A new driveway gate in Cos Cob typically costs between $4,800 and $18,000 installed, with custom ornamental steel and wrought-iron work on the upper end and simpler pedestrian gates starting around $2,400. Most installations take two to four days from post-setting to final operator programming, and we quote the full price in writing before the first hole is dug. Gatewood Fence & Gate has been building and setting gates since 2001, and we know exactly what the salt air off Cos Cob Harbor does to hinges, operators, and ornamental iron. Call (877) 610-2993 and you’ll get a live person, not a voicemail tree. Hal Gatewood’s name is on the shop, and the crew that measures your gate is the crew that builds it.

Why Gatewood Fence & Gate Is Cos Cob’s Preferred Gate Installation Company
We’re not a national chain that subcontracts your gate to whoever picks up the phone. Hal Gatewood founded this company in 2001 and still walks every job in Cos Cob himself, from the measure to the final swing test. Homeowners off Strickland Road, River Road, and the streets near the Mianus River know us because we show up when we say we will and we don’t quote one number on the phone and another at the door. Our published address and license number mean you can look us up, and our 90-Day Done Right Promise means one call brings us back if anything isn’t right. We answer the phone 24/7 with a live voice, not a dispatch queue.
Cos Cob is a small community. Word travels fast when a crew does sloppy work. We’ve built our reputation here on repair-first honesty and on-site welding, which means we fix gates in your driveway rather than hauling them off to a shop. That matters when you’ve got a 600-pound ornamental double swing gate at the end of a long driveway. We also carry a permanent 10% discount for seniors and veterans, and we’ll give a free second opinion on any written estimate you’ve received from another company.
Our Gate Installation Services in Cos Cob
We build and install every type of gate you’ll find along the Cos Cob shoreline and in the neighborhoods feeding into Route 1 and the Post Road corridor. Here’s what we handle daily.
Driveway Gate
Most Cos Cob driveway gates are custom steel or wrought-iron swing gates built to match the architectural character of the home. On waterfront estates we spec hot-dip galvanized posts and stainless hardware because the alternative fails within two or three seasons. Your gate gets set on frost-depth footings so the spring thaw along the Mianus River doesn’t throw it out of alignment.
Pedestrian Gate
A well-built pedestrian gate gives you daily access without opening the full driveway gate. We match the ornamental pattern to your existing panels and set the post in concrete with a stainless latch and closer. For older colonials near the harbor, we keep the proportions right so the gate doesn’t look like an afterthought bolted to a 1890s fence line.
Sliding Gate
Sliding gates make sense on Cos Cob lots where a long driveway slopes or where swing gates would block the road. Salt-laden air is hard on ground-track channels and rack-and-pinion hardware, so we use stainless track and marine-grade components. We also handle the operator, photocells, and any intercom or keypad integration you want at the property line.
Swing Gate
This is the classic Cos Cob gate: double ornamental steel panels on stone or brick pillars, often with a FAAC or LiftMaster operator tucked behind the post. The big failure point here is the hinge post. Ground heave from freeze-thaw cycles shifts the pillar, which bends the hinge and drags the gate. We set our posts below frost depth, often on helical piers near the water, so the gate swings true through January and into April.
Double Gate
Double gates carry more weight and more hardware than a single panel, and on Cos Cob’s larger estate lots they’re often the main entry point. We build paired gates with a center steel receiver post and operators sized for the full leaf weight, not the optimistic number on a catalog sheet. If there’s a security gate component, we integrate it cleanly.
Security Gate
Cos Cob homeowners on high-value lots frequently want a security gate with camera entry, a pillar-mounted intercom, and sometimes a vehicle detection loop. We install the gate, the operator, the keypad, and the wiring so everything talks to your phone. No mismatched components. No scabbed-together access system that stops working after the first nor’easter.

