Why Calder Gate Repair Is Kent’s Preferred Electric Gate Repair Company
Kent homeowners have a specific problem: swing gates that work fine all summer, then bind and stall after the first wet winter. That’s glacial till and heavy clay soil doing what it does. We know these soils. We know the neighborhoods, from the older subdivisions off 104th Ave SE to the newer East Hill developments near 132nd Ave SE. Our techs understand that in Kent, a gate that stops working in November is often a footing problem, not a motor problem, and they check both before quoting anything.
Every Calder tech arrives in uniform, background-checked, with a live arrival time you can track on your phone, the same way you’d track a rideshare. No four-hour windows, no “sometime this afternoon.” Kent customers get their diagnosis in plain English, a written price in hand, and the option to approve or decline before a single bolt turns. Nico Alvarez runs our team with one rule: the number on the invoice is the number agreed to at the door.
Scheduling for Kent is coordinated from our Seattle metro dispatch office, but crews live here and serve Kent locally. That local presence matters when a gate fails at 10pm on a rainy February night and you can’t get your car out. A live person answers at (903) 417-0793, every time.
Electric Gate Motor in Kent
An Electric Gate Motor in Kent often gets blamed for what is actually a structural problem. In our experience, about half of the gate opener motors we’re called to replace in Kent are fine. The real issue is a hinge post that has heaved in saturated soil, a wheel running out of alignment, or a control board getting bad voltage from a failing limit switch, the small sensor that tells the gate when to stop. We test the motor under load before recommending anything.
What Replacement Involves
A motor replacement starts with removing the arm or piston from the gate, verifying voltage at the operator, and confirming the gate leaf moves freely by hand. If it doesn’t, a new motor will fail the same way the old one did. That’s why our Kent quotes include footing and alignment checks first. Motor swaps on a single swing gate typically run $380 – $650 with parts, depending on brand and access.
When Kent Homeowners Actually Need One
You need a new motor when the capacitor is swollen, the gearbox has stripped, or the motor draws full amperage but won’t turn the gate. If the gate groans, buzzes, or trips its thermal overload repeatedly, that’s a motor working too hard. On Kent’s East Hill, we also see motors fail early on driveways with steep grades where the operator size was undersized from the start. We’ll tell you honestly if a replacement is required, and we’ll put the price in writing first.
Gate Access Control in Kent
Gate Access Control in Kent covers everything that tells your gate who to open for: keypads, remotes, intercoms, loop detectors, and the control board that ties them together. After a long Kent rainy season, we get a spike of calls from homeowners whose keypads have gone dead or whose gate opens only with the remote, not the entry pad. Water intrusion behind the keypad faceplate is the usual culprit.
Keypads and Remotes
Keypad repair or replacement in Kent typically runs $120 – $240. That includes diagnosing whether the fault is the keypad itself, the wiring run, or the receiver board. We program and test every remote we supply, and we can clone most existing transmitter frequencies, including Viking and DoorKing systems. If your remote works intermittently, we check battery voltage, transmitter range, and the receiver antenna before selling you anything.
Loop Detectors and Safety Sensors
Loop detectors, the wires buried under your driveway that sense a car, fail quietly in Kent’s wet soils. A saturated loop can hold a gate open far longer than it should, or refuse to trigger at all. We test loop frequency and continuity, and if a loop is dead, we’ll tell you whether it’s worth saw-cutting a new one or switching to a photo-eye or radar sensor instead. Safety photocells are non-negotiable: every automatic gate must pass a UL 325 entrapment check, and we test those sensors on every repair visit.
Trusted Brands We Service in Kent
Our techs are factory-familiar with the brands Kent homeowners actually have: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That covers virtually every swing and slide gate operator installed in Kent from the 1990s to today. When a DoorKing board fails on a 90s subdivision gate off 116th Ave SE, we can usually match the part locally or have it in hand within a day. For Viking and Elite systems on East Hill, we keep common limit switches, capacitors, and remotes stocked for fast turnaround. You won’t wait a week for a part we can pull from our own inventory.

