Hal Gatewood started this company in 2001, and his name is still on the shop and every invoice we hand you.

Our Gate Repair Services in Thornton
Hinge & Post Repair
A gate that sags in the hinge post, not in the middle, and that is where we start. Thornton’s heavy clay soil expands and contracts with every freeze-thaw cycle, heaving posts out of plumb by spring. We dig down, reset the post in a deeper concrete base, and weld in a new hinge bracket so the gate hangs level again. In 80241 subdivisions, we regularly see whole blocks where three or four gates develop hinge fatigue the same year simply because they were all installed in the same 1990s building wave.
Automatic Gate Repair
Thornton sits on the open Front Range plains with no windbreak to the northwest. Chinook events can gust past 50 mph and snap the arm on an automatic opener or strip the gear box on a heavier swing gate. We service LiftMaster, Viking, Ghost Controls, DoorKing, and Elite operators, and we keep common boards and safety photocells on the truck. If your gate opens halfway and reverses, or the motor runs but nothing moves, we diagnose the problem on the first visit and quote the fix before any work starts.
Gate Realignment
When the frame stays solid but the gate drags on the concrete pad or the latch no longer lines up, the problem is usually post movement or hinge wear. We bring the gate back to square with shims, welded plates, or a full post reset depending on what the footing looks like. The goal is a gate that closes with a firm thunk, not a grinding scrape.
Weld & Rust Repair
Ornamental iron gates in northern Thornton take a beating from freeze-thaw moisture trapped in factory welds. We grind out rust, clean the affected area, and weld new bracket stock where the old material has thinned. If an HOA requires the same powder-coated finish, we match the color and texture before we are done. We also handle aluminum gates that have cracked along stress points near the hinge mounts.

Trusted Brands We Service in Thornton
We are certified to service nine major gate operator brands, and for Thornton customers we stock parts locally for the ones we see most often: LiftMaster, Viking, Ghost Controls, DoorKing, and Elite. If your HOA spec calls for a specific operator model, we already know what fits and what the approval process looks like. We would rather have the exact board or arm on hand than make you wait a week for a part out of a warehouse in another state.
Common Gate Repair Problems We See in Thornton Homes
- Chinook wind damage: Westerly and northwesterly side gates take the brunt of 50+ mph gusts on the open plains. Frames get torqued, hinge welds snap, and automatic arms fail. We see the same thing across whole blocks the morning after a high-wind advisory.
- Clay heave under gate posts: Front Range clay swells and shrinks through every freeze-thaw cycle. Posts shift out of plumb, gates drag, and latches stop lining up. This is a spring problem in Thornton as reliably as the crocus bulbs.
- HOA-spec hardware failures: Hundreds of 80241 subdivisions were built in the 1990s and 2000s with the same six-foot ornamental iron or powder-coated aluminum gate models. When the hardware reaches the end of its life, entire neighborhoods need the same hinge, post, and operator work in the same two-year window.
- Wide acreage openings north of Eastlake: Farm-style gates with tall leaves and long spans put enormous strain on hinges and operators. When dual swing arms are not synchronized, one side does most of the work and burns out faster.
Pricing for Gate Repair in Thornton, CO
Straight numbers, because you deserve them before you get a bill. Hinge and post repair in Thornton runs $180 to $320 on a standard six-foot ornamental gate.

Wide acreage gates with dual operators run higher, and we will write the number down before any work begins.

FAQs - Gate Repair in Thornton
Your neighbors’ gates fail together because they were installed together. Thornton’s 80241 suburbs went up in massive building waves through the 1990s and 2000s, and whole subdivisions got the same ornamental iron or aluminum gate models in the same two-year window. When those hinges and operators reach the end of their service life, the whole street needs the same repair. Add in Chinook wind events and freeze-thaw clay heave, and the failures cluster even more. We rebuilt a sagging 16-foot ornamental iron swing gate in the Eastlake area after Chinook winds torqued the frame and cracked the hinge post footing. Our crew reset the post in a deeper concrete base, welded in a new hinge post bracket, and reinstalled the LiftMaster operator with fresh safety photocells. The HOA required the same powder-coated aluminum picket spec, so we matched the finish exactly before the final inspection. Call (877) 610-2993 for a repair quote on your gate.
The clay under northern Thornton shrinks and swells seasonally, which slowly pushes gate posts out of plumb. Each freeze-thaw cycle moves the post a little more, and by spring the gate drags, the latch misses, and the hinges bind. The fix is not a bigger shim. The fix is resetting the post in a deeper concrete footing with proper drainage so the clay cannot work on it the same way again. Quoted upfront, agreed before we dig.
Yes, but it has to be sized for the gate’s weight and span. A solar-powered operator that works on a six-foot suburban gate is not going to move a 20-foot farm gate through a 50 mph Chinook. For wide acreage openings north of Eastlake, we size the panel, battery, and operator to deliver enough torque without draining the system every time the wind pushes against the leaves. If you already have a solar setup and the gate is failing, we can inspect the battery bank, panel angle, and operator rating. Call (877) 610-2993 for an honest answer on what will actually work.
In most 80241 subdivisions, yes. HOA design committees in Thornton’s master-planned communities often mandate a specific gate height, material, color, and sometimes even the operator brand. We repair to spec, which means we match the existing finish and hardware rather than just bolting on whatever is easiest. If your HOA needs a written quote or a spec sheet before approving the work, we can provide that. Plan on the approval taking a few days in most Thornton neighborhoods.
UL 325 is the federal safety standard for automatic gate operators, and it requires working entrapment protection, usually in the form of monitored safety photocells, contact edges, or both. If your gate operator reverses when it hits an obstruction but has no photocells, or if the photocells are old enough that they do not self-monitor, your gate does not meet the current standard. We check the entrapment protection on every automatic gate repair in Thornton and will flag it in writing if it is not right. Working on an automatic gate operator that does not meet UL 325 is not something to leave for later. It should be fixed by someone who does this work professionally, because a gate that closes when it should not can genuinely hurt someone. Call (877) 610-2993 and we will inspect yours.
