AfterGate Repair in Redwood City, CA
Gate repair in Redwood City usually comes down to one of three problems: a hinge post that has rotted or corroded at the base, a weld seam that has cracked on a steel frame, or an opener that has lost its limit settings and doesn’t know where to stop. Most jobs we see are fixed the same day in your driveway, and the price is written down and agreed before we touch anything. If your gate groans, sags at the latch side, or the motor runs but the gate doesn’t move, call (877) 610-2993 and describe what you’re hearing. We’ll give you a straight answer about whether it’s a repair or a replacement.
Why Redwood City Homes Are Different
Redwood City splits into two very different worlds when it comes to gate work. The Redwood Shores neighborhood in the 94065 ZIP sits on former San Francisco Bay salt evaporation ponds, and the salt-laden wind that blows off the bay oxidizes ferrous gate hardware and attacks weld seams on steel frames from the inside out. A gate in Redwood Shores can look perfectly fine on the outside while the post corrodes at the base where concrete meets marine soil. Two miles west in Farm Hill or Edgewood, that same failure mode is rare. The drier, milder weather there keeps hardware in much better shape.
Housing stock shapes the work too. Central and east Redwood City, in the 94061 and 94063 ZIPs, has a lot of 1940s through 1960s tract homes with original wrought-iron or wood side gates on aging concrete posts. Those posts wick winter moisture and rot from the ground up. The 94062 corridor bordering Woodside transitions to larger ranches and custom homes, many with automated driveway gates. Redwood Shores is 1980s to 2000s planned-community construction with standardized gate styles tied to strict HOA specifications. Nearly all of it requires architectural committee approval before any visible gate work begins, which adds a layer of paperwork that neighboring San Carlos or Menlo Park rarely imposes.
Gate Repair in Redwood City
Gate repair in Redwood City typically costs $180 to $420 for hinge work, $150 to $350 for rail repair, and $450 to $1,200 when a post has to be reset or replaced. The most common call we get is a gate that sags or scrapes, and almost always the problem is in the post, not the panel. Fix the post and the gate swings clean for years. Fix only the panel and you’ll be back in the same spot within a season. We do the welding on site so the gate never leaves your driveway, and we stand behind the work with the 90-Day Done Right Promise in writing. For the full scope of what Gate Repair covers, we publish pricing and job notes on the service page.
Hinge Replacement
In the older central neighborhoods of Redwood City, a lot of original iron gates from the 1950s and 1960s still hang on hinges that have been opening and closing for sixty years. The pin wears, the barrel ovalizes, and the gate drops just enough to drag. Hinge replacement in Redwood City runs $180 to $420 depending on whether it’s one hinge or a full pair and whether the post needs shimming.
Post Reset or Replacement
Redwood Shores has a failure mode we rarely see anywhere else in the city. The steel inside the concrete footing rusts through from salt-saturated soil, so the post looks straight until you push on it, then it leans and the gate stops opening. Post replacement runs $250 to $650 on a typical job, and we set the new post in a deeper footing with a waterproof barrier so the salt doesn’t start eating it from day one.
Weld and Rail Repair
Steel tube gates fail at the weld seams, and in Redwood City the bay wind gets inside the frame tubes and eats the metal from the inside out. By the time you see a crack on the surface, the seam has been failing for a while. A rail or seam weld repair usually runs $150 to $350 and keeps a gate that a replacement-hungry company would have you throw away.
How much does gate repair cost in Redwood City?
Most gate repairs in Redwood City run between $150 and $650 depending on the job. Hinge work lands at $180 to $420, rail welds at $150 to $350, and post replacement at $250 to $650. We quote the full price before any work starts. Call (877) 610-2993 for an exact number.
Can you fix my gate the same day in Redwood City?
In most cases, yes. If you call before noon we can usually have someone out the same day, and we keep common hinge hardware, weld plate, and operator parts on the truck so the fix happens in one visit. Salt-corrosion jobs in Redwood Shores sometimes need a follow-up if a post has to be set and cured.
Gate Installation in Redwood City
Gate installation in Redwood City runs from about $500 for a pedestrian side gate to $15,000 for a full security gate system with access control. Most single driveway gates land between $1,800 and $4,500, and a double swing gate with automation starts around $4,500. What moves the price here is width, material, and whether the existing post is worth saving. In 94061 and 94063 the post is usually the problem. In Redwood Shores, the HOA spec is the problem. We handle the approval paperwork for you. Get the full breakdown on the Gate Installation service page.
Single Swing Gate Installation
Swing gates are the most common gate we hang in Redwood City, especially in the older central neighborhoods where the original driveway openings are still there from the 1940s and 1950s. A new single swing gate typically runs $1,800 to $4,200 installed. On larger properties in the 94062 corridor toward Woodside, double swing gates run $4,500 to $8,900 with automation included.
