Gate installation in Ontario usually means replacing a 1950s-70s wrought-iron gate that has outlived its original post footing, or adding an automatic operator to an older manual gate as a security upgrade. The ground heave from Inland Empire clay changes how we set posts and plumb anchors, and the hot summers punish undersized operators. If you’re weighing a new gate or a repair on an old one in the 91761, 91762, or 91764 ZIP codes, call Montclair Gate Repair at (866) 371-3309 for a straight assessment.
Why Ontario Homes Are Different
Most central and east Ontario neighborhoods are tract-home blocks built between the 1950s and 1980s, and the driveway gates on those streets are original ironwork. The frames themselves often hold up well. What fails is the foundation. Ontario sits on expansive clay that swells with winter rain and contracts through the hot dry summer. After a wet January or February, that clay lifts and shifts. The result, on older central-Ontario blocks especially, is a gate post that has moved an inch or more out of plumb. A gate that closed cleanly in November drags on the driveway by March. The repair is not a new hinge; it is re-setting the post, re-plumbing the anchor, and only then re-hanging the leaf.
Add the Santa Ana winds and summer temperatures near 100°F, and you get a second failure pattern: hinges that sag under repeated thermal stress, operators whose motors overheat, and battery backups that cook in full sun. A gate company in Ontario has to know both problems. We see them every season.
Styles & brands we work with





Our Main Ontario Services
Ontario homeowners and property managers call us most often for two things: a gate that will not open or close correctly, and an electric operator that has stopped responding. Both are covered under their own Ontario pages below.
Gate Repair in Ontario
This covers the mechanical side: sagging wrought-iron leaves, bent or broken hinges, damaged posts, latch misalignment, and gates that have dropped out of level after a wet winter. On Ontario’s clay, post heave is the single most common cause of gate sag on older blocks, and fixing it means more than a shim: we dig, re-set, and re-anchor the post so the repair holds through the next rain season. For the full Ontario breakdown, see Gate Repair in Ontario.

Electric Gate Repair in Ontario
Automated operators add wiring, control boards, safety loops, and motors to the same aging hardware. When an Ontario homeowner adds a swing operator to a 1960s manual gate, the old post often cannot hold the new load, and the operator tears loose or faults out. We trace the fault, whether it is the board, loop, motor, or wiring, and fix the actual cause. For the full Ontario breakdown, see Electric Gate Repair in Ontario.

Gate Installation in Ontario
New gate installation in Ontario is usually a replacement job on an existing fence line, and the success of the project depends on the post footings. The original 1950s-70s posts on many central and east Ontario properties were set shallow, meant to hold a manual leaf, not an automated operator. When we install a new gate on that line, we set posts below the clay movement zone, plumb them to the current conditions, and size the hinge and operator for the actual leaf weight. That is the difference between a gate that works for twenty years and one that drags by the following spring. For the full scope of what we cover, see Gate Installation.
Driveway Gate Installation
Signs you need it
The old gate has rusted through at the hinge, the post has heaved more than a shim can fix, or the leaf is too far gone to re-hang square.
What it costs in Ontario
A new residential driveway gate in Ontario typically runs $3,000 to $9,000 installed, depending on material and whether automation is part of the job.
How we do it
We pull the old leaf and hardware, dig new post holes to the proper depth for Ontario clay, set and plumb the posts in concrete, then hang and adjust the new gate for a clean closing line.
Automatic Gate Installation
Signs you need it
You want to open the gate without leaving the car, or the old operator has failed and the gate sits dead at the driveway.
What it costs in Ontario
Adding an automatic operator to an Ontario driveway gate usually lands between $2,500 and $7,000, depending on whether the existing post can carry the load.
How we do it
We check the post and hinge load first, then mount the operator, run power, set the travel limits, wire the safety loops, and test the full open-close cycle several times.
Sliding Gate Installation
Signs you need it
Your driveway has a slope or tight turn that makes a swing gate impractical, or you want a heavier commercial-style leaf for a multi-car driveway.
What it costs in Ontario
A sliding gate in Ontario typically starts around $4,500 to $12,000 or more, since it requires a track, a cantilever or roller system, and a matching operator.
How we do it
We set the track or cantilever footing, build and hang the leaf, install the operator and rack, then calibrate the limits and safety edges to the actual gate travel.
Electric Gate Installation
Signs you need it
You want full automation, including keypad, intercom, or vehicle sensor entry, on a newly built or completely replaced gate.
What it costs in Ontario
A full electric gate installation in Ontario, including the gate, operator, and controls, generally runs $5,000 to $15,000 depending on the setup.
How we do it
We handle the complete scope, from the gate and operator to the conduit, wiring, safety equipment, and access controls, including the power run from the house or panel.
What Gate Installation Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Driveway gate (manual, standard steel/wrought-iron) | $3,000 – $9,000 |
| Automatic operator added to existing gate | $2,500 – $7,000 |
| Electric gate with operator and controls | $5,000 – $15,000 |
Will the price change after the job starts?
No. We quote the full installation before any work begins, and that price is agreed and locked. The only time a number changes is if you add scope, like a keypad or intercom, after the quote.
Does gate installation in Ontario need a permit?
Most residential gate replacements on the same footprint do not require a permit in Ontario, but some masonry columns and low-voltage power runs can trigger city or HOA review. We check the specifics for your street before the job starts.
Brands We Service in Ontario
We work on equipment from FAAC, BFT, Linear, and Viking, plus a broader range of nine major brands, across both residential and commercial gates. Keeping parts for those brands on the truck means the first visit is usually the only visit. You can see the full list on our brands.

