Fast, Reliable Gate Installation Across Demarest
Gate installation in Demarest runs from about $1,800 for a basic single swing gate to $9,500+ for an automated sliding gate with custom steel work and underground operator wiring. Most Demarest driveways need a measured site visit before we quote, because slope, setback, and shared property lines change what will actually fit and what the borough will permit. We schedule Demarest estimates within 48 hours, usually faster. Call (877) 610-2993 and you’ll reach a live person, not a voicemail tree.
Demarest is not a town where you can bolt a gate to any post and call it done. Short frontages off Hardenburgh Avenue, private lanes with shared driveways, and mature tree roots under poured footings all shape the job before we touch a single hinge. Hal Gatewood has been doing this since 2001, and the person who measures your gate is the same person who stands behind the finished work.
Why Gatewood Fence & Gate Is Demarest’s Preferred Gate Installation Company
We have walked enough Demarest properties to know what’s actually under the ground. When a gate post leans on Knickerbocker Road, it’s usually not a bad hinge. It’s a Norway maple root that spent two decades pushing against the concrete collar. When a swing gate drags on an uphill driveway off Brookside Avenue, the panel is usually straight and the post has racked out of plumb from freeze-thaw heave. Those are the jobs we fix correctly, because we look at the footing before we look at the hardware.
Our work in Demarest carries the 90-Day Done Right Promise in writing. If a gate binds, a post moves, or an operator acts up within 90 days of install, one call brings Hal back. No runaround, no “that’s normal settling.” We also offer a free second opinion on any written estimate, so if another company quoted you for a full gate replacement and you’re not sure you need it, bring us the paperwork. We’ll tell you straight.
Every call to (877) 610-2993 is answered by a person, 24 hours a day. Not a call center in another state. Not a chatbot. Hal’s name is on the shop and on every invoice, and his crew of background-checked, uniformed technicians shows up when the schedule says they will.
Our Gate Installation Services in Demarest
Driveway Gate Installation
Most Demarest homes sit on lots wider than the Bergen County average, which means driveway gates here tend to be wide enough for two cars or a car and a delivery truck. We install steel, aluminum, and ornamental iron driveway gates sized to your actual opening, with operators matched to gate weight and daily cycle count. If your driveway crosses a shared property line, we handle the survey coordination and neighbor agreements that Demarest’s zoning permit process requires before the first post hole is dug.

Sliding Gate Installation
On Demarest side streets and short frontages, a swing gate often will not work because there is not enough setback room for the panel to arc over the sidewalk or road edge. A sliding gate rides on a track or cantilever rail and needs no swing clearance at all. We install rack and pinion slide gates, chain-driven slide gates, and cantilever systems, and we handle the underground power run, safety photo eyes, and operator programming as part of the job. This is one of our most requested installations in Demarest, specifically because of how many driveways here are tight to the property line.

Swing Gate Installation
A swing gate on a Demarest property with generous landscaping is a classic look, especially ornamental steel matching existing fence lines. But swing gates put more stress on hinge posts than slides do, and on Demarest’s clay-loam soil with freeze-thaw cycles, the post footings have to be deep and properly set or the gate is binding within three winters. We excavate deeper footings than code minimums and use root barriers where mature oaks or maples are nearby, then mount the hinges and set the operator so the gate does not fight the post.

Pedestrian Gate Installation
We also build and install pedestrian gates beside driveways, matching the driveway gate in style and hardware. On shared driveways where two homes use one entrance, a pedestrian gate keeps foot traffic separate and protects the automated driveway gate from unnecessary cycles. We can add keypads, intercoms, or card readers so both households have controlled access without sharing a remote.

Trusted Brands We Service in Demarest
Gatewood Fence & Gate is certified to service and install nine major gate brands, including Linear, Viking, and DoorKing. We know the control boards, limit settings, and common failure points on each one, which means faster installs and fewer callbacks. For Demarest customers, we keep common operator parts and safety edges stocked locally, so a replacement control board or a failed photo eye does not mean a week of waiting on a freight shipment. If your existing gate has a brand we service and you are replacing it, we can often reuse working components and save you real money without cutting corners.
Common Gate Installation Problems We See in Demarest Homes
- Shared driveway posts shifting on the property line. When one neighbor’s mature oak pushes roots against a shared post footing, the entire post can lean and bind the operator. The fix starts with the footing, not the hinge.
- Swing gates binding against the street edge during freeze-thaw heave. Demarest’s January and February hard freezes cause the clay-loam soil to heave, tilting hinge posts outward. The panel itself is usually straight; the post is what moved.
- Intermittent loop detector failures on long driveways. Road salt leaches into the clay soil and corrodes the wire splices near the operator, so the gate sometimes opens on approach and sometimes does not. We replace the loop and seal the splices properly.
- Root-cracked concrete collars on brick gate pillars. On tree-lined lanes, Norway maple roots lift the concrete collar around a brick pillar and the pillar leans inward. Replacing hinges won’t hold. The footing has to be re-poured first, then the pillar reset, then the hardware.

FAQs - Gate Installation in Demarest
We do not install a new gate on a shared property line without first confirming the property boundary and getting written agreement from both owners. Demarest’s zoning permit process requires it for any fence or gate over 4 feet high, and many private lanes in Demarest have shared driveways where the post physically sits on the line. We coordinate the survey, handle the neighbor conversation if you want us to, and set the post so it works for both sides. On a tree-lined lane off Hardenburgh Avenue, we reset a shared driveway pillar this way after a Norway maple root cracked the concrete collar. The original 1990s swing gate had dragged on the asphalt for over a year, but the actual fix was a new 18-inch footing with a root barrier, not a new gate. Call (877) 610-2993 and we’ll walk you through what your specific shared driveway needs.
Yes, and this is the most common reason Demarest homeowners choose sliding gates. A slide gate needs no arc clearance, so it works on short frontages where a swing panel would hit the sidewalk, the road, or a neighbor’s fence. We install rack and pinion slide gates with the track set flush or raised depending on your winter plowing situation, and we handle the operator, safety edges, and photo eyes as one job. If you have a slope, we’ll spec a cantilever slide so the gate rides above the ground and never drags through snow or ice.
Usually you need new footings, not just new hinges. Leaning posts on a 25-year-old Demarest gate usually mean the concrete footing below grade has cracked or shifted from frost heave or root pressure. Hinges replaced on a leaning post will just bind again. We dig down, inspect the footing, and tell you plainly whether we can re-set the existing post or need to pour a deeper one. On Demarest’s wooded lots we also add a root barrier when mature oaks are close enough to keep pushing. The panel itself is often worth keeping, and we’ll tell you that too.
Yes. For any Demarest install where the driveway serves one or two homes and has to stay drivable, we schedule the work in phases so the opening is never blocked overnight. On shared driveway jobs we keep a temporary pedestrian gate operating while the vehicle gate is out, and we time concrete pours so the driveway is usable the same day. If we’re replacing an automated gate, we remove the old operator last and install the new one first, so you are never left with a gate stuck open or closed.
In most cases, yes. Demarest’s municipal code requires a zoning permit for any fence or gate over 4 feet high, and a replacement gate that changes the footprint, post placement, or operator type often triggers the same review as a new install. We handle the permit paperwork as part of the job, including any survey or neighbor agreement needed for a shared driveway. If you are not sure whether your replacement triggers a permit, call (877) 610-2993 and we’ll tell you what Demarest will require before you spend a dollar.
