Most gate repairs in Selma run between $180 and $340 before parts, and we typically reach homes near Evans Road, Cibolo Crossing, and the Selma townsite within 60 – 90 minutes of your call. Calder Gate Repair San Antonio dispatches background-checked, uniformed technicians to Selma daily, and every job starts with a written price before any work begins. If your gate is stuck open, grinding, or dead at the opener, call (361) 314-4803 and a live person answers 24/7, not a voicemail.
We know Selma’s gate problems because they follow a pattern. Builder-grade operators installed when most of these subdivisions went in during the 1990s through 2010s are hitting the end of their service life all at once. That means a lot of homes between Lookout Road and Schertz Parkway are dealing with the same failures: stripped plastic gears, dead capacitor boards, and operators that hum but don’t move. We stock the common repair parts for LiftMaster, FAAC, Linear, and DoorKing so we’re not running back and forth to a supply house while you wait.
Why Calder Gate Repair San Antonio Is Selma’s Preferred Gate Repair Company
Selma homeowners keep our number because we don’t run a four-hour arrival window. When you book, you get a live, trackable arrival time, like watching a rideshare pull up. Our technicians arrive in uniform, know the gate opener in front of them, and hand you a written price before a single bolt is turned. That’s the Relay Standard, and it’s how every job runs, start to finish.
Nico Alvarez, who leads our gate repair operation, trains technicians on nine opener brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That matters in Selma because the subdivisions aren’t uniform. A home off Olympia Parkway might have a DoorKing slide operator, while the house behind it runs a vintage FAAC swing arm. We don’t send a generalist who’s meeting your model for the first time. We send someone who has already repaired it this month.
Every repair from Calder Gate Repair San Antonio includes the 365-Day Done Right Promise, written on your invoice. If the repair fails within 365 days, we return at no charge. There’s no fine print to decode. No arguing about whether you “really” had the issue. Just a second visit, free, and the work made right.
Styles & brands we work with


Sliding Gate Repair in Selma
Sliding gate repair in Selma usually points to one of two things: wheels off their track or a rack and pinion system that’s lost its tooth alignment. When post footings shift in the clay soil common to Selma’s newer developments, the rack bar pulls out of square. The pinion gear then chews through teeth instead of driving them smoothly. We realign the track, reset the rack, and sometimes retrofit a heavier-duty wheel assembly so the same shift doesn’t knock it loose again in eight months.
When the Rack Loses Its Teeth
If your slide gate runs a few feet then clunks or jumps, stop running it. Continued use against a misaligned rack destroys the gear set and turns a $240 repair into a $700+ operator replacement. We see this often in Selma where grading settles differently on either side of the driveway, pulling posts toward the curb slope.
Track and Wheel Resets for Sunken Posts
A gate that’s leaning back toward the motor or scraping the ground tells you the concrete pad under the track end has settled. We pull the gate, re-bed the track, and shim the wheels to re-level. Pricing for sliding gate track and wheel work in Selma typically runs $220 – $380 depending on how far the post has moved.
Wrought Iron Gate Repair in Selma
Wrought iron gate repair in Selma is less about ornate scrollwork and more about the hidden steel that holds it up. The hinge post is the failure point. In the original Selma townsite especially, where Cibolo Creek has repeatedly pushed water over its banks, soil moisture sits against the post base and rots it from the inside. You might not see it until the gate sags and won’t latch, but by then the post core is often too far gone to ignore.
When we find rust at the base of a hinge post on one of these older Selma properties, the repair almost always means cutting the post at the root, breaking out the old footing, and setting a new, heavier-gauge post in place. Surface grinding and a coat of paint won’t fix a post that’s lost half its wall thickness. In Selma’s older sections, we quote that work realistically: $400 – $700 per post replacement depending on depth and access. In the newer developments, where the stock is aluminum or powder-coated steel from the 2000s and 2010s, most wrought iron-looking gates are actually lighter steel with a simulated finish. Those hold up better, but the fence attachment points still loosen and crack welds.
Hinge and Post Rehabilitation
Before we weld or replace, we look at the footing. In areas of Selma near the creek and its drainage channels, the footing may have shifted or cracked. Re-welding a gate leaf onto a moving post buys you months, not years. Our price for re-hanging and re-aligning a gate on both hinges runs $190 – $310.
Weld and Rust Repair on the Gate Leaf
For the leaf itself, we grind out rusted seams, weld in patches where the frame has split, and re-coat with a corrosion-resistant primer. On Selma gates with decorative pickets, we often find the bottom rail has rusted through behind the pickets where water can’t drain. We replace the rail section rather than patching over it, so the pickets seat straight and the gate swings true. Weld and rust repair on a wrought iron gate in Selma runs $180 – $450 depending on how much rail has failed.
Trusted Brands We Service in Selma
Selma homes run the whole spread of gate operators, but the ones we touch most are DoorKing slide operators in the gated sections, Linear swing arms in the 2000s-era subdivisions, and Ghost Controls retrofits that homeowners added later. We also service Viking operators on several of the larger lots near the Selma townsite and unincorporated pockets along Evans Road. We keep common boards, gear sets, limit switches, and remotes for these brands on our trucks, so the repair doesn’t wait on a parts shipment.

