Techo-Bloc Fence Installation: The San Francisco Owner’s Guide
Techo-Bloc fence installation in San Francisco typically runs $4,130 to $10,620 for a complete post-and-panel run, depending on linear footage, post depth, and whether we’re pulling permits for a new fence line or replacing existing footings. Most replacement jobs take one to two days on site once materials are staged. You’ll know a Techo-Bloc fence is failing the same way every owner finds out: a post starts leaning after a winter storm, a panel rocks loose at the base, or you notice hairline cracking where the post meets the footing from years of wet-dry cycles in ocean air.
We are an independent contractor, not a Techo-Bloc dealer or affiliate. But we install their fence systems regularly, and we know what holds up in San Francisco’s specific conditions. Curtis Lane runs point on fence jobs, and he’s the one who’ll tell you straight whether a repair makes sense or a full replacement is cheaper in the long run.
Which Techo-Bloc Models This Applies To
Techo-Bloc’s fence product lines split into two camps: the Rafale series, which uses modular concrete posts with wood or composite panels, and the Industria line, which is all-concrete post-and-panel construction meant for property lines and sound dampening. The compatibility gotcha most San Francisco homeowners hit is this: Rafale posts have a routed channel sized for specific panel thicknesses. If you bought the house with a Techo-Bloc fence already installed and a panel rotted out, you can’t just drop in a pressure-treated 2×4 fence board from a lumberyard. The channel spec doesn’t match, and you’ll end up with a panel that rattles in the wind or won’t seat flush at the post cap.
For identifying what you have, look at the post cap. Rafale caps are rounded and stamped with the Techo-Bloc name on the underside. Industria caps are flat, wider than the post face, and set with four torx screws. Take a photo of that cap and a tape measure across the panel width, and we can usually confirm the series before we come out.
On OEM versus aftermarket: Techo-Bloc’s own panels and connectors are cast to their manufacturing tolerances, and in a city with as much ground movement as San Francisco, those tolerances matter. Aftermarket post brackets and panel clips exist, but we’ve pulled too many of them off fences in the Sunset and Ingleside where the powder coating was already failing within two seasons. For post-and-panel structural pieces, we recommend sticking with Techo-Bloc parts. For fasteners and concrete footings, we use commercial-grade equivalents that exceed what the factory ships.
Styles & brands we work with
Signs Your Techo-Bloc Fence Installation Is Failing
- Post lean after rain. A Techo-Bloc post that tilts more than an inch out of plumb usually means the footing was poured too shallow or the base material washed out. In San Francisco’s heavy clay soils, water pushes sideways against a buried post every winter. The post itself rarely fails; the footing does.
- Panel rocking at the base channel. When a Rafale or Industria panel moves side to side at the bottom but not the top, the connecting clip or channel spacer has cracked. This is the most common failure we see after a few seasons of wind coming off the ocean in the Richmond and Outer Sunset neighborhoods.
- Cracking where post meets footing. Hairline cracks at the post base are normal after five to seven years, but if the crack widens to a quarter inch or you see spalling chips falling away, moisture has gotten into the post core. Once that begins, the post will not improve on its own.
- Fence gate binds or won’t latch. Techo-Bloc gate posts carry four times the lateral load of a line post. A gate that starts dragging on the latch side is telling you the gate post footing has shifted. Adjusting the hinges buys you time but doesn’t fix the cause.
- White chalky residue on post faces. This is efflorescence, not structural failure, but it means water is moving through the concrete. It’s cosmetic on its own, though it often signals a drainage problem at the base that will eventually undermine the footing.

AfterReplacement Cost & What’s Included
For a typical San Francisco yard, figure between $4,130 and $10,620 for a complete Techo-Bloc fence replacement. The spread comes down to four things: linear footage, whether the existing footings are sound enough to reuse, access to the work site, and whether we’re replacing panels only or pulling posts and repouring footings.
Here’s the breakdown of what you’re paying for:
- Post replacement with new concrete footing: $220 to $420 per post, including excavation, gravel base, and concrete. Techo-Bloc posts run roughly $180 to $340 each depending on height and series.
- Panel replacement: $85 to $185 per linear foot for Rafale or Industria panels, including connectors and post cap re-seating.
- Full removal of old fence and debris haul: $700 to $1,400 depending on length and access. San Francisco debris disposal rates push this higher than most cities.
- Permit and inspection: $400 to $900 when required. San Francisco requires a permit for any fence over six feet or any fence in a front setback, and we pull the permit ourselves, so that number is already accounted for in our written quote.
Every quote includes a written line-item breakdown before work starts. No numbers move at the door. The 365-Day Done Right Promise covers the full installation: if a post shifts, a panel cracks at the connection, or a gate binds inside one year from job close, we come back and fix it at no charge.
DIY or Call Us?
There are things you can safely check on your own: whether a panel is simply unseated from its channel, whether a hinge screw has backed out, whether leaves have packed in against the post base and trapped water. Those are maintenance items, and a homeowner with a cordless drill can handle them.
What you should not attempt is pulling and resetting a Techo-Bloc post. A six-foot concrete post with a wet footing weighs over 250 pounds. When it goes over, it goes fast. And a post that’s been pulled needs its footing excavated to the frost line, backfilled with gravel, and repoured with concrete mixed for San Francisco’s soil conditions. Get that wrong and you’re redoing the job in two winters. That’s where it’s worth a call. We’ll come out, confirm which series you have, and give you a written price.

FAQs
A properly installed Techo-Bloc fence with adequate footings will last 25 to 40 years in San Francisco’s climate. The concrete components themselves are extremely durable, though panel connectors and fasteners typically need replacement every 8 to 12 years due to salt air corrosion, especially within half a mile of the ocean in neighborhoods like the Outer Sunset or the Richmond. Call (831) 610-5598 if you want us to look at your specific fence line.
A leaning post can sometimes be stabilized by recompacting the base material and injecting expansion grout into the existing footing, but if the footing has cracked through or the post has rotated more than five degrees, a post replacement is the only repair that will hold. We’ll tell you which condition you have before you spend a dollar.
Most residential Techo-Bloc fence replacements in San Francisco take one to two days on site after materials are delivered. Permitting can add one to three weeks on top of that, depending on the San Francisco Department of Building Inspection queue.
We stock the connectors, post caps, and fasteners most commonly needed for Techo-Bloc fence repairs, and we order series-specific posts and panels direct for each job. If your fence is Rafale or Industria, we can usually confirm part availability within one business day of seeing photos and measurements.
We also install and maintain related home systems, including KraftMaid cabinetry, Cambria surfaces, and Silestone countertops, so if your fence project turns out to be part of a larger exterior upgrade, we can scope the whole thing in one written quote.
