If your gate is dead, grinding, or reversing on its own, call (877) 610-2993 and a live person answers.

Mercer Island sits fully surrounded by Lake Washington. That is not a postcard detail. It means the air is wetter than Bellevue or Issaquah, and wet air gets into gate operator housings, corrodes circuit boards, and rusts rack hardware faster than you would expect. It also means many homes along East Mercer Way, West Mercer Way, and the shoreline lanes have long driveways with custom ornamental gates that weigh more than their operator rating. We spec for that.

When a Mercer Island gate stops working, you do not want a call center three states away. You want someone who knows the island, answers the phone, and shows up with the right parts. That is what we do. Hal Gatewood owns the company, his name is on every invoice, and the 90-Day Done Right Promise is in writing on every job we finish.

Why Gatewood Fence & Gate Is Mercer Island’s Preferred Gate Motor & Opener Company

Mercer Island homeowners tend to be specific about what they want. They have lived in places where a gate was just a gate. On this island, the gate is the first thing a guest sees, and it has to work with intercoms, cameras, and smart-home access. We get that. Our gear includes service for LiftMaster, FAAC, BFT, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule, and we carry common boards, limit switches, and remotes so we are not ordering parts and making you wait a week.

We also stand behind the work differently than most. Every job, from a simple sensor realignment to a full motor replacement on an ornamental slide gate, gets the 90-Day Done Right Promise. If it is not right, one call brings us back. That is not a caveat. It is a handwritten line on the invoice.

Our Gate Motor & Opener Services in Mercer Island

The work we do across Mercer Island covers everything from repairing a 1970s swing operator to installing a new motor on a custom slide gate built last year. Here is how each service lands on the island.

Motor Repair

Most of what we fix on Mercer Island is operator failure from moisture intrusion, stripped gears from overweight gates, or limit switches that have given up. When a motor burns out on a lakefront property near East Mercer Way, it is often because the gate was heavy, the post shifted over a wet winter, and the operator was working against itself. We diagnose the whole assembly, not just the motor. That means checking the hinge post, the chain or rack, the photocell loops, and the control board before we quote a repair. Pricing for common motor repairs in Mercer Island runs $285-$640, with the quote agreed before we turn a wrench.

Motor Installation

A new motor on Mercer Island usually means matching an operator to a custom gate that weighs more than a catalog spec sheet would assume. We measure the gate, look at the hinge post, and pick an operator that will not be running at redline every cycle. Installation on a swing gate typically runs $1,200-$2,800 depending on whether we are reusing existing brackets and wiring or starting fresh. We do free measures and written quotes, and we never surprise you with a number at the door.

Linear Motor

Linear and rack-drive slide motors are common on Mercer Island’s newer properties because they are quiet and clean-looking, and they hide well in a modern custom build. The downside here is humidity. The rack sits low, near the ground, and exposed linear track hardware rusts faster than you would think. Linear motor repair in Mercer Island typically runs $350-$750 for common failures like limit switch replacement, gear rebuilds, and board swaps. We use sealed operators and marine-grade stainless hardware on replacements so the next repair is years away, not months.

Slide Motor

A heavy slide gate on a long driveway north of the town center needs a motor that can handle the mass without stripping. Slide motor service in Mercer Island covers everything from a Viking or DoorKing replacement to a full repositioning when the track has settled. Slide motor installation runs $1,400-$3,200 for most island properties, depending on gate weight and access. If your slide gate is grinding or halting mid-travel, call us before it burns the motor out completely. That repair is cheaper than the replacement.

Trusted Brands We Service in Mercer Island

We are certified to service nine major gate brands, and the ones we see most often on Mercer Island are LiftMaster, FAAC, Viking, and DoorKing. We also work on Ghost Controls and Elite systems on a regular basis, especially on the mid-century ramblers where a homeowner upgraded the operator but kept the original iron gate. Because we stock common boards, remotes, and limit switches, we can often complete same-week repairs on Mercer Island without waiting on freight from a distributor.

Common Gate Motor & Opener Problems We See in Mercer Island Homes

• Corroded circuit boards and limit switches. The island’s persistent lake humidity degrades electronics inside operator housings faster than in Bellevue. We open the housing and check for green corrosion on the board before assuming the motor is dead.
• Post footings shifted by wet winters. Long driveways with heavy gates settle over time. When the hinge post moves even a fraction of an inch, the auto-close alignment goes out of spec and the motor works against itself until the limit switch or gear fails.
• Overweight custom gates on under-rated operators. Ornate wrought-iron or powder-coated steel gates on new builds often weigh more than the operator’s rating. Stripped gears and burnt motors happen when the safety loops are not tuned for the extra mass.
• Rust on exposed rack and pinion hardware. On slide gates, the rack sits low and catches moisture from wet ground and lake air. Once pitting starts, the motor strains and the gears wear fast. Marine-grade stainless replacement parts stop that cycle.
