Fast, Reliable Gate Installation Across Seattle
A new automatic gate in Seattle should be sized for the actual weight of the gate, set on concrete footings poured below the frost line, and tested for entrapment protection before anyone calls the job done. That’s what we deliver. If you’re in Seattle, from Magnolia to Madison Park, and your current gate sags at the hinge or your operator burned out on a gate that was never right in the first place, we install gates and motor systems that stay square and run clean through wet winters. Call (469) 530-2485 for a written price before any work starts.
Why Carver Gate Repair Is Seattle’s Preferred Gate Installation Company
We work exclusively on gates. Not fences, not decks, not general contracting. That narrow focus matters in Seattle because the soil conditions and rainfall punish sloppy gate work faster than almost anywhere else in the region. Our technicians arrive in uniform, have passed background checks, and carry the parts for nine motor brands so we’re not making a second trip because the truck didn’t have the right limit switch.
Lonnie Burke leads our Seattle gate installation crew. He’s built the local operation around a simple rule: the written quote is the price. Not a starting point. When we survey a Seattle property, we check the post footings, the gate weight, the swing or slide path, and the power run before we put a number on paper. That number doesn’t move at the door.
Every installation carries our 365-Day Done Right Promise in writing. If something we installed fails inside that year, we come back and make it right at no charge. That’s the Garrison Standard, and it’s been the operating rule since 2008.
Electric Gate Installation in Seattle
Electric Gate Installation in Seattle means running line-voltage power to the operator, setting safety photocells and loop detectors, and testing reversal force under UL 325 before we hand the gate over. It’s more than bolting a motor to a post. In Seattle’s wet climate, every electrical connection has to be sealed against rain and road spray, and the operator needs to be sized for a gate that gets heavier every winter as the wood absorbs moisture. A typical Seattle electric gate installation runs $4,500 to $9,500 depending on gate size, operator type, and the power run distance from the panel.
Operator and Control Wiring
We run conduit and sealed junction boxes for every installation. Exposed wiring fails fast in Seattle, especially on driveway approaches where standing water and road spray sit for months. The operator gets a dedicated circuit, not a piggyback off a garage outlet.
Safety Systems and Reversal Testing
UL 325 requires every automatic gate to stop and reverse when it contacts an obstruction, and to hold against entrapment at the leading edge. We test both directions with a force gauge before we leave. A gate that won’t reverse on a child or a dog is not a finished installation.
Driveway Gate Installation in Seattle
Driveway Gate Installation in Seattle starts below ground. Seattle’s glacial soils and constant winter rain saturate post footings, so a hinge post set in a shallow hole will lean, and the gate will sag and bind, no matter how good the hardware is. A proper driveway gate here needs concrete footings poured below frost line, with drainage so water doesn’t pool against the post base. We price driveway gate installation in Seattle at $5,000 to $12,000. The range covers gate material, operator, footing work, safety edges, and the power run. A typical project in Ballard or Queen Anne runs toward the middle of that range when the site allows a clean power run.
Footings and Post Setting
We dig deep, set the post in concrete, and slope the surrounding grade so water drains away. This is the single biggest factor in whether a Seattle gate still opens in five years. Shallow footings are how most failed gates here start.
Slide Versus Swing Configurations
A slide gate needs a level track and a clear run beside the driveway. A swing gate needs room to arc and hinges that can carry the full gate weight without deflecting. On sloped Seattle lots, slide gates often make more sense because the ground falls away from the driveway, but the track has to be set on stable subgrade with drainage underneath. We’ll explain both options and the trade-offs for your specific lot before you choose.
Trusted Brands We Service in Seattle
Our Seattle crews install and service operators from FAAC, BFT, Linear, and Viking, along with LiftMaster and four other major brands. That means we match the operator to the existing gate and the site conditions rather than pushing one product line. If you’re replacing a BFT slide operator in Seattle, we have the right mounting hardware and control boards on hand. If a Linear swing operator failed at the limit switch, we can diagnose it on the first visit because we know the parts common to those units. Having local parts stock means your repair isn’t waiting on freight from a warehouse in another state.
Common Gate Installation Problems We See in Seattle Homes
- Hinge post rot and settling from wet soils. Seattle’s rain saturates the ground around post footings, and shallow concrete lets posts lean and rot. The gate then sags at the latch side and the operator strains until it burns out.
- Loop detector and photocell failures from water ingress. Rain and road spray get into poorly sealed wiring at driveway approaches. We see loop detectors that stop sensing vehicles and photocells that fault out on the first wet week of October.
- Undersized operators on heavy gates. A cedar or steel gate that’s heavier than the operator rating fails early. The motor runs hot, the limit switches drift, and the board eventually gives up. The fix is matching the operator to the actual gate weight, not the brochure number.
- Gates that were never safety-tested. Some Seattle gates were installed without photocells or proper reversal settings. That’s an entrapment risk on a driveway where kids and pets are present. We correct those installations whenever we touch a gate, and we test to UL 325 before we leave.
Pricing for Gate Installation in Seattle, WA
A pedestrian gate installation in Seattle typically runs $1,200 to $3,500. A single driveway swing gate with a new operator runs $5,000 to $8,500. A double driveway gate runs $7,000 to $12,000, and slide gates run $6,500 to $12,000 because the track and subgrade work add labor. The biggest variables are footing depth, power run distance, gate material and weight, and whether we’re building from scratch or replacing an existing gate and reuse the existing posts.

FAQs About Gate Installation in Seattle
Because Seattle’s glacial soils and constant winter rain saturate post footings, so most failed gates here fail at the hinge post footing before the hardware ever wears out. The post leans, the gate drops, and the latch side drags. The fix is new concrete footings below frost line with drainage, not adjusting the hinges. Call (469) 530-2485 for an exact quote, and we’ll inspect your post condition before suggesting any hardware changes.
Seattle requires electrical permits for wiring new gate operators, and some neighborhoods with design review or historic district rules may require additional approvals for gate structures. We coordinate the permit paperwork as part of the installation. For your specific street in Capitol Hill or West Seattle, call (469) 530-2485 and we’ll work through what your site requires.
Every new automatic gate in Seattle needs photocells or contact safety edges at entrapment points, plus a motor with proper reversal force settings and a manual release. UL 325 is the governing standard, and we test against it before we finish. A gate without those systems is a liability, not a convenience. Call (469) 530-2485 for a free estimate on bringing an existing gate up to code.
Most Seattle driveway gate installations run two to four days, not same day. The concrete footings need to cure before the posts carry full weight, and the operator, power run, and safety testing are all done after the gate is hung. We schedule the work in clear steps and give you a written timeline with your quote. Call (469) 530-2485 and we’ll give you a realistic schedule for your specific gate.
Yes, if the posts are secure and the gate swings true. We check the footing condition and hinge hardware first. In Ballard, we replaced a sagging cedar driveway swing gate that had pulled its hinge post loose from saturated soil. We dug new post footings below the frost line, set the hinge post and gate operator on a concrete pad, installed a LiftMaster swing gate operator with safety photocells, and tested the reversal and entrapment protection under UL 325 before we left. For your existing gate, call (469) 530-2485 and we’ll tell you if it’s a sound base for a new operator.
