AfterFast, Reliable Gate Motor & Opener Across San Anselmo
Gate motor and opener repair in San Anselmo typically runs $225-$475 for most service calls, and we can usually get to homes in the 94960 and 94979 ZIP codes the same day you call. If your gate won’t open after a winter storm or the motor is grinding but nothing moves, call us at (877) 610-2993. We’ve been fixing gates around San Anselmo long enough to know that the problem usually starts at the post, not the motor itself.
Our Gate Motor & Opener crew knows the streets, the soil, and the older wooden gates that dominate this town. When a creek-corridor lot shifts after heavy rain, the motor takes the blame but the footing is the culprit. Hal Gatewood has been owner-operating this company since 2001, and he still answers the phone. No voicemail. No call center. Just someone who knows San Anselmo gates.
Why Gatewood Fence & Gate Is San Anselmo’s Preferred Gate Motor & Opener Company
San Anselmo homeowners have been calling us for years because we do something most gate companies won’t: we fix what’s there before we talk about replacing it. If a motor can be rebuilt, we rebuild it. If a hinge post is heaving out of the ground, we address the footing instead of slapping a bigger motor on and hoping for the best. Homeowners on streets like Butterfield Road, Red Hill Avenue, and the flats near downtown have seen us do this work in their driveways, not haul a gate back to some shop off Highway 101.
Our calls are answered by a live person around the clock because a gate stuck half-open at 11 p.m. is not a voicemail problem. The person who shows up is background-checked and uniformed, and every job carries the 90-Day Done Right Promise in writing. If it’s not done right, one call brings us back. No runaround.
We publish our address and license number. Hal’s name is on the shop and on every invoice. That’s the kind of accountability you can drive past and see with your own eyes.
Our Gate Motor & Opener Services in San Anselmo
Motor Repair
Most San Anselmo motor failures start with water. Rain gets into the housing, corrosion eats the contacts, and the motor works until it doesn’t. We open the unit, clean the contacts, replace corroded wiring, and test the capacitor and limit switches before we tell you anything needs replacing. A typical motor repair in San Anselmo runs $195-$380 depending on what we find. Flood-saturated ground adds another layer: if the post has shifted, we address that first so the repaired motor doesn’t burn itself out fighting a misaligned gate.
Motor Installation
When a motor truly is beyond saving, we install a new one properly. That means running dedicated conduit for the power, setting the mounting plate level on a stable post, and programming the travel limits so the gate doesn’t slam or stall. Motor installation in San Anselmo typically runs $900-$1,700 for a single swing gate, including the operator. We always quote the full price and get your agreement before any work begins. No surprises at the door.
Linear Motor
Linear arm operators are common on the long driveway gates you see in the Sleepy Hollow area and up in the hills west of downtown San Anselmo. These motors push and pull through a threaded arm, and when a post heaves even slightly out of plumb, the arm binds and strips the gear. We stock Linear replacement arms and control boards locally, so a repair on a Linear motor in San Anselmo usually happens same-day, in your driveway. Expect $260-$520 for most Linear arm motor repairs.
Slide Motor
Slide gates sit on a track, and that track is the weak point in San Anselmo. Debris from creek flooding bends the rail, and the motor strains to push the gate past the obstruction. We repair or replace bent track sections, re-align the gate rollers, and re-program the motor so it travels the full length without tripping the safety photocell every time. Slide motor repair in San Anselmo typically costs $240-$480, more if the track needs replacement. Battery backup systems are also available for slide gates, so a power outage doesn’t lock you out or in.

Trusted Brands We Service in San Anselmo
We’re certified to work on nine major gate brands, including FAAC, BFT, Linear, and Viking. When a San Anselmo homeowner calls about a FAAC hydraulic operator that’s leaking or a Viking control board that won’t respond, we can usually source the part locally or have it in hand within a day. We don’t push you toward a brand we prefer; we fix the one you have. Hal has worked on most of these systems since they first hit the market, and there isn’t much he hasn’t seen.
Common Gate Motor & Opener Problems We See in San Anselmo Homes
- Post heave from saturated soil. Flood-saturated ground around San Anselmo Creek and Sir Francis Drake Boulevard shifts even concrete-set posts, throwing swing gates out of alignment. The motor binds, the rack and pinion strips, and it sounds like gears grinding. We re-set the footing with gravel drainage and a deeper pour before re-mounting the operator.
- Bent slide gate tracks after debris impact. During creek flood events, branches and debris slam into slide gates near the downtown corridor. The track bends, the gate can’t travel, and the motor overheats trying. We straighten or replace the track and test the full travel before we leave.
- Corroded hinge pins on older Craftsman gates. San Anselmo’s early-20th-century bungalows often have original wooden gates with iron hinge pins that rust through in wet winters. Waterlogged bottom rails and seized hinges overload the motor, which fails prematurely. We lubricate, replace pins, and sometimes rebuild the bottom rail so the gate swings freely.
- Battery backup failure after storm outages. Power cuts during winter storms in San Anselmo mean your gate opener runs on battery, and many backup batteries were never maintained. We test the battery, replace it if it’s dead, and make sure the manual release works so you’re never stuck.

FAQs - Gate Motor & Opener in San Anselmo
Flood water from San Anselmo Creek saturates the soil around your gate posts, causing them to heave and shift out of plumb. That movement binds the motor and throws the rack and pinion out of alignment, which strips gear teeth and burns out the motor. Debris carried by the flood also bends slide gate tracks and can knock photocells loose. After a flood event, the motor is usually the symptom, while the footing and track are the actual problem. Call (877) 610-2993 and we’ll inspect the post, the track, and the operator together.
Use the manual release handle or key to disengage the motor and open the gate by hand. Do not force the gate if it won’t move; the post may have shifted and you’ll damage the opener. If your gate has a battery backup system, it should open and close normally for a limited number of cycles. After power returns, test the gate manually before re-engaging the motor. If it binds or grinds, call us and we’ll check the alignment before the motor eats itself.
Because the ground under San Anselmo swells when it’s wet and shrinks when it’s dry. During winter rain, the soil around your hinge post absorbs water and the post moves enough to bind the gate against the motor. The swings you feel in summer don’t happen because the post settles back. The fix is a proper footing assessment, not a bigger motor. We re-set posts with gravel drainage and deeper concrete so the gate has room to move without fighting itself.
Yes, solar openers work fine on older wooden gates in San Anselmo, as long as the gate isn’t too heavy and the post hasn’t rotted. We’ll check the post condition first because a solar motor can’t overcome a sagging, waterlogged gate. If the wood is sound, a solar operator with a battery backup will open and close the gate through most winter conditions, though we add a low-voltage trickle charge for the darkest weeks in the Ross Valley. Installation runs $950-$1,800 depending on the gate weight and panel placement. Call (877) 610-2993 for a free assessment.
Test the gate manually first. Disengage the motor and push the gate open and closed. It should move easily, without binding or grinding. If it doesn’t, the post or track is out of alignment and the motor is at risk of burning out. Then re-engage the motor and watch it travel; it should move smoothly and stop at the correct limits. Listen for grinding, clicking, or a motor that strains. Any of those signs means a service call is cheaper than a full replacement. We’ll walk you through the check over the phone at (877) 610-2993 if you’re not sure.
