Gate repair in San Diego runs $85 to $450 for most handyman calls. A hinge swap or latch replacement lands on the low end. Fixing a badly sagging cedar side-yard gate with a new anti-sag kit, hardware, and post re-set runs $250 to $450 depending on how much the post has shifted.
Gates take more abuse than any other part of a fence. They swing open and closed hundreds of times a year, carry their own weight against a single post, and sit in direct sun. San Diego’s heat accelerates the usual problems, and our coastal salt air adds rust to the mix. Here’s what breaks, what it costs to fix, and when rebuilding is the smarter call.
The most common San Diego gate problems
Sagging wood side-yard gates
This is the top call we get. A cedar or redwood side-yard gate starts sagging at the latch corner, dragging the ground or refusing to close flush. Two things drive it.
First, the hinge screws strip out of the post. Sun-baked cedar softens over years. The screws spin freely in the holes, and nothing is holding the hinge to the post anymore. The fix is to remove the hinge, fill the holes with hardwood dowels and construction adhesive, let that cure, and re-drive the screws into solid material. That alone costs $85 to $175 and often solves the sag completely.
Second, the gate frame itself has racked. Wood gates are rectangles, and without a diagonal brace, they want to become parallelograms over time. An anti-sag kit, sometimes called a turnbuckle brace or cable kit, runs a steel cable or turnbuckle diagonally from the top-hinge corner down to the latch-side bottom corner. Tightening the turnbuckle pulls the gate back square. Materials run $25 to $60; labor adds $75 to $125. Total: $100 to $185 for the brace alone, or bundled with the hinge repair for $175 to $300.
Hinge and latch replacement
Standard strap hinges on wood gates last 8 to 15 years in San Diego before the coastal air causes rust and pitting. A rusted hinge that can’t hold its own weight needs replacement, not penetrating oil. Upgrading to galvanized or stainless hardware costs more upfront but survives the marine layer far longer, especially within a mile of the coast.
Latches fail for the same reasons: rust binds the spring mechanism, or the latch body cracks. A new self-latching gate latch runs $15 to $40 in materials. With labor, budget $85 to $175 to have a handyman swap both the latch and strike plate and adjust the gate alignment.
Gate posts loosening in concrete
A gate post takes asymmetric stress every time the gate swings. Over years, the post rocks in its footing, the concrete cracks, and the post leans. Once the post leans, the gate can’t close square no matter what you do with the hinges.
Re-setting a gate post means digging out the old concrete, straightening the post, and pouring a new footing. This is more involved than a standard fence post reset because gate posts need a wider and deeper footing to handle swing load. Plan on $250 to $450 per post depending on depth, access, and whether the post itself needs replacement. Our fence repair cost guide covers post repair costs across the full fence line if you have multiple posts involved.
Pool fence gates: self-closing and self-latching requirements
California requires pool barrier gates to be self-closing and self-latching. The latch must be on the pool side of the gate and positioned so a child cannot reach over or through the gate to operate it. If your pool gate doesn’t meet these requirements, that’s a safety and liability issue, not just a maintenance one.
A handyman can replace the hardware on an existing pool fence gate: install a spring-loaded self-closing hinge, swap to a compliant self-latching mechanism, and adjust the gate so it closes and latches reliably from any position. Budget $150 to $275 for hardware and labor. If the gate or its post is in poor condition, rebuilding the gate is often combined with the hardware upgrade.
Gate repair cost table
| Problem | Typical fix | Cost range |
|---|---|---|
| Stripped hinge screws, gate sags at corner | Dowel and re-drive screws, re-hang hinge | $85 to $175 |
| Gate frame racked, won’t close square | Anti-sag turnbuckle kit + adjustment | $100 to $185 |
| Both hinge repair and anti-sag brace | Combined visit | $175 to $300 |
| Rusted hinge replacement (per hinge) | Galvanized or stainless swap | $85 to $150 |
| Latch replacement and realignment | New self-latching latch, adjust gate | $85 to $175 |
| Gate post re-set in new concrete footing | Dig, set, pour, cure | $250 to $450 |
| Pool fence gate hardware upgrade | Self-closing hinge + compliant latch | $150 to $275 |
| Full gate rebuild, same post | New frame, pickets, hardware | $350 to $650 |
Repair vs. rebuild: how to decide
Repair makes sense when the post is solid, the gate frame has reasonable bones, and the problem is hardware or a moderate sag. If the frame is warped beyond square, the wood has dry rot in the rails or stiles, or the gate has been dragging long enough to destroy the bottom rail, rebuilding the gate on the existing post is often the same cost as layering repairs on a failing structure.
