Mark Thompson leads every job. You’re not getting a trainee sent under a brand name — you’re getting the technician with 17 years of gate-only experience, factory-familiar with nine brands including FAAC, BFT, and Linear. Our Gate Parts & Welding team carries common hinge sets, latch hardware, and V-groove rollers on the truck, plus a portable welder for structural repairs that can’t wait.
We know Belmont’s split personality: the flat neighborhoods near El Camino Real with their post-WWII ranch homes and original wrought-iron gates, and the hillside streets climbing toward Belmont Hills where clay soils shift and sliding gates fight gravity. That local fluency means faster diagnosis, fewer return trips, and repairs that hold up to what this specific environment throws at them.
Our Gate Parts & Welding Services in Belmont
Hinge Replacement
Belmont’s persistent marine fog — fed by bay moisture and coastal fog funneling through the Peninsula — keeps gate hardware in near-continuous dampness. Steel hinge pins and latch mechanisms corrode within 5–7 years here, causing gates to sag and bind long before the motor gives out. We replace with stainless steel or galvanized hinges rated for coastal exposure, and we see this pattern so often in Belmont that we stock the most common sizes on every truck. A typical hinge replacement in Belmont runs $180–$320 for a standard residential driveway gate.
Post Replacement & Custom Welding
On hillside lots in Belmont Hills and above Ralston Avenue, clay-heavy soils expand and contract seasonally, tilting gate posts and misaligning tracks. We don’t call a third-party welder — we cut, fabricate, and weld new post brackets or entire rail sections on-site. Custom welding for post repair or rail realignment in Belmont typically runs $350–$650 depending on material (steel vs. aluminum) and access. We’ve realigned tracks on properties where the original installer never accounted for the soil movement that’s standard here.
Rail Repair
Bent or separated gate rails are common where hillside gates have been forced against misaligned posts. We weld rail sections back to true, grind smooth, and repaint with rust-inhibiting primer. For Belmont’s coastal conditions, we spec galvanized or powder-coated rail stock that outlasts standard steel. Rail repair with welding runs $280–$480 for most residential gates in the 94002 area.
Custom Welding & Fabrication
Our portable MIG/TIG rig means we can fabricate custom brackets, extend gate frames, or repair cracked welds on vintage wrought iron without hauling your gate to a shop. This matters in Belmont, where many 1950s–60s El Camino Real ranch homes still carry original decorative ironwork that can’t be replaced with off-the-shelf parts. Custom fabrication starts around $400 and scales with complexity.
Gate Rollers
Belmont’s damp environment destroys standard steel rollers. We install sealed-bearing nylon or stainless steel V-groove rollers that resist corrosion and handle the debris that accumulates in hillside track installations. Roller replacement runs $120–$220 per gate, and we carry sizes for most common track profiles.
Latch & Lock Hardware
Strike plates and magnetic locks fail early in Belmont’s fog corridor. We install marine-grade stainless latches and weather-sealed electric strikes that maintain contact reliability through the wet season. Latch replacement typically runs $140–$260.

Trusted Brands We Service in Belmont
We work on the brand you already have — no pressure to switch systems. Our factory familiarity covers FAAC, BFT, Linear, Viking, and five additional major brands, which means we source parts fast and install them correctly the first time. For Belmont customers, this eliminates the two-week wait for a part that “has to come from the factory” — we stock common FAAC and Linear operator hardware locally, and our relationship with BFT distributors gets us specialty components in days, not weeks. From a broken weld to a full smart-access system, one company handles the entire gate ecosystem.
Common Gate Parts & Welding Problems We See in Belmont Homes
- Coastal corrosion destroys hinges before motors fail. Belmont’s fog corridor keeps steel hinge pins and latch mechanisms damp year-round. We replace with stainless or galvanized hardware that lasts 2–3x longer in this environment.
- Hillside soil shift tilts posts and misaligns tracks. On Belmont Hills properties, expanding clay soils push gate posts out of plumb. We weld custom post brackets and realign tracks rather than replacing the entire gate.
- Wooden gates swell and pull hinge screws. The foggy side of Belmont keeps fence gates chronically damp; end grain rots and standard screws strip out. We use stainless lag bolts with treated wood inserts for a permanent fix.
- Sliding gates jump track on hillside grades. On the winding streets above Ralston Avenue, debris builds in V-groove tracks and downhill-biased load causes derailment — a failure pattern we see repeatedly in this specific part of Belmont, rarely on the flat east side.

We don’t quote over the phone for welding work — we need eyes on the joint, the crack pattern, the post embed depth. Estimates are free. Call (833) 848-0143 and Mark Thompson will schedule a look.

FAQs — Gate Parts & Welding in Belmont
Belmont sits in a marine fog corridor that keeps hardware damp year-round, while San Carlos’s slightly more sheltered position dries faster between weather events. We install stainless steel or hot-dip galvanized hinges rated for coastal exposure — standard zinc-plated hardware fails prematurely here. Call (833) 848-0143 for a corrosion assessment; estimates are free.
Sliding gates installed on the hillside grade above Ralston Avenue collect debris in the V-groove track, and the downhill-biased load pushes the gate off the rollers — a failure pattern we see repeatedly in this specific Belmont neighborhood, rarely on the flat east side. We clean and reseat the track, upgrade to sealed-bearing rollers, and sometimes weld a custom track guide to prevent recurrence. Call (833) 848-0143 to schedule a track inspection.
Yes — standard steel rollers corrode within 2–3 years in Belmont’s damp environment. We install sealed-bearing nylon or stainless steel V-groove rollers that resist moisture and handle debris without seizing. The upgrade pays for itself in longevity. Call (833) 848-0143 for roller replacement pricing.
Yes — we weld and fabricate in-house, so vintage ornamental ironwork that can’t be replaced with catalog parts is our specialty. Mark Thompson has repaired dozens of mid-century Belmont gates, matching original scrollwork and re-welding cracked joints without destroying the patina. Call (833) 848-0143 to show us what you’re working with.
Belmont’s fog keeps wooden fence gates swollen and heavy for months, while damp end grain rots and loses grip on standard screws. We drill out the stripped holes, insert treated wood or epoxy plugs, and secure with stainless steel lag bolts that bite fresh material and resist corrosion. It’s a permanent fix we guarantee through the wet season. Call (833) 848-0143 for a free look.
