Wrought Iron Railings in San Jose, Built From Your Measurements
We design, fabricate and install wrought iron railings in San Jose for front porches, entry steps, second-story balconies, Juliet balconies and interior stairs. We measure your site, draw the rail to scale, then cut and weld it in our shop so every post lands where your concrete or framing can hold it.
A quick word on names. Most railings sold as wrought iron today are ornamental mild carbon steel, which welds cleanly and costs far less than true forged iron. We use mild steel for pickets, rails and posts, and we add hand-forged scrolls, leaves and collars when a design calls for real blacksmith work. Your quote spells out which is which.
San Jose has plenty of iron worth replacing. Census data shows 60% of the city's housing was built before 1980. Check a range on our railing cost calculator, then call (408) 409-8723 for a free on-site estimate.
What an Iron Railing Job Includes
- A free visit to measure every run, photograph the mounting surfaces and talk through style and color.
- Scaled shop drawings showing rail height, picket spacing, post locations and any decorative panels.
- Drawings and finish samples for a permit or HOA submittal when your project needs one.
- Cutting, bending and welding in our shop, with welded picket joints instead of screwed brackets.
- Surface prep, zinc primer or hot-dip galvanizing, then oven-cured powder coat.
- Installation, post anchoring, sealed post bases and haul-away of the old railing.
When an Old Iron or Wood Railing Has Run Its Course
The median San Jose home was built in 1976, so a lot of railings here are pushing fifty. These are the signs we look for on a first visit:
- Rust at the post base. Orange staining or bubbling where steel meets concrete means water has been sitting in the post pocket. The steel thins there first, out of sight.
- A rail that moves. If the top rail shifts when you lean on it, an anchor or weld has let go. A residential guard has to resist a 200-pound load at the top.
- A short rail. Many older homes have 36-inch guards built under earlier rules. Current California code calls for 42 inches where the drop is more than 30 inches.
- Wide gaps. If a 4-inch ball slips between the pickets, a small child can too.
Not sure whether yours can be saved? Our railing repair service fixes sound rails with failed welds or rusted posts, and our post on warning signs a railing needs repair walks through what to check yourself.
Iron Styles, Materials and Finishes
| Option | Look | Where it fits | Installed price |
|---|---|---|---|
| Square pickets, flat top rail | Clean and traditional | Ranch porches, entry steps | $65–$95 per ft |
| Twisted or basket pickets, collars, scroll accents | Classic ornamental | Spanish and Mediterranean entries, balconies | $95–$135 per ft |
| Forged scrolls and custom ornamental panels | One of a kind | Restorations, statement stairs | $300–$900 per ft |
The finish decides how long iron lasts. Brushed-on paint over bare steel is the cheapest option and the first to fail. Our standard is surface prep, a zinc primer, then electrostatic powder coat cured in an oven. For homes near the Alviso and Sunnyvale baylands, where the air is damp and salt-tinged, and for posts set in lawns or planters, we recommend hot-dip galvanizing under the powder coat.
Satin black is the usual pick; bronze and dark gray hide dust better, and lighter colors stay cooler on sunny steps.

Code Numbers Every Iron Drawing Must Pass
California requires a guard wherever a walking surface sits more than 30 inches above the grade below (measured within 36 inches horizontally), and that guard must be 42 inches tall. No opening may pass a 4-inch sphere, except the triangle beside a stair tread, where the limit is 6 inches. The top must resist a 200-pound concentrated load, infill must take 50 pounds on one square foot, and stair handrails sit 34–38 inches above the tread nosing.
Decorative ironwork gets no pass. A scroll that opens wider than 4 inches fails the same as a missing picket, so we lay out every panel against the sphere rule before the shop bends a bar. Replacing more than about half of an existing guard is commonly treated as a replacement that must meet current code, so a 36-inch porch rail usually comes back at 42. Our California railing code guide covers the rules in plain English. Whether you need a permit depends on height, attachment and scope; our San Jose railing permit guide explains it, and we confirm with San José's Permit Center before fabrication. Many HOAs also require architectural review, and we prepare those drawings and finish samples too.
How Your Iron Railing Gets Made
Measure on Site
We measure each run, check what the posts will anchor into, and talk style.
Draw to Scale
You get CAD shop drawings showing heights, picket spacing and every decorative piece.
Check Code and Permits
Heights, gaps and loads are verified, and permit or HOA sets go out when needed.
Cut and Weld
Pickets, rails and posts are cut, bent and welded in our shop.
Prime and Powder Coat
Steel is cleaned, zinc-primed or galvanized, then powder coated and oven-cured.
Install and Inspect
We anchor the posts, seal the bases and walk the finished rail with you, sphere gauge in hand.
