Fast, Reliable Gate Installation Across Cohasset
A new gate installation in Cohasset typically runs $3,200-$8,500 for most residential properties, with custom ornamental iron work on waterfront estates reaching $12,000-$18,000. Most Cohasset homeowners choose automated swing or double gates for their driveway, and our crew can usually complete the full installation in one to two days once materials arrive. If you’re weighing repair against replacement on an older gate, call us at (833) 754-7503 and we’ll walk through the numbers with you.
We’ve been driving out to Cohasset since 1984, and we know the difference between a straightforward post-and-panel job and the kind of custom fabrication this town actually demands. The salt air off Massachusetts Bay, the shallow granite ledge that stops a post hole at 14 inches, the frost-heaved pillars on Jerusalem Road - these aren’t surprises to us anymore. They’re the conditions we plan for before we load the truck in the morning. Our Gate Installation team serves the full 02025 zip code, from the harbor-front estates to the inland Colonials near Route 3A.
Why Ironworks Gate Co. Is Cohasset’s Preferred Gate Installation Company
Cohasset homeowners don’t call us for quick fixes on catalog gates. They call because their 1890s wrought-iron driveway gate has sagged on its granite pillars for the third spring in a row, or because the automated operator they had installed five years ago has seized from salt corrosion and the original installer is out of business. We’ve built our reputation here on showing up, understanding what we’re looking at, and doing the work so it lasts.
Our reviews from Cohasset customers consistently mention the same things: we answer the phone, we show up when we say we will, and we don’t disappear when something needs adjusting. That matters in a town where the same families have owned the same properties for generations and they remember every contractor who let them down.
Response time to Cohasset is typically same-day or next-day for standard consultations, and we keep our scheduling tight because most of our work here requires a second look before we can quote accurately. A gate on shallow ledge needs probing. A historic iron gate needs measuring for custom hardware. We don’t guess over the phone.
The local knowledge that builds trust here is simple: we know Cohasset’s building inspector expects permits for automated gates with vehicular access to public roads. We know the harbor-front properties need stainless steel or marine-grade hardware, not standard galvanized. And we know that a gate post on ledge can’t be solved with a longer auger bit - it needs a different engineering approach entirely.
Our Gate Installation Services in Cohasset
Swing Gate Installation
Swing gates remain the most common request we get in Cohasset, and for good reason. They suit the town’s estate-scale properties and they pair naturally with the existing granite pillar posts that define so many Cohasset driveways. We install both single and double swing configurations, automated with operators sized to the gate weight and wind load. On waterfront properties, we specify FAAC or BFT hydraulic operators with marine-grade hardware packages - the salt air will destroy a standard residential operator in two seasons.
The challenge with swing gates here is alignment. Frost heave shifts pillars. Shallow ledge prevents deep footings. We address both during installation, not after the gate starts dragging.

Double Gate Installation
Double gates - two leaves meeting in the center - are the classic choice for wide Cohasset driveways, particularly on the larger harbor-front and inland estate properties. These require precise synchronization of two operators and a center latch that can tolerate seasonal movement. We recently installed a pair of custom wrought-iron double swing gates on a waterfront estate on Jerusalem Road, where the existing granite pillars had shifted from frost heave. Our crew had to core-drill through ledge for the hinge posts and used surface-mount anchor plates for the operator posts, fitting a FAAC 412 hydraulic swing gate operator to automate the 14-foot gates.
That job took two days. The gate still closes square three years later.

Driveway Gate Installation
Driveway gates in Cohasset are rarely afterthoughts. They’re statement pieces, security barriers, and weatherproofed machines all at once. We fabricate and install driveway gates in steel, aluminum, and ornamental iron, with automation packages from basic remote-open to full access control with keypads, telephone entry, and loop detectors. Every driveway gate we install in Cohasset gets stainless steel hinges and hardware as standard - the upgrade pays for itself in avoided corrosion callbacks.
We also handle the electrical trenching and low-voltage wiring for automation, coordinated with your electrician or ours.

Sliding Gate Installation
Sliding gates make sense for Cohasset properties with steep driveways, limited swing clearance, or tight setbacks where a swing leaf would encroach on the road or landscaping. We install cantilever and tracked sliding systems, with operators from Linear and Viking rated for coastal conditions. The track or cantilever frame needs a level, stable foundation - which means we probe for ledge before we quote, every time. A sliding gate on a frost-heaved track is a doorstop by March.

