Aluminum fence installation in St. Louis offers homeowners a rust-resistant, low-maintenance perimeter that works on sloped ground and keeps views open. Unlike wood or vinyl, ornamental aluminum and wrought iron fencing holds up to moisture without rotting or warping, and in St. Louis historic districts and master-planned communities, it is often the only material architectural review boards will approve. We install powder-coated aluminum and ornamental iron for front yards, pools, and estate boundaries across the Greater St. Louis area, with crews who understand how to rack fence over rolling terrain and set posts to last. Since 2011, we have worked with homeowners in St. Louis, Kirkwood, Chesterfield, Ballwin, and surrounding communities to build fences that close a lot without closing the view. Whether you need a formal perimeter in Clayton, a pool barrier in Webster Groves, or a heritage-compliant fence in a protected neighborhood, aluminum and ornamental iron deliver both durability and design.
Why Aluminum and Ornamental Iron Fencing Matters in St. Louis
St. Louis homes sit on varied terrain, from level suburban lots to properties that slope noticeably toward drainage. Wood fences settle and rot at the post line where moisture collects; vinyl can crack in temperature swings and sag under wind load. Aluminum and ornamental iron do neither. A powder-coated aluminum fence rated to resist corrosion will not rust, splinter, or require staining year after year. Ornamental iron, when properly finished, delivers the formal aesthetic that historic review boards in St. Louis and Clayton demand, and it handles racked installation (where the fence line follows ground slope) without the structural compromise that wood and vinyl face.
- Aluminum resists rust and rot, eliminating the maintenance cycle that wood fencing demands.
- Both materials rack cleanly over sloped ground without stepping, preserving sightlines and curb appeal.
- Powder-coated finishes hold color and gloss for decades with only occasional washing.
- Ornamental iron and aluminum meet historic district design guidelines where wood and vinyl do not.
- Pool barrier installations in aluminum meet local code requirements without the durability concerns of other materials.
Choosing the right material for your lot depends on terrain, sight lines, and local approval requirements. We assess all three before recommending an install approach.
Key info: St. Louis historic districts and many HOAs in Kirkwood, Clayton, and Chesterfield restrict fence materials by covenant. Aluminum and ornamental iron are almost always permitted where wood and vinyl are not. Verify your deed restrictions and HOA rules before ordering materials, or call us at (314) 668-1539 and we will help you confirm what your community allows.

How We Install Aluminum and Ornamental Iron Fencing in St. Louis
Every aluminum and ornamental iron fence begins with a site walk. We identify the fence line you want, check for utilities using Missouri 811 locates (required by law before digging), and measure grade changes. On sloped lots, we determine whether the fence will be racked (following the slope in one plane) or stepped (dropping in increments). Racked fence looks cleaner and is stronger; stepped fence works where the slope is very steep or where the aesthetic demands it. Posts are set in concrete at 5 or 6 foot spacing, depending on wind exposure and panel height. Rails are welded or bolted, and the finish is inspected before we leave the site.
- We call 811 to locate utilities, and we dig only after the locate marks are in place and verified.
- We measure the site and determine whether racking or stepping best fits the grade and your design intent.
- Posts are set in concrete to frost depth, tamped solid, and braced until the concrete cures.
- Rails are attached with bolts or welding, depending on the material and your preference for future removal or repair.
- The finished fence is inspected for plumb, alignment, and finish quality before final sign-off.
A typical residential run of 100 linear feet takes two to three days, depending on terrain and whether we are racking or stepping. More complex jobs, like those involving gates or ornamental iron scrollwork, take longer.
Local example: A homeowner in Ballwin with a sloped front yard needed a fence that would not block the view of the street but would contain a pool area. We installed a 4-foot racked aluminum fence with open pickets, which follows the grade smoothly and meets the sight-line requirements of the HOA. The same approach works in Chesterfield, where many estates require formal perimeter fencing that does not obstruct the landscape.

Installation Methods and Material Finishes
| Approach | Description | Best for |
|---|---|---|
| Powder-coated Aluminum | Lightweight, corrosion-resistant extrusion finished in UV-stable powder coat, available in white, black, bronze, and custom colors. | Residential front yards, pools, and properties where low maintenance and long finish life are priorities. |
| Wrought Iron (Ornamental) | Forged and welded steel with pickets, scrolls, and finials, finished in powder coat or traditional paint; requires touch-up on scratches to prevent rust. | Historic districts, estates, formal perimeters, and HOAs that specify ornamental design and heritage aesthetics. |
| Racked Installation | Fence line follows ground slope continuously, with posts set plumb and rails angled to maintain parallel lines at grade. | Sloped lots, where stepping would interrupt sight lines or where continuous aesthetic is required by design or code. |
| Stepped Installation | Fence descends in level increments, with posts dropping at intervals; each section remains level and plumb. | Very steep slopes or where horizontal sight lines must be maintained at each step for safety or design intent. |
Aluminum and Ornamental Iron Fencing Cost in St. Louis: What to Expect
Aluminum fence installation in St. Louis starts at approximately $42 per linear foot, depending on height, finish, and site conditions. A typical 4-foot residential run with powder-coated aluminum and standard post spacing will fall in that range. Ornamental iron and custom finishes cost more, typically $55 to $85 per linear foot, because each piece is often fabricated to order and the material is heavier. What moves the price up or down is terrain, access for equipment, whether you are racking or stepping, and the complexity of any gates or custom details.
Posts set in concrete on a sloped lot cost more than posts on level ground because we have to account for racking geometry and may need to set posts deeper for stability. If your property requires a Missouri 811 utility locate or if we find buried obstacles during digging, that adds time. Gates, self-closing hardware, and ornamental scrollwork are line-item additions.
The best way to know what your fence will cost is to get two or three on-site estimates. We offer free estimates with a response within 24 hours. Call us at (314) 668-1539, describe your property and what you want, and we will schedule a walk-through. See our full pricing guide for more detail on what drives cost in different scenarios.
Aluminum and Ornamental Iron Fencing Near Me: What St. Louis Homeowners Should Know Before You Hire
Aluminum and ornamental iron fencing is a permanent investment, and choosing the right installer matters. We are fully insured and an AFA Member Installer (American Fence Association), which means we follow industry standards for post depth, material gauge, and installation technique. Before you sign a contract with any fencing company, verify that they pull permits where required by your city or county, understand HOA and historic district rules, and can show you examples of work in your neighborhood or on similar terrain.
Get your property surveyed or confirm the fence line in writing with your neighbor before we set the first post. We work from the line you identify, but we do not determine property boundaries. If your fence crosses or sits near a utility easement, the 811 locate protects both of us. Ask any contractor you consider whether they handle their own install or subcontract it out; we do our own work with the same crews every time, which means consistency and accountability.
Check references, especially from homeowners with similar terrain or HOA situations. Ask about warranty on the finish and on the install workmanship. Understand what happens if a post settles or a rail needs repair down the road. We repair fences before we recommend replacement, so ask whether a contractor will do the same.
