Call (855) 275-6878

We’ve worked the deep lots and clay-heavy soil of Alderwood Manor long enough to know this isn’t generic suburban gate work. The original 1920s plat map divided farmsteads into deep, narrow parcels — many driveways exceed 150 feet — and early gate posts were often hand-dug into heavy clay without concrete footings, a practice that still causes seasonal gate racking today. If your property sits on one of these old berry farm lots near 148th Street SW or along the original Alderwood Manor plat, you’re dealing with soil conditions that standard installation specs simply don’t account for. We are. Call (855) 275-6878 for a free estimate — David will walk your driveway and tell you exactly what the clay and canopy are doing to your gate before we quote.

Our Gate Installation Services in Alderwood Manor

Swing Gate Installation

Swing gates remain the most common request we get on Alderwood Manor’s older farmstead properties — they match the rural character, and many driveways already have the post spacing for a standard 12–16 foot single or double-leaf setup. But character without engineering fails fast here. We install swing gates with galvanized or stainless-steel hinges rated for marine humidity, set posts in 36-inch concrete footings below the frost line, and specify hardware that won’t seize up two winters from now under the conifer canopy. For historic lots near the original Alderwood Manor plat, we can source ornamental hardware that nods to the 1920s farmhouse style without sacrificing modern function.

Sliding Gate Installation

On the deep driveways that exceed 100 feet — common on the old berry farm lots — a sliding gate often makes more sense than a swing gate that needs 12–14 feet of clear arc space. We install cantilever and track-mounted sliding systems with galvanized steel track and sealed bearing rollers that resist the moisture trapped by Alderwood Manor’s dense Pacific Northwest canopy. For one property off 148th Street SW, our crew replaced a rusted-out swing gate with a LiftMaster pneumatic-slide opener, stainless-steel hinges, and a galvanized track, then set new 6×6 posts in 36-inch concrete footings to resist the clay’s expansion cycle. The gate hasn’t racked in three seasons.

Double Gate Installation

Double gates solve the width problem on farmstead driveways that were originally built wide enough for trucks or equipment — 16 to 20 feet is typical on the deeper Alderwood Manor lots. The challenge is synchronization: both leaves must meet flush despite independent post movement in clay soil. We use adjustable hinge systems and, where budget allows, synchronized openers that compensate for minor seasonal shifts without binding. Every double gate we install in Alderwood Manor gets post footings 6 inches deeper than standard spec — the extra depth anchors the system against the heave cycle that skews lesser installations within a year.

Driveway Gate Installation

Whether you’re securing a gravel farmstead lane off 36th Avenue W or a paved approach to a mid-century ranch near Alderwood Manor’s eastern edge, driveway gates need to handle daily use in conditions that range from muddy ruts to frost-heaved asphalt. We assess your specific approach grade, drainage pattern, and soil composition before recommending materials. On clay-heavy sites, we often specify aluminum or vinyl-clad steel frames over raw steel — the material cost runs 15–20% higher, but the hardware lasts twice as long in Alderwood Manor’s moisture-trapping environment.

Pedestrian Gate Installation

Pedestrian gates on Alderwood Manor properties serve a dual role: access for foot traffic and a visual match to the main driveway gate. We build them to the same hardware and footing standards as our larger gates — shallow-set pedestrian posts fail just as fast in clay soil, and they’re harder to adjust once the gate starts dragging. Matching styles, matching durability.

Security Gate Installation

Security gates for Alderwood Manor properties range from simple keypad-controlled barriers to full access control integration with video intercom and remote entry. We work on the brand you already have — or specify new — and we integrate with existing LiftMaster, DoorKing, or Elite systems where possible. The security hardware is only as reliable as the posts holding it; we don’t install access control on footings we wouldn’t trust ourselves.

Trusted Brands We Service in Alderwood Manor

We maintain factory-familiar fluency across nine major gate systems, and we stock parts locally for the brands we see most in Alderwood Manor: Ghost Controls for solar-compatible residential openers on remote lots without nearby power, DoorKing for heavy-duty commercial-grade access control, and Elite for smooth, quiet operation on estate-style installations. Mighty Mule hardware rounds out our inventory for budget-conscious replacements that still outlast big-box alternatives. Because we carry these parts in our local inventory, most Alderwood Manor customers aren’t waiting a week for a hinge kit or circuit board — we’re back on-site with what’s needed, often the same day.

Common Gate Installation Problems We See in Alderwood Manor Homes

• Un-footed wooden posts heaving in clay soil. The original 1940s–50s farmstead practice of setting posts directly in Alderwood Manor’s expansive clay — no concrete, no gravel drainage — causes gates to rack and drag seasonally rather than fail at a single point. We see repeat service calls year after year on the same properties until someone digs the old posts out and does the footings right.
• Marine humidity and conifer canopy accelerating hardware corrosion. Standard steel hinges, latches, and springs in Alderwood Manor’s persistent overcast humidity, compounded by ground-level moisture trapped under dense Pacific Northwest canopy, corrode 2–3 years faster than in drier suburbs. We specify galvanized or stainless hardware as standard on every Alderwood Manor install — not as an upsell, but as minimum viable durability.
• Rot-prone pre-pressure-treated lumber failing at ground contact. Older farmstead swing gates built before modern pressure-treatment standards rot through at the post-ground line, especially on deep driveway runs where water collects and never fully dries. We replace with modern treated or composite posts, or specify aluminum frames where the aesthetic allows.
• Opener systems underspecified for gate weight and wind load. Alderwood Manor’s open lots and farmstead exposures catch more wind than sheltered suburban courts. A 16-foot double gate in a 25-mph gust loads the opener motor far beyond its steady-state rating. We size openers with a 2x safety factor and specify pneumatic or hydraulic operators on the largest installations.
