Fast, Reliable Gate Installation Across South San Francisco
A new gate in South San Francisco usually runs between $1,800 and $9,500, depending on whether you need a simple pedestrian gate or a full commercial slide gate with automation. Most residential installs fall in the $2,400 to $5,200 range, and we quote the exact price before any work starts. We know the fog off San Bruno Gap and what it does to metal, and we know the 94080 and 94083 blocks where old 1950s posts are waiting to snap. Hal Gatewood has been running Gatewood Fence & Gate since 2001, and when you call (877) 610-2993, a live person picks up, not a menu.
Why Gatewood Fence & Gate Is South San Francisco’s Preferred Gate Installation Company
South San Francisco is a city of two halves. West of US-101 you have the older residential blocks near Grand Avenue, Sign Hill, and the tract homes built after WWII, where original ornamental iron gates have been soaking in salt fog for sixty years. East of 101, you have the biotech campuses along Oyster Point and Gateway, where automated slide gates cycle hundreds of times a day and the bay air eats through residential-grade equipment in months.
We understand both halves because we work both halves. A gate that looks fine from the curb is often failing underground, at the hinge post footing, where fog-season moisture has been doing its work for decades. We do not patch that. We dig it out and set it right.
Every gate installation in South San Francisco starts with a walk-through and a written price. No trip charge inside the county. If you have another company’s written estimate, bring it out and we will give you a free second opinion. We have been doing this long enough that we would rather lose a bid than sell you a job you do not need.
Our reputation here is built on showing up on time and standing behind the work. Every job carries the 90-Day Done Right Promise in writing. Hal’s name is on the shop and on every invoice. That is the oldest accountability there is.
Our Gate Installation Services in South San Francisco
Sliding Gate Installation
Sliding gates are the workhorse of South San Francisco, especially east of 101 where commercial lots, delivery yards, and biotech campuses need a gate that opens a hundred times a shift without complaint. A residential slide gate on a west-side lot typically runs $3,200 to $7,500 installed, with commercial units pushing higher depending on operator class and access-control integration. The salt air here is hard on rack and pinion rails and cantilever wheels, so we spec galvanized track and sealed bearing wheels from the start. When a customer comes to us with a slide gate that shudders or binds, we look at the rack teeth first. That is where bay-side corrosion shows up first.
Swing Gate Installation
Swing gates dominate the residential streets off Grand Avenue and the Sign Hill blocks, where driveways are short and property lines are tight. A new steel or aluminum swing gate for a single driveway in South San Francisco usually runs $2,800 to $6,000, including posts and hinges. But on the pre-1970s homes, the real variable is the hinge post. If the original 1950s post is rotted at grade, any new panel hung on it will sag within a year. We gave a bid on a 1940s row home off Grand Avenue where the old ornamental iron gate had rust-fused to a hinge post that was rotted clean through at ground level. We set a new galvanized post footing, re-hung a custom steel swing gate, and mounted a keypad entry with a safety photocell, because the salt air had also killed the old operator. The gate now opens smooth and trips the entrapment protection on cue. That is how a swing gate install should end.
Driveway Gate Installation
A driveway gate in South San Francisco has to do two jobs: keep the gate moving in weather that wants to stop it, and keep people safe. The fog that funnels through the San Bruno Gap and off the bay bathes operators, hinges, and safety edges in salt-laden moisture far more persistently than in San Mateo or Redwood City. We have pulled residential operators off 94080 driveways that were rusted inside the chassis after four years. For driveway gates west of 101, we recommend operators with sealed control boards and galvanized chassis hardware, and we always check the existing loop detector wiring before we promise anything. A full driveway gate installation with automation in South San Francisco runs $4,000 to $9,000 depending on span, material, and operator class.
Pedestrian Gate Installation
Pedestrian gates are the quiet workhorses of the row homes around Grand Avenue, where the original side gates were hung with whatever hardware was on hand in 1955. A new steel pedestrian gate in South San Francisco runs $1,800 to $3,200 installed. The catch is that the old posts are often too far gone to reuse. We do not hang a new gate on a post that has lost its integrity at the ground line. The price of a new post and footing is small compared to pulling the whole assembly out of the soil two years later.

