We know Tamalpais Valley’s driveways better than most gate companies ever will. The fog that rolls down this canyon every morning, the steep grades climbing off Panoramic Highway, the 1950s hillside homes with narrow shoulders and no pullout space. None of that is an obstacle if you’ve been doing this work here as long as we have. It’s just the job.
Why Gatewood Fence & Gate Is Tamalpais Valley’s Preferred Gate Installation Company
Hal Gatewood has been running this shop since 2001, and his name is on the building and every invoice. That matters in Tamalpais Valley, where homeowners have learned to be skeptical of outfits that quote one number over the phone and show up with another. We don’t operate that way. The price we write down is the price you pay, and it’s agreed before we touch a single post.
Beyond the paper and the promise, there’s the simple fact that we show up. Tamalpais Valley sits inside the 94941 zip and runs along Tennessee Valley Road, Shoreline Highway, and the winding lanes off Panoramic Highway. Our crew knows those roads, knows where the fog sits hardest, and knows which driveways have the kind of grade that requires slope-compensated hardware instead of a stock opener arm. That local knowledge isn’t something you can get from a national outfit. It comes from years of unsticking gates on hillsides like yours.
Every job carries the 90-Day Done Right Promise in writing. If something isn’t right, one call brings Hal back. No fine print, no “under most circumstances.” He means it.
Our Gate Installation Services in Tamalpais Valley
We handle the full range of gate work you’ll find in Tamalpais Valley, from a simple pedestrian gate off a backyard path to an automated double gate across a steep driveway. Here’s what that looks like on the ground.
Driveway Gate
Most driveway gates in Tamalpais Valley need more than a stock frame. The driveways here climb, and a gate that works fine on flat ground will bind partway up a slope in this neighborhood. We measure the grade, account for the swing arc, and build so the gate clears cleanly every time. Steel, treated lumber, aluminum, or a hybrid frame. We’ll show you what makes sense for your specific driveway, and quote it before we start.

Pedestrian Gate
A pedestrian gate off Shoreline Highway or one of the side streets off Tennessee Valley Road sees the same daily fog as every other gate in the valley. We build these with materials that hold up to moisture: galvanized post ties, stainless hinge hardware, and wood that won’t swell itself off its hinges in the first season. Small gate, same standard.

Sliding Gate
Sliding gates work well on tight Tamalpais Valley driveways where there isn’t enough room for a full swing arc. The track matters more than the gate itself. We set the track on a proper base so winter runoff and hillside debris don’t shift it. If the ground moves, the gate binds. We’d rather build it right the first time than come back and dig it out after a storm.

Swing Gate
Swing gates are the most common installation in Tamalpais Valley, and also the most likely to fail when done wrong. On driveways that climb, a stock opener arm assumes level ground and the gate drifts or binds within months. We use slope-compensated arms and articulating hardware when the grade calls for it. That’s not an upgrade we upcharge; it’s just the correct way to build on the terrain here.

Trusted Brands We Service in Tamalpais Valley
We install and service gates fitted with operators from Linear, Viking, Ghost Controls, DoorKing, and others. That covers most of what’s already hanging on Tamalpais Valley driveways, and most of what we’d recommend for new installations. Because our service area includes Gate Installation in Tamalpais Valley neighborhoods from Tennessee Valley Road up to Panoramic Highway, the person who shows up knows which operator board survives fog corrosion and which one doesn’t. We also keep common replacement parts stocked for local callbacks and warranty work, so you aren’t waiting two weeks for a control board to ship from somewhere else.
Common Gate Installation Problems We See in Tamalpais Valley Homes
- Hinge posts corroding at the base. Daily marine fog settles at ground level, and the bottom of a gate post stays damp even when the rest of the driveway looks dry. Galvanized post anchors and stainless fasteners make the difference here. Painted mild steel will fail in a few years.
- Automatic swing operators binding on steep driveways. Standard opener arms assume level ground. On the gradients common along Panoramic Highway and the hillside streets above Shoreline Highway, the gate drifts and the motor strains until it burns out. Slope compensation fixes it.
- Wood gate frames swelling seasonally. The fog cycle in Tamalpais Valley means wood expands and contracts more aggressively than in Corte Madera or Mill Valley. Hinges that were aligned in summer go tight in the wet months, and the frame starts wearing itself against the latch.
- Post footings shifting after winter rain. The same runoff that feeds the Mount Tam watershed also moves soil under shallow footings. A gate post set 18 inches deep will drift. We go deeper and wider on new installs, especially on hillside lots.

FAQs - Gate Installation in Tamalpais Valley
Tamalpais Valley’s position beneath Mount Tamalpais funnels morning fog directly through the canyon, and that marine moisture sits on gate hardware hours longer than it does in Corte Madera, which gets more sun and burns off earlier. Hinges and posts corrode at the base, and even galvanized hardware will eventually go. We use stainless steel hinge posts and fasteners on new installs in Tamalpais Valley specifically because of this. If your existing gate is sagging but the panel is still solid, it’s almost always the hinge post, not the gate itself. Call (877) 610-2993 and we’ll come look at it.
Yes. Tamalpais Valley sits within a Cal Fire-designated Very High Fire Hazard Severity Zone, so any gate that blocks emergency vehicle access to a private driveway or road must include Knox-Box hardware or breakaway mechanisms that fire crews can operate. This isn’t optional, and we handle it as part of the installation, not as an upsell. The compliance retrofit is also one of the main reasons we get called out to existing gates. Give us a call at (877) 610-2993 for a free quote on bringing yours into compliance.
You can, but the solar panel needs to be sized and positioned differently than it would be on a sunny lot in Larkspur. Morning fog in Tamalpais Valley means panels get their strongest charge in the middle of the day and afternoon. We mount them for the right sun angle and run the right panel size for the operator’s draw. A panel that would keep a gate running fine on a sunny street may barely keep it above threshold here. Residual power matters. Call us for a site walk and we’ll tell you whether solar is realistic for your exact driveway, or whether hard-wired makes more sense.
Because the opener was installed with a standard arm designed for level ground, and your driveway climbs. On a slope, the gate’s swing arc changes, the motor strains, and the gate drifts or binds, usually about halfway through its travel. The fix is not to grease the hinges or tighten anything. The fix is a slope-compensated or articulating arm that matches the grade. That’s a routine call for us in Tamalpais Valley, especially on streets off Panoramic Highway. Call (877) 610-2993 and we’ll measure the grade and tell you exactly what’s needed.
For low maintenance in Tamalpais Valley’s fog-heavy microclimate, we recommend steel or aluminum for the gate frame, with stainless steel or fully galvanized hardware. Aluminum won’t rust; steel needs a proper coating but handles the heavier double-gate spans that a wood-frame hang won’t. Wood is the dominant style in this neighborhood and it can absolutely work, but you need to understand that the marine moisture here means more frequent resealing and seasonal adjustment than you’d expect in a sunnier town. We’ll tell you honestly what each material means for maintenance on your specific driveway before you spend the money.
