Why Liberty Gate Repair San Francisco Is Concord’s Preferred Gate Repair Company
We’ve been working on gates for over 31 years — exclusively gates, not fences or general construction — and that depth shows when we pull up to a Concord home and recognize the exact hinge pattern on a 1970s wrought-iron driveway gate or know which LiftMaster operator model was original to the 94520 tracts. Steven Lee, our owner and lead technician, is the person who answers your questions, diagnoses the problem, and handles the repair. That matters in Concord, where the same clay-soil and heat issues show up again and again, and you want someone who’s seen the pattern before.
Our 613 verified reviews average 4.9 stars — not from a lucky month, but from hundreds of real jobs where homeowners specifically mention showing up prepared and fixing it without return visits. We stock parts for nine major brands and weld on-site, which means when we come to Concord, we come ready to finish.
Our Gate Repair Services in Concord
Gate Realignment
Gate realignment is our most common call in Concord from February through April, and there’s a reason local techs know to book up fast. The first sustained winter rains cause the region’s expansive clay soils to swell and physically push gate posts out of plumb — often overnight. We were called to a 1965 ranch home on Avon Avenue in Concord’s 94521 tract where the original one-piece wood side gate had dragged for weeks after winter rains heaved the shallow-set posts out of plumb. The homeowner couldn’t latch it, and the 40-year-old gate opener’s motor was running hot in the 100°F summer heat. We realigned the posts by excavating and repouring concrete footings 36 inches deep, replaced the worn LiftMaster chain, and advised retrofitting to a modern dual-track system to prevent future heave issues. A typical realignment with footing correction in Concord runs $450–$650.
Hinge Repair
Concord’s 40–60-year-old wood gates, common across the 94519, 94520, and 94521 ZIP codes, develop hinge failure from a combination of wood shrinkage in dry summers and the constant stress of dragging against misaligned frames. We replace with heavy-duty ball-bearing or greaseable hinges sized to the gate weight, not the generic hardware-store pair that failed. Most hinge repairs in Concord are $180–$320 and take under two hours.
Post Repair
The shallow footings from Concord’s 1960s–70s building boom — often just 12–18 inches deep — were never meant to resist Diablo Valley clay. We excavate to 36 inches minimum, use concrete rated for expansive soil, and sometimes add steel post anchors for gates that have heaved repeatedly. Post repair with new footing in Concord typically runs $380–$580.
Weld Repair
Wrought-iron and steel gates across Concord’s older neighborhoods develop cracks at stress points — often where a previous homeowner welded a quick fix that didn’t penetrate properly. We bring a 220-volt portable welder and match filler metal to the original gate material. Most on-site weld repairs in Concord are $200–$400.

Trusted Brands We Service in Concord
We’re factory-familiar with nine major gate brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That matters in Concord because so many homes still run original operators from the 1990s and 2000s — LiftMaster swing-gate operators are especially common in the 94518 and 94521 tracts — and knowing whether a part is still manufactured or requires creative sourcing saves you from an unnecessary full replacement. We stock common operator parts, chain assemblies, and control boards, so Concord customers aren’t waiting a week for a relay or limit switch to ship from Southern California.

Common Gate Repair Problems We See in Concord Homes
- Clay-soil heave after winter rains pushes gate posts out of alignment, causing chronic dragging and latching failure. This is essentially a non-issue for contractors working the sandier Peninsula soils, but in Concord it’s the dominant spring repair driver.
- 100°F+ summer heat warps 40–60-year-old wood gates, binding them in their frames and overstressing older gate openers. The temperature swing from a 55°F January morning to a 105°F August afternoon is brutal on unsealed wood.
- Shallow 1960s–70s footings cannot resist soil expansion and contraction, leading to repeated leaning and binding even after “simple” realignments. Temporary fixes fail because the root cause is underground.
- Original gate openers running past their 15–20 year service life with obsolete circuit boards and no available replacement parts. We help Concord homeowners decide whether to source a compatible retrofit controller or replace the entire operator.

FAQs — Gate Repair in Concord
Concord’s expansive clay soils absorb winter rainfall and swell, physically pushing shallow-set gate posts out of plumb. This failure spike is unique to clay-soil inland valleys and essentially unknown in sandier coastal areas. The 1960s–70s tracts across 94519, 94520, and 94521 are especially vulnerable because original footings were rarely deeper than 18 inches. If your gate started dragging after the first heavy rains, the soil moved your posts — not the gate itself. Call (628) 261-6223 and we’ll assess whether realignment or deeper footings are the right fix.
We can often plane, rebrace, and rehang a warped wood gate if the frame is structurally sound, typically $280–$450. However, if the wood has checked deeply or the frame rails are rotted at the joints, we may recommend replacement — especially if the gate is exposed to Concord’s full afternoon sun without shade. We’ll inspect and give you an honest assessment before starting. Call (628) 261-6223 for a free look.
We stock common LiftMaster parts including chain kits, limit switches, and control boards for operators from the 1990s through current models. For very old units where parts are obsolete, we can often source compatible aftermarket controllers or recommend a retrofit that preserves your gate hardware. Steven carries a full parts inventory on his service vehicle for Concord calls. Call (628) 261-6223 with your operator model number.
36 inches minimum for standard residential gates in Concord’s high-shrink-swell clay, and deeper for heavy solid-core or automated gates. The original 12–18 inch footings from the 1960s–70s building boom were adequate for the sandy loam spec sheets of that era, not for Diablo Valley clay. We excavate to undisturbed soil, use concrete with proper slump for expansive conditions, and sometimes add steel post anchors for gates with a history of repeated heave. Call (628) 261-6223 if your posts have leaned more than once.
No — installing a new operator on a sagging or misaligned gate will strain the motor and likely fail within a season. The gate must move freely through its full arc before any operator, new or old, can work reliably. In Concord, we see this mistake often: homeowners replace a burned-out operator when the real issue is posts heaved by clay soil or a warped gate binding in summer heat. We diagnose the root cause first, fix the mechanics, then match an operator to the corrected gate. Call (628) 261-6223 for a proper assessment — estimates are free.