Pedestrian Gate Installation
Pedestrian gates - side-yard entries, garden gates, pool enclosures - are often the most detail-sensitive work we do in Cohasset. These match existing ironwork, fit irregular openings in stone walls, and need hardware that can be operated with gloved hands in January. We fabricate custom pedestrian gates to match documented historic patterns or existing estate ironwork, with automated latch releases where needed.

Trusted Brands We Service in Cohasset
We are trained and equipped on nine gate-automation brands - LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule - and we stock common parts for FAAC, BFT, and Linear locally. That means when a Cohasset homeowner calls with a failed operator, we can often diagnose and repair on the first visit rather than ordering parts and scheduling a return trip. For new installations, we specify the brand and model based on the gate weight, cycle frequency, and exposure to salt air - not on what we have in the warehouse. A harbor-front estate in Cohasset gets different hardware than an inland Colonial. We make that distinction because we know the cost of getting it wrong.
Common Gate Installation Problems We See in Cohasset Homes
- Salt air corrosion seizes hinges and operators within two to three seasons. Massachusetts Bay’s persistent onshore winds carry salt that oxidizes standard steel hardware rapidly. We see this every spring on gates installed by out-of-town contractors who specified galvanized rather than stainless or marine-grade components. The fix is never cheap - it usually means replacing the operator, hinges, and sometimes the gate frame itself.
- Frost heave and shallow granite ledge shift gate pillars out of plumb. Cohasset’s freeze-thaw cycles penetrate beneath post footings, and where ledge prevents deep anchoring, the frost action is concentrated. A pillar that was plumb in October is binding its gate by April. We address this with deeper probing, surface-mount anchor plates where ledge is shallow, and hinge designs that tolerate minor seasonal movement.
- Custom non-standard gate sizes from historic homes make off-the-shelf components unusable. Cohasset’s late-1800s and early-1900s estates were built before standard gate widths existed. A 14-foot-3-inch opening with hand-forged scrollwork can’t accept a catalog gate. We measure, fabricate, and fit on-site - often welding custom hinge brackets and latch hardware to match the original ironwork pattern.
- Granite ledge appears within 12-18 inches of the surface, preventing standard post footings. This is the defining condition of Cohasset gate work. A contractor who digs to 36 inches and hits solid granite has a problem. We probe first, quote accordingly, and come prepared with core-drilling equipment or surface-mount anchor plates. The alternative - a post that rocks in its shallow hole - is a callback waiting to happen.

FAQs - Gate Installation in Cohasset
Yes, Cohasset requires a building permit for any automated gate with vehicular access to a public way, and the installation must comply with the Massachusetts State Building Code and any applicable zoning setbacks. We pull permits as part of our standard process and coordinate the inspection schedule so you don’t have to manage the paperwork. Call (833) 754-7503 and we’ll confirm whether your specific property requires additional approvals.
Hydraulic swing gate operators from FAAC or BFT perform best in Cohasset’s coastal conditions because they tolerate pillar movement better than electromechanical units and their sealed hydraulic systems resist salt corrosion. For properties with severe ledge constraints, we often use surface-mounted operator posts independent of the gate pillars, so frost heave doesn’t affect operator alignment. We’ll assess your specific ledge conditions during the free estimate and recommend the right unit for your gate weight and exposure.
We specify stainless steel or marine-grade hardware for every Cohasset installation, apply epoxy primers and marine-grade powder coating to fabricated steel components, and use sealed hydraulic operators rather than exposed electromechanical screw or belt drives. We also recommend an annual $89 Seasonal Tune-Up to inspect hinges, lubricate moving parts, and catch surface oxidation before it penetrates - a small cost compared to replacing a seized operator. The 90-Day Done Right Promise covers any corrosion-related adjustment in the first three months.
Yes, we fabricate custom gates to match documented historic patterns or existing estate ironwork, using forged scrolls, twisted pickets, and hand-finished details that replicate the original blacksmith work. We photograph and measure your existing gate, produce shop drawings for your approval, and weld on-site to fit the irregular openings typical of Cohasset’s stone walls and granite pillars. The result is a gate that looks like it was always there - because in craft terms, it was.
We core-drill through the ledge for anchor bolts or use heavy-duty surface-mount anchor plates bolted to the exposed stone, depending on the gate load and available surface area. This is standard practice for us in Cohasset - we probe for ledge before we quote, and we bring the right equipment to handle it. A post that can’t go deeper can still be rock-solid if it’s engineered correctly. Call (833) 754-7503 for a free site evaluation and we’ll show you exactly how we’d anchor your specific posts.
