Fast, Reliable Electric Gate Repair Across Union Hill-Novelty Hill
An electric gate that won’t open, won’t close, or reverses partway through its travel is a genuine security problem in Union Hill-Novelty Hill, where long rural driveways and unincorporated King County property lines mean your gate is often the only thing between the road and your home. Most electric gate repairs in Union Hill-Novelty Hill run between $180 and $520 before parts, and our crew can typically have a technician on site within 24 hours, often same day for opener failures, from our Seattle dispatch. Call (903) 417-0793 and talk to a live person. We will quote the repair before we start, and the price on your invoice is the price we agreed to at the door.

As Electric Gate Repair specialists, we focus on one trade. No appliance calls, no garage door side work. We fix gates, openers, keypads, and safety systems, and we have been doing it inside the Relay Home Co. family since 2009.
Why Calder Gate Repair Is Union Hill-Novelty Hill’s Preferred Electric Gate Repair Company
Union Hill-Novelty Hill sits outside any city limits. That small fact changes how gate work gets done here. King County permitting governs the installation, not a city building department, and many of the driveways along Union Hill Road, Novelty Hill Road, and the surrounding parcels are long enough that voltage drop becomes the difference between a gate that operates and a gate that stalls. We plan for that on every visit. A gate motor on a 200-foot run of undersized wire will trip its limit switch repeatedly, and the fix is not another motor. It is the conductor. A company that has not worked this corridor may not look for that first.
Calder Gate Repair is led by Nico Alvarez. Every call is answered by a real human, 24/7, from the Relay Home Co. dispatch. Our technicians are background-checked, arrive in uniform, and carry live arrival tracking so you know when we will be at your gate, not a vague four-hour window. Our 365-Day Done Right Promise says it plainly: if the repair fails within 365 days, Calder returns at no charge. A free second visit is included with every repair we perform in Union Hill-Novelty Hill, not as an add-on, not as a policy you have to ask about. It is written on every job.
We work on the brands Union Hill-Novelty Hill homeowners actually have: LiftMaster, FAAC, Mighty Mule, and more. And we hand you a written price before any work starts. Always.
Automatic Gate Repair in Union Hill-Novelty Hill
Automatic Gate Repair in Union Hill-Novelty Hill usually means one of two things: the gate panel is moving wrong, or the operator is not moving it at all. On a swing gate, the number one failure we see out here is a sagging panel that was re-hung onto a hinge post that was never reset. The post is the actual failure. The panel just shows the symptom. On slide gates, packed snow and ice collect in the track during the freeze-thaw cycles that come through the Novelty Hill corridor from December into March, and the gate will stop mid-cycle or reverse because the photocell beam got blocked. The repair is often simpler than it looks: clear the track, re-aim the sensor, test the reversal. But if the hinge post has shifted, that is a groundworks job, not a hinge adjustment. Expect $220 to $480 for automatic gate repair in Union Hill-Novelty Hill before parts, with the post reset on the higher end.
Hinge Post Reset and Panel Re-Hang
A swing gate that drags at the latch end, or one that it has been “fixed” before but is sagging again within a year, usually needs the hinge post pulled, the footing re-poured to proper depth, and the post set plumb before the panel goes back on. We do not re-hang a panel onto a moving post and call it done. That is how the cycle repeats.
Slide Track Cleaning and Sensor Re-Aiming
Wind-thrown fir debris and snow pack are the usual culprits on slide gates here. If your gate opens a foot and stops, the problem is often not the motor. It is the safety photocell pair seeing an obstruction or a track full of compacted ice. We clear it, re-aim the beam, and run the gate through its travel several times to confirm it holds.
Electric Gate Motor in Union Hill-Novelty Hill
Electric Gate Motor replacement or repair in Union Hill-Novelty Hill is a voltage-sensitive job, and that is why a lot of DIY and generic handyman attempts fail out here. The motor is the muscle of the system. But on a long run from the house panel to the gate, the real problem is often the conductor feeding it. Undersized wire over 150 feet will cause the motor to stall under load, trip its limit, or chatter on startup. We always check supply voltage at the motor before condemning it. A motor that tested “bad” elsewhere may test fine once the conductor is sized correctly. Genuine motor failures here typically run $280 to $550 for the motor itself, and $350 to $650 installed in Union Hill-Novelty Hill, depending on the operator and whether the run from the panel needs attention.
Voltage Drop Testing on Long Driveway Runs
Before we replace anything, we test the supply. Union Hill-Novelty Hill driveways are long. A 300-foot run on 12-gauge wire will not carry a gate motor reliably. The fix can be a heavier conductor, a closer sub-panel, or a higher-voltage motor matched to the load. We will tell you what we find, show you the readings, and price the correction before we do it.
Limit Cam and Reversal Testing After Motor Work
Any time we service or replace a motor, we cycle test the gate for entrapment reversal. That means we put physical resistance in the gate’s path and confirm the motor reverses direction and stops. On automatic gate operators, this is not optional. It is UL 325. Every job we finish in Union Hill-Novelty Hill gets this test before we leave, with you watching if you want to.