Trusted Brands We Service in South San Francisco
We work on Linear, Viking, Ghost Controls, and DoorKing operators regularly across South San Francisco, and we carry the parts that actually fail here: sealed limit switches, galvanized rack sections, and control boards with weather-resistant coating. When a biotech campus on Oyster Point calls about a slide-gate operator that froze, we do not order a residential Linear actuator and hope for the best. We spec a commercial-grade DoorKing or LiftMaster CSW200 class unit rated for continuous duty. The operator that survives 200 cycles a day in bay-side salt air is a different animal than the one on a quiet Daly City cul-de-sac.
Common Gate Installation Problems We See in South San Francisco Homes
- Rotted hinge posts below grade. On the pre-1970s blocks west of 101, the original ornamental iron and chain-link gates were set into posts that have spent sixty winters absorbing fog moisture. The post looks fine at the surface but is hollow underground. A new panel on a dead post will sag, bind, or tear out the first time a fog-season gust hits it.
- Obsolete control boards that will not talk to modern safety systems. Many older residential operators in the 94080 and 94083 area still run boards from the 1990s that cannot communicate with current UL 325-compliant photocells or keypad entry. Retrofitting those boards often costs more than replacing the operator with a modern unit that meets current entrapment standards.
- Salt-fog corrosion on rack and pinion rails. Slide gates along the Oyster Point and Gateway corridors, and even residential slide gates closer to the bay, develop rack-tooth pitting that a standard residential operator cannot pull against. The gate starts to chatter, then binds, then burns out the motor.
- Fog-season wind load on worn posts. South San Francisco gets real gusts when the marine layer pushes through the San Bruno Gap. A gate post that is marginal in August can snap at grade in February, pulling the footing out of the soil and taking the fence section with it. Repointing the masonry is not the fix. The fix is a new post, set deep, with proper drainage at the base.

FAQs - Gate Installation in South San Francisco
Why do gate installations in the Grand Avenue and Sign Hill neighborhoods often require replacing the hinge post, not just the gate panel?
Because the original posts on those 1940s-to-1960s lots have been sitting in marine fog for sixty years, and the failure happens at the soil line, not at the hinge. You can bolt a new gate to an old post and it will look fine for six months, but the first fog-season gust will lever that post out of the ground. We replace the post and the footing as part of the install, not as a surprise line item. Call (877) 610-2993 and we will tell you honestly whether your existing post can carry a new gate or needs to go.
Can our old 1960s ornamental iron gate be retrofitted with a modern automatic opener and safety photocells?
Usually not in South San Francisco, and here is the honest reason. The gate panel itself, if it is not rusted through, can often be salvaged. But the operator and control board from that era cannot communicate with today’s UL 325 safety devices, and the hinge posts are typically too far gone to support automated movement. What we have found works best is this: keep the gate panel if the steel is sound, replace the posts, and install a current operator with proper entrapment protection. If the panel is too far gone, replacement is cheaper than chasing rust. We will show you both numbers and let you decide.
What type of slide gate operator do biotech campuses on Oyster Point need when a standard residential model fails?
They need a continuous-duty commercial operator, typically a FAAC, DoorKing, or LiftMaster CSW200 class unit rated for high-cycle use in corrosive environments. A residential model will burn out in months under that cycle load, especially with bay-side salt air degrading the chassis and seals. That is what we stock for those campus calls, and it is what we install when a standard unit has already failed once. If you are managing a commercial gate in the Oyster Point or Gateway corridor, call (877) 610-2993 and we will spec the right operator the first time.
Do South San Francisco’s marine fog patterns affect gate installation timing or materials?
Yes, on both counts. The persistent fog through the San Bruno Gap keeps metal surfaces wet far more than on the inland Peninsula, so we use galvanized steel, sealed-bearing hardware, and weather-coated control boards as standard on every South San Francisco install. Fog also means morning condensation on fresh concrete footings, so we adjust curing times when we pour post footings in the winter months. The weather does not stop us from working, but it does change which materials we order for your gate.
When installing a new driveway swing gate on a pre-1970s home, do we need to upgrade the loop detector and keypad entry at the same time?
In most cases, yes. The original loop detectors on those older lots are either dead or wired for a system that no longer exists, and the keypads, when present, are usually not compatible with modern UL 325-compliant operators. Trying to run a new operator with old detection wiring is how you end up with a gate that closes on a car. We install the loop, the keypad, and the safety edges as part of the job, wired to the new operator from day one. That way, the gate passes the entrapment protection test the day it is installed, and it keeps passing it.
