AfterFast, Reliable Gate Installation Across Kenmore
A new driveway or pedestrian gate on a Kenmore home typically runs $2,400-$7,800 installed, with most sliding gates landing between $3,200 and $5,600 depending on length, material, and whether you’re adding automation. That covers the post footings, the gate itself, the operator if you want one, and the labor to hang and adjust everything so it swings or slides square the day we leave. We’ve been doing Gate Installation work in the Kenmore area long enough to know that what works in a dry hillside lot in Bothell does not hold up on a low, saturated lot near the Sammamish River mouth. The soil moves, the wind pushes, and the posts that were perfectly plumb in July are leaning by February if the footing wasn’t built for it. We plan for that before we ever dig a hole. Call us at (940) 412-7340 and we’ll talk through what your property actually needs.
Why Portcullis Gate Repair Is Kenmore’s Preferred Gate Installation Company
People in Kenmore mostly find us after someone else’s gate failed. A carpenter friend set a post in a bag of fast-setting concrete and two winters later the gate drags on the ground. Or a handyman hung a heavy wrought-iron gate on hinges meant for a kitchen cabinet door and it pulled out of the cedar frame by spring. We hear that story weekly in the neighborhoods between Arrowhead and Moorlands. Our answer is the same one every time: the post footing governs everything, and the footing has to be engineered for what Kenmore’s ground actually does.
Dean Prescott, our owner, started Portcullis in 2008 with a rule that hasn’t changed: every customer gets the price in writing before we turn a single bolt. Every repair and installation carries a written Kingswell Guarantee. If it fails inside 365 days, the return visit is free. That’s the 365-Day Done Right Promise. Every crew member is background-checked and arrives in uniform, and a live person answers our phone at 2 a.m. when a gate quits during a windstorm and you can’t get your car out. You can reach us any hour at (940) 412-7340.
Sliding Gate Installation in Kenmore
Sliding gate installation in Kenmore is the option we recommend most for waterfront and near-lake properties, because a slide gate hangs from nothing and doesn’t rely on a post staying perfectly plumb to stay level. A cantilever slide gate rides on rollers mounted to a concrete pad, so when the ground shifts – and in Kenmore it shifts – the gate isn’t pulled out of alignment the way a swing gate is. Most residential sliding gates in the city run $3,200-$5,600 installed, depending on the track system, the gate material, and whether we’re adding an operator. A heavier steel or aluminum gate over 14 feet on a double-track system will land at the top of that range.
Track, Rollers, and the Concrete Pad
The part of a sliding gate that fails in this climate is rarely the gate itself. It’s the concrete pad the track bolts to or the rollers that carry the weight. On low lots near the Lake Washington shoreline, we pour a deeper pad with more embedded steel than a standard spec, because saturated soil compresses under repeated load. Galvanized or stainless rollers against a stainless track keep corrosion from the lake-effect humidity from freezing the gate in place. We price that work upfront, in writing, before we order materials.
Slide Gate Automation
If the gate will open and close on its own, the operator matters as much as the steel. Most Kenmore slide gates we build use a rack-and-pinion drive with a magnetic or mechanical limit switch, not a chain drive that stretches in damp air and throws the gate out of sync. We calibrate the limits, set the force sensitivity, and walk you through the manual release before we mark it done. When the power drops during a November wind event, you need to know how to get your car through without a service call.
Gate Opener Installation in Kenmore
Gate opener installation in Kenmore means pairing the right operator with a gate that will see constant damp, occasional lake wind, and whatever the soil under the posts decides to do this year. A quality residential swing-gate actuator with installation typically runs $1,100-$2,400 on a Kenmore property. A slide-gate operator with installation runs $1,600-$3,200. Both ranges cover the operator itself, the mounting hardware, the safety sensors, the wiring run, and the programming so your remotes and keypad work before our truck leaves the driveway.
Actuator Choice: What Actually Lasts Here
The actuator is the motorized arm that physically pushes a swing gate open and pulls it shut. In coastal-humidity air, a low-grade actuator will work for a season and then the internal limit switches corrode. We stock and install Linear and Viking operators for most Kenmore swing gates, with Ghost Controls as a solid choice for gates under 16 feet. If the gate faces the lake and catches direct wind, we step up to a heavier-duty model with an oversized capacitor for cold morning starts.
Safety Sensors, Every Time
Washington requires automatic gates on residential property to stop and reverse on obstruction, and we’d install sensors regardless of what the code said. On a Kenmore yard where kids ride bikes near the Burke-Gilman Trail side of the lot, a photocell or edge sensor is the difference between a gate that politely reverses and one that crushes a bicycle frame. We test the obstruction response with an actual object during the install, not just a bypass. We’ll show you the test too.
