We make the short drive from Palo Alto to San Anselmo regularly, and after 16 years of gate-only work, we’ve learned this town’s failure patterns by heart. The Ross Valley’s wet-dry cycle, the creek’s flood history, and the prevalence of pre-WWII homes on sloping lots create gate problems you won’t find in coastal Marin or the flatter parts of San Rafael. Our Gate Repair team doesn’t guess—we diagnose based on what we’ve actually seen fail on San Anselmo properties.
San Anselmo residents call us because general contractors and fence companies treat gates as an afterthought. Kevin Lewis, our owner and lead technician, handles every diagnosis personally. We’ve got 542 verified reviews averaging 4.9 stars, and a substantial share come from repeat customers in the Ross Valley who learned the hard way that a handyman with a drill isn’t the same as a gate specialist with in-house welding capability and fluency across nine major brands.
Why Golden State Gate Solutions Palo Alto Is San Anselmo’s Preferred Gate Repair Company
Our reputation in San Anselmo was built one sagging gate at a time. Kevin and his team have re-set dozens of posts along the Sir Francis Drake corridor after winter floods, replaced rotted hinge hardware on 1920s bungalows in the flats, and realigned uphill-swinging panels on terraced lots throughout the 94960 ZIP code. Customers here refer us because we show up, identify the actual failure, and fix it without pushing unnecessary replacements.
Those 542 verified reviews with a 4.9-star average include a growing number from San Anselmo and Fairfax homeowners who initially called a general fence contractor and ended up with us after the job was referred out or botched. We’re typically on-site in San Anselmo within 90 minutes of a call, and we carry parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule—so most repairs don’t require a return trip.
What separates us in this market is genuine category depth. We don’t do garage doors. We don’t build decks. We’re gate-only specialists, and that focus means Kevin recognizes San Anselmo’s specific failure modes—clay-soil heaving, moisture-trapping canopy, undersized vintage hardware—before he’s even out of the truck.
Our Gate Repair Services in San Anselmo
Hinge Repair
The early-20th-century Craftsman bungalows and Victorian cottages that dominate San Anselmo’s housing stock were often built with gates that swing uphill from the street to terraced yards. Original hinge hardware was never sized for that torque, and decades of wet-dry cycling have corroded what remains. We replace undersized or rusted hinges with properly rated hardware—sometimes upgrading to stainless steel on north-facing lots where galvanized steel won’t survive another season under mature redwood canopy. A typical hinge repair or upgrade in San Anselmo runs $280–$580.
Post Repair
This is where San Anselmo’s geography hits hardest. San Anselmo Creek’s documented flooding along Sir Francis Drake Boulevard and surrounding low-lying streets saturates the clay subsoil, which swells, heaves posts out of plumb, then shrinks and leaves voids. We’ve re-set posts on the same properties multiple times after major flood seasons. Our approach: excavate to stable depth, set in concrete with proper drainage, and sometimes install longer posts or additional bracing where the soil cycle is aggressive. Post repair or replacement in San Anselmo typically costs $650–$1,400 depending on depth, access, and whether we’re working around mature landscaping.
Weld Repair
Our in-house welding capability matters on San Anselmo’s older iron and steel gates, many of which have developed stress cracks at frame joints after years of operating out of alignment. Rather than subcontracting or declaring the gate unrepairable, Kevin can reinforce frames, repair broken welds, and extend the service life of gates that other companies would replace. A frame weld repair with realignment generally runs $480–$920 in this market.
Gate Realignment
Realignment is the most common service call we get in San Anselmo after winter. When posts heave, hinges corrode, and boards warp, the gate stops latching, drags, or binds against the frame. We measure the root cause—whether it’s post plumb, hinge wear, or frame twist—and correct it systematically. Realignment alone typically costs $320–$650, though if post heaving is severe, we’ll quote the full repair so you’re not calling us back in six months.