AfterPricing for Gate Company in Ontario, CA
Every gate price in Ontario has to account for the clay. Posts set shallow in the original tract-home build will move, and a job quoted without digging into that is a job that fails in eighteen months. The ranges below reflect the local reality and the full fix.
| Service | Typical range in Ontario |
|---|---|
| Gate repair (hinge, latch, minor alignment) | $150 – $500 |
| Post reset and re-plumb (single post) | $450 – $1,200 |
| Automatic gate operator repair | $250 – $900 |
| Control board diagnostic and replacement | $300 – $1,100 |
| Driveway gate installation (manual) | $3,000 – $9,000 |
| Sliding gate installation | $4,500 – $12,000+ |
| Automatic operator added to existing gate | $2,500 – $7,000 |
| Electric gate installation (full) | $5,000 – $15,000 |
| Gate opener replacement | $400 – $1,500 |
| Safety loop replacement | $350 – $1,000 |
Prices in Ontario push upward when the job involves a post that has heaved more than an inch, a power run longer than fifty feet, or an older operator that needs the board and motor addressed at once. The price you are quoted is the price you pay, agreed before any work starts.
Neighborhoods We Serve in Ontario
We cover the full city, from the older central blocks around Euclid Avenue and Holt Boulevard out to the 1980s tracts in the north and east, and down toward the 91761 industrial strips where commercial gates need the same attention.

- Central Ontario (historic tract blocks)
- North Ontario (1980s-90s homes)
- East Ontario (near the 15 and Milliken)
- South Ontario (mixed residential and commercial)

FAQs About Gate Company in Ontario
For a gate stuck open, stuck closed, or that will not respond to the remote, we usually can. Older Ontario tract homes have a high rate of post-heave failures after rain, so spring is a heavy season for us, but we keep emergency capacity open. Call (866) 371-3309 in the morning for same-day dispatch.
Many Ontario neighborhoods, especially newer developments and some central tracts, have HOA or architectural review requirements for driveway gates. If your street has an association, we recommend checking their design rules first. We can usually work within their specs for style and height.
Yes. Our commercial work covers the same brands and the same fault tracing as the residential side, applied to higher-cycle operators, larger sliding leaves, and multi-tenant access systems. We service commercial and multi-unit properties throughout South Ontario and the industrial areas near the 10 and 15.

What Ontario Customers Say
"We had a hydraulic arm leaking fluid onto the driveway. Replaced, cleaned up the stain as best he could, and it's been dry for months."
— Wade Miller"Our slide gate had been dragging for months and getting worse. Turned out the chain was stretched and one of the guide rollers had seized. Both replaced, and he adjusted the limits so it stops properly at both ends now."
— Riya Shah"Fixed the immediate problem. He was honest that the operator is near end of life and I should budget for a replacement, which I appreciate even if it wasn't what I wanted to hear."
— Neil Hayes
