Why Ironworks Gate Co. Is San Antonio’s Preferred Gate Parts & Welding Company
We’ve been serving San Antonio homeowners for over 42 years, since 1984. That’s long enough to have worked on the same gates twice - once when they were new, again when they needed welding repair thirty years later. Our technicians know the difference between a gate built for San Antonio’s clay soil and one that was never meant to handle the heave.
Our customers in Alamo Heights and Terrell Hills call us back because we show up when we say we will, we settle on a price before touching a single bolt, and we leave a written 90-Day Done Right Promise on every job. No paperwork to file. No arguing if something isn’t perfect. We come back and make it right.
Most San Antonio calls reach us within three rings, 24 hours a day, 7 days a week. A live person, not a voicemail tree. We dispatch from our local parts inventory, which means most hinge replacements, post resets, and welding repairs finish in a single visit.
Our Gate Parts & Welding Services in San Antonio
Hinge Replacement
San Antonio’s Edwards Aquifer water is among the hardest municipal water in Texas. That mineral load crystallizes inside hinge bearings, seizes bushings, and turns what should be a smooth swing into a grinding, sagging mess. We’ve replaced hinges on gates along Fredericksburg Road and in the 78207 ZIP where the original 1960s hardware had literally fused solid. A typical hinge replacement in San Antonio runs $180-$320 for a standard residential driveway gate, including stainless steel or sealed bearings that hold up better against local water conditions. We match the load rating to your gate’s weight and fabricate shims on-site if the post has shifted off-plumb.
Post Replacement
The clay-and-caliche soil across San Antonio heaves in wet springs and shrinks in scorched summers, progressively tilting posts until the gate drags, binds, or jumps its track. Post replacement with proper concrete pier installation costs $450-$780 in the San Antonio market, depending on gate weight and whether we need to break through caliche to reach stable depth. We’ve reset posts in Terrell Hills where the original installer had simply tamped dirt around a 4×4 - a method that fails in this soil within three to five years. We pour to below frost line and use expansion-rated concrete that moves with the ground rather than cracking against it.
Rail Repair
Bent or cracked rails are common on older San Antonio gates where a vehicle bump, tree limb, or decades of thermal cycling has stressed the metal. Rail straightening and reinforcement welding runs $220-$420, while full rail section replacement on ornate wrought iron typically falls between $340-$580. We match the original profile and weld pattern, critical in historic districts where mismatched repairs draw preservation review scrutiny.
Custom Welding
San Antonio’s deep Spanish colonial heritage produced an unusually high density of ornate wrought iron and tubular steel gates across its inner-city barrios and historic neighborhoods - a pattern far more prevalent here than in Dallas or Houston, where wood privacy gates dominate. These decorative iron gates corrode faster in San Antonio’s notoriously hard Edwards Aquifer water, and they shift off-plumb as the city’s expansive clay-and-caliche soil heaves and shrinks through wet springs and scorched summers, making wrought iron restoration and post re-setting the defining work of local gate repair. Our mobile welding rigs carry MIG, TIG, and stick equipment to fabricate custom pickets, scrollwork, and hinge brackets on-site. Custom welding repairs in San Antonio generally range from $220-$550, with ornate historic reproduction work at the higher end.

Common Gate Parts & Welding Problems We See in San Antonio Homes
- Clay soil heave tilts posts off-plumb. San Antonio’s expansive clay pulls concrete piers upward in wet weather, dropping them in drought. The result is a gate that drags, binds, or won’t latch - and the fix is post re-setting with proper depth and drainage, not just shimming the hinges.
- Hard water mineral scaling seizes hinges and rollers. The Edwards Aquifer deposits calcium and magnesium into bearing surfaces until they lock. On legacy 1970s gates in the 78210 ZIP, we’ve found hinges so seized that disassembly required heat and penetrating oil over multiple hours.
- Thermal stress warps aluminum frames and cracks welds. San Antonio summers above 100°F expand lightweight aluminum gates beyond their design tolerance. Gates originally fabricated for milder climates develop stress fractures at weld joints - and aluminum welding requires equipment most general repair trucks don’t carry.
- Winter freeze events damage automation components. February 2021’s Winter Storm Uri cracked hydraulic lines and fried control boards across the city. We still see LiftMaster and FAAC operators that failed then and were never properly diagnosed - the board looks fine until voltage testing reveals latent damage.

FAQs - Gate Parts & Welding in San Antonio
Yes, we typically specify stainless steel or sealed-bearing hinges for San Antonio’s hard water zones, particularly in the 78207 and 78210 ZIPs where Edwards Aquifer mineral scaling is most aggressive. Standard zinc-plated hinges may seize again within two to three years. Our stainless upgrades carry the same 90-Day Done Right Promise and generally add $40-$60 to the total. Call (833) 754-7503 for an exact quote - estimates are free.
Properties within the King William Historic District (78204) carry preservation review requirements that restrict material substitutions on gates and fencing, complicating what would otherwise be a straightforward swap. Welding repairs must match the original ironwork exactly - same profile, same joint style, same finish - and replacement of entire sections may require Historic and Design Review Commission approval. We’ve navigated this process multiple times and document our work with photographs for preservation files. Call (833) 754-7503 to discuss your specific gate - estimates are free.
Most likely yes. San Antonio’s clay soil swells dramatically in wet spring conditions, tilting posts and distorting the track geometry. We measure post plumb and track alignment before touching the gate itself - replacing rollers or adjusting the operator on a shifted post is wasted money. Post re-setting with proper pier depth runs $450-$780 in San Antonio. Call (833) 754-7503 and we’ll diagnose whether it’s soil movement or a simpler adjustment - estimates are free.
We can diagnose it. The February 2021 freeze caused two failure modes: immediate hydraulic line cracks from ice expansion, and latent control board damage from voltage spikes when power restored. We test LiftMaster, FAAC, and BFT boards under load - a board that passes static testing may still fail under gate motor draw. If the operator is repairable, we stock replacement components. If replacement is more economical, we’ll say so upfront. Call (833) 754-7503 - estimates are free.
Seized hinges from hard water mineral deposits, on gates that have never been professionally serviced. On the west side and south side, we regularly find 1960s-70s wrought iron and tubular steel gates whose original hinges are fused solid - the homeowner has been muscle-forcing the gate for years until the post itself loosens. Early hinge replacement preserves the gate and avoids costlier post work. Call (833) 754-7503 for a free inspection.
