Fast, Reliable Gate Access Control Across Flower Mound
Gate access control in Flower Mound usually comes down to four things: getting the right hardware on the post, running power and data to it correctly, making sure the HOA finish matches, and dealing with what the Blackland Prairie clay does to the post itself. We handle all four. If a keypad, card reader, phone entry unit, or video intercom is down in Wellington, The Preserve, Lakeside, or anywhere else in Flower Mound, we can be there the same day in most cases. Call (940) 394-8744 and a live person answers, day or night.
This is Hal Gatewood’s company. The name is on the shop. We have been fixing and automating gates since 2001, and we service Flower Mound regularly from our Dallas-Fort Worth office. Every access control job carries the same 90-Day Done Right Promise in writing, and the price is quoted and agreed before any work starts. No surprises at the door.
- Key takeaway: Most Flower Mound access control failures are not the keypad or reader itself. They are the wire, the power, or the post moving in the clay. We find the real cause before touching hardware.
- Key takeaway: HOA finish matching in Wellington, The Preserve, and Lakeside matters. We match bronze, black, and custom powder-coats before mounting new hardware, and we handle the approval process.
- Key takeaway: On sloped driveways, a keypad that “sometimes doesn’t work” is usually a post or safety photocell alignment problem. Not a keypad problem.
Why Gatewood Fence & Gate Is Flower Mound’s Preferred Gate Access Control Company
Flower Mound is not a flat suburb. It rolls. Drive nearly any street in Wellington or The Preserve and you will find a driveway with a noticeable grade, an ornamental iron gate on it, and an operator that has been fighting that grade for fifteen years. That combination is exactly where access control fails. A builder-grade operator sized for a lightweight aluminum gate gets hung with a 900-pound ornamental iron leaf. The gate sags in the post. The safety photocells go out of alignment. Then the keypad gets blamed. Hal has been pulling panels off these systems long enough to know that the keypad is almost never where the problem starts, and he will say so plainly. We rebuild the post, run the right wire, re-align the limits, and then the access control works like it should have from the first day.
Flower Mound homeowners keep our number for a reason. When a gate will not open at 6 a.m. and a car is stuck in the driveway, the person who answers the phone is a person who can actually talk through the problem. Not a voicemail. Not a call center three states away. Every call is answered live, 24/7. We show up in clean uniforms, background-checked, and we leave the job site tidier than we found it. The person who shows up is the person whose name is on the invoice.
We carry stock for the access control brands Flower Mound homes actually have: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Having that stock locally means less waiting when a board fails or a keypad dies. And because we weld on site, a cracked hinge post or a bent rack does not turn into a two-week replacement drama. Hal fixes the gate in your driveway.

Everything below is installed, programmed, and backed by the same written promise. If it is not done right, we make it right. One call brings Hal back. No runaround.
Keypad Entry
A keypad on a Flower Mound gate post lives a hard life: full sun in August, freezing rain in February, and a post that shifts in clay soil every wet spring. We install weather-sealed, metal-housing keypads and we mount them on a bracket that does not flex with the post. If an existing keypad stops working after heavy rain, we test the wire before we touch the keypad. That test usually finds the real problem. Typical keypad replacement or new install in Flower Mound runs $250 to $600, depending on whether we are running new wire or reusing a sound conduit.

Remote Control and Receiver Upgrades
Most Flower Mound gates have a single receiver and two or three remotes that were programmed fifteen years ago. Adding a modern receiver with rolling-code security and phone-programmable remotes is straightforward. We also tie remotes into smart access so you can issue and revoke a code for a housekeeper, a landscaper, or a teenager from your phone. Receiver and remote packages in Flower Mound typically run $300 to $650 installed.

Phone Entry Systems
Phone entry lets a visitor call a number from the keypad and reach your cell phone directly. No network cable at the post needed, as long as there is cellular signal, which Flower Mound has no trouble with. These systems work well for the long, gated driveways common in The Preserve and Lakeside, where a doorbell camera at the gate just would not pick anything up. Installed phone entry units for a single gate run $650 to $1,200 in Flower Mound, including programming and testing.

Card Reader and Video Intercom
Card readers make sense for Flower Mound homes with frequent service providers: pool companies, housekeepers, dog walkers, lawn crews. We install Wiegand and OSDP readers that integrate with the operator board, and we can issue or revoke cards on site. Video intercoms add a camera at the gate that talks to an app on your phone, so you can see and talk to whoever is there. For Flower Mound homes with long drives, this is often the better option than a Ring on the house. Card reader installations run $400 to $900. Video intercom systems run $800 to $1,800 depending on whether we are running new conduit from the house.

Smart Access Retrofits
The builders in Flower Mound did not run network cable to the gate post. We can still make a gate smart. Cellular-based and Wi-Fi bridge controllers get a signal from the house to the gate without trenching a Cat6 line. You get app control from anywhere, temporary codes, and a log of every open and close. Retrofit smart access on an existing Flower Mound gate runs $500 to $1,100.