Iron in the South Bay: Heat, Bay Air and Moving Ground
Valley weather is easy on people and hard on cheap finishes. NOAA's 1991–2020 normals put the July average high at 80.8°F at San José airport and 82.2°F in central San Jose, and about 91% of the year's rain falls between November and April. Months of sun, a wet winter and daily sprinkler spray on the post base make paint chalk, crack and let water reach the steel.
The ground matters too. The Hayward fault zone reaches southeast into the Evergreen area of east San Jose and the Calaveras fault bounds the east side of the valley. The 1989 Loma Prieta earthquake (M6.9) caused heavy damage in Los Gatos. There is no separate seismic railing code, but we build as if it matters: posts are core-drilled and grouted into sound concrete or through-bolted to framing, and connections are welded, not screwed.
San José adopted the 2025 Fire Hazard Severity Zone maps in June 2025, and parts of the east and south foothills are mapped High or Very High. Steel does not burn the way a wood rail can.
What Wrought Iron Costs in San Jose
Standard ornamental iron runs about $65–$135 per linear foot installed in 2026, and true hand-forged work runs $300–$900 per foot. Most residential iron projects land between roughly $700 and $6,000. What moves your number:
- Total length, plus corners and turns, which add roughly 20–30%.
- Stair runs, which cost more than level runs.
- Picket style and the amount of forged detail.
- Mounting: core drilling into concrete, fascia mounting, or repairs to soft framing.
- Permit fees of roughly $50–$500, plus hillside access and HOA-specified finishes.

Why San Jose Homeowners Choose Us for Iron
Every Panel Checked Before Steel Is Cut
Each drawing is checked against the 42-inch guard height, the 4-inch sphere rule and the 200-pound top-rail load before fabrication starts. Scrollwork gets the same scrutiny as plain pickets, because ornate panels are where gaps quietly grow past 4 inches. You sign off on the drawing, and the shop builds exactly what you approved, so there is no field cutting to fix spacing and no surprise at inspection.
A Layered Finish, Not a Spray Can
Steel is prepped, zinc-primed or hot-dip galvanized, then electrostatically powder coated and cured in an oven. That system matters in a valley that sees essentially no rain from June through September and then a wet winter: summer heat bakes cheap paint, and the first storms push water into every crack. For baylands homes and posts set in soil, we default to galvanizing under the powder coat.
One Shop for Every Material
Iron is not always the right answer, and we will say so when it isn't. Because we build iron, aluminum, stainless cable and glass railings, we can put a classic iron rail on your front porch and a cable rail on the back deck, matched in color and post style. You deal with one crew and one schedule, and you can reach us at (408) 409-8723 from first measure to final walkthrough.
Iron Railings Across Santa Clara County
We build iron railings for homes in San Jose, Campbell, Los Gatos, Saratoga, Santa Clara and Milpitas. About 69% of Campbell's housing predates 1980, so porch rail replacement is steady work there. In Los Gatos, the Town's Residential Design Guidelines say porch railings should generally be wood unless the home's architectural style allows metal or stone, so we show how iron suits your style before you apply.
Pair Your Railing With Matching Ironwork
Carry the same pickets to the driveway with custom iron gates, bring iron indoors with interior stair railings, or compare a rust-free option in powder-coated aluminum railings. Curious who you would be hiring? Read about our shop and process, or request a free wrought iron estimate online.
FAQ
Questions, Answered
Straight answers on cost, code, permits and materials. Still unsure? Call and ask.
Is your wrought iron real wrought iron?
Most modern wrought iron railings, ours included, are made from ornamental mild carbon steel. It is strong, welds cleanly and takes powder coat well. When a design calls for blacksmith work, we add hand-forged scrolls, collars and leaves, or build fully forged panels, which run about $300–$900 per foot installed. Your quote lists exactly which parts are forged.
Will an iron railing rust in San Jose?
Bare or painted steel will rust eventually, usually at the post base first. Powder coat over zinc primer, or over hot-dip galvanizing near the baylands, holds up far longer. Rinse the rail a couple of times a year, keep sprinklers off the posts, and touch up any chip that reaches bare metal right away.
Can you match the ironwork already on my house?
Usually, yes. We photograph and measure the existing gate, window grilles or railing, then match picket size, spacing, collars and scroll shapes in the shop drawing. Powder coat colors can be matched closely to existing finishes. Very old hand-forged pieces may need custom forging to match exactly.
Do I need a permit to replace an iron railing in San Jose?
It depends on the height of the walking surface, what the railing attaches to and how much of the guard you are replacing. New balcony guards and work tied to structural repairs usually need a permit. We check your address with San José's Permit Center and prepare the drawings if one is required.
My porch railing is only 36 inches tall. Does it have to be raised?
Not automatically. Many older homes have 36-inch guards built under earlier rules. Once you replace more than about half of the guard, though, it is commonly treated as new work that must meet today's 42-inch requirement. Confirm with the building division; we design replacements to 42 inches by default.