Trusted Brands We Service in Cos Cob
Our crews are certified to service nine major gate brands, including FAAC, BFT, Linear, and Viking. That matters because many Cos Cob homes already have an operator or access system from one of these manufacturers, and we can tie your new gate into the existing setup rather than ripping out working equipment. We keep common FAAC and LiftMaster parts stocked, so a repair or installation doesn’t stall while somebody waits on a shipping truck. If you’ve got a Linear keypad or a Viking loop detector, we know the wiring and we know what fails first near the water.
Common Gate Installation Problems We See in Cos Cob Homes
- Galvanic corrosion at hinge pins and actuator mounts. Within a few blocks of Cos Cob Harbor, salt-laden tidal air and occasional storm surge eat through standard zinc-plated hinge pins in two to three seasons. We spec stainless or hot-dip galvanized hardware on every waterfront job because we’ve pulled too many rusted pins out of gates that were installed only two years earlier.
- Freeze-thaw ground heave shifting stone and brick pillars. The tidal Mianus River shoreline makes the frost cycle worse here than in inland Greenwich. Each spring, heaving ground pushes pillars out of plumb, which throws swing gates out of alignment and bends hinge posts. Our fix starts at the footing, not the gate panel.
- Salt-driven rust on ornamental iron panels and slide gate tracks. The same harbor air that pits your gate’s decorative metal also corrodes rack-and-pinion slide gate tracks, causing noisy operation and premature wear on operator gears. Regular greasing with the right marine-grade compound extends the life, but the best fix is starting with the right materials.
- Operator failure from undersized equipment. A heavy custom double swing gate needs an operator sized for actual leaf weight, not the label on the box. We see a lot of burned-out motors on Cos Cob gates where somebody installed a residential operator on a gate that needed a heavy-duty unit.
Within a few blocks of Cos Cob Harbor, galvanic corrosion from salt-laden tidal air and occasional storm surge eats through standard zinc-plated hinge pins and actuator mounting hardware in as little as two to three seasons. That’s a failure rate far higher than inland Greenwich neighborhoods like Backcountry, because the Mianus River estuary concentrates chloride ions around gate metalwork year-round. A standard gate company page won’t tell you that. It’s why we stock stainless replacement hardware and hot-dip galvanized posts year-round, and why we’d rather over-spec a $120 hinge pin than replace a $4,000 gate panel in 30 months.
On a waterfront estate off Strickland Road, we installed a custom double swing gate with hot-dip galvanized hinge posts and a LiftMaster gate operator, after the previous zinc-plated hardware had seized from salt-driven pitting. The owner wanted matching ornamental steel panels and a pillar-mounted keypad entry. Our crew set the post footings below frost depth with helical piers to resist harbor-side ground heave, then aligned the gate so it swings silently even after spring thaw. That’s the kind of job where the spec sheet is just the starting point; the real work is knowing what the water does to steel.

FAQs - Gate Installation in Cos Cob
Properties within a few hundred yards of Cos Cob Harbor and the Mianus River shoreline sit in persistent salt-laden air that accelerates galvanic corrosion on standard zinc-plated hardware. Hinge pins and actuator mounting bolts can seize or snap within two to three seasons. We install stainless or hot-dip galvanized hardware on any job that close to tidal water. That alone often doubles or triples the service life of the gate hardware. Call (877) 610-2993 and we’ll walk your property and tell you exactly what needs replacing and why.
We set post footings below frost depth, and on harbor-adjacent or shoreline lots we often use helical piers to anchor the hinge posts against ground heave. The tidal Mianus River shoreline makes the freeze-thaw shift worse than inland lots, so a shallow concrete pour just won’t hold. Proper depth and a well-anchored post keep the gate swinging true through March mud and April thaw. If your gate is already pulling out of alignment, call (877) 610-2993 for a free estimate on a re-set.
Yes. We match the gate’s ornamental pattern to the home’s era, whether that’s a late-19th-century colonial near the harbor or a mid-century build off River Road. The intercom and camera mount goes into the pillar or post, not bolted onto the gate face. We run the wiring through conduit, not zip-tied across your hedge. The result is a security gate that reads as part of the original property. Call (877) 610-2993 and we’ll show you photos of similar work we’ve done on Cos Cob colonials.
A heavy-duty operator with a sealed motor housing and marine-grade internal components, mounted in a weather-protected post or enclosure. FAAC and LiftMaster both make units that hold up near salt water when installed correctly. We’ve pulled too many burned-out residential operators off Cos Cob gates where the motor inhaled damp harbor air for three winters. We size the operator to the full leaf weight and mount it so water drains away from the motor. Estimates are free; call (877) 610-2993.
Yes. Any automated driveway gate in Connecticut must have safety photocells and a reversing mechanism, and Cos Cob’s estates often add a vehicle detection loop for heavier gates. We install photocells as standard on every automated gate, and we test them before we leave. If you’ve got kids, dogs, or regular deliveries at the property line, this isn’t optional equipment. Call (877) 610-2993 and we’ll include the full safety package in your written quote, not as a surprise line item afterward.
