AfterFast, Reliable Gate Motor & Opener Across Altadena
A gate motor or opener replacement in Altadena typically costs $450-$1,200 for the operator itself, with installation labor adding $300-$600 depending on gate weight, post condition, and whether fire-access upgrades are required. Most motor repairs we handle run $180-$400 and are done on the first visit, because we stock common FAAC, BFT, Linear, and Viking parts in the van. If your gate won’t open in Altadena right now, call (877) 610-2993 and you’ll reach a live person who knows this area, not a voicemail queue. Hal Gatewood has been fixing gates in the San Gabriel foothills since 2001, and when we make a promise about a repair window to someone off Lake Avenue or up near the Cobb Estate, we keep it.
Why Gatewood Fence & Gate Is Altadena’s Preferred Gate Motor & Opener Company
Altadena is different from the flatland cities below it, and most gate companies don’t adjust for that. We do. This is unincorporated LA County, not Pasadena. Permits, inspections, and post-2025 fire-access requirements come through the LA County Department of Regional Planning, and the minute a contractor starts treating this like a Pasadena job, the homeowner is the one who pays for it later. We’ve worked with enough Altadena property owners on 91001 and 91003 hillside lots to know exactly how the county reviews gate installation in Altadena on fire-affected parcels, and we quote for that reality up front.
Our reputation for Altadena gate repair comes from showing up when we say we will and refusing to sell a full replacement when a rebuilt motor or corrected post will do the job. Hal is the owner, and you can drive to the shop and look him in the eye. That’s the oldest accountability there is, and it matters more when the gate on a long sloped driveway is the first thing standing between your house and the street. Every job carries our 90-Day Done Right Promise in writing. One call brings Hal back, no runaround.
Our Gate Motor & Opener Services in Altadena
Motor Repair
Most Altadena gate motor failures start as a post or hinge problem, not a motor problem. When the gate binds against a shifted post, the operator draws more current, overheats the control board, and burns out. We fix the alignment first, then repair or replace the motor. A typical motor repair in Altadena runs $180-$400 including parts and labor, and most jobs are finished the same visit. We repair before we replace, because a new motor on a bound gate fails the same way the old one did.
Slide Motor Installation
Slide gates suit a lot of Altadena hillside properties where there’s simply no room for a swing panel to arc across a sloped driveway apron. We install and service slide motors for rack-and-pinion and chain-drive systems, and we stock the common gear racks and hardware so we aren’t ordering parts and leaving you waiting. A slide motor replacement in Altadena generally falls between $600 and $1,100 installed, more if the existing rail is worn or the gate track needs leveling. The price is quoted and agreed before we start any work.
Linear Motor
Linear motors are simple, direct-drive units that work well on lighter gates, but on a heavy ornamental iron Altadena gate, the linear shaft can wear out fast. We service and replace Linear brand operators regularly, and Hal carries the common board replacements and limit switches in the van. If you have a Linear opener that’s humming but not moving, or reversing mid-travel, call us before you force it: the repair is usually under $300, and forcing the gate usually costs more.
Battery Backup
Given where Altadena sits, this one isn’t optional. Santa Ana wind events take down power lines and take down transformers, and an electric gate with no backup means a car stuck on the wrong side of the house. We install battery backup units on new and existing operators, most often on FAAC and LiftMaster systems. Expect $350-$650 for a quality battery backup installed, and we’ll test it under load before we leave. Your gate should still work when the rest of the street is dark.
Every service call starts with an honest assessment. If your gate can be saved, we’ll save it. If replacing the operator is genuinely the cheaper answer, we’ll tell you that too, and we’ll write the price down before any work begins.

Trusted Brands We Service in Altadena
We’re certified to service nine major gate brands, but around Altadena the ones that show up most on 1920s through 1950s hillside homes are FAAC, BFT, and Linear, with Viking operators on a handful of larger estate gates. We keep the common boards, limit switches, and remotes for these brands stocked locally, so we aren’t making a second appointment just to come back with a part. If you’ve got an older operator that a national company told you is “obsolete,” call us first. Hal has been repairing what other companies want to replace since 2001, and a board-level repair on a FAAC or BFT unit is often $150-$350 where a full operator replacement is four times that.
Common Gate Motor & Opener Problems We See in Altadena Homes
- Fire-damaged operators on Eaton Fire rebuilds. Melted control boards, heat-seized hinges, and warped aluminum frames don’t get repaired, they get replaced, and LA County now requires those replacements to meet current fire-access gate standards. This applies even if the original gate predated those rules by decades.
- Santa Ana wind damage. Sustained gusts funneling down the San Gabriel canyons onto Altadena shear hinge bolts, rack wooden gate frames, and burn out swing-gate operators in a single storm. Older gates with worn rack-and-pinion gears are the first to fail.
- Clay soil and root intrusion shifting gate posts. Decades of expansive clay movement and oak or eucalyptus roots have knocked thousands of Altadena gate posts off plumb. A post that shifts an eighth of an inch binds the gate, which strips the operator gears over time.
- Legacy operators with no safety features. Many Altadena gates were hung before modern photocell and obstruction-detection requirements existed. We regularly retrofit these, and in some cases LA County fire-access standards now mandate it.
Pricing for Gate Motor & Opener in Altadena, CA

FAQs - Gate Motor & Opener in Altadena
Yes, in many cases it does. Altadena is unincorporated LA County, so gate permits and inspections run through the LA County Department of Regional Planning, not any city building department. Since the January 2025 Eaton Fire, LA County is applying current fire-access gate standards to replacements on fire-affected properties, including Knox-Box provisions and minimum clearances for fire apparatus. We’ll tell you before we start whether your job triggers those requirements, and we’ll quote for them up front. Call (877) 610-2993 and we’ll walk you through it.
Because those sustained gusts funnel directly down the San Gabriel Mountain canyons onto Altadena, and they hit with more force than what Pasadena flatlands get. The wind loads push hard against a swing gate panel, and the operator fights back until the motor overheats or the gears strip. Gates with worn rack-and-pinion hardware or a slightly misaligned panel are the first to burn out. We see it every fall and winter.
You can usually retrofit. Safety photocells, obstruction-sensing operators, and keypad access can all be added to an older ornamental iron gate without pulling it out and starting over. We reset posts, re-hang hinges, and fit current-spec operators on pre-safety-era gates regularly, preserving the original iron. When fire-access standards require a wider opening or a different swing direction, replacement becomes the only compliant option, and we’ll tell you plainly which situation you’re in.
The big thing is that melted control boards, heat-seized hinges, and warped frames mean a full operator replacement, not a repair, and LA County will require that Altadena gate parts and welding work to meet current fire-access gate standards. Your insurance rebuild scope should include gate hardware, operator, and any needed Knox-Box provision or clearance widening. If your adjuster is using pre-fire prices, we can provide a written estimate that reflects current requirements. Get a free second opinion on any estimate you’re given.
Because Altadena’s expansive clay soils move with moisture, and the large oaks and eucalyptus trees sink roots into the footing and shift things over time. If a post keeps drifting, the issue is in the footing, not the hinge hardware. We dig out and reset the post footing with proper pour depth and drainage, which is the only fix that lasts. Show me a gate closing on its own and I’ll show you where it’s failing. To schedule a post reset or any Gate Motor & Opener work, call (877) 610-2993.
