Fence Gates: How to Price Them and Build Them So They Don't Sag
Gates are 5% of the fence and 80% of the callbacks. They're also the most commonly underpriced element on fence quotes. Both problems have the same root: treating a gate like four feet of fence instead of like a small machine.
Why gates deserve their own price. A gate is hardware, reinforcement, precise hanging, and the only part of the fence with moving parts and daily use. Our rule: gates are always a separate line item, priced per gate by width and type, never blended into footage. A 4' walk gate carries an hour-plus of skilled labor plus hardware that ranges from $40 to $200+ depending on quality — bury that in per-foot pricing and you're donating it. Bonus: a visible gate line item gives the homeowner a place to feel in control of the budget ("we could do one gate instead of two") without touching your fence margin.
Why gates sag — the physics in one paragraph. A gate is a cantilever: all of its weight hangs off one post, trying to rotate the latch side toward the dirt, forever. Sag is the post leaning, the frame racking out of square, or the hinges yielding — usually in that order. Every anti-sag technique attacks one of those three.
Build rules that prevent the callback
- Over-build the hinge post. It carries everything. Bigger footing, deeper set, and reinforcement — this is exactly where our steel-insert build earns its keep; a steel-cored hinge post in a proper footing removes the #1 sag cause before the gate's even hung. On wide gates, treat the post spec like a small structural decision, because it is.
- Keep the frame square. Quality vinyl gate kits have internal frames; cheap ones are panels with hinges and a prayer. Diagonal bracing or cable kits must run the correct direction (compression brace from bottom-hinge toward top-latch; cable the opposite diagonal) — half the field-built gates we replace have the brace backward, which is worse than no brace.
- Don't cheap out on hinges. Self-closing, adjustable, properly rated hinges cost $30–60 more than the bargain pair and erase years of nuisance calls. Pool-code gates legally require self-closing/self-latching — and pool compliance is skilled work you should price as such, not absorb.
- Mind the gaps. Set hinge-side and latch-side clearances to the hardware spec, account for seasonal movement, and check swing over the ground's high point, not just at the post line. The "gate won't latch in spring" call is a frost/clearance problem you can prevent in October.
Double drives and wide openings: drop rods, center rests, and honest conversation with the homeowner about whether a 10' double gate for once-a-year trailer access is worth its lifetime of fuss versus an 8' with a removable section. Selling the right gate is a trust play that pays in referrals.
Quote language that wins: name the build, briefly — "4' walk gate: steel-reinforced hinge post, internal-frame gate, self-closing stainless hardware." Three specifics that justify your gate price against every vague "gate included" quote it's sitting next to on the kitchen table.

Frequently asked questions
Why do fence gates sag?
A gate is a cantilever hanging all its weight off one post, so sag comes from the hinge post leaning, the frame racking out of square, or hinges yielding — usually in that order. Prevention targets all three: an over-built (ideally steel-reinforced) hinge post in a proper footing, an internal-frame gate, and rated adjustable hinges.
How should contractors price fence gates?
Always as separate line items by width and type, never blended into per-foot fencing. A 4-foot walk gate carries over an hour of skilled labor plus $40–200+ of hardware; burying that in footage donates it. A visible gate line also gives homeowners a budget lever that doesn't touch fence margin.
Which direction should a gate's diagonal brace run?
A compression brace runs from the bottom hinge corner up toward the top latch corner; a tension cable runs the opposite diagonal. Roughly half of field-built gates have the brace backward, which is worse than no brace at all.
