AfterFast, Reliable Gate Motor & Opener Across Lawrenceville
A gate motor replacement in Lawrenceville typically runs $650-$1,450 for a standard swing or slide operator, and most repairs are completed in one visit. That’s the short answer. The longer answer depends on what the original builder put in, whether the HOA ever swapped the gate panel for something heavier, and whether the red clay under the posts has been heaving for twenty years without anybody noticing.
We work these subdivisions every week. Gatewood Fence & Gate has been repairing what other companies want to replace since 2001, and in Lawrenceville that usually means undoing what a production builder did in a hurry two decades ago. A live person answers our phone around the clock at (877) 610-2993, and the estimate is free. The price we quote is the price you pay, period, agreed before the first tool comes off the truck.
Why Gatewood Fence & Gate Is Lawrenceville’s Preferred Gate Motor & Opener Company
Hal Gatewood’s name is on the shop and on every invoice. That matters in a place like Lawrenceville, where a lot of people got burned by a national outfit that quoted one number on the phone and presented a different one standing in the driveway. We’re owner-operated, locally owned, and we’ve been doing this since 2001. The address is published. The license number is published. You can look it up, or you can drive over and look Hal in the eye.
What sets us apart in Lawrenceville specifically is that our crews understand what they’re walking into before the gate is even visible from the street. We know the subdivisions off Sugarloaf Parkway, the townhome clusters near 30044, and the older brick-front neighborhoods throughout 30045 and 30046. We know which builders used which operators. We know where the shallow footings are. That means fewer wasted trips and a diagnosis that holds up, instead of a guess that turns into a second bill.
Every job carries the 90-Day Done Right Promise, written plainly on the invoice. If it’s not done right, one call brings us back. Not a runaround, no fine print about “most cases.” We also answer the phone with a live person 24 hours a day, seven days a week. When a gate motor dies during the morning rush and now fifty cars can’t get out of a subdivision, you need a person, not a voicemail.
Standing offers you should know about before you call: $40 off any repair over $200, no trip charge inside the county, a free second opinion on any written estimate you already have, and a permanent 10% discount for seniors and veterans. Those aren’t haggling points. They’re the way we work.
Our Gate Motor & Opener Services in Lawrenceville
Motor Installation
New motor installs in Lawrenceville usually mean replacing a builder-grade operator that was never sized for the gate it’s pushing. The original 1990s spec sheets called for a lighter panel. Then the HOA upgraded to ornamental iron, and the motor has been struggling ever since. We right-size the operator for the actual gate weight, not the original paperwork. That means taking measurements on site, not pulling a part number off the old unit and matching it.
Installation includes new mounting, wiring verification, travel limits set correctly, and safety photocells brought up to current UL 325 standards. Most single-family gate motor installs in Lawrenceville run $900-$1,600 including labor, with slide motors typically slightly higher than swing motors depending on the rail condition.
Motor Repair
Repair is our default position, not our fallback. Hal fixes the gate in your driveway rather than hauling it off or telling you the whole operator needs to go. That’s the difference between a $240 control board replacement and an $1,100 motor swap. We’ll tell you which one you actually need, and we’ll show you the failed part before we replace it.
Common repairs across Lawrenceville include capacitor failures, stripped limit switches, water intrusion in the housing, and contactor wear from voltage drop on undersized wire runs. A typical motor repair in this area runs $180-$475.
Linear Motor
Linear motors are common on the slide gates throughout Lawrenceville’s HOA subdivisions, and the failure mode is almost always the same. The ram or the drive chain was sized for a lighter gate, the HOA changed the panel, and now the motor overheats every summer. We stock linear replacement parts for the most common builders’ operators in the area, which means most repairs happen the same day.
If the linear drive itself has failed, replacement is usually the honest move. A linear motor replacement with full alignment and safety check typically runs $700-$1,250 in Lawrenceville, depending on gate length and post condition. We’ll quote the exact number before we start.
Slide Motor
Slide gates are everywhere in Lawrenceville, especially on the wider subdivision entrances where a swing gate would block a turning lane. Slide motor problems in this county are frequently misdiagnosed. The motor gets blamed when the real problem is a rack misalignment, a rusted guide roller, or a conduit run that was never buried to code and has been losing voltage for years.
We set the rack and pinion alignment before we touch the motor. Then we check the electrical. Often the motor itself is fine, and the repair is a fraction of what a replace-first company would charge. When the motor genuinely has to go, a slide motor swap in Lawrenceville typically lands between $850 and $1,550.

Trusted Brands We Service in Lawrenceville
We’re certified to service nine major gate brands, and in Lawrenceville the ones we see most are Linear, Viking, and DoorKing. Those names went into hundreds of Gwinnett County subdivisions during the 1990s and 2000s buildout, and they’re the operators that are now hitting their first major repair cycle. We keep the common repair parts for these units stocked so Lawrenceville customers aren’t waiting six days on a parts order. When you call about a Linear operator that’s tripping a breaker, the person coming out has likely worked on that same model in a subdivision two miles from you.
If you’re not sure what brand you have, that’s fine. We’ll identify it on the first visit, quote the repair or replacement on the spot, and get your approval in writing before any work begins.
Common Gate Motor & Opener Problems We See in Lawrenceville Homes
Lawrenceville’s specific housing stock creates a specific set of repeat failures. We see the same four issues across dozens of different subdivisions, and they almost always trace back to decisions the production builder made twenty or thirty years ago.
