Gate sags or drags
A leaning or settled post dropping the leaf.
Gate posts that lean, rot, or have moved
Gate Post Repair in Concord, CA
Gate post repair in Concord, CA is the headline structural job, not an afterthought: a gate is only as square as its posts, and most sagging, dragging, and non-latching gates trace back to a post. The work covers post plumb and movement, concrete footing condition, gate drop, and post reset or reinforcement — and a post reset that ignores why the post moved will move again.

About this service
What Gate Post Repair in Concord Involves
Concord conditions shape these faults. In Concord, gate trouble often starts underground. Local contractors report expansive clay that swells when winter rain soaks it and shrinks as it dries in summer, so posts lean, gates drop out of square, and latches stop lining up. Mature tree roots can heave a post the same way, and on hillside lots near the Diablo foothills a gate that swings uphill drags, binds, and strains its operator. Summer heat warps wood, ages coatings, and stresses opener electronics and batteries, while winter wetness and soil contact drive rust at grade level. This is the Concord post story in full: seasonal clay swell and shrink, root heave from mature trees, and hillside slope all move posts, and the repair has to account for the cause, not just the lean.
In Concord, post work is headline work, not an afterthought: expansive clay plus root heave make post and footing work the cause behind most sagging, dragging, and out-of-square gates. A post is judged on three things — its plumb, its footing and concrete condition, and the gate drop it produces — and a new gate hung on a moving post will not stay square no matter how well the leaf itself is built. Post diagnosis therefore starts underground, at the footing, and works up to the leaf.

What is included
What Our Gate Post Repair Includes
Most post jobs include a footing diagnosis and the repair itself: post plumb in two planes, footing and concrete condition, soil and root heave, gate drop, and hinge attachment, with the post reset, reinforced, or replaced and the gate re-hung square.
✓
Post movement diagnosis
Plumb, footing condition, and surrounding soil and roots assessed to find why the post moved.
✓
Post reset
Leaning posts reset plumb with footing work suited to the site.
✓
Post reinforcement
Posts reinforced where reset alone will not hold, including hinge-side posts under heavy leaves.
✓
Footing repair
Failed or undersized concrete footings repaired or replaced.
✓
Gate re-hang and alignment
Gate re-hung, hinges adjusted, and latch re-aligned once posts are true.
How it works
How Our Gate Post Repair Process Works
01
Phone call
Call 925-265-8944 during business hours, Monday through Sunday, 8:00 AM to 8:00 PM, and describe what the post shows: a leaning post, a gate that drops or drags, a latch that misses its strike, a post that wobbles, or cracked or broken concrete at the base. Whether the lean is new after a wet winter or gradual over years helps separate clay movement from root heave or a failed footing before anyone travels.
02
On-site inspection
Post plumb is checked in two planes first, then footing and concrete condition, then soil, drainage, and root heave at the base, then gate drop and hinge attachment, and finally the leaf itself, swung or rolled to show how much of its fault is post and how much is hinge or frame.
03
Quote on inspection
Once the fault is found, you get a quote on inspection before work starts. No figures are quoted sight-unseen, because the fix depends on whether the answer is bracing, a post reset, footing work, or a post replacement — and on what the soil and roots at the base will allow.
04
Repair and safety testing
The repair is completed and the gate is swung or rolled through its full travel and latched square, with post plumb re-checked under the leaf's weight, not just with the leaf lifted off its hinges.
05
Walkthrough
You are shown what was done and what to watch for — lean returning after a wet and dry cycle, root growth at the base, drainage pooling at the footing, and latch alignment — so a moving post is caught before the leaf starts dragging again.
Tools & methods
Tools and Methods We Use
Post and footing diagnostic equipment, used so a plumb fault, a footing fault, a root-heave fault, and a hinge or frame fault are told apart before the post is reset.
Multimeter and Voltage Tester
Used on an automated gate to test supply voltage at the control board and motor and signal at the safety sensors, separating an operator fault from a post fault; on a manual gate the diagnosis stays with the post, footing, and leaf.
Level and Tape Measure
Used to check post plumb in two planes, gate drop at the free end, and latch alignment after repair.
Hand and Power Tools
Used for post, footing, hinge, and hardware adjustment and replacement, including bracing, digging, and concrete work, without stripping fixings.
Concord causes
Why Gates Fail in Concord
Expansive clay moves posts
What happens
Winter-saturated clay swells and summer-dry clay shrinks, so posts lean, gates drop out of square, and latches stop lining up across the seasons — and mature tree roots heave a post the same way, which is why a post repair checks the ground, not just the post.
What the repair addresses
What a technician checks first: plumb against hinge wear, by lifting the leaf at its free end and sighting the post in two planes. A plumb post with a sagging leaf points to hinges or frame; a leaning post points to the footing, the clay, or the roots — and only the footing answer is a post repair.
Heat, wood, and coatings
What happens
Summer heat dries clay and shrinks it away from footings, while winter wetness saturates clay and swells it, rots timber posts at grade level, and rusts metal posts at soil contact — a post moves with the seasons and rots or rusts where it meets the ground.
What the repair addresses
Repaired versus replaced depends on the post and its footing: a post that has leaned but is sound is reset and reinforced, a footing that has failed is reworked, and a post rotted through at grade or rusted through at its base points toward replacing the post rather than bracing a failed member.
Hillside slope and shared-gate wear
What happens
Hillside lots near the Diablo foothills load posts unevenly and drain water toward their bases, and gates used many times a day cycle their posts and hinges hardest — slope, drainage, and cycle count all shorten a post's settled life.
What the repair addresses
A common misdiagnosis to avoid: re-hanging a leaf square on a moving post only buys the time until the next wet season — the post and footing are the repair, and the leaf follows them, not the other way around.
Problems we solve
Common Gate Post Repair Problems in Concord
Safety note for automated gates: current UL 325 practice calls for two independent means of entrapment protection for each entrapment zone, in each direction of travel, and the two means must be of different types — for example inherent force sensing plus photo eyes or a safety edge. If a monitored sensor faults or is disconnected, the operator should not run. Safety sensors must never be taped over, bypassed, or disconnected to force a gate closed, and controls should sit where a person using them cannot contact the moving gate.

Post movement shifting the latch away from its strike.
Post leaning visibly

Mostly expansive clay: winter-saturated clay swells and summer-dry clay shrinks, moving posts out of plumb across the seasons, with mature tree root heave adding to it block by block. Footing condition and drainage are checked alongside the lean.
Often, yes — a post can be reset plumb with footing work, or reinforced where reset alone will not hold. A post rotted through at grade is replaced rather than reset.
Every job starts with an on-site inspection and a quote on inspection — no figures are quoted sight-unseen, because the right fix depends on the gate, the post footings, and the operator. Call 925-265-8944 during business hours, Monday through Sunday, 8:00 AM to 8:00 PM, to arrange a visit.
