A single fence gate installation or repair in the Raleigh-Durham area typically runs $275 to $650. Where you land in that range depends on three things: what's actually wrong with the gate, what hardware goes into fixing it, and whether you're dealing with a single walk gate or a wider double/drive gate. Here's how to think about each.
Why gates sag in the first place
A sagging gate is almost never one simple problem — it's usually two or three small ones stacking up. The most common causes, roughly in order of how often they show up:
- Post movement. The gate post has shifted, leaned, or twisted in the ground, throwing the whole frame out of square. This is the expensive one to fix because it can mean re-setting or replacing the post, not just the gate.
- Worn or undersized hinges. Hinges rated for a light gate that's been carrying a heavier one (or years of slamming) stretch out and let the far corner drop.
- Frame racking. Wood or thin metal frames without a diagonal brace slowly rack into a parallelogram shape under their own weight — classic sag, no post problem at all.
- Wood movement. Wood gates expand and contract with humidity swings. In a climate with hot, humid summers and cooler, drier winters, that seasonal swelling and shrinking loosens fasteners and joints over time, which is a big reason wood gates need more upkeep than metal ones.
- Soil conditions around the post. A lot of homes in this area sit on heavy clay soil, which expands when wet and contracts when dry. That movement can work a post loose over several seasons even if it was set correctly to begin with.
A repair visit that's just re-hanging hinges or adding a brace sits at the low end of the $275–$650 range. A repair that involves resetting or replacing a post pushes toward the top of it, and if the post footing has to be dug out and re-poured, it can approach what a full new gate would cost.
Hardware tiers: what you're actually paying for
Hardware is where a lot of the price spread comes from, and it's worth understanding the tiers before you agree to a quote:
- Basic/builder-grade. Galvanized strap hinges and a simple gravity or slide latch. Fine for a lightweight wood or vinyl gate that doesn't get heavy daily use. This is the cheapest hardware and sits at the bottom of the repair range.
- Mid-tier. Adjustable self-closing hinges, a keyed or child-safety latch, sometimes a drop rod for a double gate. These cost more per piece but hold alignment longer and are worth it on any gate that gets opened multiple times a day.
- Heavy-duty. Ball-bearing or industrial hinges rated for heavier wood or metal gates, plus reinforced posts. This tier is standard on wide gates, gates carrying a lot of weight (solid wood privacy panels, ornamental metal), or anywhere the gate takes real abuse — a side yard used to move trash cans and equipment through, for instance.
Upgrading hardware during a repair instead of just replacing what failed is usually a small add-on cost, and it's the single best way to keep a fixed gate from sagging again in a year or two.
Single gate vs. double/drive gate
A standard single walk gate (roughly 3–4 feet wide) is the cheapest and fastest job — less material, less hardware, less structural bracing needed. It sits comfortably within the $275–$650 range for either a straightforward install or repair.
A double gate or drive gate (wide enough for a vehicle, a mower, or a boat) is a different animal. More width means more leverage pulling on the hinges and posts, so it needs heavier posts, often a concrete footing on each side, a center drop rod or cane bolt to keep the two leaves aligned, and heavier-duty hinges across the board. A drive gate install or a repair involving both leaves and their posts will typically run at or above the top of the range noted here, and if you're adding an automatic opener, that's a separate cost on top — treat it as its own project rather than an add-on to a basic gate quote.
Permits and local rules
Raleigh and Durham each set their own zoning rules around fence and gate height, placement near property lines, and corner-lot sight triangles, and requirements can differ by neighborhood or HOA on top of that. Rules and permit thresholds change, so rather than quote a number here that could be out of date by the time you read it, the honest move is to confirm current height limits and whether a permit applies with your city or county planning office before work starts — especially for a drive gate that's taller or wider than a standard residential gate.
Repair or replace?
If the posts are sound and the problem is hinges, a latch, or frame bracing, repair almost always makes sense — it's the cheaper end of the range and a competent job should last years. If a post is rotted, cracked, or has shifted more than an inch or two out of plumb, patching the gate around it is a short-term fix. You'll usually spend less over time by replacing the post now rather than paying for the same repair again next season.
Getting an exact number for your gate
Every gate is a little different — the width, the material, how bad the sag is, whether a post needs resetting. Rather than guess from a general range, the fastest way to get a number that actually applies to your gate is to take a photo of it, describe what's happening (won't latch, dragging on the ground, leaning post, etc.), and get an instant local price range based on that. That's the approach this site is built around, and it beats waiting around for a callback just to find out what a repair might cost.