Trusted Brands We Service in Union Hill-Novelty Hill
We are factory-familiar with LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Union Hill-Novelty Hill homes lean heavily on LiftMaster for swing gates and FAAC for hydraulic operators on the larger rural parcels. We keep the common parts for those on our service vehicles and stage the rest from Seattle, so a FAAC control board or a Mighty Mule arm typically turns around in one to two days for Union Hill-Novelty Hill calls. You will not wait a week for a part while your gate sits open.
Common Electric Gate Repair Problems We See in Union Hill-Novelty Hill Homes
- Sagging swing gate panels on a hinge post that was never reset. The post moves, the panel drops, and the gate jams at the latch. Re-hanging the panel onto the same footing is a temporary fix that fails again. We re-pour the footing and set the post plumb.
- Voltage drop on long driveway runs. Gates on the larger parcels off Union Hill Road and Novelty Hill Road often have 200 to 400 feet between the house panel and the operator. Undersized wire chokes the motor. We test supply voltage before replacing anything.
- Snow, ice, and fir debris jamming the slide track or blocking the photocell. Winter storms bring wind-thrown branches from the surrounding firs, and the freeze-thaw cycle packs ice into slide tracks. The gate reverses partway or stops entirely. Clearing and re-aiming the sensor usually solves it.
- Limit switch failure from repeated stalls. A motor that has been stalling against a misaligned gate wears out its limit cams. The symptom is the gate stopping short or running past its close point. We service the cams and set the travel correctly.

FAQs About Electric Gate Repair in Union Hill-Novelty Hill
If the motor hums but does not move the gate, if it stalls partway, or if it trips its breaker repeatedly, the operator may be repairable. We test supply voltage first, because on Union Hill-Novelty Hill’s long driveways, voltage drop often looks like a dead motor. If the motor itself has failed or the control board is fried, replacement is usually the smarter spend. We will show you the test readings and price both paths before you commit. Call (903) 417-0793 to schedule the diagnostic.
Yes. Any automatic gate operator installed in King County, including Union Hill-Novelty Hill, must meet UL 325 entrapment protection standards. That means working safety photocells, a reversing edge or equivalent, and proper force settings. If we touch your operator or replace a motor, we test the reversal with physical resistance before we leave, and we document it on your invoice.
The most common reason in Union Hill-Novelty Hill is a blocked or misaligned safety photocell, either from snow and ice on the track or wind-thrown fir debris across the beam. The operator thinks something is in the path and reverses. We clear the obstruction, re-aim the sensor pair, and cycle-test the gate. If the reversing continues after that, the problem is usually in the limit cams or the control board. Call (903) 417-0793 for a same-visit diagnosis.
Yes. We service LiftMaster, FAAC, and seven other major brands from our Seattle-stocked parts inventory. LiftMaster is common on the estate-style swing gates in the eastern Union Hill parcels, and FAAC hydraulic operators show up on the longer commercial-style driveways off Novelty Hill Road. We carry the boards, arms, and sensors for both on our trucks.
No, and we will tell you that up front. A proper gate installation in Union Hill-Novelty Hill involves post footings that have to cure, a power run that may need to be trenched from the house panel over a long driveway, safety edges, and reversal testing. That is ordered, scheduled work measured and priced in writing before we start. Fast is fine for repairs. Installation gets done right instead.
Call (903) 417-0793 now for a free estimate. A live person answers, day or night. We will quote your repair in writing before we turn a single bolt, and you will get a digital invoice you can pay from your phone. Union Hill-Novelty Hill deserves a gate that works when you need it to, and Calder Gate Repair is here to make that happen.
