AfterFast, Reliable Gate Installation Across Alderwood Manor
Gate installation in Alderwood Manor usually runs $1,800 to $6,500 for a complete driveway gate with opener, depending on whether you’re replacing a sagging farm gate on a legacy parcel or putting in a new welded steel double gate on a mid-century ranch lot.

Hal Gatewood has run Gatewood Fence & Gate since 2001, and his name is on the shop and every invoice.

Our Gate Installation Services in Alderwood Manor
We install gates that fit the property, not a catalog. Around here that means dealing with long driveways, heavy wood panels, 40 to 60 year old posts, and the occasional agricultural remnant from Alderwood Manor’s days as a 1920s farm colony. Here’s what we handle most often:
Driveway Gate Installation
A driveway gate in Alderwood Manor has to span anything from a tight suburban pull-off on a 1970s infill lot to a wide rural entrance on a legacy parcel. We measure the actual opening, check what the posts are sitting in, and build or order the gate to match. Solar operators make sense on many of these properties, especially where running conduit to the house would mean trenching across 200 feet of root-laced soil.
Pedestrian Gate Installation
Pedestrian gates separate the front walk from the backyard or secure a side yard on a ranch home near Manor Way. We frame them square, set the posts below frost line, and hang them so they swing true a year later. In this climate, a pedestrian gate that scrapes the ground in August will bind by November, so we set clearances for wet-season soil movement.
Sliding Gate Installation
Sliding gates work well on lots where a swing gate would arc into a fence line or plantings, and they’re common on the rural edges of Alderwood Manor where driveways run long and straight. We install track and cantilever designs, die the steel so the hardware survives 38 inches of annual rain, and size the motor for the full weight of the panel, not the showroom spec.
Swing Gate Installation
Swing gates remain the standard for double driveway entrances throughout Alderwood Manor, especially on the original plat lots where two wood panels still close across the drive. We replace rotten posts, upgrade to lift-assisted operators where the gate is heavy, and add safety photocells so the panels reverse if a car or kid is in the way. For older farm gates, we often recommend Gate Installation that keeps the look but rebuilds the hardware on modern footings.

Trusted Brands We Service in Alderwood Manor
We stock and service operators from Viking, Ghost Controls, and DoorKing, along with a half-dozen other major brands. That means when a Ghost Controls board fails on a shaded Alderwood Manor driveway or a Viking arm strips out on a heavy farm gate, we can usually pull the part and have you running the same day. If a brand isn’t worth installing in this climate, we’ll tell you that before you spend the money.
Common Gate Installation Problems We See in Alderwood Manor Homes
- Rotted posts below grade. Nearly 38 inches of rain a year and constant winter humidity means wood posts in Alderwood Manor rot at the soil line, especially where red alder or Douglas fir canopy drops leaves and needles against the base. A gate sags in the hinge post, not in the middle, and that’s where we start.
- Undersized operators on wide farm gates. Legacy agricultural parcels still have 12 and 14 foot gates that were never meant to carry a motor. An undersized operator burns out in a year or two, so we size for the actual panel weight and add a lift-assist when needed.
- Missing or misaligned safety sensors. Long rural driveways need photocells and loop detectors set correctly, or the gate reverses on every delivery truck. We align sensors for the specific approach angle and grade of your driveway, not the generic template.
- Wrong permitting path. Because Alderwood Manor is unincorporated Snohomish County, owners file with Lynnwood city hall by mistake and lose weeks. We tell you exactly which county office handles your gate project before work starts.
Pricing for Gate Installation in Alderwood Manor, WA
Here’s what gate installation in Alderwood Manor actually costs. A single pedestrian gate typically runs $450 to $1,200 installed. A standard single driveway swing gate with a basic operator lands between $1,800 and $3,800. A wide double swing or sliding gate with a heavy-duty operator, new footings, keypad entry, and safety photocells runs $3,500 to $6,500. Solar operators add $300 to $800 over mains-powered units, but on long driveways they’re usually cheaper than trenching conduit.
What moves the number most is the post condition. If we can reuse existing steel or concrete posts, the job stays lean. If the wood posts have rotted below grade, as many in Alderwood Manor have, expect new footings and that cost is quoted up front. The price you’re quoted is the price you pay. Always. Call (877) 610-2993 and we’ll come measure, put numbers on paper, and you’ll agree before any work starts.

FAQs - Gate Installation in Alderwood Manor
No permit is required if you’re swapping an existing gate on existing posts and not changing the structure. But if the job includes new post footings, widening the opening, or structural fence changes, it crosses into Snohomish County permitting and inspection authority, not Lynnwood or any city hall. We identify which trigger applies to your specific project during the estimate, so you’re not filing with the wrong jurisdiction. Call (877) 610-2993 and we’ll sort it out.
Yes, but the panel needs to be sized for canopy shade, not the open-sun spec. Under red alder and Douglas fir canopy, a 10-watt panel underperforms and the battery drains, especially with a heavy double gate cycling several times a day. We spec 20 to 30 watt panels with deep-cycle batteries for shaded Alderwood Manor sites, and we mount the panel where it catches the longest daily sun window. Call (877) 610-2993 for an exact sizing for your driveway.
It depends on the post, not the hinges. In Alderwood Manor, sagging almost always traces to post-base rot from decades of rain and debris buildup. If the post is sound, new heavy-duty hinges and a lift assist usually fix it. If the post crumbles when probed, replacing hinges alone buys you a year. Fix the panel without the post and you’ll fix it twice. We’ll assess it in person and tell you straight. Call (877) 610-2993.
For a double gate over 10 feet wide or a heavy wood panel, you need a heavy-duty swing or sliding operator rated above the actual panel weight, with a lift assist, safety photocells, and ideally a loop detector for vehicle exit. Many Alderwood Manor farm gates were built with hardware that predates modern operator standards, so the motor has to work around that legacy, not fight it. We install Viking and DoorKing units sized for the full assembly. Call (877) 610-2993 for a spec for your gate.
Gate post footings in Alderwood Manor should go at least 24 to 30 inches deep, and deeper for wide or heavy gates, to get below the saturated topsoil and stay stable through our wet winters. We pour footings with a concrete collar that sheds water away from the post base, because 38 inches of annual rain pooling at the footing is what kills posts in this area. Call (877) 610-2993 and we’ll dig to the depth your gate actually needs, not the minimum.

We installed a solar gate opener on a 40-year-old double swing gate along a red alder-lined driveway in Alderwood Manor recently. The hinge posts had rotted below grade from nearly 40 inches of annual rain and constant canopy debris, so we poured new post footings and switched the operator to a lift-assisted swing system with safety photocells and a keypad entry, avoiding any trenching for mains power across the long driveway. That’s the kind of job we do regularly out here, and we’d be glad to look at yours.
