CGI Fence Installation: The West Covina Owner’s Guide
CGI fence installation in West Covina typically runs $3,500 to $9,000 for a standard residential yard, depending on linear footage, post condition, and gate count. We stock CGI-compatible posts, rails, pickets, and gate hardware on our trucks, so most jobs are done in a single day once we’ve measured. Most homeowners discover the problem two ways: a gate that suddenly drags or won’t latch after a wind storm, or a section of fence leaning hard after a rain, because the post footing gave out or the rail connection rusted through. You should know what you’re getting before we ever pick up a tool. CGI fencing, the corrugated galvanized iron panels common across older Southern California homes, fails in predictable ways here in West Covina, and we’ll walk you through exactly what you’re paying for.
Which CGI Models This Applies To
CGI panels come in a few distinct profiles, and the wrong match is the most common ordering mistake we see. The big split is between classic corrugated CGI (the wavy panels you see on older ranch homes and commercial lots near Eastland Center) and flat-pan or mini-corrugated CGI used on more recent privacy fencing. Panel gauges run from 22-gauge light residential up to 16-gauge commercial; West Covina wind loads make 20-gauge or thicker the realistic minimum. You’ll find identifying stamps on the panel face or the bottom rail, usually a series code and gauge number. If the panel is painted, check the top edge for a manufacturer code. OEM CGI panels are thicker at the mounting points and pre-drilled to match original rail spacing. Quality aftermarket equivalents are fine for most residential repairs, but the rail-to-picket fastening pattern must be measured before we order, because CGI racks and rails from different suppliers don’t always share hole spacing. Mason Remodeling Co West Covina is an independent service provider, so we’re free to match the best panel to your existing fence rather than pushing one brand.
Styles & brands we work with
Signs Your CGI Fence Installation Is Failing
- Gate dragging on the latch side. The hinge post has settled or the rail has pulled loose from the panel edge. CGI gates are heavy, and a leaning post means the concrete footing has cracked below grade, which a new hinge won’t fix.
- Panels rattling against the rails in wind. The nylon or rubber washers behind the picket screws have dried and split from San Gabriel Valley heat. Each loose panel flexes in the wind and work-hardens the metal around the screw hole until the hole ovalizes.
- Rust streaks below fasteners and at panel overlaps. Galvanized coating has worn through, usually because panels were cut on-site and the cut edge was never sealed. Here, coastal-adjacent moisture and sprinkler overspray accelerate it faster than you’d expect.
- Sharp or flaking panel edges at the bottom rail. Water wicks up from soil contact and starts the delamination you can feel as a rough, peeling edge. It spreads inward far faster than the visible damage suggests.
- Fence section leaning after rain. The post footing was poured shallow or the post itself was set directly in soil. In West Covina’s clay soils, wet winters shift the ground enough that a 18-inch footing simply lets go.

AfterReplacement Cost & What’s Included
For a typical 50 to 70 linear foot yard in West Covina, CGI fence installation with new panels, new rails where needed, and reset posts runs $3,500 to $9,000 installed. The biggest driver is post condition: reusing existing sound concrete footings saves real money, while digging and pouring new footings for every post adds $60 to $110 per post. You’ll get a written line-item price before any work starts, including panel gauge, post count, gate hardware, and haul-away of the old material. That’s the no-hassle upfront pricing we’ve done since 2004, and it’s never been an option for us, it’s just how we bid. Our work carries a 365-Day Done Right Promise, so if a post settles or a rail loosens within a year of completion, we come back and fix it at no cost. No change orders, no surprise invoices.
| Scope | Typical Installed Price in West Covina |
|---|---|
| 30 linear ft CGI panel replacement, existing posts sound | $3,500 – $4,800 |
| 60 linear ft full fence, new panels + reset posts | $5,000 – $7,500 |
| Driveway gate in CGI frame, new hardware | $900 – $2,200 (added to fence scope) |
| Full yard, 100+ linear ft, new footings throughout | $7,500 – $9,000+ |
DIY or Call Us?
There are a few checks you can do safely. Look for a stamp on the panel face to identify gauge and series. Measure the distance between fasteners on the rail. Check whether posts are set in concrete or driven into soil. Those three facts help us price the job before we send a crew. What you should not do is pull a leaning post or cut CGI panels yourself. Torn or cut corrugated iron edges are genuinely dangerous, sharper than most people expect, and the metal wants to spring once it’s under tension. Even moving a sheet without gloves can open a hand fast. We’ll measure, match, install, and haul off the old metal.

FAQs
A properly installed CGI fence with 20-gauge or thicker panels and sealed cut edges lasts 25 to 40 years in West Covina’s climate. The failure point is almost always the post footing or an unsealed cut edge, not the panel itself. Call (707) 760-7579 if you want us to assess what’s actually failing on yours.
Sometimes. If the posts are sound and the damage is limited to one or two panels, we can cut out the bad section and splice in matching panels. The deciding factor is whether the existing rail spacing matches current panel hole patterns. Call (707) 760-7579 and we’ll tell you straight which way it goes.
Most residential CGI fence replacements in West Covina are done in one day once the panels are measured and ordered. Gates add a few hours; full re-footing adds a day. We’ll give you a schedule in writing before work begins.
We keep the most common 22-gauge and 20-gauge corrugated panels, rails, fasteners, and gate hardware on our truck inventory. Odd gauges, flat-pan profiles, and custom gate frames are ordered to spec and typically take a few business days. We also stock parts for KraftMaid, Cambria, and Silestone lines, but CGI fencing is the focus of this page.
