Why Calder Gate Repair Is Antioch’s Preferred Gate Repair Company
Antioch homeowners deal with something most gate companies don’t plan for: expansive clay soil. The ground here moves. It swells in Delta winters and shrinks in dry summers, and that movement slowly works against every gate post and operator in your yard. Our Gate Repair team knows this before we arrive. We check the footing first, because a gate that sags at the hinge post is usually a post problem, not a panel problem.
Every Antioch job runs through The Relay Standard: a live arrival time, before-and-after photos, and a digital invoice you pay from a link. No paper scraps. No mystery charges. The price we quote at the door is the number on the invoice. That’s it.
We’re part of the Relay Home Co. family, established 2009. Calder Gate Repair is independently owned and operated, and the Antioch crew is factory-familiar with Linear, Viking, Ghost Controls, and DoorKing openers, among others. Homeowners off Lone Tree Way, near the Delta, and up by the Black Diamond foothills call us because we diagnose the real cause the first time – not just the symptom.
Metal Gate Repair in Antioch
Metal Gate Repair in Antioch usually means one of three jobs: a sagging steel or wrought iron panel, a failed weld at the hinge or latch, or rust that’s eaten through a post base. We cut out the bad section, reinforce the frame, and repaint to match. On older Antioch properties, especially those with original ornamental gates near downtown, we often find the post itself has been pushed out of plumb by soil movement. That has to be corrected before the panel can hang right.
Hinge and Post Correction
When a metal gate drags on the latch side, the hinge post has typically moved. Antioch’s clay soil expands in winter and contracts in summer, so posts set at shallow depths heave a little more each year. We reset the post at depth – often 30 inches or more – and re-hang the gate so it swings clean. If we skip the post and just adjust the hinges, you’re calling us again in six months.
Weld and Rust Repair
Delta moisture accelerates rust on exposed metal gates, especially within a mile or two of the water. We grind back the corrosion, weld in new steel where the section is compromised, and use a rust-inhibiting primer before the finish coat. A typical weld and rust repair on a single-drive gate in Antioch runs $220 to $390, depending on how much steel needs replacing.
Wood Gate Repair in Antioch
Wood Gate Repair in Antioch has its own seasonal rhythm. In winter, wood gates absorb moisture from Delta fog and rain, swelling until they stick against the frame. In summer, they dry out and shrink, leaving gaps and loose hardware. A sagging wood gate on a home near the Contra Loma area usually needs more than a hinge adjustment. The real fix is a diagonal brace, new hardware, and often a post re-set.
Swollen and Sticking Panels
A wood gate that won’t close in January is nearly always a moisture problem. The panel has swollen past its clearance, and the latch no longer lines up. We plane the edge, re-seal the wood, and re-align the latch so the gate works year-round. Better yet, we’ll tell you if the panel should be replaced with a composite or cedar option that handles Antioch’s humidity swings without moving.
Weight and Operator Strain
Swollen wood gates get heavier. A lot heavier. That extra weight strains the operator arm and can trip the loop detector or burn out the motor entirely. On wood gate jobs in Antioch, we check the operator load after every repair. If the motor is pulling more current than it should, we’ll tell you before it fails. Most wood gate panel repairs run $180 to $320, and operator replacements start around $450 plus the cost of the new unit.
Trusted Brands We Service in Antioch
We repair openers from Linear, Viking, Ghost Controls, and DoorKing, plus LiftMaster, FAAC, BFT, Elite, and Mighty Mule. That matters in Antioch because many local homes have one of the Viking or DoorKing units sold through Bay Area gate installers over the years, and parts for those aren’t sitting on a shelf at the big box stores. We keep common components in our service vehicles, so repairs off Buchanan Road or down by the marina don’t wait on a parts shipment from across the country.
Common Gate Repair Problems We See in Antioch Homes
- Post footing heave from expansive clay: The gate sags or binds at the hinge post even when the panel is straight. Fixing the panel without the post is a repeat call, so we check the footing first.
- Operator strain from swollen wood gates: Winter moisture makes wood panels heavier, overloading the gate motor and tripping the loop detector or burning out the motor. We test the load after every repair.
- Safety photocell misalignment: When the post shifts, the photo-eyes drift out of line. The gate reverses erratically or refuses to close – a common complaint on older Antioch installs near open fields where the ground moves freely.
- Rack and pinion jumps on slide gates: Ground movement throws the rack out of alignment, and the gear slips. We re-set the rack and re-aim the photocells, but the footing correction is what keeps it from happening again.
Our tech got called to a home off Lone Tree Way where a LiftMaster slide gate had jumped the rack and pinion and was grinding against the hinge post. We pulled the operator, found the post footing had shifted nearly two inches from soil movement, re-poured the footing at the correct depth, re-set the rack, and re-aimed the safety photocells. The gate now runs clean and reverses on command. That’s the difference between patching a symptom and fixing the cause.

FAQs About Gate Repair in Antioch
The hinge post has almost certainly moved in the clay soil. This is the most common gate failure we see across Antioch, from homes near Lone Tree Way to properties closer to the river. The fix is a post re-set at depth, usually 30 inches or more, with proper concrete. Call (903) 417-0793 for a free estimate, and we’ll confirm the diagnosis on site.
Yes. Any automatic gate installed in California must have photo-eyes and meet UL 325 safety standards, which require the gate to reverse when it encounters resistance or when the photo-eye beam is broken. If your gate refuses to close or reverses for no reason, the photo-eyes are likely misaligned from post movement. We re-aim and test them on every repair.
Disconnect the operator arm and push the gate by hand. If it moves freely, the gate is fine and the operator or its settings are the issue. If it binds, drags, or sags, the gate itself – usually the post – needs work before you spend money on a new motor. We do this test first on every Antioch call, because a replacement operator on a bad post is wasted money.
Yes, and we do a lot of these in Antioch during the wet months. We plane the edge, re-seal the wood, and re-align the latch so the gate closes clean. We also check the operator load, because a heavier wet gate can burn out the motor over time. Most wood panel repairs run $180 to $320. Call (903) 417-0793 and we’ll give you a written price.
We install new gate operators, including Linear, Viking, Ghost Controls, and DoorKing, but we don’t do same-day installations. Installation requires measuring the gate, checking the post, running power, and configuring safety edges and reversal testing. We’ll schedule a free measure, give you a written price with a timeline, and book the install when it works for you. Call (903) 417-0793 to get started.
