Fast, Reliable Gate Repair Across Kensington
Most gate repair calls in Kensington come down to one thing: the hinge post, not the gate panel, has failed. We see it on Arlington Avenue, along the upper loops of Colusa, and throughout the 1970s subdivisions off Rincon Road. Calder Gate Repair dispatches background-checked technicians to Kensington with a live, trackable arrival time, a written price before any work starts, and the 365-Day Done Right Promise on every job. Call (903) 417-0793 and a live person answers, day or night.

Why Calder Gate Repair Is Kensington’s Preferred Gate Repair Company
Kensington does not flatten itself for convenience. Driveways climb, lots step, and gate posts end up seated in retaining walls or cut into slope edges. That is exactly the terrain our technicians read before touching a bolt. We know which Kensington streets have the steep transitions, and we know the failure patterns that come with them. Our team, led by Nico Alvarez, trains on nine leading gate opener brands including LiftMaster, FAAC, and Linear, and every job carries the Gate Repair guarantee that made Calder part of the Relay Home Co. family since 2009.
Kensington homeowners repeatedly tell us the same thing after a repair: the technician arrived when the tracking said they would, explained the repair in plain English, and handed over a digital invoice that matched the quote. No surprises. The Relay Standard, the booking-to-invoice experience we run on, puts a live arrival time, before-and-after photos, and a pay-from-a-link invoice in every customer’s hands. That is what phone-first homeowners in Kensington expect, and it is what Calder delivers.
Driveway Gate Repair in Kensington
Driveway Gate Repair in Kensington almost always starts at the post. Because so many homes sit on hillside lots with stepped footings or retaining-wall bases, the hinge post settles, leans, or cracks at the footing, and the gate panel follows it down. The panel itself is often straight and perfectly serviceable. We re-set the post, re-level the hinges, and get the gate cycling cleanly without replacing panels that do not need replacing.
Most driveway gate repairs in Kensington run $285 – $650 before parts, depending on whether the post needs re-setting, the operator needs realignment, or both. A straightforward hinge replacement on a smaller single gate lands near the lower end. A settled post on a slope, with footing work, lands higher. Full panel replacement is a different conversation, and we never push it when a repair will hold.
Hinge Post and Footing Repair
The post buried in a retaining wall carries all the load on a Kensington hillside. Over time water works into the footing, and the post cracks out of its base. We excavate around the footing, re-set the post with proper depth, and correct the gate’s swing plane. The panel usually stays.
Sag Correction and Gate Realignment
A gate that drags at the latch side has a sag problem, nearly always traceable to the hinge side. We realign hinges, shim or replace hinge bearings, and re-balance the panel so it opens and closes without dragging across the driveway slope.
Gate Welding in Kensington
Gate Welding in Kensington covers cracked frames, broken hinge brackets, and rust damage that has eaten through steel. Hillside properties take the worst of it: wind off the bay, moisture held against the hill face, and gates that have been racking against a misaligned post for years. We weld in place when we can, and we know when a joint is safe to weld versus when the metal is too far gone to hold.
Welding repairs in Kensington typically run $180 – $480 per job, depending on the joint and access. A broken hinge bracket on a single swing gate sits near the low end. A frame crack that requires gusseting and reinforcement runs higher. We quote the number in writing before striking an arc.
Frame and Hinge Bracket Welding
Steel gates crack at the corners and at the hinge mounts first. We grind back the failed weld, re-weld with proper penetration, and add reinforcement plate where the original design was under-built. The result is a joint stronger than the surrounding steel.

Rust Repair and Patch Welding
Kensington’s coastal moisture and hillside drainage patterns mean rust starts low on the gate, where water pools. We cut out the rotted section, weld in fresh steel, and grind it smooth. If the damage is structural, we say so plainly and price the replacement honestly.
Trusted Brands We Service in Kensington
Kensington homeowners have gates running on LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule operators. Our technicians are factory-familiar with all nine, not just the two or three most common. For Kensington calls, we stock local parts for Linear, Ghost Controls, and DoorKing, plus the frequently-failed boards and sensors for LiftMaster and FAAC. That means many repairs finish in one visit. If we need a part we do not have on the truck, we tell you honestly before you spend a dollar on labor.
Common Gate Repair Problems We See in Kensington Homes
- Hinge posts settled into hillside footings. The post cracks out of a stepped or retaining-wall base, the panel sags, and the gate drags on the high side of the driveway. The panel looks fine; the post is done.
- Slide gates that grind and stop halfway. On sloped Kensington driveways, the rack and pinion slips out of mesh when the gate moves uphill. The operator strains, the gate stalls. The fix is re-leveling the rack and checking the loop detector, not replacing the operator.
- Operators failing UL 325 entrapment protection. We find safety photocells and edge sensors that were never installed, are misaligned, or fail reversal testing on older installations throughout Kensington’s 1970s subdivisions. This is a safety repair, not an optional upgrade.
- Low-voltage wire runs damaged by hillside drainage. Control wire buried across sloped yards gets nicked by garden tools and degraded by water. The operator loses communication with the keypad or safety edge, and the gate behaves erratically.

FAQs About Gate Repair in Kensington
The hinge post has settled. On Kensington’s hillside lots, posts are often set into stepped or retaining-wall footings, and when the footing moves, the post leans and the gate drops. The panel is usually straight; the post is not. We re-set the post and realign the gate, which runs $285 – $650. Call (903) 417-0793 for a free estimate.
Yes, and it is an urgent one. That behavior means the UL 325 entrapment protection, either the safety photocells or the reversing edge, has failed or was never properly installed. We test, replace, or realign those sensors, and we always run the full reversal test before leaving. Repairs run $195 – $450 before parts. Call (903) 417-0793 to schedule.
The rack and pinion has gone out of mesh. On a sloped driveway, the gate fights gravity, and when the rack shifts even slightly, the pinion grinds and the gate stalls. We re-level the rack and check the loop detector. This repair is usually $285 – $550. Call (903) 417-0793 for a written quote.
Yes to both. Our technicians are factory-familiar with LiftMaster, FAAC, Linear, Ghost Controls, DoorKing, and four other major brands. For Kensington calls we stock Linear, Ghost Controls, and DoorKing parts locally, plus common LiftMaster and FAAC boards and sensors. If we do not have the part on the truck, you know before paying for labor. Call (903) 417-0793.
Most repairs finish in two to four hours. Hinge post re-setting takes longer when footing excavation is involved, often four to six hours. A proper installation includes groundworks, power run, safety edges, reversal testing, and operator programming, and it is scheduled, never promised same-day. Installations in Kensington run $4,800 – $9,500 and include a free measure and written price. Call (903) 417-0793 to book a site visit.
If your gate is sagging, grinding, or refusing to reverse, call Calder Gate Repair at (903) 417-0793. A live person answers, the technician arrives with a trackable time, and the price is in writing before any work begins.