Trusted Brands We Service in San Anselmo
We stock and service LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Most local competitors carry parts for two or three brands at most; we maintain inventory across all nine because San Anselmo’s mix of original installations, homeowner upgrades, and property-manager standardization means we never know which brand we’ll encounter. That depth eliminates the “we’ll order that and come back next week” delay. Whether it’s a failed FAAC hydraulic operator on a commercial driveway in the 94979 ZIP or a Ghost Controls solar opener on a residential hillside gate, we diagnose, source, and repair without referral.
Common Gate Repair Problems We See in San Anselmo Homes
- Corroded hinge hardware on uphill-swinging gates. The torque of a panel swinging against gravity overwhelms original or undersized hinges, especially after decades of moisture exposure. We regularly find 80-year-old hinge brackets with ⅛-inch of material left.
- Post heaving from flood-saturated clay soils. After each significant winter, gate posts along Sir Francis Drake Boulevard and adjacent valley-floor blocks shift out of plumb. Re-plumbing and re-setting posts has become a predictable late-winter service pattern specific to these streets.
- Warped wooden boards that never fully dry. North-facing lots shaded by mature redwood and oak canopy trap marine moisture from the Ross Valley’s funneled storm systems. Wood gate boards swell, warp, and rot faster than on exposed south-facing properties in Fairfax or the hills above San Rafael.
- Failed automatic openers in flood-prone installations. Control boxes and motors mounted too low or without proper weatherproofing take on moisture during high-water events. We relocate, reseal, or replace with appropriately rated hardware.

We provide upfront pricing before any work begins—call (831) 218-8355 for a free estimate at your San Anselmo property.
We recently realigned a heavy wooden swing gate on a 1920s Craftsman bungalow on Sir Francis Drake Boulevard. The gate’s hinge hardware had corroded from repeated flood-season moisture and the posts had heaved 2 inches out of plumb due to swelling clay. We re-set the posts in concrete, replaced the galvanized hinge brackets with stainless steel, and reinforced the gate frame—the homeowner avoided a full replacement for $1,800.

FAQs — Gate Repair in San Anselmo
Your posts shift because San Anselmo Creek’s flood-prone clay soils along Sir Francis Drake Boulevard and surrounding low-lying streets swell when saturated, heaving posts out of plumb, then shrink during dry months leaving voids that let posts tilt further. This is a valley-floor failure pattern specific to San Anselmo’s geography—uphill neighbors in Fairfax or the hillside areas of San Rafael largely don’t experience it. We address it by setting posts deeper, using concrete with proper drainage, and sometimes adding bracing where the soil cycle is most aggressive. Call (831) 218-8355 for an assessment—estimates are free.
We can often match or closely approximate original hardware, and when we can’t source vintage pieces, we fabricate equivalents in our shop or upgrade to modern hardware that preserves the gate’s appearance while handling actual loads. Many San Anselmo Craftsman gates were built with decorative but undersized hinges never intended for uphill-swinging panels—we’ll show you the original versus what the gate actually needs. Call (831) 218-8355 and Kevin will evaluate what’s salvageable.
Usually not. Warped boards on San Anselmo gates are typically caused by the Ross Valley’s pronounced wet-dry cycle, especially on north-facing lots shaded by mature redwood and oak where wood never fully dries between storms. We often replace individual warped boards, reinforce the frame, and improve drainage or sealing to prevent recurrence. Full replacement is only necessary when rot has compromised structural members or the frame itself is twisted beyond correction. Most board-and-frame repairs run $480–$1,100 versus $2,800+ for a quality replacement. Call (831) 218-8355 for an honest assessment.
Yes, and we specifically address the moisture and debris-strike risks that come with San Anselmo’s flood history. We relocate control boxes above historical high-water marks, upgrade to weatherproof-rated enclosures, and stock sealed motors from LiftMaster, FAAC, and DoorKing designed for challenging environments. If your opener failed after a high-water event, we’ll determine whether it’s a motor issue, control board damage, or wiring corrosion—then fix it without replacing components that are still good. Call (831) 218-8355 for same-day diagnosis.
Repair is sufficient when the frame is structurally sound, the posts are stable (or can be stabilized), and the failure is isolated to hardware, a motor, or localized rot. Retrofit makes sense when multiple systems have failed simultaneously, the frame is twisted beyond welding correction, or you’re repeatedly repairing the same gate because the original design can’t handle current use. Kevin evaluates this on every San Anselmo call—we’ll show you exactly what’s failing, why, and what repair versus replacement costs. No replacement gets recommended unless repair is genuinely uneconomical. Call (831) 218-8355 for a free evaluation.