AfterCommon Gate Repair Problems We See in Selma Homes
- Stripped plastic gears from Selma heat. Thermal expansion in a Selma summer warps cheap internal components. The gear teeth shear off, the motor spins, and the gate doesn’t move. Replacement with metal gearing is the only durable fix.
- Jumpy slide gates on unsettled clay. Selma’s newer developments sit on heavily reworked clay that expands and contracts with rain and drought. Over 15 years, post footings move enough to knock a slide gate off its rack, and you feel it as a clunk mid-travel.
- Solar batteries drained after freezing nights. Selma winters bounce between warm days and nights below freezing. A solar opener with a weak battery will run fine in the afternoon and be dead by morning, leaving the gate stuck at the worst time.
- Hinge post rust near Cibolo Creek. In the original Selma townsite and anywhere the creek has flooded, steel posts wick moisture from the footing. The gate sags gradually, then the latch misses entirely.

FAQs About Gate Repair in Selma
Builder-grade swing operators installed in Selma subdivisions from the 1990s and 2000s commonly fail after 10 – 15 years because Selma’s hot summers thermally expand plastic housing and gears. The plastic gear teeth crack under stress, and the operator burns out its motor trying to move a gate it can no longer turn. We replace these with metal-geared operators and often re-run the low-voltage line that the original builder buried without a protective sleeve. Call (361) 314-4803 and we’ll inspect what you have before recommending a replacement.
Like many homeowners in Selma’s original townsite, you’ll see rust weeping through paint at the post base, often with visible flaking or a soft, spongy feel when tapped with metal. If the gate has started sagging toward the latch post, the footing core is likely compromised. This is not a surface issue in Selma’s flood-prone sections of the townsite. We replace the post and re-bed the footing for $400 – $700. Estimates are free, so call (361) 314-4803 and we’ll tell you if surface rust is all it is.
Yes, and we do this regularly in Selma, especially in newer subdivisions where the builder installed a manual gate but the homeowner now wants phone control and keypad entry. We add a Ghost Controls or LiftMaster operator, run the low-voltage power from the house or a solar panel array, and program the opener to a new keypad and app. Most retrofits run $800 – $1,200 installed. The 365-Day Done Right Promise covers the entire job.
Yes, usually. When Selma’s clay soil shifts post footings by even half an inch, the rack bar moves out of square with the pinion gear. The gate then jumps teeth or pushes the wheel off the track. Continuing to run it will destroy the gear set. Our repair is to re-align the rack, reset the wheel assembly, and re-bed the track end if it has settled. That work in Selma runs $220 – $380. Call (361) 314-4803 with the gate make, if you know it, and we’ll get you on the schedule.
They work if the panel faces south and the battery is healthy, but Selma’s winter mix of cloudy stretches and freezing nights kills aging solar batteries fast. We see dead openers most often on north-facing fences or under tree cover, which is common in Selma’s established neighborhoods near Evans Road. If your solar gate is unreliable, we test the battery and panel output and either replace the battery or convert the gate to a hardwired low-voltage run. A solar battery replacement runs $180 – $320.