Common Electric Gate Repair Problems We See in Kent Homes
- Swing gates binding and stalling. Kent’s glacial till and wet winter soils heave shallow hinge posts, so the gate leaf drags or binds and the operator cuts out mid-travel. We re-set the post deeper with better drainage, then calibrate the operator.
- Slide gates grinding in leaf-clogged tracks. October through February, Kent’s slide gates collect maple leaves, fir needles, and grit in the track and rack. The gate works harder, the motor draws more amps, and the overload trips. We clean, lubricate, and re-align the rack and pinion.
- Dead entry keypads after rain. Water gets behind the faceplate or into an underground splice, and the keypad stops triggering the gate. We replace the weather seal, re-make the splice, and test the system under load.
- Missing or failed safety photocells. A gate without working photo eyes fails a UL 325 entrapment check, which is both a safety violation and a liability. We install and align new sensors on every repair where the existing ones are dead or misaligned.

FAQs About Electric Gate Repair in Kent
Not usually. In Kent, a gate that stalls and reverses mid-travel is more often a hinge post that has heaved in saturated soil, dragging the leaf out of alignment so the operator reads an obstruction and reverses. We test the gate by hand, check the post footing and drainage, then test the motor under load before recommending replacement. If the motor is genuinely failing, we’ll show you the amperage reading and quote a written price. Call (903) 417-0793 and we’ll diagnose it on site.
Yes. We install swing and slide gate operators across Kent, and most single-gate installations take one to two full days once parts are on hand, plus time for any needed concrete cure. A complete installation includes the operator, safety photocells, proper ground or power run, and full UL 325 enforcement and reversal testing. We never promise same-day installation: it’s measured, quoted, and scheduled. Call (903) 417-0793 for a free measure and written quote.
UL 325 requires that every automatic gate have functioning entrapment protection: safety photocells, a reversing mechanism, and proper force settings. We test all three on every repair we do in Kent. If your gate doesn’t reverse when it meets resistance or your photo eyes are missing or misaligned, it fails. We repair or replace what’s needed and re-test the system before we leave. Call (903) 417-0793 and ask about a UL 325 safety check.
Check the keypad’s battery first if it’s wireless; if it’s wired, rain has likely found a seam in the faceplate or an underground splice. In Kent’s wet climate, we see this constantly from late October through March. Don’t open the keypad housing if you’re unsure, water intrusion plus live low-voltage wiring is better handled by a trained tech. We’ll diagnose it, replace the failed part, and reseal the housing. Call (903) 417-0793 for a same-day service call in Kent.
We service LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That covers the vast majority of residential swing and slide gate operators installed in Kent over the last 30 years. If your operator is an older or discontinued model, we can usually source the part or retrofit a compatible current board. Call (903) 417-0793 with your brand and model and we’ll tell you right away what we can do.
Why Kent Gate Failures Start in the Soil, Not the Motor
Here’s what makes Kent different. Our area sits on glacial till, dense, compacted sediment left by the glaciers that once covered the Puget Lowland. Over that till, developers in the 1970s through 90s built thousands of homes with swing gates mounted on posts set in shallow concrete footings. They worked fine in summer. But Kent’s winter rain saturates the soil, the clay swells, and shallow posts heave upward. A quarter inch of movement at the post translates to a gate leaf that drags, binds, and eventually stalls the operator. Homeowners on East Hill, where driveways slope steeply, feel this the worst.
That’s why we don’t treat Kent gate repairs as motor-only jobs. We look at the post first. On a steep East Hill driveway off 132nd Ave SE, our tech found a LiftMaster swing gate that opened halfway, stalled, then reversed, classic binding from a hinge post that had heaved in saturated soil after a wet Kent winter. We pulled the old footing, re-set it deeper with proper drainage, swapped the operator’s limit cams, and tested the safety photocell and reversal. The gate has cycled cleanly since. That’s the difference between a patch and a repair that holds.
