is the durable part. What shortens the lifespan here is water intrusion at the cap-to-post seam and soil movement under shallow posts. If the caps are re-sealed every five to seven years and the posts were set below the shrink-swell line, there’s no reason the fence shouldn’t last as long as the house around it. Call (619) 604-9624 if you want us to look at your specific fence line and tell you honestly how much life is left in it.
Yes, in most cases a single post or panel can be swapped without tearing out the whole fence line, as long as the failure is localized to one or two sections. The exception is when a run of posts was set too shallow and the entire line is drifting, in which case repairing one section just means the next section fails six months later. We’ll tell you which situation you’re in before we quote the work. Estimates are free, so you’re never paying to find out.
A single-post or single-panel repair usually takes half a day to a full day, including base excavation, re-set, and cleanup. A full fence installation typically takes two to five days depending on linear footage and what we find under the old fence line. We give you a defined arrival window before the work starts, and we leave the job site clean enough that you’d never know we were there except for the new fence standing straight.
We stock Unilock-compatible installation hardware and the most common post and cap sizes for the Estate Wall and Brussels Dimensional series, and we order OEM or matched aftermarket components for anything we don’t carry. You don’t need to source parts yourself. When we quote the job, the parts are already in the number we hand you, along with everything else, so there’s no surprise supply order after the work starts. Call (619) 604-9624 and we’ll check the series compatibility over the phone.