Trusted Brands We Service in Kenmore
We train our technicians on nine major gate-operator brands, and for Kenmore work we see mostly LiftMaster, Linear, Viking, and Ghost Controls on the residential side, with DoorKing and BFT on commercial entrances. Because the crews that serve this city are the same ones who service the wider King County corridor, we stock common linear arms, control boards, and safety sensors on the truck rather than making you wait a week for a part that has to be ordered from a distributor. If your gate opens with a Linear keypad or a Ghost Controls remote and we’re rebuilding the gate, we can usually keep the automation you already own and integrate it into the new frame. Fewer new parts, clearer invoice.
Common Gate Installation Problems We See in Kenmore Homes
- Leaning posts from saturated ground. We see this constantly on lots near the Sammamish River mouth and along the north Lake Washington shore. The footing shifts, the post tilts, and the gate sags until it drags on the ground or the latch stops catching. The fix is a deeper or wider footing and a re-hang, not just a hardware adjustment.
- Cedar swing gates rotting at the joints. Kenmore’s lake-effect humidity keeps the mortise and tenon joints of older cedar gates damp for months after the rain stops. The frame twists, fasteners tear out, and the gate takes on a permanent diagonal. We can re-frame or replace and often save the existing panels if the wood isn’t past saving.
- Burke-Gilman Trail gate impacts. Homeowners close to the trail catch cycling traffic along their fence line. Bent strike plates, blown-out latch receivers, and misaligned frames become a spring ritual. A heavier latch plate and a steel frame corner are cheap insurance compared to the fourth callout in two years.
- Wind load on solid infill gates. A solid cedar or composite gate panel acts like a sail in a Lake Washington storm. If the hinge posts are undersized or the hinge spacing wasn’t calculated for the panel area, the wind torques the post every time it blows and the gate binds against the latch. That’s why wind load is part of every Kenmore quote we write.
Pricing for Gate Installation in Kenmore, WA
Here are the numbers we quoted on recent jobs in the city, so you have a real reference point. A standard 4-foot pedestrian gate in treated cedar with a galvanized post and concrete footing: $800-$1,400. A 10-foot driveway swing gate in aluminum with one actuator and sensors: $2,900-$4,800. A 14-foot cantilever slide gate in steel or aluminum with a rack-drive operator: $3,800-$5,600. A double swing gate with two actuators, coordinated openers, and a keypad: $5,200-$7,800. Every one of those prices was written down before we started. We do not quote one number in the driveway and another after the gate is in pieces. The Kingswell Guarantee says the price you approve is the price you pay.

FAQs About Gate Installation in Kenmore
Kenmore’s low-lying soils near Lake Washington and the Sammamish River stay saturated most of the year, which means standard post footings set at standard depths will sink and heave within a few seasons. We size the footing to the post, the gate weight, the wind load, and the specific soil condition on the lot, and we pour deeper or wider bases than code minimums on shoreline properties. It costs a bit more in concrete and labor, and it’s the difference between a gate that still hangs square in five years and one that drags on the ground by spring. Call (940) 412-7340 and we’ll explain what your soil actually needs.
Most operators have a manual release – a keyed lock or a pull handle on the side of the motor housing – that disconnects the gate from the drive gear so you can push it open by hand. On a slide gate, release the motor and push the gate along the track. On a swing gate, release the actuator and push the gate leaf open. Then check your breaker before assuming the gate is dead. If the gate still won’t move after the power returns, don’t force it until the operator’s clutch has re-engaged; call us at (940) 412-7340 and a live person will answer no matter the hour.
The Burke-Gilman Trail runs directly through Kenmore, and gates along the corridor take repeated incidental hits from cyclists and foot traffic – bent strike plates, blown-out latch receivers, and misaligned frames. A gate that’s bumped three times a week will loosen its hardware fast, no matter how well it was hung. We build trail-side gates with heavier latch plates, stronger frame corners, and closer hinge spacing than a gate on a quiet cul-de-sac, and we still recommend an annual hardware tightening for those properties. It’s a three-minute check that prevents most of the spring repair calls we get.
Kenmore sits at the north end of Lake Washington, and the wind sweeping south across the lake hits shoreline properties head-on. A solid infill gate panel acts like a sail; every gust torques the hinge posts and pulls apart the frame. We calculate wind load when we size the posts and choose the hinges, and we’ll often spec a partially open or slatted design for a lake-facing gate so the wind has somewhere to pass through. If you’re adding an operator, the gate’s wind profile also affects the actuator size. You don’t want an undersized motor fighting a 40 mph gust.
Yes. A powered gate without a functioning reversing sensor is a crushing hazard for any person or animal in its path, and Washington requires obstruction protection on residential automatic gates. We install photocells at the gate opening and, on heavier gates, a contact edge strip along the leading edge that reverses the gate the instant it meets resistance. We test the sensor on every install and show you where the manual release is before we leave. A gate operator without a working safety edge is not a minor omission; it’s a liability and it’s dangerous.
