CGI Fence Installation: The Austin Owner’s Guide
CGI fence installation in Austin typically runs $3,500 – $9,000 for a complete section replacement, depending on post condition, linear footage, and whether we’re pulling new tension wire or reusing existing hardware. We stock common CGI-compatible posts, brackets, and tension components on our trucks, and most repair visits get the fence standing and secure in a single day. You usually find out your CGI fence needs attention the hard way: a post leans hard after a storm, a panel rattles loose at the base, or the top rail separates where two sections meet.
CGI here means corrugated galvanized iron, the wavy steel paneling you see on older Austin properties, garden fences, and a fair number of South Congress bungalows. It’s tough material, but the installation hardware around it ages faster than the panel itself.
Which CGI Models This Applies To
CGI fencing isn’t sold in tidy model lines like cabinets or countertops. It’s manufactured in panel profiles, and the two you’ll run into around Austin are the classic 3-inch corrugation pitch and the deeper 5-inch profile used on some commercial and agricultural runs. The panel gauge matters more than anything: older Austin fences lean toward 26-gauge or 28-gauge galvanized sheet, while newer installations often use 29-gauge with a lighter zinc coating. Both hold up fine against cedar and limestone dust, but the 29-gauge panels dent easier when a mower or a teenager throws something at them.
Here’s the compatibility gotcha we see on service calls: the corrugation profile on the panel has to match the slot spacing on the bottom channel and the notched top rail, or the panel sits cocked and rattles in the wind. You can’t mix a 5-inch profile panel into a frame cut for 3-inch corrugation and expect it to seat. If the original installer ordered from a metal supplier like Mueller or Westbrook Metals, there’s a good chance we can match the profile from those same supply houses. Penhallow Remodeling is an independent contractor, not affiliated with CGI, which means we’re free to source the exact profile that fits your existing frame rather than forcing a proprietary match.
On the OEM-versus-aftermarket question: for galvanized panels, the aftermarket product from a Texas metal supplier is often indistinguishable from what the fence company branded as OEM, because most CGI paneling comes off the same regional mills. What we won’t substitute is the structural hardware. Cheap import brackets rust through in three Austin summers. We use galvanized or powder-coated steel brackets rated for outdoor exposure and high wind load.

Signs Your CGI Fence Installation Is Failing
- Post lean at the gate hinge. The gate post carries the most repeated load on any fence, and in Austin’s clay soil it’s usually the first to move. You’ll see the gate start to drag at the latch side. The post is losing its footing or the concrete collar around it has cracked.
- Panels rattling in the wind. That metallic chatter when a gust comes down the street means the panel is no longer seated tight in the bottom U-channel. The channel may be packed with dirt, or the fasteners holding it to the post have worked loose.
- Rust bleeding from fastener holes. This is the classic CGI failure in a humid climate. Water sits in the corrugation valleys, the zinc coating wears at the screw points, and rust starts streaking down from every penetration. The panel is still sound, but the attachment points are failing.
- Top rail separation at the seam. Where two panels meet, the top rail can pull away if the rail was butt-cut too short or the splice bracket corroded. You’ll see a visible gap and the panel will flex when you push on it.
- Ground line rot on wooden posts. A lot of older Austin CGI fences were built on 4×4 cedar or pressure-treated posts. After a decade in Central Texas soil, the post rots right at grade and the whole section leans as a unit. The panels are fine; the posts are gone.

AfterReplacement Cost & What’s Included
For a typical Austin residential CGI fence repair or section replacement, you’re looking at $3,500 – $9,000 installed. On the lower end, we’re replacing a single panel section, swapping out failed fasteners, and resetting one post. The upper end covers a longer run: multiple posts replaced, new bottom channels, fresh tension wire, and panels matched to your existing corrugation profile.
What moves the number the most:
- Post condition. If we’re digging and setting new steel posts in concrete, that’s labor and materials you can’t skip. Reusing sound posts keeps the job under $5,000 on most residential runs.
- Linear footage. Material costs scale directly. A 40-foot run and a 120-foot run are different jobs.
- Access. Fences built tight against a property line with no room to work on the neighbor’s side take longer and cost more.
- Profile matching. Standard 3-inch pitch panels are readily available. The deeper 5-inch profile sometimes requires a custom order from the supplier, which adds material cost and a few days of lead time.
Every quote includes parts, labor, haul-away of the failed material, and our written 365-Day Done Right Promise. If the repair fails inside a year, we come back and make it right at no charge. That’s in writing on every job.
DIY or Call Us?
You can safely inspect a CGI fence yourself. Walk the line, push gently on each panel, and look for the symptoms I listed up top. You can also clear dirt and leaves out of the bottom U-channels with a screwdriver and a hose. That’s honest maintenance, and it’ll extend the life of any galvanized fence in Austin’s clay-heavy soil.
What I wouldn’t DIY is pulling a leaning post or re-tensioning wire under load. A steel post that’s moved in the ground is under lateral pressure, and if you dig the collar out wrong it can spring back at you. Tension wire that’s snapped or pulled tight can whip when released. None of this is worth a hand injury or a trip to urgent care. If the panel is loose, the post is leaning, or the hardware has rusted through, call us at (325) 225-5429. Trevor Nash will walk the fence with you, point out exactly what failed and why, and put a written number in your hand before any work starts.
FAQs
A well-installed CGI fence on galvanized steel posts will last 20 – 30 years in Austin before the panels need replacement, though the hardware and fasteners usually need attention around the 10 – 15 year mark. Cedar posts cut that lifespan roughly in half, because the post fails at ground level long before the panel does.
In our experience, about 70% of failing CGI fences in Austin can be repaired by replacing posts, channels, and fasteners while keeping the original panels. The exception is panels with heavy rust-through or structural creases, which we’ll replace and match to your existing corrugation profile. Call (325) 225-5429 and we’ll tell you which side of that line your fence sits on.
Most single-section repairs are done in one day, including post setting if we’re using fast-cure concrete. A full 100-foot run with multiple new posts usually takes two to three days, with an extra few days of lead time if your panel profile requires a custom order from the supplier.
We stock common 3-inch corrugation galvanized panels, U-channels, post brackets, and tension wire on our service trucks. The deeper 5-inch profile and heavier gauge panels are usually a same-week supplier order here in Austin, and we’ll tell you the lead time before any money changes hands. Call (325) 225-5429 for a free estimate.
