Fast, Reliable Gate Installation Across Redwood City
A new driveway gate in Redwood City typically runs $2,800 to $9,500 installed, depending on whether you need a single swing, a sliding gate, or a full automated system with safety sensors and an operator. Most installations take one to two days once materials are on hand, and we quote the exact price before any work starts. Hal Gatewood has been putting gates in the ground across the Peninsula since 2001, and we know Redwood City’s housing stock well enough to tell you up front whether your existing posts can carry a new gate or need new footings. Call (877) 610-2993 and you’ll get a live person, not a voicemail.
Why Gatewood Fence & Gate Is Redwood City’s Preferred Gate Installation Company
Hal Gatewood’s name is on the shop and on every invoice, and the shop’s address is published for anyone who wants to stop by and look him in the eye. That’s the oldest accountability there is, and it matters to homeowners in Redwood City who’ve been burned by a national outfit that quoted one number over the phone and billed another at the door. Our crew has installed swing gates off Middlefield Road, replaced sliding gate operators in Redwood Shores, and retrofitted security gates on 1940s-era side yards near Sequoia High School. We answer calls around the clock because a gate that won’t close at 10 p.m. is a problem you need handled tonight, not in the morning.
Every job carries our 90-Day Done Right Promise, written plainly on the invoice. If something isn’t right, one call brings Hal back. No fine print, no “up to” language. We also keep a $40 discount on any repair over $200, a free second opinion on any written estimate, no trip charge inside San Mateo County for scheduled work, and a permanent 10% discount for seniors and veterans. These aren’t gimmicks. They’re standing offers.
Our Gate Installation Services in Redwood City
We handle four core installation types across Redwood City: driveway gates, pedestrian gates, sliding gates, and swing gates. Each comes with its own set of local considerations, from the salt air off the bay to the older concrete posts common in central neighborhoods. Here’s how we approach each one. For more detail on the full scope of what our Gate Installation team handles, that page covers the process end to end.
Driveway Gate
Most driveway gates we install in Redwood City are automated, either a swing or a slide. In the 94062 corridor toward Woodside, we see a lot of larger-lot ranch and custom homes where the gate is the first thing a visitor sees and the first line of privacy. We size the operator to the gate’s weight and width, not to a guess. A gate that opens a hundred times a day needs a heavier-duty motor than one that opens four times, and we’d rather install the right unit the first time than come back and swap it under warranty.

Pedestrian Gate
Central and east Redwood City, the 94061 and 94063 ZIPs, are full of 1940s-to-1960s tract homes with original side gates. The gate itself may be welded steel or a wood plank panel, but the posts are usually the weak point. We pour new footings when the post is rotted or the concrete has cracked, and we hang the gate to clear the ground by half an inch so it doesn’t drag through the winter wet that soaks those older central-city lots.

Sliding Gate
Sliding gates make sense on Redwood Shores properties where a swing gate would eat half the driveway swing arc. The catch in that neighborhood is the marine air. Rack and pinion drives pit over time, and we’ve pulled sliders where the gear teeth were so worn from salt that the gate bound halfway through its travel. We install stainless hardware and sealed drive components where we can, and we explain honestly when an existing slider is better off replaced than rebuilt.

Swing Gate
Swing gates are the most common style we install in Redwood City, and they fail at the hinge post before they fail anywhere else. A gate sags in the hinge post, not in the middle, and that’s where we start. If the post is sound, we hang and balance the gate. If the post is rotted or corroded at the base, we replace the post and footing before we hang anything new. Fixing the panel without the post means fixing it twice, and we won’t do that to you.

