Preparing a Round Rock Driveway for a New Metal Gate
What should be done before any gate work begins?
Before any gate work begins, the owner should settle where the gate will sit, clear the opening and mark what lies underground. A gate built across the wrong line, or into a buried pipe, costs days to undo. In Round Rock, TX the work is made easier by one habit: walk the opening with a tape measure and a notepad a week before the crew arrives, and write down everything that could be in the way.
The steps below follow the order a careful crew works in. Skipping ahead is how a gate ends up an inch short of its post or a hinge ends up over a sprinkler line.
Where exactly does the gate go?
The gate goes on a line the owner can prove belongs to the property. Williamson County lots often have a recorded plat, and many subdivisions around Forest Creek and Brushy Creek also carry easements that run along the front or side of the lot. A gate set inside an easement can be ordered out later, so the plat and any survey should be pulled out and read before a post hole is marked.
Mark the corners of the opening with stakes and string. Step back to the street and look at the line as a driver would. A gate that sits flush with the front of the house reads very differently from one pushed back thirty feet, and the choice changes how a car needs to approach.
What has to be cleared from the opening?
Everything that stands in the swing path, the track path or the post locations has to move. The common offenders are listed below, along with what usually needs to happen to each.
| Item in the way | Why it matters | Usual solution |
|---|---|---|
| Sprinkler heads and lines | Posts and tracks cut them, and spray soaks the footing | Cap and reroute away from the gate line |
| Mailbox post | Blocks the arc of a swing leaf | Move it or choose a slide gate |
| Tree roots | Block post holes and lift pavement | Shift the post location, never cut a large root without advice |
| Landscape lighting | Wires lie shallow near driveways | Mark the run and keep post holes clear of it |
| Loose gravel and mulch | Jams tracks and hides the true grade | Rake back to bare ground along the gate line |
How are buried lines located?
Buried lines are located by calling the Texas utility locating service before anyone digs. Gas, water, electric and communication lines all run near driveways, and a post hole auger can cut through any of them in seconds. The locating crews mark each line with paint or flags, and those marks need to stay visible until the posts are set. Irrigation lines are not covered by the public service, so the owner has to know where those run, which is easier with the original installation drawings or a quick look at where each sprinkler head sits.
What does the slope of the driveway change?
The slope of the driveway decides whether the gate can swing, and in which direction. Lay a long straight board across the opening and set a level on it. If the ground rises toward the house, a leaf swinging inward has to lift or the bottom rail has to be cut on an angle to follow the grade. If the ground falls toward the street, the same gate swings freely but may need a stop to keep it from drifting open.
Many driveways in the area have a crown in the middle and fall away to each side, which makes a long single leaf awkward. A pair of shorter leaves, each hinged to its own post, copes with a crown far better. A slide or cantilever gate sidesteps the issue and rolls along the contour.
How does the soil affect the plan?
The soil affects the plan because every post depends on it. Expansive clay soil swells with water and shrinks as it dries, and it can move a footing that was set too shallow. The owner cannot change the clay, but can help the footing by keeping downspouts and sprinkler spray away from the post locations. Soil that stays at a steady moisture level moves less.
Before the crew arrives, take note of where water runs after a storm. A low corner that holds water for a day is a poor place for a post, or at least a place where the concrete collar should be sloped away so the water leaves. A short walk after the next rain tells more than any guess.
Which rules need checking first?
Three sets of rules need checking first. A homeowners association may set limits on gate height, color, material and how far the gate sits from the street. The city may cap fence and gate height near a corner so drivers can see oncoming traffic. And the plat may restrict what is allowed inside an easement. Reading these takes an hour and can prevent a rebuilt gate.
If the neighborhood has an architectural review process, the application usually asks for a sketch, a material and a color. Having a rough drawing ready, with the opening width and the post positions marked, speeds the approval along.
What decisions should the owner make in advance?
The owner should decide on the operation, the material and the finish before the crew shows up, because each one changes the posts. The list below sets out the questions a crew will ask on the first visit.
- Will the gate swing, slide or roll on a cantilever frame?
- Will it open by hand or by a motor, and where would the power and the control wiring run?
- Steel tubing, solid bar or aluminum, and how heavy a leaf can the posts carry?
- Powder coat or brush paint, and which color suits the house and the neighborhood rules?
- Should there be a pedestrian gate beside the driveway gate?
- Who needs to open it: family, delivery drivers, a trash service?
A motor changes the plan the most. Power has to reach the post, usually through a conduit buried in a trench, and the operator needs a rigid mounting point. Deciding that early lets the crew run the conduit before the concrete goes in, which is far simpler than cutting it afterward.
What happens on the day the posts go in?
On the day the posts go in, the crew confirms the stakes, digs the holes below the clay's active zone and sets each post plumb in concrete. The holes are wide, often a foot or more across, and the bottoms are flared so the clay cannot lift the footing. The concrete then needs time to cure, and the gate is not hung until it has. That wait is the part owners find hard, but a post loaded too early will settle out of plumb.
Owners can help by keeping the driveway clear of cars, pets and children, by making sure the crew has water access for mixing, and by staying away from the open holes. A fenced hole is a safe hole.
What should be checked once the gate is hung?
Once the gate is hung, the owner should open and close it several times and watch the latch. The leaf should swing without scraping, stop where it should and latch without lifting or pushing. Check the gap at the latch top and bottom, and compare the two numbers. Look at each weld and each hinge for gaps or bare metal where the finish is thin.
Write down the measurements and keep them. A year later, after a wet spring and a dry summer, measure again. If the numbers match, the posts are staying put. If they do not, the early record shows exactly when and how much the gate moved, and that makes a repair easier to diagnose.
A short checklist to finish
Prepare the line, clear the opening, locate every buried utility, measure the slope, read the neighborhood rules, decide how the gate will operate and keep water away from the posts. Seven small jobs, done in order, make the gate itself go in smoothly.