- Builder-grade motors laboring under heavier gate panels. HOAs upgraded to ornamental iron without ever touching the motor. The operator has been running beyond its rated duty cycle for a decade, and it finally gave up. This is the single most common call we run in the Sugarloaf Parkway corridor and the 30044 zip code.
- Post footings heaving in red clay. Gwinnett County’s expansive clay swells during wet winters and shrinks during dry summers. Post footings sized for a light aluminum panel were never deep enough to resist it. The hinge post tilts, the gate binds, and the motor burns out trying to push an out-of-plumb gate. Realignment is the fix, not a new motor.
- Undersized or improperly buried conduit. Original power runs were sometimes 14-gauge wire in shallow trench, never meant for continuous-duty operators with battery charging circuits. Voltage drop under load causes intermittent failure that looks random. It isn’t. The wire run needs to be replaced, and we’ll show you the math on why.
- Missing UL 325 entrapment protection. Gates installed before 2008 mostly lack the required non-contact sensors and reversing edges that are now mandatory. In Lawrenceville, nearly every pre-2008 subdivision entrance gate we inspect needs a safety retrofit. This isn’t code nitpicking. A gate without proper entrapment protection can seriously injure a child or pet, and sensors must be installed and tested by someone qualified to work on high-voltage gate systems.
Pricing for Gate Motor & Opener in Lawrenceville, GA
Lawrenceville pricing runs close to the metro Atlanta average, with two local factors that can move a quote. First, HOA-installed gates tend to require longer wire runs and additional safety equipment, which pushes labor slightly higher on installs near the city’s larger subdivisions. Second, post alignment problems from the clay soil sometimes add a few hundred to a motor repair, because you can’t put a new motor on a binding gate post and expect it to last.
| Service | Typical Range |
|---|---|
| Motor repair (control board, limit switch, capacitor) | $180 - $475 |
| Linear motor replacement | $700 - $1,250 |
| Slide motor replacement | $850 - $1,550 |
| Full motor installation (right-sized, UL 325 compliant) | $900 - $1,600 |
| Battery backup addition to existing opener | $350 - $700 |
| Post realignment before motor work | $200 - $450 depending on post condition |
Every quote is written, explained, and agreed before work starts. There is no trip charge inside the county, and the second opinion on any competitor’s written estimate is free. Call (877) 610-2993 and we’ll give you a real number over the phone in most cases, not a range that expands at the door.

FAQs - Gate Motor & Opener in Lawrenceville
The most common cause is Gwinnett County’s red clay swelling with winter moisture, heaving the gate post out of plumb and making the motor work against a binding hinge. The motor isn’t the problem. The post is. A close second is water intrusion into the operator housing during Georgia’s wet winters, which shorts limit switches and control boards. We fix the post alignment first, then we’ll tell you honestly whether the motor still needs work. Call (877) 610-2993 and we’ll come out for a free assessment.
Yes, and we do it regularly in Lawrenceville, especially in the neighborhoods off Lawrenceville Highway where plenty of gates were hung as manual panels and never automated. The honest thing to know before you start: the job isn’t just a motor bolted to the post. It needs a properly sized operator, a power run that meets code, and safety sensors required by UL 325. If the original post footings are shallow, we’ll address that too, because automation adds constant stress to a post that has never felt it. Expect $1,200-$2,200 for a complete manual-to-automatic conversion depending on gate weight and distance to power.
The motor’s drive train and the hinge post fail first, usually in that order. The original operator was specced for a lighter aluminum panel, and the constant overloading wears out the gears, then the capacitor, then the motor windings. Meanwhile the post, if it’s on a shallow footing, starts to lean. In Lawrenceville, we see this exact sequence in subdivisions across 30044 and 30046 where ornamental iron replaced builder-grade aluminum. Fix the motor without the post and you’ll fix it twice. We’ll quote both before we start, and the price is agreed up front.
If your gate is the primary entrance to a community or a property with only one way in, yes. Lawrenceville gets summer thunderstorms and occasional winter ice storms, both of which knock out power, and a gate without battery backup becomes either a manual-override situation (if you know how) or a stuck gate blocking everyone. We install battery backup systems that keep the gate cycling for 24-48 hours of typical use during an outage, and the cost runs $350-$700 for most residential openers. It also counts toward UL 325 safety compliance, so the retrofit often serves double duty.
UL 325 is the standard that governs entrapment protection for automated gates, including non-contact sensors that reverse the gate before it touches a person or vehicle. Most Lawrenceville subdivision gates went in before 2008, when the current requirements became mandatory. That means they lack the photoelectric sensors and reversing edges now required by code. We bring every gate we touch up to current UL 325 standards as part of the repair. It’s a safety retrofit, not an add-on, and it’s nearly universal on pre-2008 gates in this part of Gwinnett County. Call (877) 610-2993 to schedule a safety check.
We run service in Lawrenceville daily, and most calls in the 30045, 30046, 30049, and 30042 zip codes get same-day or next-morning response. When a gate motor fails and blocks an entire street or a community entrance, we’ll prioritize it like an emergency, because it is one. A live person answers the phone 24/7 at (877) 610-2993, and scheduling is coordinated from our Atlanta metro office, with crews running locally through Lawrenceville all week.