Sliding and Security Gate Installation
Sliding gates make sense where a swing gate would block the driveway or the grade slopes too much for a clean arc. We see that most often on commercial properties along Veterans Boulevard and on newer custom homes in the hills. A single sliding gate in Redwood City runs $3,200 to $7,500. For a basic security gate with keypad entry, expect to start around $2,800, with full systems running $7,000 to $15,000 depending on intercom, camera integration, and crash-rated posts.
Pedestrian Gate Installation
Side yard gates are the ones people forget about until the latch stops closing or the top hinge tears out of the post. Redwood City homes built in the 1940s through 1960s have a lot of original wrought-iron pedestrian gates on aging concrete posts. A replacement pedestrian gate runs $500 to $1,500 installed, including a new post if the existing one is cracked or spalling. We also build wood plank gates to match older fence lines.
Why do gate posts fail faster in Redwood Shores than in central Redwood City?
Redwood Shores sits on former salt evaporation ponds, and that salt remains in the soil. Moisture and salt wick up into the concrete footing and corrode the post from the base. Central Redwood City has drier, more stable soil, so posts there fail from age and mechanical wear, not salt attack. On Redwood Shores jobs we use deeper footings, galvanized posts, and sealed bases.
Can I retrofit a 1960s swinging gate with a modern operator instead of replacing the whole gate?
Sometimes. If the panel is straight and the hinge post is solid, we can weld on modern hinge brackets and install a new LiftMaster or Viking operator with safety edges and photocells. That retrofit usually runs $1,400 to $2,800. If the post is cracking or the panel is rusted through at the seams, retrofitting just delays the inevitable.
Gate Motor & Opener in Redwood City
Gate motor repair in Redwood City typically runs $180 to $340 for common failures like bad capacitors, stripped gears, or corroded limit switches. Most diagnoses happen in under an hour, and we quote the full price before any work starts. The mix of bayfront HOA communities and older central tract homes means openers fail in very different ways depending on where you live. On Redwood Shores, salt air eats the housing and the limit switches. In the central neighborhoods, the post rots, the gate sags, and the motor burns itself out trying to drag a gate it was never sized for. The full breakdown is on the Gate Motor & Opener service page.
Motor Repair and Diagnosis
Most gate motor repairs in Redwood City are straightforward once we put a meter on the control board. Capacitor replacement runs $180 to $280, a gear assembly rebuild runs $250 to $450, and safety photocell replacement and rewiring runs $200 to $380. If your opener hums but won’t move, or opens but won’t reverse, call us and describe what you’re hearing. We’ll tell you over the phone whether it sounds like a gear, a capacitor, or a board.
Motor Replacement and Installation
A full motor replacement on a single swing gate in Redwood City runs $900 to $1,800, and a slide gate motor runs $1,400 to $2,800. New installations on a typical single-swing or slide gate run $1,100 to $2,800 depending on gate weight, power access, and whether the job is in a Redwood Shores HOA community with finish requirements. We size the operator for the gate’s actual weight and cycle frequency, not a guess from a catalog.
Battery Backup and Safety Compliance
Redwood Shores HOAs increasingly require battery backup on shared entry gates, and it’s a smart add-on anywhere in the city where a power outage leaves a driveway gate stuck. Battery backup installation runs $450 to $900 depending on operator brand and required run time. We also check every existing gate for UL 325 entrapment compliance during any motor repair. A gate installed before 2001 almost certainly does not meet current safety standards, and we’ll tell you exactly what’s missing.
Does Gatewood handle HOA approval for gate motor replacement in Redwood Shores?
Yes. Nearly all Redwood Shores gate opener work requires architectural committee approval before the motor is touched. We prepare the submittal package with the operator spec sheet, finish sample, and installation notes, and coordinate with the management office directly. That paperwork has to happen before any parts get ordered.
How do I know if my gate motor failure is actually a post footing problem?
Look at the hinge post. If the gate sags, drags, or leaves a wider gap at the top than the bottom, the post has likely rotted or corroded at the base and the motor is working harder than it should. On 1940s to 1960s Redwood City homes with original concrete-set posts, winter ground moisture rots the post from the bottom, and the motor fails trying to move gate weight it was never designed for. Fix the post first.
Gate Access Control in Redwood City
Gate access control in Redwood City means keypads, phone entry, video intercoms, and card readers that let the right people through while keeping everyone else out. The equipment is standard, but the local conditions aren’t. Redwood Shores keypads corrode from salt-laden bay air even when the exterior looks clean. Central Redwood City keypads fail because a sagging gate pulls the wiring loose at the hinge post. HOA finish requirements add another layer in Redwood Shores, where the architectural committee wants to approve mounting height, finish color, and hardware spec before installation. See the full scope on the Gate Access Control service page.