Trusted Brands We Service in Flower Mound
We are factory-trained on the brands actually sitting on Flower Mound driveway posts: LiftMaster, DoorKing, Elite, and Mighty Mule, plus FAAC, BFT, Linear, Viking, Ghost Controls, and more. The builder-era installations in Wellington and Lakeside are mostly LiftMaster LA400 or FAAC 391 operators, and we know exactly how those units fail and what to replace them with. We stock boards, remotes, keypads, and loop detectors for these brands locally, so a Flower Mound repair usually does not wait on a parts shipment. When an operator is beyond saving, we size the replacement for the actual gate weight, not the builder spec.
Common Gate Access Control Problems We See in Flower Mound Homes
- Keypad dead after rain, but the operator still has power. The wire between the house and the post was direct-buried in clay. Clay holds water and shifts. The wire corrodes or severs. We trench new conduit and run shielded 18-gauge cable, then test the keypad. The keypad was never the problem.
- Photocells out of alignment every few weeks. On a sloped Flower Mound driveway, the post heaves enough to angle the photocells slightly every wet spring. The beam misses the reflector, the gate reverses or refuses to close, and you stand there holding the remote like a fool. We reset the post and re-align the cells, then dig the footing deeper so it stops happening.
- Builder-grade operator burning out on an ornamental iron gate. A LiftMaster LA400 was never meant to swing a heavy Wellington iron leaf. We replace it with a commercial-rated FAAC C720 or DoorKing 9100 on a dedicated 20-amp circuit, and we re-set the hinge post before the new operator goes on. Fix the operator without the post and you will fix it twice.
- Slide gate rack teeth shearing on a slope. Flower Mound’s rolling terrain means one gate leaf rises while the other sinks as the clay moves. The rack and pinion engage at the wrong angle, and teeth shear. We re-level the track, re-lay the rack, and re-align the limit switches. Then the access control responds properly, because the operator is no longer fighting the grade.

How Flower Mound’s Soil and Slopes Break Gate Access Control
Flower Mound sits on North Texas Blackland Prairie clay. That clay swells after spring rain and shrinks and cracks in a hot, dry summer. Post footings poured 2 feet deep, which was standard in the 1990s builds, heave out of the clay enough to put a gate leaf visibly out of plumb. On a sloped driveway, which Flower Mound has more of than anywhere else in the DFW basin, the heave pushes one side of the gate up while the other sinks. Now the leaf binds. The operator motor strains. The safety photocells, which are mounted on those same shifting posts, go out of beam alignment. The keypad and card reader, also on those posts, sit at a slight angle. That angle is enough to bind a mechanical keypad button or misalign a card reader’s sensor. This is not a problem in flat, sandy-soil Lewisville. It is the whole story in Flower Mound.
In The Preserve, we serviced a LiftMaster slide gate operator on a sloped driveway where the original builder ran only 14-gauge landscape wire for the keypad and loop detector. After a wet spring, the clay heaved the hinge post 3/4 inch out of plumb. The gate dragged. The safety photocells fell out of alignment every few weeks. We reset the post in a deeper concrete footing, re-ran proper 18-gauge shielded cable in new conduit from the house to the operator and keypad, and re-leveled the track so the rack and pinion engaged cleanly. The gate has cycled without a fault code since. That is the fix most Flower Mound access control problems actually need: not a new keypad, but a post that stays put and wire that has not been eaten by clay.

FAQs - Gate Access Control in Flower Mound
The keypad is probably fine. The wire feeding it is the problem. Most Flower Mound homes built between 1995 and 2015 have keypad and loop detector wires direct-buried in Blackland clay. That clay holds water and shifts with every wet spring, corroding or severing the wire. The operator keeps working because its power line is heavier and in conduit. The keypad stops because its wire is thin, unshielded, and lying in wet clay. We test the wire first, then trench new conduit and run 18-gauge shielded cable. That fixes the keypad for good. Call (940) 394-8744 for a free wiring check.
Yes. We match the exact bronze or black powder-coat on your existing hardware before mounting new access equipment. We handle the HOA approval process too, and we will get color-match sign-off before installing anything so you do not get a violation letter. This is routine for us in Wellington, The Preserve, and Lakeside. Expect a couple of extra days for finish matching and HOA approval, but no guessing. The final hardware is photographed against the existing finish before it goes on the post.
No. When the gate sags on a sloped Flower Mound driveway, the post has moved and the gate leaf has shifted enough to bind the operator or misalign the safety photocells. The keypad may be perfectly functional, but the operator board is getting a fault or the photocells are blocking the close command. The fix is resetting the hinge post, re-leveling the track, and re-aligning the photocells. Then the keypad responds every time. Call
Yes. Builders in Flower Mound rarely ran network cable to gate posts. We use cellular-based or Wi-Fi bridge controllers that get a signal from the house to the gate without trenching a Cat6 line. You get app control from anywhere, temporary codes for service providers, and a log of every open and close. Retrofit smart access on an existing Flower Mound gate typically runs $500 to $1,100. Free estimate before any work. Call (940) 394-8744 and we will check your signal strength at the post.
The right fix is replacing the operator with a commercial-rated unit sized for the actual gate weight. A LiftMaster LA400 was not built to swing a heavy ornamental iron leaf on a sloped Lakeside driveway. We install FAAC C720 or DoorKing 9100 operators on a dedicated 20-amp circuit, and we re-set the hinge post and re-align the limits before the new unit goes in. That combination ends the burnout cycle. Typical full replacement with new operator and post work runs $1,800 to $3,200 in Flower Mound. Call (940) 394-8744 for an exact number for your gate.

What Flower Mound Customers Say
Trusted by homeowners across Flower Mound and surrounding areas.
"Driveway gate had been dragging for two years and two other companies told me the whole thing needed replacing. Hal reset the posts, rehung it and it swings like it did when it went in. A fraction of the price of a new one."
"He came out in the snow to get our gate closed after a delivery lorry clipped it, then came back in the spring to do the proper repair when the ground had thawed. Only charged for the second visit."
"Hundred and forty feet of cedar privacy fence, all posts set in concrete, all of it dead level on ground that is anything but. He walked the line with me twice before a single hole was dug."