A rebuilt side-yard gate using cedar or redwood, quality galvanized hardware, and a proper diagonal brace typically runs $350 to $650 installed. That’s a new gate that will last another 15 to 20 years with normal maintenance. Patching a failing frame repeatedly rarely gets you there.
When the problem is a damaged post or a rotted fence run on either side of the gate, that’s a different scope. For new gate installation or a full fence run that needs to be replaced alongside the gate, a dedicated fence company like Fence Pros San Diego handles that work at scale, which is the better call when you’re looking at 20 or more linear feet. For anything that’s fundamentally a repair, start with our fence and deck repair service.
If you’re still deciding whether to repair or replace the larger fence run, our fence repair vs. replacement guide lays out the decision framework with specifics on post condition, material age, and cost crossover points.
Carpentry work on custom or decorative gates
Decorative wood gates, arched tops, or gates with inset panels need carpentry skills beyond a basic hinge swap. Rebuilding a custom gate, trimming a swollen gate that’s binding in the frame, or adding trim work to match the fence style falls under carpentry work. See our carpentry services if the scope is more than hardware and standard framing.
Frequently asked questions
How much does gate repair cost in San Diego?
Most handyman gate repairs in San Diego run $85 to $300 for a single visit covering hinge replacement, latch swap, anti-sag kit installation, or a combination of those. Gate post re-setting in new concrete runs $250 to $450 per post. A full gate rebuild on an existing post runs $350 to $650. Automatic driveway gate repair involves motor and electronics and is a separate specialty.
Why does my wood gate keep sagging after I fix it?
A gate that keeps sagging usually has one of two root causes: the hinge screws are stripping out of the post because the wood is soft or the holes are oversized, or the gate frame has no diagonal brace and physics will keep racking it. Fixing one without the other means the problem comes back. The right repair combines solid hinge re-attachment and an anti-sag turnbuckle brace on the gate frame.
Can a handyman fix a pool fence gate to meet California requirements?
Yes. A handyman can install self-closing hinges and a self-latching mechanism on an existing pool fence gate to bring it into compliance with California pool barrier requirements. The latch position, spring tension, and gate alignment all need to work together so the gate closes and latches reliably every time. Budget $150 to $275 for hardware and labor.
How long does a wood gate last in San Diego?
A well-built cedar or redwood gate with galvanized or stainless hardware lasts 15 to 25 years in San Diego with normal maintenance. Paint or sealant every 3 to 5 years extends the life of the wood significantly. Gates near the coast or in full afternoon sun degrade faster because marine air rusts hardware and UV exposure dries out and splits the wood. Upgrading to stainless hardware at the next repair adds years without rebuilding the whole gate.
When should I replace the whole fence instead of just fixing the gate?
If the fence posts on either side of the gate are also loose or rotted, fixing the gate alone is a short-term solution. A gate can only be as solid as the posts it’s hung on. If the fence panels adjacent to the gate are in poor shape too, a targeted repair becomes patchwork on a system that’s failing. That’s when a full fence replacement or a larger fence repair project makes more sense. For existing fence damage alongside the gate, Fence Pros San Diego’s fence repair service handles those larger scopes.
Does gate repair require a permit in San Diego?
Repairing or replacing a like-for-like gate on an existing fence generally doesn’t require a permit in San Diego. Building a new gate, changing fence height, or structural work near a property line may trigger permit requirements depending on your city or HOA. When in doubt, check with your local planning department before starting work that changes the fence structure.