Keypad Entry
A keypad entry system in Redwood City runs $350 to $800 installed for a single-family home. In Redwood Shores, the salt air corrodes the ribbon connector inside the keypad housing, and the bottom row of buttons usually dies first. In the older central neighborhoods, the issue is more often a sagging gate that stresses the wiring at the hinge post. We fix both, and we can source marine-rated units when the HOA spec allows them.
Video Intercom and Phone Entry
Video intercoms are common on automated driveway gates in the 94062 corridor and are increasingly required by Redwood Shores HOAs when a gate gets replaced because they create an entry audit trail. A basic single-family video intercom installation runs $900 to $1,800. A single-line phone entry system runs $700 to $1,400. HOA multi-unit systems run $1,800 to $5,000 and are quoted per job.
Card Reader Systems
Card readers are common at multi-family and commercial gates along the Bridge Parkway corridor in Redwood Shores. They’re durable, but the local salt air gets into the card slot and corrodes the contact pins, causing intermittent reads. A single card reader installation in Redwood City runs $500 to $1,100 including wiring to the existing operator. We clean and reseal units when we can, and replace them when we can’t.
Does the Redwood Shores HOA have to approve a new keypad entry system?
Yes, in nearly every Redwood Shores community the architectural committee must approve the keypad’s finish, mounting height, and hardware color before installation. The management company will want the spec sheet and sometimes a photo mockup. We know the paperwork expected and can often start the approval process the same day you call. Budget a week or two for the approval itself.
Can a video intercom work with my existing LiftMaster gate operator?
Yes. We wire video intercoms into existing LiftMaster, FAAC, BFT, and Linear operators on a regular basis in Redwood City. The key is matching the intercom’s relay output to the operator’s control board input and testing the full sequence, including entrapment reversal, before we leave. Call (877) 610-2993 for a free estimate.
Gate Parts & Welding in Redwood City
Gate parts and welding in Redwood City usually means one of three things: a hinge post has rotted out, a weld seam has cracked on a steel frame, or an HOA needs the work done to an exact finish spec before a single spark gets struck. We do the welding right in your driveway so the gate never leaves your property. Hal Gatewood has been fixing these problems since 2001, and the 90-Day Done Right Promise comes with every weld. Details on the Gate Parts & Welding service page.
Hinge Replacement
Hinge replacement in Redwood City runs $180 to $420 depending on whether it’s one hinge or a full pair and whether the post needs shimming. In the 94061 and 94063 neighborhoods, original iron gates from the 1950s and 1960s hang on hinges that have been working for sixty years. The pin wears, the barrel ovalizes, and the gate drops just enough to drag on the walkway. We cut the old hinges off, weld new ones in place, and shim the gate so it swings clean.
Post Replacement
Post replacement in Redwood City typically runs $450 to $1,200 per post, and in Redwood Shores that price usually includes a deeper footing and a waterproof barrier so the new steel doesn’t start corroding from day one. Bay-fill soil holds salt and moisture, and the steel inside the concrete rusts from the bottom up while the post above ground still looks straight. By the time it leans, the footing is already gone.
Custom Welding and Rail Repair
Rail and seam repair is often the most affordable fix we do, usually $150 to $350 in Redwood City, and it keeps a gate that a replacement-hungry company would have you throw away. For custom fabrication, expect $120 to $250 per hour depending on material thickness and what’s being built, plus parts. Redwood Shores residents should know we can match the dark bronze and standardized finish specs the HOA requires.
Do I need HOA approval before welding a new gate hinge in Redwood Shores?
Yes. In nearly every Redwood Shores community you need written approval from the HOA before any visible gate modification, including a new hinge. The management company wants material, finish, and placement to match the original spec. We handle that coordination and know what the associations typically require. Call (877) 610-2993 and we’ll walk you through it.
Why does my gate post in Redwood Shores corrode from the bottom when the rest of the gate looks fine?
Redwood Shores was built on former San Francisco Bay salt evaporation ponds, and the soil is saturated with salt that works its way into the concrete footing around your post. The steel inside rusts from the base up while the visible part above the concrete looks straight. By the time the post leans, the footing is gone. This is a Redwood Shores signature failure we rarely see two miles west in Farm Hill.
Brands We Service in Redwood City

What Redwood City Customers Say
"Beautiful gate and solid work. The build took about three weeks longer than the estimate because he was waiting on the ironwork, and I would rather have known that at the start than found out along the way."
- Beatrice Nwosu"Operator had died and the manufacturer no longer makes the board. Rather than sell me a whole new system he found a compatible unit and adapted the mount. Saved me a great deal of money."
- Salvador Arredondo"Hundred and forty feet of cedar privacy fence, all posts set in concrete, all of it dead level on ground that is anything but. He walked the line with me twice before a single hole was dug."
- Judith Stallworth