Trusted Brands We Service in Redwood City
We’re certified to service and install operators from nine major gate brands, and for Redwood City jobs we most often work with Viking, DoorKing, and LiftMaster. Redwood Shores HOAs in particular tend to specify these brands in their design guidelines, so we keep common parts and control boards on the truck rather than ordering from a warehouse and rescheduling your install. If you already have an operator you like, we’ll match the brand. If the old one failed, we’ll tell you whether it’s worth saving.
Common Gate Installation Problems We See in Redwood City Homes
- Salt-corrosion at the post base in Redwood Shores. The 94065 ZIP sits on former bay salt ponds, and the soil is saturated with salt. We regularly find hinge posts that look fine above ground but crumble at the footing line once tested, a failure pattern you almost never see two miles west in drier neighborhoods.
- Legacy operators without proper safety sensors. Pre-UL 325 operators often lack working photocells or edge sensors. Redwood Shores HOAs are increasingly flagging these during routine inspections, which means the gate has to be brought up to current code before it’s signed off.
- Pitted rack and pinion drives on sliding gates. Years of bay wind carrying salt spray pit the gear teeth. The gate starts binding, then the motor burns out trying to push it. Replacing the rack and pinion early costs a third of what replacing the motor and drive costs later.
- Rotted wood posts in central Redwood City’s older neighborhoods. The mild ‘Climate Best by Government Test’ weather doesn’t stop winter ground moisture from rotting untreated posts. Homes built in the 1940s through 1960s often still have the original posts, and they’re overdue.
Pricing for Gate Installation in Redwood City, CA
Plain numbers. A manual single swing gate in Redwood City generally runs $2,800 to $5,500 with new posts, hinges, and hardware. An automated single swing gate runs $4,500 to $7,800, including the operator and safety sensors. A sliding gate runs $5,500 to $9,500 depending on length, automation, and whether the existing track can be salvaged. A pedestrian gate runs $1,400 to $3,200. Every estimate we give in Redwood City is a written, fixed number agreed to before any work starts. You’ll never get a call saying the price went up once the job was underway. Call (877) 610-2993 for an exact quote. Estimates are free, and seniors and veterans get 10% off for life.
These are Redwood City market prices, not national averages. Labor rates on the Peninsula run higher than the Central Valley, and Redwood Shores jobs often carry HOA-related costs for color-matched finishes or specific operator models. We’ll walk you through the line items before you sign anything.

FAQs - Gate Installation in Redwood City
It depends on the operator’s age and condition, but here’s the straight answer. Pre-UL 325 operators that cannot accept retrofitted photocells and edge sensors usually need replacement, which in Redwood City runs $1,800 to $3,400 for a new operator with sensors installed. Operators built after 2010 can often be retrofitted with non-contact sensors and an external entrapment protection board for $600 to $1,200. We’ll inspect the board and the gate’s force profile before we recommend anything, and we’ll never sell you a full replacement when a retrofit meets code. Call (877) 610-2993 and we’ll give you an honest read over the phone.
We handle HOA requirements as standard practice in Redwood Shores. That means we request the design guidelines from your HOA before quoting, match the original material and finish spec, and submit the plans for approval before any concrete gets poured. Most Redwood Shores HOAs require powder-coated steel or aluminum in a specific color and a specific operator brand, and we’ve done enough of these jobs that we can steer you through the paperwork without delays. You bring us the HOA contact, and we’ll handle the engineering details.
Because the old footing was never addressed. In Redwood Shores, the ground itself is salt-saturated bay fill, and any steel post set directly into that soil will corrode from the base up, no matter how well the above-ground portion is painted or sealed. We pour new footings with the post elevated on a galvanized base plate or set in a protective sleeve, then seal the junction so water can’t pool where the post meets the concrete. Replacing the post without fixing the footing is the most common repeat job we see in the 94065 ZIP.
Usually not. A sagging gate means the hinge post has moved, the hinges themselves are worn, or the frame has twisted. Straightening the panel without addressing the post and hinges is a temporary fix that lasts a year at best. We’ll inspect the post first. If it’s sound, we’ll rebuild the hinge assembly and re-hang the gate, which runs $400 to $900. If the post is rotted at the base, which is common on circa-1950 homes in the 94061 and 94063 areas, the post and footing replacement runs $600 to $1,400 before any panel work. Straight answers, no upsell. Call (877) 610-2993 and we’ll tell you what you actually need.
You can, but you need to pick the right hardware. Standard solar panels and openers have exposed connections that the bay air will corrode inside two or three years. We install solar operators with sealed connections and marine-rated components, and we mount the panel where it gets unobstructed exposure rather than under a tree line. A solar operator for a single swing gate in Redwood City runs $2,200 to $3,800 installed. For gates that cycle more than twenty times a day, we usually recommend going with hardwired AC instead, and we’ll explain why before you spend a dollar.
